    Default GA-EP45-DS3R unstable after sending to S3(STR) sleep state (FIXED)

    I have a GA-EP45-DS3R mainboard, which is unstable (random bluescreens) after waking it up from S3(STR) sleep state. The bluescreens show up right after return or about 1-2min after that. At times the system won't even return from sleep state.

    My system (less than 4 weeks old).

    CPU: Intel Core 2 Duo E8400, Dual Core, 3.0 GHz, 6MB
    MB: Gigabyte GA-EP45-DS3R, Intel P45, FSB 1600
    GPU: Gigabyte 9600GT Turbo Force 512MB, PCI-E x16
    RAM: 2x Kingston HyperX, 2x1GB, DDR2-800, CL4, KHX6400D2LLK2/2G (that makes 4x1GB in total)
    HDD: Seagate Barracuda 7200.11, 7200rpm, 32MB, 500GB
    PSU: Be Quiet Dark Power BQT P7-PRO-550W, Pro Edition
    OS: Microsoft Windows Vista Business x64 SP1
    BIOS: Updated to the latest version F8. Default settings (not overclocked), RAM at 2.0V (as specified by Kingston), CPU Vcore 1.25V.

    Latest Drivers for the mainboard and graphics card.

    The system runs perfectly stable after fresh boot. Prime95 stress test stable (CPU). FurMark stress test stable (GPU). Memtest86+ stable with complete 4GB RAM at 4-4-4-12 timings and 2.0V.

    Replaced the PSU with a different one, without effect.

    Changed RAM timings to the 4-4-4-12 specified by Kingston, without effect. Unstable after waking from sleep even with 5-5-5-15 timings. Direct from a fresh boot both are timings are stable.

    Removed 2GB of RAM (2GB left). Tested once in dual channel and single channel setup, still unstable after return from S3(STR) sleep.

    With only 1GB of RAM it seems to be stable (so far), even after return from sleep.

    All the stability problems after return from sleep state disappear if I change the ACPI suspend type from S3(STR) to S1(POS). But I need it to be stable with S3(STR) as well.

    All the temps are in the green range. CPU core temps always 30C or more from TJ max, graphics card with an additional 120mm fan around 42C. Problems remain the same with open case (additional cool air). The case itself runs with two 120mm case fans. Seems not to be a temp issue, since all the stress tests (CPU and GPU at the same time with FurMark and Prime95) run stable, if the PC comes from a fresh boot and not from sleep state.

    Some times after a crash right while returning from S3 sleep state, the PC goes into an infinite reboot loop. Only removing the 230V power ends the loop and lets the PC boot normal again.

    The problem is not influenced by the FSB. I tried both 333MHz (=1333Mhz)(default) and 400MHz (=1600Mhz), with RAM running once at 665 Mhz and 800 MHz.

    Somehow this looks to me like a problem with the mainboard. Any ideas how to get the sleep mode running stable? Or what else to test?

    Edit: Found a thread with someone having the exact same issues. The only things in common with his hardware:

    MB: Gigabyte GA-P45-DS3L (almost the same, DS3L vs. DS3R).
    OS: Vista x64 SP1
    HDD: Seagate 500GB SATA2 7200 32mb

    Vista x64 BSODs on Resume from S3 Standby - Vista Forums

    No solution there yet. Either it is a problem with Gigabyte GA-P45-DS3 boards or Vista x64.

    Similar problems can be found here as well

    Blue Screen on Resume from S3 - new Build Giga-byte EP45 DS3 - Australian Media Center Community

    again with a Gigabyte GA-P45-DS3* board and Vista x64 SP1.

    Some more problems which look very similar

    AnandTech - Gigabyte EP45-DS3R - S3 Standby Mode

    ---

    FIXED: The problems described in this thread for the GA-EP45-DS3R rev. 1.0 board can be fixed with updating the BIOS to version F10. GA-EP45-DS3R (rev. 1.0) BIOS F10 (Fixed Vista S3 resume sometimes failed)

    I also am experiencing this exact same issue with an GA-EP45-DS3R both with F6 or F8 bios. I have updated all my drivers, upped my RAM voltages, and applied windows patches. Everything is currently running at stock, and temperatures are not an issue. I have successfully returned from sleep one time with countless other crashes within 0-5 minutes. Furthermore, running a memory intensive app seems to hasten the crash.

    The specs of my system are as follows:
    CPU: Intel Core 2 Quad Q6600
    MB: Gigabyte GA-EP45-DS3R
    GPU: ATI Radeon HD 4870
    RAM: 2x Corsair 2GB DDR2-800 CL5
    HDD: Western Digital Caviar 500GB
    PSU: Corsaid 520W
    OS: Windows Vista 64-bit Home Premium
    BIOS: Currently F8 (have tried F6 too)

    As you may have noticed, the only thing in common with our systems is the motherboard! I have had no stability issues whatsoever outside of returning from sleep mode. Apart from the overly annoying placement of the RAM slots on the motherboard, I haven't experienced any other issues with the motherboard.

