Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3000MHz C15 Desktop Memory Kit - Black (CMK16GX4M2B3000C15)

Excelent product

At first, I bought and installed a Crucial 16GB Single DDR4 UDIMM CL17 memory into my new MSI X470 Gaming Plus motherboard with Ryzen 5 CPU. Im experienced with building PCs from scratch, been my hobby since college. When I started the computer for the first time, it would not post or allow me to go into BIOS, and gave out 3 long beeps. Online search found that its a memory not detected, or faulty. I dont think its a bad motherboard because Ive never had a motherboard fail, but Ive had lots of memory cards that did fail even when new. If cheap components are used in a memory card, it will have lots of quality and compatibility issues. After trying to re-seat the 16GB card many times, it finally worked without explanation. In BIOS, I wasnt able to enable my motherboards XMP to adjust memory speed or settings (all XMP settings were locked out). After running it for a few hours, I shut the PC down to install a new CD-Rom. Then when I turn my PC on, again would not post or allow me to go into BIOS, gave three long beeps, memory issue again. I finally gave up on the Crucial 16GB card and bought a premium gaming memory, CORSAIR 16GB (8GB x 2) Vengeance LPX, CL15, 3000 Mhz. After installing the Corsair memory cards, the computer booted fine the first time, and booted up twice as fast into Windows 10. My first guess is the Crucial memory cards are defective or has compatibility issues. My second guess is the CL17 of the Crucial memory is too slow for the Ryzen 5 2nd gen CPU and motherboard, and Ryzen 5 needs memory cards rated at CL15 and CL16 or faster (the lower the CL the faster the memory). Funny thing is after I purchased the Corsair Vengeance, as I was waiting for it to ship to my house, the Crucial 16GB was working again, computer was able to boot up. Its as if it knows the Crucial memory is getting replaced and it decided to work again. After installing the Corsair Vengeance cards, the default speed was at 2100 Mhz, without XMP configuration. I went into the Bios, enabled A-XMP, set it to profile 2, and its now operating at 2933 Mhz, close to the advertised speed of 3000 Mhz! Very happy with the Corasir Vengeance memory cards ($110 at time of purchase) even though it was $11 more than the Crucial card.

Cool product but make sure you know exactly what you are doing before you put the ram stick in. I learnt it the hard way when the PC would not turn on and I had to rebuild my entire computer.

Had manufacturer errors out of the box but discovered it too late after the return period. I advice to test your ram as fast as possible.

Takes 10 secs to install and runs great

problems with first set keep crashing. bought a second set and it works fine so far

I was very nervous this wouldnt work with my dell optiplex but I was very happy to find out it was one of the few upgrades my motherboard could handle and it upped my PCs performance very much! Thank you corsair!

Excellent product and quality

GREAT ITEM. RECOMMENDED!!!

Cant go wrong with Corsair RAM. Highly recommend.
