X79 MEMORY OC GUIDE (4 Different IC) --- G.SkILL + ASUS Rampage IV Extreme

[Random Murderer]

So I tested with OCCT and it is OK with RipjawsZ (2133 9-11-10) at 2400 10-12-11
But I get errors with RipjawsX (2133 7-10-7) at 2400 10-12-10 (although it is OK with HyperPI 32M at 2400 9-11-9)

The settings

Vcore: 1.29v (4.5Ghz)
VCCSA: 1.05v
VTT: 1.15v
Vdimm: 1.65v
PLL: 1.80v

The ripjawsX do not like quad channel in h24 (stable OCCT, LinX, etc ...) it's just good for bench?

Whoa, that's a bit low for VCCSA at the parameters you're trying to run.
1.1-1.125v VCCSA and a slight bump on PLL(1.82ish) should help drastically.
Try that and report back.
