Hi, i know it mention backward compatibles in the data sheet,

but i had bad experience with RAM (kingston), where they said it works but unfortunately no. I had to try 3 different RAM to find the one that really works..

So just want to check if anyone really try this SSD.

Really appreciate any help. Really need new SSD to use Altair Inspire and Simsolid software.

    Hi adnansni

    💡 Predator G3-571 SSD Upgrade Advice — PCIe 5 & Gen4 Are Smarter Buys 💡

    If you’re upgrading your Predator Helios 300 G3-571-77QK, there's no need to overpay for legacy Gen3 SSDs. SSDs like the Samsung 970 EVO Plus still perform well but often cost more than newer PCIe Gen4 or even Gen5 drives, which run flawlessly at Gen3 speeds in these older laptops.

    🔧 Confirmed SSD Compatibility:

    • The G3-571 supports PCIe Gen3 x4 NVMe SSDs
    • Samsung 990 EVO Plus works great, even at reduced speeds (~3.5 GB/s max)
    • ⚠️ Gen4/Gen5 drives won’t reach full rated speeds but are better deals for performance per dollar

    🧊 Thermal Wrap Recommendation:

    • For the 990 EVO Plus 2TB, consider the ultra-thin EC360 Copper Thermal Sticker
    • It fits perfectly under the Helios M.2 cover and helps avoid throttling during long Altair Inspire or Simsolid sessions

    📛 RAM Mismatch Tip:If you’ve tried Kingston Fury Impact DDR4 RAM and had issues, it’s likely due to its XMP profile reverting to JEDEC at reduced speeds when BIOS doesn’t support XMP. Some laptop controllers won’t play nice with those fallback settings.

    💬 Forum Wisdom: Compatibility isn’t just specs — firmware behavior, thermal limits, and BIOS quirks all matter.

    your laptop supports M.2 NVMe SSDs, and users have successfully installed drives like the Samsung 970 EVO Plus, which is very similar in interface and form factor to the 990 EVO Plus. The 990 EVO Plus uses a PCIe Gen 4x4 interface, but it’s backward compatible with PCIe Gen 3x4 slots — it will simply run at Gen 3 speeds.
