Curious if anyone is aware of a listing of these anywhere? Used to be much the thing that certain CPU revision codes in the P4/Barton/X64 days made a big difference (and there were certain steppings to look for when overclocking). As IMC seems to be quiet variable at the moment, I'm after ideas of what revisions to look for that featured good silicon 
If anyone happens to have an R7 1700 that both clocks well without crazy volts AND was always able to run 3200 memory with seemingly less issue than was reported - would you be kind enough to check the stepping/revision code. Not aware of any way to get it other than looking at the stamp on the heatspreader.
