Shuttle Problem

[Platinum]

Wierd one this and I cant figure it out, got a Shuttle SB81p which keeps throttling, Its got a 560j processor in it, bios reads 60 degrees under load and speedfan reads the same when priming yet its throttling.
Any ideas, apparently the user has tryed a bios update for it, ive got it here to have a look at but im a little stumped , user says the CPU is faulty but ive always thought CPU's ether worked or didnt work?
Any help would be appreciated.

I'm assuming you mean throttling down in speed. I don't have a SB81P or an Intel rig but you might wanna check the Power Options and see what it's set to.

Unfortunately I have to go to work, but I'll back to you on this one.

Yea it throttles back to 2.8GHz

What about on full load?

It throttles back...

I think Tino (nice to see you buddy!) means... under load does it stay at 2.8GHz or does it fluctuate?

Well, checking [URL]http://global.shuttle.com/Support/SupportList.asp?Item=SB81P&ver=SB81P%20(FB81V1.x[URL] shows that it should be supported so the only thing I can think of is that SpeedStep or EIST is enabled. I don't see any point in enabling SpeedStep as it's really crap. Reduces performance and hardly improves on y'leccy bill.

Enough of my rant. Like I said, check the Power options in the Power Control Panel and if it's not on Always On, change it too it and reboot.

If that doesn't do anything then, try taking the CPU out, give the rig a clean and then bung it back in and see if it boots at the correct speed.

I'll keep thinking but I'm kinda drunk!

Stays mainly at 2.8 but if its left to idle for a while it sometimes goes up to 3.6
