RAM is backwards compatible when referring to the data transfer rate or 'speed'. So RAM rated at 1600MHz is fully capable and functional running at 1333MHz. RAM does have specific voltage requirement to run at advertised speeds. 1600Mhz rated RAM will require more voltage to run at the higher speed. RAM with higher advertised 'speeds' (1600Mhz.) will also require greater or laxed CAS latency and timing settings to achieve the higher speed. High Performance 1333Mhz. rated RAM should require less voltage, have tighter timings and be capaple of OCing to 'near' 1600MHz speeds. Anyway, RAM is backwards compatible so the higher rated RAM should work in the MB. You may have to install 1 DIMM and set the voltage properly in BIOS then install the remaing RAM with the correct voltage applied
This. Very good answer, indeed. Since your MOBO supports:
2 x DIMM, Max. 16GB, DDR3 1333/1066 Hz Memory, this means whatever memory you get, it will run at 1333 anyway. As for the make of memory, there isn't a very big difference between makes and models, provided you are not going to overclock it. I'd, however, suggest that you check other brands as well(instead Kingston and Corsair) such as: G.Skill, Patriot, Avexir etc. Depending on where you live, try to get the cheapest 1600 rated 2x8gb 1.5v memory that you can find.
If you live in the USA, buy that from
Newegg.
If you live in the UK(or somewhere close to the UK) buy it from
Overclockers.co.uk
If those two won't work for you, that's okay, just use them to compare models and search for the same models in other websites.
If you find different kits, with the same availability and price, get the one that is retard with
LOWER timings (CL/CAS is most important, usually that will be 9). If timings are the same, toss a coin for it.
