HOW IS THIS POSTING??!??!!? | H110 BTC PRO+ REPAIR Mainboard Damaged CPU socket repair

hello and welcome today I want to show you how it looks like when you get scammed on eBay this is a Bitcoin mining board or like in crypto mining board where you can attach many graphics cards uh and yes in Bitcoin with graphics cards sorry for that but you get the gist of it this is an h110 Pro BTC plus and why did I get scammed well the owner told me that this board still boots up but it crashes and in the very first moment I I opened up the package and looked at the sport I knew why let's show you I know it's kind of hard to see in the reflection but this is how our p uh CPU socket looks like let's go together under the microscope and see why it is Crash so now under the microscope let's go over this bit by bit you have this pin right here that is a little bit bent out of place this wouldn't be this wouldn't worry me too much you have this pin right here that completely looks the other way let's Bend this out of the way you have this pin I can already tell you I won't be putting in too much work for this Bard because this socket is awful will be a miracle if this board even ever boots and this pin is almost about to break off okay let's not touch that one anymore let's do this one also once more getting it a little bit more into the Direction Where We need it I'm going to be a little B bit more rough with this board because as you could were already able to see this board has very slim chance to ever boot or work again so I'm not too too worried about breaking something now let's go to the next position where I saw a pin which could be very bad which is this one which was completely folded on itself let's see I can get you I think this pin is also toast and then you can also see this one in the top right and it's head snapped right off this might be a little bit my fault as well because I'm very rough with them but still yeah there there wasn't much holding that on anymore then let's see I'm going to leave this pin like that let's let me see we have a pin here okay still isn't good because the way it is bent still not right but let's keep it like that for now there and there's a lot of pins oh there might be fine they look kind of out of place but I think they might just pass this one right here definitely does not pass this one needs to go more to here let's leave it at that now we're going to get into the awful parts of this main bot because what we've seen before was the the good parts and now we see the the ugly parts of it let's see now this pen needs to go here this pin what happened to this one man this is awful let's see I don't think this pin will ever make good contact again let's just make sure sure that it won't short out anything else just like this bad boy right here and also this one so let's move on having fixed can't even tell say that with a straight-faced fix those pins let's see this is the other bad Corner let's see I I I don't think I've ever seen this much damage on something that wasn't like intentionally broken and where someone told me that this bought boots because this is like there I've seen damage where like people drop a CPU in there or something like that or get stuck on something and like dislodge maybe two or three pins but this socket has this damage in multiple corners of the socket yeah I'm I'm actually not too sure what to do about these pins because they're so Bann out of place that I can't even get them as they were before because as you can see in the bottom in the bottom corner they are bent and I can't bend them back from there okay like I I I don't like this like how this pin is like still way too far to the right but we're going to keep it at that for now because as I said not not much hope for the spot there's the next pin that looks bad which is this one Al not too much I think that we can do for this one and that one up there compared to the other ones these look very good compared to what we've seen so far okay um this is the furest I want to go right now like there's also some here I think we've been here before but let's let's keep it at this for what we've tried um there's no more that I would say that are like directly touching different ones that they shouldn't um most of them are awful like these ones I tried to get them as much as I can in to a position where they're supposed to be and this corner is just awful like this is really bad the way that the some of these Bend is like really really bad and I'm kind of scared to do this because it's probably not a good idea but we're going to plug a CPU into this and put Power into this and we just going to see what will happen um I'm very well aware that putting a CPU into this might very well kill this CPU and lose me even more money um but we're going to try it anyway this is a six Gen processor this is a ceron probably the best thing to sacrifice if to sacrifice anything let's get a stick of ram into here so we have everything built up this might be one of the worst things I had so far to do on this channel but let's see if it blows up in Flames going to get our power supply onto here and let's see yep that's pretty bad that is 50 500 milliamps of consumption but actually starts up this is very weird because we also have postcards running and the power consumption doesn't look as bad let's see if we actually get a picture out of this because this seems to try to boot up right now and to the surprise of absolutely no one this board does not display anything even though my DDR test actually goes to AF which means Boot and it actually if we reset it but there's no sign of Life on here and I also have a keyboard attached to the USB and we don't have any indication of life so we don't get the numlock uh LED on the keyboard but I I have to say this board got further than I expected it to to to get already let's check for some voltages we have 1.8 Watts here this should be two and a half Watts I think this should be VPP oh interesting this is4 volts we might have to take a look at that there should be 105 volts yes this is the PCH then we have what is here we have 1.2 volts on there let's go on