    Default EP45-DS3R Memory voltage problem

    Hey.

    I have the OCZ Reaper 1066MHz 4G Kit 5-5-5-18
    (
    OCZ2RPR10664GK) x2 and im not able to run em on 2.1v...

    Whenever i change from 1.8 to 2.1v in bios it will fail to post a few times, then boot normally, and upon entering bios i will get the message box that it has reverted settings..

    Sooo, any help would be appreciated, im seriously tired of this now..

    Oh yeah, i got the F7 bios (was the newest last time i checked, although i see they have added more memory fixes now..)
    Is there a way to know if any of the BIOSes fixes voltage, or if any of the fixes are for my specific ram?

    Thanks for any help. (tried sending a mail to gigabyte support but have yet to get an answer..)

    Please post your full specs, and what CPU speed you are running. is that 2x2 or 4x1 ram?

    Yeap, Anytime.

    I may not be around till 11 PM or so tonight. So if you feel froggy before I get back, what I would suggest you add for sure is some MCH voltage and manually set trfc to 52-62, then set your DDR2 Voltage to 2.1

    If you are not changing anything else (Like trying to also overclock at the same time as this voltage change to 2.1) then you should have no issues.

    4GB just normally needs at least +.1 sometimes more on the MCH Core, and if trfc is too low also it wont boot.

    Also be sure Both Static tRead Values match and that they are not too low, 7-9 will likely be fine, 6 will likely not

    Good luck, Ill see ya tonight if you are around then

    Filled in with my settings in ITALIC, aswell as some comments.. :)

    Looking forward to your reply mate..

    -nem
    EDIT:
    Im not looking to overclock the rig or anything, i just want the ram to be stable, as it is now on 1.8V i cant even run memtest without it freezing/throwing out a bucketload of errors.. Although my system is stable, sort of.. Had a few hard crashes but i recon they will vanish once my voltage is right..

    You are going to HAVE TO change things from AUTO. It is not overclocking at all, just tightening the ram timings up. Or getting them right, AUTO Changes often from what you see on the left in the BIOS (That is just what is used right at that moment)

    I will write you a more in depth answer when I get home tonight, just popped in to check my email and check on things here for a second.

    Ok mate, thanks for the reply.
    I will try this when i get home, but im curious as to what the settings:

    Dimm1 Clock Skew Control...............:[-500ps] WHATS THIS?
    Dimm2 Clock Skew Control...............:[-400ps] AND THIS? (different on channel B compared to channel A...And these are default settings)


    Why they are different from channel A.. I recon its supposed to be that way tho ;)


    So anyways, im in norway, europe, and i get home from work in another 7ish hours. I will try your recommended settings when i get home and see if i cant make it to post ;) Thanks again mate!

    Default Re: EP45-DS3R Memory voltage problem

    I am not so sure about those skew values, best to leave on AUTO. And yeah they would be different as they are a different physical distance from the CPU/NB and that is what it addresses

    Do you have your ram plugged into the correct slots? 1 +3 or 2 + 4?

    If not please fix that. If so then that may be why A is different then B, only one set of ram installed?

    Default Re: EP45-DS3R Memory voltage problem

    Both sets are installed in their corresponding slots (1,3 and 2,4) and the skew are set to this value by default, and not on AUTO. I didnt want to touch em, but then again im feeling kinda newb to this BIOS business..

    I know how to get a pc up and running, and my knowledge has been enough in the past, but now im here getting some advice from you so i hope i learn something.. :)

    I will fiddle around with it when i get home, ill first try the settings you gave me. And after that i will try setting this skew to AUTO and see if that makes any changes..

    Ok, Yeah that sounds like the best way to test. I dont have P45 yet so I am not sure, still on P35 here and I do not have any of those options to learn about.

    I have wrote a little on skews in the memory guide, but none on those specific ones

    Good luck with your venture, and post back and let me know how it goes
