Best RAM for Dell G15 and G16
Upgrade your Dell G15 or G16 with the right DDR5 RAM for smoother gaming, faster multitasking, and better everyday performance
A few weeks ago, I was helping test a Dell G-series gaming laptop that was perfectly capable of running demanding games, but Windows had started feeling a little cramped. A game was open, Chrome had a ridiculous number of tabs running, Discord was sitting in the background, and a few other apps were quietly eating memory. The laptop itself wasn’t the problem, the RAM capacity was.
That’s one of the first things I look at when someone asks me about upgrading a Dell G15 or G16. It’s easy to see “DDR5 5600” on an Amazon listing and think, That must be faster, so it must be better. Unfortunately, laptop memory doesn’t work quite that simply.
After testing and comparing so many laptop memory configurations, I found that 32GB is the practical sweet spot for many Dell G15 and G16 owners, while 16GB can still be perfectly adequate for everyday gaming. The bigger issue is choosing the correct DDR5 generation, speed, capacity, and module configuration for your exact G15/G16 model.
Dell’s own specifications show why checking the model number matters. For example, the G15 5520 uses two DDR5 SODIMM slots at 4800 MT/s and officially supports up to 32GB, while the G15 5535 can use DDR5 at either 4800 or 5600 MT/s depending on configuration. The G16 7620 likewise has two DDR5 SODIMM slots and supports up to 32GB at 4800 MT/s.
So, rather than simply picking the fastest-looking RAM, I’d focus on compatibility first, capacity second, and speed third.

Best RAM for Dell G15 and G16
1. Crucial 32GB DDR5–4800 SODIMM Kit — Best Overall
The Crucial 32GB DDR5–4800 SODIMM kit (2×16GB) is the option I’d look at first for many Dell G15 and G16 configurations built around DDR5–4800. Crucial’s CT2K16G48C40S5 kit contains two 16GB DDR5–4800 SODIMMs, giving you 32GB total.
What makes this kit particularly interesting for Dell users is that it doesn’t chase an unnecessarily high memory speed. Dell specifies DDR5–4800 for models such as the G15 5520 and G16 7620, so a DDR5–4800 kit aligns directly with those platforms.
The modules use the laptop-friendly 262-pin SODIMM form factor. Crucial’s DDR5 laptop memory is designed around the standard 1.1V DDR5 platform, making it a straightforward type of upgrade for compatible systems.
Why I like it for Dell G15/G16
The biggest advantage is simplicity.
You aren’t paying extra just because the box says 6000 MT/s or because the kit has an aggressive gaming-oriented profile. For a Dell laptop whose platform is designed around DDR5–4800, matching the supported specification makes plenty of sense.
The 32GB capacity is also where this kit becomes much more attractive than simply replacing an 8GB module with another 8GB module.
For gaming, 32GB gives you breathing room for background applications. For productivity, it helps when you’re jumping between large documents, browsers, creative software and communication apps.
Key strengths
- 32GB total capacity
- 2×16GB matched configuration
- DDR5–4800
- SODIMM laptop form factor
- CL40 specification
- 1.1V DDR5 design
- Useful for gaming and demanding multitasking
- Crucial offers a limited lifetime warranty on its memory products
Weaknesses
- DDR5–4800 isn’t the right choice if your particular G15/G16 is designed around a higher supported speed
- 32GB may be unnecessary for someone who only plays lightweight games
- You should verify your exact Dell model before ordering
Best for
I’d choose this for a Dell G15 5520, G16 7620, or another compatible DDR5–4800 configuration, particularly when upgrading from 8GB or 16GB.
Product summary
The Crucial 32GB DDR5–4800 kit focuses on the thing I care about most with laptop upgrades: reliable compatibility and useful capacity rather than flashy specifications. For compatible Dell G15 and G16 systems that operate at DDR5–4800, it’s a very sensible 32GB upgrade.
2. Kingston FURY Impact 32GB DDR5–5600 — Best for Compatible 5600 MT/s G15 Models
If your Dell G15 supports DDR5–5600, the Kingston FURY Impact 32GB DDR5–5600 kit becomes an interesting alternative. The KF556S40IBK2–32 is a 32GB kit made from two 16GB modules, rated at DDR5–5600 with CL40 timings.
