Opteron 170 OC question

So my Opty hit a brick wall at 2.7GHZ 1.47v on the overclock.

2.8GHZ and even 2.75GHZ on 1.52v refuses to Prime for more than 30 seconds on Core 0.

This is with the memry timings loosened to 3-4-4-8.

Is there any chance that using my memory divider is causing the OC to be unstable. I know its a pretty big reach, but anything helps.

I tried to get a buddy of mine to bring over a stick of PC4800 to see if I can get higher than 2.7GHZ with the RAM running 1:1, but he didnt answer my call.

What do u guys think? Worth the hassle of throwing in new RAM or am I jsut stuck?

Thanks.
 
Try 183 MHz divider, and if it's not prime stable, it must be your cpu, or your memory was overclocked too high in the first place.
 
Drop the divider down to 133/100 and then run it. Just take the ram right out of the equation. Its probably the cpu though.
 
The RAM is running at DDR 400 so I am positive that its not the RAM.

My real question was is the usage of a memory divider AT ALL causing instability? Compared to no divider.

Again, I'm talking about the divider itself, not the RAM speed I am running
