You will usually need +200 VTT voltage to get that memory stable. VTT voltage can also be labled QPI voltage or uncore voltage depending on the bio or board manufacture. It's a very typical adjustment for i7 machines.
It can also help to reduce the memory voltage to 1.60 as that particlar memory has problems with higher voltages.
Asus P5 series of mobo's - particularly the P5Q seem to have an inordinate amount of problems.
Asus mobo's have a driver for an ATK0100 device named ASACPI.SYS. When you install Windows 7 it will install a copy of ASACPI.SYS from 2005. This will cause BSOD's on many Asus mobo's.
I haven't heard of this issue with the RTM and Asus P6T mobo's - but can't be sure of what's causing it.
Thanks for your inputs.
Chev65 - It think you are spot on.
I have adjusted the voltages in XMP profile and the system seems now stable!
MANY THANKS FOR HELPING US GUYS!
Well I rejoiced too soon.
Set the XMP profile in Bios (with Dram voltage 1.60 and QPI voltage 1.55)
Have also udated the ASACPI.SYS to the 2009 version
Got two more BSODs.
dumpfiles attached. Any ideas?!?
Most P5 board issues seem to revolve around memory, cpu, or video card voltages.
I'd also suggest an update of the BIOS to the most recent version (this has helped on occasion).
I don't adjust my voltages - so I can't help you out with suggestions there. Everything I use is set on "Default".
