Verification failed, check hardware!

[rafaeldotjs]

poclbm doesn't work with the new AMD drivers. I upgraded to 13.4 and now everytime I try to mine with poclbm I get "Verification failed, check hardware!".

In fact, looks like it stopped working with all the other miners as well.

Hi,

I got the same problem with 13.4 and many phatk kernel based miner.

It s look like that come from some modifications made by amd in the opencl drivers.

The problem look like located line 30 of the phatk kernel :

39 #ifdef BFI_INT
40 #define Ch(x, y, z) amd_bytealign(x, y, z)
41 #else
42 #define Ch(x, y, z) bitselect(z, y, x)
43 #endif

remove that code and replace it by :

Code:

#define Ch(x, y, z) bitselect(z, y, x)

The amd_bytealign seems have changes in recent driver but can't found documentations ... That s works for my 5770 with driver version 13.4-2

A good things would probably to try to detect the driver version and set or not the BFI_INT

Regards,

This is still happening.

I have the same problem as well. I have a two ATI 6870s and i get this error all the time and can't mine.

I tried the above solution. If someone could help me out I would probably blow them. Thanks

I "solved" it by replacing amdocl64.dll with a previous version.

Uploaded it to MEGA, but you can still find it with google: https://mega.co.nz/#!UsF31JAL!H5U_gAnHRagfcsgBSry7kxQkp0ROAM4OOQMJPA7Vmow

Is it possible to just live swap these .dll files or do i need to restart the PC every time?

I'm sorry but still no go with that link. I don't get it. No matter what i do i get the error.

I have: two ATI 6870s windows 7 CCC 13.4 and what ever hte lated AMD APP SDK is.

I honestly don't know what to install other than those. I tried 11.11 ccc like some guide told me to and it just broke everything.

If someone could email me at timlinton(the number zero) at gmail ]dot[ com and give me some kind of life help i would be eternally grateful. I just want this running... why is it so hard?

Should I maybe try an older verson of the amd app sdk? considering an older CCC was a complete failure.

My error log is just a mass repeat of this::::

Traceback (most recent call last): File "guiminer.py", line 860, in toggle_mining File "guiminer.py", line 1001, in start_mining File "subprocess.pyo", line 679, in init File "subprocess.pyo", line 896, in _execute_child WindowsError: [Error 2] The system cannot find the file specified

I think I fixed it. I went and did what you said before and then used MultiMiner and ran it as bfgminer settings. Works great.

The solution from @khertan worked for me. You have to edit the file 'phatk.cl'.

I don't know if the performance is sacrificed, because is my first time mining. Thank you @khertan.

@khertan - You are the best - I have been banging my head against the wall trying to figure the issue with my HD 5800 series for 2 days. Follow the instructions provided to edit the phatk file inside the guiminer folder and let your frustrations end. @esevece the before and after readings indicate it did not sacrifice any performance. Thanks again.

@sheehan86 that's great.
