    Windows BSOD help

    Ok so im having a little trouble with my new build, the build works totaly fine at stock BIOS settings.

    What I am doing which seems to cause this error is changing the X.M.P. (Xtreme Memory Profile) in the BIOS to 'PROFILE1', this changes the RAM voltage to 1.65V and also boosts the frequency from 1066MHz to 2002MHz. I then booted to the desktop and started the windows performance information scan, it gave me a blue screen of death (BSOD) and rebooted my pc.
    After this every time I get the BSOD on bootup before reaching the desktop. Currently I changed back the X.M.P to 'Normal' and I no longer get the BSOD, but why spend so much money on 2000MHz RAM when it can only run in 1066MHz.

    My Specs are:
    Windows Vista 64-bit SP1
    Intel Core i7 950
    GigaByte GA-EX58-UD5
    Corsair Dominator GT DDR3 6GB (2000MHz) [TR3X6G2000C8GTF]
    Nvidia Geforce 280

    If anyone can please help me I would be extreemly happy

    I've just double checked the RAM's specs from Corsair's website and you should indeed be able to run the memory at 1.65V at 2000MHz. However, the voltage shown on the BIOS might not be the voltage reaching the chips so you might need to change the voltage a little. Be very careful though, AFAIK DDR3 is very sensetive to overvolting so do you have a multimeter you could check the voltage with? BTW I wouldn't recommend changing the voltage just because I said so as I haven't had any experience with DDR3 and I wouldn't want you to fry it. Wait for someone else to confirm or better still, ask in the Corsair part of this forum as you will get an answer from a Corsair rep.

    Thanks for your post watercooled and double checking for me

    I turned back on the X.M.P but I also changed the voltages manualy in the BIOS to 1.64V vdimm (RAM Voltage) and the Uncore voltage (QPI/VTT) to 1.6V.
    I set the ram to multiplier to x14 (i think) which is 2002MHz
    I also changed the timings of the RAM to 8-8-8-24 @ 1T (or 1N)

    I also turned down the RAM boost from 'Turbo' to 'Normal'

    Everything seems to be running perfectly now

    The next thing on my list is reducing the Uncore voltage in small imcriments to find the lowest possible stable voltage.

    Great I'm glad you got it sorted. The 'turbo' functions on a lot of high end motherboards are, I assume, an easy way to add a small overclock to your components but if you are changing the settings yourself you should turn it off as it can mess with voltages/clock speeds and cause instability or even damage components if it turns up the voltage too much.
