(tsc) clock too slow on Core-i7/ASRock X58

I have a problem with the system clock being off roughly 10 minutes a 2
hours on a Xeon W3250 (like Core-i7 920) using the 2.6.34 Linux and tsc
clocksource. Switching to hpet seems to improve the situation
momentarily, however, are there any other thoughts on this matter?

What I find odd is that the processor speed in dmesg (after TSC
calibration message) is 2.8 GHz, whereas BIOS says @2.67GHz, might that
be related?
