It's the rampage 1. For so far i know, that's what is they say on the box.
Also i can't see now what for specefic cpu i've because i can not start my pc. I don't have aonitor inplug at this moment.
The only thing i know that the cpu is bought at the seem moment as the motherboard.
And that it is a intel with 4 cores and 2,88 gh.
I can not change the ddr2 memory because the motherboard can only use ddr2.
I hope that this is more information.
