a8n-sli OC question, fsb limit?

Today, I tried a controlled OC on my memory. I upped the HTT to 300 (3x multiplier), and lower the CPU multipler to 6x, giving an effective 1800mhz cpu speed, stock for my athlon64 3000+. Then I put the memory divider to DDR266, therefore roughly making the memory running at 0.61*300 =183mhz, which is way below PC3200, stock speed for my hyperx valueram.

and #@#!?, no go at posting.

The machine is fine w/ HTT 270 (3x multiplier) and cpu 9x, and DDR266 (which is about 173mhz for memory).

This makes me wonder if a8n-sli has a PHYSICAL limit on FSB... The bios (1004) gives me options for higher fsbs. Bummmerrrrrrr.... any ideas about this bottleneck? What can I do to push my memory to about 200mhz, while giving a decedent CPU oc?

All boards reach a point at which the FSB can not be raised further, because they are not made to run at those speeds. Yours has probably reached that point.
