z77x-ud5h bclk spiking

[thetanine]

Just recently I have been having issues with my setup and couldn't really diagnose it. It would lock up for a few seconds or the sound and video would spaz out and just the other day, hdd corruption.

Finally figured out that the bclk was spiking at random times. Still cannot find out why as I have changed nothing and its been fine for almost a year.

I found out it was the bclk when I looked at hwinfo64 and the maximum it hit for was 109!! It must only hit it for a few seconds and return to normal.

I have reflashed the bios, cleared cmos, used default bios settings, basically anything that could be the culprit. No luck. It still spikes every now and then and its usually hours into my pc running.

I use no OC software or anything like that, its a fresh windows install ( as my hdd got corrupted ).

Anyone have any ideas? I think the motherboard is dying as I don't think a CPU could cause this.

I am thinking if its the motherboard dying then I might have to get a z87 setup.

That's a strange one. I have two Z77 UD5H boards myself and I've never seen that happen. You should put in a support ticket with Gigabyte.

Guess nobody else has had this issue which kinda tells me it must be motherboard going out.

Re: z77x-ud5h bclk spiking

flash the last beta from this forum, then pull out battery and short clr_cmos for a while ... at least 10 min I'd say.
if that doesn't work, 100% defective board. I have the same issue and hope to finally get a nice Asus board after infinite Gigabyte RMAs and microstutter.

I gave up on trying to fix this UD5H. I got almost a year out of it but I am pretty sure its almost dead now.

Today the bclk even went down to 72 and as high as 104. I have tried almost every BIOS and have cleared the cmos so many times and the issue remains.

I don't want people to think this is normal or common for this board because I haven't heard anyone else having this issue.

Re: z77x-ud5h bclk spiking

I had unusual bus readings(drops to 84 or 78) when Intel VT-d was enabled in BIOS (F18 Z77X-UD3H , F19 betas didnt help much, got tired of settings amnesia), after disabling bclk shows 100.10-11
Still rarely (usually during skype calls) cursor stutters for 2-3 sec and then system just locks up, no event logs, etc (looks like bclk related stuff).
C3/C6 disabled, no OC, no Turbo.
Strange these Gigabyte boards are).
