after two years
Size: 16GB Kit (8GBx2) Single Rank Style: 2600MHz Pattern Name: Memory
This memory is finally failing. Dont ignore the one star reviews. A lot of them say it's over after one year but I got mine in June of 2020. Not sure if a windows update messed this up but I started getting the blue screen bios error about memory. The diagnostics test are coming back clean but I'm sure once I replace the memory I'll be okay again. Found a high rated 32gb set for less than this I'm going for this time and it's a different brand. It's important to note I only have issues when running rcps3. Everything else still works like a charm cyberpunk gta5 Skyrim SE fallout.. but rcps3 is the most important thing I want good ram for lol. ... show more

Outstanding Value
Size: 16GB Style: 2600MHz Pattern Name: Memory
This RAM works very well. Just remember when buying RAM to look at manufacturers recommended speed for your CPU and your Motherboard. If they are not equal then install the slower of the two. It will ensure that your computer will work effectively.

Works as advertised
Size: 16GB Dual Rank Style: 2600MHz Pattern Name: Memory
Computer says “Hi RAM, welcome to the motherboard!” RAM replies, “It’s great to be here! I fit in so well!” They will live in harmony for years to come, unless the dreaded Dr. Surge shows up!

HP PAVILLION DESKTOP TP01
Size: 8GB Style: 2600MHz Pattern Name: Memory
PERFECT!!! If you have an HP Pavillion TP01-xxx desktop compuiter; let it be known that this Crucial DR4-2666 MH CL19 DESKTOP MEMORY CT8G4DFRA266 can be installed fairly quickly without having to take anything apart inside. It is a simple matter of putting an anti-static wristband on either wrist; connect the alligator clip to a metal part somewhere within reach of what you are doing. Remove the side cover and if this is not your first time doing this, you should have the computer back together with all your peripherals; mouse; keyboard any USB connectors; HDMI or other video connector to your monitor and be up and running in under 15 minutes. VERY simple. EXTREMELY IMPORTANT NOTE: Installation notes: a. DON'T FORGET THE ANTI-STATIC WRIST STRAP. Also, b. to be safe and not zap your new or old memory module; your motherboard or worse everything inside the casing rendering your PC completely useless: c. even with the wrist band on, to be on the safe side discharge any residual static electricty from yourself; ensure to touch some metal on the pc casing surface before touching anything inside the computer that has a microchip; and that the alligator clip is secure. d. MAKE SURE you are not using a screwdriver or anything else that might fall inside the casing and land on the motherboard or other sensitive component that has a magnetized end. A screwdriver with a magnetized end for example, won't be useful for anything except snagging a hard to get tiny screw or something. Then, except for getting that little screw that magnetized screwdriver end in this example could degauss, or demagnetize something you don't want degaused or demagnetized. As a result, you could very well find yourself holding 600 dollars or so worth of garbage instead of the computer you set out to upgrade. You DO want to upgrade, nopt down grade or degrade altogether, right? Okay. So careful not to have any magnets too close by within your work area while doing your upgrade. Finally, an anti-static wristband if you don't already know can be purchased for under 10 dollars or not much more than 5 or 6 dollars. That small extra amount of money could be the difference between being up and running quickly or without a PC. Don't start the uprade without one. If you are new to this or just haven't done an upgrade for awhile, don't forget someone told you so. I hope you see this and I hope this was helpful to you. ... show more
