New computer - Radeon HD 7850 - only problems!

Hi,

I recently built a new PC and I am kind of disappointed about the gaming experience on this computer.


- Battlefield 3 is not starting at all
(just a window saying it would start the game, then a spinning wheel for 30 secs, then nothing)

- Mafia 2 stutters (wtf?)

- Skyrim has graphic bugs or just kicks me out of the game.


The only game that really works smoothly is Anno 2040, Diablo 3, Left 4 Dead 2.

So, what is wrong here?
Is that what you can expect from an AMD graphic cards, or am I doing something wrong?
I have the catalyst drivers 10.3 installed
(actually 10.4 I think, but it still shows 10.3 – seems to be a bug).


My setup:

16GB (2x 8192MB) Corsair Vengeance LP Black DDR3-1600 DIMM CL10-10-10-27 Dual Kit
1000GB Western Digital Caviar Black WD1002FAEX 7.200U/min 64MB 3.5" (8.9cm) SATA 6Gb/s
2048MB Sapphire Radeon HD 7850 OC Aktiv PCIe 3.0 x16 1xDVI/1xHDMI/2xminiDP (Retail)
ASRock Z77 Extreme6 Intel Z77 So.1155 Dual Channel DDR3 ATX Retail
Intel Core i5 3570K 4x 3.40GHz So.1155

  1. Why do you have 16gb of ram on windows 7 32 bit? I am pretty sure 32 bit only recognizes < 4gb. Maybe thats your problem.
  2. Try getting windows 7 pro 64bit.
  3. You have 2 year old drivers. There is your problem. Install the latest 12.4!

    ok, I am sorry, that was a typo.
    I actually meant 12.3
  5. Is there any reason you're running 32 bit windows? You know, out of your 16 GB, windows can actually only use 3.25 GB atm.

    Also, you have never mentioned your power supply.

    Would you mind running Prime95 stability test and Furmark burn in test? Testing memory you be a good idea as well (www.memtest.org).

    ok, I also thought about that.

    but do you really think that battlefield not starting and skyrim crashing could be because of that?
  7. Windows uses around 2gb so that does not leave a lot for your games. When i run skyrim the memory is at around 4.25gb.
  8. Might be. AMD clearly states that system requirements for HD 7850 is 4 GB of system RAM:

    http://www.amd.com/US/PRODUCTS/DESKTOP/GRAPHICS/7000/7850/Pages/radeon-7850.aspx#2

    And with 32 bit system you don't have that.

    BTW, when you run out of memory, games crash. And battlefield alone uses over 3 GB RAM.
  9. It could be the low RAM suggested but it also could be a bad GPU, not enough power or high temps, what PSU do you have and what temperatures do the CPU & GPU run at under load?

    PSU:
    750W be quiet! Dark Power Pro P9 80+ Modular

    CPU temps:
    around 30 to 35 celsius.

    GPU I have to check ...
  11. That all looks OK so far so its most likely the lack of RAM but try using HWMonitor to check all your temps from http://www.cpuid.com/softwares/hwmonitor.html
