C-state OFF = Lower RAM/CPU performance!!!!

[Snake_Eyes]

Hmm this is strange yea.

I have i7 860 on a P7P55D Deluxe. and have C-state enabled and i get better reads and writes to in Everest.

But only if i set it to C6 state, if set to C3 or C1 then the writes are normal (lower)

3,8Ghz overclocked i7 860: All power savings are off because its overclocked.

Reads C-State Off 15781 MB/s
Reads C-State On (C6) 18252 MB/s
Test take little longer when C-State are on (maybe because that i dunno)

What is the best option to set then ?
Does it matter if i leave it at C6 state because better reads and writes ?
Or can i set it better off because i have a Vertex 2 SSD ?
The power savings are off, so i don't know if the C6 state do change the results of my SSD.

Any idea's what to do best for my situation ?

Edit:

Here a screen of a test of C-State and a SSD:


First screen is C-State On second screen is C-State Off
