Preface:
I recently made a rookie mistake that I sort-of had already been thinking about before I received my card. With regards to core clocks by this point I'm certain it's just the luck of the draw as I have seen a huge range in stable frequencies. This is besides the point in generally up to you and how much power you want to shove through your GPU.
Actually important:
I had been running my GPU at +100MHz on the core and +1000MHz on the G6X with no issues whatsoever. I completed my suite of benchmarks and when I had somewhat respectable numbers I called it a day and began putting this R18500 to work as I haven't been gaming that much in the last few months. For the first time I had memory artefacting and a GPU scheduler BSOD. I learnt that the G6X is actually error correcting, and unstable memory OCs may not appear quickly at all if you have fairly good modules. I watched a video of Jay OCing his FE 3080 in which he actually mentioned this topic and demonstrated the FPS loss in Unigine Heaven. Lowering the OC by 500MHz for an effective 20Gbps rendered a negligible drop in Port Royal even though my GPU was holding 100MHz lower of an average boost clock (I wasn't benchmarking with my giant fan blowing at it). I'm not totally sure but I remember hearing of Micron modules exhibiting failures with 20-series cards and if you have a GPU currently holding anything above 700MHz on the G6X, I seriously recommend revisiting your OC.
