fresh win7 install - new system (havent followed overclocking in years).

have this card:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814131140

confirmed with GPU-Z that core is running 770mhz and memory at 900.

what app do i use to overclock? is riva-tuner still the app of choice?

what should i push for on stock HSF - 800mhz core and what about memory? what are the standard hittable speeds on a stock hsf 4870?

thanks,
 
I just used the built-in OC utility. However, my card seems to always be unstable over stock settings so I just leave it be.
 
I have that same card, except it's the 1GB version, and it's very bad for overclocking.
I can't even OC the memories without getting crazy artifacting.

I use CCC to OC core and memory and also for manual fan contol. It works well. My card is a poor overclocker as well.

If you think your card is a poor overclocker... I can't even get past 915MHz on the RAM LOL
 
RAM overclocking is pretty much useless with 4870s. Running mine at 1000MHz hasn't made any perceptible difference to anything, so if you can't overclock yours too much, don't worry about it. As for the core, you should be able to easily hit 790MHz, which is the highest you can go in CCC.
 
My xfx can get to 800/1100 according to rivatuner and gpu-z, so I'm a bit surprised to read you guys saying that o erclocking memory has been an issue. It us a brand new one though.

I'm amazed that a $140 card can max out crysis wh at 1680 w no aa. My i7 is barely breaking a sweat in game.
 
4870 can do 850/1100 through with adding a bit of voltage, but on stock, NO!! it does not really oc a crap :S
