Topic: How will this change the world of mining?? GTX 1080 / 1070 - page 20. (Read 134124 times)

i'm also waiting, should be launched with the anniversary update of win 10, wait until later today

not yet, i am also hoping August Geforce driver improves Etheruem mining hash on the 1070 

Hi .

Any news about this driver ? 

seeing mixed reviews on this site about the asus strix fans.

personally - i love them (so far). they are quiet, dont run overly fast (~60% while doing 240MH LBC), and look cool as ****. based on the sweet RGB/looks alone, I assume they will retain a good resale value compared to "bland" models like the turbo/FE

Im planning to buy 2 more today though and looks like the store has better stock this time (almost every model 1070 is stocked) - what is the best for low noise, good resale, and fanlife?

$579: ASUS turbo, MSI aero  (both blowers)
$599: ASUS strix, MSI armor
$615-630: other various models of EVGA/strix(oc)/MSI
$645: MSI Gaming

if the MSI gaming wasnt 10% more expensive than the strix id probbaly go that route, but figure the faster ROI will ensure i make my money before the card fans can die anyways.

the blower-style units probably have the best fanlife (ASUS says 4x longer, doesnt make it clear if thats 4x longer than tier own products or some magical junky benchmark), but i have an open-air case so te blower effect doesnt really achieve much besides extra noise and a lack of pretty RGB light

PS: im running a rig with 1x GTX-170 and 3x R9-270x cards just fine. took a bit of tinkering to configure:
1) installed the AMD r9-270 cards, driviers, and used the radeon global overdrive. also did bios mods to 1.1V
2) shutdown
3) unplug all the AMD cards from system, install GTX1070 + drivers + gputweak
4) shutdown
5) plug everything in (GTX as primary on a 16x riser, the rest via USB risers) - boot up. everything works but i cant adjust the AMD overdrive settings (which appear to implement anyways) without plugging in a monitor.



It boots and mines fine headless, but the radeon software refuses to open up (and afterburner is unable to pull sensor data) unless i plug in a monitor. Guess ill need a dummy plug (I only have 10 ohm or 2.2kohm resistors though, not the reccomended 75 ohm - so that may have to wait a few days)

update: added another GTX 1070 today (so glowey!!) without a problem. still room for 1 more but the 16x-16x ribbon riser is obstructing the use of a usb riser - guess id have to make all 6 run on the usb risers to make it fit, but thats a task for another day (and another $700cad gpu)

Next time I move over to Neo I'll screen cap for you, but there are many threads where people are doing the same...

Right now feather is so low that I'm on eth.

1.2MH on neoscrypt is impressive, even for linux do you have some proof of that hashrate?

I do know it does 26 -27 Mhs on eth using 131w @ 64C stock running Ubuntu 16.04  

It also gets 1.2 Mhs average on Neoscrypt using 181w @ 68C also on 16.04 ccminer  sp fork

It also does pretty well on lyra too

I'm happy with the 1070s and feel confident about roi considering they work pretty well on eth for now and can also switch around to other algos when eth diff gets too high.

What else is cool about pascal is that I all ready have a few gamers that will buy them if I pull them offline.

My main computer only has room for 2 GPU's and the PSU would only handle 2x GPU's at a 170 TDP each before topping off the ideal efficiency range anyway. The 2 power connectors would not be an issue unless I planned on migrating the GPU's into a dedicated rig for mining. I am just trying to investigate if the extra power phases actually would result in a greater overclock or undervolt, or if it is just candy on paper.

Only ones cheaper on Amazon with a single 8-pin is the EVGA SC ACX or this ASUS that doesn't appear to have a good cooler. Anything else is too large and would interfere with the bottom HDD cage if I got a 2nd card, or is more expensive.

I will come to a decision on the EVGA SC ACX or the EVGA FTW soon

I think Afterburner just displays that category as a fixed graph but accurate readouts on the side. It's never fluctuated at any point, with either card. On another thread a guy suggested there's extra hash power there, and I probably just have to tune my card and miner to get that extra speed irrespective of the flatline problem, at which point it may stop happening. He runs a farm of GTX 1070's and 1080's but is tight with his scripts and tricks (understandably). Having said that, he'd never seen this exact situation. Afterburner may be inaccurately reporting what's occurring. I'll dig deeper into nvidia-smi logs and see if I can get info at the exact time of the next "flatline." I'm also going to start a new round of tuning the card, miner, p2pool, etc. I've never done much miner and p2pool tuning, so I gotta dig into that. I can't seem to find much detail on tuning ccminer. I think even my vertcoin-qt server can be tuned. I'm using someone's web settings of "block_nTime=1317972665 and block_nNonce=2084524493" in the vertcoin.conf file. No idea what they do yet. Time to research...

