Optimise RAM Performance During Loadshedding — Guide

The lights go out. Again. You sigh, wait for the inverter to kick in, and reboot your PC. But instead of jumping back into your game, you’re stuck watching Windows slowly crawl back to life. Sound familiar? Loadshedding is tough on our hardware, and your PC’s memory (RAM) often takes the biggest hit during these abrupt shutdowns. Learning to optimise RAM performance during loadshedding isn’t just a tech tip… it’s a survival strategy for South African gamers.

Why Loadshedding Puts a Strain on Your RAM

Every time your PC shuts down unexpectedly, everything stored in your Random Access Memory is instantly wiped. This includes your open applications, game data, and even parts of the operating system that were cached for quick access.

When you reboot, your system has to reload all of this from your much slower SSD or hard drive. This is why your PC feels so sluggish after a power cut. If your RAM was already nearly full before the outage, the recovery process is even more painful. Your PC has to work overtime using virtual memory (a slow "overflow" space on your main drive), causing that frustrating lag. Effective RAM optimisation for loadshedding is about minimising this recovery time. 🔧

Taming Your PC Before the Power Dips

You can’t predict every outage, but you can prepare your system to handle them better. A few simple tweaks can make a massive difference in how quickly you get back up and running.

  • Trim Startup Programs: How many apps launch the moment you log into Windows? Each one eats up precious RAM. Press Ctrl + Shift + Esc to open Task Manager, go to the "Startup" tab, and disable anything non-essential. Your future self will thank you.
  • Browser Tab Discipline: We're all guilty of it. Twenty-plus tabs open in Chrome is a massive memory drain. Use bookmarks or a session manager extension to save tabs for later, and try to keep only what you currently need open.
  • Close Background Apps: Before a long gaming session, close unnecessary background apps like Discord, Spotify, or creative software if you're not actively using them. This frees up RAM for what matters most… your game.
TIP FOR YOU

Quick RAM Check ⚡

Wondering how much RAM you're actually using? Open the Task Manager (Ctrl + Shift + Esc), click on the "Performance" tab, and then select "Memory". This gives you a real-time look at your usage. If it's consistently above 80-90% during normal use, it might be time for an upgrade!

Can a RAM Upgrade Help With Loadshedding Recovery?

Absolutely. While software tweaks help, hardware is the foundation. Having enough physical RAM means your PC relies less on that slow virtual memory, both during normal use and especially during a post-loadshedding reboot.

If your system is still running on an older standard, upgrading your PC's memory modules can provide a significant boost. For most gamers in South Africa today, 16GB of quality DDR4 Memory is the sweet spot for performance and value. It ensures smooth multitasking and faster loading times.

For those building a new rig or wanting to future-proof their setup, jumping to the latest DDR5 Memory offers even higher speeds and better efficiency. 🚀 When choosing, reliability is key. Brands like Kingston have a long-standing reputation for solid performance, while options from ADATA often provide an excellent balance of speed and affordability. Ultimately, a good RAM kit is a crucial part of any strategy to optimise PC performance during loadshedding.

Ready to Banish Loadshedding Lag? While we can't stop the power cuts, you can control how quickly your PC recovers. A solid RAM upgrade is one of the most effective ways to ensure a smooth, fast restart every time. Explore our wide range of high-performance RAM and get back in the game faster.

Close nonessential apps, disable background services, and use lightweight browsers to reduce RAM usage on UPS power and minimise swap writes.

Choose hibernate to save RAM state to disk for long outages; use sleep for short UPS-backed interruptions to resume faster.

Increase RAM cache limits, raise swappiness on Linux or adjust pagefile settings on Windows to prevent memory swapping during loadshedding.

Enable power saver profiles, limit startup apps, and set a smaller pagefile or fixed pagefile size to optimise RAM on battery.

Yes — tweak vm.swappiness, adjust cache pressure and use zram to improve RAM performance on UPS-protected Linux systems.

Adding physical RAM reduces swapping and keeps apps responsive during power cuts, lowering disk I/O while on UPS power.

Set a fixed pagefile size, move it to a fast SSD if available, and reduce reliance on pagefile to stabilise performance on UPS.
