When it came down to overclocking this board, I felt kind of cheated. Since I just reviewed the Jetway MA3785GP-LF just a couple of weeks ago, I elected to go straight to the settings that got me 4012MHz with that board. Because the Asrock has much more BIOS options when it comes to DIMM and voltage controls, I felt this would be no issue. I was right. It booted right at 236MHz on the HT. Since this was no problem, we kept the 1.5v on the NB and was able to get to 242MHz on the HT for 4114MHz a small nice increase over what the Jetway board did.
