I am no pro at ram overclocking or makes but what I could add to the mix is all them brands are pretty good and a couple of them offer lifetime guarantees so I would say get the one with the lowest CL for its respective speed at the price you are looking for.
When I built my pc the only available ram at the price I was looking for was this gskill ram with CL11 @ 2133, my next upgrade would be to get some CL9 or CL8 if that's possible with same speeds or close to it.

Quote:

Column Address Strobe (CAS) latency, or CL, is the delay time between the moment a memory controller tells the memory module to access a particular memory column on a RAM module, and the moment the data from the given array location is available on the module's output pins. In general, the lower the CAS latency, the better.

Whats wrong with you're current ram what CL is it ? as u can just add a block or 3 to that ? tahts why I suggested a low CL ram for yourself as you wont be overclocking.

Crucial (preferrably something made without heatsinks) or Kingston HyperX. All the others have about the same standards, which tend to be lower.

H61 motherboard uses/sets RAM to 1333. Since you have a G'Skill Ripjaws 1600 in your sig, just find another if you can (I assume CAS9 1.5V). Otherwise any of the above on sale, 2x4GB kit CAS11or less, 1866 or 21xx, if you may want to use on future board. Faster RAM should allow lower CAS settings in BIOS. Using stock cooler, heatsinks do not matter unless you are worried about compability with aftermarket coolers.
Asus P8H61-M LE Motherboard only supports 1333, note usually 1600/1866 is less expensive, and will downclock for you.
G'Skill Ares 1600 CAS9 1.5 V at $70 seems the least expensive at the moment
