Need some advice on memory errors - 64gb of Corsair Dominator GT 1866 - Page 2

Well...that didn't take long. The sticks will also throw errors when plugged into either slot B1, C1 or D1. I can't try an individual stick in any of the "2" slots....without also having all the "1" slots filled....so I can't test individual sticks in those slots. But if the memory is throwing errors in all 4 slots that I can test individually....I think I can rule out the motherboard having a bad slot.

Guess I'll move on to testing at the SPD settings.

You should try to set VCCSA and VTTCPU first. 1.05v is the x79 default for both (1333 RAM), 1.10 is considered the de facto standard for using faster RAM.

Under the XMP auto settings, these are already 1.2 and 1.18, respectively.

They dropped to .88 and 1.04 , respectively, when I chose not to load the XMP.

wow... voltage likely isn't the issue then. Could the memory controller in the CPU be faulty?

if all 8 of your ram is experiencing errors it might very well be the mb or cpu..y dont u run the memtest in another mb...if each one passes then u know its not ram..meanwhile check the mb with a known good ram that u or ur friends have used and had no problem...also check the cpu...with so many interconnecting chips it will be very difficult to pinpoint exactly where the problem is unless u systematically check each and every component..it maybe a faulty ram controller or a single ram slot error..i had had even the video card driver problems causing all sorts of errors in memtest while doing it in windows..but when i did memtest through bios and linux it wasnt a problem..reinstalled nvidia all was good....

First few sticks I tested under the auto settings (1,333 MHz 9-9-9-24 ) also threw errors.

I think prathik7's suggestions make sense. Just difficult to do. My working box uses DDR3 memory...but its 6 slots that support up to 24gb. Not sure what it would do with an 8 GB stick. But I guess I could test the memory in the other box first...and then move it to my new box to see if that works.

Frustrating.

i know...troubleshooting is the most daunting part..atleast u got ur problems before build is complete...all the best...and dont ever compromise on quality..if u find a ram or any other component problem immediately RMA....one small problem will become a disaster in no time..especially if u plan on oc and running the pc 24/7...the QC in pc parts is dismal nowadays...

Update. Last night I ran memtest86+ in the OLD box with the OLD memory for about 9 hours and had zero errors. So what I'll do now is start doing some swapping of OLD memory and NEW memory, between the OLD box and the NEW box. I'm not 100% sure the OLD box will accept the NEW memory (8gb sticks), but we will see. In any event, I should be able to test the OLD memory in the NEW box. If that is successful it would at least eliminate some possible problem.

Will update thread with results.

Update:

The OLD memory that tested fine in the OLD box....threw errors when put in the NEW box. It threw errors on the auto settings, and also when I input the rated settings.

The NEW memory that threw errors in the NEW box....is so far testing fine in the OLD box. I won't call it done yet, but its on pass 2 with no errors so far. Although...its running at the auto settings, which came in pretty slow. I'll need to input rated settings and do it again IF it finishes without errors. But it wouldn't test without errors on either the rated settings or the auto settings when it was in the NEW box.


So help me decipher this one. Assume the NEW memory continues on and tests fine in the OLD box. What does that mean? Does that make it either the motherboard or the CPU? Are there other possibilities? I don't think it can be just a bad slot on the motherboard, since the memory throws errors in all slots. And the memory is on the supported list for this Asrock board.

What would next test step be? Put a different CPU in the motherboard?
