RAM MHz Difference

[DragonDope]

Hey, so I'm buying a laptop soon, and I have 2...what are they, voltages(?) choices for the RAM in the laptop. 2133MHz and 2400MHz. For gaming, music/audio production, and video creation/rendering, which would be better suited for those tasks. Also, the 2400MHz version of 16GB costs less than the 2133MHz

 

Thanks in advance for answering!

Clock frequency, not voltage.

 

2400 MHz will help a little bit here and there, not a really noticeable difference though. Also worth checking if it's dual channel, like 2x8GB.

Ram speeds barely make a difference.

Makes literally 0 difference unless you're benchmarking even then its negligible go for the cheaper one!

Yes it does. Linus has a lot of good advice, but he's wrong about the impact memory speed can have. Also that video is quite old, there's new tech available now.

Actually makes a difference if your using a slow cpu for example the G3258.

Its gonna cut time off for video rendering, if you have higher speed Mhz+ more ram

Another video that doesn't prove the point he tries to make. Also not a true apples to apples comparison.

My counter my good sir:

[Sakkura]

Here are some game benchmarks where memory speed obviously matters. Many non-gaming workloads are even more memory-dependent.

Can you show me some evidence where ddr4 makes a noticeable impact over ddr3? I'm genuinely interested since you seem determined to prove your point...

For the love of all that is holy. How can so many people be wrong? 

 

Stop taking Linus' word as facts people. He was wrong about memory speed, still is, and probably always will be as he seems to ignore every request to redo the test. How hard is it to test it for yourself? Just load JEDEC default speeds, test a game, then load faster XMP and test again. It's really that simple. Read my sig, look at this thread, watch this video, just do something.

If your laptop supports faster memory, get the fastest that you can get. If it is using an integrated GPU, it will help. If it's using a dGPU, it will still help depending on the amount of CPU overhead. The fact that you mention rendering is more than enough to justify the cost of faster memory, as bandwidth is very important in raw compression.

But we´re arguing about RAM speed, not DDR4 vs DDR3...

Don't tell me Linus was wrong about that too? lol

[Enderman]

just get 2400

in some cases it does give a bit of an improvement

no reason why not to get it if its cheaper

Not saying anything, other than the fact that his quad channel memory is slower than my dual channel memory. That should be enough of a red flag to tell you his testing methodology is broken somewhere.

If the 16gb 2400mhz ram costs less than the 16gb 2133mhz ram then but the 16gb 2400mhz ram. You get higher speeds which may marginally help for video production (not gaming), for less than cost of the slower ram. Why get less, if you don't have to, especially when the better stuff costs less?

Coincidentally, it is 2x8GB. Does that make a whole lot of difference?

 

Doesn't matter too much though, as they don't offer 1 16GB RAM solution; but I think this thread has me coming to the decision to get the 2400MHz one. Also, thanks for the terminology correction, appreciate it!

 

Thanks for all who answered! I guess this one's a solved case.

2x8GB is good because 8GB sticks have Rank Interleaving. Which essentially means you can read from one rank while still writing to another. It's free bandwidth. Rank interleaving on 4GB sticks is almost non-existent outside of ECC. Very, very rare.
