Looks like any 3D accelerated testing will have to wait for a while. Voodoo 3 driver doesn't like 486 CPU for some reason. Initially, I did Windows tests with S3 Virge, which was more or less stable with 60Mhz. EDIT: Ok, the Quadro 4 NVS booted up with the driver installed. It's also 60Mhz capable, …

I have an AMD chip which can run DOS benchmarks at 180 MHz and 4 V but fails in Windows. Technically it can run DOS benchmarks on 3.45V and can boot into Windows, but I've increased it to 4V, just to be safe. I have found that running GLQuake in loop for an hour can be helpful Might as well just …

Is it safe to run the PCI bus at 60 MHz with a Voodoo3 PCI card? Yes, Voodoo cards are 66Mhz-friendly. Their AGP variants are just glorified PCI 66Mhz cards too. With this configuration, are you able to run other PCI cards? Unknown. But some LAN and IDE/SCSI controlers will work, especially if it's …

That is good news. Unless of course you were mistaken with the frequency. No, I did some tests with aforementioned Trident card just to be sure. LUCKYSTAR LS-486E SETTINGS.png SpeedSys test is showing me ~4800Kb/s video memory bandwidth on the 8900D, while the default settings (PCI 33Mhz, 1/4 …

That's arguable, but I think all high end boards for 386DX are from "486 local bus" era.

Trident 8900D video card tolerated it quite well, with performance boost around 75%. Some late ISA sound cards like Yamaha YMF719 or Avance Logic ALS100+ probably can work at 20Mhz too.

Compared to ARKLogic, Chips&Technologies, Tseng and late S3 - yes, the card is sh*tty. Even Trident 9440AGi is faster.

After VERY thorough cleaning I have finally managed to get stable L2 cache with 0 WS and 22.77 points in SpeedSys. It didn't helped with the Socket 2 though, so most likely it will require resoldering or replacement. Perhaps it's fixable by removing the upper part of the socket, but I have some …

How would I know? Judging from late production date, the wire mod won't do anything or could harm it.

B revision. Production date: November 1994. PCB doesn't have factory added wire. I am not aware of BIOS revisions to this board. Not sure how to force multipliers or 20Mhz. Anyway, for now the board is drying up after water session. Maybe it will fix the problem with the Socket 2. Or it will die …

Interesting note: The adapter is capable to work at 20Mhz ISA bus speed, i.e. very overlocking friendly.

Ok, this board is just cursed. After installing some CPUs into the Socket 2, it refused to boot. Apparently some socket pins just broke or bent after few installations. Performance of the integrated 486BL is also very low. SpeedSys reported only 8.56 points, which is roughly on par with 486DX 25Mhz. …

After rechecking everything, I've noticed that my board was missing one jumper. Without that jumper the cache is very unstable. Right now I can push the original cache to 0/1 WS (Read/Write). EDIT: No, it's still not stable, but at least that's a progress. EDIT2: Another batch of perfectly working …

My recommendation would be FX-3000 board. 256Kb cache, good performance, oscillator is not soldered and CPU can be switched to 486.
