Thread: DDR3 Speed

    Default DDR3 Speed

    What is the best speed to run with the GIGABYTE GA-EX58-UD5 LGA 1366 board ? I assume DDR3-1600 is best, I see others at 1800, 1866, 2000 and 2133.

    See the memory support list on the gigabyte site - this board supports up to DDR3 2000

    There is no "best" RAM speed to use.

    Current socket 1366 CPU's are actually designed to work natively with DDR3-1066 RAM. Newer Lynnfield 1156 CPU's now support DDR3-1333 natively.

    You really aren't going to notice that much of a difference going from 1333 to 2000 etc. Most typically run programs just don't need that kind of RAM bandwidth.

    The problem with going off the QVL is that it hasn't been updated since the board was manufactured. Since then ther have been countless new RAM kits availible that should work just fine.

    All you're looing for is a 6GB kit that will run on low voltages, up to about 1.65V. Speed wise, I'd pick between 1333 and 1600. Also choose a good balance of timings. 7-7-7-21 may be available in both 1333 and 1600 kits. Over all DRAM latency is a combination of timings and frequency. Also remember that some 1333 kits with low timings MAY be able to reach 1600 with raised timings.

    As far as RAM performance goes, it's bottom of the pile really with regards to over all system performance. CPU speed, GPU (if gaming or rendering) and even a fast HDD or SSD are much more important to the over all impression of speed and "snappiness" you get from a new, high spec machine.
