## Questions & Answers

**Q: Hi. is the "crucial ct16g4sfd8266 16 gb " compatible with pavilion 14-ce2068st?**
A: It was for my pavillion. Just buy ram with speeds the same or slower than what you have at the momment. Check your ram speed using the bios

**Q: Hi. is this ram fit to hp omen 15 ax- 009na ?**
A: If you're unfamiliar with the specifications, Crucial has a tool on their website that will tell you what is compatible with your exact machine.  Of course, you don't need to use their own brand, but I've happily been Crucial for upgrades for over 15 years.

**Q: Does this work in an dell xps 15 9560 model laptop**
A: Check with the Crucial UK website. That will tell you the answer

**Q: Will this work on a Msi gs75 stealth 8se gaming laptop?**
A: If you go to cruscials website and put in your laptop model it will list the memory that they guarantee to be compatible. That easy way to make sure. Remember the max ram you can have in your laptop is 32gb so keep that in mind and make sure you don't have that much already. Mine had 8gb so I added the 16 to give 24gb. But that was more do to other reasons than doing best thing. For reference I have a MSI GL75 9sd and this ram works perfectly. And this ram is correct type and speed for your machine but best to check for yourself be going to crucial compatibility site or on the MSI site for specs. Rather than just listening to random dude on here.
