i just got the UD5 this weekend. i am currently using a 1090T with a Prolimatech Megahalems. my previous board was an MSI 790FX-GD70, which was a rock solid board. the 1090T ran 4.141 Ghz on 1.44V, 2828 Mghz cpu/nb on 1.34V.
with the UD5 i am at 4.0 with the BIOS set to 1.45V, and this is where the disappointment begins. number one, why the huge .025V increments for v-core and cpu/nb voltage?
i am currently using Aida64 for monitoring, though HWmonitor reads the same...so, 1.45 vcore in BIOS, Aida64 reads 1.48V idle, and drops to 1.42V under stress testing. i have read enough about this issue with this board, unless a solution is forthcoming, there will be an rma in my future. my first Gigabyte board and i am unbelievably disappointed.
