I thought it would be better 9/24/2020 9:25:29 PM

Pros: Easy to install I guess..?

Cons: Cheap, no heat sink covers, just a sticker. Had to set manual setup mem speeds for AMD chip.
Purchased in May, 1 stick died in August and the other died 6 weeks later. Kept failing in mem95 scan
Had to buy different memory.

Overall Review: I went super cheap, so maybe that's my fault but I've had nothing but bad luck with G.Skill.

No issues, but fake heat shields... 9/24/2020 8:54:52 PM

Pros: Gskill reliability

Cons: Didn't realize when I ordered these that the "heat shields" are just stickers... if I knew I would've spent a few extra $ to get real ones lol but not a super big deal.. still runs great in a gaming PC whether or not it looks fancy

Overall Review: Have bought G Skill since they started, have never received a DOA stick

Good ram 9/21/2020 2:12:56 PM

Overall Review: Running at 3200 OC on my ryzen motherboard. Had to reconfigure previous ram position before reading the slot, might be because of an compatibility issue with current ram settings. When I rebooted my pc and it worked fine as expected. Got it on sale which was a bonus.

Great option 9/21/2020 8:55:34 AM

Pros: it bumps right up to the listed speed without issues, and I haven’t had any problems with it so far

Cons: There’s no fancy heatspreader if you’re into that, the decal is only a sticker

Overall Review: This is an excellent choice if you need some ram to complete your build and are on a budget, after at least 6 months of owning it I haven’t had any issues with it and it performs exactly as described

Dead on Arrival 9/20/2020 5:54:05 PM

Overall Review: Stick came dead. Tried on B450 and X570 motherboards with no luck. My current DDR4 16GB 3200 Mhz boots up the PCs fine. Sent the stick back and got a refund.

Works Great! 9/17/2020 7:45:48 PM

Pros: Works great!

Cons: None!

Overall Review: This RAM works great with my other 2 DDR4-2133 RAM sticks for my ASRock ATX Motherboard (B450 Gaming K4). I thought something was wrong with my motherboard but for some reason, 2133 won't work with 2400 RAM anymore.
