BitCoin Mining with an ATI Radeon card in Windows 7 (32/64 bit)

foreverrising, April 15, 2011

After having trouble with installing the correct drivers in Ubuntu 10.10 64-Bit, I rebooted into Windows 7. The process is extremely easy on a Windows machine.

First you’ll want to install your ATI Radeon card, And when Windows tries to install drivers for you, cancel it. You want to install the Catalyst Software Suite, and install drivers that way (If you’re using 32 bit you’ll have to search for the correct version). The Catalyst Control Center application also lets you overclock the card as well.

Next, you will want to make sure your BitCoin client is installed. It does not need to be running while mining BitCoins. If you plan to use your BitCoin client as a server, ensure you have created your configuration file at C:Users[USERNAME]AppDataRoamingBitcoinbitcoin.conf with the following:

rpcuser=[choose a username]
rpcpassword=[choose a password]

Then you’ll want to download a miner. I have been using poclbm-mod (03.24.2011), on If you chose that, then you’ll need to sign-up for an account.

To make it easy, there is a batch file included in the poclbm-mod file, in the binaries-win32 directory. Don’t use the GUI version, it’s less efficient. Make sure that you edit it to include your username and password to connect.

Example for Radeon Card:

poclbm-mod.exe -d 0 -v -w 128 -f 60 -user=USERNAME –pass=PASSWORD

If you happen to get a vector error, try changing the device flag from -d 0 to -d 1

You can also adjust the -f flag, higher leads to better frame rates for the desktop, less increases performance a bit for mining.


I also got my Radeon 5770 installed and mining in Ubuntu 10.10 64 bit last night, I’ll be doing a write-up of that tomorrow.

I accept donations @ 1HXrbVT3WRqk6rHTPKKJ9ppoFbsYjmjTqX if this worked for you. If it didn’t, feel free to send me a comment.

Let us know what card you have and what hashrate you get it to!

    Import Error: DLL load failed: the specified module could not be found

    my gpu device isnt opencl compatible is that why im getting this error?

    1. I believe ATI cards that are 4000 series and above are compatible. You would be able to use a CPU miner, but I would look for a more modern card.

    Seems to work for me. I have a ATI HD5860.

  3. Works great on my on my HD4350 added about 500khash/s

      Hi, dude i have an ATI HD 4550 and don’t know how to configure it to get a good hashing speed like yours. Could you help me?

      Windows XP 32-bit, Catalist 11.7, AMD SDK 2.5, Gigabyte 6950 1Gb (core clock 870@915) — 350 Mhash/s

      1. Nice. I only get 302 with my 6870, and 213 with my 5770. They would be better if I had 2.1 slots instead of 2.0.

      2. Lower your memory clock to 300MHz.

    Does anyone if crossfire has any effect on mining??
    And does radeon hd4290 support mining (opencl)??

    1. You will want to disable crossfire. 4XXX series of cards should work. Please let me know what hash rate you get.

  6. anon says:

    I’m interested in trying this, however I only have a HD 4870 X2 dual GPU card. Think it’ll work properly now when it’s technically Crossfire ?

    1. It should work. Just to make sure I would use the command:

      aticonfig –crossfire=off

        Thank you for the reply.

        Using your method the worker strangely would not start.
        With -F60, as I usually use, it works splended. About 120Mh/s total.

        1. I’m sorry, I didn’t notice you responded to the Windows post (aticonfig is a linux command). Try using -f0, and check out the phoenix miner post. You will get better results, I just haven’t revised all my posts yet.
