First of all, hi to everyone around here. I'm posting this here to see if someone can help me (long story). Last October, I bought a Powercolor X800 Pro card (upgrading from a nVidia 5600 which never gave me any problems, though it was just a slow card ). However, I had some random freezes when playing 3d games, or when running 3D Mark. Eventually, I came to the conclusion that, everytime my card reached 53/54.º Celsius, the image just freezed or completely vanished from my PC (VPU recover on or off, it didn't matter). First, I thought it was the PSU, bought a LC Super Silent V2 but had no luck. Returned the card, but the guys at the shop showed me later that the card had no problems reaching 60+ Degrees at their own computer. After scrathing my head a lot, I finally found that the Video Ram Cacheable on the BIOS was the source (or so I thought) of the problem. After disabling it, voilà, no more freezes However, in the last fortnight or so, I started having freezes when playing some games. I decided to run some programs to check what the hell was the problem, and I was shocked, the mother..... was freezing all over again, this time when reaching 52.ºCelsius I've uninstalled (with driver cleaner) and installed newer/older drivers, changed back and forth the settings on the BIOS for the Video Ram Cacheable (and even Fast Writes, the AGP Bus Speed and the AGP Aperture size), but to no avail. Am I missing something? Is the card fried (never tried any OC and never tried any stupid bios flashing move)? As far as I can tell, the stupid b...... is just telling my videocard to shut down when reaching that temperature, but hey, 52.ºC is way too low as dangerous temperature BTW, here are my PC specs: AMD Athlon XP2800+ Abit Nf7 Powercolor X800 Pro (no enhancement, no OC, no nothing).
