Refurbished RTX 3070 Ventus 3X 8G OC LHR

This refurbished MSI Ventus card fits gaming rigs and workstations that need a GeForce RTX 3070 with 8GB GDDR6 on a 256-bit bus. The triple-fan cooler and graphene backplate keep the 220W TDP in check while a 1755 MHz boost clock drives 5888 CUDA cores through a PCI Express 4.0 x16 slot.

Replaces older cards with 25 MH/s ETH hash rate

The LHR variant caps Ethereum mining at roughly 25 MH/s, so it serves builders who want gaming performance without the hash-rate premium of non-LHR models. It steps up from earlier 6GB or 8GB 256-bit GPUs when 14 Gbps memory and DirectX 12 Ultimate support become the baseline for new titles.

8GB GDDR6 handles 1440p ultra and entry 4K

The 8GB frame buffer and 256-bit interface comfortably run modern games at 1440p ultra settings and manage lighter 4K workloads. Memory headroom tightens in heavy 4K texture packs or multi-monitor 7680 x 4320 setups, where the 8GB limit can force texture streaming or resolution scaling.

Questions about this item

How much case length does the triple-fan Ventus 3X cooler require?

The triple-fan thermal design uses TORX Fan 3.0 blades and core pipes that span the full heatsink length, so measure your chassis clearance against the card's full PCB plus cooler overhang before ordering.

Which power cables must be connected for the 220 W TDP board?

Two 8-pin PCIe connectors are required; the common mistake is seating only one or using a single daisy-chain cable, which can cause instability under load.

When should the graphene backplate and fan bearings be inspected?

Check the backplate for dust buildup and spin each TORX Fan 3.0 rotor every six months; replace any fan that develops noise or resistance to keep the 220 W thermal solution effective.
