Selling as current mobo is DDR5 and they're just sitting around not doing anything. Especially given the current crisis, go for it. Now, I WILL say I haven't had the chance to test these and I cannot give you a 100% guarantee that they are fault-free. I just can't give that guarantee as much as I'd like to, I don't have a rig to test them in. So you are absolutely buying them at your own risk. I cannot parenthesise this enough. On the other hand, you wont get 128GB this cheap anywhere else soooo.... oh, also, see image for proof of sequential numbers.
