## Questions & Answers

**Q: This  compatible hpe micro server gen 10  plus , cpu xeon e-2224?**
A: This memory will not compatible with Hpe micro server Gen 10 plus, cpu seon e-2224. Based on the specs . This server required only 2 slots of memory 8gb-ddr4-pc4-2666v. Total required 2 of 8gb=16gb. However this list is 32gb for 1 pc.  Therefore, it will not fit with your server. I hope to answer your question. If you want to look for memory go to my amazon store  and search for retail-it-bayarea. that is my id username.
thanks
