Overclocking Radeon 4850

[resident56]

I have the fan speed set as normal, are these speeds cooking my GPU? Ive heard alot of rumors about fan speeds on these cards not being as high as they need to. 87 was the max temp I got through running Crysis's GPU benchmark.

I have seen alot of people going to 700mhz on the stock cooler, temps don't matter unless you are having an issues specifically related to temps such as random shut downs- if it plays your games fine then there is no cause for worry.

Personally with my 8800GT, I got twitchy at 90C and usually had a failsafe fan speed to dump air onto the heatsink at 92C to stop it going any further.

With my HD4870... I am being very finicky. 80C is really starting to get my goat at idle and even then, the fan is auto-throttling higher to my annoyance.

I guess I must be swayed by all of this "OMG my temps are too high but they are only 80C!!!!"

Try FurMark if you want to see how high your GPU temps will go under its stress/stability test,I got up to 92c on my 4870,no game I own will ever get as high as that.

Are you stalking my posts? 😛

Did you run the FurMark test without BIOS/profile mod? ie. Fanspeed at normal (unmodded, automatic 26% base) and stock speeds?

Also, bookmarked this for viewing when I get home from work.

I manually set the fan speed using a CCC profile, and at 40% I never go over 70 at load. I may push this card more but not until some new catalysts come out.

Hehe no!!!!..just being helpful,as to your questions my 4870 is unmodded and no fan hack(so using default settings etc..).

Lol, guys don't complain about temps, they arn't a problem. On furmark, under full load, my vanilla 6800 runs at 100C +. I've seen it up to 105C one time. No artifacts though, and it still works, so i don't think that temperature is really a problem unless it actually frys your chip.

Agreed. I ran it at 16x10, 4xAA, and my 4850 was at about 100~105. I can't remember what my fan speed was though.

20 minutes 1920x1080 with x8 MSAA to really set it as high as I can go (TV's limit is 1080i) and let loose. Temps wavered between 88C and 89C. Cooler was dumping out a ton of heat... as was my exhaust and PSU fans.

Toasty!
