Ok...i know much about overclocking but it seems that i want some more info

My question is what are the best OC settings?(If you are a evga 750i sli ftw owner...you can help VERY much)

Now...this may confuse you...but not by processor overclocking(not the voltages ether)...but like,for example,the unlinked or linked settings...and the multiplyer

to make it simple

whats better?having the multiplyer by 8.5 or 8?and what is better,Unlinked or Linked?(You know,that FSB setting)btw my memory is Corsair XMS2 800Mhz 4GB DDR2 RAM...so its high quality(see my rig below for more info)

or,of what i heard,is it better to overclock by the FSB(meaning put the multiplyer to the lowest,for me,its 6 and increase the FSB...)WHICH is a bad idea for this mobo because the 750i cant usually go over 450,or even sometimes 400...but mine can(bout around 400-450?,i could go 4.0ghz but like i said...it is HARD for this motherboard...yes i will get a new board(of a different company) but that will be later later...)

or the same method but insted keep the 8.5 Multiplyer...but the Mhz's wont be even(Ex. W/ 8x 2.500 3.000 3.500 etc. W/8.5x 2.584 3.156 3.572 etc.)

Thanks

and any confusion or infomation you have/need just tell me

FSB x Multiplier = CPU speed
FSB x Divider = Memory speed

So, with linked memory, when you increase the FSB you speed up both the CPU and the memory.

Any combination of FSB and multiplier that gets you to where you want to go is fine.
A CPU at 4.0 ghz doesn't know whether it got there with a 400FSB and 10 multi, or with a 472 FSB and an 8.5 multi. (you may see some slight performance differences at the same CPU speed with a faster FSB/lower multi, but you'd have to benchmark to see them.)

As for overclocking, when you change the multi by 1 you change the CPU speed by whatever your FSB is ( ie. 400 x 7 = 2.8 ghz, but 400 x 8 = 3.2 ghz. a 400 mhz change), but if you change the FSB you change CPU speed by whatever your Multi is (ie 400 x 8 = 3.2 ghz, 401 x 8 = 3.208 ghz, an 8 mhz change). Changing the FSB gives much finer adjustments.

I had this board and the same mem

top out the multi and link and sync the fsb to ram ratio

easy oc

That's quick and dirty overclocking.

When the OC hits a max you don't know if the RAM is failed or if the CPU failed.
Ninty-nine times out of a hundred one or the other will go faster.

But then, it IS an overclock.
