A7N8X Dlx rev 1.04, Memory

I have a A7N8X dlx rev 1.04 and i have the newest bios, but when i goto run My processer at 133 and my menory at 100, this is just to test the memory Frequency option but every time i try and use it unless i run the process and memory syncerous it dosnt work, it reboots and goes into limp mode, is there a setting i need to change for this to work? I would like this to work so when i get my 1700 DL3TC i can run it at 180+ and only have my cheep memory at 130 -140 untill i upgrade the memory.
Thanks

hmm so you want to run the mem at 100/200? set the mem freq to 75%

this mobo has issues with running fsb/mem Async, i've seen dozens of cases but all of them had ppl trying to run their mem at 200/400 and their fsb at less than 200/400....
