I can't seem to get it stable at 3.0ghz.

At 3.0, every once in awhile it will crash by crashing my display. I know it's my CPU and not my GPU because when I kick it back to 2.9 it runs fine 24/7. Should I just give it more juice (volts)? I currently idle at 39c without a voltage increase.

Any ideas? I know my chipset may not be helping me out, but I plan on fixing that when I upgrade to AM3 when/if that happens.

Cavi, sounds like you need to give it a tad more juice. I needed to add +0.025 when I had my 7750+ to get it stable at 3.0. Finally settled for 3.2Ghz @ 1.375v.

Hi guys, I have my Kuma @ 3.2 with stock cooling. Temps with Prime95 large FFTs seem great considering, and I think my chip has more potential. I'm aware of the huge voltage bump needed to go above this region, and my motherboard isn't necessarily very welcoming to it. The voltage adjustments for the CPU are +.05 and +.1, but my board has no VRM coolers so I get ENORMOUS range of vcore.

I know my memory can't overclock. I had it in an intel rig and it became unstable @ 850 6-6-6-18.

Screen was taken at load, all advice is hugely appreciated.

Thread owner, can't you make this 7750/7850 thread?

Both same chip, one with higher stock multi. I can find proof of this if you need.

Hi guys,

Fancy winning some money and/or great OCN prizes?

Why not try OCN's benchmark speed test contest here

With my south bridge, I only have three incremental options for voltages (+50mV, +100mV, +150mV).

I jacked that all the way up, and STILL can't keep 3.0 stable for some reason

Ok, looks like I'm going to start paying with FSB (or whatever AMD calls it) to try and get it higher now. Hopefully later tonight I'll have some sort of success story.

It's a shame I can't just jack up the multi like everyone else lol

Why can't you?

It will still need the added voltage, even if it's at 3GHz+ via multi or 3Ghz+ via FSB...

I thought this was your problem.

Yeah I know I will still need the added voltage, but the CPU isn't stable at 3.0 with a simple multi increase and the added voltage, therefore I am going to try and messing with the FSB now to try and get it to 3.0 stable as opposed to simply trying to increase the multiplier.

Flash to newest bios? Turn on ACC to "Auto"?
