Which memory configuration is possible?

Our memory team will be happy to help you choose the right memory and configure your server.

Principles of memory assembly

  • Höhere memoryfrequenzen passen sich ggf. anderen memorytaktungen in der Systemumgebung an and unterstützen entsprechend langsamere Taktraten

  • The low voltage memories with 1.35V are clocked with 1.5V when mixed with 1.5V memories via the fallback option in the memory. 

Memory configuration for good system performance

  • Verteilen Sie die memory gleichmäßig auf die memorysteckplätze and gleichmäßig auf die CPUs
  • Wenn mehr als eine CPU vorhanden sind, sollten die memory pro CPU identisch (gespiegelt zur anderen CPU) bestückt werden.

FAQ - Frequently asked questions about Lenovo ThinkServer RD640

Which capacity does the factory installed memory of the Lenovo ThinkServer RD640 have?
The ThinkServer RD640 is supplied with 8GB RAM.
What is the maximum memory capacity of my Lenovo ThinkServer RD640?
The maximum memory size of the ThinkServer RD640 is 640GB / 320GB according to manufacturer.
The phs memory® option for my Lenovo ThinkServer RD640 is faster than the existing RAM - Is this a problem?
If your system is limited to a slower memory speed, the "Fallback Speed Setting" in the SPD of the phs memory® RAM-Modules ensures the support of slower memory settings down to the given memory speed.
Why is the maximum RAM amount of phs memory® for ThinkServer RD640 higher than the maximum RAM limit listed by Lenovo?
The Lenovo ThinkServer RD640 can be upgrade to a maximum memory capacity of 640GB / 320GB according to manufacturer. This is more than Lenovo has listed in their technical specification. There are different reasons, why more memory is possible:
- improved production processes in the memory technology enable higher memory capacities
- new BIOS-Version support higher memory capacities
- the information of the Lenovo datasheet concerning the maximum RAM amount for the ThinkServer RD640 is not up to date.
- we tested and verified the higher memory limit in our overRAMing project.
