-Greetings and Blerbs
and Intel OverDrive Processor things, look at this! Got a lovely sealed 486
DX4-100 processor here. [excited tapping] Yeah dude. I've had this for a while now and I've been meaning to put it in my LGR Woodgrain 486 for a while now. Although it's not been the Woodgrain 486 ever since I upgraded it
to a Pentium OverDrive over on my LGR channel. See that video if you haven't. I wanted to switch it over to this because that Pentium
OverDrive, while cool, it's not really the spirit
of what I wanted to do with that machine when
I initially built it. And this isn't really either,
but it should be awesome, and I've always liked these processors. I've got one of them in
my Compaq Presario 425. That thing is great. It's been in there ever since
I got it in high school. But yeah, got this one sealed. I'm gonna see if it makes any difference. I don't know. It's not gonna be mind blowing. In fact, I don't know if it's
gonna be any faster or slower. I just don't know. I haven't actually tested
or compared the performance of a 486 DX4 to the Pentium OverDrive. So I don't know, just curious to see what
the difference will be, so we'll compare the two, and that's what this is. So in particular is a DX4ODPR100 and that means OverDrive
Processor Replacement, ODPR. If you see the R in the
name of these things, then you know that it is
a specific type of thing that is meant to drop in and completely replace a PGA 168 socket. However, they also had this one. So this is essentially the
same chip, but this is the ODP. So this has an extra pin on there and you'll need to put
that in an upgrade socket, or like a secondary kind of thing that's separate from the main CPU. I actually sent another
one of these that I had over to Adrian Black,
Adrian's Digital Basement. He put it on his second channel when he did a unboxing
and set up video for that. So yeah, I recommend his video too if you wanna see a little
bit more in depth on that. And anyway, yeah, I gave him
this replacement version. It's more versatile, you
can use it in more things. Whereas with this one, it's
got that weird little extra pin just kind of right in the middle. Whatever. Let's get this unboxed and installed. And yeah, I ended up with a
bunch of these boxed and sealed, which is why I've been sending them out to other YouTubers and such. I just got them all in like
a job lot auction years ago and they've been sitting in storage. Time to use this one. Now, the way this comes off,
it just sort of ruins the box. I don't know if I wanna do that. I wanna see if I can, like, 'cause this thing just
rips apart and blah. There we go. Keep that intact. Put it back on a shelf as a display piece. Heck yeah, look at that! Reclosable chip container,
in a lot of languages. All right, so that is
the OverDrive DX4ODPR100. Yeah. Got some voltage regulation there, so we don't have to worry about that. And there is no additional
center pin there, so yeah, you can just plug
this into your normal PGA 168. I suppose that makes
the other one PGA 169. Nice! Normal 168 here, looks like the pins are all looking good. And we get a little accessories packet. Don't see any Coffee Instant Type 2, but we do have a nice
little PGA chip puller deal. These do tend to bend somewhat easily and the edges are really sharp. I'm not a fan of these ones that Intel included in particular. But you know, they do the job in terms of pulling things out when you don't have a ZIF
socket or anything like that. But thankfully the one that
I have in there in the 486, don't have to worry about that at all. Oh yeah, we got this little disc. OverDrive Processor
Demonstration and Diagnostics, version five. Registration. Whee. And of course, some instruct-ee-oh-nays. 1995. Before I begin, on most computers installing
this crap is simple, but if it's not, it might suck. That's pretty much how these go. It is very simple. You just kind of plug it in and most of the configuration
is down to your system. So it's either going to handle
all the voltage changing, you know, clock multiplying,
all that stuff on its own, but probably not, and definitely not in the
case of my system in there. I'm gonna have to refer
to my documentation for my particular motherboard, because there's things to swap around for the motherboard to know what type of CPU's going in there, 'cause right now I have it set to P24T because that would be
the Pentium OverDrive, but this is different. I'll see. Anyway, go ahead and get
this installed real quick and we'll test it out. Good times, good times, good times! All right, so out with
the Pentium OverDrive. Just get that out in a second here, and in goes the 486 OverDrive. And yeah, it's gonna be
a little bit smaller, but that just means we'll
leave one row of pins all the way around the edge. Just match up the corner
there and that's that. And at this point it's
just gonna be a matter of figuring out those jumpers, and I'll be referring to
that list of jumper settings that you saw earlier
that I put up on screen, and yeah shouldn't be
too much to change though and I'll go ahead and get it booted up. Hey, it's booting. Nice. You hear that actual physical hard disk clicking on and whirring there. It has a little bit of
a click every so often, but I added it anyway 'cause
I was digging through storage. I'm like, oh man,
original old hard drives. Oh, 100 megahertz, 486 DX4, nice. So it has configured correctly it seems, so that's fun. You never know with
the jumpers. [chuckles] I double and triple check those. I actually tried a couple
of different configurations. One I tried earlier didn't work. So the the write-back version
DX4 configuration didn't work. Write-through did, and
