Topic: SRBMiner Cryptonight AMD GPU Miner V1.9.3 - native algo switching - page 103. (Read 237247 times)

Absolutely no complaints, just results. In my case, for tahiti the most productive version is still 1.6.8, 1.6.9 is a little slower, 1.7.0 much slower. ( same settings, algo v8)

Nice hash rate, what’s your miner settings? Did you modify your mem clocks?

I just noticed that the nanopool linked new Finminer,, so I gave it a try. It sets up easy, but in the end I'm getting the same overall result. While Srbminer gives 1700h/s on one GPU and 1000 or less on the other, in Finminer both are around 1300h/s. Well,  I guess that's it, eh?

Need more info, like is it stellite only or EVERY algo? same settings? what have you tried beside running new version with old config ?

I dont have every possible gpu to try out when coding, sometimes what pushes one card, takes off another, so dont be immediately mad bros 

Hi i got  less hashes with 1.7.0 on my tahiti too. Can you share your 1.6.9 miner settings for pitcairn? Thank you.

Thank You very much ,Sir

Did you bios mod your cards? Did you use soft power play table? XMR-stak did not work anymore for me so I am trying to use srbminer now. Any link or pointer would be appreciated.

HELLO !!! I use the 584 and 574 amd cards and have some cn8 hash improvements about 10 hs per card! : ; D nice!
but I also have some strange explorer behaviors when I click on SRBMiner-CN.exe to copy/past it - I get laggin explorer and crashes it about 1 minute later. Is this a miner mistake or a problem on my part: - [
1.6.9 and 1.6.8 have no problems
I excluded SRBMiner-CN.exe from my antivirus but it did not help. Antivirus also recognized one more danger than 1.6.9-1.6.8

Hi dok,

I would appreciate if you could add 'reported hashrate" just like Jce.

Thanks

And what is for heavy / bittube2 algo?

Also, did someone test fragments and bralock, if I understand correctly fragments is more important parameter to tune?

Interested in settings for bittube2 algo for RX 570 4GB, Vega 56, Vega 64

"fragments" : 0,1,2,4,8,16,32,64 or 128. It can boost your hashrate if you find the right value for your GPU
"bralock": 1-256, parameter to tune, it *may* add some extra hash, it can differ between algos

I:58 T:2 W:16 F:4

All settings for SRBMiner are the same for each Vega 56 and done in the V8 config file:

intensity: 112
worksize: 16
threads: 2

Vega 56's #1, #2 and #3 are in one system that has Radeon Adrenalin Edition 18.8.1 installed which actually produces high hash rates than the recommended Radeon Adrenalin Edition 18.5.1 installed in the system with Vega 56's #4, #5, #6 and #7.

These two systems are on a Biostar H81A motherboard and are using a single HP 1200 Watt Server Power Supply (87% Efficient) with a 17x 6-pin Breakout board. The motherboard is powered by an 180 watt Pico PSU that gets it's 12 volt input from a 6-pin connector on the breakout board. I like my systems only running on a single power supply.


System one is hashing on an  i3-4340 at 73 H/s and system two is hashing on an  i5-4570 at 195 H/s.

All power measurements are done at the wall with a Power Usage Monitor. That way the entire system is measured (motherboard, processor, memory, ssd) and the Vega 56's and it is the real power not the incomplete ones that only look at the software measurements like HWINFO which does not consider the inefficiencies of power supply and internal power conversion circuits or the rest of the system.

Realize that V8 is much more power hungry than V7 was.

I do not use soft power play tables as I have found that V7 and V8 basically run between P6 & P7 states on the core and P3 on memory. The Vega 56's are reference designs of various vendors with stock BIOS.

So my Wattman settings for six of the Vega 56's are:

Core:
Min P6 1212 MHz @ 905 mv
Max P7 1452 MHz @ 925 mv

Memory:
Min/Max P3 935 MHz @ 900 mv

Fans:
Min: 2700
Target: 4900

Temperature:
Max: 75
Target: 65

EDIT: I forgot this setting. I needed to do this +10 as a few of the Vega 56's clocks were only in the high 1200's MHz and not the 1350+ MHz they should be and were flicking between P6 and P7 state.. It turned out those were being power limited. So be sure to do this setting also.
Power Limit +10

I do have one problematic Vega 56 that I have to run at:

Core:
Min P6 1212 MHz @ 960 mv
Max P7 1452 MHz @ 985 mv

Memory:
Min/Max P3 900 MHz @ 950 mv

With all that out of the way here are the final numbers:

System one 3x Vega 56's:

Vega #1 1911 H/s
Vega #2 1893 H/s
Vega #3 1904 H/s
--------------------
Total  Vega's 5708 H/s
i3-4340 adds 73 H/s
-------------------------
System Total:  5781 H/s

Total Power at the wall: 675 watts


System two 4x Vega 56's:

Vega #4 1869 H/s
Vega #5 1865 H/s
Vega #6 1874 H/s
Vega #7 1863 H/s
--------------------
Total  Vega's 7471 H/s
i5-4570 adds 195 H/s
-------------------------
System Total:  7666 H/s

Total Power at the wall: 898 watts

What are the settings for rx570 4Gb for v1.7.0 and v8?

11hs less for 1 card that lot of money lost lol

My Vega 64 gained 12H/s vs 1.6.9 on v8. Stable at 2134H/s, power consumption remained the same.

6*vega 56
CN lite V7

srbminer 1.6.4 = 25500HR
srbminer 1.6.9 = 25650HR
srbimner 1.7.0 = 25580HR

Can You share ,settings and configuration,please.

So, I tried to change different settings (i,w,f,k,t) and nothing helped (algo Haven). SRB v.1.7.0 for RX564 (with mod bios) much slower than SRB v.1.6.9    
But for RX574 SRB v.1.7.0  (with mod bios) much upper than SRB v.1.6.9    

play with fragments (its enough to try 0,1,2,4,8,16) and see which one gives the best results for that particular card.
also try aes 0,1 or 2 .
Fast algo is V7 variant nothing has changed in code for v7 and variants
my guess is that the default fragment value isn't optimal for your cards.

also in the next version i will also return the 'old' code for heavy, that was in 1.6.7, and some of you say it was better for you than the one now.
So with a new parameter (yes, again), you can choose which mode for heavy you want to use.

That way everyone will be happy 

On 1.7.0 I am getting better hashrate
my rx 580 4gb get about 10 H/s more on v8 (from 990 to 1000)
but my rx 570 4gb get about 40 H/s more on v8 (from 945 to 985)

For 5 cards (3x570 and 2x580) my hashrate went up for about 140 H/s compared to 1.6.9 with same settings but power consumption also increased for about 30W (from 630W to 660W).
Also my 570's are getting to much memory errors now, so I will need to lower intensity on v8.
For fast algo I am getting about 200H/s less compared to 1.6.9. with same settings.
