NVIDIA VRAM Test USB — Legacy Edition (v2.1) Supports GTX 6XX Up to RTX 5090

A clean, plug-and-play Legacy/BIOS (CSM) bootable USB image curated by GPU Solutions for
quick and reliable NVIDIA VRAM testing on older or finicky platforms. This build organises tools, scripts,
and documentation into a simple menu so you can boot, run tests, and export logs consistently —
no commands, no coding, no experience required.
You’re purchasing convenience, curation, and documentation—not the proprietary tools themselves.

Who is this for?

• Technicians and enthusiasts working with older motherboards or systems where UEFI is unavailable or unstable.
• Shops that want a repeatable, log-first workflow across mixed hardware generations.

What you get

• Legacy/BIOS bootable image with a fully guided menu system — no commands required.
• Menu-driven workflow: Run tests, view reports, and manage everything with just a few key presses.
• Optional terminal access: Power users can still drop into the terminal if preferred.
• Upgraded display resolution: Now runs at a higher resolution for a cleaner, more readable interface — a significant improvement over the 480p display in v1.0.
• Curated scripts that run automatically through the menu — no coding knowledge needed.
• Organized /logs output (bank/channel hints like A0/A1, B0/B1, etc.).
• Quick-start README (inside the ZIP) with step-by-step instructions and tips.

Why this build?

• Zero commands required: Everything from running tests to viewing reports is handled through the menu system — just press a few keys.
• No programming knowledge needed: The entire workflow is guided — anyone can use it.
• Better display: No more squinting at a cramped 480p screen — runs at a higher resolution for a much more comfortable experience.
• Maximum backwards compatibility: Boots on platforms that struggle with UEFI.
• Zero clutter: Clean environment, predictable paths, repeatable results.
• Terminal option available: Prefer the command line? You still have full terminal access.
• Support-friendly: When you share your /logs, we can help you interpret them quickly.

Important notes (read before purchase)

• The test identifies failing banks/channels (e.g., A0/A1), but that does not prove a specific VRAM IC is bad. Root cause can also be pads under the VRAM or pads under the GPU core. Treat results as a diagnostic step, not the final verdict.
• This is a Legacy/BIOS (CSM) build. On some systems, you may need to enable CSM/Legacy Boot and/or disable Secure Boot to boot.
• For modern boards, consider the UEFI Edition. Many shops keep both for full coverage.
• AMD CPUs DO NOT work with Nvidia MATS and MODS.
• Intel CPUs between the 3rd Gen and 8th Gen are compatible with MATS and MODS.

What’s included vs. not included

• Included: Curated boot image, menu system, scripts, docs, and a structured workflow.
• Not included: Any proprietary software licenses; we are providing packaging and documentation for convenience.

Support

• Basic support for installation/boot issues and log interpretation basics.
• For help, reply to your order email and attach your /logs folder, or contact: [email protected].

Refunds

Because this is a digital download, all sales are final once the download starts.
Please verify compatibility (Legacy/CSM boot) before purchase.

Bundle option (recommended)

Prefer maximum compatibility across new and old systems? Get the UEFI + Legacy bundle.
Many repair shops keep both on a single USB (via a multi-boot tool) to cover edge cases.

Changelog

• v2.1 — June 2026:
  • Bug Fixes: Power Off and Restart no longer hang when triggered from boot.
  • GPU Corrections: RTX 3050 Ti removed (model does not exist). RTX 4060 Ti correctly moved to GDDR6X category. RTX 3070 Ti correctly separated from RTX 3070 (GDDR6X, not GDDR6).
  • Display Setup Improvements: GDDR6 GPUs no longer require MODS to be run before MATS or NVMT — tests can now be run in any order. GDDR6X and GDDR7 GPUs now show a warning to run MODS before MATS and NVMT. NVMT warning removed from GDDR6 GPU sub-menu.
• v2.0: Introduced fully guided menu system — run tests, view reports, and manage everything with just a few key presses. Zero commands required. No programming knowledge needed. Terminal access still available for advanced users. Display upgraded from 480p to a higher resolution for a cleaner, more comfortable interface. Support range updated to GTX 6XX up to RTX 5090.
• v1.0: Initial Legacy release — cleaned build, organized menus, default scripts, log collector, README.
