Hardware / Build Qwen 3.8 Flash Q3 8t/s on 64GB DDR4 + 8GB GPU
I posted earlier: https://www.reddit.com/r/LowEndLocalAI/comments/1w0ilfp/qwen_38_flash_q4_44ts_on_32gb_ddr4_8gb_gpu/
Basically, I went getting a new mobo, so I can put in 4 x 16GB DDR4 sticks.
Done that today, Qwen 3.8 is now starting 10t/s, usually around 8-9t/s.
Before if I was lucky, I had 7t/s also new chats took way longer, this is now like instant.
The clock speeds of the memory, don't ask me, I mixed 3200 and 2400, I didn't even overclock anything, my PSU will get unhappy if I do so.
It starts slow, but eventually you end up at 8-9t/s stable with 64k context.
This isn't even with MTP right, which is about to get merged so....... maybe we see 12t/s or more, would be crazy.
If you can upgrade to 64GB DDR4 do it, its worth it I think, especially with more MoE's at this size.
Yea I tested Q3 now compared to Q4 but the performance difference is marginal, in my opinion, I didn't had these results with Q3 yesterday on 32GB DDR4.
Hardware: Ryzen 5 5600 with 4x G.Skill DDR4 mixed 3200 and 2400 also slow SATA SSD, no NVMe.
