Why no one tried to answer the questions in this post?
I'm in a similar position. My card is 8GB RX 580 OEM made by Dell (a rebranded RX 480), a mixture of Samsung and Hynix memory. GPU-Z shows only Hynix.
My answer is you don't change the memory type. Open the BIOS rom with Polaris Editor, you can see 2 sets of memory straps, distinguished by a number 1 or 2 in front of the frequency labels, either 1:frequency or 2:frequency
Each corresponds to one type of memory, as shown under VRAM list. If Samsung is the 1st entry under VRAM list, then all 1:frequency straps are for Samsung memory only, and the 2:frequency straps are for Hynix only.
You need to use separate timing straps for each memory type, because they behave differently. If you use Hynix timing for the Samsung straps, it won't give best result.
Other than that, I do have undervolting problems. Any attempts to undervolt by AMD Radeon Setting, OverdriveNtool or other tools don't work, voltage never went below 0.988V. Don't know why.
