Look like the 1070 mem perf was fixed in driver 368.69, i now get 950 kH/s on windows (+30%)

but the 1080 seems worst sigh

GPU #0: Gigabyte GTX 1080, 391.72 kH/s
accepted: 15/15 (diff 0.003), 1324.49 kH/s yes!
GPU #1: GeForce GTX 1070, 949.84 kH/s
accepted: 16/16 (diff 0.004), 1325.44 kH/s yes!

Already installed the driver, haven't checked Ethereum and Neo hash as other 'users' reported it didn't fix it. Shame on me for listening to them I guess.

NeoS gets around 1000~ Mh/s on W8.1 x64. Using DJMs last build.

Definitely still room for tuning. Should be closer to 1200. Watching the GPUs, none of them are 'maxed' out and sit at about 85% utilization and MCU is also at about 80% utilization. This may be a intensity issue, but I kind of doubt it considering what Pallas was saying. Intensity seems about ballpark with a little bit of testing as well.

Well I installed new driver, then at some point it said I was on .38 driver again after a few restarts. Reinstalled .69 and 1070 is hashing at 600~(w10), I guess custom clean install is needed instead of express.

so you fixed it now? they should do the same on win 10 like they do on win7/8

also on mcu utilization being only 80%, fb usage which is the sam eis at 80% on maxwell too, so that can not be improved

No I did a clean install and its still hashing 600~, not using insider though if that matters for neoscrypt?
Other algos are hashing fine though besides eth

i think insider build does not matter anymore, they reverted the wddm to 2.0(check your dxdiag now to see what you have)

It's 2.0, I will try on 8.1 later today

Pretty certain WDDM 2.1 was accidentally introduced into the driver install in the preview build in W10, which is why they removed it.

WDDM is limited to certain versions of Windows. 7/8 do not get 2.0+. Based on what I've read, WDDM 2.1 will be introduced sometime this month, which fixes issues with Dagger... NeoS is having problems for different reasons (tuning/optimizations).

As a FYI, I have and have used a couple 1070s... So far it seems as though this generation of coolers is actually worse then last gens (970 series). Asus's new cooler is about on par with Gigabyte's, it happens to run a bit hotter though (around 80s while mining). Gigabyte's cooler seems to be exactly the same as the one from the 970s, with the same crappy fans. However, it cools decently well.

MSI seems to have the best coolers currently, their red (gaming) and white (armor) coolers are both quite good. The red cooler is slightly better by 2-3c, but otherwise they're about on par. However the TDP limit on the gaming is much higher then the armor. TDP on the gaming is at 126, while armor is at 108.

Formerly the MSI armor(white) for the 970 was terrible and overheated extremely easy and was very low quality.

As I've mentioned formerly, Zotac AMP edition coolers seem to be the runt of the litter, regardless of it having a TDP of 120 and very sturdy construction, they overheat extremely easily and seem to have no real exhaust.

I expect fans to start failing on the Asus and Gigabyte models in about a year, that's the going rate for fan failure from Gigabyte with continued mining on the small half-height fans. MSI fans are much sturdier and seem to be constructed better. I've also never had a MSI fan fail. Asus was that way (except for one) with their previous coolers, however the current fans disappointingly look identical to the Gigabyte ones with different fan pitch and blade design.

I don't have a EVGA card, however, I'll get one in the future to test out the coolers and see how well they work.


Something I have noticed so far with the 1070s, they all seem to run warmer then 970s in the same setting, even though the 1070s consume less power. Also TDP doesn't seem to be such a limiting factor of OCing. Which either means that miners can be improved a lot on the 1070s to more fully utilize them or the chips simply will never use that much power. TDP slider isn't as necessary as it was on the 970, which also means lower TDP values aren't necessarily bad (like a max of 108).

As to why they're running warmer? Board manufacturers may have decided to make cheaper coolers because the chips run cooler and they aren't as necessary. Quite disappointed with Asus though, their 970 cooler was much better.

Gigabyte's cooler seems to be exactly the same as the one from the 970s, with the same crappy fans.

What's wrong with the Windforce fans? They are my favourite by far and I never ever had any major issues with any of them on dozens of cards (780 Ti, 750 Ti, 970).

The only issue I had was some fans on 780 Ti's slowing down because of dust but after cleaning they were perfect again.

Here is 1 fan , I have 20 x 750Ti and 10 x GTX970 G1 gaming, all gigabyte, only had problem with 2 central coolers of the GTX970s, but i figured out how to open it and oil it, and haven't had any issues after that.

practically all the GPU coolers are shit, they ones from MSI are worst than the gigabyte and sapphire based on my experience (not to EVEN mention Xfx...geez!)

They burn out. The coolers are pretty good, but the fans wear out after about a year of mining. They're small and use sleeve bearings. Pretty much all manuf. use sleeve bearings, sadly. It's weird you buy a $450 graphics card and they can't even spend the extra bit of money on a more exotic bearing type that lasts longer.

