Clearing RAM in Windows usually means finding the app, service, browser tab, or startup item that is holding memory longer than it should. It is not magic, and you do not need a sketchy optimizer. If you are deciding whether memory capacity is the real issue, our guides to 32GB RAM kits and RAM for gaming and editing give useful upgrade context.
What you’ll need
You need Task Manager, Settings, a restart window, and a few minutes to watch which processes climb after boot. A hardware upgrade only makes sense if your normal workload keeps filling memory after cleanup.
Pros
- DDR4-3600 XMP at 1.35V is the Ryzen AM4 sweet spot, aligning FCLK 1:1 at 1800MHz for best latency.
- Matched 2x16GB kit is factory-tested as a pair, reducing dual-channel instability compared to mixing sticks.
- Compatible with both Intel XMP and AMD DOCP/A-XMP BIOS profiles without manual sub-timing adjustments.
- Ships with JEDEC SPD fallback so the system always boots safe at default clocks before XMP is enabled.
Cons
- CL18 primary latency is mid-range; DDR4-3600 CL16 kits exist for buyers prioritizing tighter timings.
- No ECC support, so workstation or Threadripper ECC builds need a different kit entirely.
The G.SKILL RipjawsV F4-3600C18D-32GVK is a mid-range DDR4 desktop kit targeting Intel and AMD mainstream platform builders who want 32GB capacity at DDR4-3600 without overpaying for CL14 or CL16 enthusiast kits. It ships as a matched 2x16GB dual-channel pair in the standard 288-pin U-DIMM form factor.
The defining spec here is the XMP profile: DDR4-3600 at CL18-22-22-42, 1.35V. On AMD AM4 Ryzen systems, 3600MHz is the well-documented sweet spot for achieving a 1:1 FCLK ratio at 1800MHz, which keeps infinity fabric latency in check and translates to measurable gains in lightly-threaded workloads and gaming frame times compared to DDR4-3200 or lower.
CL18 is a genuine trade-off at this speed. Competing DDR4-3600 kits with CL16 or CL14 exist and offer lower absolute latency, though they typically carry a price premium. Owners report stable XMP operation across a wide range of B450, X570, and Z490/Z590 boards, but reaching rated speed on some budget AM4 boards may require manual sub-timing adjustments or AGESA microcode updates.
Buy this if you are building or upgrading an AM4 Ryzen or Intel LGA1700 desktop and want reliable 32GB DDR4-3600 dual-channel performance without tuning. Skip this if you need CL16 or tighter for competitive latency, or if your board has a limited QVL and you have not verified compatibility via G.SKILL's configurator tool first.
Platform Support: This kit uses 288-pin DDR4 U-DIMM and is compatible with Intel LGA1700 (Z690/Z790) and AMD AM4 (B450/X470/B550/X570) platforms. AM5 uses DDR5 exclusively, so this kit is not compatible with Ryzen 7000/9000 series builds on AM5 boards.
XMP and DOCP Activation: Rated speed of DDR4-3600 CL18-22-22-42 at 1.35V requires enabling XMP (Intel) or DOCP/A-XMP (AMD) in BIOS. Default JEDEC SPD boots at DDR4-2133 or DDR4-2400. On AM4, DDR4-3600 aligns FCLK at 1800MHz for a 1:1 ratio, which is the recommended operating point for Ryzen 3000 and 5000 series CPUs.
Slot Population and Mixing: Install both sticks in the recommended dual-channel slots per your motherboard manual, typically A2 and B2 in a 4-slot board. G.SKILL explicitly warns against mixing this kit with other modules; doing so voids the matched-pair guarantee and risks instability at XMP speeds.
Cooler Clearance: Exact heatspreader height is not specified in the source data, but RipjawsV modules are noted for a lower profile than Trident Z or RGB variants, reducing conflicts with wide tower coolers. Verify clearance if using a low-clearance cooler on a tight ITX board.
Step 1: restart before changing anything
Restart first, not shutdown. Fast Startup can preserve parts of the session, while restart gives Windows a cleaner memory state. After reboot, wait 2 minutes before judging usage because launch services need time to settle.
Open Task Manager with Ctrl+Shift+Esc, choose Processes, and sort by Memory. Write down the top five items. Simple list. It keeps you from chasing the wrong app later.
Step 2: close heavy apps the right way
Close browsers, game launchers, editors, and sync tools from their own menus, then confirm they vanished from Task Manager. Some apps minimize to the tray, so check the arrow near the clock too.
