Question

Iron

There is an HP Omen 15-ax219ur laptop. There is a desire to replace the RAM and add an SSD to the M2. Questions:
1. What is the frequency of the RAM in this laptop? At the office The site says 2400, AIDA shows 2133, HP Support Assistant shows 2600. It's not clear what to buy so that it fits exactly.
2. What interface should the SSD have (PCI-E x4 / SATA III)?
Tell me please.

Answer 1

1. AIDA shows the frequency of the RAM you currently have. If you plan to replace the entire RAM in the laptop with new sticks, then you can put 2400 (this is the maximum supported by the i7-7700HQ). If you want to add one bar to the one you have, then even if you buy a second 2400, they will work at 2133, since pairing is possible only at one frequency and the minimum is selected.
2. PCI-E x4, then you need to take 960 samsung M2!
