    Default EX58-UD4P overclock and S3

    howdy everyone -

    i continue to have problems getting my EX58-UD4P to resume properly from S3 sleep when overclocked. i am running bios F8a.

    i had bclk=166 with x18 cpu multiplier going for a while, but then i found after a power cycle, the machine would not POST. i reduced to 150Mhz/x20 and that worked for a while, but after a power failure last night the machine started locking up 100% of the time coming out of S3. i went back to bclk=133Mhz and x20 and it's fine again, no lockups out of S3.

    here is what i originally had when running bclk=166Mhz.

    when i went down to 150Mhz i simply set the cpu multiplier back to x20.

    there are so many voltages and multipliers i have no idea which ones are relevant to this problem.

    does anyone have a bios template for a EX58-UD4P giving 3GHz for the CPU and near 1333MHz for the dram? that's all i want, and judging from what i've read here this should be a very achievable overclock. or, should i be using a newer BIOS? i've heard that F9a has some serious problems...


    thanks for any help.

    I don't see any glaring problems, and your right that 3Ghz should be no problem at all. I would up the memory voltage to 1.64-1.66v. The 1.66v setting gives a warning that DRAM voltage may be too high, but the actual value will be 1.65v, which is what most DDR3 ram is specced at. Resuming does tax the ram quite a bit so that may be the culprit. Also run some memory tests like memtest86+ and Memtest 3.8 which are both linked to in this thread: http://forums.tweaktown.com/f69/late...y-tools-30530/

    Also, the F8a BIOS should not have any problems resuming. However, at least upgrade to the non-beta F8 BIOS from Gigabyte's official page. The F8 BIOS is the final version while F8a was the beta, so F8 is newer than F8a. What problems are you referring to in F9a? I am running F9a with no problems.

    thanks for the reply. i'll try increasing the dram voltage. however, when i was at 150Mhz the memory multiplier was still x8, so the memory speed was 1200MHz. i would think the lower frequency should allow me to run a lower dram voltage, but maybe the difference between 1200 and 1333 is just not that significant.

    my cpu Vcore is set to Auto, and i've heard that this is bad for overclocking in general. do you have any reccomendations for Vcore on a C0 920 @ 3GHz?

    shoot... looking at what i wrote, now i'm wondering if i filled out my template right... since 1.5V is the stock voltage for DDR3, that can't be right - i know i boosted the voltage some, but since i'm typing from the machine in question (and its not running windows) i cant check without rebooting.

    somehow i thought that F8a was newer than F8, but i guess if "a" stands for alpha then what you say makes sense.

    i think lsdmeasap had said that in F9a after resume from S3 there are a bunch of dram-related parameters that get clobbered. i think that's somewhere in the "gigabyte new bios" thread.

    At 3Ghz, leave the CPU Vcore setting to NORMAL to keep it at stock. There should be no problem getting to 3Ghz at stock voltage, even if you had stock cooling (see my sig for my own overclock).

    Exactly. F8 is newer.

    Heh, I discovered this and told LSDMEASAP a while back in this thread:http://forums.tweaktown.com/f69/ex58...-issues-32177/

    I can't remember if F8a showed this, I have never tried F8 myself. It's also not a big deal, just a simple reporting error, no way the RAM is working at CAS 4. Hasn't affected system stability at all. When you get S3 resume working on F8a or F8, see if it happens for you.

    ok, i'm going to set Vcore to NORMAL. should that be done for any other voltages as well?

    you are right, the CL thing has to be a reporting error.

    to be quite honest, i had been using F9a and had very good success with wake from S3 while overclocked on that bios. however, i was also getting an intermittent mprime error on that bios and so i reverted back. however, i think i get that error even on F8a, and i think perhaps i do have a bad memory module... memtest86+ is totally fine (in fact that's how i discovered i had to raise Vdimm - it was totally failing before bumping Vdimm) but some memory address or other is giving problems at full load.

    so i might try upgrading to F9a again. first i'll try the CPU at NORMAL and raise Vdimm a little bit more though.

    thanks for the help.

    I have all the following voltages set to NORMAL so I know they don't get set to something ridiculous as I overclock. DRAM is set to 1.66v.

    </pre>
    I would also try raising the QPI to 1.22-1.24v if the other voltages don't fix it.

    okay. as soon as this stupid backup is finished running i'm going to go tweak my bios. hopefully i can get right. it doesnt feel right to have gone from a 3GHz Q6600 to a 2.66GHZ i7 :)

    Lol, I can understand that, although even at 2.66Ghz its better at many things :)

    Keep us posted on how it goes. I'm thinking its just memory/QPI voltage, no other reason I can see why a modest overclock to 3Ghz wouldn't work. After that starts working I think you can aim for at least 3.2Ghz-3.4Ghz.

    okay, i went into the bios and changed every last voltage i could find to NORMAL, with the exception of QPI and Vdimm (1.22 and 1.64V respectively). on a whim i set bclk to 166, cpu to x20 and memory to x8, so i've got 3.33GHz for the cpu and 1333MHz for the memory.

    it POSTed fine, and i've slept/woken it about 10 times while the machine was fully loaded with 8 threads of mprime. peak core temperature at load is down about 4C to 70C so i guess this must have worked. however, i've had it in this state before, seemingly working fine, and then rebooted it to find it would no longer POST.

    the other thing is that mprime seems to run happily forever until one sleep/wake cycle, and after that it fails very soon after waking up. if i quit mprime and start again, it fails again. so its almost like something is not set up right after resume from S3.

    i think i should at least upgrade to F8 and see if it keeps doing this.

    anyway, thanks a lot for the help. only time will tell if setting everything to NORMAL has fixed the problem, but i feel pretty good about it.

    bah, i rebooted it and it would not POST. i went in and set the dimm voltage to 1.66V, and it POSTed okay and booted. still seems to sleep/wake okay. i guess i can live with the occasional POST error, i never actually reboot the machine (provided S3 works :)

    at this point maybe i'll wait for F9 and then upgrade. last time i made changes to the bios i ended up in a situation where i could not downgrade until i reverted to the factory back-up bios (F2) and that was a real hassle.
