I have an HP s01 (the 10th gen celeron model I dont remember the specific model) that I host plex off of. I wanted more ram for it. I chose a 16gb stick of ram because the max it can hold is 32gbs. This worked. And I can buy a second one some day if I want to max out my ram. For now I have 20gb of ram.

My new Dell Inspiron 3880 desktop computer only had 4 GB of memory and has a hard disk drive, not a solid state drive. A hard disk drive can greatly slow a computer because it is not random access but must physically move a read/write head for each data segment. Having adequate memory to load applications and data into fast memory can greatly increase the effective speed. The Inspiron 3880 case is easy to open with a couple of thumb screws and replacing the 4 GB memory card with the Crucial 16 GB memory card was easy.

It was easy to fit the rams. They work perfectly fine. The communication with Crucial sales team was seamless and easy. I would recommend this product and this company to my my friends. I will order again when suitable.
Plan on buying 3 more to fill out my new Asus TUF mb. Been using Micron memory for 20 years. Never had one go bad. Lost a half dozen Corsair Vengeance sticks in the last 3 years.
Pros: Arrived quickly, fitted perfectly and immediately recognised by my PCCons: I can't see any noticeable difference but then I am not a gamer. I may have been better off installing two of half the size to keep my system in balance.
From 8GB to 24GB RAM and I noticed the difference INSTANTLY. I bought the 16GB and then mixed it with my HP Pavilion-gaming-tg01-2170m's old RAM and there wasn't a single issue. My computer now runs faster and is farrrr more fit for gaming than it was before. Looking forward to upgrade the RAM again as well as the SSD.
Ive been buying Crucial memorry for past 10+ years, always dependable. Cant recommend highly enough.
Can always buy from Crucial.com with ease, and peace of mind knowing you are getting the correct RAM Memory for your particular system. Been buying RAM from Crucial for many more and never disappointed
i have used crucial products for a few years now. it's a good way to extend the life of my computers and make them work faster.The scan tool shows me what will work with my items.
