##
## General
##
Q) How do I use oclHashcat / How do I get maximum performance?
A) These things are nicely documented. Check out the docs/ folder.
Q) Will the source be published?
A) No.
Q) Will there be a Mac version?
A) No.
Q) I want an additional algorithm! How shall I request it?
A) Create a topic, submit some C code for that algo and some hash:plaintext pairs.
Q) My wordlist is to big, oclHashcat can not load it.
A) This is an old oclHashcat issue < v0.20. Just upgrade to the latest oclHashcat version.
Q) I have a 2 GPU gfx card, but only 1 GPU is used!
A) Disable Crossfire/SLI.
##
## Windows specific
##
Q) I get this Error "OpenCL.dll is missing"
A) You are using old driver. Make sure you have at least:
* ForceWare 256.x for NV users.
* Catalyst 10.9 and ATI Stream SDK v2.2 for ATI users.
Q) I get this Error "ERROR: clGetPlatformIDs() -1001"
A) If you switched from NVidia to ATI you need to double install the Catalyst driver due to some Bug in the driver. So you need to install Catalyst and SDK, then uninstall Catalyst and then reinstall Catalyst.
Q) I want to squeeze all the juice my gfx card has, but Vista/W7 crashes/initiates WDDM timeout thing. How can I overcome it?
A) Create a "patch.reg" file, open it with notepad and paste the following code:
Code:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers]
"TdrLevel"=dword:00000000Then run it, press OK, and those issues will disappear.

## Linux specific
##
Q) I get this Error: "Error in clGetPlatformIDs()"
A) You are using old driver. Make sure you have at least :
* ForceWare 256.x for NV users.
* Catalyst 10.9 and ATI Stream SDK v2.2 for ATI users.
Q) I get this Error: libOpenCL.so: no version information available
A) This is an Error in NVidias OpenCL runtime on Linux. AFAIK it have no effect on oclHashcat. Just ignore it.
Q) I get this Error: ./oclHashcat64.bin: 2: Syntax error: "(" unexpected
A) You tried to run $ sh ./oclHashcat64.bin which is wrong. Do not use "sh". Example: $ ./oclHashcat64.bin
