No 4X AGP?

[BG]

Can't figure it out... I have the EPOX K7KXA mobo, ELSA Erazor X GeForce. (SDR ,flashed the new bios to the card too)My system is:

Win98SE
Athlon 700 (not oc'd)Voltage set to 1.7
256 SDRAM - PC133 (FSB set to 133mhz)
SBLve!
300W P.S.
Plenty of cooling (triple fan on CPU, Case fan and Blower fan)
Drivers are:
Nvidia v3.77


Whenever I set the AGP to 4X in the BIOS, all my games freeze. They will start and when I begin to play, I get a frozen computer with a great "screen shot" and looping sound. The only way I can reboot is with the RESET button!
When I have redo the BIOS to disable 4X AGP, it seems to stop. (although I haven't tried all my games yet, I tried system shock2 and it didn't freeze)

Any suggestions?

AGPaperture is set to 128
What is the AGP Driving Value? What should it be set to when not set to "AUTO" I have heard A8 for GeForce cards.

Played with different drivers but still seems to be the same with all.

AGP 4X Really requires RAM a lot faster than PC 133. RAMBUS RAM is your best bet. If you can shell out $800 for 128MB.

The problem could be cauesed by several issues. Are you suing the latest AGP drivers for your board. Stop by Epox's website and pick them up. Also, it might require a bios upgrade. For the comparative difference in speed between 2x and 4xs, there's is alomst none in games (<2-3%). The only time I can see an actual difference in in sythetic texturing benchmarks where the textures applies to the rendered scene or extremely large. I personally wouldn't worry about, unless it really bothers you.
