Here is a full modding guide for the Ati HD4870X2 gfx card.
you need a screwdriver and a sharp knife and a good solder iron and some small wires
And 2x50 Ohm and 1x50K Ohm Multiturn Vrs
And a lot of paticence.
The first thing we have to start with is to dismantle the card.
The card it self.
The back of the card.
And now to unscrew all the screws.
And then we can take the back cover of the card, be carefull not to harm the mempads
as you are gonna use them again.
The rest can be seen here...

I have done 5 cards this way now and it works great the cooler can be run at higher
fanspeed with the same noise and the card is about 20-25c lower at load temps.
And the cores can be run at 1.40-1.425v without a problem on stock cooler.
I have got my card up to 950 on both cores and the mem on 1090 stable and
1125 not stable but i have water on the card.
Note dont go any higher than 1.75-1.80v on the mems becaus they will articfact alot.
Happy modding from www.Octeamdenmark.com And me(riska)
