Thread: GA-EP45-UD3P stable but do I need to tweak memory settings

    Default GA-EP45-UD3P stable but do I need to tweak memory settings

    Thanks again to everyone, OK.... my computer is running stable except when playing games,most every game! After playing for varying amounts of time the computer freezes and gives an the error [DISPLAY DRIVER NVLDDMKM HAS STOPPED WORKING AND HAS RECOVERD] and I have to go to task manager to stop application and restart windows.From all the info on the net its impossible to pinpoint the problem but most agree its a memory settings problem, so hopefully someone can point me in the right direction. Here are my settings,

    Default Re: GA-EP45-UD3P stable but do I need to tweak memory settings

    Well tweaking your memory settings isn't a "Have To" kind of thing, most often you can gain some improvements though.

    From looking at your settings, I would suggest you start over again by loading optimized defaults then save and apply and reboot back to the BIOS. Then set your SATA/Disk settings again and then go into MIT and set some of your settings you have over again. I suggest this because I can tell by your settings (CPU/PCI Clock Drive - Should be 800/900) that you have started with Fail Safe Settings and this is not suggested.

    Please do load optimized and save/apply/reboot, do not just change the settings I mentioned that pointed it out to me as there is also some hidden settings that may be set improperly per your hardware if you do not do it this way.

    As for your error, that is a well known Nvidia Driver error..... And if you google can be said to be caused by 1-1000 things, all of which I believe is only actually the drivers themselves. I switched to ATI Based cards a few years ago because of this and have not looked back.

    What you can try to do is try different driver versions, older or newer. Latest isn't always the best.

    Here is a few sites where you can get older versions >>
    Windows XP/2000 Driver Archive
    download from Guru3D.com

    If I need them for ANYTHING, I grab them here. Don't mind the name they will all be desktop drivers >>
    Download NVIDIA drivers | drivers for mobile cards and laptops | laptopvideo2go.com

    You can also look through the forums there and see who is using what by searching for your card by name and maybe find some drivers that work well with your card

    About your actual settings, we do need the actual # of your Memory so we can look it up before suggesting fully. I can say to you now though that you need to set your MCH Voltage for 2x2GB, 1.18-1.24 should be good. And you are running your memory at 800Mhz, did you know this?

    Once you have loaded optimized post back and give us your memory model # and we can better advise. If you are unsure of your model # you can look with CPU-z in the "SPD" Tab or just look on the ram itself, should be printed on the sticker

    Default Re: GA-EP45-UD3P stable but do I need to tweak memory settings

    Thanks for the quick reply Lsdmeasap, I don't see how you keep up with all the requested help. Anyway... I loaded optimized defaults saved and booted back to BIOS. As for the memory running at 800Mhz if I set the multiplyer to any thing other than (2.40B) I get the GIGA-BOOT-LOOP. I have run memtest86 on both sticks for 24hrs with no errors reported. Mem# (F2-8500CL5D-4GBPK). I'll resend my settings since changing them ASAP.

    Also note that the most common causes of the error you're receiveing isn't system RAm (though it's possible). Unstable/corrupt video drivers or an unstable overclock can cause that message to be displayed, as can an over heating GPU. I frequently got the ATI equivalent of that message when finding my max GPU clocks.

    OK.... my computer is running stable except when playing games,most every game!
    To be 100% sure your system is stable, when you have it set up again as required, with optimized defaults, I suggest you run some stability tests before moving on to sort the GPU problem. 10 runs of IBT and at least 8 hours Prime/Orthos/OCCT on blend/medium will confirm that you should be 3D stable at least. With this done, you can eliminate the RAM, CPU etc from the equation and concentrate on the GPU (clocks, cooling, drivers etc). If Prime etc fails, then it's your system maybe causing the display driver crashes.

    check your nvidia driver installation

    type dxdiag in the search box in start and run it.it usually gives a good indication if the drivers are ok or not..
    If you are going to reinstall/use new nvidia drivers make sure the old ones are cleaned out properly with
    Guru3D - Driver Sweeper

    Ive seen the error u describe on 3dmark when pushing my overclock,but generally its when pushing the gx card overclock not the cpu/main memory.

    However on the main memory turn off turbo and use standard instead those figures you list in your bios sheet for memory timings wont be whats applied if you use turbo.ie tRFC will be more like 52 instead of 68.
    and test.
    Try full standard voltage on the gskills too.
    When they quote a voltage range some sticks work fine on the lower 2.0v (2.0-2.1v in your case) but then others seem to need the full 2.1v.
    Also 2.04 in bios could be more like 2.01-2.02 in practice.

    2.1v isnt a do not exceed voltage either, its more the upper limit needed for the memory to operate at 1066 (Gskill have found).

    Default Re: GA-EP45-UD3P stable but do I need to tweak memory settings

    MCH Core = 1.20 - 1.26 is probably needed. Values that are too high or too low will cause instability or boot problems. Once your system is stable with the proper bios settings, 1066 memory speeds should not be a problem.

    Please add your hardware list from the first post to your forum signature, as this will eliminate errors and make it easier for us.

    You should be able to use 3.20B for 1066Mhz ram speed, you may need to find proper MCH and Vtt voltage first though, and raise tRD (Static tRead Value) to 8-9 until you get things going

    Default Re: GA-EP45-UD3P stable but do I need to tweak memory settings

    I've tried some the suggested settings but still get the boot loop when I set set the RAM speed to 1066, I have to take out 1 stick and reboot to change back to 800.As I said before I ran memtest for 24 hrs on both sticks and did not recieve any errors. With my work schedule. Here are some of the screen shots and BIOS.

    Default Re: GA-EP45-UD3P stable but do I need to tweak memory settings

    From the Memset screen-shots of your RAM's SPD, it seems that the BIOS is setting tRFC and maybe some other advanced timings tighter than the RAM is rated for. You will notice that Memset says your current tRFC is set to 52. Even if the value on the left of auto states 68 in the BIOS I would still set this manually for now as obviously the board isn't being honest about the values it's using.

    I would set the Advanced Timings to read:

    Advanced Timing Control
    tRRD...........................................4 [5]
    tWTR.......................................... 4 [5]
    tWR............................................13 [10] 13 is a bit too loose, even for safe settings. Normal range for 4gb is 6-10
    tRFC...........................................68 [68]
    tRTP........................................... 4 [5]
    Command Rate (CMD) ....................:2

    If these settings don't help, cycle through other RAM multipliers that give you more than DDR-800. If one of these work, at least it will give you more theoretical performance than DDR-800.

    Alternatively, your RAM is probably capable of running at 4-4-4-12 main timings at its maximum rated voltage using the 2.00B strap (try 2.00D if that one doesn't work). this will go some way to offsetting the speed difference compared to DDR-1066 at 5-5-5-15. Gaming performance is virtually identical (for me) at either DDR-800 or DDR-1066.
