We Overclocked an AMD CPU to over 8.1 GHz !!

these are the heart of your system hi and welcome back to another extreme overclocking video in today's video we are going to cover FX 8350 extreme overclocking I bought the CPU many years ago and it was also the only CPU I bought the only FX 8350 and I was really lucky with this sample because it's extremely good it's one of the best I've ever seen back then it was like in the top 15 of the highest ever reached frequencies with CPUs I'm not sure which rank it is today maybe it's still top 20 we will try to reproduce the scores I did like four or five six years ago the reason why I want to revisit the CPU is because it has been sitting in a tray for many years I don't think it degraded it wouldn't make any kind of sense because I was practically not using the CPU at all and also back then I was using the Asus crosshair 5 formula and now I have an Asus 97 pro gaming our main board which should be better it has a much better VRM and therefore maybe we can squeeze a little bit more out of the CPU I also attached a very nice new feature to this this small PCB let's take a closer look at this quick look at the setup 970 pro gaming era currently running with an AMD box cooler we have 2 dims Corsa ventures and Corsair engines 2666 very good dims probably some of the best ddr3 dimms that have ever been made an nvme drive where Windows 10 is running from and then we have this small pin header right here typically those pin headers are not populated on a stock board it's just empty solder pads but I attached a three pins to it and on a cable we have an elm or EB C 2 PCB the ELMO EB C is using I - C or I squared C depending how you want to call it I used the connection number one and then collect find devices then it detected the CH l 83 28 v RM controller it's also called I think the ASP 1000 C something like that on the chip directly anyway if we click on the voltage controller on the Left we can access it over I to see and the PM bus we have all kind of values which we can read out also manually change for example switching frequency 300 kilohertz currently you can read out some load line calibration values really interesting stuff you can read out right here if you click on a PM bus we get full access and monitoring of for example CPU voltage and also output power which is kind of interesting I'm not sure what we know this doing in the background right here but you can see like idle power it's just a few watts and then in between it cycles back up to like 10 20 watt no idea what the windows is doing right there anyway we can for example also access and change the CPU voltage which is the main thing we are going to need especially on some boards all the board's where you don't have lnto bios and you have like voltage limitations sometimes you cannot exceed for example 1.5 5 volt here you can see if I just scroll down I could theoretically set 2.5 volt I mean this would end the CPU pretty much something I want to avoid currently it's set to 1.3 - I can just lower it to 1.3 for example if I want to you have to set the gamer mode to enabled PID type override apply changes and then for example output voltage is currently monitored right here it's 1.3 to 6 if I apply it goes down to 1.3 world so that's a very very helpful software and feature by the way the EBC 2 also allows additional features like spi BIOS flash you can theoretically use this to flash bios versions which are not meant for your mainboard I remember back then when we did the epic overclocking we also used the EVC 2 and at that point we were flashing and msi bios on an asus port which was only possible with the EBC 2 and then it also has additional features where you can change voltage test not only with digital controllers like on this one but also on analog stuff similar to Asus Hotwire I think we can cover that in an additional video if you're interested in that it's a very very helpful device so if you're interested in this like extreme overclocking stuff maybe go to a Moore's website and check it out in today's video we are mainly using it to keep track of power consumption and also to be able to change voltages on-the-fly sometimes if you really running on the edge and CPU is unstable I don't know it 8 gigahertz sometimes it looks like it crashed but it didn't really crash sometimes if you manage to increase the voltage slightly then the system gets back you can kind of recover it and keep going with the overclock that's why external overclocking over the software can be really helpful that's why I'm going to use this device today I'm not sure if I should hate myself more or the AMD socket again in the CPU stock so the cooler and unfortunately when I pulled it all that bent some pins I really hope I can bend them back and rescue the CPU this would be this would suck so hard [Music] CPU back in the socket I hope everything still works put on the ln2 container quickly for this test before we're going to insulate the mainboard and prepare it for ln2 also have an PCI debug card on there simply going to test if everything still works before we start with the preparation looks good yeah everything is fine all of those older AMD FX CPUs like the ad 350 or 95 70 or like an FX 4300 all of those can run full pot means we can go down to just about minus 190 degrees Celsius therefore we will have some ice building up some condensation in this area not really any in this area not really an issue typically because it's too cold in here we won't have any kind of condensation worst case we would have some ice on there ice is not electrically conductive therefore usually doesn't cause that many issues however in a region of heat things where parts are underneath that are generating heat you can easily get like an transfer layer where you have ice on top and then condensation on the bottom same goes for the vrm that's why we will have to remove the heating's make sure that all the parts underneath will be insulated [Music] sometimes if you remove heat things which are using thermal pets it looks like this underneath it looks like something is wet and that's just silicon oil which comes out from those