here's what we got here. Write-back is enabled for the
L2 cache, the external cache. But yeah, I just put that
little hard drive in there just to test out really quick and see if I maybe wanted to, yeah, it's like 340-ish megs. I just wanted to see if it'd be fun to have an actual
physical hard drive again, just as a C drive, and then I'm keeping the
CompactFlash adapter here as like D just to copy a
bunch of things over easily and store some extra stuff, but run Windows and DOS and whatnot from a physical old spinny hard disk. Yeah, we're gonna run CHKCPU just to double, triple check here. So DX4, 100 megahertz, clock multiplier 3. Yeah, all good. Yeah, there it is. Enabled in Write-Through mode. Cool. Now let's run an actual benchmark. Let's do System Information, just to see how close it is
to the Pentium OverDrive. That's really close. That's a little closer
than I thought it'd be! Let me bring up what it was before, 'cause I tested this just
before swapping it out. Yeah, what? That's exactly the same rating,
at least in this benchmark. So the Pentium OverDrive
83 megahertz was 132.3, exactly the same as we're getting. So let's run TOPBENCH. Wow. Yeah, again, extremely close. Yeah, here's what the results were with the Pentium OverDrive. I was getting around 222 on average and this one is about 221 on average. Fascinating. Let's run the 3D bench. I don't remember what
graphics card I had in there when I did my Pentium OverDrive video, but I've got the Diamond
SpeedStar PRO in there right now. Okay, so we got 52.5. And here's what it was when I did the Pentium OverDrive, 55.7. So that's the result that I got when I originally put the
OverDrive in there, the Pentium. Huh. I do know that "Quake"
wouldn't run for some reason. Let's see if, okay. Huh, that's actually loading. Yeah, for some reason I was never able to get the "Quake"
timedemo to actually run on the Pentium OverDrive. Don't know why. This is doing it though. Hey, there we go! It's really dark, but
that's all right. [chuckles] It's actually running, which is better than the last machine, or the, you know, last CPU. Yeah, no, I never figured out
why I wouldn't run on that. So it's not running
great, but it is there. It's kind of cool to
see it all. [chuckles] It's not as bad as I
thought it'd be, honestly. It's just, you know, dark
'cause it's just using the default settings for this benchmark. We'll skip ahead here, see
what the average FPS was. Okay, we got 969 frames, 110.6 seconds. 8.8 FPS average, oh man. I was hoping we might get 10. [chuckles] We might have gotten double digits. But no. So okay, [laughs] well, yeah. It works, you know, but sure wouldn't want
to play it like this unless it was 1996 and that's all you had, and in that case this
would've been awesome. But, oof. This is my first time playing "Quake" on this machine I think. [laughs] I've just never
been able to run it. Oh, because like
originally I had like the, nah, I might've tried
it on the 66 megahertz like Am486 thing that I had on here, like when I first built
this like five years ago. But yeah, like I said, it just never ran at all
on the Pentium OverDrive, so that sucked. I'd be curious to see what
like an Am586 would do or like a Cyrix 5x86. Hmm. So many things to test all the time. This is miserable, and
the sound isn't even on. I don't even think we have, actually, do we have sound? No, don't even have sound enabled, but that's okay. So, let's try this really quick, just because I don't know what's on here. Processor Demonstration and
Diagnostics, version five. I guess install. There's also a setup. We'll do install. Looks like there might be
a Windows version as well. Okay. Yeah, interesting. Maybe we should run the Windows one, because yeah, I think I ran
the DOS diagnostics disk with the Pentium OverDrive. [computer chiming] Squiggly backgrounds. Neat, ODP_UTIL. Okay. Installed, let's see what it is. It's just this. Is it gonna run in DOS anyway? Yep, hah! All right. So whatever, it's just a
shortcut to a DOS program. Let's see one here, After Upgrade. Oh man, so it would've done a benchmark. Previously saved processor information has not been detected. Well dang it, now I wish I
had kept that one in there and done this beforehand. I didn't know that you could do that. Determining its speed and iCOMP index. Yeah, 435, whatever that, ah dang it! Ah, I wish I'd run this before, that would've been fun. Now I'll have to go in
there and swap it out. That's not a big deal, but then I have to put all
the jumpers back and it sucks. All right. So, [laughs] it's saying, according to this iCOMP index, that it's very close to the 63
megahertz Pentium OverDrive, but the 83 would be up there. I don't know if I believe
that on this system. But that could very well just be because this motherboard, man. This looks very much like the one that came with the Pentium OverDrive. Processor Instruction Test, there's this, which was also on the Pentiums. But, I mean, you know, yay, it failed. [laughs] It passed, it didn't fail. Floating Point Conformance Test. Yes, conform! Do that math! Do it all, fast, baby. Mm, faster. Ooh. So that's awesome. A successful upgrade in my opinion. Even though it's nominally slower than the Pentium OverDrive, but it's not so much
so that it's gonna make like any notable difference
whatsoever to my video. Is this just that I've
got a 486 in there now, which I am a little more fond of. And this pointless demo shortcut, what in the world. That's so dumb. Can't believe it was just a shortcut. I should have known seeing the
.pf file on the icon there. [computer chiming] [imitating computer chiming] Well that's pretty much it I guess. Seems I gotta do something else though. [logo booming]
