    Default GA-EP45-DS5 Lockup problem...

    I give up...

    Well Hi, never posted here before but I'm trying like crazy to find any solution for this FUBAR rig of mine.

    Long story short, this WAS my old rig

    GA-965P-DS3
    E6600 (Thermalright extreme tower cooler, supported by 120mm fan)
    EVGA 8800GT DDR3 512MB (w/ Thermalright passive cooling supported with 120mm fan)
    8GB Corsair XM2 DHX 800mhz 4-4-4-12 (2.1v)
    1x 500GB Samsung
    Corsair HX520
    Vista Ultimate 64bit

    Then I decided I wanted more and I got my self GA-EP45-DS5 and E8500 and a second 500GB Samsung (running them in mirrored RAID mode on the ICH10 controler)

    Well then the problem started, I started to get random lockups in Vista, specialy under load. The lockups got more frequent and soon I couldn't even get to the BIOS.

    The lockup is always the same, the screen freezes, and I can't do **** with my computer unless I cut the power or hold the power switch for 5-10sec, I get no errors in event viewr what so ever.

    Tested numerous settings in BIOS, got version F5, flashed to F12, nothing changed.

    Tested with number of Graphic cards and the problem was there with all cards except low power cards like Geforce 7600.

    Tested with another 1066 5-5-5-18 RAM, still the same problem

    Tested with more power full PSU, 700W Gigabyte PSU keept the computer, no exteded testing though since I couldn't have the PSU for long to test it.

    I got new EP45-DS5 from my local computer shop, the problem disapeared, I thought. Soon began again when the computer was under stress (gaming etc.), but I needed to stress the computer for 30mins at least to get a lockup.

    Got new E8500, nothing changed, still lockups after a while of gaming.

    Got new RAM (same model), still the same problem.

    Tested with another PSU, 460W standard model from Gigabyte from my server, got almost 4hours of straight gameplay no lockups.

    Got new PSU, claimed my Corsair HX520 as a fault one and got Tagan BZ 600W Piperocket series instead from my local computer store, still the same problem.

    Now I'm clueless.

    Anyone ideas are welcome?

    Any known issues with any of my parts that could lead to these strange lockups?

    regards

    Are you trying to run 8GB of ram at 1066Mhz? (or was that just the test ram?)

    If you are running 8GB of 800Mhz ram you will have to tweak the ram timings. As Vista uses ASLR it is totally unforgiving if your memory is less than perfect.

    Have you Run Memtest or Vista's memory Diagnostic.

    You could try:-

    1) Performance Enhance = standard
    2) tRFC = 70
    3) Main timings to 5-5-5-18
    4) Voltage at 2.0-2.1volts

    My ram is 8GB 800mhz rated 4-4-4-12 (4x 2GB chips)

    I'll try these settings, but I would prefer to run it at tighter timings, or maybe run it at timings you recomend and run it on faster speed, 1066mhz..

    These Corsair XM2 DHX chips are suposed to handle that easy.

    Thanks for you're reply

    Wouldn't we all.....

    Realistically running 8GB of 800Mhz memory at 1066Mhz, or at 800 Mhz with tight timings isn't likely to happen or if it were that straightforward, you probably wouldn't be posting a question......

    Even with the best suited memory, I'd be surprised if you achieved 100% stability across the board with Memtest, Prime95 & Vista and it's ASLR (Address Space Layout Randomization) etc - which will "Remind" you every boot if it finds less than perfect memory, by locking up, rebooting etc.

    Hi again

    I tried this,

    Cleared CMOS,
    1) Performance Enhance = standard
    2) tRFC = 70
    3) Main timings to 5-5-5-18
    4) Voltage at 2.0-2.1volts

    boot to MemTest86+

    System locksup after 1 min and 16 sec of running MemTest86+, no errors

    Another note wich I find a bit strange, after clear cmos and when the board was new the CPU Clock Ratio in BIOS is default set to 8 and Fine CPU Clock Ratio to +0.5, CPU Clock Ratio should be automaticly set to 9. I have Intel E8500.

    This board has been nothing but trouble for me, I have been trying to figure this out for almost 2 months with no luck, this makes my sad as I realy like Gigabytes products and my last 6 builds have been Gigabyte boards.

    Hi,

    Did a new test today, new RAM, 1x 2GB 800Mhz OCZ Value RAM.

    Lockup in MemTest86+ after 10minutes.


    anyone?

    Are you using the latest non beta bios?

    Load up the optimised defaults, save, re-enter bios and set performance enhance to standard. Test with DDR2 voltage at 1.8, 1.9 or even 2.0 volts on the new ram. Use memtest 2.11

    Also it's a bit odd you getting remnants of old bios settings. It suggests you didn't load up the defaults (and SAVE) after a bios upgrade. You may need to properly clear your cmos because of this.

    Before reading you're comment I had loaded optimized defaults in BIOS, tested with 1x 2GB RAM in slot1 (of the 8GB Corsair XM2 DHX 800mhz 4-4-4-12 (2.1v) (4x 2GB) set)

    And after 40minutes my computer hadn't lockedup.

    Installed a second 2GB RAM chip to slot3, the computer lockedup.

    Tested the second chip alone in slot1, no lockup for 40min.

    Tested with second chip in slot1 and first chip in slot3, computer locked up

    Tested with second chip in slot1 and first chip in slot2, no lockup for 40min.

    moved these two modules between slots and computer always locksup when running in dual channel mode.

    You're sugestion

    With 2GB Corsair chip in slot1 and second one in slot3 (dual channel)

    Cleared CMOS, turned of computer, unplugged from wall, shorted CMOS jumper.

    Boot, entered BIOS and loaded optimized default, save and exit.

    Boot, entered BIOS changed boot order to CD-ROM first.

    Boot to Memtest86+ v2.11, computer locksup after 2min and 30sec

    Changed DRAM Voltage to 1.9V, Boot to Memtest, computer Locksup after 2min and 30sec.

    Changed DRAM Voltage to 2.0V, Boot to Memtest, computer Locksup after 1min

    Changed DRAM Voltage to 2.1V, Boot to Memtest, computer Locksup after 35sec.


    Hope you lasted through this reading...

    And thanks again for you're time.

    Go through Steps 1,3 & 4 AFTER a load up optimised defaults and save. As the defaults usually will put Performance Enhance at Turbo, DDR2 voltage at 1.8volts and tRFC probably around 46 when you are using 4GB which is too low. tRFC should be around 56 for 4GB and 70+ for 8GB. 2GB often suits the default setup.

    Do make sure your main timings are set manually to 5-5-5-18

    With 2x 2GB modules I did another test with timings 5-5-5-18, DDR Voltage 2.1V, tRFC = 70 and Performance Enhancement = Standandar like always, and it lockedup.
