Computer Performance issues

[ryokinshin]

Alright first my specs:
Manufacturer:
Gigabyte Technology Co., Ltd.
Processor:
AMD Athlon(tm) 64 X2 Dual Core Processor 6000+ (2 CPUs), ~3.1GHz
Memory:
4GB RAM OCZ Sli
Hard Drive:
713 GB Western Digital Greenpower(1 TB)
Video Card:
ATI Radeon HD 4850 Series
Operating System:
Windows Vista™ Business (6.0, Build 6001) Service Pack 1 (6001.vistasp1_gdr.090302-1506)
Motherboard:
GA-MA78GM-US2H

Now with regards to other parts, I've swapped and tested the CPU(changed it to a Phenom 2 X3 710), mobo, GFX card, ram, am testing the HDD right now and everything seems to be fine. I'm wondering if my OCZ ModxStream 500w could be the culprit of the performance loss. I've reformatted with XP, Vista 32bit and Windows 7 64bit, updated drivers and every other obvious thing I should do.

The low FPS problems would be getting lower then 30fps when running Crysis and Farcry 2 low, Battlefield 2142 around 30-40 fps, Neverwinter Nights 2 under 30 fps on low, under 30fps for Fallout medium.....you get the picture.

Harddrive finished testing and I ran into no errors, which means the PSU is the only part that has been untested.

No I don't get the picture. What's the resolution(s)?

 

[ryokinshin]

1280x800-1650x1080 for all the games, I tried both, but the performance issue is the same. Basically I'm getting performance issues when I shouldn't be and I've done necessary testing and updating.

That PSU should be perfectly fine for that system.

One thing I would REALLY check. Install Rivatuner, or ATI Tray Tools and turn on the monitor. Have it display your GPU and Mem speed. ATI cards have 2 profiles 2D and 3D. When you are not in a 3d game, the video card runs at a lower speed. When you jump into something 3D like a game, it bumps up to the rated speed. I've heard cases where the GPU gets stuck in 2D mode and causes this type of issue.

 

[ryokinshin]

The clocks seem fine.

 

[jay2tall]

So you verified that the 4850 IS running stock speed while in a game?

 

[ryokinshin]

Yes.

 

[jay2tall]

BF2142 should be at like 100FPS with that setup.

You said you reformatted? I would say check any background tasks that might be running.

Is your memory running fine? Maybe run MEMTEST

 

[ryokinshin]

Yes, everything is fine and I tried 3 operating systems with no background tasks.

 

[jay2tall]

Is anything overclocked? What video card is it? what speed if you RAM running at? I'd try running everything at stock speeds. If you memeory is like DDR2 1066 try it at the 667 speed or 533.

 

[ryokinshin]

I used a Sapphie 4870 and a MSI 4850 oced, everything is stock speeds otherwise, ram is 800mhz and I tried 2 different sets of memory, 2 different cpus, 2 different motherboards even.

 

[jay2tall]

Do you have the Onboard graphics turned off on the Mobo? Sorry im just throwing anything i can out. Sounds like you've already did alot.

 

[ryokinshin]

Yes, I have.
