I should probably check if this will work...

Hey guys, I have been planning on fitting a GTX660TI in my Dell Precision T5400 (dual socket LGA771/DDR2 ECC Xeon workstation) and I never gave compatibility a thought. Will it actually work? :confused:

The system has 2x PCI-E x16 slots and an 875W PSU with 2x 6 pin PCI-E connectors.

If you are thinking that this is a strange system to fit a 660TI in, fear not, it is for folding while the rest of the system is busy doing other things.

No reason for it not to work, PCI-e is backwards compatible in the same way as USB 3 will work in a 1.1 slot, you just get less bandwidth.

Its not necessarly backwards compatibility that i'm concerned about.

The system only works with a Dell PSU, it only works with fully buffered ECC DDR2, it only works with matched Xeons of a specific stepping, so I wondered if it only supported certain graphics cards.

Dell annoyingly go through effort to make their parts less compatible. Throughout the years on several computer and laptop builds, they have tried using different connections, mirroring the motherboard tray of cases (so you need a mirrored motherboard and swapping around the standard PSU pins. Sometimes when some Dell parts fail, you will need to go to Dell and pay the premium for the only replacement available.

The PCIe slot isn't the one to worry about but rather the PSU pin configuration for the card. I would e-mail Dell to see if the PSU is compatible with GPU cards NOT sold by Dell.
