Code:

--icarus-options 115200:1:1 --icarus-timing 3.0=100 --rock-freq 290

Please please please don't use icarus options, they're designed for an fpga that hasn't been used in 2 years. If you see any documentation anywhere recommending you use them on a modern device on the current official cgminer, the advice is outright wrong. Even the use of icarus timing is misguided. Just remove them.

Code:

 4: LIN 0       : 290MHz  44C             | 32.87G / 35.03Gh/s WU:489.4/m A:84266 R:2680 HW:3183
 5: LIN 1       : 290MHz  42C             | 34.15G / 35.16Gh/s WU:491.2/m A:90893 R: 536 HW: 356

is there any way to fix this?

Your hardware error rate for LIN0 is 3183 / (84266 + 2680 + 3183) which is 3.5% and nothing to worry about, and much lower for LIN1. Your problem is your monitoring software is broken and reporting nonsense, not your devices or cgminer. You are overclocking them a bit though, but provided they're still producing good shares, even 5% HW errors are nothing to worry about.

thank you, i notified the minera guys of this error ...

without knowing much about the RockMiner R-Box here I am guessing the "--rock-freq 290" is some type of chip clock setting Huh

? If so maybe play with that setting and dropping it back....

Line of thinking the more ya OC the harder the unit works throwing more HW errors.... <<<< just thinking of antminers I know with them the more ya OC them the higher the HW are

retried without --rock-freq 290 and got like half the hashrate and 47% HW errors

hmm I hope it's only a display error because while monitoring the screen output on console

the HW value seems pretty low in camparison to the Accepted value

just a quick look at this it the 2x RockMiner R-Box that are the problem not the asic erupters just off the sreenshots

Do you have a fan blowing on the block erupters? If not they will be incredibly hot...

maybe your HW OverHeat .

44°C max so far and I don't think this is all it needs to overheat?!

Hello everyone,

I never really payed attention to the HW errors on my miner. But while setting up my own Mining with Raspbian I noticed that I got over 70% HW Errors. Then I switched to Minera yesterday I noticed that I still got over 50% HW Errors even though I use

Code:

--icarus-options 115200:1:1 --icarus-timing 3.0=100 --rock-freq 290

on my cgminer, I tried bfgminer but I didn't even get near my max hash rate.

My Rig:
Raspberry Pi with Minera OS
2x RockMiner R-Box
4x ASICMiner Block Erupter USB
CGMiner v4.5.0

Output cgminer:

Code:

and here is a screenshot of the Minera Dashboard

It runs fine but like you can see I got many HW Errors.

How cgminer is started:

Code:

/usr/bin/screen -dmS cgminer /var/www/minera/minera-bin/cgminer --icarus-options 115200:1:1 --icarus-timing 3.0=100 --rock-freq 290 -c /var/www/minera/conf/miner_conf.json

and my conf file:

Code:

{
    "api-listen": true,
    "api-allow": "W:127.0.0.1",
    "scan": "all",
    "log-file": "\/var\/log\/minera\/cgminer.log",
    "pools": [
        {
            "url": "stratum.bitcoin.cz:3333",
            "user": "",
            "pass": ""
        },
        {
            "url": "stratum+tcp:\/\/multi.ghash.io:3333",
            "user": "michelem.minera",
            "pass": "x"
        }
    ]
}

is there any way to fix this?