thermal pads it's something that's happening very often it's nothing dangerous the silicon oil is not conductive therefore no problem but we're going to use liquid rubber insulation which is kind of like paint therefore we will use some acetone to first remove those silicon oil residues [Music] almost good to go insulation is dry most of the components are back in place the only last things which are missing is thermal paste on the CPU obviously the CPU cooling device temperature probe inside the CPU cooler and then a little bit of paper towel around CPU cooler to catch any kind of condensation drops and anyway good to go everything is ready to go you can probably hear it there is already a tiny amount of liquid nitrogen in the container but mainly to maintain temperature around 30 degrees Celsius in the container right now just running the Cinebench r15 multi to see if everything is stable with our base setting you can see the CPUs clock to 3 gigahertz across all the cores with just about 1.5 volt which is obviously too much for three gigahertz across all cores but we will keep all modules at this speed while we will only up probably the second or third module we will have to figure out which one is the best memory is running at 2,000 megahertz cl9 more EVC software is also running very smoothly you can see currently we're running about 160 watt in Sandwich r15 and the temperature is if we move to the right about you know 78 degree Celsius in the VM which is fine there's no air flow on it right now and quite a bit of current therefore that should be fine [Music] [Music] unfortunately as usual with the extreme overclocking things are not going as smooth I'm currently sitting at one minus 130 degree Celsius and if I hit about minus 160 it shuts down and those specific CPUs should not have this and I'm trying to figure out what exactly is wrong yeah typical I think I tried it like 15 times before disabling stuff changing like PCIe frequency nothing help disable some onboard devices and now it seems to be working awesome great I thought I could show you how it's not working but now it's working even better and that's how easy we could get to seven gigahertz currently running 1.9 volt on vcore in my abc I said 1.5 volt it's currently loading with about 50 to 70 watts about 30 amps for EMS erm temperature cannot go lower than 1 degree Celsius in readout [Music] [Applause] [Music] there we go 8 gigahertz on the cpu 8.1 gigahertz actually there you can also get an idea how much stress it can be for a mainboard to run at those kind of temperatures that's mainly related to different PCB layers different copper layers that are running through the board and then you have different thermal expansion rates because it's not always the same amount of copper at every single position and running it at minus 180 degree Celsius can cause stuff like that I've been trying it about 10 times already to hit the 8.2 gigahertz mark still working on it but system is still running nice and smoothly even though there's no insulation [Music] still really happy with the system I think I've been running for like two or three hours right now I mean there's building there's some ice building up on the system but seems to be no problem temperature - 175 at least that's what a temperature probe is reading it should be colder than that and out of pure curiosity I'm just running as a matter of 15 single-threaded at 7.5 gigahertz and I think or my assumption would be that even at this speed this CPU should be slower than a current rising at stock 172 points that's more than I thought that's just above of 4770k let's see if we can squeeze out a little bit more during the benchmark and see the power consumption it's just about 100 watt and considering that we're only running a single core that really is a lot unfortunately that's already the end of the video because I simply ran out of ln2 I only had 30 litres and they also had to use them for a different CPU and you will see that video coming up in a few weeks stay tuned for that so much for the 8350 revisit very very nice CPU it's still a lot of fun because it's very unique it's only this specific platform and those CPUs which can achieve those very very high frequencies even I mean nowadays Rison there is no chance they end up at like five point five gigahertz with Ellen 2 maybe 6 gigahertz if you do like validation stuff but not much higher recent interviews can hit just above 7 gigahertz with Ellen - maybe like seven point five seven point seven on liquid helium which is obviously something I cannot use here but 8350 is still a lot of fun to play around today and it's also interesting that even if you push the CPU to almost 80 Hertz on a single core it cannot get a single core performance of like a risin 3000 CPU it just shows how much ahead horizon 3000 is back comparing this to the am-3 platform so much about this video we will end this video with some close-up shots of this beautiful system thanks for joining in and see you next time bye [Music] [Music] [Music] you [Music]

Wow! Pretty impressive. Shame that bulldozer was such a garbage arch, but I'll be dammed if the 8350, 9370, and 9590 can't hit absurd clockspeeds even still.

[u/just_buy_a_mac]

I remember getting my old fx 8120 @ 4.9ghz stable for at least a year.(pretty amazing for a 3.1ghz base clock)

But that thing sucked power like no ones business and could not keep up with i7s at their base clocks lol.

[u/cp5184]

That 175% vrm efficiency...

[u/Jannik2099]

I wonder what power8 or z14 / 15 can OC to. Those things run 5GHz stock in a server environment

[u/paddington01]

It drew over 100W for a single core.

[u/Alienpedestrian]

I Need this type of cooling for my 2015 pc combo fx9590 and r9 390

[u/AMD_PoolShark28]

I too look forward to the day that I can get my AMD processor over 5 gigahertz. I just need time and a -40C day outside in Canada

[u/NonToxic628]

Call me back when it’s over 9000!!!!

[u/Tenzo590]

Can someone ELI5 the speed meaning? Is this read speed! Is it a disc’s spinning speed? I get it’s a cycles per second, but cycles of what?

Thank you in advance and sorry for being a dumbass haha
