Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[LucianoBM]

v11.2:

- some improvements in AMD GPU kernels, it can increase hashrate a bit in some cases.
- reduced some delays, it will cause a bit less stale shares.

Thank you for the updates!!

This time I had a decrease on 2 MH/s on each RX 570 (I have 6 on this rig).
Any idea why?

I have same problem, try to increase dcri up to 40
It works in ETH-only mode

You perhaps need to readjust -dcri for ETH-only mode, use "+" and "-" keys for that and "s" key to see current speed. You can also try "-asm 2" option with various -dcri to see if it is faster.

the hashrate has gone up !! perfect : )

[Vann]

from 30.2 to 30.5 but we will se if there is less stale shares..

It depends on the memory type. Even with good timings Samsung is hard to overclock over 2050 MHz stable and Hynix/Micron can easily overclock to 2200-2250 MHz depending on the memory straps and ASIC quality. The best you can do is find/buy optimized timings for your memory type.

but samsung can be more undervolt. you can lover voltage more on samsung then other 3

Undervolting the memory has very little effect in power consumption compared to underclocking and undervolting the core. Undervolting also depends more on ASIC quality than anything else.

Excellent update, Claymore.  Each of my rigs, depending on the cards have collectively reported roughly 1-3 Mh/s more.    Thank you!!

Hello guys! I have one problem I set my 580 8GB rigs to do dual mining on black2s with an dcri 45 and I don't have any hashrate drops from ethereum but when I try to set the cards 580/570 with only 4GB I can make a proper settings to don't have drops on my ethereum hashrate evan if I set dcri to 20.. How we can set the 4GB cards to don't have drops? any idea guys?

With dcri 20 I still have less with around 10-5 MH/s on 6 570 4 GB cards. Thanks!

Nobody have this issue guys? Maybe you Claymore can help me with this...

Are you running the 4gb cards at same core clocks/volt/power limit?
Monitor for temperature, clocks, volts, power consumption using HWinfo64 and compare 8gb card with 4 gb card.  Will provide more insight on what's going on.  Perhaps, just one 4gb and one 8gb card running and have a screenshot of miner + HWinfo64 sensor information of these two cards shared here and we can help.

Great job with the miner Mr Claymore, but i have a question, as of now i use v10.0 on my rigs (22 Nvidia 1070 FE), im mining on nanopool i have reported hashrate 710 and calculated 735-750Mhs at 1-3-6-12-24h, if i try any other update over 10.0 with the same exact clocks i get 710 reported and 690-705Mhs calculated. any ideea why this is happening?i have none.

rigs:22 Nvidia 1070 FE, 3xAsus prime z270A,4gb ram each, CPu intel 4400,3x evga PSU 1600W.
thanks

preliminary results of v11.2

reported hashrate up 0.7%
rejected shares up 0.8% from zero

stales (too early to say definitivaly) but up slightly.

At this point looks net slightly worse for me.

Guys is there a way to mod a RX580 so it can mine eth ath 2000+ mclock? everytime i go more than 2000 memory speed windows crashes. Is there a way to add another memory strap at 2250?

Sure, with RX 580 Gaming X 8G, Ellesmere, hybrid Hynix/Samsung memory and a simple bios mod:

1:1750 > 1:2000
2:1750 > 2:2000 & 2:2250

-cclock 1250

-mvddc 925
-mclock 2225

Thank you @AnViGo and @Claymore

I use this:

-powlim 15,15,15,15,15,15 -cclock 1150,1150,1150,1150,1150,1250 -mclock 2050,2050,2050,2000,2050,2100 -tstop 85,85,85,85,85,85 -tt 64,64,64,64,64,64 -fanmin 30,30,30,30,30,30 -fanmax 100,100,100,100,100,100 -asm 2

I see that -dcri default is 30.
On v11.0, any value of -dcri between 20 and 90 keeps the hashrate very very similar as -dcri 30 (around #0 29.7 / #1 28.6 / #2 30.

On v11.2, -dcri 30 keeps the hashrate 2MH/s lower and increase while I increase -dcri
Between -dcri 40 and 80, it increases 0.1~3MH/s on each gpu (around #0 29.8 / #1 28.9 / #2 31.0) and 2 GPU hangs 2 times while I was typing this post

Any idea what I can do to increase it a little bit?

Thanks in advance!

The 2000< MHz timings are not Samsung timings they are the secondary memory timings on cards with a dual memory Bios.

[Metroid]

I remotely installed the 11.2 on my friends pc and is terrible if you disable dual mining, for example, during afternoon is blazing hot so usually turn off dual mining and when it turns dual mining off, is bad, had to reverse to v11 and this is my first time i reversed it. And to mention, 4 out of 8 gpus crashed after dag creation and only lowering the clock core a lot could make them to work again. So back to v11 on that pc and, @claymore you should investigate why updating the kernels brought such drawbacks.

Can this be done with the Nitro+ 4GB elpida? i mean the supstitution of memory straps should work on every gpu right?
i will try the voltage settings and get back to you. thnx dude.

[wip]

Latest version gave a nice small boost (v11.2), i will have the program running for 24hours and revert or change command lines.

When i use version 11.2 instead of 10.6, i lose 1mh/s per card and they also consume less power (7-10W/card)

to me it is not so great:

windows 10, 5 sapphire RX580 8GB pulse - hynix memory, blockchain driver

One question guys, i am using -ccvdc 870 but it looks like hwinfo shows GPU Core Clock 900mv
Why my gpu volatege set in claymore is not accepted?

You're using the wrong driver for RX 570/580's on Windows 10 v1709. The current AMD drivers in compute mode are optimized for Windows 10 v1709 FCU. Those are the fastest drivers to use with RX 570/580 cards. The only reason to use the blockchain drivers on Windows v1709 with RX 570/580's is some old miners like SGminer don't work with the latest drivers.

Just because you set a voltage doesn't mean the card will accept it if it's out of spec for the card.
