What mining algorithms is the SZSJKJ RTX 2080 Ti 22GB best suited to in Australia in 2026?

The SZSJKJ RTX 2080 Ti 22GB is a unique variant of the Turing architecture GPU equipped with 22GB of GDDR6 memory which is substantially more than the standard 11GB RTX 2080 Ti. This expanded VRAM makes it especially valuable for memory-intensive mining algorithms and AI workloads. For mining in 2026 strong targets include Autolykos v2 for Ergo where higher VRAM benefits dataset caching, KawPow for Ravencoin, and Octopus for Conflux. The 352-bit memory bus provides high bandwidth that benefits memory-bound mining algorithms. The 22GB capacity also supports large AI model inference workloads as a secondary use case.

Is the SZSJKJ RTX 2080 Ti 22GB profitable on Australian electricity rates?

The RTX 2080 Ti draws 250-280 watts at stock under mining load which is significant at Australian electricity rates of $0.25-$0.35 per kWh. Applying a power limit reduction to 170-190 watts in MSI Afterburner or HiveOS typically retains 90-95 percent of hashrate while improving efficiency meaningfully. At Australian residential tariffs profitability is algorithm and coin-price dependent. The 22GB VRAM opens access to higher-value AI compute workloads via marketplaces like Vast.ai and RunPod which can provide an alternative revenue stream alongside or instead of traditional mining.

Can the SZSJKJ RTX 2080 Ti 22GB be used for AI inference workloads as well as mining in Australia?

Yes. The 22GB GDDR6 VRAM is one of the largest memory capacities available on a consumer-class Turing GPU and is sufficient for running large language models and image generation models at full precision that would not fit on standard 8-12GB cards. Platforms like Vast.ai, RunPod, and Salad allow Australian GPU owners to rent compute time to AI users providing income when dedicated mining may be less profitable. This dual-use capability is a meaningful advantage of the 22GB variant over standard 11GB RTX 2080 Ti cards in 2026.

What OC settings should I use on the RTX 2080 Ti for GPU mining in HiveOS or Windows?

For the RTX 2080 Ti on Ergo Autolykos v2 and KawPow target a core clock offset of -100 to -200 MHz, memory clock offset of +500 to +800 MHz, and power limit of 60-70 percent of TDP targeting around 165-190 watts. Memory overclocking is the primary hashrate lever on Turing for most mining algorithms. In HiveOS use the Nvidia OC settings with core clock as absolute MHz, memory clock offset, and power limit percentage. Monitor GPU memory temperature as GDDR6 on 2080 Ti can run warm and ensure adequate open-frame airflow to keep memory junction below 90 degrees Celsius.

Does MinerHub provide warranty and shipping for the SZSJKJ RTX 2080 Ti 22GB across Australia?

Product Details

The SZSJKJ GeForce RTX 2080 Ti 22GB is a remanufactured NVIDIA Turing card with extended memory. The unit is built around the TU102 die with 4352 CUDA cores, 544 tensor cores, and 68 RT cores, paired with 22 GB of GDDR6 memory across the full 352-bit memory bus — double the 11 GB found on stock retail RTX 2080 Ti cards. These extended-memory variants are produced by Chinese rebuilders using salvaged TU102 dies (often from server-pull or refurbished sources) combined with higher-density GDDR6 modules and a custom PCB designed for the doubled capacity.

Important transparency note: this is not a factory NVIDIA product. It is a third-party rebuild of the RTX 2080 Ti reference design with modified memory. The card identifies as an RTX 2080 Ti to Windows and uses the standard NVIDIA GeForce driver stack with no modification required. Warranty is provided by the rebuilder/seller rather than NVIDIA. Performance in gaming and most mining algorithms is comparable to a stock 2080 Ti — the value of the modification is in the 22 GB VRAM headroom for AI/ML inference, large-DAG mining algorithms, and creator workloads with heavy memory demands.

For GPU mining, approximate hashrates with tuned clocks: Etchash (Ethereum Classic) ~58–60 MH/s at ~220 W, Autolykos2 (Ergo) ~190–210 MH/s at ~180 W, KawPow (Ravencoin) ~32–35 MH/s at ~230 W, Octopus (Conflux) ~78–85 MH/s at ~240 W. The 22 GB frame buffer provides multi-year headroom for DAG growth on every current GPU-mineable algorithm, and opens up workloads that 11 GB cards cannot handle — for example, hosting larger AI inference models alongside mining when the card is idle.

For Australian operators, the card draws approximately 250–260 W TDP from 2 × 8-pin PCIe connectors (some rebuild revisions use 8+6-pin), with a recommended PSU of 650 W+ for a single-card build. The 2080 Ti is a large dual-slot card — typical dimensions are around 270 × 116 × 38 mm in the reference-style cooler. A licensed electrician should be consulted for circuit planning on multi-card rigs, and installations must comply with AS/NZS 3000:2018. As a refurbished/remanufactured product sold in Australia, the card is fully covered by Australian Consumer Law guarantees of acceptable quality.
