Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 424.0 GB, but this setup only exposes 108.8 GB of usable shared or unified memory.
Move to a larger memory pool
A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.

No, DeepSeek V3.2 requires more memory than NVIDIA DGX Spark 128GB provides.
DeepSeek V3.2 (671B parameters) requires approximately 424.0 GB of memory with Q4_K_M quantization.
The recommended quantization for DeepSeek V3.2 is Q4_K_M, which balances quality and memory efficiency.
On NVIDIA DGX Spark 128GB, DeepSeek V3.2 achieves approximately 2.0 tokens per second decode speed with a time-to-first-token of 96800ms using Q4_K_M quantization.
For coding workloads, DeepSeek V3.2 on NVIDIA DGX Spark 128GB receives a F grade with 2.0 tok/s and 4K context.
On NVIDIA DGX Spark 128GB, DeepSeek V3.2 can safely use up to 4K tokens of context. The model's official context limit is 128K, but available memory constrains the safe maximum.

Move to a larger memory pool. A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.
Not always. NVIDIA DGX Spark 128GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
