CORSAIR Vengeance Performance 16GB (2 x 8GB) 260-Pin DDR4 SO-DIMM DDR4 3000 (PC4 24000) Memory (Notebook Memory) Model CMSX16GX4M2A3000C16

Pros: Got 3000MHz Timing 16-18-18-39-524-1T

Cons: none so far You will need XMP option in your laptop's BIOS. Without this option, you will need a unlocked BIOS! I can only recommend people who knows how to run things like command and DOS to buy this kit. You will need to write and flash BIOS ROM. Not simply update it.

Overall Review: Good for me so far!!!

Pros: -Decent speeds & timings IF you're laptop has access to XMP

Cons: -False advertising. Requires XMP

Overall Review: Default speed is 2666 without XMP. The product SPECIFICALLY says "Auto-overclocking (no BIOS configuration required)", and I even contacted corsair and they said the same thing. Unfortunately this is not true and requires XMP, but my HP motherboard does not allow XMP. I'm very computer savvy, including overclocking my Desktop PC's RAM. Some modules (like the default 3200 RAM in my HP ENVY x360) can run at their higher speeds without BIOS overclocking or XMP required. I verified through multiple programs that these sticks only run at 2666. I was not able to verify the timings. I did a few RAM tests which show them to run similarly to 3200 CL22, so I assume the timings are running decent at least. I'd probably stick to buying something cheaper unless you have XMP access.

Pros: Very easy to install!

Cons: Would like to see a buy back of used apple memory or trade in programs.

Overall Review: Four stars

Pros: None unless you only want 2 sticks and only 16GB. Giving one egg for that reason only. But, see cons because 2 sticks were not great either.

Cons: Bought two kits for 32GB and discovered they are programmed for 1 DIMM per channel. Machine makes no effort to POST unless only two sticks are installed. SPD also has checkum errors and the MAC address shows only the word "untested" for MAC status. Memtest86 returns errors with 2 sticks installed when tested with default 2666 profile.
