Windows 7 (64bit), GUIminer and Radeon HD5770 issue

[palinko]

Hi.
I got my first withdraw from slush pool at 2012-05-03 since that datum I'm an active miner, but now I got some problems. There's the error message:

Code:

I got support from chat, we reinstall Catalyst driver and install OpenCL etc. Live For Speed game work with the ATI card and all other programs are run perfectly. Miner was ran normally few days ago with Win8 but I preferr to use Win7 again. Please if anyone have any idea, why don't work mi mining help me out!

guiminer is your problem. use bfgminer or cgminer. there is no "hardware failed verification" error with them

[palinko]

cgminer and bfg miner crash with "not respoding" error so doesn't good for me

[palinko]

up, problem still exist.

up, problem still exist.

What version SDK and drivers did they have you install?

[palinko]

I tried 12.10 driver, but don't work, crash every problem with not respoding error :S
With
13-4_win7_win8_64_dd_ccc_whql
driver we got that error message I pasted in first comment.
SDK is:
AMD-APP-SDK-v2.8-Windows-64

your driver and opencl choice is the problem.

de-install all remnants of amd drivers and opencl with amd's cleanup utility
http://sites.amd.com/us/game/downloads/Pages/catalyst-uninstall-utility.aspx

Install 11.12, select custom install, video driver and hdmi/audio drivers only. dont install the amp app or opencl, it is very slow for 5k and 6k series radeon

Install AMD APP 2.5

voila you can mine

[palinko]

thanks! I don't need to install Open CL because AMD driver installed something new Open CL so I can't rewrite with this old one. I have tried 12.10 driver before, bot got error message, but driver at your link is work perfectly!

You mentioned CGminer and BFG miner before, can you give me advice, wich is best for slush pool and my Radion 5770? Maybe I could setup for autostart and I can mine again with 100% performance
