Switched my Vegas over to ERGO a couple days ago and it was hard to find good OCs so wanted to create this as place to collaborate and find the best OCs together.

Use TRM for the miner, v.0.8.3 required READ THE TUNING GUIDE FIRST!!!
Lets Talk Power, ERGO can use less power than mining ETH with very efficient settings (core 1225 / mem 847) and still preform at a good hashrate. However If you have plenty of room to increase wattage on your PSU(s) and breaker(s) you can get very high hash rates, comparable to the 3080 hash rate on ERGO with core 1400-1480 and mem 960.
ERGO mining observations
Increasing core has the biggest impact on hash rate.
Pushing core up to 1400+ seems to require about 900 vdd (give or take 25).
This is alot of power, GPUs 1, 2 & 3 below are on a Server PSU with just those 3 cards and their risers, pulling 730w from the wall!
If you get GPU dead or on boot the card does not increase wattage and start mining its one of two issues VDD is too low or core / mem setting is too high. I follow the TRM guide increasing up to 925 and if it crashes I lower Core.
Hash rate moves around alot, my understanding is every time a block is solved and a new job is sent to the RIG hash rate drops temporarily while the GPUs build some table?? but then returns to the full hashrate.
Hynix has lower hashrate with same settings, no drop in hashrate when lowering mem from 960 to 900.
Vega 64 with 56 bios can run at a slightly lower vdd and require a little higher core for the same hashrate (GPU 5)
Questions? Better OCs?
Please provide a screenshot like the one above so we can all see accepted rate and uptime on new OCs. Also makes it quicker if you have issues or questions since OS version, Miner Version, HiveOS image, OCs & GPU brand/memory can all be seen from this page.
