Motherboards that fits 3 X nvidia dual slot cards

[dhvd79a]

So far I have only found a few MBs that look like they have spacing to fit 3X nVidia dual slot cards.

ASRock Z68 Extreme7 Gen3 http://www.newegg.com/Product/Product.aspx?Item=N82E16813157269

And several EVGA boards including;
EVGA Z68 SLI 130-SB-E685-KR http://www.newegg.com/Product/Product.aspx?Item=N82E16813188097
EVGA Z68 FTW 160-SB-E689-KR LGA 1155 http://www.newegg.com/Product/Product.aspx?Item=N82E16813188098

I didn't include the $300+ boards because I don't plan on spending that much.

Can anyone confirm that the listed boards will fit 3 X dual slots or recommend a MB that does?

Thanks

Edit: To be clear there will be no SLI. This is used for cooperative computing. I have all the parts to do this with 1155 except for MBs that will physically support 3 X dual slots.
I really just need confirmation that the above boards or some other suggested board will physically handle this and still be able to cool the cards.

I'm fuzzy here, are you looking for a '3-WAY SLI' Z68?

If so the 130-SB-E685-KR and is 2-WAY SLI, and the 160-SB-E689-KR and Z68 Extreme7 are 3-WAY SLI. Otherwise for P67: $280 GA-P67A-UD7-B3 3-WAY or $235 P8P67 WS REVOLUTION 3-WAY + PhysX.

Is there any particular reason for 'Z68'? And if I understood correctly why 3-WAY?

In an earlier thread I asked if there were boards that would run 3 discrete cards.

I already have the cards.
What are you using the cards for? Cooperative computing. Seti, Collatz Conjecture for example.(See Sig link).
Not driving Monitors.
Not gaming.
No SLI.


This is simply a platform consolidation and I need two MBs that function properly with 3 cards and physically handle 3 dual slot cards. The ones I listed are ones that appear to be able to handle 3 dual slot cards. Just trying to confirm that and get a better suggestion if possible.

8K+ posts, sorry I cannot remember -- add an Avatar makes it easier to remember. It depends if this is a hobby or you have a heavy computing load. Then it depends on the GPUs.

Cheaper - Independent 3xGPUs ASUS P8P67 PRO (REV 3.1) (x8/x8/x4) - http://usa.asus.com/Motherboards/Intel_Socket_1155/P8P67_PRO_REV_31/

$235 ASUS P8P67 WS REVOLUTION (x8/x8/x8/x8) - http://usa.asus.com/Motherboards/Intel_Socket_1155/P8P67_WS_Revolution/#specifications

Better - wait for the SB-E / LGA 2011.
Best - A real Workstation with Xeon, if the load is really high then multiple Xeon WS MOBO (Dual LGA 1366) and Pro GPU's. e.g. -> http://www.supermicro.com/products/system/4U/7046/SYS-7046GT-TRF.cfm?GPU=FC4

Best = $ MONEY $

Any LGA 1155 is more a toy for 'complex work.'

The PRO does not appear to have the slot spacing to add 3 dual slot boards.
The revolution looks like it would it would work but the way the slots are spaced I would expect serious cooling problems.
Xeon is not going to happen. I have all the parts I need to do this wiht 1155 except for the MBs.

Thanks for the response.

ASRock Z68 Extreme7 Gen3 LGA 1155 Intel Z68:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813157269
edit: costs: $274.99 and it has huge space between the 3 pci express (since it has 5 you can place them at 1,3,5)
edit2: http://www.asrock.com/mb/overview.asp?Model=Z68%20Extreme7%20Gen3
it has 3 slots between them in 3way setup, and as you said in your first post this is your best choice imo.
edit3: EVGA P67 FTW 160-SB-E679-KR 239$ after rebate http://www.newegg.com/Product/Product.aspx?Item=N82E16813188082

Again, my top choice is the ASUS P8P67 WS REVOLUTION (4 GPUs), and the ASUS P8P67 PRO is fine IF the GPUs are indeed independent (3 GPUs).

Look at both MOBO's carefully, the last GPU will be covering the connectors on the bottom, so the connectors need to be bent over at 90-degrees. ANY MOBO with 3-WAY or 4-WAY PCIe slots is going to have the problem. IF the GPU's are reference design then the air will be drawn from the front and exit out the rear of the GPU. You do need a good case with Front -> Rear airflow.

As I recall last night the GPUs are 9800 GTX - http://www.nvidia.com/object/product_geforce_9800_gtx_us.html
Reference design:

ASUS P8P67 PRO (REV 3.1):
