RAM causing system freezing?

[phillcall]

I have been having problems with my system since i built it, in the sense that it randomly freezes (usually when watching youtube or netflix etc). It forces me to hold power button down to switch off, which gives me an event 41 kernal power error in event log.

 

I think it could be down to the ram but im unsure of how to test it without going out and buying a new set. I fear that the Crucial ballistix tactical tracer 1866 ram is not compatible with the Haswell cpu? It automatically shows in my bios as 1333 which is weird also.

 

I have ran a windows memory test with no problems found.

 

 

system spec is:

 

CPU: Intel Core i7-4770K

CPU Cooler: Corsair H100i

Motherboard: Asus Sabertooth Z87

 

Graphics card: EVGA GTX 770 SC ACX

Memory: 2x Crucial Ballistix Tactical Tracer 8GB (2 x 4GB) DDR3-1866

SSD: Samsung 840 Pro

Storage: Western Digital Black 2TB 7200RPM

Power Supply: Corsair AX760

 

Sound Card: Asus Xonar STX PCie

 

Any recommendations to narrow the issue down would be much appreciated!

Try using one stick in all slots, then two in different slots. If you can, run Memtest.

Every ram goes to 1333mhz whitout XMP or OC, you should try to run Memtest, but i do not think that it is your RAM, but you should still try to run it.

Yeah, intel decided to default all RAM to 1333MHz, but it will have probably come with an XMP profile on it. Go into your BIOS and on the AI tweaker select memory config and on XMP profile select profile 1. (Might not be quite the right path - doing it from memory from my sabertooth z77).

Anyway, back on topic: When it freezes, does the cursor and all audio freeze or just the windows? How are your temps? What happens if you leave it for, say, 15 minutes (yes, I know that means finding something else to do, but it's a necessary evil :P)?

Just in case this helps anyone in the future the solution to my problem was a RMA on my graphics card. Additional to the original problems, I was also experiencing power shorts when i connected USB's into the motherboard (my power supply would shut down to protect my other pc parts)

 

New graphics card and everything has been working perfectly since (5+ months)
