Hi. I just put together a system, here are the relevant parts.
2x4GB G.SKILL ram 1600
asus p8 h670m evo mobo
The thing to notice is that the mobo supports max 1333mhz ram (am I wrong?).
My question is whether it's worth it to upgrade the mobo to something that supports 1600mhz ram (will I notice a difference if I'm doing long numerical calculations in c++). Or should I get ram rated at 1333. Or should I leave things as they are? Opinions would be great.
Edit: I just talked to a guy at a computer store. He says that my mobo should be able to support 1600 mhz ram if I overclock. Is this true?
* 4 x DIMM, Max. 32 GB, DDR3 1333/1066 Non-ECC,Un-buffered Memory
Dual Channel memory architecture
* The XMP support (MAX 1333MHz) is subject to the physical characteristics of individual CPUs and the package of DRAM. Please refer to Memory QVL for details.
The results are obvious: going from one memory speed to the next, e.g. from DDR3-1066 to 1333, does not provide major benefits. Even the replacement of slow DDR3-800 RAM by DDR3-1600 memory will mostly yield disappointing results. While the performance advantage is measurable, it is never noticeable.
Of course this is a little late and the poster has probably found his answers eslewhere. But this does benefit me, as I just learned that I don't have to spend money on 1600 ram and a mobo that supports it.
