I have just tested max bclk on my R3E and I m very pleased with it.

I hit 259 max bclk on air - with slow mode - PCI-E 115MHz - VVT 1,45V - IOH 1,27V

I think that I could go further, but QPI Link over 4100+MHz is so hard to get on this board. QPI multi in slow mode for 980X is much higher then on i7 920 and I hit 4100MHz QPi link on 259 bclk while on 920 it would be around 3000MHz

And here is 254 bclk 32m Spi run - air cooled - no system tweaks


and Everest - trial version of AIDA


maxxmem - not optimised



The 0096 Bios seems to be best for me in 3D and 2D.
