    Bloody good price. I spent over double this for 64gb 3200 cl16 ddr4 a couple of years ago. Crazy how much prices have come down

    Reminder for those new to DDR5, samsung b die is not the best die like it was for ddr4 (The hynix dies are the best for ddr5)

      More specificially, A-die followed by M-die

    You might be lucky and win the silicon lottery. However, I thought I share the opposite side of the situation.

    I bought the 2x16GB XMP kit and returned that because it wouldn't work properly with my AM5 system. The motherboard I used was happy to read the XMP settings. I don't rule out I have a rubbish AM5 board.

    • Had to upgrade to the latest BIOS to even get the system to boot with that memory kit.
    • Despite the latest AGESA is meant to better support Samsung memory, I could not get 2 DIMMs of that kit to work consistently.
    • I had to start with 1 DIMM, get the system to boot, then put in the second DIMM. While that worked, once I turned off the system, waited an hour or so, turned it back on, wouldn't boot anymore.
    • Memory context restore turned off so memory training performed every single time, didn't resolve the issue. At DDR5-5200, memory training is quite fast.

    Switched to SK Hynix M die kit (would have preferred A die, but my budget is limited and no bargain A die available at the moment). Put that kit in, got it to run DDR5-6000 (the kit I bought is DDR5-6000). The initial memory training took 2 minutes, but can have context restore turned on so it now takes 3 seconds to finish BIOS boot.

    My suggestion: go SK Hynix A die or M die for AM5. They cost a lot more, but far less headache.

    • What's the cheapest 16gbx2 Hynix A die?

    Wow 64 gig, that's a lot! Practical reasons for having so much ram for your average joe?

    • +1

      Chrome tab galore

      • Lol true I do have dozens open at a time, not chrome though, opera or brave. Even when several dozen are open, 16 gig seems to do the job for me at least.

      Virtualization.

  • I opted for a CL28 5600mhz kit (32GB) I believe the CAS latency is very important and IMO is often overlooked in these DDR5 deals. My ram is running at 5800mhz, I haven't tried pushing it to 6000mhz or above.

    • Depends on the CPU.
      It's far less important in X3D AMD chips

  • Nice find, would you say its a better deal than the previous one I'm currently tempted to buy?
