My son's old gaming rig has been mining for a couple of months now and he has been tweaking the OC.
He has arrived at 37.8MH/s @ 98w. 51degC with the fan at 61% Is this about right for a 2060 Super 8gb?
yes about 2 quid a day i guess. He has arrived at 37.8MH/s @ 98w. 51degC with the fan at 61% Is this about right for a 2060 Super 8gb?

Contributing to the electric bill I hope!
Wonder how many kids around the world are burning their parents electric to make a loss on mining.
at the momment most graphics cards will make a profit.Wonder how many kids around the world are burning their parents electric to make a loss on mining.
With the correct settings you can get to around 130w of power on most cards. 3060/3060ti.
370 I'd guess around 160.
That's like leaving 3 light bulbs on. Maybe adding 5 to 10p power 24hr period for most on a good energy deal. I think i pay around 8p per kw of electric.

Do people over estimate the cost?

3070 is also about 130 W. With the correct settings you can get to around 130w of power on most cards. 3060/3060ti.

And you’ll likely be paying at least double that for your electricity per kWh, and there’s the standing charge on top of that. I factor about 20p per kWh. That still doesn’t hugely change the economics of mining at the moment though.

How much are you being ripped off?
It can vary depending on your standing charge.
Some standing charges are higher and you have a lower per KW charge. I thought ours was lower, but that was last years tarrif hence my initial calculations, which were a bit mis leading
Now we pay around 16p per KWhr and a 7p standing charge daily.
Before it was a 11 or 12p standing charge and a lower per Kwhr i think around 8p.
Either way let's assume my card which is around 150w (seems stable and not going to ruin stability for 20w) and 60Mh/s over 24hs that's 3.6kwhr which costs me directly around 55p at a very rough calculation meaning I'm still going to make around 3.50 per day at least, if I'm lucky I can earn double that (it seems in onr 3hr 30 period yesterday night i made 1.3 euros instead of 80c...!
Granted I don't account for the standing charge because I'm paying that irrespective of whether I'm mining or not
In just over 3 weeks, I've made 102 pounds. So just under 5 pounds a day, off one 3060 Ti.
17p K/w about 200 watts consumption, including power etc, so 25 quid electricity every month I estimate. Should be on target for 130 a month, less electricity, is 105 month profit. 3.5 a day. Not a lot really but hoping gpu prices stay high will be 'free' money.

Nice one, my 3080 has now paid for itself and my 3070 in the garage continues to chug along... even if the bottom were to fall out of the market, supply is so, so bad for these cards right now that I think GPU prices will stay high for a good couple of years. 17p K/w about 200 watts consumption, including power etc, so 25 quid electricity every month I estimate.

I'm still looking for more cards for the garage rig but I'm not paying scalper prices, so just find myself waiting for more FE's to be released.
Is my power consumption normal? According to NH my GPU is pulling about 350W, with about 106 MH/s. I’ve used MSI afterburner to tweak settings as recommended on NH website.
My smart plug is reporting around 434W draw so that would include mobo and other ancillaries. Still surprised that my gaming PC draws this much energy but that’s a topic for another day.
Edit: sorry forgot to add my card is a MSI RTX 3090

You didn’t say what card
At that hashrate and power consumption I assume it can only be a 3090. If that's right then the power figures seem a little high, but not beyond belief.The consumption is about double what other people report.
I also think 350W is actually max of what my card can handle. In other words I don’t think the MSI settings is applied. I’ve set the power limit to 80%.
With the 3090 you just need to be mindful of your VRAM temperatures.
Many people add a 1 or 2mm thermal pad which reduces the temps from 100+ to low 90s which is much better.
It may also be worth running with the side of the case open , while I know they are designed for 100+ I wouldn't want to mine on one at these temperatures.

Cheers, I will open the side for more airflow. According to GPUZ the VRAM is around 110C at full pelt.Many people add a 1 or 2mm thermal pad which reduces the temps from 100+ to low 90s which is much better.

In regards to power consumption it doesn't seem to restrict the draw, however looking at the efficiency (about 350kH/joule) it looks ok.
Sticking thermal pads would involve opening the GPU up, which if I am not mistaken, invalidates the warranty. Don't really want to risk this on a 3 month old GPU.

Depends on the card manufacturer, some are OK with it, others not. Best to ask.I can't remember if accessing the VRAM chips requires re-application of thermal paste or if you can do it from the back plate.

Are you using a lower voltage limit or is that temp with that dialled in?In regards to power consumption it doesn't seem to restrict the draw, however looking at the efficiency (about 350kH/joule) it looks ok.

Some useful discord channels too - I found them very helpful.
