I am looking for a gratis Windows 10 app to detect my RAM.

I am a software guy, and not really hardware. I know just about enough to know that I want it all to be DDR2/3/4 as appropriate for my motherboard. I would prefer to have it all from the same manufacturer.

For laptops, I get confused by the L suffix (low voltage?) and whether I must use it exclusively/can mix it with similar which is non-L. I also see some with a U suffix.

I am not asking you to explain it to me. I am one of those people who are happy just to use cotton, I mean RAM, without having to understand how it works.

I am looking for a gratis Windows 10 program which will examine my system and tell me what kind of RAM I need to buy, AND makes sure that I do not buy the wrong stuff.

Then I can look on Amazon or eBay and buy some, although it would be a bonus if the app could find a good deal, based on my country (remembering that we don't all live in the USA)

    I assume that you already did some google like "how to check ram type" or "show ram on windows 10". I found e.g. superuser.com/questions/606318/… and here I saw something about CPU-Z (I used it in the past as well) and "wmic memorychip list full"

  • Yes, I did. But I want an app to do it and make sure that I don't make any mistakes. I did try CPU-Z (+1), but it doesn't give me the manufacturer.

    Not an app either but: wmic MEMORYCHIP get BankLabel,DeviceLocator,Capacity,Speed,Manufacturer will give you the Manufacturer, see also msdn.microsoft.com/en-us/library/windows/desktop/… for some background information.

As I already mentioned in the comments:

Be sure that you always combine memory with the same speed, for other requirements check with your hardware dealer or check https://hardwarerecs.stackexchange.com/

  • The second query gives me Description = Invalid query. The first seems alot more useful, ***but**** as someone harwarephobic, I don;t know what is important and what not I suppose I could just email it all off to some seller & trust them to tell me what I need

IMHO, CPU-Z is a tool that does what you want, even if you have already tried. Maybe you were not too successful, because you looked at the wrong tab.

The type of RAM (like DDR4) is listed in the memory tab.

I am not asking you to explain it to me.

Even if you're not asking, maybe explaining is the key here.

The manufacturer is listed in the SPD tab. Be sure to switch through the different memory slots since a) the tab might be empty in case that slot is empty and b) each module may be from a different manufacturer.

Note that you'll hardly fine the exact same model (same part number) again. But choosing the same manufacturer is probably a good idea.
