Hi guys,

Got the 890GX Exterem3 + X2 555 since yesterday and I was able to unlock the two extra cores so it became a X4 B55. I've had it Prime95 stable for 3 hours so I decided to reboot and install some new drivers. After this the CPU returned to a X2 555 again and so far I've not been able to unlock the two extra cores again. I've tried it with every bios available on the Asrock website, but no prevail. Anyone knows what I might be doing wrong? Since I had it prime stable for 3 hours the two cores must be working good right?

Regards, Quintus
