Decred sp-mod #9 does 3.3 ghash on the 980ti. 2.7 for the 1080 is low
yes but with what consumption? 1080 can do 3300 with oc too, but consuming only 180w, the 980ti will consume like 250 or more
Sources?
Hypothesizing is fine, but mark it as such. Don't state something as fact unless you have sources for it.
mmmmm 1080 nice
is the above run at stock?
wondering what the power draw is ? if you don't have a watt meter, what is the percentage of TDP that the card is averaging ?
it has double the hashrate of a 970 with the wattage of one for decred, which is really good, but it cost 3 times more, not worth it for the moment, also decred is bad to mine versus eth
Decred is so bad right now that it makes less profit than mining lyra2v2 with a 750Ti or quark with a GTX970, that bad
Yup, still getting hammered by the Claymore AMD miner... If only Nvidia had something like that.
Real test is going to be what a 1080 gets in Eth with the fucked up memory issues since the 1080 uses a different type of memory and bus.
this guy is an insider, he tested both 1080 and 1070, they perform better than any gpu right now on any algo minus ethereum
and this without counting optimization and proper drivers
Not sure I believe 'all at 180w' unless they have a watt meter. A lot of people thought 970s wouldn't go over TDP or close to it. Doesn't show clock speeds or TDP either.
Currently I hear the 1080 throttles in games too at stock speeds, doesn't mention whether or not the fan profile was increased or if that happens under prolonged mining.
970 it's actually under tdp, those that have it above, don't know what power limit is and how to use it on msi afterburner, and or they are buying 8+6 pin gpu with again PL at 100%, which push the wattage to unnecessary level
i'm now at around 125w for 19.5MH with a 970
There isn't a correlation between power connectors and wattage besides on 750tis which generally don't come with a external power connector. I have some 6x2 EVGAs that use less wattage then Asus cards with a 6+2 connector. It's all based on how they're binned and that has nothing to do with power connectors.
You can't trust reported numbers on the PC itself, you have to use a watt meter. They've been proven wrong time and time again.
i have used both, and wattmeter display the same thing, unless now you want to say that even my wattmeter is broken
actually the wattmeter will report only the full consumption, including the whole system which will drain an additional 50-70w, so it's not that good to measure with the wattmeter the correct wattage of your gpu
result are the same 135w at 20.5 mega and 125w at 19.5 mega for each 970, the smi thing got boosted, it's pretty accurate now
If you use the same system, system load doesn't matter between different cards you test.
We're talking about card TDP, it's not always accurate. More then one person has confirmed that in this thread, myself included.

Hi
I agree with bensam1231 on this one, you can only trust an AC wattmeter, sometimes GPU power reading is close, but a LOT of times is WAY OFF reality
an AC power meter measures the real thing, that is, what you pay every month!, and that's what matters the most. how much $$$ costs you to have your farm in operation.
the very first thing i do when i assemble a miner, i put everything except the GPUs, and power the rig, wait until the os loads, and with the system running and fully OS loaded, I measure how much does it use, in my case is 16W right now. (that includes the LCD and power bar), then I put all cards in.
With this readings I know how much every card uses (total power - 18W (mobo), result /3 and i know exactly how much each card is using)
this is not accurate either, because when you run six gpu on a motherboard it consume more in comparison with a empty motherboard, so from 18w like in your case, it may increase to 30-50
the same for cpu, anyway like i said, i did measure it with the wattmeter, and it report the same plus those 50-70w for other component, i'm running additional fan on my system, so it's there, smi is telling the true
That doesn't make sense. Only thing that would cause more load besides the CPU running at full frequency is the cards. You could turn off power saving features like cool'n'quiet or speedstep if you want to be really anal. Adding more cards shouldn't increase system load outside of the cards themselves. Something needs to draw the power.
actually it make sense, when you use more gpu, the motherboard need additional current, so there is a bit of more consumption for that, and the cpu will work a bit harder, we are not talking about crazy vlaue, but those additional 10-20w are there
there was even an article in cryptoblog saying that
for smi, you need to check the last version, it's pretty accurate, you can do it your test, even another user was surprised when he tried again, recently, and anyway like i've said i've tested with the wattmeter to be sure, and they are around the same
also gpu efficiency matter here, i have the 1500i, which has one of the best efficiency out there, so overall the consumption is lower by few watt because of this
there are many variable that simply can not be ignored, it's not so straightforward like many think
What are your exact settings for 970 (including afterburner and cuda intensity for miner)?
55% tdp, but the first gpu crash it seems, it crashed today, intensity is at default, everyhting at default, minuc oc at +150/+150 on afterburner
)
but if that PSU is good, and you keep TDP low, it should be enough, my rig uses 300W at the wall mining quark with 6x 750Ti so, 650W PSU, if can really take 650W, would be enough. for example a GX650 Coolermaster is a nice little beast, it will leaf is ass of with only 300W of power consumption hehe.
