Whenever I set the aperture to 128MB, it will force a CMOS reset upon me. It simply will not POST or boot at 128MB. This was with the stock BIOS.

I updated the BIOS a while ago, but last night I tried 128MB and it worked fine. Then, this morning, it wouldn't POST. I reset and put everything back to where it was with exception of the aperture and it works fine now. I thought the new BIOS had fixed this last night, but it is quite clear that is not the case.

My ECS K7S5A(KT266) did 128MB fine with the same video card.

Anyone have any ideas as to why this is happening? I know the performance difference is minimal at best, but I'd like to know why I am having these problems anyway.

Thanks.
