The more I use the 1070 the more I think it's not just a 14 nm maxwell card.
Playing with the intensity revealed that some algos prefer a much lower value than, for example, a 970.
There must be something with memory access or, maybe, immature drivers that make higher intensities slower and more "floating" (on some algos only).

Let us know if u discover something interesting

Same happened to the early 970 cards with 2x 6 pin power. They trottle if you push them to hard (high intensity). TDP was set at 150Watt, but for the G1 gaming the TDP was 250Watt. and 8pin+6pin. No trottle and 20% faster hashing in most of the algos.

It's not a throttling problem in my case. TDP is set very low.

For each brand power limiting react differently, so its a bit hard to use same settings, for instance Gainward phenix 1070 with power limit at 85% droping voltage to 0.92v (GPU-z readings) which might be unstable for clock over 1900mhz, even more power limit of 75% will drop it as low as 0.84v
I did some tests with lybr and 85% and 1900mhz is stable, but other light algo might push clock more and restart the PC
For instance MSI 1070 does not drop voltage at all that low with power limit

In a couple of weeks you can buy these 14nm cards from AMD.

Radeon 470
TDP: 110 watt
Retail Price: $159 (4gb)

Etherum classic hashrate stock clocks (23.5MHASH)

Radeon 460
TDP: 75 watt
Retail Price: $99 (2gb)

Etherum classic hashrate stock clocks (23.5MHASH)

2x 1070: $900 (52MHASH etherum classic)
9x 460:  $891 (211MHASH etherum classic)

then ethereum* goes down a bit and you have useless cards.

rx 460 mining etc/eth at 10 mh not 23.5mh

Yup ... 460 is giving me max 11.99mh for ETH

I wrote it before the cards came out.
The 460 has a 128bit bus. (same as the gtx 750ti, 950 and 960 cards)

I buy another 2 gigabyte gtx 1070 today , i try mine lbry with windows 10 x64 , driver 372.54 , and use ccminer-rel1.8.1-vc2013 .

Set +100mhz on clock , and -100mhz on memory , Power Limit 70% .

Temperature is 69° celsius and hashrate is 250mhs for board .

But i see the comsumption is high , around 180 watt for board .

Any Help ? , i want 100 watt max for board .

[reb0rn21]

Drop power limit a lot more, see with GPU-z real VCCD voltage!

Duno about Gigabyte G1, but gainward to not go over 100w power limit had to be set at 50-55 and clock need to be low as 1500-1600 or even less, atm I am on 125-130w at 85 (0.92v for GPU core) power limit and 18xx Mhz click but as I sad Gainward is dropping voltage as mad with power limit!

[giagge]

What is your settings for 100 watt power comsumption , and 250mhs for board on lbry ? .

you can check the gpuz voltage amounts to the left, in the images.

With all the main algos. If you' ve got a question, I' ll be willing to help you, here (so wqe don't go off topic here):
https://bitcointalk.org/index.php?topic=1589403.msg15972194#msg15972194

What is your settings for 100 watt power comsumption , and 250mhs for board on lbry ? .

second tab with lbry, you' ll find all the details to set a 1070 at 80/90W with 200+MH/s. I' ll show you the behaviour in the second article, but it shouldn't scale more than the ones shown there. Nothing exceptional in the G1 except the cooler.

What is your settings for 100 watt power comsumption , and 250mhs for board on lbry ? .

doubt its possible, considering speeds are generally ~270MH/180W, ~240MH/150W, ~200MH/110W

Now try with:

Algo: LBRY
PowerLimit: 60
core: +150

Hash: 250mhs for board , and 100 watt for board .

But some have error with Illegal Memory ?

illegal memory is a typical error for too much clock with too low voltage ))

some questions:

part number of the vga?
voltage, under load, with msi afterburner and gpuz (latest versions)?
power limit
core frequency
ram frequency
temperature
model of the wattmeter (part number it's ok), to check the efficiency of the reading
power supply Part number
system load in W, AC reading

250MH/100W it's way off my readings, not possible with 6 types of GTX 1070 (3/6 are founders).
200/89W it's possible
I need to check what's doable with 100W

thank you

As I sad it depend on the card bios, each card react to power limit different, some drop voltage more some less, depending on that you will have more or less power usage

power limit of 60% there no way you can OC core, depending on real GPU voltage stable frequncy would be 1400-1700Mhz (boost)

[Amph]

200MH at 89w is not worth it

you will lose more than what you will gain with consumption even with high price in electricity

a rig with 6 x 1070 will lose 360MH which is 600k satoshi each day = 0.18 btc per month = 90 euro

and saving 400w only, 400 watt is only 75 euro saved a month at 0.25 cent electricity...

best compromise is 75%power limit no lower, 135w per card but 260MH for each one
