Detailed notes
## Background Published on YouTube by Linus Tech Tips on January 14, 2019, this video explores whether surplus cryptocurrency mining cards without display outputs can be repurposed for gaming instead of going straight to the landfill. The page description highlights how dedicated mining hardware became practically useless after the crypto market drop, questioning whether modified software from Chinese modders can truly turn them into functional gaming GPUs.
## TL;DR Following the 2018 cryptocurrency market crash, Linus and Anthony test a $67 headless Gigabyte P106-100 mining card sourced from Taobao to see if it can game like a standard GTX 1060. Because the card lacks video ports, they pass the rendered frame buffers through an Intel CPU's integrated graphics output on the motherboard. After disabling Secure Boot, toggling Windows Test Signing mode, and running DDU to install an unsigned community-modified driver, the card successfully launches Shadow of the Tomb Raider. Benchmarks show the mining card performing within 3 to 4 FPS of an EVGA GTX 1060 SC, though Linus warns viewers about the serious security risks of untrusted drivers while calling out Nvidia for creating avoidable e-waste.
## Atmosphere & style The video carries an energetic, improvisational tech-lab vibe, epitomized by Linus's admission that they are running the benchmark entirely 'seat of our pants' while a live broadcast is already waiting for them. The banter between Linus and Anthony is casual and geeky, blending humorous procurement anecdotes—like the card being shipped under the customs guise of a computer mouse—with genuine hands-on troubleshooting in BIOS and PowerShell. As the experiment pays off, the mood shifts from playful skepticism to passionate indignation at Nvidia's artificial software locks and the resulting piles of electronic waste.

## Key takeaways - [00:00](https://www.youtube.com/watch?v=TY4s35uULg4&t=0s) The massive 2018 cryptocurrency crash left millions of specialized crypto mining cards stranded without functional secondary market use. - [00:00](https://www.youtube.com/watch?v=TY4s35uULg4&t=0s) The Gigabyte P106-100 shares identical GP106 silicon and 6GB VRAM with the GeForce GTX 1060, but lacks physical display outputs and has gaming workloads disabled by Nvidia drivers. - [00:00](https://www.youtube.com/watch?v=TY4s35uULg4&t=0s) Purchased for $67 on Taobao, the P106 cost less than one-third of the going rate for a standard retail 6GB GTX 1060. - [01:48](https://www.youtube.com/watch?v=TY4s35uULg4&t=108s) Sourcing the card required custom customs labeling to bypass shipping restrictions, arriving heavily coated in dust from industrial mining use. - [01:48](https://www.youtube.com/watch?v=TY4s35uULg4&t=108s) A stock EVGA GTX 1060 SC 6GB established a baseline benchmark of 68 FPS average and 56 FPS minimum in Shadow of the Tomb Raider at 1080p High. - [04:10](https://www.youtube.com/watch?v=TY4s35uULg4&t=250s) Rendering requires a host system with an integrated GPU (iGPU) and motherboard video outputs, mimicking hybrid graphics switching used in laptops. - [04:10](https://www.youtube.com/watch?v=TY4s35uULg4&t=250s) Stock Nvidia drivers recognize the hardware in Device Manager as a P106-100 but block 3D acceleration and deny access to the Nvidia Control Panel. - [07:00](https://www.youtube.com/watch?v=TY4s35uULg4&t=420s) Installing the modified driver requires disabling Secure Boot in the UEFI/BIOS and running bcdedit /set testsigning on in Windows PowerShell. - [11:03](https://www.youtube.com/watch?v=TY4s35uULg4&t=663s) Display Driver Uninstaller (DDU) was necessary to clean previous driver files before Windows Graphic Settings would expose the P106-100 as a selectable high-performance GPU. - [11:03](https://www.youtube.com/watch?v=TY4s35uULg4&t=663s) In Shadow of the Tomb Raider, the P106-100 achieved performance nearly identical to a standard GTX 1060, losing only 4 FPS on average and 3 FPS in minimums. - [11:03](https://www.youtube.com/watch?v=TY4s35uULg4&t=663s) The minor performance penalty is attributable to PCIe bus pass-through overhead combined with the reference clocks of the mining card versus the factory-overclocked EVGA SC card. - [13:38](https://www.youtube.com/watch?v=TY4s35uULg4&t=818s) Running modified drivers from internet forums poses severe malware risks, as typical users cannot audit system-level unsigned driver code. - [13:38](https://www.youtube.com/watch?v=TY4s35uULg4&t=818s) Linus urged Nvidia to stop actively driver-locking mining cards from standard gaming use to prevent tens of thousands of usable GPUs from becoming electronic waste. - [13:38](https://www.youtube.com/watch?v=TY4s35uULg4&t=818s) Because the P106 PCB shares significant layout similarities with standard GTX 1060 boards, manually soldering display ports and SMD components onto the board remains a theoretical hardware modification.
