Lenovo ThinkServer RD530 - Manual (Page 87)

Notes:
• All memory modules to be installed on a server must be the same type (LV RDIMM, RDIMM, or UDIMM).
• When you install memory modules with different ranks in one channel, start from the farthest memory slot
in the channel and install the memory module that has the most ranks first.
• When 1.35 V memory modules and 1.50 V memory modules are installed into the memory slots for the
same microprocessor, all the memory modules run at 1.50 V.
• When memory modules with different frequencies are installed into the memory slots for the same
microprocessor, all the memory modules run at the lowest frequency.
• It is recommended that you install the low-voltage memory modules into the memory slots for the same
microprocessor to ensure low power consumption.
• It is recommended that you install the high-frequency memory modules into the memory slots for the
same microprocessor to ensure high performance.
