8800 GT IN PCI-E 8x

[skeletonw00t]

So how do i know if it will work in my board???

Strange that apparently an 8800GT performs WORSE than an X1950 at anything other than in a 16x lane.

There's plenty of people reporting that they work on older PCIe 1.0a boards, NF4 for instance. I'm sure there are individual board issues, but generally PCIe 2.0 is allegedly fully backwards compatible with 1.0a & 1.1

I did'nt say 1.0a though. I said 1.0. The budget Asrock boards and some others use Ver 1.0 which will not take a 8800GT without a bios flash on the GT to Gen 1. The bios flash as far as i know is just for Asus Gt's as well.

how do i find out what version pci-e i have?

 

[BassPunk]

x8 is surely to affect the minimum framerate you get with a 8800 series setup

how do i find out what version pci-e i have?

try 'Everest' and look under the 'GPU' section

 

[skeletonw00t]

All i can see with everest is:

Revision: A1

thats on the pci-e bit about my graphics card.

does a1 mean it will work?

Common mistake, 1.0 is 1.0a. Normal practise, first revision is 'a', hence the reason I used the term. You'll also find 1.1 occasionally referred to as 1.1a in the technical specs.

Or check ECN's (engineering change notice), the earliest pre release ECN's refer to 1.0a

So if 1.0 is 1.0a how come the 8800GT does'nt work in the Asrock boards? Is it because of the 4x Pci-e slot? Not nit picking, just curious now as i have seen quite a few posts on various forums about the Asrock/8800GT problem.

 

[LoadsaMoney]

I think the AsRock boards need their BIOS flashing to a later one to support the GT's, or the GT needs a BIOS flash, can't remember which now.

so will the 8800gt work in my mobo :s

There's 3 current revisions, 1.0a 1.1 2.0. Not including the recently announced 8GT/s 3.0

I've seen reports of a couple of boards not liking the PCIe 2.0 cards, not just Asrock. Likewise I've seen plenty of older boards work as well. Like I said, there are a few board incompatibilities. Who knows how they've implemented the specification. If they're fixed/fixable with a bios revision I've no idea. However generally PCIe 2.0 is backwards compatible. If you buy one and it doesn't work then you have a good case for a full refund.

so will the 8800gt work in my mobo :s

If you can't find a report of one working successfully, there's only one way you're going to find out.

Hope this helps.
