I have just assembled my new PC:
- mainboard: Gigabyte X79-UD3 (bios version F9)
- cpu: i7 3820
- memory: Patriot Viper Xtreme Series, Division 4 Edition DDR3 16GB (4 x 4GB) 1866MHz PXQ316G1866ELQK
-PSU - Be-quite dark power 1200W
- MSI Gf 560Ti
And I have problems with memory.
When I turn on XMP profile in bios I got random bsod and stress test software fails (Prime95, super-pi, intelburntest)
When I turn off XMP and use standard settings (666MHz, 9-9-11-24) tests don't fail and system is stable.
Run memtest+ for about 9h and there where no memory errors.
Using XMP profile + DRAM voltage at 1.75 seems to work.
Is it save or should I try different voltage settings?
System is not OC.

Hi there,
Having checked the specification for your RAM Modules they should run at 1.65V and I would try pulling the RAM voltage back to this and see if the system remains stable.

Hi,
I tried at 1.65 system is unstable BSOD and prime fails after 1-2 tests
The only viable option is to set DRAM voltage to 1.75, tried increasing vtt (to 1.2), imc (to 1.4) without any luck.

If you are running XMP enabled, 1.65v @ 9-11-9-27 timings and cannot get 1866 stable, you
need to contact manufacturer's tech support. My guess is you have a bad stick.

BigDave_56 you are right, just checked another (3rd package of memory :)) and it works fine at 1.65, although at 9-11-11.
I have also contacted patriot support (via forums) and increasing DRAM voltage above 1.70 it's dangerous.
2 box of memory went to RMA, hope the new one will be fine :)