## Detailed walkthrough ### [00:00](https://www.youtube.com/watch?v=TY4s35uULg4&t=0s) The $67 Mining GPU Gamble
Following the massive cryptocurrency market crash in 2018, secondhand marketplaces like eBay were flooded with heavily discounted graphics cards. However, purpose-built mining cards appeared destined for scrap heaps to salvage precious metals like gold. Linus shows off a Gigabyte P106 mining card—a board nearly identical to a standard GeForce GTX 1060 with a dual-fan cooler and a single 6-pin power connector, but handicapped by two massive issues: it possesses zero display outputs, and Nvidia intentionally locked the drivers to prevent gaming workloads.
Despite those hurdles, a vendor on the Chinese marketplace Taobao claimed to have cracked the restriction with modified software, offering modified P106 units for just $67 USD—less than a third of the market price of a legitimate 6GB GTX 1060. Linus resolves to test whether this dirt-cheap e-waste can genuinely be repurposed into a functioning gaming card.
- **GPU model:** Gigabyte P106-100 (mining variant of the GP106 core) - **Power connector:** 6-pin PCIe - **Price paid:** $67 USD on Taobao - **Price comparison:** Under one-third the going rate of a retail 6GB GTX 1060

[01:48](https://www.youtube.com/watch?v=TY4s35uULg4&t=108s) Procurement Shenanigans and Baseline Benchmarks
Anthony joins Linus to walk through the experiment, having managed the logistics behind sourcing the card. Sourcing it proved remarkably difficult because the Taobao vendor refused to ship directly to Canada. Dennis had to intervene, communicating directly with the seller in China, who ultimately skirted shipping restrictions by labeling the package as a humble “computer mouse.” When unboxed, the P106 arrived coated in a thick layer of dust and grime, pointing to months of nonstop mining inside an industrial warehouse.
Before touching the mining hardware, Linus establishes a performance baseline using an EVGA GeForce GTX 1060 SC (Superclocked) 6GB inside their high-end test bench equipped with an Intel Core i9-9900K processor. Both the standard 1060 and the P106 share the same underlying silicon and 6GB VRAM pool, meaning they should theoretically feature identical CUDA core counts. Testing *Shadow of the Tomb Raider* at 1080p on High settings (with motion blur disabled because Linus considers it stupid), the retail GTX 1060 delivers an average frame rate of 68 FPS with a minimum of 56 FPS.
- **Import customs workaround:** Declared and shipped as a computer mouse - **Baseline GPU:** EVGA GeForce GTX 1060 SC 6GB - **CPU:** Intel Core i9-9900K - **Benchmark game:** *Shadow of the Tomb Raider* (1920×1080, High preset, Motion Blur off) - **Baseline performance:** 68 FPS average, 56 FPS minimum

[04:10](https://www.youtube.com/watch?v=TY4s35uULg4&t=250s) The Display Pipeline Problem
Cameraman Brandon voices the obvious hardware paradox: how can anyone game on a graphics card that lacks display outputs? Linus explains that the technique relies on the host PC having a motherboard video output and a CPU with an integrated GPU (iGPU). The system routes the discrete card's rendering output through the motherboard's display connection. Linus notes they previously used a similar pass-through trick to enable FreeSync on Nvidia GPUs using a secondary card, comparing the underlying architecture to laptop hybrid graphics where an efficient integrated chip handles display output while a discrete GPU handles heavy 3D rendering.
