125W C3 Overclock better. Worth the Extra 10 for sure!

Hello everyone - first post here.

This is my Phenom II X4 955 C2 stepping - running stable so far at 1.475v 3820Mhz and 2400 CPU-NB at 1.25v.

Only tested for 45 minutes in Prime blend as I've already tested and used it in games and other CPU intensive programs on my old motherboard.

This is on my new Gigabyte MA790X-UD3P (wanted the UD4P but you can't get it anymore in Europe. But it's not a big deal as the differences between the two are in bundle (the UD3P has a very "budgety" bundle and no extra USB/eSATA brackets, no on-chip Dolby decoding and some other stuff like a heatpipe between the NB and the MOSFET cooler.)

On my previous ASRock A780GXH 128M i couldn't get it stable at 1.475V - it crashed early Priming and in seconds in Cinebench. Stable required 1.4875 which was more like 1.52-1.54 under load. The Gigabyte is clearly the much better overclocker and i haven't event started tweaking it yet. As a bonus, the HT bus speed on the Gigabyte is 1,8 Mhz faster so on this board the chip is actually 35 Mhz faster at the same multi.

The temps are a bit high, i know, but i doesn't come close to what Prime pushes out of the chip when gaming or doing other CPU intensive stuff.
Actually had to reseat the cooler because i put too much TIM the first time (used to my old Core Contact Freezer which required more paste) and the temps sky-rocketed to the 60 degrees mark in 1-2 minutes of Prime. It only reaches 60 now after 20 minute of Prime.

Cooling is a ZEROtherm ZEN FZ120 lapped with 2 Scythe Slip stream 120mm 1200 RPM coolers mounted in push-pull.

How do you guys running on air get so low temperatures under Prime? Do you sacrifice noise for better CFM? These Slip streams are really quiet but only push out ~47 CFM (real, measured) each.Attachment 134399

60 is pushing it. The chip overclocks stable under 55 preferrably under 50 load.


60 will turn into easily 64 after an hour.

What's the difference between OCCT and P95? I ran my cpu @ 3,8 Gzh & 1,45v on Prime95 small FFTs for 2 hours and then started the OCCT (after running prime) and it crashed in like 20 seconds :S I'm lost....

Either your RAM or CPU-NB (IMC) is unstable.

Prime95 small FFTs will only stress the CPU. OCCT will test the IMC and RAM a bit but it's mostly still for just the CPU.

Run Prime95 blend (at least 3 hours) to really stress it all.

But i did passed 3 hours OCCT @ 3600 with the same settings....

Hi...just got my C3 this afternoon and have been playing around with it...so here are some scores...will add more benchmarks as we go along.

Highest OC - Suicide run - 4.4Ghz - AIR

CPU-Z Validator 3.1

Super pi run at 4.2 Ghz, NB at 2925 Ghz ad memory at 1500 Ghz.



Will add some more soon.

nice voltage will be nice to see what your stable OC will be on air.
