Feb 23, 2012 What Nightgloom and Halym said. First user manual and check how slots are described. There you should also have a quick guide on how to plug RAM. General rule: 1. Slots are A1-A2 B1-B2 2. With two same type RAM you plug A1-B1 / A2-B2 slots. The pic Nightgloom provided explains it. For dual channel they should be inserted into matching slots ie slots will usualy be colour coded a and b. If you dont use matching slots then the memory wont run in dual channel, the system will fail to boot or you may experience stability issues. Memory typically cant easily be inserted into their slots the wrong way unless you use a LOT of.
The Lenovo ThinkCentre M720q Tiny is an awesome little desktop PC, designed to be not much larger than an old optical drive yet containing an M.2 PCIe solid-state drive (SSD), 2.5-inch hard drive, and dual SODIMM RAM slots, all upgradeable after purchase. If your model didn't come with enough RAM for the tasks you're running on the M720q, this guide will walk you through the process of adding more.
Hardware to get the job done
- Compatible SODIMM RAM: Crucial DDR4-2666 (From $42 at Amazon)
- Prevent damage: Rosewill anti-static wristband ($7 at Amazon)
- All required tools: ORIA PC toolkit ($33 at Amazon)
- Compact desktop PC: Lenovo ThinkCentre M720q Tiny (From $389 at Lenovo)
How to upgrade RAM in your Lenovo ThinkCentre M720q
Note: Before beginning any upgrades on a PC, it's a good idea to back up your data in the unlikely event something should go wrong. You'll also want to ensure you're not working in a static-filled environment, as it can cause damage to a PC's internal hardware. Consider investing in an anti-static wristband to avoid unnecessary damage.
Lenovo's ThinkCentre M720q Tiny, alongside upgradeable M.2 SSD, and 2.5-inch drive, has two slots for DDR4 SODIMM RAM, accessible through a bottom panel on the PC's chassis. You can configure a model with up to 32GB of RAM straight from the factory, but if you'd like to save some money at checkout or don't initially need quite as much, you can go as low as 4GB from a single stick.
As an upgrade or addition, we recommend Crucial DDR4-2666MHz RAM for its reliability, competitive price, and availability in sizes ranging from 8GB up to 32GB. There should also be no compatibility issues with your system.
Once you have the upgrade RAM ready to go and have made any data backups to safeguard when taking apart the PC, power down the ThinkCentre M720q and clear out a well-lit workspace. It's time to upgrade! Our M720q model came with just one stick of SODIMM RAM, leaving the other slot free, but the steps remain the same for taking apart the PC, removing old RAM, and installing new RAM.
- Unscrew the large black fastener on the back of the ThinkCentre M720q.
- Slide the top and front portions of the chassis cover away from the rear. It should separate with relative ease.
- Turn the M720q over to reveal another removable panel.
- Slide the bottom panel away from the rear of the device. It should come away with relative ease.
- Slide the silver arms off of the first stick of RAM. Upon releasing both clips, the RAM should pop up and remain at an angle.
- Remove the RAM from the slot by carefully pulling it away.
- Insert the new RAM into the slot at about a 45-degree angle. Notice it is keyed and will only fit one way.
- Press down on the RAM until it clicks into place. You should see both silver arms clip back into place to hold the RAM securely.
- Slide the bottom panel back onto the M720q main chassis.
- Slide the top and front panels of the M720q back on the main chassis.
- Screw in the single black fastener on the back of the M720q.
You should now be free to power on your ThinkCentre M720q Tiny to ensure the RAM upgrade went according to plan. You can check to see if it's been recognized by your system with the following steps.
- Right-click the Start button.
- Click System.
You should now be able to see the total amount of installed RAM in the Device specifications section. As long as it matches the total amount you have installed, your upgrade was a success.

Locate memory slots and install memory
DIMM (DRAM, SDRAM, and DDR) memory installation steps
NoteWhen handling memory, hold it by the sides at each end of the module. Be careful not to bend, flex, or drop the memory while handling it. When pushing the memory into the computer, do not apply an excessive amount of pressure. Free progressive slots no download no regi…. Doing so could cause damage to the memory module, as well as the slots on the motherboard. Finally, when installing the memory, distribute the pressure evenly by pressing on both corners of the memory module.

