Is timing and latency is critical when buying RAM?

Hi all.

I just bought a HP - Pavilion HPE - h8-1234 PC and want to buy more RAM.

I know I need 240 pin DIMM PC3 - 12800 DDR3 - 1600, but I see a lot of times sellers will list timing and latency.

As latency case: 8 and Timing: 8-8-8-24

I have read technical data online for the PC as well as information of available memory on the HP site but have not found anything that talks about timing RAM and latency.

I read a few forum posts where people said they had to change the BIOS settings to get their PC to recognize their RAM due to a speed issue or because the system wouldn't start after they have installed more RAM.

I really don't want to have to dink with the BIOS.  I just want to buy something that will work with the existing system.

Please inform me.

Thank you

Don

Don,

This is a thorough article on the timings of the RAM. With single channel mode, the timings fall usually the lowest common denominator. Mode double channel, it may be OK to use a pair with a 'X' timing and the other with a timing 'Y', but it is not good practice, and can the opening questions. Alternatively, the system that they are the same and it can force all work. I didn't want to try it.
