Does overclocking generally cause reboot looping when resuming from S3 suspend?

This only happens to me if my CPU is running overclocked, NB and RAM seem to not cause the problem.

Here's my discussion so far with Gigabyte tech support:

You might go into BIOS and set the S3 to the 'other choice'...ie. S1.
Then reboot into OS.Shutdown once again and then boot back into BIOS and set the S1 to S3. Boot into OS. Set the Sleep, tried it again.

If the problem remains please test with other power which is included +5Sb.
Use PS2 mouse and keyboard to see if problem remains.Unplug other extension USB or PCI card at this moment.

if you still have any further question or suggestion about our products/service, please do not hesitate to contact with us. We will try our best to help you resolve the problem ASAP.

My BIOS settings with MCH & CPU OC: (DDR2 1066MHz @ 900MHz) S1 works, S3 doesn't work.

What is meant by "test with other power which is included +5Sb"?

I do not own any PS/2 mouse or keyboard.

I have 6 USb devices connected: Logitech G15 keyboard, Logitech G9 mouse, Logitech LX310 wireless desktop receiver, Logitech G25 steering wheel system, bluetooth dongle & 4 port powered USB hub.

I have not tried removing any of these devices at this stage as the problem seems to be caused by overclocking, probably the CPU or RAM.

The 5V standby power system i n the supply needs time to stabilize, and let some caps charge. +5SB is also used for the power enable circuit. The AC gets turned on, and +5SB comes up. This immediately activates the rest of the power supply, However, since +5SB's caps aren't charged, the huge load from the hard drives and motherboard starting up drain things, and it can't keep the voltage high enough for the PE circuit to remain on. Most supplies aren't made like this, but a few do have this problem.

If the issue is different from original, make sure you issue a new form by pressing "Ask more question" in order to get proper assistance and it may be response faster as well.

Can anyone shine some more light on the subject and perhaps recommend a fix to try?

My PC runs all day, S3 would save a lot of power.

How much power does S1 suspend use with just the fans running? Is it worth it?

Okay, I don't have particular experience with this problem have had something similar occur and since no one else has answered you I will weigh in with a few suggestions as to how you might further trouble shoot your issue... it will be time cosuming though.

You can try first off to disable any thing in bios such as run down features ( those that throttle back cpu when not in use ) to see if that helps, depending on results you can lower your HT/Link a bit to see if that helps, another thing and this is going to sound a bit strange to you but lower your ram speed a notch and see if it still does it.....

Odd little problems like what you are seeing 9 times out of 10 can be traced back to a voltage issue, for example when you come out of s3 and everything tries to power on at once your voltages some where are not stable and so the board reboots to protect itself... I hope what i am saying is making sense what you will need to do is some how change things in an orderly and logged fassion so that you can narrow down the part or subsystem that is causing this error. Get it?

Good luck with it and don't forget to check your system/error logs to see if you can glean anything from them too.