    A solution to this would be nice, but I fear the only solution would be a bios update or perhaps different RAM. I've noticed that neither of our RAM's are listed on gigabyte's pathetic list of supported RAM.

    Do you guys have External USB hard drives? If not please disable "Legacy USB Storage Detect" in the integrated Periphals section of the BIOS, this often helps with many issues. Also Disable USB mouse/Keyboard if you are not using those. If you are then leave them enabled, it is not as much of a issue as the USB Storage Detect is

    Then please add +.1-.2 to MCH Core and see if this helps any

    I tried already +.1, +.16 and +.2 MCH Core, without influence.

    I have an external USB Harddisk (Western Digital My Book 1TB Office Edition), which crashes the pc during booting of the bios. It did this on a 5 year old MSI mainboard and again on this GA-EP45-DS3R. It has not been a problem on some other Gigabyte mainboards. And disabling Legacy USB Storage Detect solved the problem already. Still, thx for the hint. Anyway for the S3 sleep and resume tests I had it always unplugged.

    I use an USB keyboard and mouse, and I need to keep those options enabled. Otherwise I don't have any keyboard support on the Vista advanced boot options screen (the one that shows up after a Vista crash right before booting).

    So far it seems to be either a hardware problem of the mainboard, a bug in the bios or a software problem of Vista.

    Well it has been a known issue in P35 boards, But they have released recently BIOS fix that corrects it. So maybe The P45 boards will soon have a BIOS update to fix it as well.

    Do you have your ram DDR2 Voltage Manually set to 2.1V? If not you should, and you should also manually set trfc to 52-62 for 4x1GB

    It is a BIOS issue though really, but often times getting ram tweaked or other BIOS settings adjusted properly helps. In the end though you may need to wait on a BIOS update to fix the issue

    I have set the DDR2 voltage to 2.04V which yields 2.0V idle on the RAM. Kingston specified 2.0V.

    Just tried setting it to 2.1V and trfc to 62, whithout influence. Vista returns from S3 and about two seconds after starting Prime95 Blend Test I get the BSOD.

    So... If you do not do a resume from S3 does Prime95 Not BSOD?

    Are you running blend on Prime95? Just have to ask incase you are unsure (Some people do not know so I thought I better ask) because if you are not then it would be more of a CPU issue.

    And does it matter how long you wait after resuming before running Prime95 if it BSOD's or not? And really if this is the only issue you have with S3 then you are doing well, most cannot get it to resume. So you may just be stuck not running prime95 after a resume until a BIOS update is put out for your board. Not such a Big deal if everything else works fine I would think.

    Not trying to "Blow You Off" or anything with that comment at all, just saying that you are lucky and that seems like something I would personally overlook for a while if it is the only issue you have with S3

    But like I said it was a KNOWN issue with P35 boards and JUST recently fixed with BIOS updates, so maybe the P45 boards shipped out with the same issue and a BIOS fix has not yet been implemented for P45 boards.

    If Vista runs from a fresh boot, then Prime95 does not cause any bluescreen. I have run it four hours without any unstability or even rounding errors. So the CPU and voltage should be fine.

    If I wait a bit longer to start Prime95, then Vista crashes just during any other random operation (but again of course, this happens only after resume from S3 sleep). The only reason I start a Prime95 Blend Test right after return from S3 is to see, if I could expect a random crash during any operation, or if the pc runs stable. Sometimes it can take a few minutes for Prime95 as well to actually cause a BSOD. So in its current form S3 sleep is of no use to me.

    For the moment I have switched the BIOS back to S1 sleep, which is not that great, but at least it is stable.

    If it was a known issue with P35 boards, then it is perhaps a design problem with the P45 as well, and not a defect of my board (which I feared most). My old MSI VIA mainboard caused rare bit corruption (like 1 Bit in 1GB) when copying files from one drive to another. Which I found out only after 1 year of using it, that it is actually the board doing it. So it is important to me, that I can actually trust the MB, and that there are not any random crashes or the like. If the problem is really limited to S3 not working properly, then it is not such a big problem for me.

    Maybe I need to contact Gigabyte directly to see, if there is any known problem.

    Anyway, good to know about the P35 problems.

    Ya, it is likely a design/BIOS flaw and not just your board in particular at all.

    Good luck on getting a real reply about it all though, Hopefully soon you will see a BIOS update for your board. I just saw one for mine the other day, but I don't use it anyway so no big deal to me

    Somewhat ironic that a board which brags about its power saving features can't use S3. Or maybe that's just to influence you to shut your pc down completely.

    Thanks for the responses and the op's efforts to fix the problem, now I just have to decide if no S3 and having to remove my graphics card anytime I want to touch my RAM is worth RMA'ing an otherwise stable board. And btw, my crucial memory is working just fine, even at the default 1.8v which is below the memory specs.
