Cloud Ninjas's Dell PowerEdge R420 Q&A
1. What sizes can you use for the Dell PowerEdge R420 server? The Dell PowerEdge R420 server can be upgraded using 2GB, 4GB, 8GB, 16GB ECC Registered. Get your kit at https://cloudninjas.com/.
2. What speeds are supported by the Dell PowerEdge R420 server? The Dell PowerEdge R420 server can support memory modules at speeds 1600MT/s.
3. What types of RAM are accepted by the Dell PowerEdge R420 server? The Dell PowerEdge R420 server supports ECC Registered memory.
4. What is ECC Registered Memory? The Dell PowerEdge R420 server does support 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 Dell PowerEdge R420 server does not support unbuffered memory with ECC and Non-ECC. Unbuffered memory is memory that has no registers (also called buffers). Unbuffered memory can be ECC (for entry-level servers and workstations) or Non-ECC (for desktops and laptops).
6. What is Load Reduced Memory? The Dell PowerEdge R420 server does not support 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 Dell PowerEdge R420 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 Dell PowerEdge R420 server supports the standard maximum configuration of 192GB using 12x16GB ECC RDIMMs memory. Get your kit at https://cloudninjas.com/
9. How many memory channels per CPU? The Dell PowerEdge R420 server has 3 channels which house 2 sockets per channel with a total of 12 sockets in the dual processor configuration.
10. How do I identify the start of the memory channel? The Dell PowerEdge R420 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 labeled or Dell branded?No. The memory shipped from Cloud Ninjas is compatible with your Dell system. However, it will not have a Dell sticker. We ship major brands such as Samsung, Hynix and Micron.
