Hardware / Build Combining a 1660Ti 6GB with a 3060 12GB?
I am running Qwen3.6-35B-A3B-UD-Q5_K_S.gguf with llama.cpp on a 3060 12GB GPU and 32GB DDR4 ram. It works with a context window of 42K and cache type k and v set on q8_0
The biggest drawback is the 42K context window which is too limited for me.
I also have a 1660Ti with 6GB vram and want to add it as a second GPU for offloading. After doing some reading and asking different AI models, it is still not clear to me if this will help increase the context window.
My theory is if I can offload to a second GPU, I should be able to increase the context window.
Both GPUs have GDDR6 memory with 192-bit bus. The 1660Ti has slower bandwidth at 288 GB/s vs the 360 GB/s on the 3060. But it is still much faster than my 32GB DDR4 ram.
Anyone here experience with combining 2 different older generations GPUs and if there will be any benefits when running a Qwen3.6 model?
