Do you find this odd?

[gplracer]

I have the computer below in my specs. It is prime stable. I just got an opteron 170 0610 and it overclocks to the same speed? Do you find it odd that I get the same speed out of it? I wonder if there is something that could possibly be holding me back. I can go higher but prime errors after about 5 mins. This is the same as my single core opteron. Thanks!!!

sounds ram related...

 

usually a good indication of 2 cpu's hitting a wall at the same spot...

I have tried the ram at a lower divider but i get the same result. Maybe it is another setting. I am running the vcore at 1.475 on this dual core and it is prime stable. Only the first day of testing though. I have the ram at 2.70v. The only difference that I see is that my dual core chip needs 1.457 and the single core needed 1.45. After 12 hours of prime 95 the core temp was 43-44C. Idle temp is around 33-34C. Is there something else stability wise that could be holding me back?

An Opty 170 at 2.91ghz on air, and your wondering why it won't go higher :drool: That is a very good clock in it's own right and on a nice vcore as well. To the point though, getting higher will take a lot more patience and effort. As has been said, it is in all probabilty ram related. Also as you have maybe found out, not all the dividers will play ball on the 170. To be able to help constructivly though, you need to post up a list of your settings. Use the OCDB template, then post it up.

Here are the settings that I am using

306x11=3366MHz

are u serious???

 

edit: ohh.. must be a typo.. ur 170 only has a multi of 10

Yea. To get 263 on the ram(306HT) that'd be 9.5, not 11.

[gplracer]

Sorry my fault that was a typo.

[Brother Esau]

You should not use half mutipiers

[gplracer]

I tried 300x10 and even put the ram at 5/6. I had to raise the vcore to 1.5v and then it booted fine but prime 95 failed in less than a minute. I am reinstalling windows now just in case. I had some sort of mpeg audio issue anyway that would shut down my tv tuner when i tried to record something.

[dr_bowtie]

timings seem plenty loose...and on par so far...you may need 1.55 to get where you want...these things seem to scale well up to 2.8 on stock vcore then then from there it climbs pretty fast..

 

I could get 285x10 on 1.35 easy but to get that extra 15 took 1.5...then another .02 to get 310x10...thats pretty much +.2

[Guest nova]

Here are some of my settings (that got me to 3.0) My rig seems to like these CPU VID values much better that the setting you are using. May be worth a try???
