I have a Sapphire 7990 (Tahiti) and I am having some trouble getting it hashing just right.

I have win7/cgminer 3.1.1/ catalyst 13.4

I have searched and read as much as I could find on this card and nothing seems to work for me.  Right now I am hashing at 1.1MH/s scrypt with core 1040 mem 1625 & i=16.  I have it inside an azza solano case with one extra fan for a total of 3x 140mm intake fans covering the front panel, 1x 120mm fan exhaust on rear, 1x 230mm exhaust on top, and one 230mm side window fan that I flipped to exhaust.  I set the top exhaust to low to maintain positive pressure in my case and flipped the window fan around to pull out extra hot air that the card puts out into the case faster, since it is right at the card it pulls a lot more heat out this way.  I have ran it with the case open and have no difference so I think my fan setup is good.

My problem is that the temps are getting much higher than I would like.  I run my miner and temps are up into the low 90's on gpu0 within 15-20 minutes.  GPU1 gets hot too but usually stays in low 80's.  I have seen reports of others with these cards hashing at around 80 and lower.  Also seen higher hashrates posted.  I know undervolting can probably solve the heat issue and maybe let me hash faster, but I can't seem to change the voltage.

I have read what I can find about these and I have already edited my registry to disable ulps (so I can change the voltage) and tried disabling it with trixx and AB with no luck.  Others seem to be having luck just editing the registry but cgminer still shows my card(s) running at 1.2v.  Is there anyone with experience on this card that can tell me how to set my voltage lower and get my temps down?

nevermind  :D

among the solutions out there (customize lots of cfg files in msi, edit registry, use this version, that version, uninstall catalyst so it won't overrride voltage settings with AB, use this script to disable ulps, etc....) was the only one that worked for me after all.

simple as put atipdlxx.dll into the AB folder  ::)  cgminer still reads it as stock voltage, but it's running cooler and faster, so until I dig up the kill-a-watt I'm gonna assume it worked  ;)

now hashing scrypt and for those having trouble with the 7990 I get avg. 1.325mh/s with core 1050 mem 1675 voltage 1.1 thread conc 24000 i 20 shaders 2048 worksize 256 vectors 1 g 2

has been up and stable for over 30 minutes, so just gonna watch and keep my fingers crossed at this point....  temps are holding steady at low 80s/mid 70s.  would be nice to have them both at 75 but I will take what I can get  ;D

did you buy the card as a gamer, maybe for work? or did you buy it for mining?

Both as a gamer and for mining.  I have a open air rig full of 7950s, but I wanted to build a nice gaming rig that could be mining most of the time when I'm not playing.  Since it is a gaming machine it had to be semi nice, be able to stay closed, etc.  My thinking was that since it is 2 cards on one physical slot, it's the only way I can make a 4 card system fit nicely into a case.   :P

It was a huge pain in the ass to set up compared to my 7950s but I'm pretty happy with it now.  Just need a second one ;D

had the same dilemma opted for 7950 still since it seems i get high average hash rate when i use the same card. 7990 though, nice!! would love to try one out for DMC and Saints row. 

yea, now that it is hashing properly I am downloading the included games and getting ready for that.  if I add a second one it should outperform my 4x 7950 rig and still be nice and contained inside a closed case ...  the only thing I don't like about my 7950 rig is that it has to be open air ;D

adjusted voltage to 1.08, temps are down to 80/73

Anybody working with this card have anything to add?  dare I try 1.05??  ;)

thinking about getting a 7990 now :)

It's great for what it is... 2 cards on one slot.  But because those 2 cards are automatically crossfired together it becomes a huge pain to disable the power management and make them clock/hash the way you want them to.  There are several methods to make it work and everybody seems to have different rates of success with the different methods.  Like I said, now that it works, I am happy  ;D  but getting there was no fun.  On the flipside, because I had to do all that I should be able to crossfire in the next card, if I add a second one, and I will be all set for both gaming and mining with no need to switch configurations or cables.  My case has one empty fan slot left which I will probably need to use and just hope that the whole thing will stay cool enough while closed.  Cross that bridge when we get there I guess, gotta mine for a while before I can get a second card ;)  Overall I would recommend it though, especially for part time gaming since it comes with 8 games.

Just don't buy them all up before I can get my second one!  :D

are you still stable at 1.325mh/s?

not exactly.  I was changing my settings bit by bit to see what I could do and it kept locking up on me.  doesn't look like I can get any more out of it. I did have it up over 1.4 but it was not at all stable and 1.35mhs but it would run fine for a few hours then crash which I thought was weird.... so no, I'm still working out all the kinks but I think my original numbers were pretty close

cool.  I just ordered my 7990  :)

I will also be doing a lot of tweaking so maybe we can work on this as a team.

yea, just let me know if you need a hand, i can probably dig some useful links out of my history.

basically, you will install catalyst / drivers and msi AB latest BETA.  reboot. open regedit and search for enableulps then change every value you find to 0.  it takes a while, just keep cycling thru (F3) and changing until regedit tells you it found them all.  then make sure AB is closed and go find that atipdlxx.dll.  put it in the AB program folder.  reboot. now you (hopefully) can change the voltage on your card with AB.

there are other methods but of course the last one i try is the only one that worked for me. ymmv  ;)

i have seen people post hashrates up in the high 1400's kh/s, but mostly 12-1300's.... as we know all cards are different so let me know what you can get out of yours.

