Laptop experiences high memory consumption during gameplay on a Predator G9-593.
Hey there, I’m trying to clarify what’s been happening with my setup. It’s been challenging over the past year. I use a Predator G9-593 laptop—one of those high-performance gaming machines—with all standard settings. It’s been running for about seven years now and has suffered from overheating until I cleaned everything off.
The problem is, I’m getting BSoDs while playing games like The Sims 4 (the reason isn’t clear), and there are Video_TDR errors with WhoCrashed pointing to Nvidia or DirectX drivers. I’ve updated the drivers and reinstalled them, but it doesn’t help. The system freezes randomly and then restarts.
I checked RAM usage and found that under normal load, 6GB is used with only 4GB in cache, leaving around 26GB free. But when the game starts, it jumps to about 15.5 or 16GB of usage, with nearly the same cache size, leaving just a few hundred MB available. Running the game with many mods (especially clothing) makes it very demanding. I’m puzzled by the 16GB cache—could SuperFetch be using that? Would enabling it help? Or is it the game itself leaking memory?
Upgrading to 32GB RAM seems to ease things a bit, but it never goes above 16GB in use. Maybe there’s something wrong with the settings? Honestly, I’m leaning toward replacing this laptop, especially for gaming, and might consider a new desktop instead. The GPU could be faulty, but fixing it isn’t an option right now. Thanks for any tips you can offer!
Share your real GPU and CPU temperatures. Also, confirm whether you cleaned the dust from the hardware. The system looks good; for software or Windows problems, a clean installation is suggested.
Windows operates this way, treating unused memory as wasted space. The behavior of bugs might persist across different titles or even without mods. It seems like a memory leak is involved. Sims 4 also appears to enforce certain resource restrictions by default.
Le RAM inutilisé representa memoria desperdiciada. Tanto que o sistema operacional pode remover dados menos importantes da memória RAM automaticamente, não há problema.
GPU operates near 50°C and CPU hits 65-70°C. I had it serviced by a local technician for dust removal; they replaced the thermal paste, noting it was nearly gone. They suggested resetting Windows, but heard that a settings reset offers limited benefit. I’ll back up my files as well. Reading about SuperFetch didn’t seem worthwhile—I noticed saving boosts cached RAM by roughly 1GB each time, which is odd. Regarding mods, I disabled them and observed reduced RAM usage; since I haven’t played much, it’s hard to predict if BSoDs would occur. I increased the max limits for Sims, but that’s about all I did—graphics remain unstressed.
All main high-performance settings sit at 3.4ghz average boost. This indicates a memory leak and likely impending failure. You can verify your RAM health simply by testing it. It’s straightforward—use an empty USB drive, install MemTest86, and run a full scan for about an hour.
A memory leak wouldn't appear as a cached issue. @Klumbo Video_TDR_Failure indicates the GPU stopped working, Windows reinstalled the driver, yet the GPU remained unresponsive. This usually points to a defective GPU. Laptops tend to behave differently with their GPU drivers due to video passthrough. Before using DDU, did you uninstall both Nvidia and Intel GPU drivers? Some laptops may encounter problems if you skip this step. Also, for the initial setup and testing, opt for ASUS drivers if available, even if they are outdated—just in case. This guide is provided for reference only.
I executed MemTest by searching for it on the machine and everything appeared normal (no errors). I didn’t test it on a separate stick, though that might matter. Using DDU required removing both Intel and Nvidia drivers. The issue was reinstalling Intel drivers because they weren’t available anywhere, and the Intel installer wouldn’t accept it. Apparently, the installation process has manufacturing restrictions. I replaced the latest Nvidia drivers. I believe you’re referring to Acer software since it’s a laptop from that brand, but even then, a clean reinstall would require backing up everything. It seems the GPU might be damaged, though it’s unusual for it to fail suddenly. If it did, performance would drop sharply within minutes of starting a game. By the time I wrote this, the BSoD reappeared. The logs showed two errors—WhoCrashed followed by an Nvidia driver fault. Memory usage was high, jumping above 16GB when RAM reached that point, then dropping to 14GB but staying higher with more cache. Save operations also increased cache size. Frames stayed smooth until then. Crashes also occurred during saves, sometimes in the middle of a save file. Only Firefox was active in the background, though it can run even without other apps. No problems when playing CPU-heavy games like Guild Wars 2 or MMOs; I don’t have another GPU-heavy title available, but PoE 1 would crash occasionally but is now stable. I’m growing increasingly frustrated with laptops overall.
It seems the Intel drivers usually come from chipset drivers, which you can find on the Acer website. You should definitely use those. It makes sense to keep them updated for performance and stability. I’m not sure about the “too much RAM” warning, but it’s better to avoid unnecessary usage for longer life and efficiency.
