Gigabyte EX58-UD5/Extreme Discussion Thread

[scyzer]

Anyone else please advise as well if you have Qflash issues after using a Beta dated after 3/11 so that I may pass it along

I just flashed my UD5 to F6e and yes I have the same problem (I've also loaded optimized defaults, saved, rebooted).

Will try bootable USB later on.

Mind you, I can't seem to get over a bclk of 180 stable.

I can do 180 fine at:

20x Multi
Vcore 1.3000
QPP/VTT 1.3000
Turbo/HT/All Power Saving Functions OFF
VDIMM 1.64
PLL 1.80
Memory Multi 8x, Uncore 16x

I've tried upping all volts and still cant get 190 stable!

Mind you, I've only used F5 and F6e BIOS revs.

Any ideas? Back down CPU Multi? Increase Uncore Multi? Change to another BIOS rev. (if so can you recommend a few)?

EDIT: A few things I forgot to mention.

Just tried a bootable USB, got F5 BIOS working again.

I cant get 3.8 or 4.0 stable at all, a few minutes of priming and BSOD. I've tried these settings:

19x Multi & 200 Bclk, 20x Multi * 190 Bclk
Vcore 1.4000
QPP/VTT 1.3600
VDIMM 1.66
PLL 1.88
Uncore Multi 18x

Memory is a G.SKill PI kit rated at 8-8-8-21 @ 1.6-1.65V

Any suggestions?

EDIT 2: Few more details which might be of use.

Load Line Calibration Enabled

185 Blck * 20x Multi seems to be stable so far (45min of Prime95)
