    Sorry, but can't test that. My Gigabyte is at my server which is colocated and quite hard to access.

    Running perl script that makes an array size of 6-7G in memory didn't make the errors go away.

    What I really need is some genuinely bad ECC memory, so I could make sure that real problems are being logged, and then check to see that the same logs remain silent with good ECC memory...
    Sorry, still no reply from my guy I emailed yesterday, but on the 4/5 the contact I speak with almost daily will be back in the office so I should for sure know something for you guys by next week.

    Sorry about the delay on this, so many posts here this got buried and I forgot all about it

    To check logs in windows you would use the event viewer, that is in Administrative tools, event Viewer. You may need to customize the start menu and enable the Administrative folder as it is not on by default. Now, I am not sure where in event viewer you would find the errors listed, but I would suspect in the "Windows logs" Section then within the "Applications or Systems" Sections.

    You may also bring it up by typing eventvwr.msc in the run box

    I'll keep you informed on any info I get passed along to me on this issue, please do not let this get buried again and I will try to keep asking for you guys

    No messages about memory errors there, although I would feel more confident if I knew for sure that real memory errors would be reported.

    By the way, if you are talking to someone about this issue, could I put in a wish list request? I am not aware of any (free) memory testing programs that know how to disable EDAC mode for the X38/X48 chipsets, which means that they may report good memory when in fact one bit is bad and the ECC memory is simply allowing the error to be corrected. It would be wonderful if the BIOS allowed me to turn EDAC mode on or off, so I could turn it off when running a memory tester and turn it on for normal operation of the computer...

    Ya, sorry I am not sure IF errors would be reported in windows in that section or anywhere, I just assumed that would be where you find them if they are reported.

    Can you ask your memory manufacturer, they for sure should be able to tell you if and where error reports would be in windows.

    Yes, I will ask about that for you guys as well. Hopefully will have some answers on these issues for you this week. Of course we will have to wait on my contact to get back to me, then for the BIOS Engineers to get back to him, then back to us. So it may take several days, but I will find out what they have to say for sure.

    And yes, I will ask if they can add an EDAC On/Off mode in a BIOS for you, if that is possible they will let me know.

    Sorry again for the long wait on this issue!! Hopefully we will get something figured out on this for you this week

    OK, I tried asking Kingston (specifically about where Windows would report correctable memory errors) and got back the reply:
    Please confirm with motherboard manufacturer to see where you can check the log. Because different motherboard manufacturers will set the error log in the different place according to their design.
    I am guessing that Kingston are talking about some kind of error event log maintained in NVRAM on some motherboards? Otherwise I can't see that the motherboard could control where Microsoft stored the errors?! Anyway, I pass on the reply in case it makes more sense to anyone else than it does to me...

    I feel like I am pestering, and I understand that it is not your fault if Gigabyte takes a long time to reply to you, but is it time to unbury this thread again?

    Lsdmeasap has been offline (or at least not active here) for a few days. He has a satalite net connection, and has had problems with it in the past.

    He may just be on holiday though, nobody knows.

    He has a system of replying in sequence to unread posts and I'm sure he'll post here when he returns.

    Unfortunately I know nothing about ECC RAM etc, so I can't help there. Just thought you'd apreciate hearing that you're not being ignored.

    Sorry for the late reply here guys!! I took on double shifts this week at work to try to catch up on some bills, otherwise things were about to get very hairy around here.

    I have gotten a reply back from my contact at Gigabyte, sorry it took so long he was out of the office the last few weeks, and again last week. He said he has passed this info along to the BIOS engineers and they ARE looking into it.

    He said he will be back in the office Monday so I should be a more in depth reply this week once he has got back in the office and caught up with things. Hopefully the BIOS guys will have something for you all by then

    OK guys, sorry for the very long and overdue wait!!

    The BIOS engineers would like you to test this beta BIOS with NON ECC Ram, and then with ECC Ram as well. They have removed ECC Support because they think the EADC errors may be caused by other hardware or issues.

    Here is the Beta BIOS they would like you to test, hopefully you guys can download from this site without issue. If you have trouble downloading let me know and tell me another preferred site you would like the file hosted at.
    MEGAUPLOAD - The leading online storage and file delivery service

    Or
    http://www.filedropper.com/x48ds4-f2x_1

    So both ECC and NON ECC Ram should not give you EADC errors now, if you do still get them then they need to further test things.

    If you do still get them let me know, I will pass it along and they will get back to me on it.

    Thanks guys, and again so sorry for the long wait in getting something moving on this.

    OK, done. Here are the results:

    1. BIOS F3c with nonECC RAM: no EDAC errors reported
    2. BIOS F3c with ECC RAM: constant EDAC errors reported
    3. BIOS F3c with ECC RAM but after running a cycle of memtest86+: no EDAC errors reported
    4. BIOS F2x with nonECC RAM: no EDAC errors reported
    5. BIOS F2x with ECC RAM: no EDAC errors reported

    So the new BIOS has indeed changed the observed behavior: there are now no EDAC errors being reported when using ECC memory.

    However, I gather from your post that the F2x BIOS is not a fix that makes EDAC work properly; it is just that EDAC is disabled and so it makes no difference whether I use ECC or non-ECC memory with it?
