Re: SRBMiner Cryptonight AMD GPU Miner V1.8.9 - native algo switching

hey doktor, can you share the default intensity and work size for some of the algos SRB miner support? or is there some way to find this info?
I ask because I want to set the gpu_conf manually for multiple algorithms. There's some kind of bug that when changing algos one of my cards don't keep the minimum 3000 RPM, going to 900 RPM and making the card go to 100 oC. that is solved by setting the target_fan_speed manually but then I'd need to know the rest of the info that is used by default on each algo.

Hi doktor, I have a question.
I'm mining using the start-algo-switching.bat to mine on MoneroOcean and I have one specific card that sometimes has some strange behavior. I use OverdriveNTool to set the fan speed at 3000 RPM for each card. I reset the vegas and apply the clock+fan speed once while starting the miner. Sometimes during mining (I don't know if it's during the algo switch or not) I have one card that the fan goes to 700 RPM, making it a lot hotter than the other cards. If I manually close the miner and start it up again, the reset vegas + overdriventool makes the fan run at 3000 RPM again. So I don't want to be so quick to judge that this is a hardware problem.

This happens very randomly. it might be twice a day or once every 4-5 days.

So now the question: how would be the proper way to identify a high temperature for this specific card (or drop in the hashrate, since the Vega throttles and the hashrate gets lower) and to trigger a custom batch file (that in this case would simply restart the computer)? how can I use reboot_script_gpu_watchdog or reboot_script_min_rig_speed but to trigger for one specific card? I don't have one single config.txt file because I'm using algo switch.

Thanks a lot

I have a feeling it is older than 1809.

1803.

i have the same issue. randomly closes at multialgo and work like a charm for weeks at single algo. rigs 8-9 vegas. nothing unusual in logs.

The developer said he hoped this would be fixed in this new version, but today I experienced it again: the miner window closed by itself and there wasn't anything unusual in the logs, just normal mining.

Is the miner crashing or the video driver? Do you get the 'hardware blocked..' system message ?

The miner doesn't crash (the window doesn't close). The message I receive is from watchdog "GPU crash detected, miner will try to restart".

a logical thing to do would be to try out your wow settings without algo switching, so you will know is it related to gpu's not released correctly, driver crash, or it's just the algo.

Agreed. I left the miner mining exclusively cn-wow for the last 5 hours and had zero problems so far. In an algo-switching scenario I'd have already encountered at least 6-7 crashes in the same time frame - it really depends on how many times the algorithm switches. It might be also helpful to say that this crash happens sometimes and right after the algo switch. Sometimes it will switch to cn-wow and mine normally, sometimes it will lead to crashing GPUs and subsequently mining with 10-15% of the hashrate until miner restarts.

I can leave it mining wownero for a longer time, but I'm almost ready to discard this being an overclock issue.

Sometimes when pool requests an algorithm change to cn-wow, I think the miner doesn't release GPUs correctly and it ends up crashing them. The miner reports that one or more GPUs crashed, and it also shows they're hashing with maybe 10-15% of the normal hashrate. After a few minutes the miner restarts because I've set a minimum rig speed. I didn't have this issue before when cn-wow wasn't present, so I think it's related to the algo itself. I was under the impression this algorithm would work with cnv8 clocks/settings.

One issue that I've been getting since earlier versions is that, while mining on a pool with multi-algo support (MO), sometimes the miner will just close without any apparent reason. The command prompt window just closes. When checking the log, nothing abnormal was happening. Sometimes the last line on the log is an algo change, sometimes is submitting a share. Miner just closes. Any idea of what may cause that or what else can I do to test more and provide more feedback?

forget about cn-gpu crap. It is much better on nvidia. And will be easy for fpga/asic if have any volume

I agree and tend to believe in the same thing. I removed CN-GPU from my list.
About the temperatures, what other AMD Vega miners are experiencing? Sometimes I think HBM at 75°C might be too hot, although it doesn't throttle at all.

cn-gpu is core heavy.  maybe you were mining coins that weren't core heavy before?
Check the fan control on this particular one, check positioning of this card.

I'm mining on MoneroOcean, so I was mining whatever they had before there. Never had an issue. HBM temperature never goes above 75°C (normal-v8). You can check this image to see the current temperatures (and maximums). The maximum fan speed is usually when the miner restarts due to algorithm change. I don't know why the fans for all cards go crazy when it does the Vega resetting, but they do.

what suipšly you have?

for GPU algo u must have 1800+W power
try with this card and other 4 card- disabe 1 card and try again

i use only 880/900mv for gpu and mem

I have 2x 1000W so 2000W. I don't think that power is a problem.

I have a MSI Vega 56 (Hynix) and this card is crashing the whole 6x Vega rig (Windows 10) when mining CryptoNight-GPU. It seems like this card is getting strangely hotter than all others when mining this algorithm as well. Usually it's the colder card of the rig.

P7 is at 1408;950
Mem3 is at 890;945
