Easy to install, worked right out of the ESD bag. IMO those having issues installing them do not know how to install SODIMMS. A note to others who are considering this ensure you have the correct model number of your printer, as this can make a big difference with what upgrades you can install. Other than that this module works flawlessly large files and PDFs do not stall anymore.

Our HP M451dw displays two question marks and a red light after installation of this memory. It's either faulty, or not compatible with this printer. The only solution was to remove the memory and do a hard reset of the printer.

This is the second printer I bought and added memory and it’s been perfect

It made no difference in printing speeds. Disappointed but really it's HP's fault not the memory. The memory is recognized by the HP Printer.

Well I had this printer for some time and I forgot that the system memory could be upgraded. Easy install and works, why the printer did not come with this .....is a problem, I don't recall there being any options in the queue to deal with ram. In the end...this card does work and install is a 5 min job.

This is generic memory for my laser printer. It works perfectly. I don't know what it says about this particular product as it's the first and likely only memory upgrade I will buy for the printer, but it was cheaper than others and is recognized by my printer. After installation I was able to print some documents that I couldn't before.

Showed up in a few days. Plugged into my HP M451dn color laser printer with no drama. Restarted the printer and everything works normal. Can't say exactly how much better the printer works now, but larger files "seem" to print faster, but not "oh-my-goodness-that-changed-everything" faster. For less than $20, it was worth it.

Absolute junk - installation of this RAM "upgrade" does nothing more than immediately cause my HP LaserJet Pro 400 M451dn printer to crash and completely shut down. Removal of this upgrade card restores the printer to normal functionality.

I wanted to upgrade the memory for my HP colour laser printer. After market memory modules are not cheap to buy and I needed a specific module. However, I found the exact item I needed at Amazon Canada at an excellent price. It arrived a day earlier than promised and works fine in my printer.
