I am currently running a 64x2 5000 cpu on this mobo (n68-s) and thinking of upgrading. I looked at asrock's cpu list and did not see the 840 listed. The 840 is a 95 watt chip and I remember talk about it being an overclocked Athlon II X4 650. The 650 is listed. So with all this research I think it will work. But I must be certain, has anyone done it that will tell me it works.
Also if you think I'm on the wrong track with the 840 what would you opine
