AMD SAM Technology: How to Improve Steam Game Frame Rates

Enabling AMD SAM technology can give your games a real performance boost. Many users see up to a 10% increase in frame rate when playing on high settings. For example, with a Ryzen 5800X3D and Radeon 6700 XT, you might see frame rates jump from 70-80 fps to around 90 fps. You do not need to be an expert to try this. Most modern systems support it, so you can start seeing smoother gameplay quickly.
AMD SAM Technology Benefits
How It Works
amd sam technology helps your computer play games better. Usually, your CPU can only use a small part of your GPU’s memory. This can make games run slower and cause delays. When you turn on this feature, your CPU can use all the GPU memory. This lets your system move game data faster and easier.
Tip: When your CPU and GPU share data faster, you get less lag and smoother games.
This technology removes old limits on how your computer parts talk. It works like a bigger, faster bridge between your CPU and GPU. This means you get lower latency and better use of graphics memory. It helps games run better, especially if they use lots of VRAM.
Impact on Steam Games
You might wonder if this really helps in games. The answer depends on your game and system, but most people see a small frame rate boost and smoother play. Here is a table that shows what happens in some popular games:
Game | Avg FPS (SAM Disabled) | Avg FPS (SAM Enabled) | Min FPS (SAM Disabled) | Min FPS (SAM Enabled) | Frame Time (ms) Disabled | Frame Time (ms) Enabled | VRAM Usage Increase (GB) | CPU Usage Change (%) | Performance Benefit Summary |
|---|---|---|---|---|---|---|---|---|---|
Hogwarts: Legacy | 96 | 100 | 79 | 82 | 11.5 | 10.5 | +0.3 | -1 | Slight increase in avg and min FPS, lower frame time |
The Last of Us Part I | 91 | 103 | 79 | 86 | 12.1 | 10.6 | +1.1 | +13 | Noticeable avg and min FPS increase, lower frame time, higher CPU |
Horizon Forbidden West | 87 | 91 | 78 | 82 | 10.9 | 10.6 | +1.5 | -2 | Slight FPS increase, similar frame time, higher VRAM usage |
Avatar: Pandora Border | 53 | 53 | 43 | 44 | 18.2 | 17.7 | +0.6 | +2 | No significant FPS change, minor frame time improvement |
You can see the gains are usually small, just a few frames per second. Some games get bigger boosts, but others do not change much. Most of the time, you get a small improvement in how games run. This is easiest to see in open-world games or games that use lots of graphics memory.
Note: amd sam technology does not always give a big boost, but it helps your system work better. You might see smoother games and fewer slowdowns, especially in hard-to-run games.

Enable Smart Access Memory
Check Compatibility
Before you turn on smart access memory, you need to make sure your computer supports it. Follow these steps to check if your hardware is ready:
Check your processor. You need at least a Ryzen 5000 series, but some Ryzen 3000 chips might work if your motherboard supports them.
Look at your motherboard. A 500 series board works best, but some B450 boards can also support this feature.
Make sure your Windows uses UEFI mode. You should not have Compatibility Support Module (CSM) turned on.
Go into your BIOS settings and look for “Above 4G Decoding.” This must be enabled.
Find the “Resizable BAR” option in BIOS and set it to “On” or “Auto.”
Test your system after setup. Sometimes, even if your parts look right, you need to check if smart access memory works as expected.
Tip: If you are not sure about your hardware, check your motherboard manual or the manufacturer’s website for details.
