Tonight, I'll play around with the ram that I have and put 8 GB of the Gskill with my E8600 and 8 GB of the HyperX with the Q9550. Both are using this MB.

I'll let you know what I come up with.

When using all 4 memory slots, I have to increase the NB voltage, right?
Vnb probably around 1.4-1.5v, Vdimm increase by 0.2 from 1.9V ( for my case even at 2.2Vdimm still unable to boot )
Can test from there and lower if it is stable. Doubt it can do, tested mine can do only at 1600mhz 9-9-9-25 at 2.0Vdimm with 4 sticks..no higher
