Tom's Hardware reports that a software tool ('CMP Unlocker') can restore memory and compute disabled on NVIDIA's CMP 170HX crypto-mining cards — GA100-based cut-down A100s — raising usable VRAM from 8GB to 64GB (or 10GB to 80GB, less reliably) and partially restoring SM throughput and PCIe capability. The exploit reprograms PMU registers via patched drivers rather than fusing hardware off permanently, so no permanent mod is needed, though the cards remain constrained (PCIe 1.0/2.0 x4 hard limits, defective memory stacks on lower bins). Community adoption has been rapid — multi-card builds, a Level1Techs full-memory tester, an lttrlabs teardown of the capacitor/soldering companion mod — but NVIDIA deliberately disabled these stacks, and unlocked cards carry binning, stability, and support risks. Seller prices have reportedly surged from roughly $100–250 to $1,000–3,000 as the tool spread, substantially eroding the original bargain premise.

The only movement since consolidation is the attached BC-250 sibling post spiking against a tiny peer baseline (~5 pts/h absolute) while CMP-specific velocity is zero and new threads are circular buy-vs-Mac deliberations — no new fact touches the verdict. Resolving as absorbed: the unlock is now established community knowledge and the bargain window's close settled the economics; price/reliability watches belong to the standing radar refs and would resurface as fresh episodes.
2026-09-24T07:37:45Z
Post-peak consolidation: CMP-specific flow has collapsed to ~1% of its breakout rate and the newest threads are circular buy-vs-Mac deliberations (0-score posts, sub-0.5 ratios, a fatigue-marked HN repost), so the case's meaning settles — unlock established (64GB reliable on 8GB bins, 80GB effectively dead), bargain window closed at ~$2–3k, and the BC-250 attachment confirms the sibling repurposed-mining-hardware pattern rather than extending the CMP verdict. Demoting accelerating→corroborated and heat high→medium: the wide spread already fired its alert a week ago, and what remains is a standing decision input for gamepc plus a template for how fast cheap-compute arbitrage windows close, not a live opportunity — hence no material change despite the spread valve.

evidence attached: reddit.post.1wou3gr — Independent instance of the repurposed-mining-hardware pattern: $115 AMD BC-250 APUs running Qwen 35B-A3B at 60 tok/s strengthens the case's cheap-hardware economics.

