6850 will not over clock

[turtle1]

I just replaced my E6700 with a E6850 (was a gift). I updated my bios and everything works great. However as soon as I try to over clock (minimal 10% OC via AI Options in bios) and restart computer, I then get a BSOD and an automatic reboot when they system enters windows... With the E6700 the system has run rock stable at 20% OC using the same method for the past 3 months.

My system:
Vista Ultimate 32
Asus Striker, bios 1303
E6850, air cooled using stock cooler
4 Gigs Corsair XMS2-6400C4 Xtreme, 4-4-4-12-2T @ 2.0 volts
BFG 8800GTX OC (factory OC)
2x 150 gig Raptors (non-raid) and a Segate 400 gig SATA drive.
P&C 750 watt PSU
Onboard sound

My one guess would be to try to up the memory voltage some which I have not done yet.

Any ideas? Your help is appreciated...

I'm not having a go at you for posting in the wrong section because TBH I don't care, however you might find this useful to you http://www.tomshardware.com/forum/244029-29-help-overclocking-evga-680i-motherboard-memory#t1733061 then again you might not, but it could be worth a look.

Thank you. That should be a help. I appreciate it.

As far as the wrong section, this could have been posted in Homebuilt (which I did), Overclocking, CPU and components, Memory (as it might be a memory timing issue), etc. I have had my best luck with Homebuilt so that is why I decided to post here.

No worries mate, like I said I wasn't having a pop, but there is always someone who will.

Without a bit more information its hard to say. The most obvious difference between the two CPUs is one is 1066 FSB and the other is 1333FSB.

A 20% OC on the 266MHz bus would put it at about 320MHz, where as the other CPU starts out at 333MHz.

If the RAM is still at the same ratio then you are going to be OCing your RAM farther at base speeds on the new CPU then what the OC on the old CPU did.

Without knowing more about how everything is set up, that would be my first guess. Change the RAM to 1:1 and see if that helps.

Thank you. I will try the 1:1 ratio. If that does not help I can push up the memory voltage some.
