Turns out you have to use static difficulty with ccminer 2.0. I'm using diff 0.01 and it's reporting 65MH/s. Pool is reporting a similar hashrate.

ccminer 1.2-x15 is ~20% slower than 2.0 but works well with VARDIFF.

I can't get to 70MH/s even with GPU clock and voltages tweaking. I have a Zotac 1070 Mini.



Well I was not using 2.0 because it crashes my rig. But in fact 0.01 fixed diff works for +20% hashrate

Chaps is it possible to mine Digibyte-Groestl with ccminer 2.0 with Nvidia GTX1080 and Windows 10 x64?
yes, but you'll probably get only half speed that miner shows ))

Why? Which miner is recommended?

I'm not sure I have the best answer, but I tested quite a lot of ccminer version, and I got best results with ccminer-1.2-X15 (this is djm34 branch),
50-55Mh/s per 1070 confirmed on pool side.

Can somebody save me from experimentation please?
LYRA and Lyra2RE2. Do they differ from equihash regarding OC?
High core, low memory, low power limit?
How low/high?
I

I tried Lyra2RE2 the other day, it seems less bound to memory, I did not see much difference with stock mem and +800 in AB.

I understood he's developping opencl version of excavator. I may be wrong

he's developing opencl version for AMD cards

Ok, do GPU Mem errors shown in HWinfo affect the number of found shares ?
I mean more errors mean less found solutions, or it has nothing to do with it?

 In my experience,If error in the millions, yes. usally you can see share rate decline and eventuelly a crash a the end.

Good job, neighbour, now I can change my vddc without using HxD Cheesy

Altough it's working, i don't know why it won't "take it down" to the entered value if you are below 1V.
A value has to be changed somewhere more, but atm i don't have enough time to play around.
Setting the desired value and then running WattTool and just pressing "set" at the mem p1 will change it to the desired value.

Have to find what value does that actually change thru i2c.

Actually, sometime it works without touching anything.

This morning my rig rebooted and when I started wattTool, voltage was already set...

Hello,
I gave it a go to test the default voltage function. It works well with RX 470 and RX 480. Although the voltage may vary (not much) from the chosen value.

I too noticed connection pb with ethermine and devFee.

@Zawawa: there must be something not working well with devfee, because if you look at your adress on ethermine you can clearly see some people are/try mining but there's to few share's.

I just uploaded a new pre-release:

https://github.com/zawawawa/gatelessgate/releases/tag/v0.1.3-pre6

I managed to add another 1Mh/s to Ethereum minining with GCN3 devices, including Fury, Fury X, Nano, and RX 470/480. I believe power consumption is slightly reduced, too. Please let me know if that is actually the case.

Having said that, I also had to add a voluntary 1% developer's fee for a number of reasons. I am not going to get into boring details here, but it suffices to say that I love open-source development and I would like to make it work. I trust your good conscience.

I started GG pre6 on win7 before running to work. I could'nt play much with the settings but here what I saw in 10 min:
- Had to drop xI to 1024 because the default 4608 was crashing my cards, had no time to try something else.
- got the same hashrate than pre4 (but no optimised xI)
- fan speed was lower, wich could indicate less consumption, but the test was not long enough to be accurate.
- Once I arrived to work, the rig seems down.

Edit: I finally connected to the rig and it was working fine after 8 hours.

At any rate, I will have to rethink the financial aspects of open-source miner development.
Sadly, I was making much more money when I was developing private kernels just for myself.

Well, you should add optional devfee to your miner( on by default), I'm sure a good percentage of miners would pay.
112  Alternate cryptocurrencies / Mining (Altcoins) / Re: best Polaris sgminer eth options? on: March 31, 2017, 05:15:50 PM
that may be why on the pool side I had bad results. Hashrate is not all that counts...

I turned back to claymore, dual mining is currently better as long as DCR price is good.
113  Alternate cryptocurrencies / Mining (Altcoins) / Re: best Polaris sgminer eth options? on: March 31, 2017, 12:24:37 PM
Hi,
I run worksize 256, it gives me better hashrate than 192 on both hawaii and polaris cards all of them 4G.
As xI I tried a lot but could'nt get anything better than with 4620.
And 2 threads was better than 1.

With default setting from your .bat, on polaris cards I'm very close to claymore on eth, but my 290x is almost 3mh behind.

Yes.  Here's the stock Hynix H5GC4 1625 strap:
999000000000000022559D0010DE7B4480551312B78C450A004C0601750414206A8900A00200312 018112D34A42A3816

And here's what I'm running at 2025 (stable after >24H):
999000000000000022559D0010DE5B4480551312B74C450A00400600750414206A8900A00200312 010112D34A42A3816

What speed do you get on rx470 with Hynix with 1625_modded strap on 2025?

Now i'm using 1375 strap on my Sapphire ref-like rx470 4gb with hynix, 1140/1950 28.4mhs (rock-stable)
(Claymore under windows)

I get 28.2-28.3 with sgminer (kernel 4.10.5/AMDGPU-Pro 16.60).  With Claymore ~28.9Mh.  Sgminer should be just as fast once I finish tuning it (or worst case wait for Wolf's Polaris-tuned ethash kernel).
With the ref-style Sapphire should should be able to get over 2000, maybe even 2100 if you mod the 1500 strap.


With the first 1625 strap you posted a few days ago, I get 29.7 core1150/mem1950 on rx480 4g hynix.
the strange thing, is this number don't change if I change memclock up to 2100... It's like the memclock is bloqued on 2050 and what's showed on screen is a lie!
(I failed to post screenshot)

It's based on the 1625 strap, since the 1500 strap wasn't stable for me beyond 1875.
That's very strange, I have several rx with hynix and the 1500 strap is the most stable at least up to 2050.

Maybe your cards have better cooling for the RAM?  This is an Asus Strix.  After tuning the 1625 strap, it was stable at ~27.2Mh with a 1950 mem clock.  Now I'm testing 2000.

I may try your strap on a gygabyte rx 480, VRM stays very cool on that card. I'll let you now.
I was able to run it at 2050 mem clock, compared to 1500strap I went from 29.4 to 29.7 but with more memory errors.

If anyone is using SGMiner-GM with Windows to mine XMR with a RX 470 or RX 480, I would appreciate posting your h/s.  Thanks.  Thinking of picking up a few.

I tested Gygabyte G1 rx 480 4G => 860H/S. But no idea if stable long term, it was just a try.

it's in zawawa's signature just before you're post
