Avoid DDR3-1333 (and DDR3-1600)

While memory speed did not necessarily affect our single GPU gaming results, for real-world or IGP use, memory speed above these sinks can afford a tangible (5%+) difference in throughput.  Based on current pricing, after the Hynix fire, it may be worthwhile, as memory kits above DDR3-1600 are now around the same price.

 

Basically, from what I can tell, for gaming increased RAM means nothing on Haswell. But for heavy work load stuff, it's better. I guess most of us knew that.

 

 

For discrete GPU users, recommending any kit over another is a tough call.  In light of daily workloads, a good DDR3-1866 C9 MHz kit will hit the curve on the right spot to remain cost effective.  Users with a few extra dollars in their back pocket might look towards 2133 C9/2400 C10, which moves a little up the curve and has the potential should a game come out that is heavily memory dependent.  Ultimately the same advice also applies to multi-GPU users as well as IGP: avoid 1600 MHz and below.

 

So basically if ultra books that use 1600 MHz and a iGPU, they're doing it wrong is basically what I'm reading.

My notebook (specs in sig) has a a10 and has 800mhz memory...

Are you sure it's not 1600MHz?

 

CPUz shows half of the actual speed.

Im using speccy.

 

EDIT: must be 1600mhz, just checked on cpuz
