i tried to type it in cmd, but nothing happened, where i should type it ?
thx vm 4 reply

thx very much

GTX 970 4gb SSC EVGA @18MH @148-150Watt

seems too much, try to reduce power limit to 50-55%

sorry for asking alot but can you tell me how i can do it ? and does it reduce my hashrate, because in a couple weeks i will buy another gtx 970 and make it SLI and i only have 620watt coolermaster psu, so less watt's will be helpfull

run msi afterburner, and activate powerlimit, via the correct skin, then reduce it to 55%

It's not the "2 cards in one rig" that's an issue - it's the "2 cards pulling WAY TOO CLOSE FOR COMFORT to the power capasity of your power supply" I'm talking about.
However, I went back and re-read, and noticed 970 - for some reason I was thinking 980.
2 GTX 970 should be OK on your existing power supply as long as you don't massively overclock or overvolt/overclock them.

I prefer a simple "nvidia-smi -l 10" for my report window - the "10" part sets the auto-loop to 10 seconds, adjust to your preference. That report would be perfect IMO if it reported active clock rates, but it's close enough as is. It's also a much smaller report than PrecisionX, and shows all 3 cards at one time (don't get me started on the massive waste of space Sapphire's Trixx utility chews up for about the SAME functionality as EVGA's PrecisionX).

thx bro, yea i wont overclock them at all, i will leave it as the original clock rate that it comes with

r u sure ? i see alot of ppl mining with more than 1 gpu on 1 rig ? why would alot of ppl do that if its bad ? and my system will be using ~500watts, not really good but decent to make 120$ first month then i upgrade my psu

There is no need for SLI in mining. All the cards work independently. It is the same for AMD cards.

i thought i have to sli them nvm thx

SLI = bad for mining, offers ZERO benefit and sometimes causes issues that reduce your hashrate per card.
For a machine that's primarily for gaming, SLI is usefull.

You probably want a better power supply, given your stated plans - that second card is going to be pushing your existing supply VERY hard if you game with the machine or if you ever start mining something on it that can use an NVidia card efficiently.

misinformation you say?

before you say that smi it's not accurate, i have tested with wattmeter and it report the same

how i can use the smi reporter to check the watt usage bcuz i want to sli mg nvidia gpu and want to make sure if my psu can handle it
