***Stumped***

Maybe someone can tell me what the **** going on here.

OK, I have a 600e OC'd to 866 (144 FSB @ 1.85v) BX chipset @ 3.6v, Geforce DDR @ 150/340, sidebanding on, apature @ 64 STABLE as can be. I've run CPU stability test overnight, CPU-burn, Quake 3, 3d-mark-2k, & the kitchen sink @ this mofo & can't get it to crash.

Now, if I bump it up to 900, everything goes out the window. Crash, crash, CRASH. I've set the apature to 4, underclocked my geforce, pushed the CPU voltage as high as it will go, turned off sidbanding, ran AGP 1x, set the memory to 3-3-3, and I went crazy with heatsink/fan solutions. The CPU/vid/bx/chassis now run between 30-35 C on average under full loads.

Guess what finnally worked????! I ripped out my geforce drivers & ran the windoze default pci driver. **nasty** Stable again!

So what gives? It almost feels like when I had my old Athlon Irongate rig & was trying to set the AGP mode to 2x & I just couldn't, no matter what I did. This was of course an AGP voltage problem.

SOOO... I have concluded that either my AGP slot is getting it's voltage cut @ a 150 FSB, OR... the CPU is just not strong enough to work with my vid at that speed.

any thoughts???

system:
mainboard-MSI 6163 pro rev2
CPU- 600e on MSI Master Slocket/alpha pep66
Memory- 128mb Mosel Vitalic 7ns (good up to 150 @cas2)
vid- CL Geforce DDR
Power Supply- Antec 303
Sound- CL Sound blaster live
CDROM- HP 8250 Writer/Acer 50X
Network- Cisco 605 DSL

Thanks

ya i doubt your vid card can handle that high of a FSB, thats where i think the problem is

oh and you might be able to keep that speed if you had 256 megs of ram instead of 128, would be easier on both your CPU and vid card
