Gigabyte EX58-UD5/Extreme Discussion Thread

OK, so Im back at 3.6GHZ w 9gb RAM. Havent tried to push further yet, but this is what I have done to get there:

My situation appears to be that any time I try to overlock with my 3x2GB 1600 G.Skills in place, I cant touch my BIOS settings period without my rig going into a reboot loop that eventually resets itself back to defaults. BUT, if I just have my 3x1GB 1600 Corsair ram sticks in, I can tweak away till my heart's content, and THEN add the Gskill back in place, which then boots fine. When I do this, the only thing that BIOS appears to change are my RAM timings, which go really loose up to 10x10x10x26x2 when all 9 gigs are activated.

Here are my settings for 3.6GHZ w 9GB Ram:

QPI Link: Auto (6.48Ghz)
Uncore Freq: x17 (3060)
Isochronous: Enabled

CPU Clock Ratio: 20x (x180)
Intel Turbo Boost: Disabled
CPU Cores: All
CPU MT: Enabled
CPU (CIE): Enabled
C3/C6/C7 State Support: Enabled
CPU Thermal Monitor: Enabled
CPU EIST Function: Enabled
Virtualization: Disabled
Bi-Dir Prochot: Disabled

Performance Enhance: Standard
XMP: Disabled
Sys Mem Multiplier (Auto): 1440
Dram Timing (Audo)

CPU VCore: 1.25000V
QPI Voltage: 1.195V
IOH Core: 1.10V
Dram Voltage: 1.500V

So nothing exotic, and really conservative voltages obviously.

Will do some more experimentation later this week, but Im guessing that, again, if I dare touch BIOS with that Gskill in place i have to start from scratch with only 3gb in again to get started. Does that at all make sense? Stay tuned for further testing.

Many folks have had trouble ocing with 3x2GB, at least you now have a procedure that works.
Try not to use auto settings - you want to set these values - not leave them up to the bios to estimate for you what is best that way you KNOW what the values are.
Uncore looks nice and low for ocing - is this 2x memory plus one click up?
Do you get better oc results turning off eist, c1e, c3, ... many folks have found they can oc higher if they turn all this off - the downside is your idle temps are usually a bit higher particularly at much higher cpu volts.
After you get your oc stable with 3gb and add back in the other 6 can you then adjust back down your timings?
If you have xmp capable memory try runing just that xmp memory, turn on xmp and see what ET6 says your voltages are at - this gives you an idea of what mem and qpi volts the memory manufacturer wants you to run when at xmp speeds.
All your voltages are nice and low - should help you keep your cpu nice and cool!
Downside is increased oc at these voltages can be had only by a very few i7s. , certainly not mine.
