Can the Rockchip RK3568 NAS (4 GB) run LFM3 1.7B?

Yes, but slowly (tight fit)

Slow (tight fit). At Q3_K_M it needs about 1.7 GB of 2.0 GB usable, with an estimated speed of 3.3 tok/s.

Best quant: Q3_K_M
Generation speed: 3.3 tok/s
Prompt processing: 6.9 tok/s
First token (1K prompt): 147.6 s

Best app to run it on the Rockchip RK3568 NAS (4 GB)

On Linux on ARM boards

Command line + local API · runs on llama.cpp (ggml), MLX (Apple silicon, preview)

One command with Ollama’s own build of this model.
Serves an OpenAI-compatible API that other apps and coding tools can use.

ollama run lfm3:1.7b

llama.cpp Usually the first to support new model architectures.

Want an agent? LFM3 1.7B supports tool use, so you can pair a llama.cpp or MLX LM server with one of these. Apps that run on this computer come first.

How it’s rated

Quality 47Fair quality (C) · 47 of 100: how capable the model is at Q3_K_M, whatever it runs on. Match score 64/100 (quality, fit, speed and memory use) sets the ranking.: How capable the model itself is at Q3_K_M, from its editorial quality tier scaled by the quantization or precision. It’s the same on any hardware that runs this variant. Scale: A+ 85+ · A 70+ · B 55+ · C 40+ · D under 40.
Runs Slowtight fit: How well it runs on the Rockchip RK3568 NAS (4 GB): speed, capped by how well it fits in memory. Runs great: 30+ tokens/s (or near the image, video or decision speed target) · Runs well: 10+ tokens/s · Slow: 3+ tokens/s · Very slow: under 3 · Won’t run: doesn’t fit even with offload. A tight fit or RAM offload caps it at Runs well; heavy offload caps it at Slow.

Match score

To order lists, each result also gets a match score out of 100 from four parts. It favors the most capable model that still runs well.

Model qualityEditorial quality tier of the model, scaled by the quantization or precision used.	21.2 / 45
Memory fitFull marks when the model fits in the share of the NAS’s memory that models can use (the rest stays with the NAS system and its storage services); fewer when it goes past that limit.	24.0 / 25
SpeedGeneration speed against a 40 tokens/s target for LLMs, or render time against a target for image and video.	4.3 / 15
Memory useRewards using the memory you have, so a bigger, better variant beats a tiny one that leaves most memory idle.	15.0 / 15
Match score	64.5 / 100

The match score orders results; it is not shown as a grade. Quality and Runs are the two ratings in the tables.

Quick answers

How much memory does LFM3 1.7B need on the Rockchip RK3568 NAS 4GB?

At Q3_K_M it needs about 1.7 GB. The Rockchip RK3568 NAS 4GB has 2.0 GB usable.

How fast is LFM3 1.7B on the Rockchip RK3568 NAS 4GB?

About 3.3 tok/s at Q3_K_M, an estimate from the hardware’s memory bandwidth and the size of the model.

Which quantization of LFM3 1.7B should I use on the Rockchip RK3568 NAS 4GB?

Q3_K_M. Of the versions that fit, it is the one that runs best; when two run equally well, the check prefers the higher-rated one.

Estimates come from published hardware specs and our open formulas, not from running the model on your machine. Real speed varies with runtime, drivers and settings. Numbers marked “Measured” come from a linked benchmark.
