Would appreciate any info or advice about performance differences in RAM speeds for running Photoshop, Premiere, Lightroom, etc. My mobo has 4x2GB which I want to replace with the maximum 4x4GB. (Standard settings; won't be overclocking or tweaking voltage.)

  • Currently installed sticks: Four 2GB G.SKILL 240-Pin DDR3 1333 (PC3 10666)
    8-8-8-21 / Cas Latency 8 / Voltage 1.5V
    Motherboard: Gigabyte H57M-USB3
    Samsung SSDs, Windows 7 Pro 64bit
G.Skilll support recommended only one product for my motherboard, DDR3 1333 (PC3 10666) with timing 9-9-9-24-2N, Cas Latency 9 and 1.5V.

Would I see any real world performance difference between DDR3 1333 and DDR3 1666? Do I need to worry about differences in timing and latency?

Should I buy 1666 or something faster -- instead of what GSkill recommended? Is the RAM speed worth extra money?

Thanks.

Firslty, stay away from 4X4GB config, no upgradibility and it stresses the MC more, better off with 2X8GB which'll have space to upgrade in future w/o discarding any sticks.

Secondly, feel free to go with 1600/1866MHz modules, they're of same price and your MoBo won't have any compatibility issues.

Thirdly, Photoshop has little performance increase with 1600MHz+ sticks, not considerable, its a bit more in Lightroom and Premiere.

Lastly, look for less CL, more MHz, lesser the CL, tigher (better) the sticks, inverse with MHz, more the MHz, faster the memory.
