The ASUS Prime B450M-K motherboard is in the F tier. You're looking for shared memory details, but only resolution info is available on the official site. From experience with similar boards paired with 3400G RAM, shared memory typically ranges around 2GB. It can support higher amounts depending on the configuration, so it might work well if you need more than 16GB. This should help you decide if it's a solid investment given your current setup.

motherboard has nothing to do with shared memory. there is no memory on motherboards, the 3400g will reserve a part of your ram as it's video memory, depending on the application and the available ram.

it's clear this board isn't great, but for the cost it would be worth it for a full setup over six to twelve months. regarding motherboards, do they really not involve shared memory? like, a gigabyte-b450-aorus-pro-motherboard can reach up to 16 gigabytes if you add 32 gigabits of RAM inside.

There is bro ,Maximum limit for shared memory for graphics depends on the mother board. Like Asrock b450 pro4 limits shared memory to 16gb MSI b450 M2 max limits it to 2gb I think asus b450m k limits it to 4gb I think

Thanks to @Shreyasb, I’m fine with it being as low as 2Gig. I just changed from a 1gig GeForce GTX 650 to a Galaxy GeForce GT620 on my current setup—down from 384 CU cores to 96—but it’s now running smoothly again, lol.
