5.6.3 Compatibility Refer to the following rules to select the DDR5 DIMMs. ) IMPORTANT • A server must use DDR5 DIMMs with the same part number (P/N code). All DDR5 DIMMs operate at the same speed, which is the lowest of: - Memory speed supported by a specific CPU. - Maximum operating speed of a specific memory configuration. • Mixing DDR5 DIMMs of different specifications (capacity, bit width, rank, height, etc.) is not supported. • For specific memory options, consult your local sales representative or refer to 7.2 Hardware Compatibility. • DDR5 DIMMs can be used with the Intel Xeon 6 processors (Birch Stream-SP). The maximum memory capacity supported may vary by CPU models. • The maximum number of DIMMs supported varies with the CPU type, DIMM type and rank quantity. 25 White Paper for KAYTUS KR2280V3 Series Servers Powered by Intel Processors NOTE Maximum number of DIMMs supported per channel \(\le\) Maximum number of ranks supported per channel \(\div\) Number of ranks per DIMM.

Notes: 1. The maximum number of DDR5 DIMMs supported is based on the dual-CPU configuration. The number is halved for the single-CPU configuration. 2. It indicates the maximum memory capacity supported when all the DIMM slots are populated with DDR5 DIMMs. The maximum DDR5 capacity varies with the CPU type. 3. DIMM Per Channel (DPC) is the number of DIMMs per memory channel. The information above is for reference only. Consult your local sales representative for details. 5.6.4 Population Rules General population rules for DDR5 DIMMs: • Install DIMMs only when the corresponding processor is installed. • Install dummies in the empty DIMM slots. 5.6.5 DIMM Slot Layout Up to 32 DDR5 DIMMs can be installed in a server, and a balanced DIMM configuration is recommended for optimal memory performance.

Notes: 1. Not all configurations support an operating temperature range of 5°C to 45°C (41°F to 113°F). The GPU configuration supports an operating temperature range of 10°C to 30°C (50°F to 86°F). 56 White Paper for KAYTUS KR2280V3 Series Servers Powered by Intel Processors 2. Standard operating temperature: - 10°C to 35°C (50°F to 95°F) is the standard operating temperature range at sea level. At the altitude of 0 to 3,048 m (0 to 10,000 ft), derate the maximum allowable temperature by 1°C per 305 m (1°F per 556 ft). No direct sustained sunlight is permitted. The maximum temperature gradient is 20°C/h (36°F/h). Both the altitude and the maximum temperature gradient vary with server configurations. - Any fan failure or operations above 30°C (86°F) may lead to system performance degradation. 3. Expanded operating temperature: - For some configurations, the supported system inlet ambient temperature can be expanded to 5°C to 10°C (41°F to 50°F) and 35°C to 40°C (95°F to 104°F) at sea level. At an altitude of 0 to 950 m (0 to 3,117 ft), derate the maximum allowable operating temperature by 1°C per 305 m (1°F per 556 ft).
