  • ["All the Good Things" by Nocturnal Spirits plays]

  • Greetings and welcome to a LGR Woodgrain 486 upgrade thing!

  • And today, we've got the Intel Pentium Overdrive Processor.

  • "Makes your Intel 486 Processor-based PCs run faster."

  • Which is great, 'cause that's what I wanna do!

  • Yeah, we're gonna take the Woodgrain 486's AMD Am486 CPU

  • that's in there, running at 66 megahertz

  • and turn it into a Pentium, of sorts.

  • It's kind of a weird thing, you know,

  • it takes a 486 and makes it an 83 megahertz Pentium.

  • Yeah, bit of an odd frequency rating there,

  • but that's what Intel was doing, man.

  • In the mid-90s they had all sorts

  • of interesting Overdrive chips.

  • And this one in particular just attracted me to it.

  • Yeah the PODP5V83,

  • [chuckles] you know 'cause of the weird rating 83 megahertz.

  • And I've just never messed with one of these

  • Pentium Overdrives before,

  • just 486 Overdrives that take like a 486, 33

  • and turn it into a DX4-100 or whatever.

  • And perhaps that would be more suitable

  • for the Woodgrain 486, but I've got this one here,

  • complete in-box,

  • it's been sitting in its sealed packaging for 25 years

  • thereabouts.

  • It was originally launched in October 1995,

  • maybe early 1996, depending on where you look.

  • But, back then it was $299 US dollars

  • for just this upgrade chip,

  • and that's the equivalent of around $500

  • adjusted for inflation,

  • so a bit pricey for just a CPU upgrade

  • to the point where they didn't last on the market

  • for too very long.

  • And there were a log critiques in the media

  • about it being just being like,

  • who the heck is this thing for?

  • Average consumers found it too costly

  • and businesses would rather just get a new system.

  • One IT guy was quoted as saying,

  • "both a memory and hard disc upgrade made sense

  • "alongside a Pentium,

  • "so if you do one, you have to all three.

  • "And if you end up doing all three,

  • "it's just cheaper to buy a new system."

  • So, yeah I mean, all good points,

  • I totally give all the points to their logic. [laughing]

  • But man, Intel was pushing all the things it could do,

  • I mean look at all these software benchmarks, you know.

  • 135%, 144%, 267% better in some programs,

  • oh wow.

  • Need help in selecting which one you need?

  • I mean, look at all these things

  • that you can do on the website.

  • And yeah they had a website,

  • you could go out on the web,

  • the cyber spaces and you could go and download this PDF,

  • seriously, I did, it's still on archive.org.

  • Yeah, the Intel Pentium Overdrive Processor

  • performance report.

  • It's 30 pages of like, just benchmarks

  • and how cool it is to use this thing in your 486

  • and there's so much going on man.

  • I don't know, I don't really, I don't know man.

  • I just wanna play Duke Nukem 3D

  • and Descent II and stuff.

  • But,

  • there were a lot of serious people look at this

  • and making paperwork. [laughing]

  • Anyway, let's go ahead and get this unboxed

  • because I'm curious what's inside.

  • [smooth jazz]

  • Oh, the box itself is glued to itself.

  • Actually looks like this one was made in 1998.

  • February 13th, wow that's almost exactly 22 years ago

  • on the day I'm recording this.

  • Okay, maybe they were on the market

  • a little bit longer than I've read.

  • I read they lasted through 1997,

  • '98 would have been pretty late

  • to get an 83 megahertz Pentium.

  • [laughing] They did not make that easy.

  • Ooh, fresh Pentium Overdrive.

  • No Bachman Turner included.

  • Look at that.

  • Yeah this was one of those,

  • I believe, the heatsink is permanently attached

  • and there is a replaceable fan clipped to the top,

  • but, yeah they were serious about the cooling on this thing.

  • Just as an example,

  • my AMD486 that's in there right now

  • does not require any cooling at all,

  • it's a 3.3 volt CPU,

  • so it's never had a heatsink or fan or anything.

  • But this, yeah they're like "it's 5 volt,"

  • "it runs hot or whatever"

  • "you just gotta make sure it's nice and cool."

  • Gotta wonder about the thermals

  • in between the CPU and the heatsink, but we'll see.

  • Let's see here,

  • wonder what we got, oh man.

  • So we got a Stay In The Loop registration card,

  • the beginning of a valuable relationship with Intel.

  • Just what I've been looking for around Valentines day.

  • And we have the, wow this is not something I was expecting.

  • "Overdrive Processor Demonstration and Diagnostics."

  • Okay.

  • We've got a little remover tool of some kind.

  • Intriguing.

  • And some paperwork.

  • "Attention, Packard Bell systems,"

  • oh dear, what now.

  • "Serial numbers 450 and 470 require additional hardware."

  • Okay, we're not putting it in any of those.

  • Yeah quick installation.

  • I mean, yeah, pretty simple.

  • Pretty pretty simple.

  • It's just a drop-in thing, man.

  • Got some jumpers if we need,

  • I guess a diagnostics disk to check things out,

  • that's cool, I'm glad it comes with that.

  • Lets see if the manual says what to do with this doohickey.

  • Oh, there's an animated demo, that's gonna be good.

  • Ha ha, I like animated demos.

  • Okay, so that's what that's for,

  • removing the processors from the socket with no handle,

  • haven't seen one of those in a while.

  • Not in a 486 anyway.

  • So yeah, ah yeah, that makes sense.

  • You got the little groves there,

  • fits between the pins.

  • Dang that's cool,

  • glad I have one of these,

  • I've had some trouble pulling things out

  • of like a 386 before. [laughing]

  • so, yeah anyway, the rest of this just seems

  • to be generic.

  • Ah, we've got a datasheet, how nice.

  • Although I already looked up all this stuff online,

  • but yeah, check it out, man.

  • This is something I'm pretty excited about,

  • 16K of code cache,

  • and 16K of write back capable data cache.

  • The AMD that I have in there right now

  • is only 8k of L1 cache.

  • Still no L2 on board,

  • that is on the system board itself.

  • I have 256k of L2 on that motherboard

  • that we upgraded to in the past

  • because didn't have any L2 when we first did the build.

  • But, yeah, this should be quite the lovely thing.

  • Ha, that is fresh.

  • Look at this thing.

  • That's just so clean, so nice.

  • And check out that integrated fan,

  • heatsink cooler design, man, it is all clipped on there.

  • Looks like the fan could come off,

  • but I mean that heatsink is pretty thoroughly attached.

  • And I like the fact that it looks like

  • it gets the power straight through the pins.

  • There's no connector for a fan to the motherboard

  • or Molex or anything like that.

  • This is exciting man,

  • ah dude, it's not gonna be a 486 anymore,

  • it's gonna be the LGR Woodgrain Pentium,

  • that's weird, oh I don't know if I like that,

  • I didn't think about that. [laughing]

  • Well, anyway,

  • this seems like a pretty clear upgrade on paper.

  • Will it be 100+ percent better like Intel claimed?

  • There's only one way to find out,

  • that is get this thing set up

  • and try out some benchmarks and games and stuff.

  • Alrighty.

  • Let's just get the old AMD one out of there.
