At BCLK212 it will run about 8-10 passes, and then 1 core drops out. At > BCLK213, the core drops out after 1-2 passes. Raising the VVT or loosing the RAM-timings didn't help . Even tho this setup has passed several hours Prime smaFFT at 4.1GHZ(216x19) 1.168v, but BCLK212 seams to be the BCLK-wall for RAM/IMC-stability at x19 multi on my setup.

I have been experimenting with QPI:Uncore 1:1 at x18 lately, and it was good to see it passing Hyperpi 32M.

@4GHZ (211x19) 1.15v , Hyperpi 32M:
I cant even get HyperPI with Bclk 191mhz to run anymore, even though it used to!