Yeah. [energetic rock music]
Oh yeah, cool. I keep forgetting I've added that little wavetable
daughterboard [chuckles] to the sound card in there. [computer logos booming] [energetic rock music] - [Duke Nukem] Come get some! Damn, those alien bastards are gonna pay for shooting up my ride. [Clint laughing] - [Clint] Yeah, I remember
being around like 12 or 13 FPS on the top of this rooftop here. It's the same thing. So here is my thing, I'm
thinking aloud at the moment. That is, what is the
bottleneck in this system that is making it exactly the
same performance pretty much as the Pentium OverDrive? There should be a slight
difference, right? So here's all the things
I've swapped out on here. Like I've swapped out
the memory a while back. I put like faster, what I think is faster, 60 nanosecond EDO RAM in
here, 16 megs of that. That's pretty much what
I had in there before. But yeah, I was seeing if
it would make a difference. It made none. And yeah, I've swapped out the graphics, that obviously helps, but for like the CPU tests, that shouldn't affect those tests. Yeah. Is it just the motherboard itself is incapable of going
beyond a certain way? Like is it some bus speed things? Because I've looked all
through like, ah crap! [laughs] Settings on the BIOS
and all sorts of stuff. Again, I wasn't trying
to like blow myself away with a performance gain or something. Obviously I didn't expect
the 486 to be faster, but I did at least expect it to be slower or I expected that OverDrive to be faster whenever I initially did it. Yeah, if anybody has any things that they want me to look into or try or just check in the BIOS or whatever, I've gone through and set
everything that I know to do in terms of like memory
optimizations and stuff. So let's see here. Yeah, external cache enabled,
write-back, that's fine. Internal cache,
write-through is grayed out, and like I said, you can change it on the motherboard with a jumper, but whenever I do that
it just doesn't boot. And in terms of memory,
that's what I've got here. It's pretty much, you know,
I think that's good. [laughs] Whatever. This is definitely faster or, you know, the fastest I've gotten
things to go with the memory, but this is what I've got. I've messed with every single one of those options you've seen, and every single time it's
either like exactly the same, like this is as good as it gets, or it's so close that
it just doesn't matter. So, [laughs] at least
it's got a 4 86 in there. Again, that's literally all
that I wanted to accomplish with this video and I
think I've done that. Thanks for watching. Oh hey, nope, nope, nope. Wait, I'm not quite done
yet I guess. [chuckles] So a few days later here and I'm just still
screwing around with this because I find it
fascinating the discrepancy, or lack thereof between
the two processors. I've got my theories, but you know. Just kind of decided to look up some other folks' experiences with this and remembered Phil's Computer Lab. There's a video in his channel
where he did a comparison between the DX4-100 and the
Pentium OverDrive 83 megahertz. So yeah, this is what we side-graded from, the 83 megahertz Pentium OverDrive, and here is the DX4-100. I don't remember if he said
if it's an OverDrive or what, but yeah, you can see in
a lot of these benchmarks the results here are actually really close for things like "Doom" and
3D benchmark we were doing. But depending on some of the other ones, you might get more drastic differences. And like for instance,
System Information 8.0, he got exactly the same results on the two as well, just like I did. And with TOPBENCH, yeah, pretty close, with the DX4-100 being slightly faster than the Pentium OverDrive in that case, which is kind of how I got. Some of these others I didn't run, like the Landmark 6.0 FPU benchmark. That made a much more
significant difference, as you'd expect since that
was a really big difference between the Pentium and
the 486 class chips anyway. So I just ran the "Doom"
benchmark, max settings, and we got this right here. Let me see what it was when I did it on the Pentium OverDrive. Okay, yeah, so this is what it was in my Pentium OverDrive video. So of course the same game ticks, 'cause it's the same benchmark, and 2,418 reel ticks on this one versus 2,664 on the Pentium OverDrive. So there is a difference. It's still just not as
much as I thought. [laughs] I don't know, I always assumed
there'd be a wider gulf between the 486 DX4-100
OverDrive and the Pentium, and it's also just the fact
that the motherboard itself, it's not the best. You know, Phil even mentioned
that in his video there that I just showed some of the benchmarks. It's like, there's
slower 486 motherboards, and I know this one's slower. It always has been. Again, I wasn't trying to go
for crazy speed boosts here I was just curious what
the difference would be and I expected more of a difference. It's not a negative, it's
just interesting I think. So I've got a 486 in
the Woodgrain 486 again. That is entirely my goal. So yeah, I don't know what else to say, except I'm going to try
this Pentium OverDrive in probably that Quantex
486 that I got recently. Got it in the most recent
episode of LGR Thrifts. So that's cool, 'cause
that's a faster system. It's got a much nicer board for our 486 era thing going on there. It's one of the later PCI ones. It's got a Cyrix 486 equivalent type thing in there right now. It's endlessly fun with this stuff for me. And now I'm just rambling on about old processors and computers, but that's what I do. I don't know, I think
this is cool. [laughs] Let me know what you think. Thanks for watching this Blerb.
