GZ-Z77X-UD5H Random freezing and shutdowns.

My cousin was able to fix a crash issue on his GZ-Z77X-UD5H by using the High Definition Audio Driver from realtek's website (not Gigabyte's):

I have been up and running for over 12 hours using BLCK 100.1.

Re: GZ-Z77X-UD5H Random freezing and shutdowns.

After downloading the latest Realtek audio drivers & setting the CPU/PCIe Base Clock to 100.1, I've been "stable" for almost a full day without a freeze. However, a LinX test always fails after approximately the 12 minute & 30 second mark. Has anybody else with the same mobo ran a LinX test?

I haven't tried the LinX test but I'll give it a shot right now. What settings did you use?

usually cpu voltage or qpi/vtt voltage not enough if linx is failing,also when the blck is adjusted for whatever reason you usually need a touch more qpi/vtt voltage to compensate,thats prob why it was freezing? not sure on ib but for sb 1.2v was the recommended safe limit for qpi/vtt,you would need two or three clicks more than stock imo maybe slightly more but not 1.2v

Just the defaults. 64bit / 8 threads / Normal Priority / 4 / 15500 / 5

None - "External Applications"

i7 3770k
GA-Z77X-UD5H
16gb Corsair Vengeance 1600mhz
256gb Corsair SSD

Even when I had the BLCK setting at AUTO, it would still fail at the 12 minute 30 second mark.

you probably needed a little more qpi/vtt than stock,auto usually uses around 103bclk unless you manually set it to 100mhz(sorry that was for the random freezing) for linx you could need a higher level llc or bit more dvid voltage for the cpu or bit more qpi/vtt,you would need to test ect

Here is Intel's voltage recommendations for IB cpu's

Intel’s recommended voltages and my recommended voltages

Edit - Wazza edited his post while I was posting this. I posted this as he was talking about qpi/vtt voltage compared to SB cpu's.

I bumped up the QPI/VTT to 1.08v, the VCC/VCORE to 1.3, and the PLL to 1.5 and the LinX still fails around 12 minutes and 24 seconds in.

Anybody else with Ivy Bridge & Z77x-UD5H run LinX test?

Hi guys,

I bought three new computer parts:

1) Gigabyte Z77X-UD5H motherboard
2) Intel i7-3770K cpu
3) G.Skill Sniper Low Voltage Series, 8GB PC3-12800 DDR3 kit (2 x 4GB) ram

I'm suffering from the same freezing problems:

-it freezes in the BIOS
-it freezes on the desktop
-the computer turns off when I do a MemTest, usually within an hour.

At first I thought that the RAM was the problem, so I took it back to the shop for testing. They did a MemTest for 5 hours and said that there was no problems. I also borrowed a single stick of RAM from a friend and still got the same freezing issues. So it's not the RAM.

Anyways, I just flashed the beta BIOS version F8a, loaded Optimal Defaults, and Saved & Rebooted. After doing that I was able to run MemTest for 5 hours without the computer turning off. Also, I have not experienced any freezes on the desktop and in the BIOS so far.

So guys, I think it's a BIOS issue. I'll post back if I experience any freezes today.

UPDATE: Just had a random freeze on the desktop. I'm bringing this board back.. too much of a headache!!!!!!!!!!!!

I returned my UD5H board and exchanged it for a Asus P8Z77-V. Problem solved! No more lockups!

Re: GZ-Z77X-UD5H Random freezing and shutdowns.

I'm looking to replace the UD5H with a Asus P8Z77-V pro or deluxe - can't make up my mind at the moment but good to hear the Asus boards are OK.

@boondock's and others... When using LinX or IBT to full stress the system you have to use all available memory

I'm still running it, but so far so good. ALso ran Prim95 for 8 1/2 hours last night next went above 74C. Using 100.1 BLCK, 43 multiplier
