AI-Ready CMP 170HX – Tested, Modified & Verified
This is our premium tested and modified NVIDIA CMP 170HX 8GB, prepared specifically for customers looking to use the CMP 170HX for AI, CUDA, machine learning, inference, and other GPU compute applications.
Unlike standard CMP 170HX cards sold in original configuration, each card in this listing is individually cleaned, tested, unlocked, hardware-modified for PCIe x16 operation, and verified after modification before shipment.
Each Card Includes:
- AI driver unlock tested and verified
- PCIe 2.0 x16 hardware modification completed
- PCIe x16 operation verified after modification
- 64GB memory test completed with 0 errors
- HBM2e memory tested
- PCI Device ID 10DE:20C2 verified
- Card professionally cleaned
- Final functionality test after all modifications
- Secure anti-static packaging
You receive a card that has already gone through the modification and testing process rather than an unverified CMP card requiring additional work after delivery.
GA100 Ampere AI Compute Accelerator
The NVIDIA CMP 170HX is based on the NVIDIA GA100 Ampere architecture, from the same GPU architecture family used in NVIDIA's enterprise compute accelerators.
Originally released as a Cryptocurrency Mining Processor (CMP), the CMP 170HX has attracted significant interest from the AI and GPU-compute community due to community-developed driver unlock solutions that enable broader CUDA and compute functionality.
With unlocked64GB of HBM2e high-bandwidth memory and the PCIe x16 modification performed on the cards in this listing, the CMP 170HX provides an attractive platform for:
- AI inference
- LLM experimentation
- CUDA development
- Machine learning
- GPU compute
- HPC experimentation
- Research and development
- Multi-GPU compute systems
Professional PCIe 2.0 x16 Modification – Completed & Verified
Standard CMP 170HX hardware is configured with a restricted PCIe interface.
The cards sold under this listing have undergone the required hardware capacitor modification to enable PCIe 2.0 x16 operation.
The modification is performed as professional component-level PCB work, with careful capacitor placement and inspection after soldering.
You do not need to perform the capacitor modification yourself.
Professional Cleaning & Hardware Preparation
These are used enterprise/mining compute cards, so proper cleaning and inspection are important.
Each card is opened and inspected as needed, with accumulated dust and debris removed from the heatsink, enclosure, PCB area, and airflow path.
Where necessary, we also replace or restore small hardware components such as:
- Power adapter cable
- Power-cable retaining clip/bracket
- Missing or damaged retaining hardware
- Loose or damaged external hardware
The goal is not simply cosmetic cleaning. We prepare each card for reliable continued use and strong forced-air cooling.
Final Verification Before Shipment
After cleaning, modification, and preparation, every card goes through final validation.
Our verification process may include:
memtest_vulkan
Extended GPU memory-address testing to check for memory errors.
Target result: 0 errors
gpu-burn
Sustained GPU load testing to confirm the card remains operational and stable under compute load.
nvidia-smi
Used to confirm GPU detection, driver status, memory visibility, temperature, power behavior, and general operating condition.
PCIe Link Verification
The modified card is checked to confirm that the PCIe interface negotiates at:
PCIe Gen2 x16
OpenCL Benchmark
Compute functionality and performance are verified through an OpenCL workload.
Device Identification
The preferred PCI Device ID is confirmed:
10DE:20C2
AI Unlock – Tested & Verified
These cards use the preferred:
PCI Device ID: 10DE:20C2
Each card is tested in a compatible AI-unlock environment to confirm that it is properly recognized and operational for compute use before shipment.
The unlock is verified on the card before shipment.
Please note that software and driver configuration on the buyer's own system may still be required. Compatibility can depend on the operating system, NVIDIA driver version, motherboard, BIOS configuration, Kernel / system configuration, AI-unlock software version.
Community AI/unlock software is third-party software and is not developed or maintained by NVIDIA or by us.
HBM2e Memory Testing – 0 Errors
Memory condition is especially important when purchasing used compute accelerators.
Each card undergoes an extended memory test before shipment.
Verified:
64GB Memory Test Completed
0 Memory Errors
The 64GB figure refers to the amount of memory tested during the test procedure—it does NOT mean that the GPU contains 64GB of VRAM.
The CMP 170HX itself is equipped with:
8GB HBM2e High-Bandwidth Memory
Testing results can be provided for the individual card upon request when available.

What Makes This Version Different?
Those cards may still require:
- Cleaning
- Memory testing
- AI unlock setup
- PCIe capacitor modification
- PCIe x16 verification
- Load testing
- Hardware inspection
Our premium cards have already gone through the major preparation process:
CLEANED → INSPECTED → AI UNLOCK TESTED → MEMORY TESTED → PCIe x16 MODIFIED → LOAD TESTED → FINAL VERIFICATION
This version is intended for customers who would rather receive a prepared and verified compute card instead of performing the hardware modification and initial validation themselves.
What’s Included
- 1 x NVIDIA CMP 170HX 8GB GPU
- 1 x Power Adapter Cable
- Secure anti-static packaging
Cooling Requirement
The CMP 170HX uses a passive server-style heatsink and requires strong forced airflow.
Do not operate the card without adequate airflow.
For open-air testing, we recommend using a high-static-pressure fan or blower directed through the heatsink.
Proper airflow is especially important during sustained AI, CUDA, and GPU-compute workloads.
