ASUS TUF Gaming A17 AMD Ryzen 9 7940HS VRAM Insufficient Fix Windows 11

Games on your ASUS TUF Gaming A17 AMD Ryzen 9 7940HS show an out of VRAM error, textures fail to load at high settings, or frame rates drop severely during scenes with many detailed textures. Game graphics settings adjustment and AMD Radeon configuration manage VRAM usage effectively on the TUF Gaming A17 AMD.

This guide covers game VRAM optimization, AMD FSR configuration, and Smart Access Memory for the ASUS TUF Gaming A17 AMD Ryzen 9 7940HS in Windows 11.

“TUF Gaming A17 AMD Ryzen 9 7940HS ran out of VRAM in The Witcher 3 with Ultra texture settings at 1080p. Dropped textures to High and VRAM usage went from 9.2GB (over limit) to 6.8GB. Game ran smoothly with no texture errors. Ultra textures need 12-16GB VRAM for some titles.” – Azri, game enthusiast from Cheras

Why VRAM Runs Out on ASUS TUF Gaming A17 AMD

Modern games at Ultra texture presets load uncompressed high-resolution textures that can require 10-16GB of VRAM, exceeding the 8GB GDDR6 available on the ASUS TUF Gaming A17 AMD RX 7600S or RX 7700S. When VRAM fills completely, Windows begins using system RAM as VRAM overflow (through AMD Smart Access Memory or driver-managed overflow), but system RAM bandwidth (51.2GB/s for DDR5-6400) is significantly lower than GDDR6 VRAM bandwidth (288GB/s for RX 7700S), causing severe stuttering as textures are streamed from system RAM. Games detect this VRAM exhaustion and show an insufficient VRAM warning encouraging settings reduction.

• Ultra texture preset requiring 10-16GB VRAM exceeding 8GB RX 7700S GDDR6 capacity
• Multiple games or resource-heavy Discord/browser open simultaneously consuming shared VRAM
• High resolution (1440p) increasing VRAM requirements for framebuffer and render targets
• Ray tracing enabled consuming additional VRAM for BVH acceleration structure and denoising buffers

Fix 1 – Lower In-Game Texture Quality

In the game graphics settings, change texture quality from Ultra to High or Medium. Ultra textures load full 8K or 4K resolution uncompressed texture maps for objects in view, while High settings use 2K or 2K compressed textures that provide nearly identical visual quality at 1080p viewing distance but require 40-60 percent less VRAM. For the ASUS TUF Gaming A17 AMD with 8GB VRAM, High texture settings at 1080p typically use 5-7GB of VRAM, well within the 8GB limit, while Ultra may push 9-12GB in texture-heavy open world scenes. After lowering textures to High, open AMD Radeon Software – Performance – Metrics tab to monitor real-time VRAM usage during gameplay – target below 7.5GB to maintain texture streaming headroom.

Fix 2 – Enable AMD FSR for Lower Render Resolution

In supported games, enable AMD FidelityFX Super Resolution (FSR) at Quality or Balanced preset. FSR renders the game at a lower internal resolution (66-77 percent of display resolution at Quality preset) and upscales to 1080p with minimal visual quality loss. Lower internal rendering resolution reduces VRAM required for the framebuffer, depth buffer, and render targets – at Quality preset, FSR typically reduces VRAM requirements by 20-30 percent compared to native 1080p rendering. With FSR enabled at Quality, the ASUS TUF Gaming A17 AMD can often maintain High or even Ultra textures without VRAM exhaustion in many titles. FSR also provides an average 30-50 percent FPS improvement by reducing GPU rendering workload at the same time.

