Hi
DRAM is only as fast as the slowest memory cell/s and, from my reading, the remaining cells are capable of MUCH faster speeds than what that slow/bad memory cell/s is capable of.
It's possible to disable the bad/slow memory address/s using this driver to add entry/s to badmemorylist on the {badmemory} section of the windows BCD: using this driver:

IMHO overclockers and tweakers will gladly give up a small amount of memory capacity for far greater memory speed. I certainly would!
So I suggest you/AMD look at incorporating this functionality into your upcoming memory OCing app.
Plz do pass this along to the relevant developers, whoever they may be..?
PS:
You might also look at extending StoreMI's functionality and competing with Intel's Optane caching by looking at prsyahmi's GpuRamDrive as a starting point. (same author)

NB that the above version does NOT work on AMD cards.
Here's a version that does:

eBoostr (File Aware, specifiable Caching) will give you an idea of how well it might work.
It's still available here and 'free' for 2 hours:
