Partition Camping on newer architectures (Long Scoreboard?)

[sBc-Random]

I’ll get back to you with those details, I’m writing this up from memory I’m afraid.

On an aside, this article was written only in 2015 and still seems to indicate similar issues (unless I’ve failed to understand the problem):

NVIDIA Discloses Full Memory Structure and Limitations of GTX 970 - PC...

To avert this, NVIDIA divided the memory into two pools, a 3.5GB pool which maps to seven of the DRAMs and a 0.5GB pool which maps to the eighth DRAM. The larger, primary pool is given priority and is then accessed in the expected 1-2-3-4-5-6-7-1-2-3-4-5-6-7 pattern, with equal request rates on each crossbar port, so bandwidth is balanced and can be maximized. And since the vast majority of gaming situations occur well under the 3.5GB memory size this determination makes perfect sense. It is those instances where memory above 3.5GB needs to be accessed where things get more interesting.
