Topic: AMD R9 290X? - page 5. (Read 108829 times)

You posted a picture of DVI which have ability to be used with DVI to VGA converter. So card on picture HAVE analog output, 290 doesn't have it:

I had problems with the Sapphire R9 290 cards. Had 6 of them and similar problems as posted earlier. I did manage to get them to hash at 810Kh/s but very unstable. I ended up sending them back for R9 280x vapour-x cards. Which seem to be clones of the 7970 dual-x. They work flawlessly at 740Kh/s.

Sorry, but that is wrong. You can resistor mod a digital DVI connection, doesn't even take more than one resistor. 

290 doesn't have analog out so no resistor mod, if you want to work without monitor you need enabled GPU part of APU on motherboard.

My problem was completely because I didn't have a monitor hooked to the video cards.  As soon as I hooked a monitor up everything started working.

I've played with the numbers a bunch and haven't had any luck.  I'm trying random drivers and windows update at the moment.  I wasn't sure if the resistor mod worked on the DVI-D cards.  I'll poke around and see what I've got.  Not sure I have any that low sitting around.  Thanks for the tips!  I'll report back.

I launch from a bat file, looking something like this. Not sure if it's necessary or not.

-setx GPU_USE....
-setx GPU_MAX...
cgminer.exe --scrypt

You can't (usually) run a TC higher than 8192 when using -g 2, on a 280x. Some will do -g2 tc 11200, but not all. From what I've seen the 290's like single threads and high TC.

Try using a TC that is a multiple of your shader count, Not sure how I missed that before. 290's have 2560 shaders, generally you can only run 4x, maybe 5x, shader count with -g 2. Somewhere closer to 10x for -g 1.

No idea what all this ADL stuff is, but if CGminer starts the cards I wouldn't worry about it. I would disable the integrated graphics after installing Teamviewer, then just use little 75ohm resistors to dummy the 290's DVI-D ports. When you turn the PC on it will activate the AMD drivers as the main display, and when you teamview in it won't switch to the goofy RDC video driver that kills AMD's driver. Might be worth a shot, maybe?

Under Windows I typed:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

It said saved after each of those commands.  That's something I only have to do once...right?

I didn't export under Linux because I couldn't control clock speed or monitor temperatures so I just shut it down.  It's been very frustrating.

You are using the sex-x (windows) or export (linux) commands right? gpu use sync objects 1 and gpu max alloc percent 100? Linux apparently needs an "export display=:0" command as well.

Omitting those will limit the ram CGminer can use, and thus the highest TC will also be limited.

My best guess...

I've been stuck for two days trying to get my 290's to hash.  I spent a day with Windows and a day with Linux.  So far it hasn't been very much fun.  In Windows 8 I can't seem to get the ADL monitoring to work.  It always tells me there are fewer instances of opencl than ADL.  Nothing I try will let me change clock speeds.  GPU-Z shows the card working fine, but Afterburner comes up with all blanks and anything I pass to cgminer through the command line regarding clock speeds gets ignored.  Here is the thing that really has me stumped.  No matter what I try to change if I move my thread concurrency above 8192 cgminer gives me an error about having to reduce TC or raise my lookup gap.  With the LG set at 2 I can't go above 8192.  If I set it higher then the TC can go higher, but the hash rate dies.  I have one 290 that hashes about 475kh/s for a few minutes and then drops to about 90-100kh/s.  If I raise the intensity above 13 it puts out nothing but errors.  If I just start cgminer with the default settings the card hashes about 20kh/s.

I have two other cards in a newer motherboard that are doing the same exact thing.  Windows 8 ADL doesn't work and they each mine about 490kh/s because I can't change the clocks or raise the TC above 8192.

I just spent the last 17 hours fooling around with Ubuntu.  When I install the drivers everything looks great, but on reboot the screen just goes black like it is ignoring the integrated graphics and defaulting to the 290's.  This wouldn't be a problem, but I don't have a monitor with a DVI-D connection.  I've tried to use xrdp to remote in like I do on my Raspberry Pi, but it just gives me a fuzzy black/white screen with an X for a cursor like it is some kind of "green screen" overlay.  I can't do anything or see anything other than the X cursor.  I can SSH into the system and the cards show up as active with an xglr driver assigned to them, but since I can't startx in putty I can't get it to mine.  I briefly got two cards mining by using the old 3.3.1 cgminer from the repository, but they would each only do about 320kh/s.  It was the same story as Windows.  ADL wasn't working and I can't raise the intensity above 13 or the thread concurrency above 8192.

Can anyone throw me a few tips?  I'm going nuts over here.  I never had any problems with my 7970's.  heh..

What are your cgminer arguments?

FYI my solution was to install Windows Haven't had problems with any other card in Linux but for me the 290's a no go, latest drivers for everything but after hours and hours I couldn't get the cards detected by cgminer. All working well in Windows.

I have tested one R9-290 for a short time
voltage -70mV in afterburner, 1.06V reported in gpu-z
fan speed fixed at 65%(really loud), temp goes up to 84C in not so warm room
default clocks 947/1250 and result is ~820kh/s

Didn't have time to find power tester and to try overclock, maybe with next card...

where are the settings for the guy running 270w at 900kh/s? Was looking through the thread and couldn't find it 

I had to boot X and run cgminer inside of x for it to detect the card. I tried various methods I found online to mine from the prompt without x with no success.

I picked up 2 cards today. Put one in my windows machine the other in my linux machine. I didn't have enough PSU power to put them both in the same machine.

The one in the linux machine is getting around 800Kh/s without doing any tweaking to it, but the one on the windows machine is only getting 500Kh/s. Driver issues? Anyone else experiencing slower than normal operation in windows than linux? Same config on both machines.

The linux box seems to hard lock anytime cgminer exits though. Causes the entire system to hard crash. More driver issues?

The GPU is not worth it then.

Are you trying to run headless? Does 'sudo --aticonfig adapter=all --odgt' mention anything about hardware monitoring enabled?

You are using export DISPLAY=:0 right? Seems like your cards are detected, just not active. I still have not been able to SSH into my Xubuntu rig running 13.11 either...

Anyone?