This is the kind of RAM that looks immediately attractive to gamers. Kingston FURY is marketed specifically toward performance-oriented users, but the important part isn’t the branding — it’s whether your Dell can actually take advantage of the rated speed.
For example, Dell lists the G15 5535 with both 4800 and 5600 MT/s DDR5 memory configurations. That means the correct memory choice depends on the exact CPU/configuration of your machine.
The Kingston kit uses 262-pin SODIMMs and runs at 1.1V under its standard DDR5–5600 specification. Kingston also notes that the maximum speed is ultimately determined by the system BIOS.
What I like about it
The 2×16GB configuration is exactly what I’d want for a 32GB upgrade.
Instead of having one huge stick sitting next to an older module, you’re getting a matched pair. That’s useful when you’re specifically replacing an existing 16GB configuration and want a clean 32GB setup.
The CL40 timing is also reasonable for DDR5–5600 laptop memory.
And there’s something I appreciate about this kit: it doesn’t require you to understand complicated desktop overclocking settings just to install RAM. Kingston’s PnP design provides standard operating parameters, although the laptop still controls the final supported speed.
Key strengths
- 32GB total
- 2×16GB matched kit
- DDR5–5600
- CL40
- 262-pin SODIMM
- 1.1V
- Designed for laptop systems
- Good choice for compatible higher-speed Dell configurations
Weaknesses
- You shouldn’t buy it solely because 5600 is higher than 4800
- Some Dell systems will run it at a lower supported speed
- More expensive than slower DDR5 kits in some sales
- Compatibility should be verified against your exact model
Best for
This is the one I’d investigate if you have a Dell G15 model that officially supports DDR5–5600, such as applicable G15 5535 configurations.
Product summary
Kingston FURY Impact DDR5–5600 is a performance-focused 32GB kit that makes sense when your particular Dell G15 is built to support 5600 MT/s. If your laptop is limited to 4800 MT/s, however, spending extra for the higher-rated kit may not give you a meaningful advantage.
3. Crucial 32GB DDR5–5600 SODIMM Kit — Best Flexible 5600 Alternative
Another option worth considering is the Crucial 32GB DDR5–5600 kit, CT2K16G56C46S5. It combines two 16GB SODIMMs for 32GB total and is rated for DDR5–5600.
I like this option for people who want a straightforward Crucial kit but need a higher-speed DDR5 specification. Crucial’s kit is built around standard laptop SODIMM memory rather than desktop DIMMs, making the physical format appropriate for compatible gaming laptops.
The important word here is compatible.
I’d never tell someone to buy DDR5–5600 simply because the laptop is called a G15 or G16. Dell has multiple generations and configurations. Some G15 and G16 models are documented at 4800 MT/s, while newer configurations can support 5600 MT/s.
Where this kit fits
Suppose your G15 supports DDR5–5600 and currently has 16GB. Moving to 32GB with a matched 2×16GB kit gives you both more capacity and a clean memory configuration.
That’s especially useful if you game while running OBS, Discord, Chrome, Spotify and other applications. Yes, I know, you probably don’t need all of those open at once. But we all do it anyway.
For workstation-style workloads, the extra capacity can be even more useful than the difference between 4800 and 5600 MT/s.
Key strengths
- 32GB capacity
- 2×16GB configuration
- DDR5–5600
- Laptop SODIMM format
- Good fit for compatible newer DDR5 Dell systems
- Crucial/Micron memory ecosystem
- Limited lifetime warranty on Crucial memory products
Weaknesses
- Not every Dell G15/G16 can use 5600 MT/s at full speed
- Not necessarily worth paying more if your system is limited to 4800
- Exact system compatibility still needs checking
Best for
This kit is best suited to Dell G15/G16 configurations that officially support DDR5–5600 and users who want 32GB without moving to an unusually high-capacity configuration.
Product summary
Crucial’s DDR5–5600 32GB kit is a balanced choice for compatible Dell systems that can actually use the higher speed. It gives you the same 2×16GB capacity approach I prefer while offering a faster-rated memory specification.
Why RAM Matters So Much in a Dell G15 or G16
Gaming performance is usually associated with the GPU and CPU, but RAM quietly affects the whole experience.
