Good price was offered for 10 Z9 units.   However only BTC advanced payment was accepted. No escrow or other method.

Yes. Very disappointing. My power cost is $0.062.   My Dell R815 generates 9.8 KS with XMRIG 5.01 for about 720 Watts of power. Four Opteron 6236 per machine. I plan to sell these servers.  At my power cost the servers are at breakeven but I expect it will get worse and there is no point running them.

Mine seem to be using a bit less power than yours. Not sure why. May be due to lower CPU clock speed.

Hello Again - How many threads and cores are you using to get 6866.8 H/s?

I now have Dell R815 Servers. Is it possible to overclock them?

Also I am trying to replace some 6176 CPUs with 6376 CPUs.   I naively thought they would work as they are the same socket. They do not.  I am using DL385 from HP.   Do you have some ideas on what I need to do to make the CPU work please? When I boot the machine I just get a red flashing light at the front.  No boot sequence. When I reinstall the 6176 everything works fine.

Thanks for the update. Lets hope RandomX is as profitable as expected.

I have two HP DL580 G7 Quad E7-8837 and have 5 R815 coming on Friday.

What I did not expect is that Windows 10 has a limit of 2 CPU!  So do CPU go unused.

How do you get around this problem? Which OS are you using?

Obviously Windows Server is expensive.

Thanks for your support.

Hello Doktor

I tried SRMMiner 0.1.5 on a 2 core Celeron machine. It worked first time on the RX.MINEXMR RandomX TestNet. No errors. I followed your instructions for enabling huge pages. That also worked. Performance was 7% higher than XMR-RIG. Great.

Thanks for the feedback about the Dell R620 server.   I started a fresh with your guided-setup.bat and used the RandomX testnet at RX.MINEXMR.

Unfortunately I got exactly the error codes as the first time + the second CPU is not being utilised.

I was able to utilise the second CPU by adding --cpu-affinity 0x555555 . That problem is solved. . Since the miner recognises all the threads and core automatically would it be possible to automatically set the miner up to use all CPUs?

Mining performance of SRBMiner 0-1-5 on RandomX at rx.minexmr.com was initially 92% of the hashrate achieved with XMRIG 4.5.0 Beta but when I ran it overnight hashrate exceeded XMRIG by 5%.  Not bad for your initial release.  I tried adding additional threads but it made no difference. Whereas XMRIG actually goes slower on these CPU when more than 1 thread per core is used.

The Celeron and the Dell R620 run Windows 10 Professional.

How about the binding errors? Do they matter? Perhaps additional performance could be achieved without these errors?

See links below. Thanks in advance for your help.

FOOTNOTE

I also have an R9 Fury on the Celeron machine. When I run SRBMiner 0.1.5 in parallel with Claymore 15 mining ETH I got a small speed improvement of 0.8% on Claymore 15! Claymore reduced the performance of SRBMiner on RandomX by 15% when run in parallel.

Hello Doktor


Thanks for the initiative. Single core performance on RandomXL seems good.  However there are some error messages thrown up and multi-core performance is poor at the moment. Can you help?  The test system is Dell R620 server with two Xeon E5-2620 V1 and 28 GBytes of RAM.

First the error messages:

Cannot bind database to node     Cannot bind cache to node    See https://drive.google.com/file/d/1o8AnMtIU3J9WstytBRktOa-L9f_C0BeN/view?usp=sharing

Cannot bind scratchpad to node    See https://drive.google.com/file/d/18G_bTBlkV3hUXC-D9X0sMrui1dSmjkFe/view?usp=sharing


The errors appear if I use the wizard to create the BAT file or make my own BAT file.

How can these errors be fixed please?

The performance issue seems to be that the second CPU is not utilised even though SRBMiner identifies 12 cores and 24 threads.

See pics from HWInfo of the two cores

Here is the command line used   SRBMiner-MULTI.exe --algorithm randomxl  --cpu-threads 0 --pool loki.miner.rocks:5005 --wallet L7f9SMpr43wNERBxCngFyqMoJvkMax8xSitiJY335ra12ucbiEFzgqKfHJg1Q9y58RGMi3TyGvPC94e 6w3zYKK9i9PHmDDr  --cpu-threads

Finally I can't see documentation on how to use CPU affinity  and   --cpu-priority. Please can you add it?

HELLO - Thanks for your feedback and concern about not being able to run other applications due to CPU UTILIZATION.

