I think you could come down on the CPU volts my Q9650 will do 4050mhz at 1.42(actual, 1.33 BIOS LLC enabled)...the trick for me to get 8GB stable in prime was 1.62v NB AND 2.06v MEM volts....more CPU volts was not helping me.

I hit a wall at 1840, Memtest 2 full passes, I can post and boot Vista at 4140mhz 1840FSB L&S but it's not prime95 stable. I have tried an ton of things but nothing is working...I think I have to find a magic CPU GTL combo.

What's weird is if I go even 1mhz above 1840 system will not post period, I tried a bazillon settings and never once got it to post above 1840.

Here's my Q9650 8GB volts/settings etc... maybe it'll help.

Edit..Hurrmm cpu-z says 1.44..it's been reading 1.42 for the last few days all of a sudden it's 1.44 weird. Have to try dropping down one in BIOS and re stress test.
Your Q9650 is a better stepping(E0) than my QX9650(C0), hence your chip although multi locked would fair better @ higher FSBs/clocks.Also, I can't get this freaking thing to post @1600 RAM linked/synced for 400x9.5=same 3.8GHZ. I guess I would have to try harder. The wierd thing is I was one of the first ones with this board to do 4GHZ on my QX9650 with my 2GB GSkill BHZs(445x9), 12 hours prime stable with 1.375 Vcore with LLC, which I guess gives me 1.44 or thereabouts, on air.So my theory is that for core 2 quads, the way they have been architected(2 C2Ds stuck back to back), might have to do something with it(the more the RAM, the more Vcore it needs to be stable @the same speed). I could be wrong on this.

The voltage anomalies that you see if one of the main culprits of this board that leads to a lot of instablities. Guess what, just for the kicks, I rebooted with the same exact settings and ran prime again and it failed just after 2 hours on one of the cores, as it had dropped my vcore compared to the previous run of being 8 hours prime stable,with the same BIOS setting.It could be that the software that I am using that gives the vocre might be wrong,but I doubt and prime failing kinda confirms this. It's either the BIOS(software) or the PWM/power delivery(hardware).I was this close to tossing this board out and buying a good x48 board, so that I can swap my GTX 260 tri-sli to my Classified build and have the 4870x2+4890 crossfireX combo on the x48, but resisted it.The only reason that I am keeping this rig eventhough I am building an i7 rig is that I am planning to go water on my i7 build sometime and I wanted a high end backup gaming rig(air cooled) just in case something goes wrong(first time planning to go water and the thought itself scares the heck outta me).
