Overclock lost on wake from Hibernation

[johnjk]

Hey all,

Looking for some help her. I have an ASUS A8R-MVP motherboard with a x64 4000+ I can get some great overclocks and am stable at 2.9gHz. One problem, I have noticed that when the computer resumes from hibernation the overclock is lost. If I manual overclock it, it either drops to normal or if the HTT is above 250, it reboots at overclock/2. If i reboot the computer once windows starts the overclock is back in place.

Is there a bios setting I need to change?

Is this normal (Iam doubting it)?

What is the power savings from going from S3 (suspend) to S4 (hibernate)?

I've always used hibernation for the supposed power saving benefits. I just tried suspend and it turns out that that doesn't work. Suspend will turn off the computer with the power light blinking like it should, but when you turn it on, it takes about 20 sec to think then resets and fully loads windows as if nothing where in the ram. This even occurs with no overclock.

This has the added benefit of reseting the computer and thus keeping (or rather not lossing) the overclock that occurs with hibernate. However it takes longer to boot.

Any thoughts???

Is this Bios, Motherboard, or Windows XP related???

Please.. do not make more than one thread :roll:

It's most likely a problem with your BIOS. Check with your motherboard manufacturer for a BIOS update. It's a very common problem to lose overclocks after hibernations, suspends, or other power-saving modes. I just looked on the ASUS website, click here, and found that the motherboard will display the improper frequency when resuming from the S3 power state. Make sure you are comfortable with upgrading your motherboard's firmware and post your results.

Bios is completely up to date. Please refer to the below link with more information on the problem and others solution ideas.

Oddly enough, the issue was due to the new bios that I updated to 3 months ago. After going through 10 index pages and 20 posts on ASUS's website I stubled upon a strikingly similar story. The solution is to downgrade the bios from 05.03 to 04.02. Now the board is rock solid stable.

I can now achieve HTT of 325. Booted perfectly and primed for an hour no prob.

I also have a max HT Link of 1079. Booted perfectly and primed for an hour no prob.

Seems like my opty upgrade is back on. Now I just need to decide between 165 and 175. Thanks all for your time, effort, and help.

And if you have any ideas post your thoughts on the Opty purchase. I will be creating a thread shortly to discuss it.