to DDR we have 1.2 volts on DDR Let's see we have I think this is supposed to be V core see here yep one volt so all of these look good the only one that seems to be off is this one right here4 volts there might actually be a chance for this board weirdly enough um let's see this should be 3.3 volts yes this is the 3.3 volts so let's have a look what this is supposed to be what I can find about this one because I have a board re for this board and um let's see what this powers and if we have any problem that we can recognize there and now we are back on our board View and the inductor is this one right here pl12 as you can see it is a 3 vsb slot phas so this goes to here goes to half of the PCI slots and now if we go over to our overhead cam again if we take our propes and measure this we have almost zero ohms two and a half ohms my props have very lower resistance almost zero so we have a 2 and 1 half ohms short on a 3 volt phase we are going to try with voltage in ction we're going to put three volts into there we're going to see if we can if anything gets hot and now something very interesting happened I've now lifted the inductor from here and I've put on the output a wire but as you can see when I probe this place where I attach the wire to you can see we have high resistance resistance like very high resistance and if I go on its input we see the short circuit that we've seen before so this thing isn't shorted on its output but on its input which I didn't expect at all um to be very sure I can show you the board view um I have attention to the left side and we saw that the left side has high resistance and and this side has the low resistance and the only thing on this side is this stepdown converter so what we probably need to do is we're going to desolder that stepdown converter see if our resistance goes up and then we're going to supply our own three volts to it onto this part and we're going to see what happens and right now you can see the controller um I've just injected some volts into there three volts to be exact into the actual output of it so into there and the thing got really hot it got to like over 100 degrees within a second so the problem with desoldering it is that we have a plastic connector for the battery right there so what we are going to do is we're going to flood this thing with let us sld on both of the sides because there's no way no need to save this because it is 100% dead so let's use our big soldering tip and let's just get a big blood of solder onto there and we're going to do the same thing right here and let's see can we get it wet enough like this no I don't think we will okay so what we're going to do is we quickly going to run the hot air even though we're probably going to melt the plastic connector but um don't really care too much about this sport so let's run our hot air we have 400° and 75% air flow and our connector is already melting as you can see but we have the part removed only a little bit of the connector got melted don't really care about that because the functionality is still given what we now need to do is we now need to clean up those paths so we're going to be using some sld Wick and yes I could be working with a lot more flux here but the lettered solder should be enough I just want these to not be bridged anymore and just like that let's clean up at least a little bit so you can you can assess the situation a little bit better and as we can see now our bug converter is removed let's now check for the resistance we're going onto our overview again and let's get a microscope out of the way you can see my multimeter and because it's the only component it's not going to be a short here anymore it's not going to be a measurement at all and one thing I'm interested right now is will this boort actually work like this so this with this removed because the thing is we saw uh strange behavior in the power and I saw on the board view that this thing is fed by 5 volts VSP so something that is always running so one of the standby voltages so this might actually work without that power rail because that power rail is uh for pcie I think specifically and we can check it in The Bard view once more let's go into the board View and this connects to a couple of places right here this is ground this is ground is are resistors these also go these are feedback uh capacitors I meant these are capacitors because because they're connected to ground also and are these all also capacitors these might be all capacitors also this is some sort of of signaling this but I think this all only going to the PCI slot so what we're going to do is we're going to use the integrated Graphics of a CPU to see if this board actually will turn on um without that power rail so let's see that together we get our power supply on here um let's let me plug my DDR tester in here as well let's let's turn this on this is three volts and we need 12 so this current consumption actually looks normal like 120 MMS is more than I would expect for a bot like this where there's like no LEDs or anything but it's still nothing where would be highly suspicious of so let's see now together turn this on let's connect also a display output to here let's also connect a keyboard and the current consumption definitely looks different we have way less current consumption than we had before but I don't think we are posting it's still stuck in the same loop as it was before um let's check for some voltages again but I think this time there won't be any problems anymore we have 1.05 we have 1.8 which was this um this two volts shouldn't this be 2 and a half volts this might be still a problem this is two volt this might this might be VPP that is supposed to be 2.5 volts we're going to check that if that is VPP and if uh we are on the right side of the inductor this is 1.2 volts um this is also 1.2 volts but this is for this controller and the one that we had at the top was for DDR um okay well this the interesting thing is on this inductor we had 1.8 volts before and I thought that was correct but this might be VPP where we need 2 and a half volts so let's go over to our Bo view once