In our most recent test of RAM modules we mentioned that 16 GB is becoming the standard for many of our readers. Adata sent us two 16GB DDR3 kits from their deluxe XPG series, aimed at gamers and overclockers. The XPG 16GB DDR3-1600 CL11 kit is specs-wise a dime-a-dozen product, but we mean that in a good way. DDR3-1600 currently dominates the market, and with the XPG DDR3-2133 CL10 Adata wants to compete with Corsair, Kingston and G.Skills in the high-end segment.
Let's start with the XPG 16GB DDR3-1600 CL11 kit. The memory modules have a standard voltage of 1.5V and run on DDR3-1600 with 11-11-11 timings. Oddly the modules aren't XMP compatible, but that doesn't matter since the DDR3-1600 11-11-11 settings also sent via the standard SPD chip to the motherboard. The modules have blue heatspreaders which look pretty good in our opinion. We're not as happy about the pricing, however, especially considering these are CL11 modules.
The XPG 16GB DDR3-2133 CL10 kit is of course meant for people that want the fastest possible RAM and don't care about spending a little more. So it should therefore be possible to overclock this RAM. The modules are based on Micron D9QBJ chips and has the same heatspreader as the other kit, but in red. This set is XMP compatible and includes a DDR3-2133 10-11-11 profile. A voltage of 1.65V is required for that speed. The price is more reasonable for this kit, even if it's not the most affordable out there.
