ATi 4870

post #1 of 8
Thread Starter 
Does anyone know if I can max out the core and memory clocks in CCC (790/1100) safely? When I'm using standard clocks the temp idles at around 45C and at load 60-70C. I'm using stock gpu cooler but there are two extra fans in my case. Also if it is safe to do this what fan speed should I set?

Thanks

Oh yeah, will this shorten the life of my card? Don't want it to die on me...

well... just watch out for the temp and make sure it's stable nothing could possibly go wrong

Definitely, CCC does not give these much OC room. I used MSI afterburner on mine. Got it to 840/1140 stable.

I never ran it 24/7 like that though, no reason to while surfin the web or whatever. Just used it for benching and a couple games.

It all depends on if it is stable or not. You must test it for artifacting by using GPUTool or similar app. And definitely keep an eye on temps, especially for the RAM which can be monitored using GPUZ. I personally would not use CCC though to OC as I would MSI Afterburner. Your fan speed will be determined by your temps so you must adjust it accordingly to compensate for the extra heat.

Wait are you saying I should disable the overclocks every time I quit my game? Or is there a way to set it up automaticly?

Well, in MSI Afterburner you can create up to 5 profiles I believe it is. You can save 5 different OC settings. Set them to whatever you like for whatever task and choose accordingly. I guess you can leave your card at a comfy OC 24/7, but I dont see why. But I'm big on power saving and cool temps. I dont use a 24/7 OC that I cant use Cool N Quiet on for my CPU, and do not leave my video card OC'ed 24/7.

Thats why I run my CPU at 4.0ghz, cuz if I run at 4.1 or 4.2 with a higher multiplier, CnQ doesnt kick in. So I have higher OC's saved in Bios for when I need them.

Ok so I'm using gpu tool and occaisionally some pixels go yellow?? What does that mean?

EDIT: Nevermind, it was artifacting I think, I turned down the speed on my memory and it was fine.
