    Bought as an upgrade for my laptop MSI GL75 9SDKStarted working right after installation without any tuning.CPU-Z shows full match to the described characteristics. Dual-channel mode just works.The system looks to be pretty stable and fast.Wrt performance it's probably better to buy a smaller volume bars which may come with smaller timings, but 19 is already pretty good IMO. I any case I've bought this pack to have enough volume but not enough speed, and I've got exactly what was expecting.Maybe except the price which taking account the shipment and import clearance taxes turned out to be higher than from local retailers (overall local Belarus prices are 14% cheaper for the same memory)If anyone curious there is dmidecode below: Array Handle: 0x003A Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 32 GB Form Factor: SODIMM Set: None Locator: ChannelB-DIMM0 Bank Locator: BANK 2 Type: DDR4 Type Detail: Synchronous Speed: 2667 MT/s Manufacturer: Micron Serial Number: 2F3A12AE Asset Tag: 9876543210 Part Number: 16ATF4G64HZ-2G6B4 Rank: 2 Configured Memory Speed: 2667 MT/s Minimum Voltage: 1.2 V Maximum Voltage: 1.2 V Configured Voltage: 1.2 V Memory Technology: DRAM Memory Operating Mode Capability: Volatile memory Firmware Version: Not Specified Module Manufacturer ID: Bank 1, Hex 0x2C Module Product ID: Unknown Memory Subsystem Controller Manufacturer ID: Unknown Memory Subsystem Controller Product ID: Unknown Non-Volatile Size: None Volatile Size: 32767 MB Cache Size: None Logical Size: None

    Reviewed in Brazil on March 10, 2024
    Comprei um memória de 16GB para expandir a memória total do meu laptop pra 24GB. Fiz uma pesquisa extensa antes para saber quais as melhores marcas de memória RAM, e a Crucial foi uma das principais recomendações. Tem três semanas que meu laptop está rodando com a memória nova, e consigo usar máquina virtual, rodar programas da Adobe e jogar jogos tranquilamente. Super recomendo!

    A instalação no slot foi bem simples de fazer, porém encontrei um problema com o Windows, que se recusava a incializar após eu inserir a memória nova. Fui descobrir que era uma reclamação de paridade do próprio Windows mesmo, pois os slots de RAM do meu laptop estavam com 16 x 8, e o recomendado é sempre ser duas memórias de capacidades iguals, 8x8, 16x16, etc. Após configurar o Windows para aceitar a configuração 16x8, ele inicializou normalmente, e desde então, não tive mais problemas.
