PNYPerformance 16GB DDR4 DRAM 2666MHz (PC4-21300) CL19 (Compatible with 2400MHz or 2133MHz) 1.2V Notebook/Laptop (SODIMM) Computer Memory RAM – MN16GSD42666

I have the Lenovo 4 flex pad Laptop with 4GB ram, running windows 10. Well most of the time it was using 3.9 GB of ram which made things sluggish and many time it needed like 6MB. And that will jam you up. So I saw this PNY (a brand which has treated me well over the years) for about the price of a Large Pepperoni Pizza. 16GB is the max the Lenovo can use and it only has the one port. I put it in and it instantly recognized and increased to 16GB. Things run fast and smooth now. One of the best improvements, especially cost wise. The deal with this upgrade however, is that you are not changing a lightbulb here, If you know much about computer repair not just hooking one up, maybe how to change spark plugs on a car or install a garage door opener, or especially if you used to put together those little plastic model kits, then maybe you can do this. It requires several small screws to be removed (smaller then a grain of rice), a heat shield plate removal, then a switch out of the module by unhinging retainer clips. So it's not the easiest thing, maybe watch a YouTube video on it first to see what you think about the difficulty level.

I have an MSI GF72VR 7RF which a baggage handler was kind enough to throw/step on/kick and break the bottom. The break oddly enough damaged the ram and caused a (A7) Me Downgrade - Request MeSpiLock Failed error. This really stumped me, thinking perhaps an xray damaged my bios. I ran a BIOS update via USB and that still did not work. A last ditch effort and I removed a single stick of RAM and my computer successfully booted both Ubuntu 22.05 and Windows 10.On a whim I ordered these and they would fine so far. My computer shows 32GB of RAM at least in Linux, and Windows gave a little hardware check because some things changed (I didn't verify Windows saw all the RAM, but I don't care what Windows sees). Very pleased to see this work with reverse compatibility.

Super fast upgrade from 16 GB to 64 GB for my Razor Blade 15 Advanced Late 2019 Model (rz09-03017)

I wanted to see if my Thinkpad X260 would recognize this 32GB RAM stick, and it does. Now I can run more virtual machines or Docker instances - great for my work and hobbies.

Received a 16 and an 8 chip module in the same package. I think this is done for some memory controllers to see both chips, however this has an adverse effect on others. The 16 chip module MUST go in the first slot! Do not go by proximity to the CPU, look up the specs. Anyway working fine in Dell 3050 I7-7700T.

For the most part, memory is memory. These modules fit. Works okay in a laptop, but will NOT work in a Terra-Master NAS which is what I needed it for. Not memory fault! Terra-Master OS will only recognize their products.

I purchased to add to my 16GB RAM. It's nice having 48GB RAM. Things working great so far!

Good memory it was fast and had no problems ,I ended up returning this stick because I returned the laptop I bought it for....they credited my account a day later and had no issues... good company!!

Finora ottima e devo dire che non ho apprezzato grandi miglioramenti installandola su un pc già con 8 giga di ram. Vedremo la durata. La consiglio se è in sconto visto che il prezzo sembra fin troppo "ballerino". Una stella alla confezione tutta di plastica e molto dura. Un impresa spacchettarla, più difficile che installarla!

Si quieres una memoria de buena velocidad y económica y sobre todo una buena marca, ésta es de la mejores opciones, para mi punto de vista PNY es muy buena marca con lo cual tendrás una garantía de calidad y rendimiento, velocidad de 2666 es mejor que revises la velocidad de tu memoria actual para poder sacarle mejor provecho, que ambas tengan la misma velocidad.

Llegó todo perfectamente bien, sin detalles, la instale rápidamente en mi laptop MSI que ya tenía 16 GB, al encender la reconoció de inmediato y ya tengo los 48 GB, va funcionando de maravilla a los 2666MHz

Great memory for the right price! Worked right out of the box. Haven't had any problems with it. Very reliable. No errors, no problems. Why pay more? Comparing it with the Samsung memory I took out, the design looks identical.

It was easy to install, and Windows recognized the additional memory. This product is compatible with the existing memory and reliable. I recommend this product.
