I'm currently overclocking my Opteron 144, I've had it clocked at 2.4GHz for about a year and am now trying to see how far it will really go-right now I have it clocked @ 2.5GHz, 277x9, with 1.425V voltage in the BIOS and apparently 1.4V~ according to cpu-z.
Obviously I want to monitor my temperatures to make sure I'm alright, especially since I did a slight increase in voltage. When I initially oc'd my system I used MBM5 with the nforce-4 profile (from dfi street) and this worked fine as far as I knew. Now that I'm trying to oc again, I downloaded Core Temp, and am getting much higher temps than with other sources:
@ 2.5GHz, 1.4v
Core Temp: 50-51C~
nvMonitor, MBM5: 40-45C~
(under load)
Most on the Internet seem to think around 50C is OK for an A64, and AMD says that 65C is maximum for the Opterons. I'd like to know which of these temp programs are accurate, and which I should compare against the AMD maximums/ other people's temps.
Thanks. If anyone wants to know my cooler is an ACF-64 Pro.
*As a side question, I'm also wondering why certain RAM dividers on my DFI Ultra-D are not stable. The 133 and 140 dividers are not stable, even though the 150 is.... this had led me to believe my CPU could not clock higher than 2.4, yet now I have tried 120 and it worked fine. Why are 140/133 unstable when my memory would still be clocked under 400MHz effective?