more let's get this out of the way we are on our board View and this was this inductor and this is vppm this is supposed to be two and a half volts I'm pretty sure um let's check at these outputs of these this resistor right here because I was checking here and it might be a little bit different of a voltage on this side um let's go over to this View and let's see we're going to turn it on again we're still in voltage mode and let's see on that resistor yeah 2. so that's just probing from the wrong side of the inductor so we have 2.5 volts on VPP so this is right and if you go on this side we have two volts but we have 2.5 on the output so that that is totally fine um yeah let's try to see what happens if we put 3.3 volts on to the output of this if there's anything going to change then and right now we have the bolt connected to our server power supply so you can see in the top right here and we have the we have 3.3 volts on our multi uh on our La bench power supply we have one ground connected there and then we're going to use this wire down here that is connected to the 3.3 volts and let's connect this this has no current draw so far and let's start start this up now we can't see the current draw anymore sadly of the board because we knew using the power supply for injecting 3.3 volts but there's no power consumption on this 3.3 volts which is odd so this is not even needed I think should be good and we still get no post so this was not the problem for it sadly let's try something different let's see if my connection is good yeah as you can see the connection is good so 3.3 volts is not being utilized at all um the next thing I'm going to do is I'm going to flip the DDR slots and we're going to see if that makes any difference I cannot believe my eyes right now how how is this board posting what the actual I I cannot believe that this board is turned on and this is not a fluke um I can I can show you it differently let's turn this off again we've turned it off and let's connect the this power supply to it so right now the board is off the picture that you can see in the top right is just the Frozen picture of what we had before and now we can going to see the current consumption together um the three .3 volts is not hooked up to this anymore and let's turn this on the current consumption looks pretty similar to what we had before well now it's 1.8 it's less and as you can see we have a picture we got into the BIOS let's go into the actual bios but as you can see in the top right we are in BIOS and I can can go around this Bard turned on how is this possible how you've seen the slot you've seen the CPU socket I can't believe that this is working it's just ridiculous as you can see this is the keyboard I'm using it is actually on cannot believe my eyes right now and I think um some of the USB ports are dead because the these USB ports didn't work uh we're going to find out out if eanet is going to work let's turn this off because I also don't have a heat s on there um I'm going to put a CPU heat sink onto here we're going to go into windows together and now I got everything plugged back in and got a heat sink on there let's see if it goes into Windows the big thing that you need to understand here is this is a mining main board this is specifically focused on just running a lot of pcie so if the CPU isn't going to give its full power nobody cares if only one of the two Ram slots is detected nobody cares because this is a mining main board this the shorted uh bug converter that we saw that is a problem because that is responsible for the PCI slots so we do have to fix that in order to make it work but the only other thing that I think is important for this thing would be the um the ethernet to work because that's an only thing that they they would care about so let's see now if this connects to Wi-Fi because we're already in Windows and as as as you can see it looks like we are connected to um not to Wi-Fi but to ethernet it's ridiculous I cannot believe this is working let's connect the mouse onto here and let's run at least a single stress test for the CPU because the CPU also needs to be stable for miners to care about it because they want their rigs to run long term okay um let's see these USB ports aren't working I think yep and now the keyboard is detected we have ethernet it's working as you can see it's loading sides I cannot believe this I'm going to run a stress test I'm going to run a um a single run of lint pack this time not the big one just a small one so we're going to do stress test uh two gigs one cycle and I will see you again as soon as this will have finished and I cannot believe it but it passed so the next thing we now need to do is to fix the 3.3 volts um regulator and you might not believe it but I might have that part in stock let me check quickly and now I found the part this is an MP 2143 I Once Upon a Time bought a five pack of these and there are still two left in there why do I have these the interesting thing is the very first mainboard that I fixed was an h110 Pro BTC Plus this board or this model of board was the very first time I tried to repair main board and guess what also was blown up on that um there was a lot more wrong with the very first main board I fixed with the very first h110 BTC Pro Plus but that thing still works to this day and I've changed a lot of things on there there was this regulator blown there there was this chip blown this regulator blown and that regulator was blown and also the face on the memory was blown there was an awful power search on that board and a lot of things were were killed uh on that board but I still got that to work and I I I probably will never forget the way I fixed that board because back in the day I wasn't really couldn't saw really well or anything wasn't very confident in my fixing skills and have never fixed ATX main board before and there was so many faults with this board that I thought I'm doing something wrong but it worked out at the end for me and that's why I still have components left over for this exact board the other thing would be I actually have donor board an h10 Pro BTC Pro Plus