Once the memory is purchased, locate the memory slots on the computer motherboard. If no memory slots are available on the computer, one or more memory modules must be removed before the memory can be installed.
What Slots Should Ram Go In A Car
NoteIf the computer has a small form factor, it may be difficult to access the memory slots. You may have to temporarily remove cables or expansion cards before you can access them easily. When disconnecting anything from the computer, make sure you can remember where each cable and card goes.
Each slot on a motherboard that supports a DIMM is a bank; therefore the computer works if one memory module is purchased.
Examine the memory module before installing it into the computer. At the bottom of the memory module, you should notice one or more notches at the bottom of the card. These notches look like those shown in the picture below.
Make sure that the notches match up with the memory slot you are installing the memory into. These notches allow the memory to be installed only in one direction. If the memory is incompatible, it will not physically match with the slot.
After verifying the notches and direction, the memory needs to be installed, move each memory slot tab out or away from the memory module. These tabs will snap into place as the memory module is installed.
Once these tabs are moved out, gently and firmly push the memory module into the slot. As the memory module is being pushed, the two tabs should snap and hold the memory module into place.
After the memory is installed in the computer, plug the computer back in, and turn it back on. As the computer is booting, the memory should be automatically detected and set up. If you have any difficulties with the memory detected or set up, enter the BIOS setup and verify the memory is correctly detected by the system.
RIMM memory installation steps
What makes RIMM memory modules different from DIMM memory modules is the C-RIMM memory module. This module allows the computer to have a continuous flow of data. When installing a new RIMM, remove the C-RIMM. This module is a small circuit board and has only a few or no chips on it.
When the C-RIMM module is removed, and the two tabs are in the outward position, push the RIMM memory module to a vertical or 90-degree angle. As the memory module is being pushed, the two tabs should snap and hold the memory module into place.
Installing notebook (laptop) memory
Before the memory can be installed into a notebook, the memory slots must be located. If you are unfamiliar with where these slots are located, below is a listing of possible locations:
- On a compartment on the bottom of the laptop.
- Under the keyboard.
- In the computer.
If you cannot locate the slots after looking at each of the above recommendations, we recommend you contact the computer manufacturer for additional help and information.
Once the slots are located, the next step is to install the computer memory. Today, most laptops follow the same memory installation.
Because laptops are thin when compared to a desktop computer, the memory banks are horizontal with the laptop. The memory must be inserted at an angle (approximately 75 degrees). Once it is in the slot, press down on the memory to snap it into place. The memory should also lay horizontally with the computer.
SIMM memory installation steps
30 and 72-pin SIMM memory modules must occupy a bank. Computers that use 72-pin SIMMs have two sockets as one bank. Therefore, two memory modules of equal value must be installed in pairs, unless instructed otherwise by the computer or motherboard manufacturer.
The installation of most SIMM memory is the same. The memory must be entered at an angle, about a 75-degree angle and while still in the memory slot, moved to a vertical or 90-degree angle. As the memory module is moved to a vertical position, it should snap into place. When installed, ensure that both sides of the memory module are snapped into place. If a memory module is not installed properly, it could cause damage to the computer.
We recommend the larger memory modules be installed in the lowest available banks. For example, if the computer has two 4 MB memory modules and you're installing two 32 MB memory modules, place the 32 MB memory modules either in banks 0 and 1, or 1 and 2.
Types Of Ram Slot
NoteSome computer manufacturers may require SIMM modules be installed in a certain order. So, if your new computer memory installation does not work, consider switching the location of the memory.
Set memory in BIOS
Once the memory appears is installed into the computer, test it. Put the case back on the computer. Connect the keyboard, monitor, and power to the computer. Turn on the computer.
TipIs My Ram In The Right Slot
We recommend you do not connect the rest of the cables yet. If you experience problems, you may have to disconnect all the cables again.
As the computer is booting, enter the BIOS and either set the memory to its proper settings or verify that the computer's memory is detected. Once changed or verified, save the settings, exit BIOS and reboot the computer.
For additional help and information, see our BIOS guide.
