RAM MAX 64GB?
Hi builders, my hardware has 128gb ram and a video board 8gb.
I tested the windows task manager to know work, but RAM never over 63.9gb?
No matter how big I am, the game at most is slower and slower.
This city just cannot use more than 63.9GB of RAM
What do you think about?

Sorry i'm not english
I translated the text into English using google translation

Im not an expert, but from what i know there are at least 2 things that may limit how much ram is detected:

- you motherboard:
check in the manual or website which ram memories are recommended, and which is the max amount it will recognize. Not all brands will work the same even if they share similar specs. At least thats what sellers and the companies that create the mobos advice. Not sure why, i just bought the rams i read were compatible with my mobo.

- you os:
windows usually cripples the amount of ram that can be detected, depending in the version you are using. ie home edition will detect less ram than a pro version. Tip: linux distros dont usually have this limitations: they will recognize all ram you have installed, as long as its recognized by the mobo.

+ your cpu:
your cpu may be compatible for more ram, but if the mobo cant support or detect as much ram as your cpu, your are stuck with the limits of the mobo.

Another issue that may affect how much ram is detected is a faulty or damaged ram. Maybe one of your ram cards is damaged.

Its the limit of your motherboard:
https://www.asus.com/us/Motherboards/ROG-MAXIMUS-XI-HERO-WI-FI/specifications/

Memory 4 x DIMM, Max. 64GB, DDR4 4400(O.C)/4266(O.C.)/4133(O.C.)/4000(O.C.)/3866(O.C.)/3733(O.C.)/3600(O.C.)/3466(O.C.)/3400(O.C.)/3333(O.C.)/3300(O.C.)/3200(O.C.)/3000(O.C.)/2800(O.C.)/2666/2400/2133 MHz Non-ECC, Un-buffered Memory Dual Channel Memory Architecture Supports Intel® Extreme Memory Profile (XMP) ** Refer to www.asus.com for the Memory QVL (Qualified Vendors Lists). * Hyper DIMM support is subject to the physical characteristics of individual CPUs.

It can only detect 64gb max, but since you installed bigger ram, it could mean they could last longer since they wont be working at 100% of the capacity.

im not sure about that: you show consult an expert about that. Ask what happens to your ram cards if you have bigger ram than what your system can detect. Maybe its not a complete waste.

Also, theres a point in which this game may not improve performance with more ram or video, because it demands a lot from the cpu when cities become really big. So, that means that if you want a smoother experience in this game you may need a server mobo with dual cpu, so you can have a lot of cores to process faster bigger cities.

Those things can be way more expensive than gamer mobo, unless you get a used one and find cheap cpus for it.

well BIOS Version 0805 2019/02/227.98 MBytes

ROG MAXIMUS XI HERO (WI-FI) BIOS 0805
01. Improved DRAM stability
02. Supported JEDEC standard DDR4 32GB memory
03. Updated RST driver
04. Update ME FW

https://www.asus.com/us/Motherboards/ROG-MAXIMUS-XI-HERO-WI-FI/HelpDesk_Download/

and I have asked Asus to confirm that the motherboard supports up to 128Gb
HiMe Feb 17, 2020 @ 9:12pm 
windows task manager shows that the CPU usage does not exceed 40%
HiMe Feb 17, 2020 @ 9:16pm 
It looks like the game is not exhausting my computer performance
It doesn't make much sense to upgrade higher-end CPUs or better motherboards. I don't think the problem is hardware.
@R+5 Feb 17, 2020 @ 9:18pm 
maybe whoever answered you thought you meant if it could read the ram rather than be able to use 100%?

the mobo will detect bigger cards, but it wont be able to use them 100%.
@R+5 Feb 17, 2020 @ 9:20pm 
check from your bios if all cards are detected. if all are detected, then it means all cards are ok, but that the mobo cant use more ram than what its compatible, even if theres more available.

Maybe this could help:

Try playing other games
There are other games that do use more than 64GB of RAM
Burn-in test also confirms that there is no problem with the equipment
So the BIOS drivers have been updated to the latest
But this game just cannot use more than 64Gb
@R+5 Feb 17, 2020 @ 9:37pm 
well, is the model of your mobo the same in the link i wrote? if it is, according to it the limit is 64 gb of ram.

not sure how you measure how much ram other games use, but afaik most will only need 16 gb or less of ram, even recent titles. the only thing that usually improves the performance of most games is better gpu, but cs demands more of cpu with big cities since there are too many variables happening at once.

What do you think about?

Why do you think it will exceed 64 GB of RAM? What is installed?

If you add workshop, your system will get slower and slower. Workshop are add-ons to the game and can use a lot of resources in some cases.

What is being slower and slower? and in what way?

That says it supports 32 GB single sticks. So if you have a set of 128 GB (4 x 32 GB) it should work. If you bought a set of 128 GB (2 x 64 GB) they may not fully work.

Your 0805 MB BIOS is very, very old. 1401 is the newest BIOS available. Upgrade BIOS. Make sure to undo any overclocking if you overclock your system.

Why do you think it should be more? The game uses what it needs. It doesn't go 100% because it can, it needs to be used in some fashion.

Thank you for your answer
I may not write well, please forgive me
..
Why do you think it will exceed 64 GB of RAM?
..
Because I think the game has more resources available, but it does n’t
..
What is installed?
..
More assets and bigger cities. It should use more.
..
How much memory did MemTest86 report was installed?
..
128G.
..
That says it supports 32 GB single sticks. So if you have a set of 128 GB (4 x 32 GB) it should work. If you bought a set of 128 GB (2 x 64 GB) they may not fully work.
..
I would like to ask you some common sense, non-ECC DDR4 memory does not have a single 64G memory.
..
Your 0805 MB BIOS is very, very old. 1401 is the newest BIOS available. Upgrade BIOS. Make sure to undo any overclocking if you overclock your system.
..
What I posted is different from the original design.The motherboard's BIOS version 0805 has been supported by the BIOS.
I did update to the latest version and I did not overclock
..

Why do you think it should be more? The game uses what it needs. It doesn't go 100% because it can, it needs to be used in some fashion.
..
I would write it like this because the previous enthusiastic player questioned that my CPU level was not enough to cope, and the game could not use these resources, but it was not the case from the manager.The maximum usage rate was not more than 40%. Obviously, the resources were not Not fully used.

Please do n’t question because one of my hardware does n’t support
Or
The driver is not installed
Failure caused by overclocking
Or maybe
Operating system is not supported
My other account, The Elder Scrolls V, can use more than 90GB of memory. But in Cities: Skylines NOT
