Okay, I have been trying to wrap my stupid brain around all of this and I guess I'm just really slow. Right now I have AI tweaker set to Auto in my P6T Dlx V2 bios. The only thing I've changed so far is setting the mem speed to 1600, as you know its actually 2000MHz GT corsair stuff, since Im running 6 sticks=12 gigs. I'm pretty sure, based on other posts that mines a decent CPU as its a Batch 3003B396 C2 from Costa Rico according to box. Running prime95 for several hrs on all threads highest any core got was at I think 64 for a sec but normally their sitting at around 27-32c. I just am inept at understanding what to do next.
I have read a ton of the posts here and its just confusing me more than anything. Now to up my cpu multi I guess I need to switch AI tweaker from Auto to manual to change it but from there I get lost. With my old boards the multi was a simple choice of multiplier but with this board I guess I have to do some basic calculations because the cpu setting is a ratio not a fixed number
What I would do to get a higher multiplier is set the CPU ratio number to something that equals (number x 2) -2 and thats the number I want to manually enter for CPU Ratio in my bios. for example with Auto my multi is 26 so if I wanted to enter it manually in the bios I would put 14 to have the same setting as I do on auto (14x2=28) -2 = 26. Do I have the gist of it? If I leave my bus and mem speed alone, to try and get my cpu to run faster, I'd enter something higher like say 15 which would then give me a cpu multiplier of 2 x15= 30 - 2 resulting in a multi of 28? Later, if I really want to push luck, can also up the bus speed from 1.33 to 1.44, which is XMP setting with my old memory.
I know I'm probably annoying with my questions but I want to do things right. I figure its best to ask those more knowledgable than to blindly screw things up. If I wasn't disabled and had a local social life I could bother people near me but as things stand I have to rely on your expetise here and your compassion towards a OC noob.
Sincerest Thanks for any help

Hey bratboy best to start your own thread - i moved your post to a new thread here Asus P6T Deluxe V2 + i7 980X 3003B39 + Dominator GT 2000 help

I learned one thing today, after spending the past few days overclocking my newly acquired Core i7 970, that to much CPU VTT also can cause BSOD 124's. Sigh.
And thanks for the great explanation. As far as I can tell, I currently am able to use less CPU VTT since I have put it on 18x uncore.
