Dragoran Posted February 8, 2006 Posted February 8, 2006 hello I have a opteron 170 on the dfi nf4 expert and it can't go to 2.8 not even with vcore 1.63V temps are max 45-48 (when using vcore > 1.6) Ram is G.SKILL 2GB HX running at 225Mhz (230 MHz if I try 2.8) What can be causing this? now it runs at 2.7 @ 1.46V It can boot @3Ghz ... but why does it fail dual prime @ 2.8 ?

Smoken Joe Posted February 8, 2006 Posted February 8, 2006 The limits of the CPU perhaps when people report they are stable at 2.7 2.8 or whatever they often dont bother testing with prime if it doesnt immedatly crash they claim it is stable even though the OS etc are getting borked. You might try to get the temps lower check the TIM or if you like to take risks remove the IHS. What cooler do you have?

Guest FZ1 Posted February 8, 2006 Posted February 8, 2006 What stepping? The 170's that do 2.8+ are the exceptions, not the rule. Quote Share this post Link to post Share on other sites More sharing options...

ludeboy12 Posted February 9, 2006 Posted February 9, 2006 opterons are hit or miss.....there have been other duds w/ the 0550 UPMW stepping.... Quote Share this post Link to post Share on other sites More sharing options...
Voltes-5 Posted February 9, 2006 Posted February 9, 2006 opterons are hit or miss.....there have been other duds w/ the 0550 UPMW stepping.... Very true, from what I have seen in the Opty threads and with the 165 0546 and the 0551 I have, the older one got up to 2835 with 1.66 vcore then I tried the same settings with the 0551 but its not stable. I could only get it stable at 2750 with the same setting. Quote Share this post Link to post Share on other sites More sharing options...
