I am have hit a wall trying to get my memory to run at the rated 1200MHZ speed. I have the ram booting at DDr2-900MHZ but any higher and it fails to boot. I've tried everything I can think of to get it to 1200. Can anyone help me out. THX

  1. The P5E is rated to use DDR2-1067, however you should be able to get to around 480 FSB before having to increase the NB voltage to get upto and over if your lucky 500 FSB/ DDR2 1000.

    For a start set your voltages up manually the P5E is good at giving you a general indication as to when a voltage is too high via the number changing colour in a traffic light way. Now atm i can't give exact figures as i'm not on my P5E comp so you'll have to take advice from somebody else or what is probably the better course, the use of trail and error.

    I'd guess that your vcore needs to be increased in steps to get past 450FSB. You'll hit another wall at around 480-490 FSB and need to increase the NB voltage aswell in steps till it boots at 500 FSB after that it's pure trail and error for your specific system to get over 500 FSB. :)

    Thge most i've had is 523 FSB...
  2. Try not running the ram 1:1 AKA use different strap.

    At 450 you need more vots then auto is supplying you. Run your vcore manually. Also lock your PCI e at 100.

    Read some overclock stickys.
  3. I apologize for the delay in updates. I've been trying in vain to get this ram to run at 1200 all weekend. I lowered the frontside bus to 266 and multiplier back to 9 to give me the default speed for my processor. At that point i could set one stick to run at 1066 and that worked fine but I could not stabily achieve two sticks at 1066 no matter what I did. I'm just going to return the board and probably get a 680i chipset board.
  4. Can anyone recommend a board this ram will work in or should I return the ram as well?
