MrBunglex,cpu on water and videocard only.Have several 80mm fans over ram,nb and voltage reg area. My notes say vfsb is set at 1.4v.Idcc says 1.425v in ss above.Note,i just tossed alot of volts at it.Should be able to tweak lower.
Manel,flashing from 1251 to 1507 if i remember did not save anything.May want to wait.Heres a good read on gtl's:
