I'm having a hard time figuring out whether or not a certain laptop/computer's RAM can be upgraded or not.  Is there a rule of thumb that determines how much max RAM one could add to a system without looking it up via external websites?   A little bit of a background information: I work in computer sales at a computer electronics store, so it is virtually impossible for me to install any sort of software that would detect computer specs, and I get a lot of customers who wonder what laptop/desktop RAM upgrades usually are.  It's frustratingly annoying to have to constantly search the web for information.  Is there a certain rule that adding more RAM entails? Does it make a difference if it's a 32-bit or 64-bit machine? Are other factors, such as the OS, hardware, and other things matter?

I want to find out the exact model of my computer's motherboard so that I can see what sort of memory chip, graphics cards and other components it supports.  I'm using Windows 7 Ultimate 64-bit.

I currently have a  8GB DDR4 RAM. I want to upgrade my system to have 16 GB RAM. I already have bought the  8GB DDR4 RAM.  I understand that my current RAM is a single-rank RAM and my new one is dual-ranked RAM. My question is can I plugin the new RAM into my MOBO and expect everything to work harmoniously?  My MOBO is a MSI Gaming Z170A M5.

If I want to add more RAM to my computer, how can I buy something compatible? What kinds are there? How do I determine which kind my computer will accept and how much I can add?

So I have a  which I need to buy RAM for.  Now the specs say that it supports DDR3-L.  I am thinking of getting the following kit:  CORSAIR Vengeance (2x8) 16GB 204-Pin SO-DIMM Model CMSX16GX3M2B1600C9 DDR3 1600 (PC3 12800) Cas Latency 9 1.35V (also supports operation at 1.5V) Dual Channel Kit Timing: 9-9-9-24   My question is whether this will work for a slot that is specified as DDR3 L?

I want use 4GB of RAM.  Can I use in Windows XP 32-bit?  Or should I go for Windows XP - 64-bit? Does it support 4GB of RAM?  Does Windows 7 32-bit support more than 4GB of RAM, or is >4GB support only available in Windows 7 64-bit?

Due to space constraints, I need to purchase a laptop to replace my desktop computer. However I don't know whether I need a laptop with 8GB or 16GB of RAM. My desktop currently has 16GB.  What is the easiest way to run something in the background to determine my typical RAM usage over a period of, say, a month? My goal is to have enough data to base my RAM purchase on real-world usage of my desktop.  I've seen a few articles describing how to use Performance Monitor to do this, but they all seem to suggest different things to monitor. Several of them also talk about measuring my swap, which I don't believe I should be interested in.

I have two RAM sticks: one 533 MHz and one 667 MHz. Is it safe to use both of these in the same system?

I have a question regarding my laptop's RAM.  I have 2 slots. One is empty; the other one has a Samsung SODIMM 204-pin 2GB DDR3 1333MHz SDRAM CL9, non-ECC, unbuffered module, running at 1066 (!) MHz, because the motherboard supports this maximum frequency, and in single channel mode.  Is it OK for me to add, in the empty slot, a Samsung SODIMM 204-pin 2GB DDR3 1066 MHz SDRAM CL8 (!), non-ECC, unbuffered RAM module?  Will they work fine with both running at 1066 MHz?  And will it be activated in dual channel mode in this case?    Well, the different apps show me that the RAM module is running at 1066 MHz, the guide for my laptop says it supports 1066 MHz DDR3 Dual Channel. And also they show me that it runs in single channel mode. Tried to see the tech specs on an almost similar laptop, with 2 modules identical to this one, they run both at 1066 MHz (even if they are 1333 MHz both), and the Dual Channel mode is activated (Dual Channel Ungaged, supose it's ok).

The specifications of my system say it supports 400 MHz and 533 MHz DDR2 unbuffered SDRAM. I have a 1 GB DDR2 PC2-5300 laptop RAM module. Can I use this in my desktop? If not, what exactly is the difference between desktop RAM and laptop RAM?

I recently installed 8GB of RAM onto a quad core workstation (HP xw8600) running Windows XP Pro (32-bit).  I added the /PAE switch in the boot.ini file, but the SysInfo is saying 3GB total memory still.  Is Windows recognizing the extra memory?  Is there a way to tell?  Any help is appreciated.  Thanks.

I have a mid-2011 iMac which came with 4GB RAM (2x2GB). I just bought 8 GB (2x4GB) and added it to get a total of 12GB. The current configuration is as follows:    Given that the RAM is a different size, do I have the optimal locations for the different RAM chips? At the moment what I did was to simply add the 2 new sticks of RAM in the two empty slots.

If a motherboard's specifications say it supports DDR3 SDRAM sticks, would I be correct to assume it is also compatible with DDR2 RAM? Am I wrong, or does it depend on the motherboard?

My girlfriend bought a laptop last week. It's a core 2 duo with 4 GB  We installed vista 64bit, and one of the first things we did was right click on "My computer" to see gthe properties. Immediately we noticed something strange about her RAM, the line said: Installed memory (RAM): 4,00 GB (3,68 GB usable)  I told her not to worry, thinking it must be something about the laptop hardware (considering her vista installation came from the same DVD as mine, and I never noticed anything like that on my 4 GB desktop). One hour ago, it got worse. We looked at Properties again, and it now says: Installed memory (RAM): 4,00 GB (2,98 GB usable)  What does that mean? Are those 1,02 GB missing or being used by the system?  EDIT: There is a possibility that the sytem information is wrong. I just noticed that it reports an intel T6500 processor, when it's actually a T6400.  How can I find out how much RAM is really available to the system?  EDIT2: Checking the resource monitors, it says 1003 MB are reserved for the hardware. Is that good or bad? Thanks

Is DDR3L RAM and DDR3 RAM compatible?  I have a Notebook that I want to upgrade, Toshiba Satellite C55-B5212KL and () where they clearly state that the RAM is a DDR3L.  Now my question comes from the fact that I have dual OS (Windows 8.1 and Linux Mint 17.3) and the outcomes after using an app on Windows and running two commands in Linux are like this:  Outcome of memory under Windows 8.1    Outcome of SPD under Windows 8.1    Linux: sudo lshw    Linux: sudo dmidecode --type 17    On Linux the results are straightforward and they don’t show that my laptop has a DDR3L memory, they say it has a DDR3 @1333 MHz. On the other hand the app in Windos 8.1 also shows a RAM DDR3 but @666 MHz which is confusing for me since I don’t know so much about hardware.  So again, whom should I trust for upgrading my laptop and making the right purchase, my output from two different OS or the manufacturer specs?

I have a HP pavilion g6 1301tx laptop. It came up with 2GB of DDR3 ram, windows 7 pro (64 bit), 1 GB ATI graphic card and motherboard - hp 1670 serial number- pcela212c1bo7I. Few months back I installed Windows 10 (32 bit) . Now I want to increase ram by 2 GB , total of 4 GB so I installed a 2 GB DDR3 ram to the other slot and  checked system properties of my computer it says 2.5 GB usable out of 4 GB, now I don't understand why rest of the 1.5 GB is not usable what should i do to get 4 GB ram?

I have an Asus G50vt-x5 laptop with 4GB of RAM installed. But Ubuntu 10.10 shows only 3GB of RAM. Why is it only showing 3GB of RAM instead of the full 4GB? output of free command is :  neal@ubuntu:~$ free              total       used       free     shared    buffers     cached Mem:       3095668    2972784     122884          0     747996    1590044 -/+ buffers/cache:     634744    2460924 Swap:            0          0          0
