Sandybridge for overclocking, two solutions review.

Multi-GPU scaling on MIVE

3DMARK03 (MIVE, 2600K D2, 5518Hz LS, 2x2G Kingston DDR3, Enermax 1250W)

Single 8800GTX - 45686

Two 8800GTX SLI thru NF200 - 67908

Two 8800GTX SLI by native SB lane split x8+x8 - 68582

So if you run 2-way it's wise to try avoiding NF200 bridge to reduce latency and have little better performance. All three tests with MIVE, coz UD7 don't allow have NF200 away if I recall correct

Full speed (x16 + x16) SLI hampered by the NF200!?!

[Edit: Asus web site reports; "Expansion Slots 4 x PCIe 2.0 x16 (single @x16, dual @x8, triple @x8, x16, x16 )"

So dual = x8 + x8 but triple = x8 + x16 + x16 ?

Am I missing something here? ]

I would love to see this re-tested with some more recent hardware (i.e. GTX480/580 or 5870/6970).

Damn you have a lot of tools!

Awesome write up
