Nice little 3DMark2001se problem

[=STE=BloodAngel]

When I clock my cpu to 2.7Ghz, Pifast and Sisoft Burnin 20 loops stable, memtest also stable @270Mhz. I've set the Vagp already 0.1V higher than normal, so 1.6V now.
At the end of Lobby Low I get a CTD? Any idea whats causing this? I've already tried upping the chipset voltage and reducing the LDT from 4 to 3.
Does Vagp 1.7 kill the card?

Plz help me out here.

Some further testing, using a divider for the memory solves the problem but kills my bandwith. Really weird and all because Memtest really doesn't give any errors.

Any ideas for running 2.7Ghz with mem around 260Mhz using multipliers and/or dividers.

There should be no problem with pushing the AGP V to 1.7V but my friends having X800 say that the cards dont like when they put it higher from 1.5V. Did U try it just with 1.5V?

Vagp 1.7V didn't help either, my guess is that its the memory. I tried Vdimm up to 3.2V but it wouldn't help.

And on 1.5V AGP it the same?

Yes , it just won't work 1:1 no matter what I throw at it.

3.4V???

Tried going down like 5Mhz FSB???

2.65Ghz 1:1 is stable, but 2.7 sounds cooler

im PRETTY sure that lobby's are harsh on the memory... dry reducing your latencies. or simply go 265 1:1 lol.

WTF is CTD?
Crash to desktop??
If so, it's 100% your RAM. Try to slack timings or raise your Vdimm .

Do you have a fan blowing over your RAM?
I've heard it helps stability quite a bit with this EB RAM.

Btw, be carefull with AGP voltage, it might lead to card deaths.

i don't think so..

i know Hipro5 ran multiple vidcards at 1,9V for some time,
and they all lived
But to be sure i wouldn't try higher than 1,7V for a long time if you don't know what will happen
