I have the same problem with the Abit AS8.

the 1:1 ratio is great.
the 4:5 ratio does nothing (I run a 533 FSB Prescott, so those are my only rations available) I can get all the way to 250 at cas 2-2-2-5 just fun with the 4-5 ratio, but it does absolutly nothing.

I even thought sisoft sandra might now be able to detect the odd ratio or somthing, so I ran lobby high and lobby low, at 1:1 then 4:5 and didn't see a single improvement.

I think the 4:5 feature of my AS8 is a phantom feature, it's there, but it does nothing.

i hope for a new bios to solve this "bandwich" problem..

Yeah, running DDR2-533 async with 800FSB Prescott and 1:1 with better timings pretty much zero gain.
