So I went into my BIOS and set my ram to the recommended speed at 2133 MHZ since faster
ram apparently helps boost APU performance.

Anyways I've attached a picture and was wondering if these RAM SETTINGS looked good
and if theirs any other way to tweak them?

I heard that adjusting the CAS latency's would improve performance but i don't
know how to do that or what the right CAS latency would be for my ram.

Its best to run RAM at its default settings so if its latency is 10 with say this RAM stay at 10. http://www.newegg.com/Product/Product.aspx?Item=N82E16820231654

If you need BETTER latency its best to buy the better RAM and use that instead of driving budget RAM to perform better in which it MAY start to perform better but then have random crashes. If your RAM is high quality RAM that can take a better latency setting, you can try it, but I generally run all my memory at its default latencies and if I need better I will buy the next best or the best there is if the price is good.

Here is an older acticle that still applies today:

The only tweaks I have done to my RAM is overclock by 10% in which it started to act up at 13% OC and so I backed off to 10% as a good OC that is stable. But also this RAM is not budget RAM it was higher end gaming RAM and purchased as a matched PAIR of Corsair XMS2 2GB DDR2 800Mhz sticks for total of 4GB RAM.

If you play with any values, write them down before altering so you know where to set them back to. Also be sure to run memtest86 on it to make sure that its behaving and not buggy.
