ASUS Dual RTX 3070 V2 OC 8GB

The ASUS Dual GeForce RTX 3070 V2 OC Edition is a refurbished graphics card built on the NVIDIA Ampere architecture. It delivers 5888 CUDA cores and 8GB of GDDR6 memory across a 256-bit interface. The card connects via PCI Express 4.0 and draws up to 220W through two 8-pin power connectors, requiring a 750W power supply.

Suits 1440p gaming and multi-monitor setups

This card fits builders targeting high-refresh 1440p gaming or productivity across up to four displays using two HDMI 2.1 and three DisplayPort 1.4a outputs. It supports DirectX 12 Ultimate and OpenGL 4.6 for modern titles. The 8GB frame buffer and lack of SLI support make it less suitable for 4K ultra textures or multi-GPU compute workflows.

8GB GDDR6 memory capacity

The 8GB GDDR6 frame buffer at 14 Gbps effective clock determines the texture and resolution ceiling for this GPU. At 1440p the capacity is comfortable for current titles with high settings. At 4K it can become a limiting factor in memory-heavy scenes, so buyers planning 4K ultra should verify VRAM requirements before purchasing.

Questions about this item

What comes in the box with the ASUS DUAL-RTX3070-O8G-V2 and do I need to buy any cables or adapters separately?

The card includes the graphics board with dual axial-tech fans, a protective backplate, and a dual BIOS switch. You must supply a power supply with two 8-pin PCIe connectors and a case that fits a dual-slot, 220 W design. Display cables are not included.

Should I run the card in OC mode at 1800 MHz or Gaming mode at 1770 MHz for my build?

OC mode raises the boost clock to 1800 MHz for higher peak performance in demanding workloads. Gaming mode runs at 1770 MHz with slightly lower power draw and acoustics. Both modes use the same 5888 CUDA cores and 14 Gbps GDDR6 memory.

What does the 14 Gbps memory speed mean for 4K gaming on this RTX 3070?

The 14 Gbps GDDR6 memory on a 256-bit interface feeds the 5888 CUDA cores at high throughput, enabling smooth 4K frame rates in titles that fit within the 8 GB frame buffer. The two HDMI 2.1 and three DisplayPort 1.4a outputs support 7680 x 4320 resolution.
