A lot of confusion my friend, you are mixing a lot of things.
Lolminer and it’s “3060 booster” requires any driver from the range of 455.45.01 up to 460.39. Of course, naturally, we all use the latest working driver which is 460.39. Although, personally, I have used 455.45.01 on one of my rigs with a freshly installed HiveOS image (which comes with this driver version installed).
Even with 460.39, when mining ERGO, there are certain OC settings that makes your hashrate drop to 70-80 Mh/s. At the same time the wattage drops to the 80-90W territory. Does that mean that the limiter kicked in? No. It’s just that the card switches “performance mode” (similar to what AMD calls “Power state”). When you tweak the core again it goes back to full hashrate (120+). Similarly, if you mine ETH -even with 460.39- the limiter kicks in and afterwards, no matter what you do, ALL algos will be limited.
The above is proof that the limiter is only algo-specific and it will only kick in when mining ETH.
As for why the two algos are different. The fact that you can switch to ERGO with the same OC settings as ETH means absolutely nothing. As a matter of fact, in order to achieve the best ERGO hashrate and/or efficiency, you need to change the settings a lot. ERGO is a lot more core dependent than ETH, so you need to bump your Core Clock up instead of driving it all the way down as you do in ETH. Also, the fact that the algo accesses memory in 32 byte chunks, allows for a lot higher memory clocks than ETH. And that alone (the memory access allocation) is enough of a difference between the two algos so as not to be “confused” by nVidia’s limiter.
Very interesting discussion whatsoever to say the least!
