TRI SLI Support Question

[StAndrew]

A friend is getting rid of his P6X58-E Pro moboard and I'm considering an upgrade. I have three GTX 780's and wondering if this board will support TRI SLI. The description says it does, but the bottom (white) PCI slot is only x4.

Link to Asus's description:

Any help would be appreciated.

Ok, I see that in the specs section, however, all the reviews I read said the white slot was only x4 :shrug: The third slot clearly is short some pins and won't be able to run at x16 but its hard to tell if its limited to x8 or x4.

The spacing of the PCIe slots is perfect for 3-way SLI and CF with dual slotted cards which will have some nice room between cards for air flow. The breakdown of the PCIe slots is; the dark blue slots are x16 with the lowest White slot being x4.

The P6X58-E Pro features a total of three PCI-E slots. The blue PCIE slots operates in x16 mode and the white slot operates in x4 mode, which can be handy for a discrete audio card or PIC-E solid state drive.

Ok, found and downloaded a manual; its says x8. Limiting to x4 didn't make sense to me. Oddly enough, Nvidia's Tri SLI support list didn't have the P6X58-E Pro (had most other P6X58 boards).

when that board came out you had to have nv200 controllers in the board to support tri sli but they changed it to only needing 8x or better slots since the nv200 made it slower. they also do not support tri sli on any current cards.
