    Hi, I just installed a new BFG 7800 GS OC. The first 3 or 4 times I tried to power it up, I wouldn't get any image on screen and my 4 optical drive lights would keep blinking on and off. I tried securing the power and IDE cables and after 2 or 3 more failed attempts at booting up normally, it finally did mysteriously :eek:neeye: Now after I installed my drivers (94.71), I notice that one of my SATA drives is no longer being detected (I know its not driver related, I just thought I'd let ya know which drivers I installed). Could it be that my power supply is not enough for the second hard drive? I do have quite a bit of peripherals hooked up to my PSU (AS500W), 4 Optical Drives, 2 SATA hard drives, and 6 case fans. The PSU has 34A on the 12V rail according to its specs, and the requirements say you need 20A, so I didn't think that it would be a problem...

    Anyways, apart from not having my drive I d/l movies on anymore, the card is working exceptionally. I'm OC'ing it with RivaTuner to 475/1375 with the stock cooler and I'm not seeing any artifacts in Oblivion (1280x1024, Bloom, 4 AA, Most settings maxed, no grass) or 3DMark06, but ATI Tools gets artifacts at around 425/1275. My temps when fully loaded with fan speed at 100% running 3DMark or Oblivion never go over 61 celcius. So, I just wanna know, is that too high a temp or am I safe to keep OC'ing the way I am? Any help from any of you pros would be greatly appreciated. Thanks in advance.

    61C during load is actually pretty good. Everyone has their own comfort zone regarding GPU and CPU temps and of course it depends on the card too.

    My comfort zone is 68 to 70C or less during load, but anything below 72C is a pretty safe area. In reality your GPU could probably take considerable more heat than that, but why risk it.

    To keep my GPU temps down I keep my case door cover off and I always air dust every nook and cranny every two weeks.

    I have seen so many people burn out their Video cards because they fail to dust properly and heat from a clogged fan kills it. I mean you gotta take that card out and shoot it good. I myself found a way around that by using an extra long nossel on my air duster so I can get in the fan vents good without removing the card.

    I need to add myself to this thread.

    With my 7800 GS, temperature remains below 62C on full load... and I don't see any artifact whatsoever even if I clock the card to 480/1400 when playing Oblivion, BF2, NWN2 and so on... I mean playing it for hours.

    But if I load up Ati Tool, and set the card to default speed (375/1200), 5 second after the scan for artifact starts.... immediately Ati Tool reports artifacts.
    And artifact keep on appearing on the test even when Ati Tool automaticaly downclock GPU and Memory.

    You tell me...

    i dunno if there is diffrence in agp and pci-e temps. But my oced 7800(617/1422) runs with 55 C in full load(call of juarez with everything on,winamp,other stuff in the backgrtound).

    Your particular verson of 7800gs uses a 7900 type GPU and would therefore be expected to run cooler than any of the trully 7800 chip based cards.

    I am a bit surprised that ATItool shows artifacts with your card at original defaults. However, possibly means that either, your current version of ATItool is faulty, or, the artifacts are influenced by something other than your graphics card?

    Since certain mobo components can also cause artifacts, maybe you should check if the artifacts still show after setting CPU/RAM back to their defaults?

    Welcome to Guru3d !


    The AS500W psu could be your problem?

    Although the manufacturer quotes the +12v line as having a "max" rating of 34A, they also quote a "normal" rating of 25A. Who therefore knows the real 12v rating, especially when you also load up all the other lines of the psu. So, its certainly possible that your "quite a bit of peripherals" is just a bit too much for the psu?

    Of course, maybe it's just that your second SATA drive is faulty? However, very easy to check by simply substituting drives?

    :)

    No Jimmor, same thing happens when CPU is a stock and HT disabled.
    Even setting the clocks down to 2D mode (275/1200) the problem persists.

    What version of ATItool are you using?

    0.25 Beta 16
    Can try different one but I thought that the "stable" release would have been too old for this video card.


    Add:
    Just tried 0.24 which doesnt recognize my video card, but the 3d view works and it does detect artifacts... -_-

    I currently use ATItool 0.25 beta 16 pre8 and find the artifact testing to be very good at detecting too high an overclock ?

    And I normally have the artifact detect slider all the way to the LHS, which means being even more sensitive to artifacts!

    Of course, maybe its just that ATItool has compatibility issues with your particular setup ---> always got to keep in mind that it is a continually developing piece of software ?

    :)

    Aye I thought about that.
    The problem being the lack of other good artifact detecting tools :/
    Unless you tell me otherwise..

    Add: Same thing also with the 0.25 Beta 16 pre8 version.

    Don't currently know of any other tools for detecting artifacts.

    Mind you, since ATItool doesn't actually load a card very much, probably the best, and only real, way is still by visual monitoring of what happens when the card is continually stressed through loop-testing with 3dmark06, games, etc ?

    Yes and that's what I've been doing for 3 hours yesterday. Had my eyes begging for rest...

    Ehehe shame.
    Honest, I'm so tempted to RMA (also to get a G71) but as someone else said, I haven't got enough "faults" to ask for it... :/

    I RMA'd a 7800GS that didn't overclock at all and had artifacts in Ati-tool at stock speeds. I just made something up(don't remember what), BFG gave me no problems. This card is a monster, being G71 helps.

    Thanks for the info and advice. I haven't tried switching the SATA drives yet, maybe tomorrow (too busy downloading and trying out Oblivion mods XD). Are there 2 different versions of the BFG 7800 GS OC? One with a G70 core and another with a G71 core? From pictures on sites I've seen, there is one that has the green and white with the BFG logo on the cooling unit and a greend board, and then there's the one that I have that has a clear cooler unit with a copper heatsink inside it and blue LED's on the fan on a blue board (please, oh please tell me that this is the G71 version, if there is such a thing =P).

    If it's G71 you can check it with rivatuner.
    Just install it and launch , first screen you should see something like :
    256-bit G70 revision A1 (16pp,6vp)
    (mind this is what it says for my 7800GS non G71..:'' )

    Yours is the G71 core, I have the exact same card.
