R9 270 - Tweaking - \[BAMT SMOS\]

[quote name=“digitaldaze” post=“50491” timestamp=“1389112280”]
You may have mentioned this already, but are you running linux via thumb drive?
[/quote]

Yeppers.

no hard drive, no dvd/cd drive. I just boot BAMT SMOS strait from USB. The GPU drivers etc are all ready on there so you just need to configure your .conf files and away you go.

Got my R9 270 going.

I used catalyst to take gpu clock to 1050 and Memory Clock to 1500. With those changes, guiminer went from 411 khash/s to 443 khash/s. Holding steady at 66 degrees C.

Somehow I can’t get the cgminer config file to be loaded. Gives me a JSON error and that it can’t be loaded. :(

I’m still messing with it.

Hey Calem,

thanks for telling me about the R9 270. I bought one new, for the same price as a S/H HD6970.

We couldn’t get the USB BAMT working, but we’ve installed the usual 12.04 Kubuntu / cgminer , and it is running really cool at 250 KHash.

We’ve just set up 2 virtually the same Core2Duo Towers, (HD68970 / R9 270) both running at 250 HKash, so we’ll try and compare the watts.

I don’t really go for max hash (after blowing up 2 power supplies) , just cheap builds.

Hey that’s kewl =^-^= They’re a nice cheap card considering how far you can push em. I think from here on in, I will only buy and tweak R9’s that have no “X”

Did you try BAMT SMOS?

I couldn’t get the normal BAMT working. I went with SMOS because it all ready has the drivers in it for the R9 series of cards.

Oh ok.

Have you tried pushing intensity to 19, concurrency to 16000, etc? Or can those other changes only be done in the cgminer.conf file?

I really must of fluke this.

When I get my riser my little rig will kick some serious butt.

Also sorry it’s so dark… The camera I recently bought is designed for outdoor use :(

Yes, those numbers are with intensity set to 19 and concurrency to 16000 I can’t set much else other than the GPU Clock and Memory clock I already mentioned. Rig has crashed twice though, since yesterday, not sure why. My max with this card is ~440, my rig is currently pulling 557 khash/s with the CPU mining I’m also doing.

Still gonna try and work the cgminer conf file.

If you want, if i have time tomoz, depending on your time zone… Because your also using a strait 270, I can skype you or something and ill try help you work through it.

Using a BAMT SMOS usb boot is probably the easiest way to go. That worked for me no problems. I can help you set up like ive done mine. I’m really interested in getting people to beat my speeds so I can copy them :D

I just converted from win7 to BAMT, so far I like it, especialy remote desktop.

Now need to figure out how to configure 2 gpus :)
(R9 270 + 7790)

So far I modified config file with 7790 setting but it seems R9 picked those setting and is running 63Â°C 420kH/s now, while 7790 don’t mine at all ???

OK, it is working, hash rates are just as expected, but gpu0 have some problems:

I’m using win7 right now, shall try bamt smos soon, as max i can get now is 440Kh/s per card.

I’m fiddling with two very same gigabyte r9 270 cards (and 2 more coming soon) and i’m curious about power efficiency and cooling at that impressive 960Kh/s

I’m using 600watt psu rated at 82% and it draws (measured from wall)
idle ~120watt
at 2x440Kh/s ( engine 1050, memory 1500 intensity 18) draws 430+ watts

But there’s the thing, at 949engine and 1400memory vddc can be lowered to 1.163v which gives 2x400Kh/s and power consumption of 370+watt and no overheating w/o risers.

SMOS is “secretely” mining 15minutes a day for developer, taking 1% of your daily mining power.

[url=http://www.smos-linux.org/donate/]http://www.smos-linux.org/donate/[/url]

To be honest I am ok with this as far as he keep the developement.
What I don’t like is that this information is not obvious when you start with smos…

EDIT: be carefull downloading any unofficial smos, % should be much higher!!

I don’t think anyone should be ok with their OS being trojaned with a secret CPU/GPU-cycle-stealing revenue stream by the developer.

You should demand your OS is trojan horse free, and donating should be an opt-in experience, not an opt-out one.

Apparently it’s easy enough to write it out. It is also stated on the site that it mines for that 15min period.

With that said, it should be clarified a lot more right next to the download link. Also it should be easy to remove it, the file is hidden.

To be honest, I didn’t know any of this when I first started using SMOS. When I found out, I posted it in this thread as a comment strait away.

[quote author=Calem link=topic=6473.msg50423#msg50423 date=1389092555]
Thought i would mention… BAMT SMOS will mine litecoin for 15 mins at 3am local time for the dev of the distro.

The line of code can be removed out, but its a standard donation thing that comes bundled in… many are claiming its a scam and that its not mentioned but the guy who did this has clearly posted on the main site that his setup will auto mine ltc for 15mins at 3am local time. but If it impacts on me too much i might remove it. i might not. its worth it considering the speeds it gets for me… that and the drivers and everything for R9 cards are all ready packaged in.
[/quote]

But yeah, as long as the guy keeps on providing support…

With that said, when I have time, I might remove it. Especially if I start hashing greater than 1Mhash/s

It seems, this “mining” kicks me out of my pool, but then after finished (if) didn’t restore original mining.
Screw this, I will try Ubuntu.

Damm, both Ubuntu and Xubuntu wasted so much of my time, [b]ubuntu the shittiest os EVER[/b].
I followed this guide:

but every step failed.

I’m really caught up tonight, but over the next few days I’ll try answer your questions in depth.

For the time been though, I can answer no.3

3. How are you measuring your power draw for each card/your system?
[/quote]

Bought a watt measuring thingy from work (Jaycar electronics). Plug my miner into it, and it goes into the power point. Tells me the wattage for the whole rig.

I have 3 more 270’s and 3 7950’s on the way… eventually I am looking for a 3x270+3x7950 and hopefully get like 3.5 Mh. Might put the other two 270’s into my main rig instead, but its a Win 7 so might get like 800kh or less maybe… not sure if its worth it, but I leave that PC on like 24/7 360 days a year anyways so… might as well? I might have to do some calcs.
[/quote]

win7 is just a few Kh/s behind at those seetings, check it out, 468Kh/s on gpu0 at e1125 mem1500:

Just wondering if you guys are getting Hardware Errors? I found that I am getting some… tweaking causes my khash rate to go down, but more accepts.

EDIT: Nevermind, I figured out my problem.

To be honest, I haven’t run my miner in a bout a fortnight. It’s been getting very hot here and I’m in an apartment. So it’s just to warm to run it now. Once I get into the new place, I’ll have it seperated enough that I can start running it and doing some more experiments.

*13.10
going to try 12.10 now

Xubuntu 12.10 1,5hour from instalation to succesfull mining!
I strongly recommend, much better then Bamt ;)

That, i have found is the most frustrating part of mining…the misinformation or bad information you find. Following a link and then every step fails, for seemingly no reason. I am having good success with the BAMT SMOS at the moment. I like the reliability of the software over win 7, which will throw in updates even when set not to. I have a question about BAMT SMOS…

1. I have multiple rigs and want to set up a farm using BAMT. Have done all of reading and research, but can’t quite seem to get it. Has anyone else used it with a farm? if so, any help with getting that set up correctly would be much appreciated. I am using the CG Remote and love it, but it is windows based.