that has a dead PC so I could have even taken that component from there but we got lucky and I actually have uh new ones I think these are new um let's prepare the place where we need to solder um we're going to add some flux right now and now we have flux and now let's add some Leed solder to these pads and now we have Leed solder and um what we're going to do now is we're going to uh take out a component so we now have the regulator right there and what we need to do next is we need to find out where pin one is and where it's supposed to go pin one would be the one at the top left and now let's go into the board view together and see so um pin one is in the top right corner but I cannot tell you if that lines up with our if that lines up with our bug converter um I'm not too sure how to place it in there but we're going to just going to use it like this and we're going to place it in there and we hope that it's going to be correct I'm going to be soldering it by uh heating it up from the bottom and so that we won't damage the the battery connector anymore and we're just going to hope that this is the right orientation because there's no way for me to check because there are no dots on the uh on this bug converter or anything but we not I'm going to solder this on off screen and we're going to see each other again when it's slded on and now the chip is soed now I'm going to connect my probe so we see the power consumption and we have and it's dead yep that wasn't right that just started smoking well then um let's check its resistance and I I think it just died so I think it might have to has to be the other way around let me quickly change that out for a different one and we're going to see each other again then and this time we've switched the orientation this way and let's see if that is going to be right I might leave it like this because if it goes up and smokes and flames you will able to see it like this um let's get this better in spot so our power supply isn't in the way now you're going to be able to see the power supplyer also and let's turn this on and this is not connected um let's connect our ground probe and see what will happen one two and three and this looks very promising now it didn't blow up and I'm going to prob it quickly and we have 3.3 volts that you can see let's see um let's go to and now you can see my multimeter and now we have 3.3 volts as you can see and I got to say I probably did that before already pretty sure I've killed one of those chips before like that also because there's a reason why I had five chips originally and with fixing a single B I only had two left so I think this happened to me before and I can very well see that happening to me so what we're now going to do is I'm going to spend quite some time building this up because I want to test with at least three or four graphics cards to see if this will recognize all of them so we will see each other again when I have abundance of graphics card built up and we're going to see if they are going to get detected or not so this is the first time for me as well as you can see we have two graphit card right here this is a 6 760 TI or something like that and the Vega 64 we have the gt310 and we also have a Quadro 2000 plugged in right there what we're now going to do is we're going to turn this on the we sge on the server power supply there now you you can see some fans already spinning some are not and let's press the power button on here it seems to be turning on now we are booting and why I do this is we need to see if this recognizes multiple gpus in these slots because that is what this thing is made for and as you can see we have picture let's now try to get into Windows and then we're going to see how many of these cards are actually recognized um Windows is actually bad to recognize a lot of gpus um I think for should be still fine but you would want to use some sort sort of Linux for this but let's see so we do get an output from the gt310 this is that is that let's see if the quadro the Vega and the this Nvidia card is being recognized um I'm going to switch the output on okay I so as you can see there's our windows and it's going to be quite tough because I have to now hold my capturing device with a single hand and now let's go into our device manager and let's see we have two graphics card already detected in two more display adapters so we have a Vega the Vega and the gt310 and now I'm going to wait as you can see there's some drivers probably installing for some of our video adapters and right now all four graphics cards are detected don't know why there is still an arrow especially on the gt310 because we are displaying from that graphics card right now but all four are recognized and I think this board works the way it should be I cannot believe that this board works this has been such a roller coaster of a fix I've never had that ever before on any main board we had an absolute smashed CPU socket where I would never have thought that any CPU will even even not get killed in there but yet alone works Ram is detected we're booting up into Windows it is stable we have done stress test to the CPU and then we even had a buck converter that was shorted a 3.3 volt Buck converter and then I even had the part on hand I installed the part backwards killed the part and then installed the right one and now we have this main board working I think there's still some USB not working but I don't care most of the main BS don't need USB anyways and some USB are working we have multiple PCI slots working which is way more than we need we have S working nvme probably works I'm not going to test it now but I I'm just Flubber gusted I I cannot tell you how impressed I am that this Bol works I probably should never remove that CPU and that cooler just to be sure that works like it is but I hope you enjoyed the video I hope you learned something in the process on this roller coaster of a fix I hope you found it entertaining hit the Thumbs Up Hit the Subscribe button thank you very much for watching this was mainboard medic with an insane fix on an h110 BTC Pro Plus thank you all for watching see you
