I'm wondering if whoever sold you the 7810 installed the 2 cpus before selling without testing it aside powering it on. I'm a paranoid so ... I'm thinking about 2 options :
1) by real bad luck, one of the cpus has issues
2) bad installation of one of the cpus in a socket leading to some socket pins to be bent
Can you still return it ?
Are you able to test it with just one cpu installed ?
I can not check it now, but if I am not mistaken, the "multicore support" option is applied to all the CPUs equally.
If so, I see 3 options possible.
1)The heat-sink was installed without properly applying thermal grease/plaster, or the protecting tape was not removed from the fresh thermal plaster. So the system boots on its heat-spreading power limit.
2)Damaged socket pins, insufficient testing during RMA
Thanks for your replies, as I saw it coming - no silver bullet so far! So I'm facing a discussion with the dealer! And it's not going to be easy - the onboard diagnostics is of little help as it checks only memory access and it passes without errors even with all cores enabled, during the test temp was below 68 dgr C, so thermal paste should be OK! Anyway thanks again for your efforts!

3)Damaged CPU, which is less probable, actually.
O.K., and the RMA board may be simply bad.