```mermaid flowchart LR accTitle: Hybrid Graphics Pass-Through Architecture accDescr: Rendering data flows from the headless P106 GPU through the motherboard and CPU iGPU to reach the monitor.

Linus boots the system using official Nvidia driver 416.16 (from October 2018) via the motherboard video port. While Windows recognizes the card in Device Manager as a "P106-100", the driver will not treat it as a valid 3D accelerator. Venturing into Windows Graphic Settings to assign the game to a high-performance GPU reveals that the OS does not offer the P106 as an option. Furthermore, attempting to launch the Nvidia Control Panel throws an error stating: “You are not currently using a display attached to an Nvidia GPU.”
- **Hardware requirement:** CPU with integrated graphics and a motherboard with video outputs - **Display mechanism:** Frame rendering on the headless GPU, outputted through the CPU's iGPU - **Initial driver tested:** Nvidia Geforce Driver 416.16 (October 2018 release) - **Error encountered:** Nvidia Control Panel blocks access due to lack of a direct display connection

[07:00](https://www.youtube.com/watch?v=TY4s35uULg4&t=420s) Bypassing Windows Security for the Modded Driver
Anthony steps in to take over the software modification, pointing out a desktop folder named "Mining" that contains a modified driver package. Because the driver has had its signatures tampered with, attempting a standard installation results in an immediate failure unless system-level protections are removed. First, they reboot into the UEFI/BIOS settings to disable Secure Boot by clearing the Secure Boot keys. Linus recalls his frustration encountering this design previously:
> “I remember the first time I encountered this I was just absolutely furious because it doesn't even register as a change to the BIOS... I was so mad, I was like, 'What do you mean that's how you disable it? I don't want to delete them forever necessarily.'”
Anthony reassures him that the factory default keys can easily be reloaded later. Once back in Windows PowerShell, Anthony executes `bcdedit /set testsigning on` to enable Test Signing mode, which allows unsigned, modified, or experimental drivers to run.
```mermaid flowchart TD accTitle: Driver Modification and Installation Steps accDescr: Step-by-step workflow to prepare Windows for modified unsigned mining card drivers.
subgraph BIOS["Firmware Configuration"] A["Enter Motherboard UEFI/BIOS"] --> B["Navigate to Key Management"] B --> C["Clear Secure Boot Keys (Disable Secure Boot)"] end
subgraph WindowsConfig["Windows OS Adjustments"] D["Open PowerShell"] --> E["Execute: bcdedit /set testsigning on"] E --> F["Reboot System into Test Signing Mode"] F --> G["Temporarily Disable Windows Update"] end
subgraph DriverSetup["Driver Modification"] H["Uninstall Stock Driver in Device Manager"] --> I["Execute Modified Driver Installer"] I --> J["Acknowledge Unsigned Driver Security Warning"] J --> K["Driver Successfully Installs to P106-100"] end
C --> D G --> H ```
Anthony temporarily disables Windows Update so the OS does not automatically overwrite the driver with standard WHQL packages. He uninstalls the previous driver through Device Manager, noting that while using DDU (Display Driver Uninstaller) is always best practice for stubborn driver problems, they can cut corners here. They launch the modified driver installer; thanks to Test Signing mode, Windows bypasses the hard block, flashes a warning about unsigned software, and installs the driver without crashing. Linus explicitly reminds viewers that running unsigned driver packages sourced from online forums carries significant malware risks:
> “To be clear what we're doing here, we are actually not recommending that you try it at home.”
Once the installer finishes, the card still reports itself as a P106-100 in Device Manager, leading Anthony to inspect the driver details to see if the modified payload took hold.
