Updated phatk.cl file for GuiMiner %2 Increase + Stable + No Stales + It Rocks Try it Grin

No more Jumping from 401 414 409 407 like that ..... Shocked

%2 overall gains for my 32 Graphic cards - 6870, 6950, 6970, use-n the -v -w128 -f0 + the phatk.cl with Guiminer Roll Eyes

I thought I'd try this phatk.cl file, so I'll let you know how I get on.

However I am having speed issues with my 6970. Just installed it today, trying it out.

I have it overclocked with Sapphire TriXX to

Core 1000. (stock 880)
Mem 5488 (Mem slightly underclocked (I gather thats a good thing - stock 5500).
Voltage 1293.

(I gather that voltage is controlled by CCC anyway, so you can put it in any setting on TriXX. This setting is near/at the end of the slider in TriXX but is also what someone else reported running at.)

TriXX reports the Driver Version as Catalyst 11.8. These are the sorts of stats I've seen reported on this forum. Not even sure why Catalyst would be a driver?

I'm using Win7 / 64

I was looking at the flags you're using: -k phatk -v -w128 -f0

I notice you're using Radeon cards. I thought those flags were used with the CUDA miner in GUIminer (NV cards)?

I tried using those flags on my GUIminer / Phoenix miner, got error. Tried using them on GUIminer / OpenCL, got error.

The only other miner worth using in GUIminer is the CUDA (NV cards). No use with my 6970.

I've also been playing around with GUIminer: OpenCL vs Phoenix. Different flags etc. The flags I've settled on for now (using phoenix) are:
-k phatk VECTORS BFI_INT FASTLOOP=false AGGRESSION=11.

I've even tried the "real" Phoenix miner (not part of GUIminer).... Got less speed in the "standalone" Phoenix than within GUI.

The overclocking has made the most difference in hashing speed. I'm now running at about 363-365 Mh. However much lower than the 400+ reported by others.

Anyway, I've followed the ideas I've seen on this forum for speeding up a 6970. I see I'm not the only one struggling with slower speeds on this card!
400 MHash seems like a long way to go based on my experience so far!

I possibly need to use another miner, or maybe the faster miners on 6970 are using Linux?

PS: my GUIminer version is v2011-07-01.