2026-09-22T00:23:55Z
A second multi-card owner now reports receiving four units from a named seller and having them modified to PCIe x16 and tested, modestly strengthening practical procurement and deployment evidence. The same account puts current pricing near $2,700 per card, further separating technical feasibility for existing owners from the original bargain-hardware thesis.
2026-09-20T14:28:38Z
Another owner reports similar bandwidth but a higher stock token rate and no comparable overclocking gain, weakening the headline speedup's generalizability while introducing a potentially more useful result: a 170W power cap without measurable performance loss. Expanding owner experimentation and broad attention sustain high heat, but the opportunity remains optimization of already-owned cards rather than a validated bargain purchase.
2026-09-20T07:22:26Z
Experimentation is moving beyond capacity unlocks and multi-card assembly into performance tuning: a 40GB owner reports a substantial inference speedup from overclocking, although the disproportionate token-rate gain needs controlled reproduction. This expanding implementation frontier warrants accelerating status and continued high attention, but strengthens the case for existing-owner experimentation rather than buying at inflated prices.
2026-09-20T07:22:06Z
evidence attached: reddit.post.1wl9amq — The same repurposed CMP 170HX hardware is being pushed toward useful local inference, materially contextualizing the existing VRAM-unlock case even though the bandwidth claim is unverified.
2026-09-19T23:23:38Z
A purchaser now reports a month of error-free Qwen 27B use on an unlocked 64GB card, strengthening practical feasibility without validating every memory region. Fresh seller-contact reports put obtainable prices far above advertised bargains, shifting the opportunity toward existing owners and early buyers rather than establishing an attractive purchase today.
2026-09-19T13:25:39Z
The newly attached seller inquiry asks for exactly the missing procurement and full-memory validation, but supplies neither a successful purchase nor a test result; it is not additional corroboration or evidence of failure. Breakout attention around the multi-card build and the cross-platform spread reading still justify high heat, without strengthening the purchasing case.
2026-09-19T13:21:56Z
evidence attached: reddit.post.1wklppz — The request seeks independent confirmation of whether unlocked CMP 170HX cards actually sustain full-memory inference, a useful practical check on the case.
2026-09-19T06:23:02Z
The multi-card build is drawing breakout attention, and the spread sensor now warrants high heat even though the supplied discussion adds no new validation. Practical experimentation is corroborated; reliable full-capacity inference and reproducible bargain pricing remain unproven.
2026-09-18T14:28:42Z
A separate builder now reports a 12-card, 768GB CMP deployment, moving the unlock story beyond isolated-card experiments into preliminary multi-card implementation corroboration. The claimed cost advantage is potentially consequential, but neither usable full-capacity inference nor present-day purchasing economics is established without benchmarks, memory-error tests and an itemized build cost.
2026-09-18T14:22:30Z
evidence attached: reddit.post.1wjr59t — A concrete multi-card deployment provides useful independent context on whether repurposed CMP hardware can make memory-heavy local inference economical.
2026-09-17T17:53:29Z
A previously identified owner now asserts near-universal reliability for the 8GB-to-64GB and 10GB-to-40GB unlocks, but supplies neither a test population nor supporting error logs. This reinforces the variant distinction without independently validating reliability or improving the purchasing case; the additional physical-memory claim and research link remain unverified leads.
2026-09-16T06:28:45Z
Discussion now identifies a concrete community repository and distinguishes purportedly stable 40GB operation from the doubtful 80GB path on 10GB variants, but the repository’s contents and claimed results remain unverified. This improves the verification lead rather than establishing usable capacity or restoring the cheap-inference economics thesis.
2026-09-15T23:35:01Z
An owner now reports independently stress-testing two cards, adding preliminary implementation evidence beyond purchase intentions, but the truncated account does not establish tested capacity or sustained inference performance. The newly attached 40GB/80GB question repeats secondhand stability concerns rather than documenting a failed unlock; neither account settles the cheap, usable VRAM thesis.
2026-09-15T23:22:12Z
evidence attached: reddit.post.1whfox6 — User reports firsthand uncertainty about stability limits of the CMP 170HX VRAM unlock, adding practical deployment context to the open case.
2026-09-14T18:44:14Z
The new buyer has ordered a card but has not demonstrated an unlock or inference run; this is a potential verification lead, not independent validation. Comments reinforce already-known pricing concerns and deployment overhead without establishing actual acquisition costs or closing the cheap-VRAM window.
2026-09-14T18:22:33Z
evidence attached: reddit.post.1wga5hj — An independent buyer is testing the reported CMP 170HX VRAM-unlock path, providing useful adoption and practical-cost context for repurposed inference hardware.
2026-09-11T10:30:23Z
A prospective buyer’s report of sharply higher asking prices introduces a potential erosion of the cheap-VRAM thesis before usable inference performance has been established. Without comparable listings or measured CMP results, this is an economics warning to verify, not evidence of either a validated bargain or a closed purchasing window.
2026-09-11T10:22:19Z
evidence attached: reddit.post.1wdbj0e — The purchase comparison provides practical evidence about the rising price and deployment tradeoffs of unlocked CMP-170HX cards for local inference.
2026-09-09T22:32:34Z
The stale-case review adds no substantive evidence: the claimed 64GB owner setup remains a verification lead, not a demonstrated low-cost inference option. Retain the hypothesis without promotion or rejection, and defer further attention until an unlock reproduction, memory-stability result, or CMP-specific inference measurement appears.
2026-09-07T21:30:51Z
The refreshed comments remain configuration speculation and anecdotes from other hardware, not independent validation of usable 64GB CMP memory or practical inference economics. Keep the owner report as a verification lead, but reduce repetitive monitoring until an unlock artifact, memory-stability test, or CMP-specific measured run appears.
2026-09-07T18:24:07Z
The refreshed discussion still offers configuration advice and results on other hardware, not a measured inference run on the claimed unlocked CMP card. The owner report remains a concrete verification lead, but neither useful throughput nor the proposed cheap-memory economics has been established.
2026-09-07T14:37:03Z
The latest comment adds untested layer-splitting advice, not a measured run on unlocked CMP hardware; conflicting model-fit estimates leave the practical configuration unresolved. The owner report remains a useful verification lead, but cheap usable VRAM has not yet translated into demonstrated inference economics.
2026-09-07T13:23:04Z
The refreshed discussion adds SSD-streaming and CPU-only anecdotes, not validation of the unlocked CMP card; model-loading workarounds should not be mistaken for evidence of useful GPU performance. The case still needs a measured run on the claimed 64GB hardware to establish whether cheap capacity translates into practical local-inference economics.
2026-09-07T12:35:09Z
The comments sharpen the practical test: a linked low-bit ExLlama3 configuration may reduce cross-device traffic, while an anecdotal rental report raises doubts about CMP throughput. Neither demonstrates inference on the claimed unlocked 64GB card, so this remains a testable hardware-economics lead rather than a validated cheap-memory option.
2026-09-07T11:27:36Z
An owner now claims a 64GB-unlocked CMP 170HX alongside a 3090, moving this beyond recycled reporting into a concrete verification lead. However, the post asks whether a proposed model configuration will work rather than demonstrating it; usable capacity, stability, inference throughput and purchase economics remain unverified, with PCIe 2.0 x4 an explicit constraint.
2026-09-07T11:22:47Z
evidence attached: reddit.post.1w9p7vy — A practical local-inference setup using an unlocked 64GB CMP card provides context on whether restored VRAM is genuinely useful despite PCIe constraints.
2026-09-05T19:27:42Z
The stale-case check supplies no new observation, leaving this a potentially important hardware-economics report rather than a verified local-inference option. Conflicting capacity claims and the absence of a reproducible unlock or stable inference demonstration still prevent translating the report into a hardware recommendation.
2026-09-03T18:52:26Z
The forced re-evaluation adds no corroboration, artifact, or implementation evidence; the unlock remains an intriguing but unverified hardware-economics claim. Cool the case until an independent reproduction establishes usable capacity, stability, and inference performance.
2026-09-03T18:41:26Z
grounded: known/medium — The radar already tracks this exact development in `radar:cmp-170hx-unlock-verification`. If independently validated, cheap high-VRAM CMP cards could materially