- **PowerShell command used:** `bcdedit /set testsigning on` - **Security trade-offs:** Disabling Secure Boot and enabling Test Signing exposes the system to unsigned kernel-level software - **Recommended utility mentioned:** DDU (Display Driver Uninstaller) for cleanly purging display drivers
[11:03](https://www.youtube.com/watch?v=TY4s35uULg4&t=663s) Testing the Modded Driver and Running Shadow of the Tomb Raider
With the driver installed, the system confirms it is not digitally signed, which is exactly what was expected for the modified software. Linus and Anthony navigate Windows display settings to set the card as the default graphics processor. Linus admits their testing setup is being assembled on the fly, mentioning that he only developed the methodology two hours prior and the live WAN Show stream had already started three minutes earlier. As Linus puts it: “We're like 1,000% seat of our pants right now.” After running Display Driver Uninstaller (DDU)—which proved to be a necessary step—the Nvidia P106-100 appears in Windows as the selectable high-performance GPU.
```mermaid flowchart LR accTitle: Mining GPU Render Pipeline accDescr: Rendering path from the headless P106-100 mining card across the PCIe bus to the motherboard integrated graphics display output. subgraph Compute ["Compute Stage"] A["Nvidia P106-100<br/>(Headless Mining Card)"] B["Rendered Frames<br/>(Game Engine)"] end subgraph Output ["Display Output"] C["Motherboard DisplayPort / HDMI<br/>(Intel iGPU)"] D["Monitor Display"] end A --> B B -->|"PCIe Bus Transfer"| C C --> D ```
Linus sets the P106-100 as the default device and launches *Shadow of the Tomb Raider*. He underscores that the card cost under $70 USD on Taobao and was originally bound for the scrap heap because it had no video outputs. While the chip could theoretically handle compute workloads, its GTX 1060-tier performance makes it barely worth taking up a PCIe slot for standard compute. To prove there are no visual tricks, Linus traces the physical connection on camera, showing the HDMI cable running directly from the motherboard's rear I/O into the monitor with no connections attached to the mining GPU itself.
The benchmark runs smoothly, yielding performance very close to a standard graphics card: - The mining card averaged just 4 FPS lower than the EVGA SuperClocked GTX 1060 reference run. - Minimum frame rates fell short by only 3 FPS. - The slight performance loss is entirely consistent with the overhead of rendering on a dedicated GPU and routing frame buffers across the PCIe bus through an integrated GPU, combined with the factory clock difference of a SuperClocked model versus stock frequencies.

[13:38](https://www.youtube.com/watch?v=TY4s35uULg4&t=818s) Driver Sourcing, Security Risks, and the E-Waste Dilemma
Although the hack works, Linus explicitly warns viewers against replicating the setup. When Linus asks where the required software came from—since the Taobao vendor provided no guidance—Anthony explains that he actually retrieved it from the Linus Tech Tips community forum. A forum member had compiled detailed documentation alongside a Google Drive link containing the modified, unsigned driver files.
Linus stresses the significant security concerns of using third-party modified drivers. Installing unsigned system-level software poses inherent dangers because regular users cannot verify whether malicious modifications were bundled alongside the display unlock tweaks unless they possess the specialized knowledge to audit the driver code themselves.
``` +------------------------------------+------------------------------------------+ | Factor | Assessment / Detail | +------------------------------------+------------------------------------------+ | Acquisition Cost | Under $70 USD on Taobao | | Driver Status | Unsigned, third-party modified | | Video Outputs | None on card; routed through motherboard | | Shadow of the Tomb Raider Delta | -4 FPS average, -3 FPS minimum vs. SC | | Primary Barrier to Widespread Use | Security hazards of untrusted drivers | +------------------------------------+------------------------------------------+ ```
Linus argues that responsibility for these cards ultimately lies with Nvidia, especially given the massive e-waste footprint of tens of thousands of retired P106 and GTX 1070-class mining boards sitting idle after the crypto market crash:
> “So I'm not asking them to support it, I'm just asking them to not specifically disable it, because this is a serious e-waste problem—literally thousands, tens of thousands of these cards just useful for absolutely nothing anymore when gamers could be gaming on them.”
Looking ahead, Linus and Anthony entertain the idea of obtaining a precision soldering station like Louis Rossmann uses to manually solder physical HDMI connectors and missing SMD components directly onto the board's traces, speculating that the board layouts were likely not altered drastically from standard retail GTX 1060 graphics cards.
