Best Ram speed and Cas Latency for gaming?

[IAEInferno]

Okay so I noticed that people are saying that ram speed doesn't matter when gaming but the amount of ram does.

 

This video proves otherwise for some games.

 

 

 

What would be the best ram speed and CAS latency for gaming?

 

[belfouf]

this video proves that multithread helps, and that a huge speed gap between ram with same CPU gives up to 4 fps more...

 

really, if you have money and you care this much buy 3200Mhz DDR4, but it won't change everything you knew

The video shows a huge increase of 66% and a minimum of 8% fps, what would be the best ram speed and cas latency?

increase, you mean i5 vs i7 ?

No the ram speed differences with the i3-6100 with different ram speeds.

yeah, fake. errors in testing. no way 500mhz RAM makes 40 fps diff.

There will be the nay sayers who are most likely regurgitating the fallacies spread by Linus' flawed video about the matter but there is clear evidence that faster RAM does make an impact on minimum framerates and potentially gives higher average framerates in CPU intensive situations. 

 

Diminishing returns start at about 2800-3000MHz. Latency doesn't matter much as far as I'm aware.

@patrickjp93 hello, is this true?

Okay thanks, so around 3000Mhz would be the best option for faster ram :D.

Until I disassemble the binary, I cannot comment on it with any integrity. While it is POSSIBLE to produce such a scenario, I doubt consumer game programmers have reached that level of competence yet.

Basically. Spending $6-10 more isn't going to make a huge dent in the budget.

this is what happens in reality with every games

So 3000Mhz is the sweet spot, thanks dude.

DDR4 3200 14 is the best currently available for DDR4 latency, even if the bandwidth is not the highest. That said, I have not seen enough testing for the current gen to prove one way or the other. And Linus' videos can go out of date every 6 months. That does not make him wrong at his point in time in context.

yeah 3000 makes a gap, which is reduced further, note that the smallest the CAS (CL) the best perf

Yes, thanks!

Oh yeah, I noticed that the CL on the 3200Mhz one is at 16 and lower CL is better if I'm not wrong?

 

So a 2x8gb 3200Mhz 15CL ram kit would be faster than the 3000Mhz one and thus better fps!?

a 2x3200 CL15 would be more optimal than a 2x3000 CL 15 if you have a latency-sensitive workload.

There's a 3600 c15 kit out as well, which IIRC has better latency & bandwidth overall. It's a bit pricey though.

G.Skill was also supposed to be dropping a 3400 c14 option on us, but I haven't seen anymore on it.

To be honest I just game all day, I'm trying to find out the best type of speed for gaming .

Make sure your motherboard supports the RAM speed and that you don't exceed the amount of supported ram! The reason the video shows that you gain tons of performace with faster ram is because it's an i3. With an i5 or i7 the story is a bit different.

I see, I'll make sure to check the compatible ram speed of the motherboard :D.

Since the i3 only has two hyper-threaded cores, it'll gain hugely from a faster (or technically more bandwidth) and a lower CAS latency (to reduce the time between requests). The i5 gains a little less than the i3 with it's four cores and higher cache. i7's gain the least as they, once again, have hyper-threading and larger cache.

 

I usually recommend getting 1866/9 DDR3 and 2400/15 DDR4 with i7's and i5's, but any i3 system that i build gets 2133/11 DDR3 or 2800/17 if the price isn't too far off from the bases for the platform.
