wake from standby obliterates overclock

MY FSB (set in bios to 295) drops to 200 when I wake from standby according to cpu-z 1.30?!

EPOX 9NPA+Ultra 10/18/05 bios, AMD4800 x2, Ballistix 1T-3-3-3-7, XP Pro all the updates

FSB 295, memory1t 3-3-3-7 divider 5/6 , multi 9x -> 2655 mHZ CPU, 245 mHZ memory

On boot, cpuz correctly reports the FSB and multi
sleep and then wake-> FSB goes to 200, multi goes to 10

Installing x2 driver does not change this behavior. Cool n quiet is disabled.

I also found something interesting-depending on which utility you use to measure FSB, you get different answers.
CPU-z 1.30 and ClockGen for nVidia nForce4 Version 1.03 will report an FSB of 200 upon wake from standby. Not surprising since they are both made by the same coders.
But so does crystal cpuID.

However, other applications like Central Brain Identifier 7.70 , GCPUID 2.0 RC, WCPUID and even the properties of 'My Computer' report the cpu speed and fsb set in bios.

ALL applications correctly report the fsb upon RESTART or wake from hibernation. It is just that on wake from standby that the numbers change.

This change is real and reflected in significant changes in benchmarks.

They are dealing with the same issue over at aoaforums.com under the epox motherboard forum. I hope it is not your thread.

Well I just checked and it is your thread, if it is any concelation I found those forums absolutely useless when it comes to help. They seem more interested in talking about the Epox tech getting more memory. I am sure that is why they created that forum. Now that I am done ranting.

I may have read somewhere that someone else was having this problem, only when they used suspend to S3 setting. S1 was fine. I think S3 suspends to ram and S1 suspends to hdd. Mind you I could be completely wrong on this. One other point to think about, is if it still actually overclocked after suspend and the readings are wrong. If the performance is still there do you really care what it says in a couple of programs. Hope this helps.
