GX2 Spacer kit
:D http://www.swiftnets.com/

Signal Hill, CA – Wednesday 11th, October 2006 - Swiftech™ today announced the release of the GX2 spacer kit for nVidia® GeForce™ 7950GX2 dual-GPU boards. The kit is intended to enable off-the-shelf water-cooling solutions for this board. “The 7950GX2 features tightly spaced PCB’s which forces overclockers and silent-computing users to purchase expensive custom cooling systems for it. With this kit, enthusiast users now have access to a low-cost solution utilizing off-the-shelf high-performance & low-noise water-blocks such as Swiftech’s MCW60”, said Gabriel Rouchon, Swiftech Chairman & CTA. While the kit precludes the use of Quad SLI configurations, the company feels that this solution will satisfy the vast majority of the target audience for this particular board.

The spacer kit is composed of a set of:
- 3 Male-Female 4-40 standoffs
- 1 Female-female pass-thru standoff
- 1 Female-Female 4-40 standoff
- 1 4-40 philips screw
- 1 extended PCB.

haha maybe now they will lower the prices for GX2's block..::hint..hint:: DangerDen..;)

Finally... Won't fit quad sli though will it? :(

This'll mean some killer overclocks finally for those cards.
Although I too worry about lack of space

Finally!!! :woot:
A solution to watercool my 7950GX2 with high performance bocks :)

Get the kit with two MP-1's. That'd perform great. :)

man its about time.

this also opens up the GX2 to Dry Ice and LN2 cooling now as well ;)

I think this might work in Quad SLI on a board like the Intel Badaxe, since it's got all those extra PCI EX Slots...
of course you need modded drivers and all... but while it definatly doesnt look like it would work on most boards, I think theres a board or two it might work with in Quad.

I do not think any of the quad SLI drivers have been hacked to work on 975, but someone did seem to get it to work on the P5W64 WS Pro, but it was not any faster than a single card

that is definately a smart idea. Kind of funny nvidia card manufacturers didn't think of this.

cuz it would kill quad-sli.

i am really liking this product from swiftech since it opens up a few possibilities to cooling this card. i fired of an email to swiftech on tuesday got a reply wednesday. my question was when watercooling and using the spacer kit like the setup in the second pic in post 1, how would i cool the pci-e splitter chip. the response i got was to use a ram sink though not included in the kit so my advice to any one else looing for an alternative to the dangerden gx2 block would be the spacer kit, and extra 8 ramsinks (1 for pcie splitter chip the rest on mosfets) and two mcw60s with ramsinks :P not a bad alternative

edit: the 2 mcw60s would be reusable for future cards since i doubt a dd gx2 block will fit any other config without mods

vote for longer flexible cables (30 cm), would make it possible to mount the 2nd board anywhere inside the case:slobber:

YESSSSSSSSSSSSSSSSSSSSSSSSSSS!
Gonna order it right now!
Now what block to get? Would a 7900 full cover block fit?
Need retailer other than swiftech. =/

Hoo-RAH!

Quad SLI doesnt really work. This + real cooling = win!

I still dont like the 8800, tho i`ll wait for performance numbers to reach the masses before making a decision

OOOOOOOH! This is what I've been waiting for!

Already at 650/700 stock cooling :fact: , can't wait to get this!

I wonder, for those without water cooling, which aftermarket air could fit?

Awesome! What many users have been looking / waiting for. Now if we could get a flexible ribbon cable... ;)

Anyone found one besides factory direct? Swiftech takes forever direct.

I want it.. now.

Yea I was looking around but couldn't find a retailer that carries it. I had to order directly.
Now to find MP-1s.

Think two Zalman VF900-Cu heatsink/fan combos will fit now?

That would be bad ass for us n00b air cooler people....but the only problem is that I am going to exercise my step-up rights with eVGA for some generation 8 GeForce goodness! :D

How long is step-up good for after you purchase a card?
10-13-2006, 12:05 PM

90 days if I remember correctly

Am i the only one that finds space probs in the spacer's design?
U can't use this card in the first pci-e slot unless your m/b doesn't have a NB chipset... :p:

Awesome find, I gopt y GX2 from EVGA stepup from a 7800GT, Paid 358 from the egg, and paid 600 for GX2 so I didnt have to come out of pocket that much for killer performance..

I have been waiting for this, now time to water cool this beast..

hopefully most people doing this will have 8x2x setups. Im with you its an issue but i dont really see any way around it.

But the pci-e slot(?) is on the bottom pcb, so this won't be a problem.

Also,with a different block on the top pcb, you might be able to bust some quad sli. Probably have to be a custom block, but i think it would work.

I wonder if they sell / will call out of that location? Got a branch office in Anaheim, could have someone grab one for me and ship it on over :D

I ordered today and they shipped today. Not that slow after all.

you would most likely have latency issues. the board was designed for the short interconnect and the timmings would probably go crazy if you make the cable too long. but then again, nVidia might have been cool enough to design it in such a way that the latency was not an issue (no idea how they designed it + im not an EE so I cant say which is correct)

I was wondering myself if even the short PCB extension would cause any loss in performance. I've no background in that sort of thing, so I can't speculate either way. My instinct is no, but hey..

Ha, i think i made a difference, the spacer kit now comes with a ramsink for the secondary chip (what ever the real name is)

No. The limiting factor on the 7950's is the max memory OC you can get with the slower 1.4 or 1.6ns that find there way on the cards. On straight water it is very easy to get the core OC well above the OC'ed memory bandwidth available to support that core speed.

sorry for asking you to go off topic a bit but what oc on the core would you consider to be limited by the mem, and if 1600 is the typical gx2 mem oc what core frequency is too much

wondering if it is worth the volt mods for core..

1600 memory perfectly clean in everything might be pushing it a tad. The GDR3 chips are not exactly stellar OC'ers typically. Part of that is NV tied the Vdd and the Vddq together off the same on-card power supply and GDR3 chips just hate the Vddq high. Some 1.4ns chipped cards might make it though.

With the memory running 1584 and the memory timings tightened up core clocks above about 690-700 didn't scale well and produced very little gain in test scores as the memory bandwidth becomes an increasing bottleneck. By the time you get to 726 core the cards no longer gain anything from increased core clock.

I've had no trouble pushing the cores well over 700 with ViperFang WB's at 1.55 Vcore.
