PC will not resume from sleep after OC

liscoe · 13 May 2011 at 14:11

I have noticed that since overclocking my 2600K to 4.5Ghz I cannot resume from sleep. It worked fine before the overclock and the only other change I have made is increasing the RAM from 1033 to it's specified 1600MHz. The pc seems to switch back on ok (I am assuming as lights/fans etc start up) but the screen does not come back up and I have to reboot via power button.

My setup:
2600K @ 4.5GHz
8GB Patriot RAM 1600MHz
Asus P67 Pro (R3)
570 GTX
850W PSU

I have recently built a friend a pc (slightly lower spec'd 2500K, gtx 460) and noticed exactly the same problem with his. It just seems that the graphics card doesn't wake up with the rest of the pc. Has anyone else suffered this? Very annoying!

This!

It's a known issue when clocking the Asus p67 (p8p67) Motherboards - if you haven't done so already, the above advice 'should' solve the problem.

ive had that problem with loads of mobos.

normally ive found its because it need more volts for some reason.

Leave it on and disable sleep?

Thats what i did, after i read it was a problem with ASUS boards and could not see any fix (until now).

I cant tell if you are being sarcastic Sin_Chase, is disabling sleep ok or would i be best to use the fix from above.

I commonly disable sleep on my PCs as i like them to be on 24/7 and i have never had a problem nor a PC fail on me, saying this my other PC's don't have such largish OC's on them (i5 @ 4.4 - idle 40c) so would enabling sleep be better for the hardware?

You can disable sleep if you want - i, personally, don't use the feature.

As long as you can afford the electricity bills it isn't really an issue. Most of my PC's have died when starting up, so there's an arguement to be had that it's better leaving the PC on - initial boot up certainly stresses the PSU more for example... (I think Sin_Chase's post was a light-hearted way of ponting out that' it's not required.)

But 'if' your friend wants to make use of the feature he should try disabling 'internal pll overvoltage' in the BIOS first.

No sarcasm.

I don't use sleep as I don't really see the point. GPU will down-clock itself in 2D mode, my monitors are set to turn off after 15 minutes, SpeedStep downclocks my i7 to 1.6GHz with 1 volt and I never want my HDDs to spin down so disable that also. SSD has very little idle usage as does my mechanical 500GB anyway.

I just do not see the major benefit of sleep. I can cold boot my system in just as little time as resuming from sleep without all the extra hassle and proceed to load apps into a state it was when previously on in about 5 seconds.

Cannot download in sleep, recieve IM's, e-mails or otherwise so if you want to save power, just turn off?

It's certainly not any better or worse for hardware than leaving it out of sleep.

Thanks chaps! Disabling internal pll overvoltage in the bios seems to have fixed the problem...

I don't think that leaving my pc on 24/7 will do it much harm I just prefer to switch it off at the end of the day or sleep it if I'm away for a few hours (and don't want to reopen all my apps on my return). I can afford the electric bill it's more a slight feeling of guilt for burning a little more fossil fuel for no reason I suppose :-)

Not had a pc die on me when starting up or left on touch wood (apart from an unfortunate incident with a leaking water cooling system), so fingers crossed. Thanks again for the fix!
