2.80 Mhz CPU at 2.32

[rods11]

My brandnew shuttle XPC ST62K equipped with a 2800mhz 1gb L2 cache, 800 mhz FSB has problems to accept it as a 14 x 200 mhz = 2.8GHz speed cpu.
If the bios is set to auto it will acctept it as such the first time it boots, but the second time it is reset to 166 x 14 = 2,32 GHz.
If it is manually set to FSB 200 then it will see it as 14 x200 = 2.80, but again, only at 1st boot.
The cpu is correctly described as a 2,8 mhz (also in Sisoft Sandra) but sometimes running @2.32 other occasions @ 2,80 GHz.

The bios is dated feb 27th and there has been no revision since.

Shuttle blames Intel, Intel blames Shuttle as usual....

Has anyone experienced similar trouble or knows a solution?

Try and get a bios update for it. That might help.

try to read the question zap hod ... quote: The bios is dated feb 27th and there has been no revision since.

Oh sh*t really sorry.... It was early in the evening to so I can't even blame being tired!!

Thats really annoying the whole Shuttle blame intel - Intel blame shuttle, it's typical.

It's really strange problem. Have you tried Flashing the cmos, reseting all bios settings and starting again. Apart from that I can't think of much more...sorry!

Are you sure you bought an Intel Pentium 4 2.8a/b/c?

Clarify what you mean by:

It won't accept it at 14 x 200

the cpu specs are confirmed by Intel

Clarify what you mean by:

after resetting the bios it runs at 2.80 at 1st boot

after a 2d boot it goes back to 2,32

unusual....so it recognises it first time out...and then loses the plot

I don't know Shuttles, but is there a jumper on the mobo to select default FSB?

Tried replacing the CMOS battery?

[r1zeek]

Very unusual.

If you can change the multiplier then you could always use an FSB of 133 and multi of 21 (thats what my P4 uses)

[rods11]

No, only in the bios

[Shogun]

It sounds like the cmos battery is dodgy since the settings are changing when you switch off. Try changing a setting you wouldn't normally change and then switch off. See if this setting changes back to what it was.

The problem was solved.
