Bottlenecked GPU?

I've been slowly upgrading parts of my computer and no matter what I upgrade it never seems to increase the performance of my machine in games.

Specs:

Processor: AMD Phenom(tm) II X6 1055T 2.8 GHz
RAM: 2046MBs - 667 DDR2
GPU: ATI 5870 1GB DDR5
PSU: 750W
Motherboard: M2N68-AM
HDD: 320GB 7200 RPM
OS: Windows Vista 32 bit

After upgrading the video card twice (from a 8500GT to a 9500GT [not knowing they weren't gaming cards] finally to the 5870) I upgraded the CPU from a 2.6GHz Dual to the 6 core and noticed next to not improvement in the performance in games as well as general usage. I thought at first it was a CPU bottleneck so that's why I upgraded the CPU, but now that I have that CPU which should be more than enough (right?) I'm thinking it's the RAM? Though I heard that RAM shouldn't have that much of an affect on graphic performance in a game.

Games:

WoW: ~18fps with shadows on - 30 fps without shadows, everything else maxed.
Starcraft 2: ~45fps Everything maxxed - ~90fps Everything low, in Sotis (like Dota) pretty graphic intensive

  1. What resolution did you play at?
    What about the other games?
  2. I play at 1280x1024 and I don't really play many other games. I play MW2 and it seems to run smooth but it doesn't look all that fantastic even with everything maxed...
  3. Upgrading the ram would help to 4GB DDR2.

    Download CPUID and make sure the motherboard has reconigsed the CPU and is clocked and working correctly. (Sometimes disabling Cool 'n' Quiet in bios helps with speeds, similar issue with my fathers Phenom II 955BE CPU, was slow on everything, disable cool n quiet and seemed to speed up everything)

    Ay 1280x1024 you will get very minimul frames boost even with the best system out there. 1600x900 (and the equivilent) is perfect for your setup with everything High to Maxed
  4. WOW, HD5870 at 1280x1024 is too overkill. You can maxed out everything with only a single GTS250... :)

    Well, low resolution is more CPU demanding than GPU.
    How many sticks are installed on your system? just one? or two?
    If you only use 1 stick of RAM then add another 1 stick so they will work on dual channel mode, make your system faster...
  5. I know it's overkill lol. I have 2 1GB sticks in there.
  6. Something else I noticed but I'm not to sure of is that only 2 of my CPU's cores are running? Looking at this PC Wizard thing it says only 2 of the cores are running and the other 4 are at a constant 0%
  7. It could be your CPU, you can test your CPU with software like Everest or Prime, somekind like that, i never use them....
    Still on warranty? You can RMA it if it's true that your cpu is in trouble...
  8. Yeah I just purchased this CPU today so it's still on warranty.

    What exactly do you mean post a screenshot of my cpuz?
  9. Agree that your RAM is a bit low. Which monitor do you have?

    He meant, that download CPU-Z, install it and start it up and post a screen shot.
  10. download CPUID and it will give details of your hardware installed. Tjis will give us a better understanding of the installed hardware

    But I still believe that:

    1 - Too low of a resolution to get anything better than the FPS yoru getting now
    2 - The Ram is struggling with your CPU and GPU, this needs to be upgraded to 2x2GB Sticks of DDR 800mhz
  11. How many cores do you see in Task Manager? The M2N68-AM supports the X6 as of BIOS version 0603, so you should be fine as long as your BIOS is up to date.
    As reccy suggested, download CPU-Z and check that your system recognizes the CPU correctly. Also, make sure that the CPU and the video card go to full clock speed while you are busy gaming. CPUID and AMD's Catalyst Control Centre should be useful here.
  12. CPU-Z version 1.55.2

    In Task Manager there is only 2 Cores showing.. MY BIOS is up to date. I just remembered I have Crysis so I'm about to start that up and I'll tell you the fps in that.
  13. In msconfig boot tab under Advanced options how many processors are showing?
  14. I've checked there and it's 2 and there's no option to select 6, it stops at 2
  15. Sorry to be annoying but how do you post a screenshot onto a post?
  16. I'm downloading BIOS updates now and I'll try downgrading it.

    Did you reset the CMOS when you changed the CPU?
  18. Uhh... What? Lol. Sorry, I'm not the best when it comes to this stuff
  19. I will try these things now. Thanks guys

    Clearing cmos means removing your mobo battery and then installing it after a minute.I dought it would help downgrade the bios first.Try cmos clearing as your last resort.

    It can also require the moving of a jumper from open to closed and then back to open again.
  21. Quote:
    Not all board has jumper.

    No, but for the ones that do removing the battery may not clear the CMOS just reset the time and date.
  22. Removed the Battery, used the jumper, downgraded and upgraded BIOS and it's still running on 2 cores....
  23. Either your motherboard is not as backward compatible as it's supposed to be or it's broken or the CPU is faulty or it's all three, take your pick.
  24. Oh yay... So I don't have the money to buy a new motherboard/ram to go with it and the CPU could be totally fine and sending it back could be the wrong thing to do...
  25. The only thing to do is RMA your CPU for another one to make sure the CPU is working fine. If you get a new CPU and it still produces the same details as above, then i think your motherboard is faulty/cannot reconigse the 6 Cores the CPU can allow.

    Teh thing is alos, you will have to eventually upgrade your RAM and Mobo. I would start with Mobo, if you have a budget of 50-70$ you would get a half decent Mobo which is defo support by your chip.

    Your RAM is old, but would still be supported by a AM2+ Mobo with DDR2 Slots. So effectively you upgrade one thing at a time.
  26. I would say RMA the CPU, then retest after reseting the BIOS again.
  27. I have another computer I can try it in. I'll chuck it in there as soon as I can and see how that goes. *fingers crossed*
  28. Took my machine into a computer shop today and they said my MB should be able to handle it but it can't so I need a new one. So it looks like I'll have to try and find 200$ for a new MB and some DDR3 RAM. Thanks for everyone who tried to help me get this thing sorted out, your help was greatly appreciated.
