    Default EP45-DS3L & OCZ XTC 4x1Gb hard locks and rebooting loop

    Playing STALKER: Shadows of Chernobyl with oblivion lost and float32 I end up with a hard lock (grey screen) and when I reboot my system gets stuck in a loop powering up over and over unable to post. I haven't had a problem like this in any other games so far. Booting there are no beeps or any errors and frequently it doesn't even get far enough to display any video output before reseting again or try and get into the BIOS. I can only post after powering down and pulling out any two sticks of ram and posting successfully and then reseating the sticks. I can't see why that would make any difference what so ever but it does. During all those failed posts sometimes I would get a bios checksum error and it would revert to the bios the motherboard shipped with (f5) and then fail to post again anyway.

    The dram voltage is set to 2.1v and the MCH core is at 1.2V as the auto settings of 1.8 and 1.1 won't let me post at all. All timings are set to auto but I've tried all sorts of looser timings in threads troubleshooting 4x1gb setups on the gigabyte ep45 with no luck. The memory can pass memtest86+ all night and day with no errors. Using the latest bios (f10). Everything stock, no overclocking.

    I don't have another motherboard to try swapping. I've had this CPU/motherboard for about a half year or more now and aside from having to bump the dram voltage to 1.2v when I first put it together I haven't had any issues posting otherwise until now. I'm about ready to blow even more money, not that I can really afford to right now, on yet another PSU (Enermax Modu82+ 625) and 2x2Gb sticks of memory (Mushkin HP2 6400 4GB) along with some other ep45 motherboard. The worst part is even RMAing the motherboard I'd have to buy a new one first to use as I need the internet for work and this is the only box I can use my 56k modem with. :(

    Perhaps related: I end up with nvlddkvm TDRs in Vista playing pretty much every game randomly and generally infrequently. The problem persists even after swapping the gpu (with a 8800gt), a different (same model) power supply and different sticks of ram (again same model). This one particular issue does not occur under XP - only in Vista which I first installed early last month after finally getting some games that actually have a benefit to using dx10.

    Replaced the OCZ for Mushkin HP2-6400 DDR2-800 2x2Gb and everything seemed good for a week or so and boom. Grey screen in Left 4 Dead every few minutes hard locking the system sometimes with audio looping. The latest reboot got stuck in a loop failing to power up several times before turning it off and trying again were it booted fine. :(

    I'm thinking this may be your PSU, what brand and model is it?

    Try running prime 95 for several hours, memtest does not always give errors even if there is a problem. If prime 95 works your problems are likely video card or PSU related.

    Have you changed any BIOS settings or are they still like the above post with not overclocking?

    Seasonic S12-500HT which was rock solid with my a8n32sli and x2 3800.

    I've tried two different GPUs (8800gt and the gtx 260), APUs (audigy 2 and the xfi) and the different RAM and the problem persists. The BIOS settings are the same as above other than the auto timings for the mushkin is different. 5-4-4-12

    What about Prime 95?

    The last time I did stability testing which was when I first put together this rig prime 95 was fine over both cores. Going to let it run for 12hr or so overnight.

    Priming both cores with blended stress test for 12 hours now and still going with no errors. Doing this under XP32 as Vista64 lags awfully bad with both cores maxed out. The mouse won't move smoothly and there is about 2 minutes of lag interacting with the GUI. XP is smooth and responsive. Speedfan is either borked or something is wrong with the PSU's 12V rail as it is reporting 2.5-3.2v.

    Prior to priming yesterday I tried...
    1) playing with -nosound and still locks. Guess its not an x-fi driver issue.
    2) Tried it under XP and it hard locks so its not a Vista being Vistay issue.
    3) Read 181/180.xx drivers caused some problems for people so I tried 178.24 which seems to be recommended for l4d. Managed to play through two campaigns fine, went to quit and boom: "Windows Service Exception" BSOD with nothing in event viewer about it which I can't even find a single thing for on google. o.0 Going to have to play more with these drivers to make sure its not still going to hard lock during gameplay.

    Do you ahve a differnt PSU you could try? While the PSU is a very good unit, it's rather old I guess and it's not uncommon even for quality PSUs to start dying slowly after a couple of years.

    Again, the symptoms sound very much like it's the PSU.

    Not at the moment. Ordering an Enermax EMD625AWT MODU82+ 625W after reading silentpcreviews.com's review. Was going to just grab a Corsair HX620W as they are re-branded Seasonics but this seems as good and less noise is always good in my books.

    before getting rid of what may be an ok psu. Consider vdroop.(voltage drop).
    This increases with load, on both memory and cpu.
    For memory increase voltage by .05 volt,
    This should compensate for any increased v drop with running vista etc.
    Were all using "performance memory" and we dont really run it on stock voltages.
    Voltage drop varies from psu to psu not the motherboard.
    Its relatively easy to check .
    Utilities like speedfan will monitor the vdroop on both cpu and memory while running.
    dont go over 2.3v in bios ,not for 24/7 running at least even if your vdroop is huge.

    If it gets locked in "continuous reboot" turn off the psu switch before hitting the button again and allways load optimum settings first before anymore bios changes if youve had a "fail".
