R9 270 - Tweaking - \[BAMT SMOS\]

[quote name=“prensel” post=“50386” timestamp=“1389077891”]
Did you run [code]aticonfig --adapter=all --initial -f [/code]again ?
what does [code]cgminer -n[/code] say
[/quote]

so the first line i put into terminal pumped out this

[quote]unitialised file found, configuring.
using /etc/x11/xorg.conf
and also saved a backup but i havent bothered typing out this line.[/quote]

cgminer -n
file not found.

do i need to navigate to a directory other than home?

I also get this when starting and stoping the miners. Also when restarting the miner.

cp: target “backup.conf” is not a directory.

Haven’t noticed it till i put in the second card.

ive also done the bit with the conf where you need to put cgminer: 1 in each spot for the gpu’s and yeah. i think i need to get a fresh defult setup and start from scratch. i thought it was just gonna work when i added in the new bits in the conf file.

But yeah. im definitely hashing. my pool is giving me stats… I can hear/see the gpu fans spin up. [i]I’m drawing 240 watts now.[/i]

I’m happy that im hashing but i would really like to see whats going on rather than relying on the pools stats.

Is this to be run from terminal or does the aticonfig line go in my bamt.conf?

It’s registering both of my gpu’s on 0 and 1. but yeah. when i start the miner nothing detects the hashes… just my pool… all though, i think i made a change somewhere and now that’s not even working… ive turned it all off for a bit but ill check out those 2 lines soon and let you know.

Yes run it from the command line like [code]sudo aticonfig --adapter=all --initial -f[/code]
Also run the cgminer command from the command line but you might find it first in its directory somewhere and then [code]sudo ./cgminer -n[/code]

And don’t forget to reboot after the aticonfig

Ok it spat out some information. A bunch of things arent happy but it see’s my 2 gpu’s.

Iceweasil is having issues posting on the forum here so i can’t copy n paste it all over. what am I looking for?

OK so I rewrote my bamt smos distro onto a new usb.

Booted from that.

Chucked in my worker info on the cgminer.conf
Fixed up the bamt.conf to use cgminer and gpu’s 0 and 1.

Ran this in terminal [quote]sudo aticonfig --adapter=all --initial -f[/quote]

Rebooted. Nothing seemingly.

Ran this in terminal after navigating to the cgminer directory. [quote]sudo ./cgminer -n[/quote]

Rebooted again and jumped into the bios and set the on board hdmi to be used. Then the monitor wasn’t picking up anything but with final reboot and having the monitor hooked into gpu 0’s hdmi, bang!

Everything is working now! LXTerminal is reporting both gpu’s, I see green text and temps and speeds and its all sweet.

GPU 0 is cooking hot at 78 celsius and gpu 1 is at about 69 celsius.

I don’t have my tweaks running so I’m at 430Khash/s for both cards. Total speed. 860 Khash/s drawing 390 watts.

+1 rep prensel.

Thank you for your help. It was muchly appreciated! Next step… adding the tweaks :D

That’s where the fun starts :-)

Wow, I missed out on this (doing support) I haven’t been looking at mining. [BAMT SMOS]

Has it been announced? Chrisj is looking for stuff for News, this should be in!..

Wow… Brilliant.

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.

Small update.

Note to self… need risers…

GPU0 temp: 90c
GPU1 temp: 69c

Total hashrate: 960Khash/s
Total Watts: 460 watts

These temps are getting dangerously high… This is with cold air been pushed over em as well.

A riser is required.

If I left the speeds un-tweaked, then maybe I wouldn’t worry so much. But 90c is just a little to close to 100c…

prensel

That 90c is too high.
Drop some engine or memory ticks to be safe.
You can also try to lower the intensity with 1 or 2

Dropped:
intensity -> 18
engine -> 1100
memclock -> 1400

Concurrency is still 16000

GPU0 temp: 78c
GPU1 temp: 67c

Total hashrate: 760Khash/s
Total Watts: 395 watts

So I’ve lost about 100Khash/s from each card but I feel confident they won’t die/fry overnight.

I’ll put my tweaks back up to my “max settings” once I get a riser to give them some breathing room.

Thanks again prensel!

[i]edit[/i]

I turned off the aircon and GPU0 shot up to 84c instantly…

I’ve shut down the whole miner for tonight. They need risers.

If they were in there own machine each, then the heat is fine. But together, it’s too much without rising them away from each other.

Tomorrow, I might just run it as a 1 card system until I get said riser.

You may have mentioned this already, but are you running linux via thumb drive?

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.

digitaldaze

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.

wrapper

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.

[center]Proof
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

mirrax

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 ???