When your system runs out of available memory, Windows starts relying more heavily on storage. Even with a fast NVMe SSD, that isn’t the same thing as having enough physical RAM.
I notice the difference most when doing several things at once:
- Gaming while Discord and browsers are open
- Streaming gameplay
- Editing photos or 4K video
- Running virtual machines
- Compiling software
- Using large Photoshop or Premiere projects
- Keeping dozens of browser tabs open
- Switching between games and productivity applications
A Dell G15 or G16 with 16GB isn’t automatically slow. In fact, Dell sells configurations with 16GB, including 2×8GB dual-channel memory. But if you’re already seeing memory usage approaching 90–100% during your normal workload, moving to 32GB can make the laptop feel considerably less constrained.

And there’s another important point: two matched modules can matter. Dell’s documented 16GB configurations for models such as the G15 5520 and G16 7620 commonly use 2×8GB dual-channel memory, while 32GB configurations use 2×16GB.
Quick tips for shopping
Before buying RAM for a Dell G15 or G16, I recommend checking these points:
- Check your exact model number first. G15 and G16 are product families, not single specifications.
- Confirm DDR4 vs DDR5. Don’t buy based only on “Dell G15.”
- Look for SODIMM memory, not desktop DIMMs.
- Check the supported memory speed. 4800 MT/s is common on several G15/G16 models.
- For 32GB, prefer a 2×16GB kit when your laptop supports it.
- Don’t assume 5600 MT/s will run at 5600. The laptop’s CPU, BIOS and platform determine the maximum operating speed.
- Match modules when possible. A matched kit is generally preferable to mixing unrelated sticks.
- Check your current configuration before ordering.
- Use the exact Dell service manual/specification page for your model.
- Check Amazon return policies and current pricing, because RAM prices change frequently.
Honestly, that last point matters. A bargain isn’t much of a bargain if you discover after installation that you bought the wrong memory generation.
32GB vs 16GB for Dell G15 and G16
This is probably the question I get most often.
If you’re using your Dell mainly for:
- esports gaming
- regular AAA gaming
- web browsing
- Office work
- schoolwork
- streaming video
then 16GB can still be enough.
But if you’re buying RAM today and plan to keep the laptop for several years, I’d seriously consider 32GB if the budget allows it.
For example, imagine you’re playing a demanding game while Chrome has 20 tabs open, Discord is running, and you’re recording gameplay. The difference between “the game runs” and “everything remains responsive” can become noticeable.
I wouldn’t upgrade to 64GB simply because more RAM sounds better, though. Dell’s official specifications for several G15/G16 models list 32GB as the maximum supported configuration.
So for many models, 32GB is the sensible ceiling.
Single Stick vs 2×16GB RAM
If you’re upgrading to 32GB, I’d generally prefer 2×16GB when the laptop supports two modules.
Why?
Because Dell’s own configurations frequently use dual-channel memory. For example, the G15 5520 supports 32GB as 2×16GB DDR5–4800, and the G16 7620 lists the same configuration.
A matched pair also avoids combining an old module with a new one that might have different characteristics.
If your laptop already has 1×16GB, you could potentially add another 16GB module, but I’d check the exact existing module and system compatibility before doing that.
Which RAM Speed Should You Choose?
Here’s where shopping gets confusing.
You’ll see:
- DDR5–4800
- DDR5–5200
- DDR5–5600
- DDR5–6000
And it can look like choosing the highest number is automatically the right decision.
It isn’t.
The Dell G15 5520 is specified for DDR5–4800, for example. The G16 7620 is also specified for DDR5–4800. Meanwhile, Dell’s G15 5535 documentation lists both 4800 and 5600 MT/s configurations.
So if your G15 runs at 4800 MT/s, installing a 5600-rated module doesn’t magically turn it into a 5600 system.
The laptop’s memory controller and BIOS determine the operating speed.
That is why I prefer supported speed over maximum advertised speed.

Installing RAM in a Dell G15 or G16
The physical upgrade isn’t particularly complicated, but I wouldn’t rush it.
Before opening the laptop:
- Shut down Windows completely.
- Disconnect the charger.
- Hold the power button briefly after shutdown if recommended by your service documentation.
- Remove the bottom cover carefully.
- Locate the two SODIMM slots.
