Could my GPU be faulty or is it my PC?

Hey I'm new :)

Basically; I have a Sparkle GTS 450 1024MB DDR3 Card (SXS4501024S3NM); however the performance is nasty; especially compared to other cards. I know DDR3 will limit the card even thought it is on a 128-Bit bus but it feels like it's running more like a 64-Bit POV Model :heink:

3DMark06 it only scores 7600+ and Vantage only 4,000 but other users manage to crack 14,000 on 06 and 8000 - 12,000 on Vantage :pfff:

I've also noticed in GPU-Z and nVidia Control Panel the Shader Amount, Clocks and Bandwidth are totally different to the site, lower in fact so I'm curious if my card is a duff or my PC is having something to do with this :non:

I only really use this to play old games like Unreal Tournament 3, Sims 3, Dawn of War II etc etc

My PC:
AMD Athlon 64 X2 6000+ @ 3.00GHz
2GB DDR2 667 Ram
120GB Sata II HDD
Sparkle GTS450 1024MB DDR3
Windows 7 Professional 64-Bit
BETA Drivers: 295.51
600W Corsair GS600

GPU Z Readings:
ROPs: 16
PCI E: 1.1 x16 @ x16 1.1
Shaders: 144 Unifed
Pixel Fill Rate: 4.2 GPixel/s
Texture Fillrate: 16.8 GTexel/s
Memory Type: DDR3
Bus Width: 128 Bit
Memory Size: 1024 MB
Bandwidth: 16.0 GB/S
GPU Clock: 700MHz
Memory: 500MHz
Shader: 1400MHz

Clock rates advertised for the 2GB Model (basically same as mine but double the Memory).
Core Clock: 783MHz
Shader Clock: 1566MHz
Stream Processors: 192 Processor Cores
Effective Memory Clock: 1200MHz

I can attach any Screenshots or give more information if needed :) Would like to know if this card is actually preforming right or something is wrong :)

More about could faulty
  1. I don't think the card is an issue. The GTS 450 isn't a high end card. In fact, it's a bit down the hierarchy chart:,3107-7.html
    It's performing as it should, but it needs a good CPU and fast system memory to help it.

    More than likely, the combination of an anemic processor and only 2GB of system memory and trying to run Win7 x 64 Pro is hampering your score... and your gaming framerate.
  2. Sparkle got back to me; it is infact clocked lower with less Shaders then the standard model; apparently a "OEM from a different area". Apparently my System is fine but I took it back to Windows 7 Home 32-Bit as I had a disk spare.

    Pretty disappointed I ended up getting sold a non standard as I was hoping to put it in my new PC I'm currently building. Still plays older games such as Unreal Tournament 3, Dawn of War II and Sims 3 at a healthy 40 - 60FPS (and up to 80FPS if I clock the Memory to 650MHz via MSI Afterburner) in Medium Setting at 1080p 1804 x 1014 so it's still usable.

    Cheers :)
