Hey guys!

I've been a proud S2E owner for a while now and an avid reader of these forums also.
Now, I'm posting here today, cause I need help to solve an issue that's been driving me nuts and that I can't seem to get pass thru.
My setup is an S2E obviously, a C2D E8600 E0, 4 gigs of Dominator XMS31600C7DHX. On top of that, 2 BFG GTX 285 OCX SLI, Creative XFI Fatal1ty PRO and I recently removed for testing purposes a third card, an EVGA 8800 GTX KO ACS3 that was processing physx.
My setup is watercooled with swiftech apex ultra kit, cooling the NB and the CPU with a Swiftech GTZ WB.
Ok, I had my setup 100% stable with this settings:

Lync & Sync'ed with 1700 Mhz
RAM 7 7 7 20 2T at 1.9V
CPU: 1.25 V on BIOS LLC ENABLED
NB: 1.3 V BIOS
SB: AUTO
PLL: AUTO
VTT: 1.2 V

working like a charm!
So I went further

4.5 Ghz
FSB 1800 Mhz Unlinked
RAM at 1680 Mhz
7 7 7 20 1T at 1.9V
CPU: 1.375 V on BIOS LLC ENABLED
NB: 1.3 V BIOS
SB: AUTO
PLL: AUTO
VTT: 1.2 V

I think I'm really close to get it 100% stable, right now got Prime running in the background with small FFT's, an hour gone by an lookin' good!
Had some problems here in the past, cause at the beggining it was fine and dandy at 1.3687 Vcore LLC enabled (orthos large FFT's mixed test for more than 2 hours), but after some time, that didn't do it, so I had to put it up a notch.

Now looks good, seems to do the work.
I noticed that if I go up with the NB or the VTT or both, is unstable, but most people needs much more voltage to get it to work, mine is fine at those settings.

Well, now, I wanna go further, my goal would be 4.72 Ghz (FSB 1889 Mhz) and ram at 1700 Mhz 7 7 7 20 2T unlinked. But, it's just imposssible! I mean, I tryed everything for the last 4 months and I can't get it!
Soon as I go over 1800Mhz, tests fail. I tryed to set it at 1842 Mhz, to get 1700 Mhz on ram (wanna round number there) but nothing, even less that that, no matter what, nothing works over 1800Mhz
I know u must be thinking, Dude! that's more than enough, leave it there! but u know how that is, I wanna squeeze it till the last Megahert

So, any advice, setting, question or answer u may have or some way to enlight me, it would be more than welcome!
I tryed Lots of NB over 1.6, lots of VTT 1.36V, even 1.5 Vcore for a little period of time but nothing, no matter what.
Also tryed every BIOS available, the best for me is 0901, and that's what I have currently set up.

So, there it is, sorry for such a long post, but I run out of ideas

Thx in advanced!
