Can you go to the boards manufacturer and DL the boards manual and read it, see if it says you can raise the BCLK.
Not too many seem to buy that board, I would think there is a reason for that.
Check your local Craigslist for motherboards.
I picked up an EVGA FTW3 for 60$ and I have seen a couple Sabertooths sell for 100-125$.
I missed an EVGA SR-2 with 2 hexcores and a 1200W PSU and 24gb memory and case for 600$ Missed it by just a few hours too.
I found on e-bay an Asus Rampage3 for 100$ just listed as Rampage3, So don't just look for x58 or lga 1366 boards.
