oc question

I just recently purchased a NF7-S mobo off of another member. The previous owner suggested that it was 220 FSB capable and that put it in my "insane oc'able" category. I had a previous NF7-S and it crapped out after 211FSB.

So, I get it all in my system, set the bios to something "low" like 200FSBx12multi and all is well. I am confortably back to my safe oc of 2400.

But, I want to go for that high FSB. So I set it to 1.85v, 11x and 217fsb and I get prime95 dropping out after just a few seconds. Drop it down to 211, my other boards previous stable point and I stll get errors. I raise it back up to 217 and run memtest with tight (2) and loose (2.5) timings on the ram and no errors. So what gives? i thought I saw on another board (amdmb?) that 10 or 10.5 multi is where the high FSB oc's are at. Is this true?

Can anyone provide any comments on this? What are you setting things at in your bios?

I have tried quite a few things and have been mining for info here for some time but I feel that I am missing something. Temps are high 30C's idle, CPU Interface is Enabled, 6:6 cpu/ram ratio, what else?!?

The system I have is listed in my sig below.

Thanks for any help/comments you can offer!
 
vdd was at 1.7 (bios max). I even "briefly" jumped my vcore up to 1.9 (1.86v actual) and still had failure.

So. Is that the secret? Is everyone doing the vdd pencil mod to up the chipset voltage? Or should I just RMA the board I do have that is rma'able and hope for the best on the return?
