BFG 8800 GTX Nightmare

Hi guys,

System Specs..
* E8500 Oc to 3.8(C0 stepping) cooled with Arctic Cooler Freezer Pro 7
*Asus P5K Premium WiFi Ap (using onboard sound)
*BFG 8800 GTX OC
*2Gig Corsair DDR2 1066 (twin2x2048-8500c5d g)
*BFG 800W PSU
*Samsung SpinPoint 250Gig
*CoolerMaster Stacker 810 Case with 4 X 120 & 2 X 90 Fans
*2 X Pioneer DVD RW (sata)
*Panasonic 42" Plasma and or 21" Viewsonic CRT Monitor

Heres our problem we play racing sims/games e.g GTR, GTR2, GTR Evo, Colin Mcrae 2 to Dirt and NFS 2 to UnderCover, we have never been able to play any of these games smoothly since we upgraded from an ATI X1950 Pro.
We have tried every Nvidia driver from a 97.?? to the latest 195.?? all done with fresh installs of windows XP and Vista.
As well as the slow jerkyness we are getting a lack of AA unless we crank it up to AF X 16, AA X 16 with multisampling but this just makes it unbarebly slow.
We have had the 8800 GTX OC for about 2 years and have still not managed to get any sort of desent frame rate at good quality.

Please help!!!!!!!!!!!!!

  1. Did you try with everything at stock speed? You're overclocking the CPU, RAM, and GPU. Also set your global settings to default in the Nvidia control panel.

    Your hardware looks like its enough for those games and you did a fresh install so it can't be a drivers issue or anti-virus or other background tasks sucking up your CPU cycles.

    Not sure how you could bear having a nice card like the 8800 GTX for two years and just watching it not work properly.
  2. I would have RMA'd the 8800GTX before, long ago.
  3. ^+1

    Since it's too late for that though..........................

    Check your cards temps. It could just be overheating. Downclock it, clean out the heatsink with some compressed air, and see if that helps.
  4. Hi guys thanks for the speedy replys, we have tried everything at stock speeds OC'd and everything in between, Our GPU temps average 49 - 60 ish. We upgraded from an X1950 Pro which was good we also tried different mobo (P5N-E SLI) different CPU (E6600) different PSU(antec true power trio 650w) also different mem , we wish we never down graded from the X1950 PRO.
    our system is dust free (inside case) , how do you rate the sapphire HD4670 1GB as thats all we can now afford now,

    So you're saying the 8800 GTX is probably broken or damaged? I would get a 4850 for about $90 before a 4670.

  6. we decided to tri something new, we put both our PSU's into the system the antec ture power trio 650 watt powering the 8800GTX only and the BFG 800watt powering everything else and we got no improvement it was a little worse, so we swaped them around antec powering everything and BFG only powering the 8800,and guess what we are getting a big boost in GTR 2 but when we ran most wanted the system crashed,

    and started emitting a beep to tell us there was no power to the graphics card, looks like we need a new PSU (a kick ass one) any sugestions welcome may not need a new card after all but thanks anyway,
  7. Well I don't know what is odd with your rig but I managed a Evga 8800gtx with my BFG9800gt in the same box with out any major issues with a antec ea650. So try a antec, enermax, or a any other high quality unit 650w or higher.
  8. we have a antec true power trio 650 watt and that doesnt run it very well,
    when we use vista a message comes up saying that the gtx is not getting enouth power, from the antec

    Well there is your problem, try enermax and they make good units and once ran my 8800gtx off a old 475w noistaker that was 5 years old. :o So I guess the antec unit that you got is crapping out or something else in the rig is draining power and starving the rest of the system. So are you overclocking the cpu and if so what voltage?
  10. Try putting the BFG 800w on the 88GTX alone and run the rest of the system off the Antec. 3x12v rails @ 19a should be able to support the GTX easily unless a rail or the psu in general is going bad. Have you tried switching around the 12v plugs or using a 4 pin molex to a 12v plug adapter? If all fails, even the the 800w-er, then something else is going on.

    BTW, how exactly is it performing badly? Stuttering, low fps, lock ups.

  11. we have tried lots of different combinations we are getting the best result with the 800W powering the mobo & 8800GTX, the 650W for everything else hdd, dvd, fans.
    we installed fraps ran gtr2, nfs most wanted getting good frame rates well above the 25(between 40 & 70fps depending on game) they say you need to have a smooth frame rate, but it is still stuttering.
    cpu oc'd voltage at 1.3625 we have also tried it at stock speeds.
    Also even tho we don't normally use it we installed 3D mark 05 ran it at default settings before system change we were getting

    Total;- 7135
    32.5
    20.7
    34.5
    Cpu 13706
    7.3
    11.4

    After sytem change(800W powering mobo & gpu) we got

    Total - 18972
    78.6
    66.8
    83.2
    Cpu - 17157
    9.2
    14.2

    but games still stuttering, no artifacts in games

    note all temps are good not sure about gpu temp tho anyone know how we could get a reading?
  12. Try and get a 1000w unit and things are still problem mating return the unit. Test the card in another computer.
  13. Still saving for new kit going to go with AMD & ATI next time around
  14. Very blatant sign that the PSU is biting the dust if everything was hooked up correctly.
    Try uninstalling your nV driver set and using Driver Cleaner; reinstall an updated set and check for the stuttering again - if it persists I'd say the 88GTX is damaged and the 650w may had something to do with it or the other way around.

    Check your CPU and GPU temps with Speedfan or Everest Ultimate. Riva Tuner can also monitor GPU temps.
  15. Should mention that (if you haven't reformatted and reinstalled between the 19xx and 8800GTX) there could be traces of the ATI display driver hanging around. Kill all traces of the ATI display driver if you see them in Driver Cleaner.
  16. every time we install a new driver we flatten the hdd because those driver cleaners never work properly, and the only thing the 650W is powering now is the hdd, dvd & fans the 800W is doing everything else.


    We had stalker- shadow of chenoble on last night and the 800W was whiening when under load. So it looks like we need a new psu (bfg sucks ass)

    Get one good psu perhaps a 1000w since there seams to be a major drain on your system some ware which isn't the 8800gtx but something else.
  18. Well that sucks... both PSU's?
    With all of the fans in your system take a look at both the Corsair TX750 and TX850 or some of the PCP&C models. They are high Q psu's with 80%+ efficiency with large single 12v rails. I am personally using a TX750 (60a on the 12v) with about 6 large fans (2 of them being 250mm large), 2 7200rpm drives in R0, a GTX 275, and have tried a 8800GT as a PPU, leds ect. Fine lil' PSU.
