My custom built PC started to randomly shut off after upgrading RAM.
System specs:
MOBO: GIGABYTE GA-H81M-S2PV Rev 3.0
CPU: Intel Core i5-4570 @ 3.20 GHz
CPU Cooler: Intel stock CPU cooler
GPU: Intel HD Graphics 4600 ( planning to upgrade to mid-range Gefore GTX )
PSU: Unbranded generic 500W ( planning to upgrade to branded 600W )
OS: Windows 7 Ultimate 64-bit Service Pack 1
RAM before upgrading - Kingston DDR3 1333MHz 4GB 9-9-9-24 Double-sided DIMM ( KVR1333D3N9/4G )
Before upgrading RAM, I had no problems so far.
As I wanted to upgrade RAM to 8GB, I added another 4GB stick of DDR3 1600 MHz.
Kingston DDR3 1600MHz 11-11-11-28 Single-sided DIMM ( KVR16N11S8/4 )
I added this 1600MHz stick because, I thought to manually OC 1333MHz RAM and run both in 1600MHz dual channel.
These two sticks POST with no problems even after OCing to 1600MHz.
But the problem is, when I try to play GTA IV or GTA V in very low settings, the game starts with no problems, and after some time ( after 30 seconds - 1 hour ), the computer shuts itself off, even without shutting down the OS, like someone pulled the power cord. Then, it starts back and POSTs.
Not just when playing games, this problem occurs very rarely on normal usage.
What I tried:
I monitored CPU temperatures with MSI Afterburner and they're fine. ( Idle at 40 - 45C, Load at 65 - 75C )
I tested both memory sticks individually with MemTest86 (4 passes) with no errors at all.
I tested both in dual channel ( 1600 downclocked to 1333 ) and still no errors at all.
But when I test both in dual channel ( 1333 OC to 1600 ), MemTest86 gives a warning at Hammer Test.
Note: Your RAM may be vulnerable to high frequency row hammer bit flips. However the conditions needed to induce these errors occur only very rarely in normal PC usage, and so this should not be of concern to most users.
What can be the problem? What's preventing these two sticks from nicely running together?
