Asus Crosshair IV 0801 Bios

Dave you shouldn't have much issues until after 350 although depending on ram divider your using it could be straining your ram.

I am busting my hump to get the manufactuers to get 1/1 ram ratios working on ddr III boards....that should help out most average guys as 400HT with 1/1 ram divider = 1600 ram

I have already confirmed/debunked the myth that these chips aren't fond of HT and have been booting/benching at 420 HT.

Quite right on the ability to run 350Mhz FSB. Up to that point it is very easy utilizing the right ram divider.

On the FSB/ram ratio's, wouldn't 1-1 be almost impossible? You would need an 800Mhz HT and 1600Mhz ram(800Mhz CPUz) to be at 1-1. 400HT and 1600Mhz ram would be 1-2 ratio, which would be about the best you could attain on this architecture.

If AMD could have only refined the NB even further would have been a major performance advance on this architecture. Having the cache running at 1-1 at CPU speed in itself would take us several steps up, with the memory at 1-2.

I too am perplexed at the Asus boards inability to scale HT/FSB above 350-360Mhz. I figured it had to be the board and/or bios. When I tested for DFI back in the NF4 era alot of the NF4 boards had trouble pushing high HT. Abit, MSI, ECS...I had a bunch of them and none would do much better than mid 350's. The early DFI NF4 would not boot up at 400Mhz HT or higher, but we could push it up booting at a lessor HT and then using SetFSB to take it where we wanted it.

Subsequent boards had registers in the bios adjusted based on our feedback data and could boot at 500Mhz HT and higher.

Are you working on the Asus or Gigabyte Brian, or both? Can you boot at 400+ or are you setting it after boot into Windows?? Thanks in advance my friend
