    Ouch, your settings broke my eyes!


    Feel free to post back directly on the forum, for now I see several possible issues with your settings, aside from the main one. You are using Fail Safe defaults to start with, this is not good at all.

    Please load optimized defaults and save/apply/reboot F10. Then when you reboot go DIRECTLY back to the BIOS and set your SATA/Disk setting, this is very important if you are using RAID!!

    Then set your memory settings and anything else you need to change and try again. Fail Safe may be causing the issues, but maybe not.

    QVL list is very small, and dated. They can't test everything on every board, so yes it could be an issue

    I also note you are using XMP, I advise against this and will help you once you do the optimized thing. You may also want to see this, in regards to XMP and this kit

    Anyway, don't matter because I will help you set it up properly without XMP.

    So the memory kit itself is compatible, so you can rule that out as an issue. I found many more threads as well, so you can be sure it is fine. Of course some of those are people with other issues, but the memory works fine with the X58A boards, and the older EX58 Boards which is were the compatibility would have been carried over from the X58A anyway.

    I can help with settings for sure, but we need to rule our bent CPU pins, and possibly PSU as well if you can first.

    Hey,

    I used the load optimised defaults option, rebooted, then went back to restore my OC'd BCLK. I still haven't managed to get the memory working correctly but I'll post updated bios settings in a moment.

    I've had a lot of free time this week because the Easter break means no classes but at this stage I have a few projects which I have to get done before Monday so this is slightly on the backburner until I finish the main one (kernel memory paging simulator in C, oddly enough).

    After reading some of those links, I'm inclined to think that memory incompatibility seems highly unlikely. Having said that, these are the posts of someone else having the same issue with the same parts who fixed it by switching to a different memory kit (1 2) so who knows. The PSU is a good quality Seasonic one so it's probably less likely to be the fault. A lot of this is complicated because my old PC only has a 550W power supply and can't support a 5870 on that to test (which I also want to because of the other issue).

    I'll get the photos done when I can afford the time it takes to disassemble it and get a thorough look at it [but I need the PC for work right now].

    Appreciate the help greatly nonetheless.

    Well those settings you initially posted were not optimized default starting settings, there is a few settings that lets me know, maybe you just missed/had them wrong but I doubt it because you entered fail safe amounts which is what made me notice.

    Ya, I do not think the kit is incompatible at all myself.

    Default Re: X58A-UD3R: Missing Memory only at 1600MHz

    Sorry, I meant I used the optimised defaults between when I posted my settings and when you posted your copy. ;)

    Anyhoo, i used those lower end of those settings and the computer booted, recognised all the RAM but produced one error during a quick Prime95. I'm currently rebooting to install ET6 so I can take some pics of the settings more easily and will also check if it RAM is recognised properly again after a cold boot.

    Edit: Computer's taking its time to POST... hasn't reset by itself though. I've a few reports of slow POSTs with this mobo, actually.
    Edit2: Had to manually reboot it. It reverted to the stock speeds.
    Edit3: Increase QPI to 1.38V, and IOH Core to 1.22V. Rebooted and Windows is loading again - it doesn't like cold boots apparently.
    Edit4: All ram recognised, testing Prime95 - lots of errors again.

    Edit6: Rebooted again but only 2GB of ram is being found.
    Edit7: I don't know if this means anything but when looking in the bios, the '-'s are next to channels A & C again. While testing yesterday and today I don't think I've seen channel B ever be affected. Also, when I rebooted to restore my previous settings (ram at 1280MHz), only 4 GB of ram was detected. Probably the pins? :s

    Ahh ok!

    Ya, you will have to tinker around until you find the sweet spot, the settings I posted are just a general guess at what might get you started going in the right direction.

    If you are running 1700Mhz you may need 1.4-1.45 QPI/Vtt, try that and see if all memory is detected properly. That or you may need to go back to 1360Mhz for now so you can rule out the memory as the cause for errors as it may not like 1700Mhz (Some G.Skill is binned very tight and wont overclock much)

    Okay, I dropped the memory to 1360MHz while leaving all the other settings the same and Prime95 looks like it's solid. All 6GB of memory is being recognise this boot but again it's intermittent so can't be sure of future boots.

    As a side note, is it a bad thing to disable EIST? I noticed that the TDP dropped to like 25W instead of the constant 150W or so under load which seems like a good saving.

    Cool well if it remains, then the issue is just finding the correct voltages for higher memory speeds so you dont drop channels is all.

    EIST and C1E should be disabled since you are overclocking. I am not sure what you are asking though

    Cool. I have to head off for tonight but what setting should I change next? More QPI towards 1.4V?

    I just meant that it'd be nice if we could overclock and still have the CPU "power down" when idle so it didn't use as much power. :)

    It's cool, I am bout to head out as well. Yes, I would try more QPI/Vtt and IOH and see how things go, it's not a "plug n play" kinda thing, you need to tinker around a bit so don't let it upset you.

    Well you can, sometimes, but it is generally a huge hassle and could take you weeks to get it working stable like that. Best to just disable for now, then once you are stable and have time to kill you can try tinkering again and spend a while trying a new profile with those enabled.

    Have a good day, I'll see ya later this afternoon or tonight
