Is there a yabs for RAM?

anand_1z

How do I check the frequency of the RAM? Whether the RAM is DDR4 or 5? I tried dmidecode and lshw on my VPS but couldn't find the info I wanted.

Does yabs in some form represent the memory?
Also, is there a need to benchmark RAM separately (to measure the performance of a vps), and if there is what's the standard?

$ cat /proc/meminfo
and
$ sudo dmidecode --type memory | less

Ubuntu

cat /proc/cpuinfo | grep -E "model name|cpu MHz"

In my opinion if you are worried about memory speeds then you are not using a good provider.

Just use a reliable provider and if you see they are using a desktop CPU like Ryzen, make sure to ask if they are using ECC RAM modules. If they are not using ECC RAM modules, well, that will tell you enough about their standards.

No ECC = Don't use that provider for anything production.

This just gives me the CPU MHz.

This gives me "Unknown"/"Not Specified"/"Error Information Handle: Not Provided" for most of the fields.

This is what I found, this is more likely to measure the bandwidth (performance) of the ram, but not frequency

Install sysbench
sudo apt install sysbench

Write speed
sysbench --test=memory --memory-block-size=512K --memory-total-size=10G run

Read speed
sysbench --test=memory --memory-oper=read --memory-block-size=512K --memory-total-size=10G run

It is not possible to reach the hardware level from a VPS to read the DDR type details.

If you want to benchmark it, you can also install mbw and run it giving it a number that is a bit less than half of the free RAM amount you have available. E.g. on a 8 GB lightly-loaded VPS try mbw 3500.

To check the frequency and type of RAM installed on your VPS, use the command:
sudo lshw -class memory
If you can't find the information you're looking for, contact your VPS provider for support. Benchmarking your RAM can be useful but should be done with caution, and there are several tools available for this purpose, such as Memtest86+ and Geekbench. Keep in mind that benchmarks may not always reflect real-world usage, so consider your specific workload and use case when evaluating the performance of your VPS.

Do you think you provide any value by copy-pasting from ChatGPT to a forum?

Oops
Our employee used ChatGPT to find an alternative solution since the topic starter did not mark one from the proposed as suitable; so the suggested option makes value.

Thanks for your help!!!!!!! This equips me with the correct tool to decide which VPS should be idled and which one to let go!!

ramdisk and dd.

Here, I wrote something roughly using mbw to determine the DDR version, but I'm unsure if it works correctly or not.
