As usual we test the DIMMs at the box rated speed of 2133MHz, but also at higher memory dividers speeds. We then try to find the tightest main timings possible. This usually takes some hours of Memtesting to see if the DIMMs are holding up with the selected timings. Our main test program to solely test the RAMs is HCI MemTest Deluxe. It can be run from within Windows and at multiple instances, to ensure we cover all the free RAM you got. For 16GB I usually test up to 13GB to leave 3GB free for Windows 7 to play with.

The test setup comprises of the following hardware :

 

Asus Maximus V Gene motherboard 0078 bios

Intel i7-3770K CPU at 4.5Ghz (45 x 100)

Asus Nvidia GTX480 VGA

Western Digital 1Tb Caviar Green HDD

Windows 7 64bit Professional SP1 & fully patched

Corsair 1200W AX series PSU.

The results of the Belgian jury are :

1600MHz : CL9-9-9-27 2T 1.5Vdimm: taken as reference as most systems are sold with this ram speed

2133MHz : CL10-11-11-30 2T 1.5Vdimm (box rated VELOCE speed)

2400MHz : CL10-12-12-30 2T 1.65Vdimm (OC )

2600MHZ : CL11-13-13-30 2T 1.71Vdimm (OC)

Getting the stick happily running at 2400Mhz was already a blast. Yet these Veloce rams had no problem either to run at 2600Mhz HCI Memtest stable, which is kinda impressive in my book for an 8GB Dimm kit. Running them 1T was also no problem, but to keep the data aligned we decided to stick with Command Rate at 2T.

Here's a shot of a dummy of that infamous GeIL DBT testing machine. On the right the goal of this machine: To prevent early failure, to warrant operating speeds and test voltages and ensure proper binning of ICs.
