Jusrt got the P5K Premium to replace the P5K Deluxe that I erazed the EEPROM on with Asus flash. I booted straight up on delivery BIOS 0102 with 445x9 on 1.55v and memory at 1110 on air. I couldn't do that on the deluxe with the same CPU and memory so first impressions are that the different capacitors appear to make a difference. I will play with it a bit more and see what it takes to run orthos stable. Just wish I had more faith in the temp readings
