AMD OpenCL Momentum miner

[Raiden]

Hello,everyone!I have 2 290s and 2 7970s.I found something weird：290@1180/1400  only got 3250Cpm/card(two threads -a 1) and 7970@1050/1500 got  3300cpm/card(two threads -a 1) ,13000cpm total.290 even slower than 7970?I can not accpet it.Please tell me how to tweak it?Thx.

Got Ubuntu installed on my second rig, this time I decided to try out some OC. I used one 290X for this test, clocked at 1150/1400. Only Running -t 0,0, no gains noticed from -a.

My 4 x R9 290's are getting 12270 c/m (collisions / min) and ypool is reporting 1360 s/h (shares / hour).
I think Hukkei meant to say 1800+ s/h (shares / hour), not 1800 s/m (shares / min). You might be missing
the hour & minutes conversion since your 24 s/m is really 1440 s/h.

:-)

Just wanna check if my values are okay or not:

I got actually 2 R9 290, producing about 6400 cpm, but only ~24 spm. Is this okay? I'm just asking because Hukkel said 16900 cpm will make about 1800 spm... that would make 600+ spm for my 6400 cpm (if I wasn't to sleepy to calcuate that :D):/

if you have a 280 gpu with no monitor connected, you can run -t 0,0 (2 threads).
with monitor connected you better run -t 0 (1 threads)
So i have to run -t 0,0,1 (3 threads) because at device 1 there is my monitor....

-t 0,0,1 gives me 6200 cpm with 2x 280x

I'm using CAD software, and I get some lag, I need to decrease the intensity.

Note: I'm using 1x280x - Sapphire Dual-X, and using 2 threads makes cpm drop to around 1400. Seems that there are different results for 280x

Can you implement something similar to the Intensity in cgminer?

I would like to work and keep mining using the same GPU.


Thank you very much for your hard work!

Wow! That's VERY impressive indeed! I have 4 x MSI R9 290 Gaming cards running
Win8.1x64 with tweaked settings from AfterBurner and I'm only getting ~12300 c/m
with the latest software from NaN. I'm still tackling the 2 thread thing myself and
currently run the -t 0,0,1,1,2,2,3,3 which doesn't get me much more c/m but severely
increases my CPU usage for some reason. I'm assuming you are running Windows as
well since you mentioned "run in their own window" or are you running Linux and just
have multiple terminals open? Much thanks for this info!

Listen to this. I have 3 280X.

1 Gigabyte 280X windforce OC
2 Sapphire 280X regular model.

The -t 0,0,1,1,2,2 -a 1 scrypt did not work well enough for my setup. I reached 8400 CPM with it.
I think I found out why.

The sapphires run now each in their own window @ 3496 & 3457 CPM each using 2 threads and -a 1 algorith

The Gigabyte does not like that. It stays around the 1.400 cpm mark. I do use it for the monitor but ok.
So i delete the -a 1 scrypt; 1600 cpm. MEH
So I take it back to basics: 1 thread and no algorith choice.
Now it runs happily at 2.600 cpm.

ODD

So one 280X is not the other 280X and for PTS mining I would RIGHT NOW recommend the Sapphire regular version of the 280X. BUT just because of my own experience. I like the Gigabytes but I can't find the optimal configuration yet.

I am happily chugging away at 9700 cpm in total now with these 3 cards
And @ 1150 shares per hour.

Not too shabby. With the right cards a full rig of 280Xs (5 pieces) would ramp up to 16.500 cpm and 1.800+ spm.

You should get in touch with cbuchner1, maybe you can come up with an improved mmc/pts miner.

So finally... no CUDA miner realized?  ::)

I'm working on Nvidia support but I do not have a fully functional version yet.

Thanks for the reply NaN, could you give to us a little idea about the performances?
;) Regards

That update, with my R9 290x with 2.1 i have 2k cpm and im happy, with this update 3k Oo, Thank you so much. Please add nvidia :D i have 3 nvidia :(.

Ps : with r9 290X i have the beter result without -a, 3150 cpm.

We are all expecting your outcomes and will appreciate for everything you will be done for nvidia. Hope we will have similar performance as AMD.

Does anyone have a link to a good ubuntu install with directions for a bootable usb flash drive, so I may try booting my system under ubuntu to try the other version out... so far I have failed and found malware or installs that did not seem to jive with the directions they put out there... I mean there has to be a simple image out there that'll fit on a 16GB flash drive just waiting to be written...

(I should say a current ubuntu install, I've found many old ones but I'm trying to find ones that will work out of the bat for a complete linux novice with R9 drivers)

Heh, thank you to the person who PM'd me quickly with the link below... you can download the pen drive program, as well as the 13.10 iso quickly... I guess they were right, I really did over think it by searching out specific things instead of just going to ubuntu directly.
