Low 3d marks with 8800 gt :(

Hi all

Finally got an 8800gt, I decided to run 3d marks today and the score I get is very disappointing..



Now this is barely higher than my 7900gto was. The card isn't overclocked or anything, the fan speed I manually turn up using ntune. I have vista home premium 64, surely that can't be causing such a performance drop can it ?!

I read through this thread here:

http://forum.overclock3d.net/showthread.php?t=19883

And from that I've been and changed my ram settings manually, up to 1.9v with a tRAS timing of 12. I checked to see if my graphics card was in the right slot. Unfortunately it is..

In games I get a reasonable frame rate improvement based on the old card, but not as big as I had hoped. The rest of my spec is in my sig.

Anyone have any ideas?

Cheers :)
 
Yeah it`s not right, job is now to find out why.

There was some1 on the abit forum who had 7k or so, switched slots and it doubled his gfx result. But u`ve checked that.

Are u`r bios settings good for pcie slot ?
 
make sure its in the right slot we had a full thread about this last week and that was the problem :P
 
Cheers guys for the input :)

SBB: I've been through and tried most of the nvidia drivers I can. I will try reinstalling the motherboard drivers to see if that helps...

Rast: In the BIOS the pci-e frequency is default 100mhz. The card is in the 16 times slot (blue). I had the same switching cpu frequency that hawkinsa21 had in thread I linked to, but that was sorted by turning some BIOS settings off and then overclocking the cpu very slightly and upping the ram voltages.

I will just try running '05 3d marks to see what we get.. In games it is a little slow. Crysis runs pretty much the same frame rates in high dx10 and high dx9.. which is a little puzzling. COD 4 runs playably at max settings, probably a little smooth if I knock the AA and AF down.

My super pi score is... 21 seconds to 1 million.
 
Swap the card's slot anyway, and see what results you get... I know some of them are very wierd
 
I may try sticking the molex into the motherboard.. I'm not sure if it'll make any difference. I used to have just the 4 pin 12v into the motherboard, but not I've got a new psu I've got the full 8 pin 12v, I doubt that makes any difference. Grrr.



I have the gpu-z shot here.. I'm not sure why my clock and ram speeds are coming up at 0hz.. Which is pretty wierd.

Also..

On the EVGA forum there is this thread:

http://evga.com/forums/tm.asp?m=176929&mpage=1&key=

Which has the new BIOS's for the graphics card to stop it from getting so damn hot. So.. I go and download the N801 BIOS for the vanilla card I have. I go to run it, following the directions and I can't get it to do anything. Which hints that there could be a problem with the card?

I'm not too sure at all.

Cheers for the input guys :)

EDIT: Apologies for the jumbo low res screeny..
 
did u have ur 7900GTO overclocked? try and see if that OC is still enabled anywhere

and deff plug in that 4 pin molex into the mobo
 
tried switching slots yet? And is it in the slot properly?

Could be a fault with the card.. the GPU-Z results look abit odd.
 
Right...

Maybe it's due to OS I'm running.. Vista Home Premium 64. I think I will remove all the nvidia drivers and start again from there.

No OC apps seem to work, ntune and rivatuner don't display and of the clock settings. Bizzare. I'm hoping it's not a problem with the card as it's going to be a pain in the ass to RMA over xmas and with stock levels so low..
 
I just got round to installing 3dmark06 pro, seeing as I has no web browser on the game pc.

With only the cpu clocked a bit, I`m getting 13806 on Vista Ultimate (32bit).

Switch out my cpu score for urs, u should be around the 12.4k area.

Doesn`t work exactly like that, but those are the rough figures.
 
Nick: Cheers for that I'll take a look :)

When I'm home next weekend I'll have a go installing XP and see what happens.

Cheers Rast and that's a rather nice score. How much ram are you running? I have 2 gig of XMS2, which was pretty cheapy but runs at 400mhz, 5-5-5-12. I'm not sure it could be that.. but I've only used Vista a week or so.
 
Doubt its anything to do with RAM. I was getting 11000 on 2GB CL5 PC6400 RAM, with a highly overclocked E6600 and 8800GTS
 
Nah it won`t be ram imo. I`ve got 4x1g dominator in it, and it`s not pushed cos I can`t trust the bios atm.

Imo, it`s definately down to the mobo->gfxcard relationship.

Without knowing any of the facts, some1 would say u`r pciex16 is running @ x4 or something. Either that or it`s underpowered.

I`m using an 8pin eps12v connector here, and connected the pcie power directly from the psu.

U could try using the power adaptor supplied with the gfxcard via 2x molex.

I`d be trying the mobo molex power too seeing as u have the 4pin 12v in the 8pin connection.
 
Just swapped the card in the slots and got this..



So I'm sure the top slot was the 16*. The 'Bus Interface' section on the gpu-z that says its a 4 times pci-e link, I'll check that it goes to 16 times when I refit the card. I'll have a nose around the BIOS, but I don't think there is anything there that I can change for the card.

I may stick in my old 7900 and see if it is similarly slowed or not. If it isn't then I'm pretty sure the card could be the problem..

Cheers :)
 
Yep indeed it did, that was in black slot, lower down. It's back in the top blue one where it was originally and the gpu-z readout is back to 16 times.

I'm going to reinstall drivers now. I really hope it works this time..
 
yea the other screenie u put it says X16 @ X16 so it looks like its going full speed

i dont think u should flash the bios on the card itself

im pretty clueless atm..