If a browser is the culprit, use its built-in task manager or tab memory view. One bad extension can use more RAM than ten normal tabs, and you will not spot it by staring at the Windows desktop.
Step 3: disable unnecessary startup items
In Task Manager, open Startup apps and disable launchers you do not need on every boot. Keep audio drivers, GPU tools you rely on, cloud backup if you use it, and security tools. Remove the vanity stuff.
Reboot again and compare idle memory after 2 minutes. If the number drops and stays lower, you fixed the easy part. If it climbs back, continue.
Step 4: find background services and memory leaks
Open Settings, Apps, Startup, then check installed apps you barely use. Uninstall old RGB suites, duplicate updater tools, trial VPNs, and abandoned printer software. They are common background hogs.
If one app grows nonstop during normal use, update it or reinstall it. Do not clear RAM every hour to hide a leak. Fix the cause or choose lighter software.
Step 5: decide if you need more physical memory
Use Performance, Memory in Task Manager. If committed memory repeatedly approaches the installed capacity during normal work, cleanup will only help a little. The G.SKILL Ripjaws V kit listed here is DDR4, 32GB as 2x16GB, 3600MT/s, CL18-22-22-42 at 1.35V, with XMP support for Intel and AMD desktops. It costs $219.99 and has a 4.1 rating.
Check your motherboard memory type before buying. DDR4 and DDR5 are not cross-compatible, and laptop SO-DIMM slots differ from desktop U-DIMM slots. Don’t guess.
Troubleshooting common issues
Memory usage is high right after boot
Wait a few minutes. Windows Search indexing, updates, cloud sync, and game launchers often settle after startup.
Task Manager shows cached memory
Cached RAM is not automatically bad. Windows uses spare memory to speed up reads and releases it when apps need more.
A game stutters after clearing apps
Check VRAM, shader compilation, and storage activity too. RAM is only one possible bottleneck.
The PC crashes after adding RAM
Disable XMP, boot at default speed, then update BIOS and re-enable a supported profile.
Before and after expected outcomes
A good cleanup should make the system feel less sticky when switching apps, reduce paging to disk, and lower idle memory. It will not turn 8GB into 32GB, and it will not fix a slow CPU.
Variations and advanced setups
Power users can use Resource Monitor, RAMMap, and Event Viewer to chase deeper issues, but most Windows users get the win from restart behavior, startup cleanup, and removing the one app that never lets go.
One more thing to keep in mind with how to clear ram in windows: a clean buying decision starts with the symptom, not the product page. Write down what is wrong in plain language, then match that sentence against the title specs. If the item does not answer that sentence, it is probably noise. That sounds basic, but it prevents expensive mismatches.
We also weighed price against category fit. A product can have a strong rating and still be the wrong answer for how to clear ram in windows. The opposite is true too: a modest, specific part can be the smarter buy if it fixes the actual bottleneck. Do not let a polished title do the thinking for you.
Compatibility is the other quiet trap. Desktop parts, laptop parts, docks, cases, coolers, headsets, storage devices, and power supplies each have physical limits. Ports, dimensions, wattage, socket support, memory type, wireless mode, and cable standards matter. Check twice. Buy once.
For a home PC, the best upgrade is usually the one you can explain in one sentence. More stable power. Lower idle heat. Less memory pressure. Better headset mic behavior. Faster storage for the workload. Cleaner case airflow. If you cannot name the benefit, wait.
Ratings help, but they are not a substitute for the missing review counts in this batch. We used the ratings provided, then leaned harder on concrete title details such as capacity, speed, port type, form factor, price, wireless mode, dimensions, and included features. That keeps the recommendation grounded.
Finally, consider the return path. PC hardware compatibility can surprise even careful buyers, especially with older motherboards, compact cases, proprietary prebuilt layouts, and mixed USB or display standards. Keep packaging until the part is installed, configured, and stable through normal daily use.

Common questions
Do RAM cleaner apps help?
Usually no. They often force Windows to dump useful cache, then the system rebuilds it moments later.
Is 16GB still enough?
It can be for office work and light gaming, but multitasking, editing, and heavy browsers are more comfortable with 32GB.
Will more RAM raise FPS?
Only if you were memory-limited. Otherwise CPU and GPU limits dominate.
Should I clear RAM before gaming?
Close heavy apps and launchers you do not need, then play. You do not need a ritual.
