Allright so I thought to make this thread for the reason that MANY MANY people are having hard times to get their ATI product to work. Nobody from ATI seems to care, or for the matter of fact I even think that they themselves dont know what problems their cards are having and ALL BECAUSE OF ATI DRIVERS! I myself bought a HD5970 wich worked fine with my old windows for a few hours, then took out my other harddrive to install a benchmarking Windows on it. When Windows was installed all was perfect, when I installed the drivers, immidietly I noticed ARTIFACTS on the screen, I mean I havent seen artifacts on new cards from the 9800 series that ATI had. Thats a long time! I just could not figure out what was the friggin problem, I was astonished when I typed into google "5970 Artifacts".. tons of people having this problem with NEW cards, even some sending them to RMA to get a new card in return wich also artifacted, now that did not make any sense at all. Finally after searching for hours on end through many forums I stumbled upon a FIX! The problem that ATI 5xxx series hanged, artifacted, gsod etc was that the 2D Clocks of the cards went too low! 156MHz core and 300MHz memory. ATI seemed to fix this with a driver update but did not touch the memory clocks! I then went to DOS and flashed my new card with higher 2D clocks for the GPU, 300MHz. When I got to windows, all was fine but when I opened up program like MSI Afterburner, heeey ARTIFACTS! I then researched some more and got to the conclusion that the MEMORY needs to be raised as well! Some raised it to 1000MHz but all that is needed is 400MHz 2D! So, again opened up Radeon BIOS Editor, changed the clocks and reboot. And it works! No artifacts anymore ever! Flash program: http://www.techpowerup.com/rbe/ When in DOS type: atiflash -p -f 0 masterbios.bin atiflash -p -f 1 slavebios.bin The card has a master and a slave bios! So dont flash a master bios on the slave card or vice versa! I did notice that my original BIOS that had manual fan control option in it still artifacted though!!! I had to download a older BIOS for the card that didnt have the manual fan control in it and guess what, the card works as it should now! BUT!! hahaa, there is still a but! ATI was so kind that it thought, HEY lets implemend ULPS in our drivers! This would cause all info programs like CPU-Z, GPU-Z, Everest.. etc whatever the program was that read videocard information to HANG the whole PC! BUT ITS WORTH IT It is so good that we dont care that some tiny program like CPU-Z or GPU-Z hangs, nobody uses them right?!?! They are for overclockers anyway and tahts voiding the warranty so lets do this EPIC change!! What ULPS is, it is a new feature in the Catalyst Drivers, its a power-saving feature and it completley shuts down any non-primary GPU-s in Crossfire mode! It works when the card is not in 3D mode, that means in windows. So when the non-primary GPU is shut down and you open a program like the new CPU-Z that has GRAPHICS info in it, it starts to want to read the info from the non-primary card also, what that does is INSTANT HANG of the whole PC! Only way to resume work is by resetting your PC! This was the whole text that I found from the Everest forum: So, what to say? Well if this is not fixed before the GTX480 is out, I will sell this card and NEVER EVER am I buying ATI again, NEVER! I dont care if its 50% faster, the driver fuzz behind ATI is more than horrible, its like.... how do I say it... I FEEL LIKE I BOUGHT A TOYOTA!
