GZ-Z77X-UD5H Random freezing and shutdowns.

[Neal Stuntz]

My system is randomly freezing and shutting down. I have tried 2x Corsair Vengeance 1600mhz 8GB ram sets (CMZ8GX3M2A1600C9B) and G.Skill Ripjaw F3-17000CL9D-9GBXM. I am not overclocking and I am using the stock CPU fan.

GA-Z77X-UD5H
i7 3770k w/ stock cooling not OC'd
16GB RAM 2x Corsair Vengeance 1600mhz 8GB ram sets (CMZ8GX3M2A1600C9B)
eVGA GTX 260 gpu
Antec 550watt PSU
Intel 80GB SSD (310 series)

Everything but mobo/cpu/ram was pulled from my working Q6600 build. I have put the Q6600 parts back in and no issues.

System will freeze in the BIOS, W7, linux, anywhere.

Temperatures are all within range and I have seen no errors in any event logs.


Thanks for your help

setting xmp for the memory? what dram and qpi/vtt voltage are you using?

[Neal Stuntz]

I am running Optimized Defaults -- I will get the exact settings for you in a few minutes.

IDK but for some reason those two kits of ram don't run together @1600Mhz (in my exp). For others maybe. Have you just tried to run them at 1333Mhz with XMP disabled to see if you get stability? You won't see any real word difference @1333Mhz except benchmarking. That's what I had to do to get my X68 stable running 16Gb of that ram.

Let us know how it goes...

[Neal Stuntz]

I am not running the 2 kits together. just one or the other. I started with the gskills and replaced those with the corsair set for testing purposes. I am running the corsair at 1333mhz right now.

Thanks again for any help!

Have you tried running Prime95?

[Neal Stuntz]

Yes I am able to run Prime95 for hours on end. It is totally random when this box freezes...I'll change some settings and think it's running great for hours -- then leave it on overnight or while i'm at work and it's turned off when I get home. Then I experience random issues for a few boots and then it starts working fine for a bit.

I have been watching some video the past hour or so and I am also noticing that every once in awhile the audio is freezing for a 1/2 second or so. Using the on board audio.

Sounds like you're getting latency spikes on the audio.
