Do I need 32GB of Memory now?


Recommended Posts

  • ED Team
I currently have 16 GB of RAM, but would I benefit a lot more from having 32GB and how would this benefit me? Thank you!

 

No, I am still rocking 16GB, would I like more, suuuure I would. But I am not rushing out right now to do so. Even with the current issues, I still dont max out my RAM 99% of the time, if not 100% of the time.

The RAM supplier suggested that I should have bought all 4 as a matched set.

 

Always the best course. You might get two sets to work together but not 100% of the time.

@ FragBum, gotta ask.

 

Why are you running iTunes and Chrome while flying in DCS? It unnecessarily bloats your system resources. Just seems odd is all.

 

Because I can. :D Besides the publishers didn't put a sound system in any of the helis I would have expected at least an 8 track in the Huey as an option. :P :megalol:

 

Seriously though,..

 

DCS 8.5ish GB (up from 3 to 6 in SP)

 

Rift 2GB (up from 0.5 +ish in SP)

 

Windows 2ish GB

 

The rest divi up whats left, the CPU doesn't really notice itunes (itunes runs on a mac mini with os server) and makes no noticeable difference to FPS, which I do lock at 45FPS and it's smooth as apart from lag on server but thats another story.

 

All testing was done without itunes and chrome they were added latter and no noticeable change in performance.

 

Again I'm not telling anyone you need 32GB this is just my observation.

Control is an illusion which usually shatters at the least expected moment.

My ordered 16GB arrives tomorrow. I have 16 GB installed and no issues with SP but busy MP like Blue Flag in 9 out of 10 cases doesn't even load.

I'll share the feedback if more RAM did actually help. If it matters - OS and swap file are on dedicated SSD, DCS on another SSD drive.

Question though - and sorry as it had been asked billion times. Should the modules be deactivated before installing additional RAM?

Be interesting to what the outcome is, I have always had 32GB with DCS, a bit of a late comer to the party. :)

what is your RAM usage in DCS if you turn the page file off?

that would tell us how much windows is shuffling to disk :)

I know this isn't a hardware forum, but for those that have gone from 16gb to 32gb, did you just add another 2 modules, totalling 16gb or did you have to replace your existing RAM with 4 modules, totalling 32gb. In the past I have had issues with unmatched pairs and wondered if this was still likely to be a problem?

 

I have 2 x 8 and 2 x 4 totalling 24 gigs of ram and no issues at all, I just slapped it in my rig yesterday and it worked perfectly.

Yea, as cichlidfan said... it's not 100%. Chances are as long as you add the exact type/brand/model of RAM you shouldn't have issues... but you could. Once you start mixing other things like size/speed/etc you are upping chances of having some very strange issues as time goes on.

I second FragBum with all he said. My findings are very similar.

 

My usual RAM usage in MP is about 12-16GB + ~30GB swap, sometimes my RAM goes up to 22-24GB.

 

I have it all on HIGH/Extreme/DS(MSAA4x/FullShadows/Dirt/B.E./ etc...

 

That may up the RAM too, never tried on LOW or MEDIUM yet.

Interestingly and I can't remember exactly what tabs I had open on Chrome but i'm using about 1.1GB less with the pagefile disabled?? I may need to do some better testing but yes less actual RAM perhaps no overhead for data structure representing the pagefile and memory I don't know.

Maybe less people on the server when testing although DCS and Rift look about the same usage. The other interesting thing and I need to formulate some testing the GPU doesn't seem to be working as hard, hich means I could wind the settings up a tad maybe,.. I'm tempted to try 64GB in this rig now,..mmmm

Well maybe not I just checked the price of RAM WOW! That's nuts it's like double what I paid?

 

Nope I just checked my income it hasn't doubled,.. :cry:

Anybody here with unequal RAM Slot Settings who can report his DCS behaviour?

 

I have the following DIMM pair Setting:

 

DIMM O Slot : 8 GB

DIMM 1 Slot : 4 GB

DIMM 2 Slot : 8GB

DIMM 3 Slot : 4 GB

 

- >equals 24GB with same speed and same size configuration -> corresponding to the appropriate DIMM Slot

 

 

I grabbed another cheap single 8GB RAM stick on the Internet recently and am thinking of adding this instead of one 4 GB Slot.. which would total up to 28GB but would mean an uneven size pair ..

