Any suggestions on what might be a better match for this processor and the CH5 board. Im also finding it seems like two sticks is the way to go for best OC results, so would 2x8 in a higher speed be good, or 2x4 with a faster speed be the better way to go
It's unclear why you believe your RAM is "causing limitations" Perhaps you can elaborate?
The BIOS for your FX mobo may have more RAM options but it's unlikely you will see much system performance change regardless of what settings you use as DDR3 RAM is not a system bottleneck like DDR and DDR2 RAM was. Your RAM usually has a label with the proper settings or it's on the package or the RAM maker's website. These settings are where you should start including setting the RAM voltage properly.
Typically people seem to get better performance with two DIMMs over four DIMMs because it takes longer to access all of the data cells with four vs. two. It's a minute difference but it may show in benchmarks but not actual system performance. Two DIMMs may also allow you to OC the CPU/RAM slightly higher - might. CPU clockspeed is far more important than RAM speed for increased system performance except with AMD Llano CPUs where RAM speed helps a lot because the CPU and GPU get to use the increased RAM frequency
Most people are happy with 4-8 GB. of RAM. Unless you have a need for more RAM there is no system performance advantage to greater than 8 GB. unless you are running huge apps or many apps concurently.
