Overclocking ati 4870 1gb

logi-cat · 29 Mar 2010 at 09:01

hi everyone, new to the forum. can anybody tell me what the best tool for overclocking the 4870. at the moment i am using msi afterburner, but for some reason it wont let me go over 790/1100 which is the same as the ati ccc. Suggestions?

Search for how to unlock unofficial overclocking in MSI AB!

Can't remember off hand how to do this. I don't use it, since Rivatuner does it all for me... Software volt modding too

(via someone else's mod)

I can only get my Toxic Vapour X up to around 818 on the core though on default voltage... with a volt increase, around 830-840... Not really worth it, imo :/

thanks sircanealot, i'll try it when i get home. hopefully i can achieve around the same clock speed as you. at the moment i am using a thermalright t-rad2 with a 120mm fan.

Take a look on google for software voltmods. I think I have a pretty bad core imo, so hopefully you'll have some more luck

If you don't have any luck finding a volt mod that works, post here again and I'll try and dig up the one I'm using... There's a few of them, and it always takes me a while to find it and I'm at college right now... ^^;;

You'll probably end up damaging your card and if you don't, you probably won't find any significant improvement anyway.

riva tuner was what i used for the 4850 4870 and 4890 that i had personally i would use that. got my 4890 up to 910/1200 with a good bump of volts cant remember what i managed with the 4870 though they both had been flashed with other bios's though

Look in the MSI install folder for a .cfg file, open it in Notepad, you will see an entry near the bottom for Unoffical Overclocking, currently set to 0, change it to 1, then restart MSI

Why would you damage your card? People have been volt modding for years... As long as you don't go crazy, it's fine.

I just use ati overdrive within the catalyst control centre. 800/1000 seems to do me fine for my usage. Would going beyond this even make much difference in terms of fps in games?
