Upgrading to 32 GB RAM

Looking at your PC specs, why not get...8 / 16 / 8 / 16.....48GB ram?

You can likely just add to it if you take reasonable care to get the most compatible sticks possible, paying particular attention to voltage.

But any number of people will tell you that is foolish and you should go buy two new 16 GB sticks.

Is the current RAM in the QVL for the board (ROG STRIX B360-H GAMING Memory / Device Support | Motherboards | ASUS Global)?

If yes, has Asus tested it for compatibility with 4 DIMMs? If yes, can you buy two 8GB DIMMs that are identical to the currently installed pair? If it's yes to all, buy the identical RAM, and you should have no trouble.

It has been a long time, but I have mixed RAM in the past. I had to do a couple of things to get it to work. One was to manually set the RAM timings, rather than relying on the SPD (serial presence detect) chips. The second thing was to back off on the CAS latency one tick.

The approach that should be most free of potential problems is to buy two 16 GB DIMMs, and replace the existing RAM. It's only money.

Before you spend your money, I suggest you use Task Manger to check how much free RAM memory you currently have. Few applications need as much as 32GB. My laptop has 8GB and is currently only using 3GB.

A computer that I got from HP came with different manufacturers:

Code:

C:\WINDOWS\system32>wmic memorychip get manufacturer, capacity, partnumber, speed, memorytype, devicelocator, formfactor
Capacity    DeviceLocator         FormFactor  Manufacturer   MemoryType  PartNumber        Speed
8589934592  Top - Slot 2 (under)  12          Hynix/Hyundai  24          HMT41GS6AFR8A-PB  1600
8589934592  Bottom-Slot 2(right)  12          Samsung        24          M471B1G73QH0-YK0  1600
8589934592  Top - Slot 1 (top)    12          Hynix/Hyundai  24          HMT41GS6AFR8A-PB  1600
8589934592  Bottom-Slot 1(left)   12          Samsung        24          M471B1G73QH0-YK0  1600

It's recommended that you get matching RAM modules unless you have a guarantee for compatibility.

Mismatched RAM or RAM that is not on the Qualified Vendor List (QVL) can cause unexpected shutdowns and restarts.

Crucial provides a compatibility guarantee:

Hi there

@Edward

Unless you are running a laboratory full set of VM's or an Internet domain with several hundred logged on users I doubt whether having 48GB RAM on a domestic machine would really buy you anything at all in performance. High memory use on a system BTW doesn't itself mean a shortage of RAM - an OS will use whatever is available -- doesn't always make for faster response or better performance though as any sort of useful tasks will have to fetch data from some sort of (usually Disk bound) data store.

Personally I'd go for the fastest HDD's / SSD's etc I could afford --that will buy performance in spades even on really old machines !!!. If using HDD's get 10,000 RPM ones if you can find them with the largest cache size available -- 7200 RPM models should be minimum spec. Largest possible cache size is important too.

If you really want to go really bonkers and you also have the bank balance of a Lottery Winner !! then how about SAS Fibre link !! for I/O.

Seriously though 95% of the time that I've dealt with poor performance on computers (always assuming enough RAM which your machine clearly has) it's been bottlenecks with the I/O system. You'd be surprised these days at actually how little CPU is used on typical domestic machines -- and on gaming ones most of the "hard stuff" that would normally require CPU power is actually done via separate GPU's.

For those running any sort of Linux / NAS type server simply type the command "top" and you'll be surprised at how little CPU consumption is (type q to exit the display). Windows will have slightly more use due to the much higher overhead of the OS -- I'm assuming your NAS servers don't have or only have a very tiny GUI.

Even running servers you need faster I/O rather than just RAW CPU power -- note I'm talking here of typical HOME type servers --usually things like Linux NAS boxes / spare old computers jigged as a server etc.

Upping 16GB to 32 GB might be reasonable but I've found 16GB more than enough - even when running 4 VM's concurrently and a video / audio multimedia server --fast Disk I/O deals with these perfectly without poor user response times.

here's my CPU use while on a 16GB RAM Intel Celeron processor (dual core) - so not a mega powerful processor. This machine is running a media server currently and has the arch linux OS with the KDE-plasma gui - I'm using firefox to type this post.

Hi thanks for the reply, I did that, now I have 48GB RAM so far the system is stable but the only thing I have found is that rebooting is taking long but I will do a fresh install of Windows 10 and maybe it will get fixed

Thank you all for the replies , first i added my new sticks and remove my other two 8 GB sticks but now i added them back which I have 48 Gb .8 / 16 / 8 / 16. the only issue i have is that rebooting is taking long but the shutdown is fast and boot up the same but I am going to do a fresh install of windows 10 and see if it fixes the issue, if not i will remove my two 8GB rams and stick with my new two 16GB (32GB) RAM.
