Do I have to use the latest AMD drivers?

[neuromancerr]

None of the mining clients I've tried (minerGUI, GUIminer, minerd, etc) have worked and I think it might be because I am still using the 11.11 amd drivers. I had a lot of problems with my 5850 and I'm nervous about changing the drivers from something that I know works. Why does it matter what drivers I use?

While I'm making a thread, can I just get a confirmation that I'm doing this right?

Using guiminer-scrypt:

1) I made an account on coinotron.

2) I installed the AMD SDK.

3) I added a miner on coinotron (username: 1, password: 1).

4) I added a port forward for 3333-3336 at 192.168.1.100

5) I ran guiminer and created a new cgminer with these settings:
-host: coinotron.com
-port: 3334
-username: 1
-password: 1
-device: amd athlon x4 640
-extraflags: none
-GPU Defaults: 5850
-Use stratum: yes

Thanks!

you can use any drivers but your missing a step what you need is a stratum proxy go to
file
new miner
new stratum proxy and fill in

host coinotron.com
port 3334

then start then go to your miner tab (what ever you called it and change the info)
host localhost
Port 8332

(this is now connecting through the new stratum proxy to the website)

also the device should be [0-0] cypress
youve got it set to CPU currently
------device: amd athlon x4 640------

do i have to use the stratum proxy? the less complicated the better. i did what you said and it still perpetually says "Connecting" in the summary...

also if i'm using coinotron, does the username i input into guiminer have to be:

username: neuromancer.1     password: coinotron account password

instead of

username: 1    password: 1
