Title: Ultimate Guiminer OpenCL Flagtest [AMD HD6950 1GB]
Post by: Salazarian on June 27, 2012, 05:11:13 PM
Hi folks,

when I had time I started to test flags for the xfx hd6950 1gb graffics card!
I am still not finished but as I only got this card, I wanted to make a VERY NICE Graph and give you details what FLAGS you REALLY should use!
It was very time abusing but hey, now you have an evidence which flags you should use ;)

For FULL transparency I provide you the data itself to check or make own graphs etc.:

Guiminer   24.08.2011
Open CL   
Catalyst 2.1   
Powetune: 0%   
Standard Shader
Windows 7 32 Bit



Now, my result was:

The best flags are [-f0 -v -w64] or [-f0 -v -w128] [depends on your GPU Core ;)
The values are for a standard 6950!

My highest speed was 800|300 0,9 V at 322 mhash/s with -w64 or -w128



Values for an unlocked 6950 are not shown but you might guess that -w64 or -w128 are still the best to use ;)


Donations are always desirable IF could help you =)