Actually I have the opposite problem.   CPUs are running at 58% and so I have plenty of spare capacity.  That figure includes running Google Remote Desktop without a problem.

So the CPU is under utilised. How can this be fixed please?

Task Manager show 58% CPU utilization: see  https://drive.google.com/file/d/13gGY6jBrF9qpCdjsxpRhlQPoyhpDsqS7/view?usp=sharing

Half the threads are unused. See https://drive.google.com/file/d/1d41Y5YaIscVGkg-kXfpSCYvZvuv_VAEu/view?usp=sharing


If I change the number of threads with '  -t  ' to say 13, 17, 24 or even 11 performance goes down and power consumption and CPU usage go up. There are 12 cores and 24 threads.

If I do not use a --cpu_priority with a value of 4 or greater the machine mines slower.

Is it possible to get more from these CPUs?

Thanks in advance.

Thanks. Did you see anything incorrect with the command lines I used for the Dual Xeons (see above)?

Also you do you think the Loki Hashrate is latent XMR hashrate? Ready to move across to XMR?

Hi. Do you have a planned release date for RandomX please?

THANKS BUT my test server (Dell R610 with dual E5-2620) produced almost identical results for Loki and XMR.

LOKI 3600 H/S see https://drive.google.com/file/d/1XM3l6UzTeQmfUlCQ9DJXco6y4hN1oJUt/view?usp=sharing

XMR 3700 H/S see https://drive.google.com/file/d/1M3u24W8GCo8yLrGZvFvFjmcr3T1SKBCP/view?usp=sharing

So are you sure that Loki and XMR have different hashrate results?

Perhaps I am doing something wrong.  Here are the command lines used:

LOKI: xmrig --url pool.hashvault.pro:80 --user L7f9SMpq53wNERBxCngFyqMoJvkMax8xSitiJY335ra12ucbiEFzgqKfHJg1Q9y58RGMi3TyGvPC94e 6w3zYKK9i9PHmDDr --pass x --keepalive --donate-level 0 --tls  --cpu-priority 5

XMR: xmrig -o randomx-benchmark.xmrig.com:7777 -u 47wcnDjCDdjATivqH9GjC92jH9Vng7LCBMMxFmTV1Ybf5227MXhyD2gXynLUa9zrh5aPMAnu5npeQ2t Ly8Z4pH7461vk6uo  --cpu-priority 5 --algo = rx/0

Can you see an error?

Thanks

THANKS. Do you think perhaps the 52 MH/S of Loki hashrate is latent XMR hashrate? i.e. machines that are commissioned and ready to move to XMR? The benefit of doing this to know the machines work and to make tweaks and test airflow etc

THANKS. Did you use anything else on the command line/config file or CPU set up? Or is it optimal to let XMRIG figure it out?

Thanks for the information. Do you think you will make any money mining XMR RandomX with servers? May be you would if you had very cheap power. RandomX is currently used on LOKI, a tiny coin with a daily exchange volume of $10k.   Loki's network Hashrate is 52 MHS which is equivalent to 30000 Xeon E5-2620 CPUs or 4700 of the new Ryzen 3900X CPU.     So that is a huge hashrate to get just $10k out per day.

THANKS for the information.   How much memory did you have installed for those E5-2640 and E5-2670 tests and how fast is the memory? Also which OS did you use?

The Gulden price has shown some signs of 'not going lower' since mid August 2019.   This suggests that all the talk on this forum about pools and miners dumping is not having an effect on the price.   When someone sells, someone else must buy.   So in this thread people identify the sellers.   Who are the buyers?

Hello Sir

Claymore 14.7 is working fine on a machine with two RX480 8GByte Red-Devils.

However Claymore 15 says        cudart64_100.dll was not found

This occurs immediately on clicking start.bat   and no log files are created.

I am not running any Nvidia Cards.

I am running Windows 10 Pro with 8GBytes of RAM and and Intel G4400 CPU 3.3 GHz. Its a Gigabyte H170 motherboard.

Windows 10 version 1803 and build 17134.1.

Radeon Drivers are 24.20.13011.1009 with date 27/08/2018. They are patched with driver patcher.

How can the problem be fixed please? As I say, Claymore 14_7 runs fine. So v15 should work

Adding    -platform 1     (for AMD) makes no difference.

Hi

Do those Acorns work in GPU assist mode yet?

What mining s/w is available for the Acorns?

Hello Mr Scott. Can you confirm the shipping date more precisely please?
