i have ati 4850, i asked before in this forum about my vga high temperature in idle mode and sometimes it freezes in some heavy games and my screen goes blank and i should restart my system , i want to know a weak power supply can make a vga to make more heat ? if yes why is that ?
i have asus p5q, cpu q6600, ram 2x2gb 1066, vga ati 4850 512mb, 2x500gb sataII (raid), one dvd writer, one 56k modem, one adsl modem, one 1tb external hard drive, one external fan, at least 5 usb devices
Ur card is running at high temp....that doesnt mean u have issues with the power....get a 120mm and find a spot on ur chassis 2 place it.....make sure everything is ventilated enough.....ur GPU fan may be dust laden.....clean it.....
idle temperature is about 80 !
in some games after 10-15 minutes the game crashes and screen goes blank and monitor shows out of optimal resolution message, and the only way is to restart !
I have a 120mm fan in my chassis , also cleaned my vga fan, but not a chance !
Get Gpu-z and record the temperature after booting....I mean after shutting down the system for 2 hours or so.....see whether the temp spikes are happening suddenly or over a period of time.....jus change the OS and check the card....
yes it will goes up, but as i said before after some time it crashes !
i manually set the fan speed to higher values , it will cool down the gpu about 25 degrees, but it just save some more time and it crashes after a longer time
the fan does dyanmically change the speed according 2 the load....u can get riva tuner and set the fan speed to 100% and see if it works....u also may try by downclocking the GPU....see if it helps.....
You could also get some new thermal paste. Take off the cooler, clean it with alcoholic and a swap, then reapply paste. Sometimes the factory paste isn't applied correctly. I've fixed a card by doing this already. If its a problem that just started happening, the paste maybe oozing out or turning solid.
