# SamplerDPMPP_3M_SDE - ComfyUI Built-in Node Documentation

> The SamplerDPMPP3MSDE node creates a DPM++ 3M SDE sampler for use in the sampling process.

The SamplerDPMPP\_3M\_SDE node creates a DPM++ 3M SDE sampler for use in the sampling process. This sampler uses a third-order multistep stochastic differential equation method with configurable noise parameters. The node allows you to choose whether noise calculations are performed on the GPU or CPU.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `eta` | Controls the stochasticity of the sampling process (default: 1.0) | FLOAT | Yes | 0.0 - 100.0 |
| `s_noise` | Controls the amount of noise added during sampling (default: 1.0) | FLOAT | Yes | 0.0 - 100.0 |
| `noise_device` | Selects the device for noise calculations, either GPU or CPU (default: "gpu") | COMBO | Yes | "gpu"<br />"cpu" |

Note: All three inputs are advanced parameters.

When `noise_device` is set to "cpu", the standard `dpmpp_3m_sde` sampler is created; when set to "gpu", the GPU-accelerated `dpmpp_3m_sde_gpu` sampler is created.

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `sampler` | Returns a configured sampler object for use in sampling workflows | SAMPLER |
