Is buying DDR4 with a speed over 2800MHz worth it?

[Big-G]

I've looked at the latest edition of Maximum PC and their review of DDR4 RAM... and it seems that buying anything over 2800MHz isn't really worth it due to dicey BCLK overclocking needs...

 

Your thoughts?

2133 is fine. For most uses speed doesn't really matter.

It gives you the ability to make fun of other people who have 1600mhz ram still. If that doesn't appeal to you then 2800 ram isn't worth the extra cost over 2133.

True, I guess

the corsair 3ghz sticks are a good price so that's basically the sweet spot right now.

Apparently there is some evidence that higher RAM speeds can give you better performance with Skylake processors. I haven't looking into it in depth but poke around before you make a final decision.

But still brings about impacts to CPU overclocking

True, could be. These guys from Maximum PC actually found CPU overclocks to become unstable when using memory speed profiles above 2800.

Nope(nuff said)

No point stick with 2133MHz 2400MHz or 2666MHz, law of diminishing returns start to kick in anything above 2800MHz for certain programs/games, it's all dependent on how well the program/game requires memory bandwidth... GTA V and Witcher 3 are 2 examples that love strong CPU and high RAM bandwidth.

it can impact your minimum fps in cpu heavy games, other than that you wont feel much difference. but you can feel the difference for sure. everyone else that still claims you cant feel anything is like people that still say you cant see anything above 60hz and/or still use DDR3.

If you have money and want to use it than yes if you are in budget than no. You won't see monster increase in performance but there will be some increase but you won't be able to see because it will be very small, I think you know that increasing ram speed also increase latency so they almost kill each other but high speed give little diff that can't be seen if you are comparing 1 step high and low ram.

Here i am giving you a link of techspot they tested i3 6100 in 2133 and 3000 MHz, from rendering, gaming to heat output , you have to click next page to see different result. In some case both ram speed give same performance but in some case 3000 is slightly high. Bar graph may show that there is huge in crease in performance but look at the scaling carefully.

Depends entirely on your hardware. Faster memory makes a big difference with iGPU's, but it also makes a big difference in gaming, depending on the amount of CPU overhead you have. This means that the faster your GPU(s), the bigger the difference. Running a GTX 770, i noticed that 2800mhz was the cap, and anything beyond that was diminishing returns. However, reviews with Titan X's from DigitalFoundry shows a steady improvement up to 3200mhz, so it leads me to believe that stronger single cards, and multi GPU configurations will benefit even more from faster memory. A friend of mine proved this theory true when running triple GTX 780's, on his DDR3 setup. Starting at 1600mhz, and ending at 2600mhz (where his kit capped) he kept seeing performance gains in his minimum framerates. Had his memory been capable of overclocking even higher, he might have still seen performance boosts.

 

The point is, faster memory makes a difference. You can check my signature for more info on that, but you can always just test this yourself, by turning XMP off, running default speed, then turning it on and running at the higher clock speeds. A lot of people just spread antiquated information around and pretend nothing has changed. These are the people that have clearly never tested anything for themselves. Ignore them.

That's false. Digital Foundry has shown over and over again that RAM speed matters in gaming when there is high CPU overhead.

It makes a difference with Haswell too, I get much better minimum framerates in GTA V (9.5% better) and Fallout 4 (15% better) on my GTX 970 + Xeon E3-1231v3 system at 1080p after replacing a 2x4GB DDR3-1600 kit with a 2x8GB DDR3-2400 kit. The effect is naturally bigger on Skylake since DDR4 runs at significantly higher speeds than DDR3, but I found the difference to be plain as day on my Haswell chip too.

you can change ram multiplier independently of cpu
