Frequently Asked Questions
How much VRAM does SuperDeepseek V4 Flash Abliterated MQ 2xDGX need?
SuperDeepseek V4 Flash Abliterated MQ 2xDGX requires 184.1 GB of VRAM at Q4_K_M, or 612.8 GB at BF16. Full 1049K context adds up to 11.5 GB (195.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 306.3B × 4.8 bits ÷ 8 = 183.8 GB
KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
KV Cache + Overhead ≈ 11.8 GB (at full 1049K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run SuperDeepseek V4 Flash Abliterated MQ 2xDGX?
No — SuperDeepseek V4 Flash Abliterated MQ 2xDGX requires at least 130.5 GB at Q2_K, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
What's the best quantization for SuperDeepseek V4 Flash Abliterated MQ 2xDGX?
For SuperDeepseek V4 Flash Abliterated MQ 2xDGX, Q4_K_M (184.1 GB) offers the best balance of quality and VRAM usage. Q5_K_M (218.5 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 130.5 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run SuperDeepseek V4 Flash Abliterated MQ 2xDGX on a Mac?
Yes — Mac Pro M2 Ultra (192 GB) and 3 other Macs can run SuperDeepseek V4 Flash Abliterated MQ 2xDGX. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 184.1 GB of usable unified memory (RAM minus macOS overhead).
Can I run SuperDeepseek V4 Flash Abliterated MQ 2xDGX locally?
Yes — SuperDeepseek V4 Flash Abliterated MQ 2xDGX can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is SuperDeepseek V4 Flash Abliterated MQ 2xDGX?
At Q4_K_M, SuperDeepseek V4 Flash Abliterated MQ 2xDGX can reach ~81 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)
Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.
Example: NVIDIA B200 → 17.7 GB active ÷ (8000 × 0.65) = 3.40 ms, plus 43 layers × 0.055 ms = 2.37 ms, so 1000 ÷ 5.77 ms = ~173 tok/s
Estimated speed at Q4_K_M (184.1 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of SuperDeepseek V4 Flash Abliterated MQ 2xDGX?
At Q4_K_M, the download is about 183.75 GB. The full-precision BF16 version is 612.51 GB. The smallest option (Q2_K) is 130.16 GB.
Which GPUs can run SuperDeepseek V4 Flash Abliterated MQ 2xDGX?
No single consumer GPU has enough VRAM to run SuperDeepseek V4 Flash Abliterated MQ 2xDGX at Q4_K_M (184.1 GB). Multi-GPU or professional hardware is required.
Which devices can run SuperDeepseek V4 Flash Abliterated MQ 2xDGX?
4 devices with unified memory can run SuperDeepseek V4 Flash Abliterated MQ 2xDGX at Q4_K_M (184.1 GB), including Mac Pro M2 Ultra (192 GB), Mac Studio (M3 Ultra, 256GB), Mac Studio (M3 Ultra, 512GB), Mac Studio M2 Ultra (192 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
