16 GB DDR4 3200 Cas 16 vs 3200 Cas 14 real world difference

[DukiNuki]

hey guys

i know 14 Cas is faster but its also more expensive and price difference is a bit high , will i notice ANY difference in FPS if i go with 14 cas over 16 cas ? i know benchmark tools will show the difference but what about real world gaming ?

notice how faster ram made no difference , maybe that's because Latency also increased as the Mhz got high which made the difference unnoticeable

but 3200 14 vs 3200 16 use the same mhz with different timings that got me thinking whether their difference will be noticeable in real world scenarios or not

Strictly gaming, probably not, if multi-tasking and using DRAM intensive apps, might see it more

why probably not ? how can i be sure ? cause if its a matter of up to 5 fps then i'm going for it but if its maximum of 0.5 fps then no

Then it would come down to testing, would depend on the game - some games DRAM speed/performance doesn't really show up but in big jumps say low freq to high freq, other games tend to love fast DRAM, like Fallout 4. On my Skylake I got 32GB (4x8GB) of TriZ 3200/16 and was great, then later grabbed a set 3200/14 (2x16GB and it was even better - overall system performance. Also, some will 'see' a difference, many others won't. I play with different DRAM a lot at my business so I can often tell a difference just in the general use of my rigs

ya i get what you say it feels smoother even though you might not see a difference in fps , but did you gain any fps ? i mean did you use fraps or anything to measure how much frames you gained by cas 14 ?

and what if 2x16gb made it work better than 4x8 ? oh that s just stupid 😀 ignore that noob comment

 

[Tradesman1]

I don't game, and yes 2x16GB can be smoother as it's less stress on the MC (memory controller) than 4 sticks. I gave them a try as am considering going 64GB with a 6700K build

 

[DukiNuki]

one more question , what do you think about DDR4 16GB 4000mhz ? have you tried it ?

 

[DukiNuki]

can you please give more detailed explanation about how much it can help ? i'm going with Single GPU setup like GTX 108o + i7 6700k ( Stock Speed )

As said, on gaming 'it would come down to testing, would depend on the game'
