They write the chip runs fine on nForce 590 SLI based motherboards and that it overclocks really well:
The amazing 3.05 GHz overclock from last week was done on a retail available motherboard from one of their manufacturers.
The machine was running a quite usual memory setup with 2x1 GB of DDR2 memory. So the good news is that you don’t need to swap your motherboards, you just need abios update and your AM2 boards should be able to cope with Agena processors.
Even the overclocking was done on Nforce 590 SLI motherboard and not on Wahoo or Mako next generation chipsets. Agena FX is the first one, coming in Q3, and Agena will follow at later time.
