Except for the Vdimm mod plus the 4 mods + extra caps that help Vcore, the board has no other modifications. The CPU is good for high FSB (540+ on DFI 965, 600++ on Asus P5K with VPLL mod), and other mods tried so far (VGTL+, VSPP) did not help. The only thing I might need to investigate is the VPLL mod, if it's possible it may bring a new light to 680i benching.
