Jarred, instead of dropping GPU clocks, keep them flat at+0. The GPU clocks will handle themselves in response to lowering power limit. It's easier, and will net you a few extra MH/s for the same total power. Eth might not hit the GPU hard, but I'm guessing the mem controllers take a hit when GPU clocks drop too far.
I did test at various clocks, and got the best efficiency with the settings indicated. However, I've noticed that other cards using the same GPUs sometimes prefer a slightly different approach to the GPU clocks and power limits.
Your Vega 64 results are TERRIBLE. I get 43.23 MH/s @ 131w running latest Radeon driver 28..8.1. Running ASUS ROG version of the Vega 64, I leave fan settings on auto. Adjust to taste. Using TeamRedMiner with NiceHash 3.0.6.5.
Keep in mind what really matters is your hash rate on the pool.

Is that directed at phxrider's claimed 131W with Vega 64, or at my testing results? As noted in the article, the Pascal, Vega, and Polaris cards are all relatively old now and some were a lot more finicky about what settings they'd run. The power results are for the entire card, however, and on Vega and Polaris the reported power in software utilities is only for the GPU — no RAM, board, VRMs, etc. Some Vega cards would undoubtedly do better than the cards I have for testing, but with the settings I was able to get running stable (including undervolting), these were the results.

What you want to do is make sure your video cable is not connected to your mining GPU if possible & use the onboard video port where supported. This way you get maximum power from your mining card and its a lot more stable.

Hi Jarred,
I must admit I responded without reading about the part you mention about AMD only recording power on usage on the GPU. I don't have a power meter, but I can say that running those 2 cards in my old gaming PC with everything set to low power mode, I've not noticed any difference in my electricity bill. There will be a cost for sure, but it is negligible.

I personally don't like cyber mining, but many seem to feel that in the world of cyber mining, "You will never find a more wretched hive of scum and villainy." However (to extend the reference) Obi Wan then went on to say: "We must be cautious". He did NOT say "We must run away and hide our heads in the Tatooine sand".

Hardware shortages are a nightmare for everyone, including business. Auto mfg can't get chips. Even big players like HP can't get chips. Trying to get replacement parts is near impossible under lease...why? Because capacity is being used up for next gen CPUs/GPUs, game systems, and Mobile/Tablets. These are all highly profitable items on a limited node. TSMC is basically a monopoly in this area.
I don't deny the problem, but the long term solution should not be censorship and quotas which ultimately limit progress and innovation. Like I said, I'm not into the whole mining thing, but if the mob (or big government) could effectively limit or end mining then they may come after what you or I like next.

Well... this article went a bit under-appreciated lol
Personally, thanks for the information! I think it is a little silly that people are so bent out of shape about the mining thing. All the gamers in the world could mine and it wouldn't make a difference in the situation right now. Might as well mine a little bit to recoup some costs or fund some hardware purchases. And for most people the option to mine will go away with ETH goes away, so this is sort of the last chance for many out there.
At any rate, I finally got my super over-priced GPU pulled from a poor college student who made a foolish gaming PC purchase. I bought his card, he is keeping the computer, and I get to finally play some 4k games while he gets to afford another semester of school (and probably hide his purchase from his parents lol). Win-win.
Anywho, 3 days in and this is what I have managed with a Dell 3090:
110-115MH/s
300-305W
~365-375 kH/J
$0.06 /kWh
$4-5/day using NiceHash
-450MHz core clock - Should be able to go lower, but seems to affect mine?
+950MHz Memory clock - hitting a thermal limit of 102c so pushing harder doesn't help. 120c is damage territory, 80-95c is ideal operating temps, but 95-110c is not damaging according to memory manufacturers, but may cause errors. So as long as you aren't having errors, you should be OK at those temps. Provided you haven't modded anything, your card will step in to prevent you from burning up your VRam.
70-75% fan speed on auto - Because of my VRam thermal limit, the fan speed had been up at 100% previously. Ram on the back side of the 3090 are much hotter than those under the main cooler, so I moved some fans around to cool the back of the card. After that, my VRam speeds are comfortably in the 98-100*c range preventing the fans from becoming jet engines, while allowing the higher hash rate.
We will see if I am brave enough, but my suspicion is that my VRam is my bottleneck here. If I swap out the thermal pads (and possibly the whole back plate with something that has some fins... or mod the backplate to have some fins... then I should be able to get a bit more out, and some higher efficiency. But I am pretty happy with it.
As prices are now my card should pay for ~75% of what I paid for it by the end of the year, so $500 for a 3090? I would say that is not half bad. If prices spike up again later in the year, then I'll be able to afford some network equipment I have been wanting. And if BTC goes to $0, then I will be drinking my tears lol. But either way I will be able to play some games for the first time in ~5 years! Pretty stoked for that!
But for normal gamers who have a modern GPU from the last 3 generations... yeah, mine a little bit! Don't be dumb and OC to the moon, or damage your stuff... but if mining profits are baked into the price of the product, then not mining just means you are over-paying for your card. My 3090 cost $2150, but with mining I expect to make ~$1200-1500 on it this year. So my out-of-pocket cost should be closer to $650-950, which isn't half bad for a top-tier card. And my old card is going into the kid's PC, and should mine a solid $400 before the end of the year, so that brings the costs down even further. I'm not advocating any kind of full-on mining farm... but if you have a game rig that needs a GPU now is probably one of the best times to buy. Otherwise wait until ETH goes away and pick up a used mining card for dirt-cheap.

Kudos, RTX-3070 temperature down 10 degrees Celsius, power reduced from 208 watts to 120 watts and the best of all a 20% speed improvement from 51 MH/s to 61 MH/s. Awesome information, I just started mining again and this makes a lot more sense now!
