The main problems when overclocking PCI are the hard disks plugged to the usual PCI IDE controller. Typical issues are data errors.That may not be obvious on first glance since the error correction with higher UDMA modes does its job, but the transfer rate will drop considerably. For some HDD the …

You get improved benchmark scores running at 40mhz? Are you asking me? For heavily graphic applications, yes there is improvement, however reduced cache and memory timings for all but 256K double-banked cache sorta negate this improvement. I am doing some benchtop "research" in attempt to get to …

I've been playing around with the 40 MHz setting on some PCI 486 boards. My S3 Virge DX 4MB card will flicker from time to time after 10 minutes of uptime. The GPU also feels pretty warm for this card. Diamond Voodoo Banshee 16 MB doesn't seem to have any of the above mentioned issues, but I am just …

I checked all the wayback captures for gemlight and it seems v2.05 was the latest BIOS.

Unfortunately, that v2.22 BIOS is not for the PKM-0033S or GMB-486SPS. It is for a DTK PAM-0054, which is for a 430FX board. The reason I want the BIOS update is because I recall the Zita Tomato 4DPS board, which is also SiS 496/497-based, would not recognise 64 MB FPM sticks until I updated that …

I tried looking for both, but stuck out. I've had better luck with forum users sharing these long lost BIOS updates. It is also possible that a BIOS update was never released. Anyone with a DTK PKM-0033S or Gemlight GMB-486SPS have either the original BIOS or some update? Thanks a lot!

Does anybody have an updated BIOS for the DTK PKM-0033S E-0? The BIOS I have is from 12/11/95 with the following revision string: DTK PKM 0033S.P02.02.05-V2.05 Anyone have any first-hand experience with this board?

To test bad caps which look OK, you need to remove them from the motherboard. Usually start with a capacitance meter, if the capacitance of the capacitor is out of its rated tolerance (usually +-20%), the cap is bad. If the capacitance is within its tolerance, you need to use some kind of ESR …

Bad caps or faulty northbridge? Even caps which aren't bulging could be faulty in a system of this era.

With '256' and '257' cache, you can set the TAG as 8+0, or 7+1 in the BIOS, where the +1 is the dirty bit. Usually, you run 7+1 for write-back cache and 8+0 for write-through cache. Does the '257' pieces handle this dirty bit any differently than the '256' pieces?
