I just finished putting together my P7N Diamond-based system and it has been very impressive and without issue thus far. However, I have a few "open items" that I will outline below...

The set-up:

MSI P7N Diamond, Core 2 Quad Q6600 (VID of 1.1625 in Coretemp ) , 8GB (4 x 2GB) OCZ Platinum Edition DDR2-1000 (2GB to install Vista and then to 8GB after SP1), 2x 8800GTXs in SLI, Auzentech X-Fi Prelude, 2x WD6400s in Raid-0 (OS & Files using onboard controller), 1x WD6400 eSATA (for back-up and using the onboard controller), 3x WD6400s waiting for a home (more on this below), Silverstone Strider ST-1000, Lite-On SATA 4x Blu-Ray Burner, Lian-Li V2000 Plus II and Windows Vista Ultimate 64-bit.

SLI in one blue PCI-E slot and one white PCI-E slot:

In order to save the lone PCI slot for my X-Fi Prelude, I had to use this set-up. They are connected with the one long sli bridge that comes with the board. I started the system off with both of them in the blue slots for comparison.

SLI in Blue PCI-E Slots: 3D Mark Score of 11,194 (no OC)
SLI in Blue and White: 3D Mark Score of 10,223 (no OC)

I played Crysis before and after the change at 1920x1200, settings maxed out and 2x AA and I didn't notice any difference (aside from much better sound from the X-Fi Prelude )

Question: Has anyone got their hands on two of the long bridges and hooked both of them up with the blue and white slot configuration? If so, was there any performance increase? If not, I'm going to be the first .

BIOS issues:

The CPU and Memory are not in the preferred 1:1 ratio. Is there a "quick and dirty" way to go 1:1 on the 1.16beta BIOS? I don't want to play with the voltages until I do all of my homework on oc'n the board. I have a great VID on this G0 Q6600 (1.1625) so I don't want to screw up and fry it before I get to put it on water...

The Plan:

I have 2x 120.3 Swiftech MCR radiators a D-Tek fuzion (with quad nozzle kit), 2 Liang D5 vario pumps and 2 EK full coverage blocks for the 8800GTXs. I'm going to order the Koolance "GPU" block for the NB but what do you guys think I should get for the SB, MOSFETs and PCI-E "sub-SB?" I'm going to transition over to water (modding the v2000 for the two 120.3s) and try to OC to 3.6GHZ.
