BeQuiet Dark Power 550w
Gigabyte GA-MA 770 UD3
Gigabyte HD 6850 OC
AMD Phenom X2 @ Phenom X4
2 x 2 GB DDR2
Creative X-Fi
Windows 7 32-bit

I’ve replaced my 4870 graphic card. Should be better and it’s not.

In Mafia 2 - 5 fps increase..
In Modern Warfare 2 I get serious fps drops to 20(!!!) in some places on maps. Before, on 4870 never had less than 60 fps.
That’s not the end – I get worst Passmark results in comparison to other PC with the same graphic card and CPU. 3d mark 2006 gave me half the points for the CPU, than on previous graphic card.

Things that I already tried:
- reinstalling drivers, chipset and graphics. Installing older graphic drivers, different graphic settings both in game and in AMD VISION ECC.
- finally format c, new system and drivers installation, and it’s still the same. Thought it may be because of changing my CPU to X4, but it was ok on 4870. CPU was tested for few hours with different cpu stressers and it was all ok. Never more than 48 celsius.

Bios photos below. Please help.

First of all it was 4870, not x-2. Sapphire Vapor-x. Second of all why do you double post?

I will not get anything better for that money.
I just want my computer to run as smooth as other with the same specification.
 
sounds like a sketch psu even though the 6850 does not draw much power. Get a reliable psu from a reputable manufacturer like antec, corsair, xfx, or seasonic, imo this is the hot ticket right now, it will run your system with power to spare:

I run a backup rig with an oc'ed amd quad and a 6850 with that antec earthwatts 380w psu and it is silent and flawless.


....also what are the clock frequencies of your cpu, and your monitors native resolution?
 
from the reviews ive read bequiet does not make good psus, and you can throw nzxt in that catagory as well, not a smart buy to save a couple bucks, OP needs to get a psu from a reliable manufacturer, also consider degredation and loose voltage regulations that ould cause failure or underperformance, basically I doubt that thre OPs psu is providing the specs that it claims to be able to provide. With the given info id say replace the psu and install win 7 64 bit, he has 4 gigs of ram

1.481250......and ive since pushed it to 4422 and not only got a cpuz but ran burnin test without bsod'n

but ive been runnin it @4113 on stock volts for normal usage!!! :sol:
 
^ nice how about an elongated in game stress test?, that is usually where mine would conk out on stock voltages at 4.0 ghz it would be stable for the first hour or so then after that it would crash, temps were fine but ive been anti-voltage increase up to this point, really no need but always looking for more power, thanks for the info

Oh please.. I need some real advice, not like "buy reliable psu" when BeQuiet is a very good, well known company that makes PSUs..

Why do you need my monitors nativer resoluton for??!! CPU - 3,21 ghz.

Few minutes in MW2, 1920x1080, mid settings:



In open spaces FPS drops to 20, when looking at ground it raises up to 70-80.

tsktsktsk. Bequiet uses FSP platforms IIRC, which is used by most mainstream OCZs and a couple Antecs; not amzing like Seasonic builds or better CWTs, but still respectable nonetheless.

Do you have powerplay enabled? Try disabling in in CCC and see if it helps.
 
After installing the new card, his CPU (not just GPU) scores are half in 3dmark. That would definitely suggest something besides the GPU causing problems. Perhaps you should put everything back to stock and see how things do. It might even take stress off of the PSU if that's the problem.

Sry for double post but I couldn't edit previous one.

Solved. PCI-E was @ x1. Removing and pluging card again, or replacing power slot for the cable in the PSU worked.

In MW2 I don't get less than 85 fps, and now it's PCI-e 16x like it should.

Greetings.
