Any optimization tips? (Scrypt)

[PhelanWolf]

I'm scrypt mining using multipool.us
I have a Asus Radeon 5550 1gb  (http://www.newegg.com/Product/Product.aspx?Item=N82E16814121407)
when I'm using the PC I set it to dynamic it and it drops to about 9 KHash/sec but makes the PC usable, but I'm not on it that much
when I'm not on it I've been just setting intensity to 13 and get about 45KHash/Sec, any settings that might help me squeeze a bit more out of it?
It runs at about 65-70C at intensity 13, I got the card because this PC is a HP and has a shitty power supply and it was the fastest card I could find (back in 2010 lol, if I had only started mining then) that didn't require an external power adapter (IE it's powered straight through the bus on the motherboard)
I also get about another 20 KHash/sec CPU mining with a Athlon II x4 635

Google is your friend, lots of help out there on the various mining software and cards.   I dont have anything specific to the Radeon 5550; however, in general you'd work well with something like CGMiner (if the 5550 supports openCL) and playing with settings.

Play with these switches:
-I 19  - your intensity, if you get too high and this is your display adapter (not a headless adapter) you will find the desktop unusable and you will start to get HW errors.. back it down to something that makes sense for you.
-w 256  - work size -- bigger isnt always better..  64, 128, 256, etc..
--thread-concurrency 8192  <-- if you have this number too high, cgminer will not start.   make it as high as possible. 

you can also look at --shaders which tries to optimize settings based on shaders

These can be helpful too:
#temperature control  -- set these to save values for your card.   Below is what I use for my 7950s.
--auto-fan --temp-cutoff 95 --temp-overheat 85 --temp-target 75 --temp-hysteresis 3 --gpu-fan 0-85

#overclocking
--gpu-engine 1050 --gpu-memclock 1550  (these will be way to high for your card, but do some reading and play.   If your card gets HW errors or crashes, try lower settings)
