4GBRM vs 4GBECO on P7P55D@i7-860

[tolian21]

Narrowed my choices to two 4GB (2kit) RAMs that look identical to each other:
F3-12800CL7D-4GBRM 7-8-7-24-2N, CL7, 1.65V
F3-12800CL7D-4GBECO, 7-8-7-24-2N, CL7, 1.35V

I am planning to run this at 1600 MHZ, should I go for lower voltage one? Will the lower voltage choice provide better latency doing memory read/write ?

ECO all the way. You can do some real overclocking with this motherboard, CPU, memory. ;-)

The lower voltage allows easier/better overclocking. The CPU and memory controller voltages/temps will be lower as well.
