Ram speed - 2020 update

[james111333]

I'm building a new system soon for DCS VR, I'm thinking of an mATX MB for my 10900k and 2080ti but one thing I am craving other than the CPU upgrade from my 4790k at 4.8GHz is faster ram, both the jump from DDR3 to DDR4 and also from 2200mhz to 4400mhz, I found that for my use, DCS loved the increase from 2000mhz!

 

 

 

All of the posts I am reading seem to be outdated due to the insane cost of RAM in recent years but now it's super cheap, I assume the consensus has changed.

 

 

What will see the best returns, either 16GB 4400mhz ram or 32GB 3200mhz for DVS in VR, they are about the same price and this build is basically just for DCS and Firefox! I would rather just use 2 RAM slots so if I go for the 16GB I probably wouldn't want to add another 16GB further down the line.

 

 

Thanks for any input, I know the question has been asked lots before but now RAM is so cheap I would expect opinions to have changed in our shared goal of eeeking out those jarring frame drops and (Orange) frame times. :joystick:

Well I had this same question and it seems nobody Truly knows or if they do they aint telling us.. I guess there is a point to which the speed balances out as too what that speed is I have no clue but what I do know is you should plan on getting minimum 3200mhz and 32GB Memory..

 

I ended up with 3200mhz but my motherboard supports upto 4400mhz. I would like to know the true answer as well..

 

there has to be a point where as fast as the memory is where does the CPU cutoff that speed at?

James, 4400 MHz and above ram is primarily about showing off and synthetic benchmark results. Just google 4800 MHz ram gaming results and you will see, depending on the title, that you will get about 1 to 3% more FPS with 4800 over 3200 MHz, but the price for the 4800 MHz is far higher than 1 to 3%. Once you go above 3200 MHz in a Z390 platform, the returns diminish so much that you end up spending hundreds of dollars for, ... say, ... a 1.45% gain. (as an example)

 

No one can tell you what 4800 MHz can do over 3200 MHz on the Z490 platform bc it is not out yet. About a year back, I did briefly try 4400 MHz vs 3200 MHz on a Z390 ASUS ROG Hero board and in DCS with the Reverb headset, I averaged about 1.32% more FPS. (I do not remember the exact figure but it was something like this.)

 

Because of the actual bandwidth rates, you will be better off with only 2 dimms vs 4 dimms. As to your exact question, I would recommend you purchase a 32 GB 3200 MHz kit (and you want two (2) dimms of 16 GB each). This will give you 99% of the 4800 MHz kit at hundreds less.

 

 

Hah looks like you answered my question I posted in your Hardware thread so disreguard it thank you.. :)

Pretty happy with my 3200 MHz G-Skill CL14 ram. I have not run any other ram on this particular MB to compare though.

Get Samsung B-Die RAM. Good RAM is all about finding the highest frequency with the lowest timings and then tweaking in BIOS.

B-Die 3600MHz at CL14 is about the best you can get. Can overclock it to 3800-4000 MHz if you're good.

Thanks for the info, especially your test findings, I understand we know very little about z490, it appears to accommodate faster memory but if there are no real life gains in DCS, I would be better off spending it on fancy beer haha.

 

 

It clearly doesn't scale well as adding 500mhz at the lower end (and looser timings) gave me 15fps which was all I needed to stay nicely in ASW with my Rift.

 

 

It's heartbreaking to see my 2080ti at 60% load on my HP reverb with 30ms latency so I'm hoping that will change with the 10 series.

Thanks, your system is a beast, although what kind of utilisation do you get in the Titan in DCS? (You should also get a Reverb haha, it must be like owning a Ferrari and installing a muddy landrover windscreen in it with the Vive:lol:)

 

 

You've opened up a can of worms now as I was unaware of B die ram, I'd seen it mentioned in other scenarios but hadn't taken much notice. What kit do you have specifically?

 

 

 

So would 16GB 3600+ C14 B-die be better for DCS than 32GB 3200 C16?

 

 

It will be on a 10900k watercooled with custom loop and 5x120 rad area and aircooled 2080ti until the 3080ti comes out.

 

 

 

Thanks for everyone's input!

Get the 32 GB of RAM. RAM timings make minimal, if any difference in performance. Running out of RAM on the other hand...

At the moment with settings pretty much max (no shadows though) I never run out of ram as I close browsers etc. That's with 16GB 2400mhz.

 

 

With a better CPU and maybe shadows on, unless anything else changes, would I start needing more RAM? I only free fly with a mate with minimal other traffic on my servers so would that add demand on my RAM? There's normally no more than 2 or 3 additional aircraft on top of our F-14s
