**Official Gigabyte Z77X-UD5H Discussion Thread**

You testing with the rest of the the system at stock speeds? If your overclocked it might just be one stick can handle higher speeds than the other.

Yep all stock, reset everything when I updated the BIOS to F14. Going to run Memtest but im 99% sure there is a fault with one of them.
 
yeah looks like a fault then if one is working good and the other isnt, are you using XMP to set the memory up in the bios or did you set your timings and voltage manually?
 
I dont know what XMP is...:o But all the RAM stuff was set to Auto in the BIOS, I know very little about RAM so I generally leave it well alone. The timings matched the advertised timings for the RAM so im guessing it was all set up correctly?
 
XMP is just extreme memory profile, it just sets your ram up for ya automatically, but if it isnt showing up on the top of your Advanced mem settings page in the bios your ram doesnt support it, doesnt matter though its not hard to set up the timing your self later. If the mem was set to auto the timings were proberbly a bit loose, which means theyre less likely to crash, so i guess ya have a dodgey stick of ram, any other pcs ya can try the ram stick in just to make sure before you send it back?

No other computers to test it in unfortunately, according to the product page it is XMP 1.3 compatable, maybe im missing something?

Edit - Found XMP and it was disabled, ive set it to Profile 1 and will see if that makes any difference.

Hmm it seems to be working ok now, no BSOD on boot and it isnt instantly failing Prime 95, I'll leave it to run for a few hours to make sure. Looks like I have an apology to make in the Customer Service section though! Thanks for the help BluD :)

Speaking of BIOS's I noticed that the last 2 beta BIOS's don't seem to apply clocks from the BIOS unless you clear the CMOS each time. It was doing my head in yesterday and I was using ET6 but you can't lower the clocks with it so just reset my CMOS and stuck to a clock that I know works without effort.

all beta's are fine,some have niggles and some dont always fix your issue,you just flash to the one that works best for you

ive never had any problems with betas,they wont kill your board
