I have a q6600 that I'm having an extremely hard time overclocking beyond 3ghz. I have an MSI p43 neo3 mb, decent cpu cooler, and two different ram: 2 gig gskill 800 2.2v - 2 gig patriot 800 1.9 v. I have tried changing the fsb and multiplier with different voltages to cpu and memory, and some fsb. Tired changing times but not sure exactly I was doing. I have also tried just running all patriot mem and can't get to 3ghz while i can get 3ghz with the g.skill and patriot combo. Right now I'm sitting with both memory installed - the cpu voltage at 1.35v - memory at 2v - 9X 333fsb for 3ghz. What can i try to get beyond this limit? Thanks for all your help.

I bet you are inadvertently trying to overclock your memory.

I am unfamiliar with the MSI BIOS. If you are at 3.0 GHz, your CPU should be running at 333 MHz x 9. If your memory timing is on Auto, by the time you have increased your FSB to 333 MHz, your memory clock is right at 1000 MHz.

Go into the BIOS and change whatever you need to get a mem clock twice as high as the FSB. If your FSB is 333 MHz, your memory clock should be 667 MHz. That means if you can get your FSB up 400 MHz, your core speed will be 3.6 GHz and your memory will be right at DDR2-800 speeds.

Because you have two different kinds of memory installed, you may need to loosen the memory timings to 5-5-5-15.

This should help.

With 4 sticks of memory you might have to much stress on your MB so 3GHz may just be your limit. How high have you tried to push your vcore in order to go higher than 3GHz?

I have gone to about 1.4v, but it doesnt seem to really help. I feel like its a memory issue thats holding it back but I can't really be sure....there are a ton of variables sadly

I have a question,,, i can increase my northbridge voltage from .1 to .3 (.3 being the max), does this have more effect on posting successfully or all around OC capability? (having stability during prime95 testing and in games etc...)

I'm currently running an G0 Q6600 (9x400) 3.6GHz on a GA-EP35C-DS3R Gigabyte motherboard, and well i'm using 4.75Vcore stable, however i need to increase my memory voltage .1 in order to be able to sustain gameplay (if + .1 isn't added to memory voltage then i basically can't play demanding games such as BFBC2.)

So my question lies with if increasing MCH or the northbridge may stabalize my 3.6GHz OC, possibly allowing me to lower my vcore, what exactly does MCH effect during boot and while in windows?

i wouldn't do that on the NB. the q6600 doesn't OC well. if i were you, i would probably stop.

emm, i'm having a hard time believing that the Q6600 doesn't overclock well..

i'm just curious as to why one would actually increase the volts on the northbridge.
