    Your Skylake laptop from 2015 boots faster than my Zen 4 desktop from 2022 (with a PCIe Gen 4 NVME SSD!)

    This thing takes 25 seconds just to POST. The fucked up thing is that it used to be even worse, but has slowly been improving with BIOS updates. The good news is that once it's up and running, this machine is ready to fuck. Programs open the second I click the icon and loading screens don't exist in games anymore. But it's still disappointing that AMD can't figure out how to make their shit boot faster.

    It’s an issue with ddr5 memory checks. You can disable the checks but you might get instability.

    tell me more about this. where is this issue documented and how can i read more?

    [–] [email protected] 4 points 5 months ago* (last edited 5 months ago)

    It's called memory training. Disabling it will hurt either stability, performance, or both. I really wouldn't bother. Just use sleep mode if time is of the essence. Don't unplug your machine from the wall; if it remains powered a lot of systems will skip the training.

    You can enable "Memory Context Restore" in the BIOS. There are also "DDR5 training options" you can mess with if you know what you're doing.

    But like I said to the other person, the best way to speed up POST times is to simply keep your BIOS up to date. That alone has sped up my PC way more than any setting you can change.

    thanks for the tip, i have it updated but it still takes a good 20 seconds to post still.

    annoying when your ssd can theoretically read everything it needs to boot in less than a second

    ill try reading up on how this training works.

    [–] Psythik 1 points 5 months ago* (last edited 5 months ago)

    Yeah I already did that but it's actually faster now to leave the memory training bypass shit off. (And like you said, bypassing memory training can lead to instability.) But when this motherboard first launched it actually did help speed up POST times.

    I'm just glad that AMD is committed to working with motherboard manufacturers to keep the BIOS updates coming. This is my first AMD machine; I'm used to getting just one update over the course of my machine's lifespan—if even that—with the various Intel rigs I've built over the years.

    Edit I misread that, I thought you had a Zenbook not the AMD desktop lol 🙈

    That's actually insane because mine is also an Asus Zenbook. It's the UX501 that I got at a liquidation sale, and I refuse to give this thing up because they really don't make them like this anymore.

    I'll probably eventually move onto a Framework once this thing gives up the ghost, but I'm hoping for at least a few more years of use.
