## Questions & Answers

**Q: Is this a 8gb or 16Gb module. The title says 16 but the technical details say 8. Which is it?**
A: The one I ordered and received was the single 16 gb stick

**Q: Is this a 16gb ddr4 single stick?**
A: Yes, this is a single stick memory card.

**Q: is this compatible with T 40 dell server?**
A: I dont know, I believe that it would be compatible with many different current mother boards.  There are probably some on line forums that may have a better answer.  I just build my system as a stand alone game computer to run MS Flight Simulator.  
Basics are 2 NVIDIA 1650 GeForce graphicas cards, a Samsung 970 1 Terabyte SSD drive, Interl Core 17 9th GEN processor and an 850 watt EVGA GQ power supply.  Hope this helps.

**Q: Will this work for intel xeon processor w-2295 - with dell precision tower 5820?**
A: I thought the Intel Xeon processors required ECC (error correcting) memory modules. These are non-ECC - I don't think these will work for you. I would "Google" Intel Xeon W-2295 memory module and see if it will advise the recommended memory or contact customer service at a memory supplier like Crucial Memory website and load their memory identifier program (it's free and harmless to your computer) and see if it will make a recommendation. Hope this helps.

*by S***N on 7 December 2019*

Recommended RAM for Dell XPS 8930. Dell limits the memory’s speed to 2666mhz. This is the fastest OEM recommended stick for the Dell XPS 8930 machine. Many sticks that have a higher rated speed actually have a low native speed (2133mhz) but are overclocked. The dell XPS 8930 will only recognize the native speed. This is the fastest memory I can buy and works flawlessly with my Dell XPS 8930. It’s also cheap.
