i was thinking the same at you until i actually measured it with my wattmeter, and the wattage were almost the same, so the tool is definitely working

wattmeter it's not needed anymore, there are very precise tool nowadays, like the nvidia one and the corsair link, tollerance is only +-5% max

if you don't believe me just try it your self, use the nvidia tool, and then do the ultimate proof with the wattmeter

Ok will check it out

Can you still post your settings please? Wink

Btw are your cards also starting with 1900 mem instead of 2000Mhz? This really annoys me.

yeah 3800, i'm not mining etheruem, i don't like that i need to OC the mem so much, it may be a bad thing in the long term

last time i was able to do 100w 29MH, i posted it here few weeks ago

ok i tested it now

this is with the gpu attached to the monitor(not with the mining rig but the gaming one), 1440p so there is some instability, because i'm using the pc also for browsing and video, that's why you see 24MH as a lowest, but the average is definitely 29MH+

How does clocking the memory up damage it? Unless it pushes more voltage into the memory it shouldn't do anything. At least in regard to the GPU clock upping the clock rate has no change in voltage and assuming the memory is also just an offset, there is no voltage rise.

I got mine at +750 mhz and 50 power limit running smooth right now 30-31 mh/s

Hmm I like to know my wall values, cause the cost is based on that.
Not really concerned with internal wattage.

Thanks for all the info

Now I must look into my psu efficiency.

Indeed the PSU efficiency is pretty important you got some good PSU's on the market that are also very efficiently when you use them..

Right about that because if you do not have a good efficiency it will cost you a lot of watt, I think you always need a good one!
For normal users its already important but for miners even more!

I also have a corsair PSU with Corsair Link enabled, and it reports about 70W more consumption than my wattmeter. So, Corsair link ~ 900, wattmeter 820.

Which one should i trust? Huh

What input voltage your wattmeter and your Corsair Link is reading?

I have the same question. Does the Corsair link give similar reading to the one from the wattmeter?

Wall socket is an extension cord itself. You pay what your providers electricity meter shows.

Wattage keeps the same but you get a voltage drop depending on your wire size, distance, voltage and some other things. When voltage drops amperage goes higher, when amperage goes high enough circuit breaker cuts off, hopefully before something melts. PSU efficiency is better with higher voltage but I doubt if that has any meaning in this user case. I will try that tomorrow.

So for heavy use you want to have short and heavy cables, high voltage and good connectors.

900w in...

the wattmeter is at the wall?

At the extension cord...Why does it matter?

because it can lose some wattage, do it at the wall

900 w is the IN or the OUT? maybe that is the efficiency

if you don't believe me just try it yourself, use the nvidia tool, and then do the ultimate proof with the wattmeter

In nvidia-smi the values are the same as you reported, but its just a computed "current_tdp * 180W".
I dont state that those values are incorrect - they probably are on the card level.
Nothing internal however can know your PSU efficiency, which directly translates to power at the wall.

Looks like my efficiency is kinda low for lbry "135 / 160 = 0.84". Strange cause this is a gold corsair PSU at 50% load which should give around 90%.
For ETH the efficiency is pretty similar "99 / 115 = 0.86".

ah yeah when you measure with a wattmeter you need to account the efficiency, for that i use corsair link(you need a corsair psu with the "I"), which display the IN and the OUT, the OUT is the real usage of your system minus the efficiency for the psu

like this

so here i'm losing 70w at the wall, due to the efficiency

Does anyone have rigs built with nVidia cards ? Which model/manufacturer is the best one?

Thanks

I tend to prefer EVGA 1070s. The SC one with backplate and single 8 pin power plug. YMMV

I second that! EVGA is all I use.
