EX58-UD5 and OCZ 6x2GB=12GB and i7-920 =restarts after windows loading


Bought my self new MB, RAM and CPU

EX58-UD5 newest bios (beta)
OCZ DDR3 PC3-12800 1600Mhz Platinum Tri channel kit 6GB X 2 7-7-7-24 1.64V

Problem: Computer restarts when windows have finished loading.

My old computer is a 755 intel MB with e6600 and ddr2.
So I can´t change parts with it..

Ive tried the 3 different windows XP,Vista and win 7, I have win 7 currently installed.

I can run the win 7 on my old system , just fine, so my GPU and HDD is working correctly.

I though it would be the ram, Ive tried to use them one by one,, all of them. I dont got any other ddr3 ram so I cant change to any thing else then my OCZ 1600mhz.
They are running 1066 at the 7-7-7-16 timing at auto 1.5V.
I have manualy set them at 7-7-7-24 1.64V, 1600mhz and 1066mhz nothing changed.
I got them running auto again.
As i wrote I cannot change them with any other ram. And I dont know any one that got any ddr3 ram.

My cpu i7-920, its running at 35C idle, I applied new paste on them.

My MB is the EX58-UD5, the bios is completly new to me. But ive set the prioritys correctly, it boots fine , its only when Its finished loading Win7, it restarts. IVe even flashed it with the newest beta drivers.

My GPU is working since ive tried it in my old setup.

My PSU is 620W, plenty.

I have no idea to do next, and would appreciate someone elses opinions, and experience.

Thnx for reading this to long text.

  1. Try a CMOS reset, and set everything to auto. You may also want to check your memory.
  2. Ive had everything in auto, and ive loaded fail safe and optimized settings.
  3. Are these all fresh installs of Windows, or did you move your boot drive from the old system?
  4. This passes multiple memtestx86 passes ?

    Have you tried 1,2,3,4 sticks instead of 6 for the memory?

    If you haven't yet done it, start with a BIOS' "Load Optimized Defaults"

    Before we start ramping things up, I want to teach you a new skill involving the BIOS: Do the <DEL> at the boot to enter the BIOS; notice, at the bottom, the <F11> "Save CMOS to BIOS" - hit this, and you should get a menu that will show a number (the count varies by BIOS) of empty 'slots', each of which will store an entire set of BIOS parameters, to be re-loaded from the corresponding <F12> "Load CMOS from BIOS"; this is a wonderful overclocker's feature. What I do with it, is to save my 'baseline' working parameters, so if I change something that 'irritates' the board, and forces a reset of all the parameters to defaults, or, even worse, get so screwed up I need to do a 'clear CMOS', I can get back to my starting point with no effort, and without having to remember 85 separate settings! Another thing it prevents is two hours' troubleshooting, having forgotten a change to a crucial parameter - like, "wait a minute - didn't I have the Trd at seven?!" It's pretty self-explanatory, and I alway urge people to start right away by taking the time to give the 'slots' names that mean something: in two hours, "Try2" and "Try3" will not be very helpful, but "450@+10MCH" and "450@+15MCH" will! Another use is for 'green' settings; overclocks, as a rule, do not 'play well' with green features, such as 'down-clocking' and 'down-volting'; with the storage slots, you can set up one profile, say "Green", with all the settings at 'stock' values, and all the 'green' features
    enabled; another, say "Balls2Wall" with a full overclock, and all the 'green' stuff turned off... Another neat feature of this 'slot' system is, for most BIOS, the mechanism itself will keep track of which ones have booted successfully, and how many times (up to, I believe, a max of five)!

    And that should do it!

    I should point out that getting two reboots in a row here is perfectly normal behavior; it seems that, when you change certain settings (and we don't exactly know which ones - the only sure one I know is Trd - if you change it, I think you get the 'twin' reboot) it boots once to 'see where it's at', recalculates its remaining 'auto' settings, saves them, and then boots again. Three reboots in a row, however, usually indicates that the board was 'given indigestion' by your settings, and is going back to defaults. This sometimes goes astray, and it doesn't get back into proper operation - for example, at this point, mine will sometimes 'lock' itself into 111MHz x a six multiplier - and take a week to do a whole boot - that's time to do a CMOS reset, and use your 'stored' <F12> profile to get back to where you were...

    Good luck!
