What ram should i prefer ?

[DeathSmile26]

For unreal engine do i really need an 32 gb ram or more or i can work it out with 16 gigs.The ram i am thinking to use is G.skill TridentZ DDR-3200.

Plz tell me if this ram is necessary for an indi developer like me.if there is some better choice plz reccomend. It would be good if i don't need 16 gigs cause i could save the money for other parts.

I would recommend you to get 32GB.

For developing I would think you might want the 32, 16 is plenty for playing games but developing them could easily take a lot more than playing does. Depends on how graphical of games you are developing though if it's low poly-count stuff then 16 might be plenty for developing even.

so 32 it is thanx eric6

RAM speed doesn't mean much if you get too high of a CAS latency.

what is cas latency? plz enlighten me. i don't know much about hardware details as i am right now a beginner.

Latency is the number of frequency clocks that it takes to perform an action.  Basically if you had 4mhz with a 1 or an 8mhz with a 3, the 4 would get more work done since it has less down time that isn't doing work.

Doesn't really matter either way.

For time sensitive tasks like delivering graphics frames it most definitely does.

[DeathSmile26]

so if i get a ram of DDR-2800 it will work the same as DDR-3200

 

i am about start developing games for ps4 and xbox1 with my team in 3 months time so will the ram speed make difference.

 

even i may use after effects and may keep about 3-4 programs open at that time. like 3d max etc

yeah, doing that for capacity, go with the 32, I doubt you would need 64 but 16 doesn't sound like enough for that workflow. I'm actually trying to get help with deciding on speed so I'm not really much help there.

Not really.  Going from say,  cas 14 to cas 18 is only 4 cycles difference.  In modern 2400mhz ddr4 is 4.16*10^-10 s,  or 416 picoseconds.  That is far from the limiting factor,  which is most likely going to be the cpu or memory controller anyway.  Plus,  we are already have quite a bit of bandwidth in typical dual channel ddr4. These are not  the ddr or sdram days. 

 

It would only  help in situations where you cpu is already at the very limit.  Not going to happen in gpu bound stuff like gaming or game development.

And I would not disagree with you if we were not talking about on chip graphics.  Having fastest system ram isn't a very big deal anymore, but when the GPU on your CPU uses the system ram as the video buffer, doubling the effective bandwidth with dual channel will make a big difference.  Latency and frequency will also make a difference but not as much unless the change to the overall bandwidth is the same.
It's like how the top of the line cards usually have HBM, then gddr5x, gddr5, ect.  Because bandwidth does matter.  System ram simply does not have enough bandwidth to be video ram.  That's why you lose such a large amount of your frame rate if you fill your discrete graphics ram and have to use system ram.

It does matter in graphics,  hence the push for more and more bandwidth in gpus (gddr5x,  hbm2,  hmc) ,  but not cpus really.

This entire thread is about him maximizing the performance of his onboard graphics until he can buy discrete.

Where does he say that?  I have seen literally no mention of an igpu

Holy crap, I've been ill and still have a bit of a fever.  I thought this was the thread the person asked if they could run 3 sticks of ram and still get the best performance out of their iGPU.  Probably should have read to the top.

Escuse me,

of course i want maximum performance from my gpus

 

The reason i asked about the ram is so that if it would hinder the performence on my development and other stuff and if it does by how much?(not the exact number but words like little bit, some, a lot are fine.)

Assuming you are using a dedicated gpu ( which you should for this kind of work) ,  then system ram speed will have no bearing on gpu performance.  

The only time it might help is if you are using intel hd graphics.
