Upgrading the Woodgrain 486 PC by replacing the 66MHz 486 CPU with an Intel Pentium Overdrive! Taking a look at the box contents, the installation process, and some DOS game benchmarks. Pretty neat stuff being a drop-in upgrade for a Socket 2/3 486 motherboard.

  • The results of this upgrade have cemented my resolve to upgrade, like, everything else now haha. Next will probably be the VLB video card, but I'm also planning to try some different RAM, as well as a DX4-100 from Intel since I have one of those already. And if nothing else, I also have a much nicer 486 mobo ready to go :P

  • Makes sense that an 83 MHz Pentium in a 486 board would perform somewhere between a P-75 and a DX4-100 ;) But fun fact: The floating point conformance test was something Intel supplied for free after the faults with the first P5. I believe mostly to prove that they had indeed fixed the issue for the P54.

  • i buy and use one for time back then, it was verry deceyving result not for bug. but it was like some people who cant think and speack in the same time. i even switch my computer board for its, since it was not compatible whit the amd 486X4 limit to 66mhz in the bios despicte theyre was a pin setup for 25, 33, and 40mhz. so y switch the bord just for the intel CPU,... never work as espected, verry silent as noise go. i like that but slow, SLOW as melasse half of the time. never solve the problem its stop to think every minutes or so. no crash just like the computer stop what ever y do, take a segonde break! than resume what ever i was doing.... someone since then tell my that was the ecc in my 72 pin chip memorie that was incompatible? i never play games whit it y was working in adaptiong TINman a dos program for the blind trying to adapt it for windows 95 16 bits, a program i create wen working at Texas intrument in your corner of the planet, i help create a non APL version of the work sythesis a venture system betwen AT&T and texas instrument in voice synthese. Texas intrument voice synthese chip wheyre create whit APL library and register, i finish the years whit a 486X4 100 (push to 118mhz) since my new board was faster whit AMD its, a lots faster. after that years y switch to the pentium 60. they sell them a base price for the math bug, never ave problem whit the bug still a pentium board original P60 for 50$ i still ave it somewheyre in a molded resin box, i mold a lot of my old cpu in resin. not place to display them now... since i am renovationg. ok long renovation i start 5 years ago and still not finish. houps! i am retiry, we alwais a someting to do but slowly.

  • Personally, I have had a 486dx4-100 (also Amd). It had support for pci and 72 pin EDO Ram. If I do go down the memory lane and assemble something similar, I believe I will go with socket7 1st generation Pentium system, SE and MMX support will give me the best of both worlds. DOS/SVga games era, and Early windows 95/98.

I enjoyed the hell out of it. There was definitely a noticeable difference in performance. It was euphoric turning it on for the first time after the upgrade. I miss that wonderful machine.

  • I don't understand this. Back in 1995 Descent ran just fine on my intel 486 DX-2 66-based desktop PC (8 MB 70ns RAM - 2 x4 MB SIMMs). I got around 40 fps, very busy battle scenes, and that was at 1024x768, full "eye candy" graphics mode...even in multiplayer mode, over a 14.4K modem. ~40 fps, like it was on rails. I had a pretty nice 15" CTX CPS-1560 CRT digital glass monitor, @60Hz max refresh rate. Maybe the excellent performance was mostly due the system having onboard VLB video ("Vesa Local Bus"). The chipset was Cirrus Logic CL-GD5428, and it had 1 MB dedicated VRAM. When I upgraded from the DX-2 66 to the AMD 5x86-133 MHz CPU, the fps jumped up to 60 fps (which is all that my 60Hz CTX CRT monitor could handle). Good times. Jeez, I miss the "Go-Go '90s" so bad...lots of LAN parties & hot BBS babes.

  • Back in 1999 I was working for a local PC repair shop, I used to build mostly Athlon/Duron systems at that time but also quite a lot of upgrading old systems with these overdrive processors, I remember there being loads of them, they came in a variety of speeds for a multitude of sockets...and they were not a cheap upgrade if I remember correctly

I emulated an Pentium OverDrive with 128 MB of ram and a 30 gb hard disk and installed Windows XP Pro on it. It was very slow. Edit:For Windows XP to even install the motherboard needs to be upgraded to a ASUS P/I-P55T2P4

  • Back in 1996 my intel 486 DX-2 66 MHz -based system with onboard VLB 1MB Cirrus Logic GL-CD5428 video ran Duke Nuke'Em 3D at 1024x768x256 at 72 fps on rails. Smooth, fluid gameplay throughout the game, locked in at 72 fps. The game literally shimmered and sparkled on the excellent CTX CPS-1550 15" CRT glass monitor (ViewSonic clone). FPS would drop to 60 fps at VESA modes 800x600x65K colors, or 640x480x16 million TrueColor modes. Same results when I upgraded to the AMD 5x86-133 MHz CPU (WT mode only L1 cache mode only, no write back), so the Cirrus Logic VLB 5428 chip was the bottleneck (but still a barn burner). The AMD 5x86 CPU really did give this system Pentium 75-like performance (except for floating point). The core of the system was the Reply Corporation (Cupertino, CA) Turbo system board (upgrade of original IBM PS/2 30-286 Model E31 - intel 80286-10MHz, running @ 1 wait state).

  • I dunno man, Duke 3D ran great on our 486 DX4 @ 100 MHz. It's basically running a suped up version of the Doom engine... Descent also ran fine... We did have a VESA Local Bus onboard graphics though (the PC was an Acer, and it advertised as having VLB even though it was on board). Quake came out after we upgraded to a real pentium though, so I can't speak to that.

  • you can actually run the quake benchmark on a dx2-66, you just have to do it manually by going into c:\dosbench\marks\quakes\ and running "quake +timedemo demo1 +exec mode12.cfg -nosound - nocdaudio". Im not sure why that menu item (or more specifically the batch file meant to run that quake benchmark) causes that error, but doing it manually should work. Most dx-2's dont go above about 6fps though, so it would be interesting to see what the overdrive does..

  • Those benchmarks are surprising. Even in write-thru mode with 16K L1 cache, the Pentium Overdrive 83 should be 60-70% faster than than DX2-66. There must be some other bottleneck with that board... The storage is CompactFlash, so that should be plenty fast, but maybe the IDE controller card is very slow? Maybe the AMD 5x86-133 will perform significantly better with this board because it's just a regular 486 clocked very high, so you won't be bottlenecked by the slower memory bus.

That game really needed a real Pentium, fortunately it ran beautifully on the Pentium 166 machine that replaced the 486.
