@all Do not use blockchain driver anymore.. ever.

Hi,

it was little bit hard to understand your examples how to put different straps and clocks to multiple cards.
Got it after time but you could put better example to readme.

I think the straps for Samsung are the same as Ubermix because i got same results but the hynix straps were better
than mine.

RIG 1: (900w from the wall, 6 cards)
-Sapphire rx480/8G (Samsung), -strap 1@2050, 30,5Mh/s,(AfterBurner, CoreV -100, Power -40%, CC 1050)

RIG 2: (700w from the wall, 6 cards)
-Gigabyte rx470/4G (Hynix), -strap 1@1930, 27,5Mh/s, 4 cards. (AB, CoreV -98, Power -20%, CC 1050)
-Sapphire rx470/4G (Samsung),  -strap 1@2000, 30Mh/s, 2 cards. (AB, CoreV -98, Power -20%, CC 1050)

I hope rigs are stable now, they have been running now for  24h.

Both Claymore 14, AMD 19.4.3.

Thank you again

May be you are right...
"-strap X@YYYY" - X - strap index, YYYY - memclock, that is all in general

RIG 1: (900w from the wall, 6 cards)
-Sapphire rx480/8G (Samsung), -strap 1@2050, 30,5Mh/s,(AfterBurner, CoreV -100, Power -40%, CC 1050)

You can try "-strap 3@2050", it's a bit faster for me.

Support for Vega straps is almost ready, I will release new version in a day.

PS. Not sure if I should also add support for old AMD cards before working on Nvidia...

Ok, thanks, i'll try... Usually it isn't worth risking the stability for couple %.
how low can you go with power consumption with these cards without losing the hash?

Hi!
RX480/4Gb Hynix + 4xRX470/4Gb Hynix, ~30,8MH/s=~154MH/s, 1150/2100MHz on v12 & Blockchain driver. Should I upgrade to v14 and install 19.4.3 or change the settings?

[RuMiner]

I've updated all my rigs to 14.0. Polaris runs with no change (I didn't update blockchain drivers to test straps yet), but Baffin core (RX460) lost up to 10% hashrate.

It seems v14.0 cannot apply overclock sometimes for blockchain drivers, I will check it. It seems a lot of people still use blockchain drivers...

I don't see any reason to change something in rigs stable working for more than a year.

with 18.6.1 drivers have error

GPU #0 strap "POL4H3" failed: unsupported video driver, install recent AMD drivers

Ok, I fixed this issue.

Yeah I got a few reports about it, fixed in upcoming version.

I am getting a hard reset everytime I try any of the straps. I have testing mode enabled, secure boot off, driver 19.4.1 installed and 8 hynix rx580 8gb cards on win 10. When it goes to apply straps, it gets to the point where it shows the strap has been applied to the 2nd card and then...boom, reset. Tried with all levels of strap (1->5). I am setting the clocks with overdriventool externally, at 1751mhz (pretty low for testing sake).

Try to set 2000-2001MHz. And set voltages to default.

How do the miner know what straps that are best? I have the same cards just with different memory brand.
I already have 31.8 on all cards. Will I get more now?

[evlo]

by memory id omfg

[Bigdrago]

My oc settings are tuned from what my straps are today.
Will claymore notice my oc and then apply the best straps to void errors?

out of curiosity i tried 14  beta on 1060 rig and it does have worse hashrate, even hashrate reported by miner, then ethminer, on windows

Have you tried to copy files from CUDA10 directory? In next update miner will use CUDA10 by default.

[Geniusvzla]

good lord, Claymore, I have rx480 8 gb samsung, using latest 14th ver and reaching only 28.8mh/s, any help to see those 33mh/s?

I use "-strap 1@2250" or even "-strap 3@2250" for these cards, read Readme for more details.

Hi Claymore what is the maximum strap number we can use? Above is 3, and I see in other of your posts 4.
Can we go beyond?

i have tested saphire rx480 8gb samsung with -strap 1@2250 and make 32.4 Mh but the only problem is that apears allot of GPU Memory Errors on HwiNfo
Claymore you don't have any errors with mcclock 2250 ?

Hello, my platforms are conformed by GPU rx580 8gb Hynix, and with this new Version 14 Beta although if I manage to reach 33 Mh / s with -strap 3 @ 2250 the memory errors are catastrophic. I have not seen any comment in particular from Old House. I would appreciate any comments from you that will make reference to these errors and if there is any improvement in the next version, thanks

I tried it after this post and it is almost same with cuda10.
