## Questions & Answers

**Q: Will this work in my desktop computer?**
A: No, most desktop PCs do not support ECC memory and instead require Non-ECC memory. This memory is designed for workstations and servers compatible with DDR4 ECC Unbuffered memory. If you’re unsure, contact our support team, we’re happy to help!

**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 Unbuffered (ECC UDIMM) modules with other ECC types?**
A: No, you cannot mix ECC Unbuffered with ECC Registered (RDIMM), 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.
