Why was support for older cards removed?

Although those cards are really old, the real reason for removing support for Pitcairn, Tahiti, Hawaii, Fiji and Tonga is that i don't own any of these GPU's, meaning i can't test / optimise any code for them.

Oh, no!! Not the Fiji, they are good and have RAM speed (HBM1).

Can you reactivate the the Fiji ? I ask for a good friend.

Thanks. 

Hi doktor83,

do you have a link for checking the mining on pool1.dynamocoin.org? My console summary is 11 MH/s (all GPUs) with your new version 0.9.2 but i will see it in real !!!!!

Thanks.

Hello OBTC developers and inventors,

i have a few questions.

Why are hardly any found anymore?
Why do transfers take so long?
Why should everyone manually switch to woBTC and why doesn't a new client wallet do that in future?
Why is it allowed that unknown pools with over 1T_Hash and more work in the network?

What is wrong with your coin and the network?

I would be very happy to receive an honest and timely answer.

Thank you. 

Hi,

how can i mine on a multi-gpu (4x fiji) system with one instance?

Miner -> pow-miner-gpu

run_config.ini:
...
GPU_ID=0
GPU_PLATFORM_ID=0
...

Only one gpu will use from 4. At moment i have four instances with different GPU_ID (0 to 3).

for info: mining power for one fiji is round about 520 MH (boost_factor 1024).

Thanks for help.

Hi,

me again with the Vega64 and heavyhash problem. It works round about 4min and then... (on two different rigs with Vega's)

Hi,

Vega64 works again with 0.30.8.1 (heavyhash), Nice job. You are great.

Thanks.

Hi,

Version  0.30.8 doesn't work with my AMD Vega64. A second RX480/8GB is also in the rig. Problem is -> low difficulty and rejecting from server.

I checked it with driver 20.3.x and 21.11.3. (Windows 10).


Difficulty by the Vega is 27 and the RX480 23 (auto setting).


All works fine with 0.30.6.


I hope it no big problem for the next versions.


Thanks.

Hi doctor83,

the version 0.6.9 does not work with 2x Fiji (Radeon pro duo, 0.6.8 is ok). I try normal and admin mode. CPU mining is disables (5950x).

Question: is it right, that an AMD 5950x 16 core cpu (32 threads) only reach 14 MH/s (huge pages is enabled, 32 GB Ram)?

Thanks. 

Hi doctor83.

i have problem to mine ERGO (srb version 0.6.6) with 2 VEGA-64-LC (8 GB). It is not possible to mine more than 18 hours. After this time the cards need an reboot, because they can't reinit with a new instance -> mining stops. 

Can you look. i know such problems when using timer (seconds clock) with only 16 bit resolution -> 16,8 hours -> overflow.

My driver version is 20.10.35.02 with HBCC ON (max) -> 2x230 Watt -> 225 MH (woolypool).

Thanks.

@herominers -> since 6 hour no block found !!! Global hash about 1TH ?? where is the pool with so many users?

Thanks.

Hello andrucrypt,

i reduced the mem clock to 945 MHz. The first calculation do the "result rejected, low difficulty". The probleme stay for me (radeon software 20.10.35.02 - old design). If you have time (in future), it would be nice that your software works well for me. Thanks. 

Wild Rrig (0.28.1) makes at the moment with Firo (zcoin, MTP) just too many problems (low difficulty result). I am therefore on another engine. The hashrate is also ~20% worse compared to the competition (0.55 vs. 0.72 firo per day).

I use it with (2 x Radeon Vega LC, -18% Power, 1000 Mhz Ram, ~1320 MHz clock)

wildrig.exe --print-full --algo mtp --url stratum+tcp://xzc.2miners.com:8080 --user my_wallet_adress_is_not_for_all.1 --pass x --donate-level=1

Can you check this?

Thank you.

it correct, that the donation is 5 % for the new algorithm? -> minotaur?

Hello KL,

xevan hashrates (doesn't work with all cards yet):
...
Vega: N/A (HW errors)

...

it does not work with VEGA64 (4.4MH/s but nothing will be found), same with Fiji (1.8MH/s).

Do you working on it?

Thanks.

Hi,

XFX VEGA 64  LC 8 GB -> 6300 kH/s (default parameter -> 380W)

....reduced to

-25% power
1400MHz Core@950mV
1060MHz RAM@950mV

= 5950 kH/s (230W)

all with zjazz-1.1-amd-win64

yes, i go back to monero: all together 9500 H/S @ 1550 Watts

lolminer results 0.43 with my undervoltaged amd cards ->> BTG

Vega 64 LC (XFX) = 35 sol/s (PWR= -30% / RAM = 1060MHz) (2 pieces = 510W)
RX480 (XFX black)= 18 sol/s (CLK=1160 P-Stage=4) (4 pieces = 490W)
fury (x -> **) = 25 sol/s    (** 2 x pro duo = 4 x fury = 100 sol/s @ 670W >> undervoltage 950 MHz/-25%/1,05V)

not profitable, all together need 1670 Watts (2x Vega 64 LC + 4x RX480 + 2x Radeo Pro Duo =>> 270 sol/s).

Soldering is kid stuff. Do not frighten him. A good soldering station Ersa, Weller -> 80-150W) and the thing is outside. It is more important which value should be clean again. Maybe you look for pictures from the graphics card -> reference design and it looks like Potent was the original -> Dimension. It could possibly only be a 100nF-16V (25V). Maybe you look for the chip (CODE), where this capacitor belongs. Just a few suggestions ...
