## Questions & Answers

**Q: Will this work in my desktop computer?**
A: No, this memory is designed for servers and select workstations that support DDR4 ECC Registered memory only. If you’re unsure, contact our support team, we’re happy to help you find the exact memory your system needs!

**Q: What’s the difference between DDR4 and other types of memory and can I use them interchangeably?**
A: 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.

**Q: Can I mix ECC Registered (ECC RDIMM) modules with other ECC types?**
A: 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.

**Q: What ECC type does my system need and which slots should I use?**
A: 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.

**Q: Why isn't my memory running at the advertised speed?**
A: 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 system’s design. Check your server’s memory population and configuration rules for optimal performance.
