Memory_Management BSOD using CMZ16GX3M4X1866C9 at 1866 (stock)

Hi guys,

I've recently built my first computer and have invested in two sets of CMZ16GX3M4X1866C9 (DDR3 1866 4x4gb) RAM.

 

My ASUS Sabertooth X79 is reporting each individual stick's speed as 1333 and when I try to manually set it to 1800 in the BIOS, Windows 8 gives me a BSOD suggesting I search for MEMORY_MANAGEMENT.

 

(I did run Memtest86+ via USB overnight, not sure if it's supposed to just stop when finished or restart and make a log of the results, as I was at the Windows 8 log-in screen when I got to my computer :sigh!:)

 

Any help would be greatly appreciated!

Thank you

Hi guys,

...two sets of CMZ16GX3M4X1866C9 (DDR3 1866 4x4gb) RAM.

please try one matched pair by themselves at a time from the same package.

combining 2 sets of ram even the same part# is not supported, suggested or recommended

 

with that being said, flash your bios to the newest and try 1 stick at a time and run memtest for a few complete loops just to make sure one is not failing.

 

other than that, mixing/combining 2 kits is not ideal at all.

oh, memtest will not stop running, something rebooted you during the night.

Thanks for the replies,

Not overclocking anything, I had flashed the BIOS and saw it say 1333, so I changed the target value to 1866 (only change I made).

 

In BIOS, all sticks read as 1333:

After switching to 1866, memtest reports all but one stick saying 0mb, yet attempts to test all 32Gb (and fails):

Just changing the frequency isn't going to work and the memory will fail memtest as it is now.

 

Check your owners manual for the XMP setting. It will be under tha advanced tab in the BIOS. As i said it will also adjust other neccessary system voltages and set the timings for you too.,

 

But,All memory will show as 1333mhz until other wise changed.

 

If that still does not work, then please use Synthohols suggestion of testing each kit on its own with XMP enabled .Depending on the results of that we can go from there.

Thanks for the reply, I've read through the manual and switched to XMP.

OS seems to run fine now, no BSOD!

Unfortunately, both Windows 7 & Memtest86+ are reporting 30gb installed.

The following screenshots are in chronological order:

Should I try something else, or would the next step be an RMA?

After triple checking my seating and getting the same results, I tested one stick at a time, and each stick worked fine w/ RAMtest86+. :thinking:

 

So then I decided to try and re-arrange the seating/order (since they're all the same ram), and I don't know if there was some dirt/dust that came out while removing the sticks, but it seems to work fine now! 32gb across the board, with no sticks listed as "abnormal" :bigeyes:

Thank you, everybody, for your support and replies!

Glad to see you got it solved.

 

That would have been my next suggestions was to test each stick on it's own to see if there was a particular stick that was only detecting half of what it should be. But sometimes just reseating the memory will solve things as in your case.
