Recommended Posts

Well i've tried alot of different things and basically my problem is my opteron 144 cab1e wont pass prime. It passed All 3dmarks, AM3, pi 32M, etc etc. The settings im trying are :

 

- 334 x 9 (3 x HTT) vcore 1.52V. Ram at 166 (280mhz) 3-4-4-8 memtest error free. This setting passes everything except prime.

 

- 311 x 9 (3 x HTT) passes prime. ram 180 (5/6?)

 

- 334 x 4 (3 X HTT) fails prime/ ram 166

 

- 334 x 4 (1 X HTT) passes prime./ ram 166

 

-334 x 4 (2.5 X HTT) fails.

 

My settings are as follows:

The only reason they're working on auto is because the rest of the secondary timings are set so loose. If you ever get to the point that you want to optimize your system and get the most out of it at the lowest possible voltages you will be manually setting those values. But I guess all that matters is the big 3.0. Not how you get there.

yeah well. TBH, I have no idea where to start with the DDS and DDDS. I tested a few settings and windows wouldnt boot. I will eventually tweak it but im already scoring big in all benches. Dont forget the ram is running at 270mhz so tightening anything might not be possible.

My mistake. CPU-Z sure looks like it says 250.5 for the memory in the screenshot. I guess I can't see it clearly.
