    Default Diagnosing Hardware Failure w/EX58-UD5

    I have spent hours and hours to no avail diagnosing my new i7 920 system. The system POSTs and runs fine, but fails Prime95 no matter what I've tried.

    When I first assembled the system, with all default optimum BIOS settings, it would reboot sporadically at any time without warning. After I set the DRAM voltage to 1.66V and the tRAS to 24, the reboots pretty much subsided. Since then I've messed around with OCing the CPU and running the RAM at full spec, and the system seems to run fine during normal use. My temps are always excellent, staying under 50C under load @3.2GHz. But no matter what I've tried with different high and low voltages, tight and loose timings, even and odd multipliers, enabling/disabling things, advanced settings, and absolutely everything else I could find to try, I just cannot get Prime95 to run without errors - even at the most basic performance settings.

    The errors in Prime95 would seem to point to memory issues, but I'm not so sure. My RAM has passed Memtest86+ for ~7 hours at 1600 7-7-7-24 1T. Could also be cache or memory controller, no? At 2.66GHz and 1066, I can run Small FFTs and in-place Large FFTs for an hour with no errors, but Blend fails withing 10 minutes. I can only get a Blend test to run longer if I reduce the "Memory to use" to 800MB. If I OC the CPU or bring the RAM up to 1600, things get less stable under all tests, but are still most unstable under Blend.

    I think I've tried everything, so I'm open to all thoughts about what might be wrong. I've read so many accounts of people going to 3.2G and beyond with little trouble. I'm just convinced I have a hardware problem. The question is, what's the culprit?

    Red face Re: Diagnosing Hardware Failure w/EX58-UD5

    Thanks. When I had the initial problems, I updated the bios from 5 to 7, which fixed nothing. The only bios newer than 7 is beta, which makes me nervous, and I've read some people have had troubles with it. You're running it though. No problems?

    Do you have reason to believe the new bios specifically addresses my problem?

    Certainly I'm willing to try the latest bios before declaring the MB defective. Other than that, I am already running the RAM voltage at 1.66, and changing the QPI/VTT has had absolutely no effect.

    also i read in your sig your using win xp 32? you know your only using half of your 6gb ram with a 32bit os? it will need looser timings, if you had vista 64 it would run with spec timings no trouble

    Wink Re: Diagnosing Hardware Failure w/EX58-UD5

    OK, cool. thanks. I'll try it.

    BTW, I just checked and I actually did up the QPI voltage as part of my original tweaks to stop the sporadic reboots. I'm currently at 1.295V. But my experience adjusting this any further has not affected the Prime95 issue.

    I'll report back after I flash the bios.

    1.260000 should be plenty qpi volt for 3.2,i only use 1.28000 for 3.8ghz

    I wouldn't blame the motherboard as a first choice, not at all.

    Run Memtest86+ 4.0 on each RAM stick seperately, in each slot. Perform one full pass each time. Any failures can be then narrowed down to either RAM slots or Memory modules (if the tests point to hardware failure. For example if stick 1 passes in all slots, then stick 2 fails in all slots, that stick of RAM is probably bad. If a certain slot fails consistently with all RAM sticks, then it's a faulty slot. If you get failures with every slot and every RAM module, then it could be BIOS settings (voltage, timings, frequency), a faulty board, a faulty RAM kit or even a faulty CPU.

    If you get to the lst scenario, follow the general suggestions that are everywhere on this forum to try and stablize your config. If that all fails, then the first thing I'd RMA would be the RAM. Tell OCZ what's happening. They'll likely blame the board, but that's bull 5hit, there's no way they can say that for certain. Perform any tweaks they ask, and if no success get an RMA.

    If the RAM comes back and still things don't work then there are one of two things going on. Firstly the mobo could be defective, or that OCZ RAM may not be compatible with the board. This isn't Gigabytes or OCZ's fault. It sometimes just happens. Even with standards to follow, sometimes components don't play ball as they are expected to. As the board you have is generally a great overclocker, I'd exchange the RAM rather than the board if it were me.

    Yeah, I initially put XP on here as I need to run Pro Tools audio software which doesn't work on 64 bit and is happier on XP than Vista or 7. I'm actually running dual boot, and intend to eventually install Windows 7 as my primary OS. I know about the memory size limitation of XP, but am unaware of it affecting my timings. But like I said, I've tried looser timings including a high tRFC with no apparent changes. Anyway, I'll keep that all in mind moving forward.

    you know your only using half of your 6gb ram with a 32bit os? it will need looser timings, if you had vista 64 it would run with spec timings no trouble
    Having XP 32 bit does NOT mean that timings need to be adjusted at all. Being able to address 6GB of RAM or not is purely a software limitation. There is absolutely no need to have to alter any timings, speeds/frequencies etc.
