NVidia GF8600GT 16x speed?

[Naki]

My motherboard has a NVidia NForce 4 SLI chipset.

It can run PCI Express videocards in 8x + 8x configuration (SLI) and single 16x. I removed one card, but the 1 card left still runs at 8x. Is there a way to fix that so it runs in 16x?

Thanks!

The motherboard CPU socket is Socket 939 (AMD). CPU is dual-core Opteron. OS is WinXP Pro. Videocard is ASUS GF 8600 GT 256 MB (fan version).

Which slot is rated for 16x speed?

Look it up in the manual. Plug it into that slot.

Both slots are rated for 16x. Card is inserted into slot 1. Problem is elsewhere.

Latest BIOS revision?

i doubt that your card even needs more than 8x, how do you know that it does? do some 3dmark tests maybe.

BIOS is latest. ripken204, yes, but I'm getting a new card, probably a ATI 4780. I do think that it will need the full 16x speed to run properly.

Yes you do. It might not make a big difference on the 8600GT because it uses less bandwidth, but on the HD4870 it does.

It seems (says so on ECS's web site) this motherboard (ECS KN1 SLI Extreme) can only work with 8x speed when working with a single videocard.

So I guess I will have to settle with 8x then...

Bought the Radeon HD4870 by Gigabyte with 1 GB of RAM + 500W power supply.

Card doesn't fit in my case. It fits without the power connectors, but when I plug them it, it won't fit... Will have to buy a new case tomorrow.
