Configuration for speed up ocl ? - Mem5 - 05-13-2012
Hi,
I tested oclhashcat on my new HD 5870 (1600cores@850Mhz)
I read a speed estimation of 5018M for single MD5.
But I only have :
Quote:Speed........: 1712.6M c/s Real, 1399.0M c/s GPU
1) How can I speed up ? Which values for "--gpu-loops" and "-n" ?
2) Do you advice to overclock it ?
Thank you.

for full speed on single md5 you have to use -lite!
RE: Configuration for speed up ocl ? - Mem5 - 05-13-2012
Yes but if I have several hashes, so I use *-plus.

to get full speed you need to use -lite. only single hashes can be unwind that much.
RE: Configuration for speed up ocl ? - Mem5 - 05-13-2012
Ok.
And for "--gpu-loops" and "-n", what can you advice me ?

@Mem5:: I would suggest you to increase "-n" when brute-forcing, decrease when dicting (Dictionary attack) xD.
And lower "--gpu-loops" when attacking slow-as-hell algorithms (phpBB3, Wordpress.. etc), also lower it when having huge lists of any salted algo.

For oclHashcat-plus 0.081, u need AMD users require Catalyst 12.4 or later otherwise you'll get incorrect hash matches. For oclHashcat-lite u need AMD users require Catalyst 12.2.
