DDR4 Speed on the Dual-Channel Z170 Platform

3DMark Fire Strike

3Dmark

We see a 0.5% boost going to 2666MHz memory, and another 0.25% boost going to 3200MHz at tight 16-16-16-36 timings. That's probably about as good as it's going to get in our games!

Crysis 3

Crysis 3

Both DDR4-2666 and DDR4-3200 perform better here, with 2666MHz claiming the minimum win and 3200MHz claiming the average win. 

Battlefield 4

BF4

Battlefield 4 gets a slight boost from each RAM speed increase.

Ryse: Son of Rome

A very significant boost can be seen here. This is more than just test-to-test variation. A 4% jump in average and 8% jump in minimum performance is nothing to scoff at, and comes at little cost if running a 2x4GB kit, which as we'll see on the next page works just fine!

Grid Autosport

Grid

We see a slight imcrease in averages but not minimums here, which is umlike many of our other games.

Grand Theft Auto V

GTAV

Even using the built-in benchmark led to too much variation here to draw conclusions, although faster does seem better overall.

The Witcher 3

Witcher 3

We get a big boost jumping up to DDR4-2666, but then the party ends in this, our most taxing title.

Rise of the Tomb Raider

ROTR

Ironic that DDR4-3200 ends up the slowest in this grapically-demanding title. You can't win 'em all!

Now let's turn to memory quantity to see if you take a hit dropping down to 8GB.
