I wouldn’t overdo with the expensive sleeves. Wrapping the existing cables, or replacing them with affordable option from Corsair, will be more than enough.

Since you are going hard after aesthetics, figured i can point to 2 things that caught my eyes: 1. The CPU fans have these naked cables that may benefit from a black woven sock. 2. The GPU power cables look much cheaper than the rest of the components. To a less extent this applies to MB and CPU …

Good link. Thanks. Brings few extra bits of clarity to my understanding. Yet, Coppers work fine on this board, just not in 133MHz FSB config. Very strange.

The video i shared shows the PC working again. It looks like now you can run the video card properly, but have problems with the LAN card. Can this be a prickly LAN card that does not click with the mobo (or the other way around) ?

PVI versioning came up before in another thread, that i cannot find at this time. Version ID is not a fraction. It is usually composed by major.minor numbers which are independent from each other. Both boards are major version 1. The one here is minor version 22, yours is version 8. Your explanation …

Remembered what was it. Notice the first 3 parameters in the PCI AND PNP SETUP in BIOS. video Ran a basic offline graphics test. The program often crashes on exit - this is not related to the story here. It is intended to run on WinNT. Can work on Win95 as well, but glitches quite a bit.

The PVI rig is supposed to be my favorite sweet-memories PC. This implies prefect condition, but its health deteriorated since the last inspection. Win95 is not fully stable - frequent Kernel panics with apps shutting down. Will have to spend some time on it over the weekend before answer any …

Your explanation brings some memories. Set CACHE WRITE CYCLE to 3. You may want to set DRAM WRITE CYCLE POST to 1. See if that fixes it.

These glasses are still on their way ... A while ago, buried somewhere in the depths of this thread, we had a conversation with CoffeeOne about VLI/PVI where we figured out the purpose of the JP16/JP18, respectively. Until then i was not able to get run Am5x86 processors at 180/200MHz on these …

Extending a request for ATronics 2015PL cross-check, if somebody has controller based on this chip and is willing to spend some time on it. The late DOS driver (version 3.27 06/08/95) offers control parameters, but seem to be problematic in general. Performance is really bad. ~0.35Mb/s according to …
