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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It worked on install. 🔥 *by T***N on June 22, 2025* Why did you pick this product vs others?:It was largest stable ram choice for my dual cpu multi gpu computer ,from a noted producer.Ease of installation:Super easy.Memory upgrade:256gb over 64 total and mixed which is bad.Memory quality:above boardSpeed:above boardPerformance:Above board Compatibility:Worked perfectly for my Machinist x99 dual cpu mobo ### ⭐⭐⭐⭐⭐ The best upgrade for a Dell 5820! *by T***N on February 6, 2025* Bought four kits and they work like a charm. Easy installation and a quick upgrade. Huge value for the money spent. Speed, Stability and Memory capacity is perfect. Nothing on the outside of the computer tells how great it looks inside. ### ⭐⭐⭐⭐⭐ Works as expected *by N***7 on June 20, 2025* Initial review after 1 hour. Will update if anything changes.Bought A-Tech kit containing two 16GB 3200MHz ECC modules for Dell Precision 5820 workstation with Xeon W-2223 cpu. Existing ECC memory are two 8GB modules supplied by Dell: each 8GB module is a Micron part rated at 3200MHz but the 5820 runs them at 2666MHz system memory. The manual does not document mixing 8GB with 16GB modules but I wanted 48GB total. I kept the two 8GB in DIMM1 and DIMM2, and finally added the two 16GB in DIMM3 and DIMM4. The motherboard has the physical slots out of order with the DIMMx numbering so pay attention (initially I put the 16GB modules in DIMM5 and DIMM6 but my test application ran ~20% slower than final DIMM3 and DIMM4 locations). Make sure the side cover is back in place before booting the Dell 5820. The BIOS picked up the memory had changed and then booted into my OS. All good - Ubuntu 22.04 OS shows 48GB RAM available. Good product. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/745449224-64gb-kit-8x8gb-ddr4-2133mhz-pc4-17000-ecc-rdimm-1rx4](https://www.desertcart.vu/products/745449224-64gb-kit-8x8gb-ddr4-2133mhz-pc4-17000-ecc-rdimm-1rx4) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
