    HD4870, Accelero Twin Turbo & Temperature ...

    Yes, as mentionned above, it is not a reference layout. I had to use a cutting tool to put heatsinks (those made for VRMs on reference cards) on all required components :) and I also had to use the stock VRM (or in this case MOSFET) heatsink. I removed the thermal band, and applied mx-2 on the...

    HD4870, Accelero Twin Turbo & Temperature ...

    First of all, thank you all for your answers. As suggested, I went for a reinstallation of the main heatsink. 1st try : complete cleaning (asaka cleaning x 2), reapplying AC-MX2 evenly, resetting the heatsink. No dice, GPU-Z temps even raised to almost 70°C idle. 2nd try : instead of...

    Thank you very much, I thought these would be the places to put them on, so I did it yesterday. I had to use my dremmel (cutting tool) to shape the heatsinks for the upper-right part on the picture. As I wasn't sure, I also put one heatsink on the bottom-right ones :rolleyes: My Accelero Twin...

    I don't know about doing it with RivaTuner, but you can use Radeon BIOS Editor to increase overdrive limits (see tutorial).

    ATI 48x0 OCing thread/advice

    Hey there, I have a Sapphire HD4870 512M (black latest model), and it goes from stock 750/900 to 780/950 with stock cooler (VRM are far too hot though). I'm using CCC and RBE (mainly modified my stock BIOS fan activation curb, didn't change voltages yet). I'm waiting for an arctic cooling...
