Product Description
Will this work in my desktop computer?
No, this memory is designed for servers and select workstations that support DDR4 ECC Registered memory only. If youโre unsure, contact our support team, weโre happy to help you find the exact memory your system needs!
Whatโs the difference between DDR4 and other types of memory and can I use them interchangeably?
No, DDR4 memory is not compatible or interchangeable with other types such as DDR5, DDR3, and so on. Each memory type uses different slot designs, voltages, and architectures, so your system must support the memory type specifically.
Can I mix ECC Registered (ECC RDIMM) modules with other ECC types?
No, you cannot mix ECC Registered with ECC Unbuffered (ECC UDIMM), Load-Reduced (LRDIMM), or Non-ECC Unbuffered (Non-ECC UDIMM) modules. All installed memory modules must be the same ECC type or your system will fail to boot.
What ECC type does my system need and which slots should I use?
Refer to your system or motherboard manual for supported ECC types and correct memory channel configuration. Using the wrong type or incorrect slot population can cause boot failures or reduce system stability.
Why isn’t my memory running at the advertised speed?
Memory speed can drop when more DIMMs are installed per channel due to increased electrical load. This is normal and can vary based on your systemโs design. Check your serverโs memory population and configuration rules for optimal performance.

Customers say
Customers find the RAM works well with Dell T440 servers and appreciate its value as server memory. The product is easy to install, with one customer noting it slots in and boots without issues, and they report no stability problems during rendering or gaming. They like the memory capacity, with one mentioning it passes BIOS validation, and consider it an effective upgrade, particularly for Dell 5820 systems.
