R9 270 - Tweaking - \[BAMT SMOS\]
-
hey since we talking about the r9 270x card I was wondering if it is possible to run 2 different cards. I am running right now Sapphire HD 7850 2gb on windows 7 64 bit. It has 750 or 800 watt ultra power supply on ASUS M2N-SLI mother board im pretty sure it has 2 PCI e spots. I just want to make sure I can run them both " current sapphire card with r9 270x card " with no problems if not no biggie friend is actually going to military so he just giving me the card before he leaves.

[/quote]I believe you can. Don’t quote me on it though. I’ve seen rigs with 2 diff cards in em, so I’m assuming it’s ok.

I’m running a 270x with a 7850, it works just use 2 different instances of cgminer
-
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
“intensity” : “19”,
“vectors” : “1”,
“worksize” : “256”,
“kernel” : “scrypt”,
“lookup-gap” : “2”,

}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?
