Re: SRBMiner Cryptonight AMD GPU Miner V1.9.1

Hi Doc, I find out that my Vegas 64 are all stable at memory tweak profile 8. How to apply it so it is already at 8 when restarting the miner, instead of manually pressing the + sign. Thank you

Try adding "tweak_profile" : 8 in config.txt, for example :

Code:

{
"cryptonight_type" : "normalv4",
"intensity" : 0,
"double_threads" : true,
"off_temperature" : 80,
"tweak_profile" : 8
}

Thanks Doc, for your fast response, it did work like a charm. But I will have to ask one more question though. Maybe i was thinking to do a fine tuning and isolate the weaker cards and put them one profile 8 and the rest on 9 or 10. How to do that? And last thing after updating to the latest SRB miner 1.9.1 I found out that it restarts the miner after 5 bad shares. One of my Vega VII apparently inst from the silicone lottery. I have memory at 1075 and clock at 1700 to avoid too many bad shares. I still get one bad share from time to time but its not a big deal, because I still get about 99.5%, but my question is how to disable the new option of restarting the miner after 5 bad shares or maybe to increase it to 20, in order down time due to restarts. I think I have 3-9 bad shares per 24 hours from that GPU. Thank you so much!

For per card configuration use gpu_conf array, here is an example :

Code:

{
"cryptonight_type" : "normalv4",
"intensity" : 0,
"double_threads" : true,
"gpu_conf" :
[
{
"id" : 0,
"intensity" : 112,
"worksize" : 16,
"threads" : 2,
"tweak_profile" : 8
},
{
"id" : 1,
"intensity" : 112,
"worksize" : 16,
"threads" : 2,
"tweak_profile" : 10
}
]
}

You get the idea. Also on the first page or in the readme.txt you have more info.

Regarding the restart on 5 bad shares, well yes, i don't know myself why i didn't make that one optional Grin

I will add a parameter that disables this in the next version in a few days.

God Bless, you are amazing!
