Neoscrypt rate drops to 1/4 after a while on 2.0.1.9

[ilgrank]

Hi Since 2.0.1.8 and 2.0.1.9, I'm experiencing a weird problem. I have a mildly OC GTX 1070, which is capable of 1.06MH/s on Neoscrypt.

Since the last two version,after some seemingly random time, hash rate drops to 200-300KH/s, while GPU usage, GPU frequency, and Memory frequency remain constant.

Again, I have been monitoring Temperature, GPU & Memory frequency and the loss of hash rate is not reflected in a reduction of those.

NHML does NOT exhibit this problem (same Rig, just switching from NHM to NHML)

there are also other people lamenting the same issue in the Reddit release thread, such as -this- but no one seems to care since the issue is seemingly hitting just a bunch of people

[Ankittygi]

I’m also facing the same problem since last from 2 to 3 weeks. Straight After 2.0.1.8 and 2.0.1.9. One month before I started crypto mining with GPU 1060 6 GB, 1050 ti. When they were performing well with giving around $6 (0.00052393 BTC) in a day but now after 25 days later my daily estimated earning are gradually decreasing and just only generating $3.5 to $4 .. why its happening I’m totally confused and lost here ..Does anyone else have this problem..?? ..please help to get rid of this problem.

[ilgrank]

Sorry but this seems NOT the same problem.

The rewards for cryptomining lowered a lot in the last month, and it is not Nihahash's fault. Lower rewards for given hashrate = less money.

You should take a look at your hashrate. If it is the same, you're NOT having my same problem Instead, if your cards had an aggregate hashrate (eg) of 990KH/s and that's lower now, that's my problem and your problem too :)

[Ankittygi]

Yes exactly around 3 days before my hashrate was aprox 1.039246 and now 981KH/S it is still gradually decreasing.

[ilgrank]

The drop other people is experiencing is both more pronounced (From 1060KH/s to 250KH/s) and can be temporarily solved by just closing and reopening NiceHash.. is this your case?

No, it’s seems like a permanent. In my case Low hashrate is remain same after closing and reopening NiceHash...i do not understand anything..is there any suggestion to resolve this problem Because it annoying and frustrating.

[ilgrank]

So definitely you're experiencing a different problem, I suggest you to

1) Try Nicehash Miner Legacy and check if the hashrate (using the same algo) is different

2) If the above has the same rate, (NHML 1.8.1.6 code is an older branch) then most likely you're having another kind of issue. In this case better try your video cards on another rig and check the results there.

Thanx for you valuable suggestion.

Ok first I’ll try NHML and after that i will go to the second rig for video card testing to know that how they perform on another rig.

[Ankittygi]

Thanx for your valuable suggestion....

[ilgrank]

Let us know how it goes 😊

Rolling my Nvidia driver to 388.71 fixed this problem for me. Equihash and Neoscrypt would be cut to ~40% on the newer drivers randomly.