Disable Ray Tracing for VRAM Savings

Disable ray tracing (RT) in game graphics settings. Ray tracing on AMD RDNA 3 architecture (RX 7600S/7700S) requires VRAM for the BVH (Bounding Volume Hierarchy) acceleration structure that stores scene geometry for ray intersection tests, plus additional VRAM for denoising buffers. In ray-tracing-heavy scenes, BVH and denoising buffers can add 1-2GB of VRAM consumption on top of texture and framebuffer requirements. Disabling RT while keeping High textures reduces total VRAM to 5-6GB for most games, well within the 8GB limit and eliminating VRAM exhaustion while maintaining better visual quality from high textures than the alternative of Low/Medium textures with RT enabled on the TUF Gaming A17 AMD.

Fix 3 – Enable AMD Smart Access Memory

Open Lenovo Vantage or ASUS Armoury Crate – check if Smart Access Memory (SAM) or Resizable BAR is enabled. In BIOS, navigate to Advanced – PCIe settings and ensure Resizable BAR Support is enabled (required for SAM/ReBAR). With SAM enabled, the AMD Ryzen 9 7940HS CPU can access the full 8GB GDDR6 VRAM directly at full bandwidth rather than the default 256MB BAR window. SAM improves performance in AMD Radeon GPU + AMD CPU platforms by 5-15 percent in many games, and more importantly for VRAM management, allows the GPU driver to more efficiently utilize the full 8GB VRAM capacity for texture streaming, reducing overflow to system RAM that causes stuttering when VRAM is nearly full on the ASUS TUF Gaming A17 AMD.

Fix 4 – Close Background Applications Before Gaming

Close Discord, web browsers (Chrome with many tabs each consuming 50-150MB GPU memory for hardware acceleration), Spotify, and other background applications before launching VRAM-intensive games. Background applications with GPU hardware acceleration enabled consume 500MB-1.5GB of total VRAM for their rendering surfaces, browser GPU cache, and video decode buffers. On an 8GB VRAM system, this leaves only 6.5-7.5GB for the game. Closing all GPU-accelerated background applications before gaming maximizes available VRAM for the game’s texture and render target allocations, reducing the frequency of VRAM exhaustion and texture streaming errors in high-VRAM-demand titles at High or Ultra settings on the ASUS TUF Gaming A17 AMD Ryzen 9 7940HS.

Frequently Asked Questions

How do I fix VRAM insufficient error on ASUS TUF Gaming A17 AMD Ryzen 9 7940HS?

Lower texture quality from Ultra to High. Enable AMD FSR Quality preset. Disable ray tracing. Close background GPU applications (browsers, Discord). Enable AMD SAM/ReBAR in BIOS.

How much VRAM does ASUS TUF Gaming A17 AMD Ryzen 9 7940HS have?

RX 7600S or RX 7700S with 8GB GDDR6 VRAM. High textures at 1080p use 5-7GB. Ultra textures may exceed 8GB in open-world games. FSR reduces VRAM requirements 20-30 percent.

Can I increase VRAM on ASUS TUF Gaming A17 AMD Ryzen 9 7940HS?

No – GDDR6 VRAM is soldered on GPU die, not upgradeable. AMD Smart Access Memory (SAM/ReBAR) improves VRAM bandwidth utilization without physical capacity increase.

Why does ASUS TUF Gaming A17 AMD run out of VRAM at 1080p?

Ultra texture presets in modern games require 10-16GB exceeding 8GB limit. High textures use 5-7GB at 1080p for comfortable headroom. FSR Quality reduces requirements further 20-30 percent.

Conclusion

ASUS TUF Gaming A17 AMD Ryzen 9 7940HS VRAM insufficient errors in Windows 11 are resolved by lowering in-game texture quality from Ultra to High (reducing VRAM use 40-60 percent), enabling AMD FSR Quality preset (reducing render resolution VRAM 20-30 percent), and disabling ray tracing (saving 1-2GB BVH and denoiser VRAM). AMD Smart Access Memory via BIOS ReBAR enable improves full 8GB VRAM utilization efficiency on the Ryzen 9 7940HS + RDNA 3 platform. Closing GPU-accelerated background applications before gaming frees 0.5-1.5GB VRAM for game texture allocation, reducing VRAM exhaustion in texture-heavy open-world titles on the ASUS TUF Gaming A17 AMD.
