It depends on Windows and drivers version, in Windows 10 cuda8 is faster for 10xx.

Thanks.  Looks like both the ASUS and MSI are Micron Memory.  =(

No problem, glad you got it working. As far as overclocking, it depends. There really is no good single blanket answer. The exact type of 1070, type of memory, intensity level, what you're actually trying to achieve (power efficiency? maximum coin production?) etc all play a role. Depending on the card, Samsung memory can be clocked at like +800 to +900, Micron memory and it's as low as +300. read over the readme and this thread again about the intensity setting. default is 30, you can go higher and your sia speeds will increase. Long story short, you have to see what works for you.

Rookie mistake.  I only used the Windows 10 anniversary update driver.  I thought that was a Nvidia  thing , didn't realize there is actually a Windows 10 anniversary  updates as I normally used to service packs.  This fix the issue.  What is the best OC  level?? I am doing +575 for memory and +150 for clock to get 29.5MH eth n 300 sia.  I see others reporting that the 1070 can get 29 Eth and up to 900 on Sia.

P.S Thanks so much for the help

I might just be reading it wrong, but I just want to confirm... You updated the nvidia drivers and updated Windows to the anniversary update?

Anyone have any idea why my NVIDIA 1070 is hashing so poorly?   Any suggestion to what else I can try?  I just did a clean Win10 rebuild, all my previous builds are AMD.  First time swinging at NVIDIA with Claymore.  People reported I should be expecting 28-33MH not the 1.5-3.5MH I'm getting now.

Thanks! It works now. Cuda 7,5 in 6.3 is still faster then cuda8 in 6.4. 32.7 vs 32.4 with gtx 1070@100watt

I have 2 PowerColor Red Devil 470s, 2 Sapphire Nitro 470 4GB, and one Nitro 470 8GB, only the Nitro 8GB has Samsung, rest Hynix (this is Micron I think).  I have an EVGA 1060 3GB with Samsung. You can check with GPU-Z.

Waiting on CPU and risers for next rig, I can post my findings for others after that (more Nitros, 2 Asus, and Zotac).

OK this is driving me nuts.  Claymore v 6.2 or 6.4.  I can't hash more than 3.5 MH Eth on any of my new NVIDIA 1070 ( 2 MSI and 2 ASUS).  Just reinstalled Windows 10 64bit and using 372.54 Anniversary update driver

ASUS Card memory - GPUZ shows is Micron.  Let me power off and check the MSI

Nah, you can use 2 PSU on the same system no problem.  You keep 1 power on all the time with the the motherboard shorter plug.  The other will power on the system so no issues.  All my rigs are that way and I have over 15 rigs as well as my friend who have 4.5GH.  You can't power 6 x 290 or 390 without using 2 PSU even with a EVGA 1600 when dual mining, it's pushing too much.  Regarding powering more than 2 GPUs, the advice to use power riser is correct.  That's the best way to do it, else you can fry your MB.  Each card PCIE can draw up to 75 watts or more before the driver update for RX480 so you multiply that by 6 and that's too much power to be asking from the MB.   Do not buy the skinny risers with the floppy drive looking power connectors.  They are very cheap and will burn out very easily especially when overclocking.  Go for the fat MOLEX power risers.  I threw away about 30 of the cheap skinny ones,never had issues with the FAT molex ones.  

All my Motherboards are
H81 BTC pro - Don't need to plug Molex into Motherboard (optional and I don't do it) - Press N to disable future warnings

H97 anniversary - Requires Molex into  MB for more than 3 GPU configs.  H81 is better, these tend to have higher DOA based on my collective mining group's experience with combine hashing power of over 12GH.

MSI Gaming 5 - This is the only board where you have to mess with the BIOS settings.  Change PCIE to Gen 1 for all first 3 on the list.  The other setting below needs to be 8x/4/4 instead of default if you want it to work for all your 1x risers.

is there a list of brands with Samsung memory ?

It shows WDDM 2.0 . 

Prolly your system problem, go and run dxdiag check if display is with WDDM 2.1 support, it should be for win10 for mining ethereum

Also reinstall driver and check do a clean install

For 1070 with samsung memory ~33mhs is duable if 2350mhz clock is stable, the one with micron clock a lot less and they don`t go over ~28mhs

if that EthDcrMiner64.exe -cclock 1260,1260,1260,1260,1260 -mclock 2000,2000,2000,2000,2000 
miner work is 64%GPU load in all monitoring and no reset. -50W. When no -cclock -mclock monitoring 100% and can reset, +50W. Win10Anyversary

I'm mining with NVIDIA 1070 using the recommended driver on first page (anniversary update) for win10 64BIT.  but I'm only get 3.5MH for ETH.  What is going on? This is for MSI 1070 and Asus 1070.  4 different cards tested separately.

I'm having trouble using this miner with a 970 running win10. I am only getting half the hashrate I should be. I know its a known issue and I'm told there are solutions, however I cannot get any of them to work. I have tried several drivers that I saw recommended elsewhere. Is there a solution for this problem that works with Claymore?

 I saw 30 briefly with a 800mhs memory overclock, but it wasn't stable long-term.

 27 MH/s with a 300 Mhs memory overclock on my pair of Gigabyte Windforce cards right now, no other OC attempted and due to IRL issues haven't had the TIME to try to fine tune them more yet.

I don't think so. It was never an issue with older cards and I have excess power.


Like I said before, the rig won't even boot.


I'm going to purchase some decent powered risers, I'm now convinced it's a power issue derived from the fact that the 480s are sucking a lot of watts from the PCi-e bus.

I have 1060 3GB, gets about 18MH Eth and 300MH Sia, 19MH with mem set to 2000Mhz.  I think 1070 can do around 26MH Eth with memory OC. 

For LBRY, 1060 3GB does ~138, I have a small OC so getting ~148.  1060 6GB would be ~150-160 stock, 1070 ~240.

Just checked, you are correct, it's a bug with indexing. Intermediate build with the fix (cuda :
