I have had this issue a couple of times now and I really don't know where start looking. It doesn't happen often, but on occasion the PC freezes all USB ports shutdown. Only way to get it back is to do a reboot or hit the reset button. I don't know if it is a Vista issue or a hardware issue. No related errors in Event Viewer. Last night I opened a webpage and in the middle of loading the page everything locked up and the keyboard, mouse etc., just lights out. The monitor stayed on, but the webpage just stopped loading at mid point. Nothing else worked. I have the latest bios and I have been leaving the PC on for extended periods without turning it off, but that shouldn't matter. I wondering if it is the PSU or the Mobo? Can anyone else say they have seen this?

that is with an Extreme Memory Profile enabled in the BIOS.

Disable those profiles, leave one memory stick installed only, and manually set the memory to DDR3-1066. Raise the DRAM Voltage to 1.6V in BIOS and then retest.

Why disable the profiles when it passed?

Because XMP-Profiles are overclocking profiles and your memory modules are not native DDR3-1333 modules if they need XMP Profiles to enable automatic DDR3-1333 settings (1st and 2nd reason), because your processor natively supports only up to DDR3-1066 (according to Intel specifications) [3rd reason], because you have stability problems (4th reason) and because the fact that memtest86+ did not show any errors does not 100-percently rule out the possibility that your memory settings are the reason for your lockups (sad, but true -> 5th reason).

Especially the 5th reason...I use to believe in memtest as an excellent tool for detecting memory errors. I have seen it isolate many problems over my years of work. However, on my i7, I ran it with a select timings and settings and it passed memtest for over 8 hours. After rebooting and going to Windows, I would get memory parity errors and crashes. I had to retool the memory timings and it fixed it. Memtest is a very good tool to use to find memory problems, but it is not always full proof. Always try to use multiple applications that will stress components for weaknesses.

I am having identical locking up issues and just posted the specs in a new topic under this forum.  Not trying to overclock, just get a stable build without frequent lockups.  Any suggestions would be helpful.

Thanks.

I disabled the Extreme Memory Profile. So now I am running at 1066 mhz with a 7-7-7-18 timing. That just came up in cpuid with the dran settings set to auto. I have not folled with anything dram timings voltages etc. Just disabled the Extreme Memory Profile since you said the i7-920 only supports up to 1066 mhz memory anyway, which I had heard. I have not run memtest again, but I will soon and lets see what happens.

This is the native support. It is capable of going over. There are no guarantees in stability. If you have purchased quality memory you should be fine to OC. My i7 920 is running at 1333mhz perfectly. I had it running at DDR3-1660 with a higher multiplier, but I like where I am now.

X58M

windows vista

where in my cell menu do i turn on my XMP profiles so i can adjust my memory? my pc recognized it at 1066mhz instead of 1333mhz. and, doing this, is it going to make my computer overclock? which i dont want to do because i dont have any water cooling add ons. just 3 fans. is this worth the time to figure out, or can i get more for what ive got without a heating issue?
