Jumping voltage in cpu-z

Recently got a new board (ECS KA1 MVP (1.0) Socket 939 ATI Radeon XPRESS 200 CrossFire) and started to OC. However in CPU-Z the voltage keeps jumping. I set it to 1.4v in bios, but in CPU-Z it jumps around ranging from 1.37-1.42, is it a faulty board?

thanks!
 
No. That is a normal occurence. The voltage does fluctuate a little bit. CPU-Z display your CPU information in real time so that is why you see it 'jumping around'.

If thats stock voltage, i.e you haven't tried to up the voltage. Then that is quite bad. My voltage on the s939 boards i had fluctuated as bad as yours only when i had upped the voltage, when i ran stock voltage there was very little if any voltage fluctuation.

Maybe someone with that board can indicate whether it is normal trait at stock voltage.

Rich, the more expensive the motherboard, the less the voltage will fluctuate. And ECS obviously isn't an expensive motherboard.😉
 
I haven't got home yet to look it more. I got this board after a fair amount of research. Even anand wrote up a pretty decent review about it. I just hope its not a faulty board.
 
Well, just because it got a good review (for how far it could overclock, if I remember correctly) doesn't mean it isn't going to have fluctuating vcore, like most cheaper motherboards have. It just means that you may have to raise your vcore higher, if you decide to overclock. Not that big of a deal, really.
 
That is a bit of a fluctuation (still less than 5% though) but if your CPU is stable, then it's stable. CPU-Z shows mine alternating between 1.424v & 1.440v.
