Next time it will be welcome if you refer who made the change of the motd … lot more mods I have, but if this is the politic of HiveOS I think is better to have it internal…
and motd should be configured right…

Next time write your own motd and then mod it as you like

Re: AMD Mem Tweak XL - Read/modify timings/pp/straps on the fly

NOTHING CONCLUSIVE--

I tried reading the several threads that I found after searching earlier posts in this thread concerning user-modded 5700 series AMD graphics cards.  The user claiming to be attempting BIOS mods and uploading them with ATIflash has poor English or is deliberately using LOLcat-speak.  Nothing posted is legible enough to make sense.

Other long-time gurus explained that that the latest AMD cards have encrypted and signed BIOS. The Navi series won't accept a BIOS flash the way Polaris and earlier cards will.

If you can point me to a legible post or review explaining how to alter a Navi BIOS and flash it, please do.      
--scryptr

Of course they can...even before 5600, you could flash 5700 with 5700XT bios...but all of those are AMD-made, already signed
bios-es. Flashing is not a problem, but signing

Hi, PhoenixMiner!
Merry Christmas and Happy new year!  Cheesy

It seems that Nvidia kernel optimizations for lower power consumption no longer work for last DAG epochs so it is needed to increase core clock or PL again and again to get the same hashrate.
Please take a look if it can be done again.
btw, 440 series nvidia drivers are greatly optimized in terms of irq/queue performance, producing twice less LA on heavy gpu usage. and new cuda 10.2 also.

Next problem - when mining is resumed after reaching tstop/tstart gpu quite often get stuck after few such cycles. Can resuming be done more smooth from low intensity and step by step increasing to target?
Also intensity can be reduced in advance when getting close to tstop temp.

And what about gt auto-tuning not from 0, but from defined gt values? it will take much less time and be more accurate. so there will be no need to set exact values every time oveclocking is changed for one of gpus.
it can be a problem as auto-tuning runs after each stop/resume cycle and can take longer than reaching tstop temp again)


Thanks in advance!

tested 1.88 version on GRIN31
13xP1070Ti: reported - 13.2, avg on sparkpool - 12.5 (~3% stales). difference is about 5% = devfee + stales
13xP104 8g: reported - 11.9, avg on sparkpool - 10.6 (~4% stales). difference is about 11%!!

second thing that can be easily fixed - auto-tuning is quite slow and it is running after gpu temp reaching its limit. every time!
there is no need for this. just use gt values found during startup.
   It is deliberately "slow" (it takes 3-5 minutes on average) in order to get repeatable and reliable results. If the auto-tuning is significantly faster, we will be taking less measurements and as a result the "best" GT found may not be optimal. To avoid the problem you are running into, you can run auto-tune again after the temperatures has stabilized. In order to do that, you need to press the 'z' in the miner console window.


no, i am not complaining about its slowness.
the problem is that if gt is not set, auto-tune runs every time gpu starts mining after reaching temp limit.
so, instead of start running at 33MH with already found gt value, gpu starts at 26MH and when it reaches 33 after few minutes, it can reach temp limit again and stop mining.
yes, that is not normal in long term usage, but when it is too hot you have no so many choices.

btw, what do think about starting auto-tuning not from 0 but from user-defined value?
so if most of gpus have the same +/- 1 gt value, you can set, for example, -gt 15, and auto-tuning will try higher and lower values for best performance, and it will take much less time to complete.

PhoenixMiner

Please fix support for newer drivers on linux - 19.10, 19.20.
currently miner uses -clnew 0 regardless of clkernel setting.
probably all these kernels can work if there was no check for driver version.

second thing that can be easily fixed - auto-tuning is quite slow and it is running after gpu temp reaching its limit. every time!
there is no need for this. just use gt values found during startup.

Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v14.6 (Windows/Linux)

It seems drivers are unstable at this number of cards.
If 11.9 works fine you can try to add "-eres 2" option, miner will use old-style DAG generation (since v12 it tries to reduce GPU memory used for DAG in most cases, non-zero "-eres" option value disables it).

yes! -eres 2 make it work! only LA is relatively high.  but anyway thanks for advise!!!

btw, in first post it is written that it is default option:
Quote
-eres   this setting is related to Ethereum mining stability. Every next Ethereum epoch requires a bit more GPU memory, miner can crash during reallocating GPU buffer for new DAG.
   To avoid it, miner reserves a bit larger GPU buffer at startup, so it can process several epochs without buffer reallocation.
   This setting defines how many epochs miner must foresee when it reserves GPU buffer, i.e. how many epochs will be processed without buffer reallocation. Default value is 2.

Thanks, I had a good laugh here Smiley
Unfortunately, I don't have 13 p104 cards to test it. So 12 cards work fine and 13 fail, right? There is no difference for miner if you use 12 or 13 cards so it must be something else, try "-gser 2" option to see if it helps.

hmm, yes. 12 cards are working. you definitely do not like this number)
and 13 with with -gser 2 option, too. but very slow startup.
with -gser 1 does not. and I found in syslog this
Code:
[27382.925779] Out of memory: Kill process 10880 (ethdcrminer64) score 684 or sacrifice child
[27382.925822] Killed process 10880 (ethdcrminer64) total-vm:321404352kB, anon-rss:1346268kB, file-rss:1308172kB, shmem-rss:133120kB

sorry, forgot to take a look there earlier
hope this help to trace the problem
v11.9 also works without -gser.

TBH Beam (and equihash in general) is a waste of time and money on AMD anyways. Lolminer should focus on delivering a non-shite cuckoo miner since he clearly has a better understanding of opencl than most, and (I propose) a 5% dev fee for it; that's a miner I would use.

Can you confirm that you are seeing v3 kernels loading in the log file? (it should be in the first few pages of the log file, immediately before the card starts to actually mine). We have tested on GTX1080, which should be the same as P104 but perhaps the better memory timings in P104 cause the difference in behavior.

yes, there was v3 kernel in log file after creating DAG. P104 is more likely 1070 with fast memory.
I found that decreasing power limit reduces hasrate on 0,038MH/1W. but I do not tested yet if it works only with v3 kernels.

It's not even close to efficient if that's the question...  Even @ 90MH/s you're burning too much power.  80-85 is a good spot, I'm doing 82 @ 215w.

that's great!
