Currently in France on vacation, so will run the Quake 3 demo benchmark and post the results here when I get back.

FYI

I upgraded my K6 machine:

K6-2/350MHz
Quake 3 Demo - 3DFX Mode - 640x480 (with default graphics settings). 22.5FPS.

K6-3/400MHz
Quake 3 Demo - 3DFX Mode - 640x480 (with default graphics settings). 35FPS.

Much quicker than I thought it would be.

My result (same settings as yours) - 19.4 FPS. This seems to be expected as my AMD is running at 66mhz bus.

Sorry to bring up an old thread. How much ram were you using in your machine? Can you try with just 64mb? I suspect your motherboard cannot cache anything over 64mb, slowing things down.

Where did you got those upgrades?
I've been looking everywhere to no avail!

Amazon has one, but they don't ship to my country 🙁

Would anybody be so kind as to elaborate on this subject?

Could this be done to a PC Chips M577 mobo with VIA MVP3 chipset? Manual says jumpering for 100 FSB max.

The multiplier selection is decided by the CPU, not by the motherboard, so you can do this mod on any motherboard you want. It just requires the right tools (inexpensive) and a little patience. I forget exactly how I went about this, but I believe I consulted with a datasheet for an AMD K6 CPU. Other's have done this mod as well, and it is documented online.

Sure, can give it a try, but why do you suspect it can only cache 64mb? Using 80mb at the moment. If you compare the benchmark in Q3 of a 350mhz K6-2 running at 100mhz bus and mine 400mhz k6-2 running at 66mhz, that should explain why I am 3 frames pr. second below.

I found it on Ebay 6months ago.

Got any link? I can't find any online documentation, other than the AMD K6-2 Desktop Datasheet.

I think I used this:

Thanks!