 

 

question: can this be recommended or simply non-sense as the uneven size setting isnt adding any real surplus to the system?

 

 

(@ Mods: pls excuse if this post is too much hardware related here, I'll not broaden this any further )

Generally you should use both complimentary slots with the same size sticks like you already have, mixing RAM in slots is more a function of your mother board so it is not easy to determine. You could try either mixing it up and see if it works, no guarantees.

 

Your more likely to get away with base memory clock with miss-matched RAM generally the mother board will throttle to the lowest speed, but it's not always going to work correctly.

Thanks , appreciated !

Yeah, will give it a try.

I think BitMaster might be able to help here more so with practical tests to verify operation, however if the system boots that's a good sign right. :D

You can also check the memory support list of your motherboard and see what type of ram it accepts and in what configuration.

 

If anything it will run if it boots at the frequency of the slowest stick.

Well, all my RAM blocks should have the same speed, as the specs & manufacturer (Corsair) is exactly the same.

Spec of all my blocks: -> "DDR3 1333 Mhz CL 9-9-9-24"

It may work, but the "extra 4GB" of the new module will remain in 64-bit single channel mode, all 4 modules will go 128bit with as much memory as their twin-sister on the other bank.

 

example:

1: 8GB -->16GB@128bit with #3

2:4GB --> 8GB@128bit and 4GB@64bit with #4

3:8GB

4:8GB

 

edit: I would only try this if you can give the module back, chances are high you won't succeed.

I would try it but I'd also be weary in case you could not return the memory. Luckily for me I added 16gb which happened to be the same exact model down to the serial number and it's been fine on my board. All modules running at 3000mhz.

 

But in the future I would buy a set of 4 matching sticks and save myself any trouble.

A lot of times it has to do with your motherboard. Mine is a z370 Asus brand which usually the newer ones have support for them. It will vary on the mobo brand too.

Ordered RAM arrived today and I had an opportunity to do some simple tests.

Starting DCS and joining a Blue Flag server with a clean booted Windows 10 and just the Track IR running.

 

With 16 GB

DCS loads for around 4 minutes, eventually showing only partially (not fully rendered) role selection table and finally failing by exiting back to main menu and staying unresponsive. No other option than just forcefully close the application.

Memory RAM max / peak total commited - 12 GB / 22 GB

 

With 32 GB

During the first try DCS fails in similar way to join the BF server as in case of 16 GB RAM but now it exists back to main menu after around 5.5 minutes.

Memory RAM max/peak total commited - 12.5 GB / 21 GB

 

Second try - after the first crash, without restarting the PC. DCS loads role selection table in around 1 minute. The table screen is almost not responsive - FPS counter shows 1-2 FPS only. It takes around next 2 minutes to get into the cockpit and arrive to stable, normal FPS.

Memory RAM max/peak total commited - 15 GB / 23 GB

 

Conclusion.

Non decisive at the moment but looking on the numbers 16 GB should have been enough for DCS to load. 32 GB didn't seem to solve the problem. I think the issue is also connected with loading time which may also depend on the internet connection. Or just the MP loading algorithm needs fine tuning. I had no issues while playing SP DLC campaigns with 16 GB.

 

If that matters, I have 2 SSD drives - one is OS and swap file dedicated only, second used by DCS. GTX 1070.

Okay now try turning off your page file, I'm not sure any amount of memory will help getting into a server currently but I do note my GPU RAM goes from about 8.5GB in SP to pretty much all 11GB in multiplayer, hence system gets busy doing extra stuff. As well SP gets upto around 6GB and MP around 10GB of system RAM there is a lot going on.

 

Anyway I tried DCS with page file disabled (had to reboot PC) and seems better, interested to see if you get the same result. My GPU usage actually seemed to drop for same results?? Further investigation required here.

 

As well memory usage was down about 1GB but to be fair I didn't have exactly the same things open with exactly the same tabs etc loaded,..
