I have just bought the same MB havent used it yet but know how to overclock it by reading, reading and reading!

How have you tried to overclock?

i've done a lot of reading also. First i just tried to OC by the multiplier. It stops loading windows at 16x at 200 fsb and it doesn't matter how much voltage i give it. I tried to loosen my ram timings, and turn off cool & quiet and c1e. I disabled the TLB patch, and even tried to lower my ht-link. No go on anything. ACC is already enabled and i've already tried toggling that to see if it helps. The only thing i havent tried is strictly oc'ing on the fsb. But whats the point in that when i bought a black edition processor.

Try minimally increasing your NB voltage. It worked to keep mine stable.

(As well is C1E & CnQ Disabled, minimal CPU voltage increase, loosened RAM timings to 5-5-5-15)

do we really need to bump any voltages on our southbridge and/or our northbridge?? i thought that since we did not change the fsb, the nb and sb arent stressed so they dont require more volts. is this right? if so then, can someone tell me how to make the change to help my oc on my chip which is stable at 3.2 @ 1.4v, and ddr2 unganged 1066 @2.1, nb auto, sb auto.

Well you can still try NB increase...

Also, I brought my RAM down from 1066 to 800 and it helped as well as well as loosening ram timings. It could be your ram holding you back.

3.2/3.3 is generally the limit on air cooling from what I have seen from everyone.

Do you have the 4 or the 8 pin plug in the CPU power ? Have you tried a combo of Multi / FSB ? set ram to 800mhz and try 15.5 and play with the voltage of NB/ CPU and FSB with Air your only going to get around 3.3ghz - 3.4ghz if you didnt have a black edition you would be stuck at x13multi and stock speeds so for the $10.00 differance you got a few Mhz. and it could also be you MB whats the average others are getting with the same MBs The Asus seems to get the best OC for the Kuma ATM. I dont know if it makes a difference or not but your ram is SLI ready ram On a Crossfire board and AMD/ ATI chipset.

I have a 4pin plug, and i've tried increasing voltage in small increments already. I've already tried to loosen the ram timings, and even went as high as 6-6-6-18. yeah i've tried messing with the multi+fsb oc. right now i'm running at 15.5x at 200. I've tried looking for others with the same mb/cpu combo but only found one person at 3.1 also. Couldn't find any other numbers. My psu is pretty old and i'm currently looking for a new psu. Hoping to get a 600w or 700w ocz for $50 and under AR.

the 4 pin plug will hold you back , I tried it with both 4 pin and 8 pin cpu power much more stable with 8 3.2ghz is about normal for my 24/7 OC everything is much more stable and cooler. You shouldn't be upset with 3.1 that's a nice OC on average after all its just an already failed quad core reborn. for dirt cheap prices.