Hmm I thought that yellow core clock line shows that hashrate has been stable for long period of time.
Now I realize that it keeps jumping, but is not reflected on the clock graph? (1500 mark is at the same place on both screens).

I'm pretty sure the 1696 was just chance of when I hit printscreen. I had seen the clock higher moments before (I think, I'll verify next time it happens). Besides, the card's baseclock is 1695, so it frequently jumps up with 125OC and then briefly down to that level. Higher power just adds tons of heat (temp quickly runs up to toward 80 and fan revs up too for very minor gain in hash). 100% power never comes close to the efficiency and heat readings I'm getting at 81% power, +125OC, auto fan, and the weird "flatline" thing. It's so strange. Two different cards, two different manufacturers did this. The MSI FE would get up to 85 degrees or higher when it happened, so I sent it back. With the gigabyte it's great, the card runs so cool, but I can't figure out how to make it stay in "flatline" mode, or if it's even possible. Was hoping to trouble shoot by finding out if anyone else had experienced this. Maybe someone has.

Your "flatline" happens for core clock 1696, notice that when its bumpy the clock is at 1835.
So my idea is that on a constant(unlimited)1835 you would have an even greater hashrate, but driver is hitting OC / OV limit and keeps throttling the card to keep it in limits.

It might be a driver issue that it keeps switching between those two "modes", or you are just at a boundary of two boost modes.
Anyway, to force the flatline I would force the constant 1696 clock, or raise the power limit to not throttle the card at 1835.

Has anyone else noticed an issue with the power flatlining and the hash rate getting a boost? I've had two separate cards, one MSI FE, the other Gigabyte G1 Gaming, and both will run for hours (sometimes days) at a time before the power goes from it's usual noisy band to a flatline. The plus side is the hash rate (on lyra2v2) goes up 2-4%, while the power reports being at the limit (81) or sometimes lower (71, see pic below). The downside is the GPU temp increases 3-4 degrees, which is fine because I run it at a cool 69, so it only hits 72-74, but still, I'd like to know what's happening. I suspect my PSU (EVGA 500W) is not enough for an OC'd 3-fan 1080, but I'm limiting the power to 81%, and there's nothing else running on the machine besides p2pool and a wallet in server mode. Anyhow, it was an amazon warehouse deal, so someone else returned it, possibly for this exact reason. But the thing is, I like this, and I'd like to know how to *force* the card into this mode, because I'd like to permanently get the bump in hash rate. It'll stay in this "flatline" mode for hours, sometimes 24+, but eventually it goes back to the normal noisy band, then returns again later (usually around 12-16 hours).

Win 10, i7-4770 3.4 Ghz, 8GB DDR3, EVGA 500W, Gigabyte GTX 1080 G1 Gaming (not OC model, but base clock 1695), in a Dell XPS 8700 (yes, it's a factory dell and MB, I know, I know).

Normal (Core Clock says 1696 but that was just chance when I hit printscreen; it's usually higher):


Flatline "Boost":

For the 1070, the power consumption is low. There is no need for the 2X8 pin, which can support up to 375W.

2x8 pin are bad, don't buy them, there is no reason anymore with pascal to have 2x8pin card they just force you to buy an expensive psu with additional cable that won't be available with the psu itself

I got one last thing now

I looked through the entire thread. For the msot part a GTX 1070 is a GTX 1070 but I have not seen any post about getting an EVGA card when using finder, let alone this FTW edition. 10+2 power phase and 2x8pins

https://www.amazon.com/EVGA-GeForce-Adjustable-Graphics-08G-P4-6276-KR/dp/B01I60OGUK/ref=cm_cr_arp_d_product_top?ie=UTF8

For those making dedicated mining rigs, the 2x 8 pins is a problem. Otherwise would there be a reason to avoid this for someone who is just using it in their normal desktop? Only possible problem I could see is that the card might be absolutely awful while idle or have some minimal TDP as I saw a post critique one other card over such an issue. I emailed EVGA about the minimal TDP to be sure.

So long as nothing forces the card to be consuming a minimum TDP of some amount, this would appear to be a deal.

edit:
Here is the post about that TDP minimum

Claymore hasnt released his dual miner for nvidia cards yet.

only dag algo, it perform very well on other algo, the dag algo problem will be fixed soon, it's only a matter of driver

I have a question

Does the GTX 1070 only do poorly with Eth in windows, or is it for all coins?

And how does the GTX 1070 perform on dual mining. I am not seeing mention in the last few pages.

I read exit a new bios for gigabyte gtx 1070 g1 gaming , but i dont know the advantage .
