Club3D GeForce 8800 GT, and PCI Express runs at x4 speed? - 2008/05/30 01:54Hello, I'm having a problem with a Club3D GeForce 8800 GT card. The GPU-Z program reports that the card is working at x4 speed and connected to an x16 slot. I've read the motherboard manual and it tells nothing about the x16 slot speed, I assume it is capable of running at x16 speed. What's the usual source of this problem?
I thought, the motherboard only has PCI Express 1.x mode, maybe this can be fixed with a newer BIOS version, and were comes the second problem. I've tried the 62.92.27.00.00 available in the long thread about the GeForce 8800 GT and PCI Express compatibility. I used NiBiTor to check out the differences between the two BIOS's, besides the vendors ID's, some memory parameters were different. I change then to the values of my original BIOS, but after flashing and rebooting, I immediately saw corruption.
I also tried the original 62.92.27.00.00, the original EVGA 62.92.24.00.01, same result. Flashed back the original BIOS, no corruption. This version doesn't have speed fan control and reporting, I also can't read the temperature. Any thoughts?

Re:Club3D GeForce 8800 GT, and PCI Express runs at x4 speed? - 2008/05/30 09:51Why do you guys always think that it is the BIOS of the graphics card that is or would be causing the issue? Quite frankly I see a lot of persons just flashing their graphics card thinking something is wrong with it when there isn't. If you are seeing that GPU-Z show the PCI Express is running at x4 setting, than you might need to check first if it isn't the mainboard and to make sure you get the latest version of the mainboard BIOS flashed first. Secondly can you try your Club3D in another computer, maybe from a friend to see how it behaves there?

Quite frankly I see a lot of persons just flashing their graphics card thinking something is wrong with it when there isn't. Because it's the easiest thing after flashing the mainboard and trying to change some of it's settings, which I already did. It's quicker than reinstalling windows. The BIOS thing was a shot in the dark, I thought a newer BIOS would give better result in a PCI Express 1.0a mainboard, although it's an Intel chipset. But from what I tested it could be a sub-revision and doesn't work with the BIOS of other revisions.
Even though it's a 62.92.16.00.05 the date in the BIOS is 20th March 2008, I've compared to the Club3D GeForce 8800 GT BIOS on the site, and at least the signon is different. Oh well, I'm going to try it in another computer. Thanks for your answer, I'll report later.

Indeed, though it would not have solved the issue as it is not a PCI Express compatibility issue what you are experiencing as the card is working fine. This is more like syncro issue between the PCI Express slot of the mainboard and the interface of the graphics card, and that is not controlled by the graphics card BIOS really. So yes try in another computer and let us know the results.

Re:Club3D GeForce 8800 GT, and PCI Express runs at x4 speed? - 2008/05/30 15:25Well in another computer it worked fine at x16 for the PCI Express interface. This was an ASRock mainboard, more specially the Conroe945G-DVI which comes with an Intel 945G chipset running Windows Vista with the ForceWare 175.16 drivers. Weird, as this mainboard has the same chipset, but works at full speed. Suggestions?

It confirms what I had said before and that is that there is nothing wrong with the graphics card really as it works just fine at x16 on the PCI Express interface. Since it is the same Intel 945G chipset which is used on both mainboards I can only think of a setting in the BIOS of the mainboard somehow...

Re:Club3D GeForce 8800 GT, and PCI Express runs at x4 speed? - 2008/06/06 00:04Did you find anything out on the mainboard itself related to the BIOS setup of it? As I said I would somehow believe it would be linked to a mainboard setting that is narrowing the PCI Express somehow, or the software is not reporting it correctly. Have you also checked with other software what those report of the PCI Express interface setting?
