9800 game freezes: temperature related?
I've got a 9800NP flashed with a pro bios. In NR2003, the game video
freezes and a few moments later, the system locks up. At stock 9800p speeds, the freeze happens after a few minutes of running in 3d. I turned the clocks back down to np speeds with powerstrip, and the game ran for a good 10 or 15 minutes before eventually locking. I haven't had time since to try to reproduce this behavior. I am working along the path for now that heat buildup is the culprit. After exiting the game, the hw monitor reports that the CPU and system temps are within a normal range, so I am wondering if the GPU or memory on the 9800 is getting too hot. I have some extra probes that I could use to measure temps. My hypothesis is that temperature will rise continuously until it reaches the critical point at which the game will lock. If I then reduce clock speeds, tempertatures will rise at a slower rate, but will still eventually reach the critical point and the game will lock. If temperatures remain constant prior to the game locking, or if the game locks at varying temperatures... I think this would rule out temperature as an issue. What is a "normal" operating temp for the GPU and/or memory? I dont get any corruption, etc. before it freezes. It looks outstanding, then it just locks up. Your feedback welcomed, Gerald |

Your feedback welcomed, Gerald Gerald, as a simple preliminary test, just try removing the side cover off your computer case and allow a regular house fan to blow in......this should relieve any heat build up and give you an idea of what needs to be done. If it cures the lockup, you need greater cooling, if not, then you're back to the tortuous troubleshooting path. Taking the cover off is free, and fast. Ed |

This of course crossed my mind. But my PC is in a ventilated enclosure inside a crawlspace (my solution for a silent and less visible home theater PC). Moving it from there into a place where I could follow your suggestion is actually more of a PITA than simply placing some probes on/near the ATI card. What I don't know is what the expected temps SHOULD be for the GPU and/or memory. If I still get failures at "normal" temps then heat probably isn't the direct cause, even if it fails at the same point every time. Gerald |
