Collection: Dell PowerEdge R805 RAM Memory Upgrades

Dell PowerEdge R805 Memory Configuration

The R805 is a Dual Processor system with 8 DIMM slots per CPU. There are two memory channels per CPU. Each memory channel manages 2 DIMM slots. 

Cloud Ninjas' Dell PowerEdge R805 Memory Upgrade Tips

• The memory interface of the PowerEdge R805 uses sets of 512MB, 1GB, 2GB, 4GB, or 8GB DDR2 registered DIMMS (RDIMM).
• The PowerEdge R805 supports up to 128GB of memory (16 x 8GB RDIMMs)
• Single- or dual-ranked modules are supported with the PowerEdge R805 (quadranked modules are not supported)
• The PowerEdge R805 supports 667MHz registered DDR2 memory modules (DIMMs).
• Think Long Term! Purchase the maximum amount that your PowerEdge R805 can hold and avoid wasting time and money on modules you won't be able to use if you upgrade again.
• The total number of memory modules that you should have in your PowerEdge R805 should equal 4, 8, and 16. To properly configure your system, install a minimum of four memory modules first.

Cloud Ninjas' Dell PowerEdge R805 Questions & Answers

1. What sizes modules can you use for the Dell PowerEdge R805 Server?
   This is a tricky question.  The Dell PowerEdge R805 can use 512MB, 1GB, 2GB, 4GB, and 8GB.  Buy your 128GB upgrades kits for your Dell R805 second generation server from Cloud Ninjas.
   
   
2. What speeds are supported by the Dell PowerEdge R805 Server?
   The Dell PowerEdge R805 Server can support 667MT/s single, dual, and quad rank DIMM.
   
   
3. What types of RAM are accepted by the Dell PowerEdge R805 Server?
   The Dell PowerEdge R805 Server supports DDR3 ECC Registered RDIMM only.  Unfortunately ECC Unbuffered and Load Reduced DIMMs are not compatible with the Dell R805.
   
   
4. What is ECC Registered Memory?  Is ECC Reg supported by the Dell R805?
   Yes.  The Dell PowerEdge R805 Server supports registered memory with ECC. ECC memory detects and corrects memory errors within the server environment. Registered (also called buffered) memory modules register between DRAM modules and the system's memory controller. ECC Registered Memory transfers less electrical load to your memory controller which makes it more stable and reliable.
   
   
5. What is Unbuffered Memory?  Is it compatible with the R805 server?
   No.  The Dell PowerEdge R805 Server does not support unbuffered memory with ECC. Unbuffered memory is memory that has no register between your DRAM and your system’s memory controller.
   
   
6. What is Load Reduced Memory and is it compatible with the Dell R805 server?
   No.  The Dell PowerEdge R805 Server does not support load reduced DIMM (LRDIMM). Load reduced DIMM is designed with a buffer chip (or chips) to replace the register to help minimize loading, the LRDIMM increases server system memory capacity and speed.
   
   
7. Can I mix ECC Reg with ECC unbuffered inside the R805?
   No. The Dell PowerEdge R805 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 max configuration for the Dell R805 server?
   Similar to above, this is tricky question.  The Dell PowerEdge R805 server allows the standard maximum configuration of up to 128GB GB via 16 x 8GB ECC Registered RDIMM memory. Buy your 128GB memory upgrade kits from Cloud Ninjas.
   
   
9. How many memory channels per CPU are there for the Dell PowerEdge R805?
   The Dell PowerEdge R805 Server has all DIMM slots directly on the motherboard, so there are no memory risers.
   
   
10. How do I identify the start of the memory channel for my R805?
    The start of each memory channel is color coded with a white DIMM slot.  A is the first channel.  B is the second channel.  C is the third channel and so forth.  The Dell PowerEdge R805 Server memory must be installed based on the number of processors. For example, DIMM A1–A8 corresponds to CPU1, DIMM B1–B8 corresponds to CPU2. With two processors and 2 FlexMem Bridges, DIMM C1– C8 will associate with CPU1, and DIMM D1–D8 will associate with CPU2.
    
    
11. Where can I order memory for my Dell R805 server?
    Order your memory right her from Cloud Ninjas by finding and selecting the memory package that is right for you.  Contact our sales team if you have any questions or prefer another method.
    
    
12. How soon will my RAM for my R805 server 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 Dell R805 server memory?
    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 Dell system. However, it will not have a Dell sticker. We ship major brands such as Samsung, Hynix and Micron.
