Ever been in a situation when you are in the final circle of a battle royale, and your team is counting on you, but suddenly, your game freezes? That’s the issue many gamers face.
While a graphics card can be the issue, most of the time, the real issue is the lack of memory. When your PC runs out of available RAM, it struggles to keep up with modern games and background tasks.
Fortunately, upgrading your RAM is one of the simplest and most affordable PC upgrades you can make. However, there are some technicalities in this process.
In this guide, I have mentioned the complete steps you need to follow when upgrading the RAM for your PC to avoid any unnecessary challenges.
What You Need to Upgrade RAM for Gaming?
Tools:
- Phillips #1 screwdriver (to open your case)
- Anti-static wrist strap (or just touch the metal frame of your case regularly)
Software (free):
- CPU-Z or HWiNFO64 — to read your current RAM specs
- Windows Task Manager — to verify after install
Parts:
- A compatible RAM kit (more on choosing below)
Cost estimate: $30–$120 depending on capacity and speed
How to Upgrade RAM for Gaming on PC?
The following are the steps you should follow to upgrade RAM for gaming on PC.
Step 1: Check Compatibility Before You Upgrade RAM for Gaming
Don’t buy anything yet. Open CPU-Z (free at cpuid.com), go to the Memory tab, and note:
- RAM type (DDR4 or DDR5)
- Current speed (e.g., 3200 MHz)
- How many slots are occupied
Then go to the Mainboard tab, grab your motherboard model, and look up its spec page. You need to know the maximum supported capacity and speed, plus how many DIMM slots you have (usually 2 or 4).
Skipping this step is how people end up buying DDR5 for a DDR4 board. If you’re not sure what your system supports, my guide on choosing PC parts takes you through compatibility in plain terms.
Step 2: Choose the Right RAM
Match the type your board supports. DDR4 and DDR5 are physically incompatible, and the notch position is different, so you can’t force the wrong one in.
For 2026 gaming:
- 16GB DDR4 @ 3600 MHz: solid minimum for most titles
- 32GB DDR5 @ 6000 MHz: the current sweet spot for modern open-world games and multitasking
- 64GB is overkill for gaming alone
Speed matters, but not as much as marketing implies. DDR5-6000 and DDR5-6400 perform nearly identically in games. Prioritize capacity first.
Not sure whether DDR4 or DDR5 makes more sense for your specific build? This DDR4 vs DDR5 for Gaming breakdown covers real benchmark differences across game types.
Always buy in matched pairs, such as 2×8GB or 2×16GB. Dual-channel mode is noticeably faster than a single stick of the same total size.
Step 3: Power Down and Ground Yourself
Shut your PC down completely instead of putting it on sleep or hibernate. Unplug the power cable from the back of the case. Press the power button once to drain residual charge from the capacitors.
Touch the metal frame of the case before handling any components. If you have a wrist strap, clip it to the case. Static discharge is invisible and kills hardware silently — this 10-second step is always worth it.
Work on a hard, flat, non-carpeted surface.
Step 4: Remove Your Old RAM (If Replacing)
Open your side panel. Usually two thumbscrews on the back-left. The RAM slots are the long, narrow slots sitting right next to the CPU cooler.
To remove existing sticks, press the retention clips at one or both ends (the mechanism varies by board). The stick will pop up slightly. Pull it straight out because no twisting or angling is needed.
If you’re adding a second kit to empty slots, skip this step.
Step 5: Seat the New RAM
Check your motherboard manual for the correct slot order. On a 4-slot board, install in slots A2 and B2 (the second and fourth slots, counting from the CPU). This is the dual-channel configuration on most boards. Installing in A1 and B1 instead is a common mistake that still works but may reduce stability headroom.
Align the notch on the stick with the key in the slot. It only fits one way. Place both thumbs on the ends of the stick and press down with firm, even pressure until you hear and feel a distinct click. The retention clips should snap back up on their own.
If it’s not clicking, push harder. Under-seated RAM is the #1 cause of failed boots after an upgrade.
Step 6: Boot and Verify
Plug everything back in and power on. Your PC may restart once automatically while it detects new hardware. That’s normal.
- Once in Windows: open Task Manager → Performance → Memory. You should see the correct total (e.g., 32.0 GB available).
You should also check the reported speed. If it shows less than your kit’s rated speed, go into BIOS and enable XMP (Intel boards) or EXPO (AMD boards). Most motherboards don’t activate this automatically. It’s usually a single toggle under the AI Tweaker or OC menu. Save and reboot.
How to Troubleshoot Your PC After You Upgrade RAM for Gaming?
- PC won’t POST after install: RAM isn’t fully seated. Power off completely, unplug, re-seat both sticks with firm pressure until you hear the click on both ends. This fixes it 90% of the time.
- Windows only shows half the RAM: Either one stick isn’t making contact, or you’ve installed both in the same channel (e.g., A1 and A2). Check your manual for the correct dual-channel slots.
- Speed is lower than what the kit is rated for: XMP/EXPO isn’t enabled. Enter BIOS on the next boot, enable it, save and exit.
- System beeps repeatedly and doesn’t boot: One stick may be faulty or incompatible. Remove one, test. Then swap. If one stick works and the other doesn’t, the failing one is either dead or doesn’t meet your board’s supported spec list.
- RAM physically won’t fit: You bought the wrong generation. DDR4 and DDR5 won’t swap places — the notch is in a different position by design. Return it and match to what your board supports.
Final Words on How To Upgrade RAM For Gaming
You’ve done it by following the steps such as checking compatibility, installing new RAM, enabling XMP, and system verification. This is one of the fastest ways to get a real performance return from your gaming PC, and you did it without touching a single cable or worrying about driver installs.
If you want to take things further, building a computer from scratch is the natural option. It covers every component from the ground up, so you understand exactly what everything does and how to build your next machine the right way.
And if you’ve upgraded RAM and your system still isn’t where you need it, you should buy a new PC, as it will help you honestly.

16GB is the practical floor. Titles like Hogwarts Legacy and Alan Wake 2 regularly push past 12GB. 32GB gives you headroom for multitasking, streaming, and future-proofing. 64GB is only useful for content creation or heavy workstation use.
You can, but you shouldn’t. Mixed kits default to the slower speed and can trigger instability under load. Always buy a matched kit from the same manufacturer and part number.
No. Windows detects the new RAM automatically on boot. No OS reinstall, no driver updates needed.
If you’re running below 16GB, then yes, especially in open-world games. If you’re already at 16GB, the improvement shows up as reduced stuttering and smoother 1% lows rather than a big average FPS jump.
Sometimes. Many modern laptops have RAM soldered directly to the board, making it non-upgradeable. Before buying anything, look up your specific laptop model’s service manual and check for user-accessible SODIMM slots.
