Why is my 7800 GTX so slow?

I'm running 3dmark03 at 1600x1200, 4AA, and 8AF. I'm getting about 6200. The review I look at show a 7800 GTX getting around 9000. What gives? I'm not overclocked at all, and I'm running an AMD 4000+.

I do have the connector hooked up to the end of the card, with a four pin PSU connector in each of them..

I thought it used a 6 pin connector.

What's the rest of your specs?

I use the six pin --> 2 4pin converter because my PSU doesn't have a six pin.

At first I only had one plugged in (out of the 4 pin slots), so I tried plugging both in and it didn't change anything.


I also have 1GB of crucial ballistix PC4000 RAM. When I get to the windows XP login screen the LED display on my AX8 Abit motherboard says "FF"...

It could be a number of things. How many AMPs does your 12V1 and 12V 2 rail supply? There are alot of people posting in other forums about similar issues and many of them are finding out that their PSU isnt supplying enough clean power. This can cause huge stability problems.

LOL @ Bungholios! :lol: 

I'll use the standard copyrighted reply...

The reason your score is low is because you're a bad person, take it personally because it's all your fault. :wink:

No go play a game! :tongue:

i would change the power supply, i dont think its a high quality psu and i think its getting stretched personnally, also do a clean OS install with fresh drivers then tell me what you get, you could be suprised with ur score.

I doubt anything at all is wrong with your card.

If all the above fails tell me the below \/

Please tell system spec and card spec.

My benchmark scores for Doom3 and Aquamark are spot on

My benchmmark scores for 3dmark03 at 1024 rez is spot on. The only thing that's off is my score for 3dmark03 at 1600 rez 8AF 4xAA...

So I don't think there's a problem with my system I guess as most other stuff seems normal...but any idea why that one test would do so poorly?

What size monitor are you using?
July 29, 2005 2:56:20 PM

Why in the world would the monitor size make a difference?
July 29, 2005 3:37:46 PM

The monitor might have a larger than 1600x1200 native....wise ass
July 29, 2005 3:48:37 PM

A) that would be assuming that he's using an LCD monitor, and I'd be surprised if you'd find one that's larger than UXGA for under $2000, in which case he should really be asking about SLI'ed 7800s
B) I still fail to see why it would possibly affect his score, even if the above scenarios are true. That's a monitor HW side conversion that takes place (if I remember correctly), in which case the score shouldn't be any different than if he was using a UXGA native screen.

Of course, if you're just being sarcastic, I apologize :p

My GTX is pretty slow too. It's on dell's back order right now. For the inconvenience I'm getting it for 400. I hate dell. 5 weeks w/o a comp isn't worth this.

That's actually tom's review.

Runs out. Spends big money on new vid card. Top of the line. And lo and behold. The stinken Bungholio marks. are way to low. What's a poor chap to do????? Wait for the next new vid card to hit the streets. Maybe those Bungholios will be better. :smile:
