The E30200A DDR3 from Exceleram are some really affordable 8GB memory modules that we can use in case we are running lots of virtual machines, Ramdrives or other memory-consuming applications. These are not too overclockable, so the maximum stability we could obtain only at 11-11-11-30, 1600Mhz, by running with two out of four sticks.
CPU : Intel I5 2500K Retail
CPU Cooler: Noctua U12P SE2
Motherboard : ASRock P67 Extreme6
RAM : G.Skill Ripjaws F3-12800CL8D-4GBRM
Video : Sparkle X460 Calibre 1GB
Power Supply : Cooler Master 850W
HDD : Seagate Barracuda 320GB 7200.10
Case: Cooler Master ATCS 840
During the tests, the CPU speed was set at 3.3GHz and Turbo was disabled in UEFI. Testing with the stock timings was possible only at the rated speed; reaching 1600Mhz was possible only when installing two modules and relaxing the timings to 11-11-11-30; with the same settings, when installing all four modules, even if the voltage was upped to 1.65V, the system refused to boot. After each modification, HCI Memtest (Windows utility) was ran with 4 instances for about a half an hour, to determine if the system was stable or not. What was interesting with these modules was the fact that they did not increase their overclocking ability by upping the VTT, RAM voltage.

The pre-programmed timings and frequencies can be also found by using AIDA64:
