Hi all.

I'm having problems with my 7900GTO from MSI, I'm getting 3200 3dmark 06 1.02 when I should be getting 5000, and 5000 3dmark 05 when I should be getting 10000. I have a 4300 @ 3Ghz, 1MB RAM.

I get 1232 SM2.0 when the VGA charts say I should get 2226 with a 7900GT and 3006 with a 79000GTX.

I am using 93.71 drivers, same results with 91.47 and 93.81.

All at 1024 x 768 resolution. Card is about two weeks old, only recently started benchmarking it.

Under the info on the nVidia control panel it says the card is on PCI Express x1, but it should be x16? Is this the problem? How could I fix it?

Thanks for any help!

if you have 1mb ram then your score is way too high im afraid

If your board has sli, maybe try sticking it in the other pci-express slot, dunno why it would only run it at 1x mine is at 16x. You sure it's definitely in the right slot (probably a silly suggestion as I'm not sure if they actually fit in regular slots)

Have you checked out the power to it? usually thats the biggest problem. Might also wanna d/l Riva tuner and see what your clock speeds are.

If you havent connected the external power connector it will throttle and it could potentially damage the card (so I've heard, not willing to try it myself as I have no reason to). Often it will tell you if you havent connected it tho.

D/l CPU-Z and check the PCI-E frequency, if it says 1x then try checking on the BIOS if you can change anything.

Should see some good benchmark scores on Jill of the Jungle though.

P.S. Maybe the expanded memory was not detected...

Roxor, the bios says my expanded memory is being detected.

Slim142, CPU-Z says Link Width x 1 Max Supported x 16.

randomizer, external power is connected, fan is spinning, I think you get a warning if it's not.

Xazax310, core is 650, memory is 660, which is default.

spanner_razor, I only have one PCI-E slot, no they don't fit into regular PCI, and the removal method is much improved over AGP.

Xazax310, I'm not sure 1GB RAM shold be affecting the scores all this much. It's 4.4.4.14 memory. 512MB on the card. Am I wrong on this?

Thanks for the replies everyone. I do have a problem then? ALso I can see the golden ends of the card sticking out of the PCI-E slot slightly, is this maybe the problem? I don't have any graphical problems though.

I did get occasonal errors with 93.71 with nv-disp.dll something, that's why I upgraded to .81, noticed the performance loss, downgraded, then went down to 91.47.

Do you think a full reinstall would help, as could it be a driver conflict from my driver experimentation doing this?

Thanks all! I will get Supreme Commander running at a decent rate, even if it kills me!

sweet, you're around, nice to see you

Anyways, what you were saying is probably the first thing to do, check inside the bios to see if it's accidently set at some weird setting, the op should try a cmos clear, or possibly a bios flash to see if that clears up problems. 90% of the time it will anyway

I just checked my cpuz, and mine says link width 16, max supported 16, so that means it definitely is under running the bandwidth. So as I said, check the bios to see if anything's configuerd wrong there, and flash it if you need to (if you do flash it though, try to use a flashing utility that most boards supply, if not, be sure to back up your bios on say a flash drive, most mobos can directly update from a flash drive in the bios if you can't get it to post anymroe)

Hey gang (and Tacos, recently arrived!)

Problem solved, thought you'd liek to know.

It was that my 7900GTO wasn't in the slot correctly (yes you shouldn't be able to see the gold ends!).

It was in enough so that it knew it was a 7900GTO in there, would work without any obvious problems, but was only running at PCI-E x 1 speed, which translates to about half speed.

Now I'm gonna 3dmark the beastie to see what I got.

Big gracias for all the help, you lot rock!

lol man, at least I can't see the gold ends on my 6600gt (which, is pimpin' beyond belief, I get 500000fsps in tetris man )

Anyways, congradulations on fixing the problem, I should have thought about reseating the card myself.

ps, I would think that running it at 1/16 the bandwidth would cause more than just a 50% performance loss, but ohh well

Nice to see you around too, hopefully im gonna be more active this days (since my rma again )

btw, nice to know that you fixed your problem and I would like to see the difference of 1x with 16x

did you finally get a good rma this time? I remember you rma'd, then the rma broke. Ohh, and I just bought a new keyboard I was going to get the logitech g15, but it was a bit out of my budget at $60, so I got an awesome ergonomics keyboard for only $30 after rebate

Well, PCI-E x1 gave me 5144 3dmark05 and PCI-E x16 10602 with 91.47 (93.71, 93.81 gave me slightly worse scores).

PCI-E x1 gave me 3207 3dmark05 and PCI-E x16 7282 with 91.47

It didn't quite work out to a sixteenth!

yeah, that's strange, I would have thought otherwise, looks like the 79000gto just can't take full advantage of the full bandwidth. Perhaps the 8800gts and gtx can, but if they don't, then I see no point to the upcoming pci_e 2.0

Gee I thought those were pretty good scores Tacos? It's about what the 7900GTX was getting in the VGA charts, and I haven't overclocked it!

(yet!)

They are getting good scores, but what I'm saying isn't the scores, but how much use the card can actually make out of the bandwidth and whether pci_e 2.0 will be of use or hype for a couple of years

How can we tell if the bandwidth is completely being used or not?

well, see you ran your gpu at full bandwidth, which is 16 times as much as the min, and min bandwidth, and your results were only halfed. One way you could check it out is to run it at 8x bandwidth to see if it's just the optimising drivers, or if the card simply isn't using all the bandwidth that is provided to it