I think eVGA this time around has a double ball bearing, but I don't have one yet. You can usually tell if it has a ball bearing based on spinning the fan. If it sort of 'wobbles' back and forth into place after you spin it, it's probably a ball bearing.

Sometimes this is labeled on the sticker on the back of the fan as well, but not always (especially not with GPU fans).

In my experience it seems to be there is a correlation between the thickness of the fan (shaft length), diameter, and reliability. Thinner and smaller fans burn out faster then larger ones. The ones on the Asus 970s were pretty good. Gigabyte fans burn out quite fast, I've also had lots of problems with XFX back when I used AMD (they used very similar fans to Gigabyte), and Asus is now using a similar looking fan so I expect it to go after about a year.


Ball bearings you can almost always oil as you pop off the back sticker and there is a reservoir in back there. Sleeve bearings are usually sealed and it's next to impossible to open them, especially with GPU fans. If you need to oil your fans on a regular basis that probably means it's a junk fan to begin with. Cleaning fans helps. It seems as though Gigabyte fan blades gather dust faster then other types as well.

BTW I assume all the developers have seen Wolf0 has open sourced some of the less popular kernels? There might be something in there worth picking over for Nvidia since Wolf doesn't optimize Nvidia side regularly. Specifically I see blake, groestl, and skein.

gigabyte heatsink is the best at least it was so for the 970, it cover everything vram included, other gpu were not that good in terms of heatsink

i choose giga all day, but i don't know if this is still true with  he new gpu

[duboisi]

The Gigabyte 1070 G1 Gaming only has 2 heatpipes and it heat up very fast, unlike the 970 that has 4 pipes. Test it out before you buy too many.

so it's more like the old 970 windforce 3 which has also only 2 and not four

anyway i don't rely on the card's dissipation, i use other 3 additional fans to build the correct airflow wiht a simple tunnel effect, very effective

cards alone will never cut it at current ambient temp of 31°, no matter how many they have or heatsink they have

I have a couple and it seems as though it's on par with the Asus 1070. I noticed Asus changed their orientation of their fins and raised the density. There are about 20% more fins per inch then with the other makers. I think this contributes partially to the crappy cooling as there isn't enough space to blow air through.

The orientation has changed from Left-right to Top-bottom, so the air is pushed out the top and bottoms of the card, instead of left and right sides. MSI still uses left-right orientation with the decently sized fans much like the older Asus 970. Zotac 1070 AMP had left-right orientation with decent size fans as well, but that was completely blundered by lack of proper exhaust on the card.

Heatpipes definitely do matter. Also noticed that Asus did away with their really big heatpipes they had on the 970 and use smaller ones.

As far as the Gigabyte goes, it does have one less heatpipe, but the heapipes are bigger then they were with the 970 series. The overall cooling seems to be about the same. I personally don't mind how fast they heat up, rather what they equalize at while mining.

I'm still surprised there isn't a tech website that rips coolers off GPUs and benchmarks them on a hotplate in certain settings. That is one of the major defining factors between manufacturers.

Look like the 1070 mem perf was fixed in driver 368.69, i now get 950 kH/s on windows (+30%)

So the GeForce GTX 1070 is about equal in hashrate  to the 980ti on neoscrypt ?

much more, if you oc you can potentially get 1200 already, 1MH for the 980ti is done with oc already and sp-mod private, so it's far better

not to mention that the 980ti consume like 250w or more with that hashrate, the 1070 only 150w

You are right new eVGA cards seems to coming with ball bearings which are lightyears away from the shitty sleeve bearing, geez!.
but no backplate?, and I don't see that they cool properly the memory and vrm's which gigabyte does fantastically well.

Still ,the sleeve bearing can be opened and oiled, it just takes practice, i separate the rotor (blades) from the stator to oil them but it is tricky to do, the first time i did that i broke the magnetic assembly from the circuit board   (the cost of learning how to do it) next time I need to oil a fan i will film it and upload to youtube

Memory runs cool and doesn't need to be cooled. VRMs on the other hand do need to be. Based on the 970s, I would believe eVGA might be up to schenanagins. As far as the 1070 EVGA's they look to be cooled properly. You can see a plate over the top of all the important bits in some of the photos online.

Any interest in helping us sp-private miners w/ gtx1080's with neoscrypt?  My 980 is getting 700kh but my 1080's are only getting in the 300's

Might be a Windows 10 problem, I don't have time to load in a fresh Windows 7.

Yes my gtx980 get 700 kh/s with windows 10 x64 on neoscrypt ( FTC ) .

The gtx 1070 on windows 10 x64 last driver go around 1000 kh/s i think .

no it's 1080 problem, it does the same crappy hashrate on win 7 too, on the other hand the 1070 is great, is doing 1MH on win 7, but again poor hahs on win 10

not a code problem like someone else think "cough bensam cough", but simply driver problem on win 10 side, you can tell this by the fact that on win 7 it work and win 10 not...

7/8 also get these speeds, which still isn't up to par, but much better then what we were getting before.

Both the 1070 and 1080 need tuning/optimizations to get them up to where they should be.
