I use linux pop os and have this cpu. Just upgraded my system from 32GB of ram to 64GB. Bought new kit thou, and put my old 32GB up for sale… And than i thought why shouldnt i put that 32GB kit also since i have 4 ram slots to see how 96GB of ram looks like. XD And when i did that, while my pc was booting, i remembered my cpu only supports 64GB max. So i thought bumer it will not recognise more than that and i will not be able to use it. But shortly i was shocked to see that all 96GB was there and ready for use. So it isnt true that ryzen 7 2700x supports only 64GB i mean its not small amount but it isnt its limit obviusly… Since my motherboard MSI B450 tomahavk max supports up to 128GB i think this cpu can also handle it.

But the thing is this motherboard was rated for 64GB max when i bought it. But than new cpus came out and amd sad they will not be supported on this chipset. But than people started protesting because AMD was advertising this chipset like platform for longevity and were telling that it will be long supported. So people were angry when they sad new cpus wont be available on this platform. So AMD changed their descision and made new bios for b450 chipset motherboards so that new cpus will be supported. And also since new cpus support 128GB of ram this motherboard also got support for that but only with new bios if i understood that corectly…

Also the thing with new bios is that if you update to it you will lose support for old cpus, and wont be able to downgrade bios.

But with old bios your motherboard doesnt have support for new cpus.

But since i have old cpu, ryzen 7 2700x i didnt update my bios so with old cpu and old bios how the heck do i have support for more than 64GB of ram.

Its like you just put more ram than its rated on the website and it just works… XD Like they didnt expect someone to actualy buy more than max ram rated so noone will notice that we are lying about computers limits… XD

Wery strange to me, if someone understand what is going on here, be free to explain it to us. :)

    I’ve got a ryzen 1700 for my homelab. At this moment it is running with 94 gb of ram and will get its additional 32 soonish. It’s working quite well.

    Don’t forget to run Memtest ti make sure it actually works rather than just “works”

    Creeping corruption is a bad time

    It isn’t supported, doesn’t mean it won’t work ;)

    They don’t claim support above 64GB because it hasn’t been tested and if it doesn’t work, you won’t get any warranty/guarantee/whatever for it. Meanwhile if your CPU doesn’t recognize 64GB or below, you may be entitled to a replacement or refund, for example.

    In a similar manner, I believe that on certain motherboards you may be able to use ECC (error correcting) RAM with Ryzen 3000/5000 series CPUs, even if it isn’t officially supported by AMD.

      So does this mean that my older intel i7 7700k could meaby also support 128GB of ram if someone tryes it… 🤔

        It could. It might not. But it’s intel so the probability they’ve actually locked it down is higher than with AMD. But hardware is often more capable than what the specs say. That’s why overclocking is a thing or, in the past, you could unlock an extra core on some processors. It’s just never a guarantee and can vary from part to part, even if it’s the same model.
