Getting q6600 stable

[sunrunner20]

I'm wondering what other than vcore can I change to get my G0 stable at 3.6gig (400fsb) Maby NB/SB voltage?

Other than turning on the voltage damper, you're stuck with either giving it more voltage or attaining better cooling (possibly both). The other small bios tweaks aren't really going to help much. You can raise the FSB and get some mem bandwidth to help with some performance.

try raise MCH, and fsb, as was mentioned

Nevermind... mch== northbridge, right?

Oh, and I'm on water now... Haven't changed my sig yet.

i'm having some trouble with the same situation. can't seem to get the q6600 fully stable at 9x400 on an IP-35 pro with Ultima-90 heatsink. hs and core are lapped. it runs all benchmarks & games just fine at 1.50 vcore... but prime95 only runs for a few minutes before it reboots. tried up to 1.55vcore. temps get up to 79c on hottest core under load.

messed with some other settings on the mobo, no help. trying to decide if i should leave it at 3.6ghz since everything but prime95 works ok, or roll it back 1x.

Are you sure that it is actually your CPU that is cuasing instability? You are using a pretty low FSB...

What vcore is the CPu currently at?

If you are sure that it is your CPU, then:

You can try raising FSB voltage 1.4v

you do not need to raise northbridge voltage at 400FSB, though you can try. You also may try to raise reference voltage of northbridge slightly...

You may want to increase PLL to 1.6v

increase the reference voltage of your CPU slightly if you haven't already.

Do not forget that too much voltage (even if the board is designed to withstand the
voltage) is as bad as not enough....

Try setting CPU Reference voltage to 0.63x.

Also, make sure voltage damper is enabled.

You might try dropping the multiplier 1 tick and run the fsb the same, to rule out mem problems...if it runs stable, you could push the fsb, to find out where the mem tops out.
