Doubled the memory in my Acer Aspire E 15 E5-575-33BM (now up to 8GB). To tell the truth the laptop ran fine (no lag, average disk usage was already quite low with the default 4GB but bought anyway to reduce disk stress etc. I don't see much of a difference with the extra 4 GB noticed (other than that disk usage) now averages 0% when idle %) I haven't faced much memory stress yet (burning DVDs, running memory intensive games) Mostly just surfing the web (multiple websites open at once), streaming videos, etc. Works well, it's worth the money.
