All ATI folders. Please update to client 6.23 andif you are there look at your log file to see if you are on core 1.22 it can be found below.

[05:26:48] Folding@Home GPU Core - Beta
[05:26:48]
Version 1.22 (Mon Dec 8 12:57:56 PST 2008)
[05:26:48]
[05:26:48] Compiler : Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 14.00.50727.762 for 80x86
[05:26:48] Build host: amoeba
[05:26:48] Board Type: AMD
If so please update your system with the following to allow full use of your GPU, and less CPU useage and bandwidth used by F@H
For Vista
Right click "Computer" click "Properties" click "Advanced System Settings" and now clikc "Enviroment Variables"
Below "System Variables" there is a option for New, click it and add the following setting untill you reach the best mix of GPU useage.
Variable Name
FLUSH_INTERVAL
Variable Value
card 4870/4850
256 up to 512
card 3870/3850
128 up to 256
When done open a command window and type
echo %FLUSH_INTERVAL%
Then check your CPU, and GPU use to what it was previously. Tweak up or down according to your wants for performance and or system response.
This only effects ATI users, and only those with the new core, and only those that are seeing less then 80-90% GPU useage and a increase of CPU use.

In your environment, you can set FLUSH_INTERVAL to a value between 2 and 1024. This flag sets the maximum command packet size sent to the GPU. The default in the core is 16 which seems to solve the lag problems for most people, but at some added CPU overhead. People with higher-end boards can manually adjust this value until we deprecate this flag in later cores. The higher the value this flag is, the less driver overhead and lower CPU usage you will have, but there is still CPU optimization work going into later CAL releases and F@H cores. Setting this value to high will cause UI lag and potentially VPU recover and is designed more for advanced users. The lower the value, the smaller the command packet which translates into other graphics apps being able to play nice.
From the Folding at home forums, for ATI cards using the new core.
You can use the GPU-z tool available from this site to check your GPU use and also temps if you are worried.
----------------------------------------------------------------------
I used this method and was pushed from 50-60% up to 90% GPU use, as well as going from 15% CPU use on one core to 2-4% use. This changes the packet size sent to the GPU.
,my gift coming on December 29, can't wait..
and also ati-3850 around 10,000 ppd I can give
(ship to canada?) and don't worry i use it 24/7 for folding thanks
