When purchasing new memory it is best to purchase identical memory modules to what your system already has. Your current Server configuration will determine the supported DIMM type and speed.
The Maximum amount of RAM the Lenovo ThinkServer RD640 Server can hold is 320GB ECC registered DDR3 memory.
Think Long Term! Purchase the maximum amount that your Lenovo ThinkServer RD640 can hold and avoid wasting time and money on modules you won't be able to use if you upgrade again.
The Lenovo ThinkServer RD640 supports maximum speeds of 1333MT/s to 1600MT/s depending on processor generation and how many DIMMs are used per channel.
Cloud Ninjas's Lenovo ThinkServer RD640 Q&A
1. What sizes can you use for the Lenovo ThinkServer RD640 Server? The Lenovo ThinkServer RD640 Server can be upgraded using 2GB, 4GB, 8GB, 16GB ECC registered DDR3 memory. Get your kit at https://cloudninjas.com/.
2. What speeds are supported by the Lenovo ThinkServer RD640 Server? The Lenovo ThinkServer RD640 Server can support memory modules at speeds of 1333MT/s to 1600MT/s depending on processor generation and how many DIMMs are used per channel.
3. What types of RAM are accepted by the Lenovo ThinkServer RD640 Server? The Lenovo ThinkServer RD640 Server supports ECC registered DDR3 memory.
4. What is ECC Registered Memory? The Lenovo ThinkServer RD640 Server supports registered memory with ECC. ECC Registered Memory detects and corrects single-bit errors in memory using parity bits and a series of mathematical equations. In ECC Registered memory, Registers (also called buffers) sit between the memory module's address bus and the physical memory chips.
5. What is Unbuffered Memory? The Lenovo ThinkServer RD640 Server does not support unbuffered memory with ECC. Unbuffered memory is memory that has no registers (also called buffers). Unbuffered memory can be ECC (for entry-level servers and Servers) or Non-ECC (for desktops and laptops).
6. What is Load Reduced Memory? The Lenovo ThinkServer RD640 Server does not suppport load reduced DIMM (LRDIMM). ECC Load Reduced Memory detects and corrects single-bit errors in memory using parity bits and a series of mathematical equations and reduces electrical load on the system's memory controller when compared to other types of memory modules. In ECC Load Reduced memory, Registers (also called buffers) sit between the memory module's address bus and the physical memory chips. Additional registers also sit between the Memory chips and the data bus, further reducing load on the system's memory controller in comparison to ECC registered memory.
7. Can I mix ECC Reg with ECC unbuffered or Non-ECC memory? The Lenovo ThinkServer RD640 Server does not support the use of both unregistered and registered memory with ECC or the use of non-ECC memory. It is recommended to use identical memory configuration in all channels.
8. What is the max configuration? The Lenovo ThinkServer RD640 Server supports the standard maximum configuration of 320GB using 20x16GB RDIMMs. Get your kit at https://cloudninjas.com/
9. How many memory channels per CPU? The Lenovo ThinkServer RD640 Server has 8 channels which house 3 or 2 sockets per channel with a total of 20 sockets in the dual processor configuration. Processor 1 has 3 channels, each managing 3 slots. Processor 2 has 4 channels, each managing 2 slots.
10. How do I identify the start of the memory channel? The Lenovo ThinkServer RD640 Server, requires memory to be installed into the first white channel marked A1 for Processor 1, inserting in sequential order and then Processor 2 the first white channel marked B1.
11. Where can I order memory for my server? Order your memory at https://cloudninjas.com/ by finding and selecting the memory package that is right for you.
12. How soon will my RAM arrive?Orders placed before 8 am are set for same day processing and shipping. Delivery times vary based on carrier and location.
13. What is the warranty on memory for the server?Cloud Ninjas offers a one-year warranty on fully tested, refurbished memory.
14. Is this RAM Dell labeled or Dell branded?No. The memory shipped from Cloud Ninjas is compatible with your Lenovo system. However, it will not have a Dell sticker. We ship major brands such as Samsung, Hynix and Micron.
