Overall loss of performance after upgrading PC 4870 - 6850

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.

More about overall loss performance upgrading 4870 6850
  1. id return that card while you can .......despite the massive numerical difference that 6870 is only i notch above that card on TOMS card hierarchy!!!

    http://www.tomshardware.com/reviews/best-graphics-card,2964-7.html
  2. and if your 4850 is an x2 card that would explain the drop.....
  3. 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.
  4. It could be a power issue. The PSU could be weak and causing the CPU/GPU to throttle. Even if the GPU was not running well, it wouldn't drop your CPU score in half.
  5. try your old one....see what happens
  6. 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:

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817371033&Tpk=antec%20380

    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?
  7. be quiet makes GREAT psu's
  8. ooohhhhh dont dbble post
    he gets mad
  9. oh and disable that c1e in your bios....that may help

    prolly not tho.....it should throttle back up when called for
  10. 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
  11. ^badtaylor: what voltages did you use to get your chip to 4.3ghz, that is a nice oc even though it is a 975 to begin with, just curious
  12. 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:
  13. ^ 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
  14. 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.

    Your double posting is beginning to annoy me so please use the edit function, I know you know where it is.
  16. have fun solving your problem then, your psu is ***

    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.
  18. 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.
  19. I've already put everything back to stock. In Mafia 2 - around 10 fps less. In mw2 the same crap.

  20. 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.
  21. Ah yes, I should have thought of having you check. I know I always check that with a new card, but seeing your lowered CPU scores threw me.
