Qwen Next on 24 + 64 GB VRAM?
A user is inquiring about running Qwen 3.8 Next on a system with a 3090 24GB GPU and a CMP 170HX 64GB GPU, along with 64 GB DDR4 RAM. They are seeking advice on configurations to utilize both GPUs and potentially offload to DRAM, aiming for acceptable speeds. The user notes that the CMP 170HX has a PCIe 2.0 @ 4x bottleneck but has successfully run Qwen 3.7 27B or Minimax H3 at BF16 on it, acknowledging Qwen Next is more demanding.

Hey all,
I now have a 3090 24GB + a CMP 170HX unlocked with 64GB. I also have 64 GB DDR4.
Can I run Qwen 3.8 Next in any possible configuration with both GPUs and perhaps offloading remaining stuff to DRAM? Is there a way I can get acceptable speeds?
The only bottleneck with the CMP 170HX is the PCIe speed (2.0 @ 4x), so that needs to be factored in. It’s usually not much of an issue though IME once model is loaded…
I am successfully running either Qwen 3.7 27B or Minimax H3 at BF16 on the CMP 170HX at decent speed, so I know the GPU is good for it. But Qwen Next is another beast.
Ideas?
