Memory RAM

[Nijat]

Hello Intel Support,

I am contacting you regarding a possible memory compatibility issue involving an Intel Core Ultra 5 250K Plus processor.

My system configuration is:

• CPU: Intel Core Ultra 5 250K Plus

• Motherboard: ASUS Z890 AYW GAMING WIFI W

• BIOS Version: 3020

• Memory Kit: TEAMGROUP T-Force Delta RGB DDR5-6000 CL38
  Part Number: FF3D516G6000HC38ADC01

The system fails to complete POST when the TeamGroup memory is installed.

The following troubleshooting has already been completed:

• CMOS has been cleared.

• BIOS defaults have been loaded.

• Only one memory module was tested in the recommended A2 slot.

• Memory training was allowed to run for more than 10 minutes.

• BIOS was updated to the latest available version.

• Both memory modules were tested individually.

The results are:

• The TeamGroup memory kit works correctly in another Intel-based system.

• My motherboard and processor work correctly with another DDR5 memory kit (Corsair CMK5X32G2B56C40A2-CN DDR5-5600).

• With the TeamGroup memory installed, the CPU and DRAM Q-LEDs cycle during memory training. Eventually all LEDs turn off, but the system never completes POST and no display output is produced.

I have also been in contact with ASUS technical support. After reviewing all test results, ASUS stated that the behavior may indicate a compatibility issue involving the memory SPD/XMP configuration, memory IC revision, BIOS memory training, or the Intel integrated memory controller (IMC) microcode. ASUS has forwarded my case to their engineering team and informed me that Intel may need to be involved if necessary.

Since the memory kit works correctly in another Intel-based system, and the motherboard works correctly with another DDR5 memory kit, I would appreciate it if you could investigate whether this issue could be related to the Intel memory controller or microcode compatibility with this specific memory module.

Please let me know if you require any additional information, logs, BIOS screenshots, or test results.

Thank you for your time and assistance.
