x58 BSOD after getting new RAM - Machine Check Exception

chickadee · 19 Jun 2016 at 06:33

So my system has been running fine for years with no problems but recently I upgraded the ram. Here is my specs:

Xeon X5660 - stock
Gigabyte UD5
MSI 780
Samsung 850
3x2gb Kingston

And then I purchased a 12gb kit of Corsair Dominator, installed it alongside my Kingston ram and now have 18gb, everything is working fine but every maybe 10th reboot i get a BSOD Machine Check Exception.

Any ideas? my guess is because I have all 6 slots populated.

Run memtest86+ overnight and see if the RAM is faulty. That would be the first thing on my task list.

When you use all 6 sticks there's a chance QPI doesn't get enough power.
Check with AIDA if in the memory XMP profile there's anything about Memory controller voltage. Mine 1600mhz Kingston Genesis, saying 1.4v for Memory controller. I know it's bit higher than Intel specs,, so i set QPI VTT to 1.355. No memory issues.

So your running 2 different kits at the same time, asking for trouble really, ditch the kingstons and just use the 12GB corsair kit.

It's probably a power issue. Put the rams at 1333 and reduce voltage. Gotta help.

As above, it's because you've occupied all 6 slots. Remove the Kingston stuff, and just run the 12GB.

If you want to keep all the RAM, double check the voltages and speeds match, and remove or modify any overclocks you've got

All my ram is running 1333mhz and 1.5v, no XMP enabled as it never worked with my Xeon.

The thing thats weird is i have never had a BSOD once im in windows, its only when doing a fresh startup maybe 1/10th of the time.

Besides qpi also try adding a touch more vcore, due to the extra strain it may well need it.
