Basically the default RAM timings were off and it was messing with my OC, once I took care of the timings it sorted itself out :)

Hey guys, I've got my Opteron 165 up to a happy 2.5 GHz with 1.38V, But I've had to run a 5/6 divider, I also had a nice 2.38 at 1:1. So my options are:

1)

9X278= 2504
5/6 divider so the RAM is functioning at 231

My other optoin is

2)

9X265= 2385
1:1 so the RAM is functioning at 260

What option would you guys pick?

Looks like the difference is 120MHZ CPU at the price of lower functioning RAM.

think the concensus would be max CPU... and try to tighten up RAM timings....

but i'm not exactly an OC PRO

which of the timings should I loosen?

The timings are:

CAS: 3
RAS to CAS Delay: 3
RAS Precharge: 3
Cycle Time: 7
Bank Cycle Time 7

IF you HAD to choose the two options I mentioned, which would you choose?

Thanks!

EDIT: It apears stable at 282 with the 5:6 divider as well (passed Prime 95 for an houer). However, it completely fails at 285 though.
