I assembled a new computer recently using Gigabyte's 8800 GT from newegg. I've been having random crash issues both while playing games and when just surfing the net or using windows explorer. After several attempts to fix it to no avail I swapped the card with my dad's Radeon 2900 (I think that's the right number). Anyway my computer worked fine and his had crashing issues so we knew it was either the card itself or the drivers.
I just remembered today that my 8800 GT came factory overclocked with a core clock speed of 700mhz. So we downloaded the Nvidia nTune program to scale back the clock speed. This is where the weird speed come in. nTune lists the factory settings at 450mhz for the core bus speed and 700mhz for the memory bus speed. What gives? I thought the core was supposed to be 700 and according to various sites (but not listed on Newegg's, Nvidia's, or Gigabyte's websites) the memory speed is supposed to be 1400+. Anyway, we scaled back the memory speed to 650 and ran the stress test. It passed now whereas it had failed earlier. I haven't yet tested the card's lower speed under gaming conditions, but I have a good feeling that my crashing problems lie with the clock speeds of the card.
So, does anyone know why nTune lists the speeds it does, even though that conflicts with specifications from online? What might good clock speeds be? Oh, and I don't think that the crashing problems stem from overheating or the power supply. The card is always room temperature or only slightly warm even after gaming. I have a 530W modular power supply and my dad has a 600W one. Not to mention I can run Crysis for an hour or two if I'm lucky before crashing.