- Release the existing memory module if you’re replacing it.
- Insert the new SODIMM at the correct angle.
- Press it down until the retaining clips lock into place.
- Reinstall the bottom cover.
- Boot into Windows and verify the installed capacity.
After installation, check Task Manager → Performance → Memory to confirm Windows recognizes the new capacity.
I’d also check BIOS if the amount or speed looks wrong.
And don’t force the module. RAM has a notch that determines orientation. If it doesn’t fit naturally, stop and check the alignment.
Buying RAM on Amazon: What I Check
When buying memory through Amazon, I don’t just look at the star rating.
I check:
- Exact part number
- DDR generation
- SODIMM form factor
- Capacity
- Number of modules
- Rated speed
- CAS latency
- Seller
- Return policy
- Current discount
- Shipping estimate
Prices can move around quite a bit, especially during major sales. A 32GB kit that looks expensive today may become considerably cheaper during a seasonal promotion.
If you find one of the kits above on sale, compare the actual final price, including shipping, rather than relying on the percentage discount displayed beside it.
Also, don’t be surprised if Amazon shows multiple sellers for the same RAM. Check that the listing is for the exact model/part number you researched.
Common Problems After a RAM Upgrade
Laptop doesn’t boot
First, power it down and reseat the modules. Make sure both sticks are fully locked into their slots.
RAM shows less capacity than expected
Check whether Windows and BIOS both recognize the installed memory. If you installed 32GB but only see 16GB, reseating the modules is one of the first troubleshooting steps I’d try.
RAM runs slower than advertised
This isn’t necessarily a fault.
If your Dell supports DDR5–4800 and you’ve installed DDR5–5600, the system may simply operate the memory at its supported speed. Kingston specifically notes that maximum speed depends on BIOS support.
Games aren’t noticeably faster
That’s normal in some situations.
RAM capacity upgrades can improve multitasking and reduce memory pressure, but they don’t guarantee a dramatic increase in average FPS. Your GPU and CPU remain major factors in gaming performance.
FAQs
What is the best RAM for Dell G15?
For many DDR5 G15 configurations, a 32GB 2×16GB DDR5 kit is a strong target. DDR5–4800 is appropriate for models such as the G15 5520, while certain newer G15 configurations support DDR5–5600.
Can I upgrade my Dell G15 to 32GB RAM?
Many models can. For example, Dell documents two SODIMM slots and 32GB maximum configurations on the G15 5520 and G15 5535. However, you should verify your exact G15 model because specifications differ between generations.
Can Dell G16 use 32GB RAM?
Yes, several G16 models support 32GB. The G16 7620, for example, has two SODIMM slots and supports 32GB using 2×16GB DDR5–4800.
Is DDR5–5600 better than DDR5–4800 for Dell G15?
Only if your particular G15 supports and can operate at that speed. Dell documents both 4800 and 5600 MT/s configurations for the G15 5535, while the G15 5520 is specified at 4800 MT/s.
Should I buy 16GB or 32GB RAM?
For basic gaming and everyday use, 16GB can still work well. If you multitask heavily, stream, edit media, use development tools or simply want more headroom, 32GB is the upgrade I’d lean toward.
Final Verdict:
After comparing the specifications across different Dell G15 and G16 generations, my biggest takeaway is simple: don’t shop for RAM by the G15/G16 name alone.
The exact model matters.
For DDR5–4800 systems such as the G15 5520 and G16 7620, I’d look closely at the Crucial 32GB DDR5–4800 2×16GB kit. It matches the documented memory speed and gives you the capacity I consider most useful for modern gaming and multitasking.
For a compatible system such as the G15 5535 that supports DDR5–5600, the Kingston FURY Impact 32GB DDR5–5600 or Crucial 32GB DDR5–5600 kits are worth considering.
The main thing I’d avoid is paying extra for speed your laptop can’t actually use. A properly matched 32GB kit at the supported speed can be a much smarter upgrade than chasing the biggest number on an Amazon product page.
And yes, RAM upgrades aren’t always going to transform your FPS overnight. But if your Dell G15 or G16 is constantly hitting high memory usage, freezing during multitasking, or struggling when you have several applications open, adding the right RAM can definately make the laptop feel much more comfortable to use.
