J&W P55 board openly claims SLI support

J&W's latest P55 board proudly proclaims its Nvidia SLI affiliation.

COMPUTEX 2009: J&W's upcoming P55 motherboard is the first we've seen proudly claiming support for Nvidia's SLI.

We already know the PCI-Express lanes come direct from the CPU for Lynnfield/P55, so the two PCI-Express lanes are physically x16 but only x8 electrically in SLI mode. In single card mode the upper most slot gets a full x16 2.0 bandwidth though.

J&W's board has some heavy cooling around the CPU socket for the eight phases, and also includes the extra slot connector for NAND Flash by the four DDR3 1,333MHz memory slots.

In addition, there is the usual of PCI-Express x1 slots, two PCI slots, onboard power and reset buttons and eight SATA 3Gbps - the two extra are from a JMicron chipset that also supplies IDE. The rear I/O gets a clear CMOS button too, but it's all a bit samey really.

Is this the limit of Nvidia's motherboard contributions in future? Despite this loud affiliation with Nvidia we doubt the two companies can really play much with the die hardware of Intel's CPU.

Let us know your thoughts in the forums.

doesnt only having 2 x8 lanes means no sli on the top cards? i know my 8800 GTX's need 2 true x16 lanes.

What company is J&W?

LOL for being "the leading motherboard manufacturer" I think this is pretty funny that their stuff isn't available world wide...

I think it's 2 PCi-E 2.0 X8 lanes.

And I might sound stupid, but who's J&W?

J&W's previous notable achievement was a 780G AM2+ mini-itx board with pci-express, which would be great if stores actually sold the thing.

Uh, nope, 88 GTX's should work fine on x8s.

8x of pci-express 2.0 = 16x pci-express 1.0...
The current graphic cards still don't use the full bandwith of pci-express 1.0, pci-express 2.0 only came out because (if i'm not mistaken) of the power requirements, as pci-express 2.0 gives more energy (w) to the graphic card

That's what I believe to be true; I've never seen any numbers to support the thinking that a single slot card can saturate the bandwidth of 16 PCI-E lanes therefore a PCI-E 2.0 8x slot for each should also be sufficient. If you think about it logically, J&W wouldn't risk having performance-deficit egg on their face.

What really annoys me is the lack of a physical 4x slot, or open-ended 1x slots to accommodate a RAID card with your SLI setup. :(

I believe power is the word you're looking for there.

There's always the dremel approach. =D

On that note, does anyone else remember the "cut to fit" hilarity from a few years back when PCI-E was still new? That still cracks me up.

I think someone at MSI read my mind... :)

J&W are a big OEM company - they make motherboards for other people that are sold as different brands, so most of the time you won't see J&W on the packaging if you buy one of their boards.
