Collection: IBM X3250 M4 Memory Upgrades

IBM X3250 M4 Memory Configuration Guide

The X3250 M4 is a Single Processor system with 4 DIMM slots. There are two memory channels total. Each memory channel manages two DIMM slots. The X3250 M4 supports the use of ECC unbuffered memory as well as standard voltage (1.5v) and low voltage (1.35v) modules. You cannot mix different memory types and voltages. Different speeds may be mixed, however they will operate at the speed of the slowest modules installed. We recommend all the memory inside your IBM X3250 M4 be matching modules. We have this in mind, by shipping only matching kits. This ensures stability and makes sure that your system will function with no issues.

Cloud Ninjas' IBM X3250 M4 Memory Upgrade Tips

• There are a total of 4 DDR3 DIMM slots in the IBM X3250 M4.
• Speeds supported: 1333MT/s and 1600MT/s. Please note that speeds of 1866MT/s will clock down to the true fastest speed of 1600MT/s.
• Sizes supported: 1GB, 2GB 4GB, and 8GB ECC unbuffered modules.
• Both low voltage (1.35V) (PC3L) and standard voltage (1.5V) (PC3) are supported.  
• DO NOT MIX DIFFERENT MEMORY TYPES.
• The X3250 M4 maxes out at 32GB using ECC unbuffered memory.
• The X3250 M4 has only one CPU, two memory channels, with two DIMM slots per channel.
• Think Long Term! Purchase the maximum amount that your IBM X3250 M4 can hold and avoid wasting time and money on modules you won't be able to use if you upgrade again.

Cloud Ninjas' IBM X3250 M4 Questions & Answers

1. What sizes can you use for the IBM X3250 M4 Server?
   The IBM X3250 M4 can be upgraded using 1GB, 2GB, 4GB, 8GB ECC unbuffered modules.
   
   
2. What speeds are supported by the IBM X3250 M4 Server?
   The IBM X3250 M4 Server can support memory speeds of 1333MT/s and 1600MT/s. 1866MT/s can be used, but will unfortunately clock down to 1600MT/s
   
   
3. What types of RAM are accepted by the IBM X3250 M4 Server?
   The IBM X3250 M4 server supports ECC Unbuffered modules.
   
   
4. What is ECC Registered Memory?
   ECC memory has the ability to fix memory errors in your server system. Registered (also called buffered) memory modules register between DRAM modules and the system's memory controller. ECC Registered Memory relieves stress off of the memory controller by decreasing the electrical load which increases its stability. The IBM X3250 M4 server does not support ECC Registered memory.
   
   
5. What is Unbuffered Memory?
   Unbuffered memory has no register between the DRAM and the system’s memory controller. Unbuffered memory can be more efficient than registered memory since there is a direction connection from the DRAM to the memory controller. The IBM X3250 M4 supports unbuffered memory with ECC. 
   
   
6. What is Load Reduced Memory?
   Load reduced memory (LRDIMM) modules are designed with a buffer chip (or chips) to replace the register to help minimize loading. the LRDIMM increases server system memory capacity and speed. The IBM X3250 M4 Server does not support load reduced memory.
   
   
7. Can I mix ECC Reg with ECC unbuffered or Non-ECC memory?
   It is never recommended to mix different memory types. Mixing unbuffered memory with ECC and non-ECC memory may cause boot failure. The use of both unbuffered and registered memory is never recommended. It is best practice to use identical memory configuration in all channels.
   
   
8. What is max configuration?
   The Dell PowerEdge R720 Server allows the maximum memory configuration of up to 32GB using ECC unbuffered modules.
   
   
9. How many memory channels per CPU?
   The IBM X3250 M4 Server has 2 memory channels and each channel operates 2 DIMM slots.
   
   
10. How do I identify the start of the memory channel?
    Each DIMM slot in the IBM X3250 M$ is color coded blue and black. The blue slots represent the start of a channel.
    
    
11. Where can I order memory for my server?
    Order your memory right here on this page by finding and selecting the memory kit that is right for you.  Or if you prefer another method, then please email sales@cloudninjas.com.  Our team of ninjas is here to help make your buying experience as easy and smooth as possible.
    
    
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.
