This sounds like typical Kyro II AGP2.0 weirdness. The chip identifies as AGP 2.0 compatible but 4x is deactivated and since the AGP 2.0 indicator pin isn't wired to ground some boards assume a wrongly keyed card and refuse to work as a safety measure. Now I assume 'hotplugging' the card forced 4x …

Looking at the card I believe it's quite possible it'll only work with PPGA Celerons, not FCPGA Coppermines. Socket 370 was changed slightly for Coppermine and with many slockets you'll need a jumper to configure them for either.

I believe this is a common issue and related to suboptimal PCB layout. I have Voodoo Graphics boards that run fine at any speed and others that crash instantly with FSb>66MHz and CPUs>333MHz.

A fairly common one is the P200 in the ceramic package. Every single one is fake. They only made them as PPGA, not CPGA. Would this apply to P200MMX too? I have one in Ceramic SL2RY is the real deal. I had (have?) one and it was the right colour all the way through, didn't scratch easily and …

look at the speedsys shots OP posted. though, since he did mention using the same settings, it could have also been a misdetection by that tool? I think we both got it wrong. OP says his Tillamook runs at a max multiplier of 4x. That means he ran his CPU at 4x 112MHz fsb as well and the MMX …

What am I missing? With L2 enabled, K6-2 and Tillamook perform virtually identically (76 vs 77 fps), while the K6-3 sails past both at 83 fps. the AMD chips ran at 112mhz FSB here versus 100mhz for the tillamook. I can't find that info, can you point it out? Also why run the CPU at that fsb when it …

As far as I know batteries differ greatly depending on their chemical composition and will react badly to wrong loading currents. This may range from not accepting any charge at all over early failure to leaking or exploding. Depending on the loading circuitry it may be fine but it may also overheat …

Keep in mind the selection of games used in that performance scaling project. There's a discussion on low performance in Half Life with weaker CPUs here where a member has a Voodoo3 2000 PCI (performs very similar to V2 12MB in SLI) and experiences regular drops below 20fps with his K6-III+@600MHz. …

I have recently performed an ISA slot upgrade on my two GA-7VX motherboards as well. It works with no issues. It appears there's a full featured retail version of the board as well as an OEM version that lacks the dual BIOS feature (luckily) as well as the onboard Creative chip and ISA connector. …

Thanks! Very helpful. I had not noticed how bad that corrosion was. Will do as you suggest. (Or try to! I've not done any major rework before, though a bit of cleaning, soldering and continuity testing is within my abilities.) Perhaps that will fix the seemingly keyboard-related stability problems. …
