4850 running really hot and im trying to overclock it.

You click the key at the near upper right side of the windows to unlock it. Then you can select it to find the highest safe overclock.

4850' do run hot, very hot, try putting a case fan near it.

Your clocks are kind of low...

My stock clocks are gpu 625MHz and memory 993MHz. Enable manual fan speed control, crank it up until it's idling in the low/mid 40s, then go from there.

I have done the unclocking thing. However everytime i change the clocks and i press apply, the currrent values stay the same.

Also is it okay for the card to run that hot?

Use riva tuner so you can put your fan to 100% and its a better OC app, or you can flash the BIOS so it is always at that speed. 60c seems kinda hot, is that your idle temp?

I dont know, Im not to familiar with overdrive. Did you check your OC with GPUZ? Seriously though you will have better luck with Riva 224 MSI 2009

The 4850 was designed to run around 95C load so your temps are fine. The 500mhz you're looking at is the cards 2d clock, when it goes to 3d mode it'll be at 625mhz core

Maybe, but the cooler you keep it the better it will maintain stable clocks.

If you have better air circulating, you'd see temps, with 50% fan, around 40-45c on idle. That's what I used to get with my 4850.

I use Riva tuner for Overclocking my 4850. My 4850 is the MSI one with the fan that is stuck at 100%. With my clocks at 730/1050(24/7) I usually don't go over 60c even running furmark extreme burning for an hour +. But my case is open and layed on its side. I would turn that fan up and Oc the hell out of it. With my card 730 is about the max. I have pushed it to 750/1050 and had a tiny bit of artifacting in furmark. Depends on the card i guess on how far you can push it before issues. Pushing the memory over 1050 causes issues though like 5 consecutive VPU recoveries then a bsod.....
