5770 210 ? 910 MHz 1250 MHz Reaper V13 Beta 4 x644 256Work, Agg 17, 4 GPU Threads, Win7 x64

Give 4 GPU threads, and agg 17 a try.
Over aggression can slow it down.
I tried 19 on my 7970 and I got 180,
but when I went down to 13 or so it went up to 560.
Try a lower aggression.
First try 17, then 14.
If its in the second slot, and its a dedicated card,
like my 6870 is and gets 300 KH, then aggression 19 should work.
If its not dedicated, and it does the drawing of your desktop, etc.
Lower is better. My second card doesn't do any drawing,
its a different card, I have a 7970 and 6870 in my computer.
But you have two 5770, and with crossfire?
So lower aggression is better.
Unless you unhook the crossfire,
and dedicate one card to agg 19.
and the other in slot 1 to agg 13-14.
It will depend a lot on different set ups,
as I notice cards can behave differently in different computers,
which I don't know why.
Tweak your aggression, and get your gold spot.
For running without crossfire download this special
drivers
http://developer.amd.com/tools/heterogeneous-computing/amd-gdebugger/#download
and download .msi, if your windows is 32 bit then 32, 64 bit then 64, etc.
After that, you can run both cards without crossfire, and one will be without
drawing your desktop, and doing no graphical work.
That can be a super dedicated card.

Change your gpu_thread_concurrency 6144 to gpu_thread_concurrency 3200.
5770 has 800 shaders, and each shader can run about 4 threads.
the 7000 series can supposedly do 5 threads.
But you have the 5XXX series.
Any more then over 4 per thread is going
throttle, overfilling it will just make it go slower.

AMD Phenom II X6 1090T
8 GB RAM.
2x ATI Radeon HD 5770 Sapphire.
Using Reaper and ScryptMiner.
Reaper's code:
Scryptminer's settings:
No additional parameters.
Doing GPU and CPU (5 of 6, 6 of 6 when idling computer) mining and so far I've got a generous 80-81 kH/s going here.
I'm sure I can get more out of these video cards, at the very least.
Suggestions?
