Hi all. Just wondering whether anybody can help me out with my problem..



I'm currently running an i7 940 on a gigabyte ex58-ud4p.

When i increase the base clock to anything higher than 155, the system won't be able to resume from SLEEP.



At bclk 155 and below: No issues.



At bclk 156 and above: Unable to resume from sleep. No BSODs, no errors in prime95 or such, nothing. EVERYTHING else is alright, just unable to resume from sleep. Fans, lights and leds all come on, but screen stays black. Keyboard and mouse stay dead too.



I've tried lowering the cpu multi, lowering the ram multi and increasing/lowering vcore, qpi, dram voltages. The only thing that works is setting the bclk to 155 or lower. I doubt it's an OS or software issue as i've tested on a seperate hdd running vista and another running xp, all with the same results.



Anybody got any ideas?



Here are my pc specs:

intel i7 940
gigabyte ex58-ud4p (f8 bios)
ocz ddr3 1600mhz
gigabyte gtx295
thermaltake toughpower 850w
win7 ultimate


Thanks in advance!

What's the point of sleep mode on a desktop anyway? It's understandable on a laptop to save the battery, but why not just let it idle or shut it down? Or better yet, fold with it.

I normally have quite a few open and unfinished projects. Sleep allows me to continue my work faster, without having to reopen all my stuff :p

A lot of motherboards have issues with sleep on overclocked systems. It didn't work on my P6T nor does it work on my eVGA. Well...sleep worked fine just like yours does, waking up was a different story.

I just got a P55-UD3R and it is the first board that Sleep works 100% even when OCed heavily :D

Try the "Smart 6" utility from Gigabyte.

Just go to "Smart QuickBoot" button and enable "OS Quickboot" then when you shut down it just goes to sleep and can be woken up with a touch of the keyboard or mouse (or power button)

This may sound dumb but have you tried hitting spacebar?

My system does the same thing and the only key that brings it back is spacebar. I am not sure if the issues are related but its worth a try.

fwiw my i7 on my UD5 behaves the same way. It will enter sleep just fine, and you click the mouse, hit space or whatever to bring it out, all the fans and everything light up, but it will hang after that. I just gave up trying to figure it out, i fall asleep to the drone of my 5870 @ 65% fan speed LOL!
