Hello ,
Recently i decided to upgrade to Windows 10 and i am experiencing a weird issue , i have random freezes - lockups mostly (99%) on gaming. On dr debug led i get b7 error (memmory related). So here what i have done so far
Checked for windows corrupted files- fixed.
Uninstalled-installed M/B-GPU drivers.
Updated to latest BIOS.
Checked for bended CPU pins - no problem.
Intel Burn Test 10 passes (very high) 2 times - no errors
Memtest 2 passes - no errors.
Hard disk test - no error.
CPU temps: Below 70C with 4.2 OC

My rest of my configuration is:
CPU: Intel i7 5820k
GPU:Gigabyte GeForce Gtx780 Ghz Edition
PSU: Corsair 860i
SSD: Samsung Evo 840 512Gb
HDD:Toshiba 2TB
Sound Card:Creative Soundblaster Zx
Cooling:Corsair H110i GT
Case: NZXT H440

Once i had windows 8.1 pro installed on my system with the same configuration had no such issues at all...
The only thing that i have not done yet is a clean install of Win 10...

Same issue occurs with each stick? Which version on memtest did you use?

Hello ,

I downloaded this one from here http://www.memtest.org/
I didn't run individual dimm test , i think that i can't boot the system with only one stick on board . I tested it with all four with 2 successful passes.

Yes, you can, that is also how you can find out if one stick is performing differently if it is defective.
