Preface

This manual has been tested for the following types and families of GPU accelerators:

Nvidia Tesla T4 – simultaneous operation of 3 accelerators on the motherboard;
Nvidia Quadro P620 – simultaneous operation of 4 accelerators on the motherboard.

Procedure for launching graphics accelerators

Nvidia Tesla T4

1. Remove power from the server;

2. Install graphics accelerators in the PCIe x16 slots of the motherboard (x8 with the ability to install x16 expansion cards in them);

3. Apply power to the server;

4. Wait for the image to appear on the screen. Hold down the "ESC" key and wait to enter the BIOS menu;

5. Go to Setup Utility -> Advance -> Socket Configuration -> Common RefCode Configuration;

6. Make settings as shown below; the values of the first three functions are required and the rest are default:

	Common RefCode Configuration
1	MMCFG	512M
2	MMIO High Base	56T
3	MMIO High Granularity Size	1024G
4	Isoc Mode	Auto
5	Numa	Enabled
6	Publish SRAT	Enabled
7	SRAT Memory Hot Plug	Disabled
8	SRAT CPU Hot Plug	Disabled

7. Press "F10" button (Save and exit).

Nvidia Quadro P620
