Hp all in one ram upgrade

[5Too]

I'm sure this will be considered one of those novice questions-and I am sure the answer is simple but here goes.

I just bought an HP 22-b013w, my last computer/laptop was the HP 2000 so perhaps that explains how ancient I am.

I'd like to upgrade to 8GB and a youtube video shows how simple that process really is, but my question is can I buy a singular 8GB of memory or do I have to buy 2x4gb?  Also, I have done searches for ram memory that exactly matches the following for my computer  DDR3 PC3-12800 SODIMM (204-Pin,1600mhz), Non ECC Unbuffered 1.35V/1.5V CL11 . Is there an reason why ram may not work on my HP? Thank you for all your assistance

The HP info page lists the following

• Dual channel memory architecture
• Two DDR3L SODIMM (204-pin) sockets
• Supports up to PC3L-12800 (DDR3L-1600)
• Supports 4 GB and 8 GB DDR3L SODIMMs
• Supports up to 4 GB on 32-bit systems

@5Too,

Welcome to our HP Community forum!

Your HP All-in-One - 22-b013w (V8P50AA) can be upgraded up to 2x4GB of DDR3 PC3L-12800, 1600 MHz, Non-ECC, SODIMM, 204-pin RAM sticks, such as this quality/affordable Amazon purchase option: https://www.amazon.com/Timetec-2x4GB-DDR3L-DDR3-1600MHz/dp/B0145V6NKU/ref=sr_1_1?crid=1PYAHOR8MXDHF&....

Yes, you have to buy 2x4GB RAM sticks, as your AIO may not be compatible with one 8GB RAM stick -at least, that is what I would do.
