Higher freq DDR4 - Any benefit?

Admiral Huddy · 20 Oct 2015 at 14:04

Quick question.. I was wondering if there's any real point in buying 3600MHz over 3000MHz, not the the cost is anything as there's little between them.

Will the higher frequency be a problem for the Z170A chipset?

Bigger number is always better

Can't see a problem running those speeds - If there is just add volts

What's the difference between DDR4 2400hz to 3000hz. I know 3000hz is more expensive.

So basically ram speeds don't matter at all gaming. This is good to know. Cheers

same with ddr3 , higher clock but close to zero improvement in games

I wonder how much of the speed increase is lost due to having to increase the timings?

I would suspect none, most of the timings are cycle based (e.g. CAS) so increasing the frequency compensates for increasing the timings. I.E. there might be more cycles but the cycles happen quicker.

3600 compared to 3000 DDR4 makes about as much difference as going from 1333 to 2133 DDR3... which is basically absolutely no real world difference.
RAM speeds are just marketing, you really see no tangible benefit outside of sythentic benchmark programs

Sorry for the late reply. Thanks for the advice

As far as I'm aware, Skylake scales quite well with faster ram - x99, not so much.

So what's a good set of timings and RAM speeds for a gaming rig? I've been asked to spec up 2 gaming PCs, I was looking at i5-6600k with an Asus Z170 Pro Gaming board?

Cheers

I would say the sweet spot for Skylake DDR4 is 3000hz.

what about timings?

If you're just gaming it doesn't matter

Fair enough, thanks for the feed back

It's because the caching system on an Intel CPU is so good.

P4Clock · 9 Nov 2015 at 15:50

depends on the use of the system?

just day to day/gaming. No just buy supper cheap stuff.
Benching all day then again NO lol lower times would be better than faster ram if it's only faster by a little like in this case.

AdamL93 · 12 Nov 2015 at 12:53

I thought it all depended on the latency and timings of the rams as well as the frequency.
