Lenovo ThinkStation P620 Tower Workstation
Overview
The introduction to the new Chagall Workstation processors expands the AMD Ryzen Threadripper Pro Series lineup. AMD and Lenovo have collaborated to enable Chagall CPU upgrades on the existing P620 platform using Castle Peak CPU. The Chagall CPU is a drop in compatible part that requires only a basic system BIOS update in order to function.

Update BIOS
Updating system BIOS is a critical first step to allow the P620 platform to
support the new Chagall family of CPUs. Support for Chagall CPUs was added to
BIOS is a staged approach, so it is critical that the proper flashing
sequences be followed in order to ensure BIOS is updated successfully. The
flash sequence will be determined by the starting BIOS that is installed on
the target P620 system. Table 1 below shows the proper flash procedures based
on the starting BIOS level. Note that up to two separate flash procedures
might be necessary based on the starting BIOS version.
Think Station P620 BIOS version update process to support Chagall processors.
If starting BIOS is < BIOS 26A… | If starting BIOS is >= 26A… |
---|
1. Flash to BIOS 26A first.
Note – Refer to special instructions below if starting BIOS is 21A or 22A.|
1. Flash to BIOS 45A (or latest available BIOS).
2. Flash to BIOS 45A (or latest available BIOS).| 2. Proceed with physical
CPU installation.
3. Proceed with physical CPU installation.|
Note:
It is critical that system BIOS be upgraded successfully as highlighted above
prior to the Chagall CPU installation. Otherwise, the system could fail to
boot properly.
Lenovo recommends using BIOS S07KT45A (45A) or higher when using Chagall CPUs
in the P620 platform.
Special Instructions for Starting BIOS 21/22A
If the starting BIOS version is BIOS S07KT21A (BIOS 21A) or S07KT22A (BIOS 22A), an additional step must be taken during the flash process to ensure it completes successfully. Follow the steps below if the starting BIOS is 21A or 22A:
- With the system powered off, locate jumper JP55 on the P620 motherboard.
- Move the jumper from the default position connecting pins 1-2 to the disabled position which connects pins 2-3.
- Run the BIOS flash update for BIOS 26A as instructed.
- Once the flash update for 26A completes successfully, power off the system and move JP55 back to the default position connecting pins 1-2.
- Follow the general BIOS Flash Update Procedure steps listed in the next section.
Special Instructions for Starting BIOS 0EA
If the starting BIOS version is BIOS S07KT0EA (BIOS 0EA) or earlier, it is critical to note to make sure BIOS Simultaneous Multithreading (SMT) is set to ‘Enabled’ prior to performing a BIOS update. Here are some quick step-by-step instructions to ensure BIOS is set correctly.
-
Boot into BIOS F1 setup.
-
Select the ‘Advanced’ menu option, then ‘CPU Configuration’.
-
Select the drop-down menu for Simultaneous Multithreading and make sure this is set to ‘Enabled’.
-
Select F10 to Save and Exit BIOS setup and follow the general BIOS Flash Update Procedure steps listed in the next section.
General BIOS Flash Update Procedure
Note:
Select the BIOS update package that suits your need such as flash from
Windows operating system, flash from EFI shell, or flash from ISO image.
-
Flash BIOS to S07KT26A. Refer to the readme file in the BIOS update package for specific instructions on each flash method.

CPU Removal and Installation
Please refer to the following document with step-by-step instructions on how
to remove and install the new Chagall Workstation CPUs.

CPU Fusing
The Think Station P620 platform supports AMD’s Platform Secure Boot (PSB)
technology, which provides robust security against remote hackers that could
seek to embed malware into system firmware. As a result of supporting PSB, any
Threadripper Pro CPU that is installed in the P620 platform will be bound via
a one-time programmable fuse to Lenovo’s signed BIOS code. From that point
on, the fused processor will only function on motherboards using Lenovo’s
code signing key.
The following prompt will appear during POST on the first boot with a new
processor.
Notes:
- Press ‘Y’ to continue to fuse the CPU to the board. This is non-reversible.
- Press ‘N’ to shutdown the system without fusing CPU to the board. This will not continue to boot and will instantly shutdown the system.
