Hitting the Wall

[DLzone]

I just recently bought an Asus P4P800 to go along with my 2.4b. I threw in the new board and tried to see what my processor was capable of. First try I hit a completely stable 3.06 ghz (167 FSB) with my memmory timings maxed out. CPU temps were great: Idle 20C Full load 30C. Yet whenever I try pushing it further then 169 FSB the monitor does not display anything, I can hear it go through the boot process, but I don't get anything on the monitor. I tried backing down the memmory timings, and increasing the voltage, but have still had no luck. My only guess is that perhaps the Geforce 3 Ti 200 is at fault but still this doesn't make much sense because the Asus has frequency locks to keep it in check. I will know for sure as my replacement Radeon 9800 will arrive tomorrow (my original crapped on me day before). Still, I can't figure out what is holding me back. If anyone has any insight please let me know. Here are my full system specs.

P4 2.4B (Bios: 1010)
Asus P4P800
2 x 256 Corsair Cas 2 DDr 400
Geforce 3 Ti 200 (Being replaced by Radeon 9800
Sound Blaster Audigy
Maxtor 80
WD 60

Try actually manually setting the agp to 68mhz to 70mhz and see if that helps....

Also up the vagp to 1.6-1.65v and the vdimm should be at 2.75-2.85v...

Ok, I tried what you said. Unfortunatley the bios I have only lets you adjust the AGP voltage from 1.6-1.7. I put the voltage at 1.7 (was 1.6) and vdimm at 2.85 (was 2.75). Also the bios only lets you select between 3 diferent frequency locks I chose the higher 77.33 I think. After doing all this I was able to reach 171FSB = 3.078 ghz. But soon after the monitor would either go dark or I would get corruption. 🙁 I'm going to upgrade to the newest bios and see if that helps.

try relaxing your mem timings & grab the Latest bios.
