Phenom ii 955 C2 24 hour prime95 stable overclocks? - Page 2

post #11 of 12

What was your voltage? What about CPU-nB clock and volts? Any other volts changed, ie chipset or RAM?

okay i believe 3.6 ghz 24 stable on phenom 955. my problem was my IMC is weird on my chip. Not exactly sure yet, but just discovered that downclocking my RAM from 1333mhz (stock, even overvolted though, i proved them at 1348@cl7 1.616v 2 years ago though) to 1066mhz suddenly helped stability a lot, i got 3.6ghz easily.

compuman145 i just want to say thanks a lot for the suggestion on lowering ram clock.

I was suddenly able to hit 3.6ghz+ easily at any voltage when I downclocked my ram to 1066mhz from 1333mhz. So I guess that means it's probably an IMC issue, although could be RAM.

So I'm going to run the same exact settings as I passed 22 hours prime95 (i didnt run the last 2 hours because had somewhere to be, i still have a lot more tweaking and testing to do ;/), except with only a single stick of RAM at 1333mhz, stock. If it passes, it means my IMC struggles with 2 sticks, if it fails, it means my RAM is at issue.
