lolMiner 1.53: Dual mining Eth+Kaspa and more efficient AMD kernels

[Metroid]

Here is my active testing thread on the 6800 non-xt

https://twitter.com/BitsBeTrippin/status/1330884361475026950

Bottom line initial testing 81MH/s on ETH @ 170w

Now time to tweak powerplay tables and see how low we can get the power down to.

Not bad, $579 / 81 = 7.1 usd per 1 mhs, 3080 is $700 / 98 = 7.1, 3080 still a little better due to density but the 6800 uses a lot less power, so that is a draw.

Lolliedieb, What about this:

Another question:
RX 580-8 rig. On 1st card of rig when monitor connected and trying to look video on youtube or play any videofile (even in bad quality f.e. 320p) video playback goes with freezes. On all other miners (Claymore, TR, PM) video plays without problems during eth mining.

I have this same issue.

My 6800XT by default treats the GPU as one, so my result is abysmal in comparison. I am still not sure if I fully understand this result.

81Mhs but it shows 2 gpus (0 and 1) so is it only 40mhs each....

Somebody got more info on what is going on there?

Ok..i see it is treating it (the miner sft) as two separate gpus with 8gb each....makes more sense

Here is a latest video on it. YouTube https://youtu.be/xd6qTNvWsKg

Note: My next steps today are the following

1) Run continuous for 2 hours against a pool and validate shares/hashrate

2) Test same config using 1x to 16x riser to see if SAM works same on riser

3) Test Power Usage at these rates, see about powerplay tweaking on what we can get out of it.

Is this speculation that Shared Access Memory is causing two logical devices appear? Have you toggled this on and off to confirm the scenario?

I did previous video with it turned off, I enabled it today and tested and got those results.

I am not sure why as a consequence the smart access memory would create a second logical GPU. Very odd. Neat in your case but seems like a strange consequence.

It's definitely a bug. I disabled 4G Decoding, BAR in the BIOS, rebooted, DDU'd the drivers, reinstalled drivers, tested without Smart Access Memory, then tested again with it back on and now back to 1 GPU still.

Looking to see if something else I was doing caused it to pop two instances of the miner. The limited time I was running, it was in fact getting 80mh at the pool and had both compute 0 and compute 1 under load in the GPU monitor; now I just get compute 0 with the single thread.

Bottom line, bug or not, there is headroom here for dev to enable that second thread officially.

Never thought that is possible to miner recognize 2 GPUs like this, it makes no sense 

But now, with miner recognizing only one GPU, what's the hasrate? 62 to 65mhs as in your first video?

And maybe you found a bug and devs could use this approach to modify how miner works, at least with new AMDs cards

Imagine this working with 3080 , 5GB is just right

I've got no positive results on RX 470 4GB rig even I tried all different miners including the new lol miner 1.16.
I haven't change the old blockchain driver and the result is still poor, max 10 Mh/s for the whole rig.
Now I'm waiting for ETC Thanos fork at the end of November.

But this is normal... the DAG file is too big that it cannot be all loaded in mem... you have been using the Zombie mode that allow you to mine but with lot less Mhs... at least you were able with this miner. If you want the best improvements mine ETH until the fork of ETC. That will give you better performance until the change.  It is only a recommendation...

It might be, because my miner has no pauses between kernel calls ... it has two threads to keep the card busy ... Will need to think about this.

Can you share more info e.g. driver and operation system? I am running my 580 4G with still 15 mh/s on ETC epoch 388 in Linux with 20.40 drivers.



Wrt this 6800 stuff: it is indeed strange using the same card 2x. Why this works and if we can replicate this to get the speedup on other systems: not yet sure. Still awaiting an own 6800 for tests, the card to test the miner was a remote one where a friend allowed me to check it out - and there it was only shown as one card.

[jgonzi]

Is there any new about the 6800 x 2 GPU?...

With the limit of bandwith that numbers doesn't seem normal... let's see

i am not able to mine etc+zil wit lolminer someone can helps? thanks

[abarth23]

Which are the best drivers to use with lolminer 1.16 for rx570 4gb?

[jgonzi]

One of the best drivers now is 20.30, the 20.40 is having some problems on som Linux versions.

For mining in Windows, one of the best is 20.4.2.

[abarth23]

thank you so much for your help

[Lolliedieb]

Can you give some details about the problem? e.g. cards, driver, error messages - the more details we have the quicker we get it going

[biblioteczny]

What could be the reason for this message?
"GPU 1: Allocation of DAG failed with error: Memory object allocation failure GPU 1: will be stopped."

I tried to use lolMiner 1.15 and 1.16 - same error.
GPU 1 is a RX 5700 XT 8GB from PowerColor.
