Is mixing these two types of RAM acceptable?

Series, voltage, and speed all seem to be the same, and the only difference is timing and latency.

Is it likely that I would run into any issues if I install the new RAM?

How much will performance suffer due to changes in latency and timing?


Thank you very much for reading

Absolutely do NOT mix those up. Multiple sticks should have the exact same specifications, SPECIALLY timing and latency, in order to work properly.

Your performance will suffer to the point your computer probably won't even boot for the MB not handling the memory.

If you want to add up memory, look for the very same model you currently have
