Can I find the exact type of RAM without looking inside? [duplicate]
Go to Cruical.com and run their test. It will tell you.
You could alternatively use Speccy or some other alternative, there are plenty out there.
CPU-Z should display the RAM info for you. Have a look on the memory tab, there should be a drop down list containing entries for each slot you have.
Edit: Sorry, the drop down list is on the SPD tab.
