hello, my first post here and I need please your help. asus 1155 mobo, G840 , vtx3d 7850 2gb x-edition , win 8 I bought this card used and I have problem (at 1900x1200 resolution only) whenever I try to see videos from internet (i.e youtube) then the internet speed goes low and after 10-30 sec the screen goes in" light blue" with running thin horizontal white lines ( seems to be analysis problem) my pc was bricked. Playback videos and hd videos from dvd or hdd are without problem. I have try load some of the new ATI drivers and the new flash player version. The reset it was the only way for exit. Same problem when I try this card at another pc. Using catalyst center , I try to minimize the core & mem clock , nothing changed. The temp of the card seems to be low ( about 40oC , the VDDC voltage is 0.9v , except during ********* videos which is 1.210v). Is thia correct ? I don’t know if the previous owner has made any bios update or he has oveclocked the card. I don't know what I could check and what can I do. How can I find if the loaded bios is the correct one for this card ? Please suggest me what to do. thanks
I don't know if this will help but try enabling "GPU Scaling" in CCC. It's located under "My Digital Flat Panel" -> "Properties (Digital Flat Panel)."
hi, thanks for your attention. The psu is the corsair Ax650w is 5 year old. Seems to be not psu problem because I have try this card to another pc (1st pc win8, 2nd pc win7) with exactly the same problem. Also I observe ( I use a graphical download internet meter ) that just the stream video starts , the download internet data are not continues but makes like "square pulses" i.e download at high speed for 5 sec , no any download for 20 sec and continious like this. Seems to be as disturbed while in *********. Also , in that explorer window ( firefox or ie ) nothing works any more either if I open new tab ( the click don't opens nothing). I need to close the window and to open a new , and all story starts from the begining. some questions now If a card works as overclocked , these settings are saved inside the card or at the pc ? i.e this card in another pc will work with the official settings or with the previous overclocked settings from the old pc setting ? Any idea to find the official bios ? How may check ( which software ) the setting for my card and also the profiles if has any ? Is possible a wrong profile to makes these problems in ********* ? thanks for your help
When a GPU is overclocked it's saved on the PC. ...I don't know of any GPU's that have internal OC'ing. So when the card is installed into another PC it is just a regular 7850 again. To be honest your situations sounds really odd... And considering you installed the 7850 in a friends PC and it ran fine, might be good news for you! Make sure that you're running the latest stable Catalyst Control Center drivers. If you already are using the latest stable drivers, then I recommend you try borrowing a friend's AMD GPU and install his card into your PC, and see if you still have problems. You probably just got a faulty GPU, or are [unlikely] using outdated drivers. Assuming you've owned this PC from the start, I doubt your GPU is overclocked. So I don't think there would be any profiles in CCC that are OC'ing your card. Nevertheless, take a look in CCC anyway, and make sure the "Overdrive" option is unchecked.
