GTX 285, bad performance.

Unfortunatly, at the weekend my 8800GTX kindly sacraficed itself so that I could get a new card without worrying if I was doing the right thing.

Before I continue on, I should probably list my PC specifications, these are:

Motherboard: Gigabyte P35C DS3R
PSU: Enermax Liberty 620w
Ram: 4gb DDR2 6400
CPU: Intel Q6600 at stock speeds
Hard drives: 4 of differing sizes and manufacturers.
DVD-RW drive: 1
Operating system: Vista Ultimate 64 bit

Now you know what my computer specification is, I can tell you that the card I decided to get was the BFG GeForce GTX 285 OCX, from OCUK.

Here is a link to the product:
http://www.overclockers.co.uk/showproduct.php?prodid=GX-085-BG&groupid=701&catid=56&subcat=1341

This was not my first choice, but they had none in stock of the one I wanted, so I chose this one last minute at the store.

I have gotten the card home, put it in my computer and booted into windows. From here I then removed the drivers from the control panel, and rebooted my PC into safe mode. I proceeded to run Driver Cleaner and removed everything Nvidia.

After this process was done, I booted back into normal vista and installed new drivers. Another reboot later and I was testing some games.

Crysis Warhead: barely gets over 30fps on all minimum settings.
GTA 4: takes years to load, and runs at less than 15fps. On the 8800gtx at same settings it was 30-40fps.
Tomb raider underworld: Again, less than 40fps where on the 8800gtx it was more.

From what I understand, the card is a PCI-E 2.0 card, and my motherboard only has a standard PCI-E slot. Would this be the cause of such bad performance? Is the PSU more likely?

I shall be installing Vista to another partition to see if the problem persists, and if it does, I shall be purchaseing either a new motherboard or PSU tomorrow.

Any insights would be very much appreciated.
 
hm, I don't think its the pci slot as i have that exact motherboard and just went from a 8800gtx to a gtx 275 with no problems.

could just be a dodgy card?
 
strange u sure its less performance then 285? maybe the card is daft or most likely not enough power but then it should be enough from 600w psu

I'm playing Crysis at all minumum settings no AA at 1680x1050 - 34FPS is the most I saw inside a small hut, outside it slows all the way down to 10-15.

defo something wrong there. Are you able to try the card in another pc?
 
Clock the CPU to 3.0 ghz and see if you get an improvement. Also check the core temps. Maybe its getting hot and clocking itself down.
 
Your probably right but it will put in a ceiling to his performance. Check the CPU clocks are not cutting themselves aswell. Also check that the settings are not being overridden by the Nvidia control panel.
 
Won't be the board, as i was running the GT on a DS4 which isn't PCI-E 2.0.

Could be the PSU as Psychas said, but only if its faulty, as it should power a 285 fine that, i know when my old PSU was on its way out, sometimes it took ages for XP to load, and also my drive would run a lot slower sometimes to, for example when running a virus scan, if it was fine it would take about 50 minutes, and when not it would take over 2 hrs, then it started rebooting all the time and struggling to load till i turned it off for a bit.

I've just done some more test:

I've re-installed vista, which had no effect.

I have used a molex - 6pin adapter and connected that to the card. The place I was getting 12-17fps in Warhead, has now gone up to 28-32.

I assume this means it's the PSU's fault. Unfortunate as I've only had it for about 6months where it replaced my old one which decided to go blowey uppy.


Edit: What would be a suitable replacement which will run these no problems?

Edit Edit:

Is the Tagan PipeRock TG700 good enough?. This is the one:

I'd rather prepare for the future, than have to buy a new one in a year or so.


Edit edit edit:

Thanks for all your help and insights people.

It is modular yes, but where would I get a cable from?

I've just swapped it round to the original wires again and performance is back up a bit.

25-30fps in that same area, but with all settings on Gamer this time.

I'll settle with that for now, and see how it goes in the next couple of days, possibly fiddle around with cables some more.
 
I'm a silly goose. I've done some more tests with cables, and it appears the card likes them in a certain order.

I switched them to how they were originally, and was getting bad performance again, switched them around and it's all good!
