does somebody know about the error "Verification failed, check hardware"

[tamehuang]

sorry, i'm a chinese. don't make fun of me because my english is very poor.
i ask my question in some chinese community but noboy can give me a solution. so i have to set this problem to here.

my computer: win 7 / 64bit / ATI display card
my software: GUIMiner v2012-12-03
all drivers is newest and SDK 2.8 is installed.

when i'm mining, it always show me the 'Verification failed, check hardware' error like this:

i don't know what it means. i run GPU-Z to check my display card. the OPENCL is ok.
could somebody give me a solution here? no matter if you fix it or not, thank you all the same.

by the way, if you need more infomation about it, reply my topic to tell me please.

thanks

Hello.

Lets get more info first.  What graphics card are you trying to use? And are you overclocking it at all with another program, if so what are your settings?

thanks for your answer. my card is 'ATI Radeon HD 6570'. I'm not overclocking it.

Are you using any specific arguments with cgminer? Vectors, auto fan, etc?

[tamehuang]

my tool is GUIMiner but not cgminer. it seems like all are correct. because it runs fine on my laptop(nvidia card).

look at the picture from my laptop. they are the same config. the only difference: laptop is GF 310M. PC is ATI HD 6570(GUIMiner display it as [0-0]Turks).



Puzzling....

My apologies on CGminer, I confused myself.  The only thing I can think of is that the 2.8 SDK isnt playing well with that card.  Try uninstalling that and instead go with 2.4 SDK.
