What's the max FSB*multi I can do on a E2220 on stock volts

my RMA motherboard finally came in today and I can't seem to get it to do a FSB of 250, 256, or 266, those are 3 settings I tried but were unstable, I have 1333 ram in it but its well under the stock clocks as its a 800FSB CPU (266*4=1064)

it may be that 1333 ram can't handle low timings even at lower freq, I'm tired and haven't fooled with it much so tell me what you guys thing

after grinding on it for 5 hours this is what I got, thoughts?
