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

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

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.

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

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.

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

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.

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.

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!)

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.

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.

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).

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

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

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

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

I dont have win10... for me its an unstable and unfinished os... i stay on 7 for a few years

Just tried Ethereum, it's still broken in OCL and in Cuda mode. I get a queuebuffer error in OCL and in Cuda I get a 'unspecified launch failure' after it finishes building the dag.

Perhaps a chunk style loading might be needed (even if devices have enough memory) on W7/8. Since in W10, the newer WDDM version increases the chunk size.

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.

Wow , with my nvidia gtx 980 OC 1500gpu i have now 780 kh/s on windows 10 x64 on neoscrypt with FTC .
