R9 270 - Tweaking - \[BAMT SMOS\]
-
nice your answer fits my question down to the dot. So you pretty much just have like 2 tabs open in the guiminer one for the 7850 and one for the r9 270x? Also what power supply do you use to keep them both nice and stable if I may ask and are you also on windows 7?
-
Just to chime back in here…
After more fiddling I’ve managed to get my hashes up to 425KH/s stable with no HW error @ 70C
I had heard that the R9 cards couldn’t handle intensity above 13 so hadn’t raised it above that. I decided to take the plunge last night and after some testing settled on 19.
I’ve still a way to go before I get where I want (450-480) but things are improving.
I’m in the process of writing BAMT SMOS to a USB drive and will report back once I have it up and running…
For those who are interested here’s my .conf

}If any one has any suggested changes I’d love to hear them ;D

Me again.
BAMT SMOS installed and is giving me about another 10-15KH/s over Windows 7 x64 - every little helps!
Love the browser monitoring!
Calem, have you got any fail safes in place for crashing etc? On my Windows miner I had batch files to quit all programs, reboot and restart mining once a day just in case of any issues. I never actually had any issues but it was just peace of mind for me.
-
I don’t have any fail safes… I was hoping these lines in the conf file was what was keeping me from going “whoomfka!”
[quote]“temp-cutoff” : “85”,
“temp-overheat” : “80”,
“temp-target” : “72”,[/quote]Not sure if I’m using those exact numbers, but I haven’t made any changes to them on my SMOS install.
Also, I think there’s a way to set up SMOS so it auto starts mining when it powers up. Just not sure how to do it. Haven’t looked into it.
Tonight, I’ll have a look through your conf and see if I can suggest any tweaks.

[/quote]Thanks bud!
EDIT: I’m a perpetual fiddler! Got it up to 480KH/s buy changing to thread concurrency to 16000. Weirdly if I use the same settings in Windows I get HW errors all over the shop! At the moment, using BAMT I have 0.00% invalid shares. I presume this mean I’m not getting hardware errors as I can’t see any HW error reporting in the browser monitering tool?

[/quote]Oh excellent!
BAMT SMOS FTW
Nice going ahy!.

[/quote]After some research it would appear SMOS starts mining automatically when it starts.

I now have the amount of power the whole rig draws.
230 Watts
480Khash/s
75°c. -
Thats low wattage! Well done!

[/quote]It is? Well that’s good. I’m still yet to learn about/try out under volting so hopefully I’ll get this running even more efficiently. Hopefully I’ll pick up my second 270 tomorrow, so I’ll see how the watts go from there.
-
I’ve got my second card in now… Catch is, the pool tells me I’m hashing between 950 and 1050. But cgminer/smos can’t see it. It’s simply not registering in the terminal. its not giving me any indication I’m mining.
I know I am hashing though. The cards spun up and my pool is reporting im accepting shares. so this is all a bit strange. I’m thinking of trying a different usb distro…
oh. I’m still using about 235 watts as well.
-
Did you run [code]aticonfig --adapter=all --initial -f [/code]again ?
what does [code]cgminer -n[/code] say -
I’ll have a look.
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.
thank you for your help ahy

[/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.

[/quote]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?

[/quote]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

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.
