So, C states I either enable or disable, I don't leave them on auto. On my Gigabyte board I did have some fair sized voltage swings, I have seen much less of that on my ASUS board.

C3/C6 are the ones most often suggested to disable if you are having trouble getting stability. I don't own an SSD, I have read something about C3/C6 and SSDs, but I glossed over it and don't recall the reading.

Your RAM either works at 1.5v or it doesn't. .025v isn't going to hurt anything.

Sorry, I'm not much help to you this round.
Thanks keto! Well, Your helping the way you can! That's whats important! And I appreciate it! ;)

Well, I will have to test more about those Cstates. Here's where i read (one from many others) about SSDs being affected when disabling Cstates : Official ASUS P8P67 Series Overclocking Guide and Information

This post was maid by a "supposed ASUS Technical Marketing Rep"
In addition continued testing with the PPL option enabled and D2 or retail parts have shown some benefits to CStates being disabled when approaching, at or exceeding a 50x multiplier. An important note to keep in mind is that disabling CStates can considerably affect HD performance ( especially SATA6G ) Please keep this in mind when going for the highest level overclocks.
SATA6G being the ports SSDs and SATA3 HDDs uses.

But with those 3 CStates set to Enable, IDLE voltage was really swinging bad from 0.760v to 1.220v. Can't recall if I even tried LOADing Prime95 after seeing that much of a swing when IDLE. Anyway, like i said, I will have to investigate a bit more on that heh

As for DRAM voltage, well, I ran Memtest86+ (the one that you run before windows boots) for 2 hours (2 Pass) with my RAM beeing set @ 1600Mhz with manual voltage set 1.500v and timing manually set to 9-9-9-24 2T and all went well. No errors. So, I suppose I should set it back to 1.500v for now until I start Ocing the RAM.

Now, something else... Check this out :

I heard that AID64 EX Stability test was a more appropriate\realistic way to Stress test the CPU since the LOAD it applies to the CPU is not the same at what Prime95 would. The temps you get from stressing with Prim95, you will never get them either when playing an intense game such as Crysis 2 or even when folding@home... So I suppose this statement is true. Either it beeing true or not, I still prefer to stress my CPU for stability using Prime95 to make sure IT IS 100% STABLE. Either way, I decided to give it a shot. I presume the LOAD it applys to the CPU would be relatively the same (actually probably more) as the LOAD Crysis 2 would apply to my CPU. Well, Guess what, here's the Vcore i get when stressing with AID64 EX ...

Seeing this, I assume that when I'd be gaming, my Vcore core would be at 1.384-1.392v ... And that isn't really what I am looking for isn't it? I stressed the CPU with AID64 EX and got that Vcore. I then stopped the Stress and started Prime95 ... And my Vcore was at 1.368v ... Like if, depending on the intensity of the stress the CPU would get, the Vcore would go down as the intensity gets higher.

Now this is confusing...! Any ideas?
