Asus P5K3 Deluxe BIOS
As you would expect, the BIOS on the P5K3 Deluxe is very similar to that of the P5K Deluxe, though this motherboard stretches the overclocking bounds a little bit further.
The BIOS offers DDR3 memory speeds of 800 MHz, 889 MHz and 1066 MHz.
The latencies are going to be higher and in fact our tests were done at 7-7-7-20 with a CAS latency of 7.
I also noted that there were significantly FEWER options for memory tweaks on the P5K3 Deluxe possibly due to the immaturity of the platform.