as of right now I am hashing with the above posted settings, voltage 1.08, g 1, core 1050 mem 1675, avg 1.333mh/s, temps 83/74, running for over 4 hours now.  if i try to bump the mem clock to 1700 it works fine for a while at 1.35mh/s and locks up after an hour or 2, even at voltage 1.1, so I guess I am squeezing all I can out of this one.

mass what are you cgminer settings?

cgminer --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256

shaders 2048 thread concurrency 24000 g 2 w 256 i 20

i have seen a lot of people suggesting 8192 but i get hw errors with it

word of warning...  setting up mining was the first thing i did with my new setup.  after that i started setting up my steam account and downloading in my games.  the game installations changed my registry back to enabled ulps.  so i had to cycle thru the registry again and change all those back to zero in order to mine again.  if you install a game be sure to double check your registry before mining

-I 13 tc 8192 -g 2 that's all you need
i dont know what the f*ck is going on...on techpowerup,guru3d..and all the others site,power consumption of 7990 is about 350-380W
but when we tested 7990 with scrypt mining,the real power consumption was ~ 1050W (at 1.08volt,speed 720khash per core) ...
it's ridiculous because ref 7990 has 2 8pins =300w,pci-e = 75W....

 ??? ??? ???

i tried those same settings...  hw errors for me at 8192 tc no matter what the intensity / clock speeds or other settings... weird.

that power consumption can't be right.  i am running mine on a 1000w psu with an 8 core cpu, 32gb ram, wifi, and a 1tb hdd.  if the card alone were pulling that much power the system wouldn't be stable.  guess i better plug it into the killawatt and see what my system really pulls while mining.  some of the reviews i read put this card at 500w under load, i'll post back with my readings in a bit 

hmm...have you tried to reinstall your windows yet ?
Install Windows 7 or 8 (32/64bit,up to you) --> 13.1 CCC (you only need to install sdk and driver) ->start cgminer with those settings
if possible,you can give me your Teamviwer ID,i will config 4u :D
//~ 1050W for 2 7970 at wall

win7 64 bit / 13.4 ccc...  i have tried a few different driver versions without much difference, not sure if i did 13.1 though.  new system installed windows less than a week ago  ;D  I can always go back and give 13.1 a try to make sure though.

i know this is 2x 7970 on one board, but it's not quite the same as 2x actual 7970.  my killawatt reads about 230w at startup, 150w idle, and is bouncing around between 600-620w while mining.  so the card is definitely pulling less than 500w...  maybe 400-450w? not sure how i can test the card independently of the rest of the system.  it looks like i will need to go with a new psu if i add another 7990, but i knew i probably would anyway.

(edit)  just for reference, my 4x 7950 system pulls about 1.1kw and hashes at twice the speed of this 7990.... so it is right about where i was guessing it would be

@mass another dumb question how do you know you have "Sapphire 7990 (Tahiti)"?  I thought both GPU's were tahiti but the combined board and GPU is called Malta.

Also why do you use "cgminer 3.1.1/ catalyst 13.4" I think i have cgminer 3.4/catalyst 13.8".

Should I downgrade?

I'm asking because I can't really stabilize this card and I've tried several settings.

you should install 13.1 instead of 13.4  ::),uninstall in control panel,and then using driver sweeper to "clear" again :D
trust me :)), 7990 is as same as 2 7970s

if it is the same, why am i only pulling ~600w?  not trying to be a smartass, just wanting to understand all the inner workings of it  ;D  i am downloading 13.1 to try out now...


i am using cg 3.1.1 because i just copied it from the other mining rig, was too lazy to go re download.  ditto on the drivers, i have about 5 or 6 different versions on my usb drive, but 13.1 wasn't among them  :D  i say tahiti because when i look at the devices available in guiminer (i don't use guiminer, but i have it  ::) ) it reads as tahiti.  maybe the board is called malta and it reads as tahiti because it is just 2 of them on one 'malta' board?

i did use 13.8 and didn't have any luck with it so yes i would downgrade.  not sure about cgminer, probably fine there but downgrade the driver.  13.4 was working well for me and i am going to try 13.1 in a few minutes.  did you turn off ulps and undervolt it?  what are your temps / settings? 

i have tested my 7970s too,using kill a wat
4x7970s run on P31+775 dualcore ~ 1200W at wall
but i still have one problem that i dont understand clearly
from techpowerup review,7970 ~ 270W,7990 ~ 350W
when mining,7970 ~ 250-300W (depend on which voltage )..it's normal,power consumption is as same as techpowerup's review
but 1 7990 ~ 500-600W  ??? ???

thanks guys I'm installing 13.1 now and I did a driver sweep.  I had a lot of extra drivers;)

man i hope this works i thought a bought a $600 space heater lol

at my place,i have to spend 840USD for 7990 lol  :'(

i am confused because you said 2x 7970 = 1050w, now you say 4x 7970 = 1200w, which does sound a lot better...  maybe i read something wrong?

(edit) whoops, wrong link   ::)
http://www.techspot.com/review/663-amd-radeon-hd-7990/page8.html

that review shows 7990 at 491w under stress, which is about what i expected from it


thcst8, did you turn off ulps and change voltage?  that made a huge difference for my temps.  i could run at standard voltage but it got up into the 90's in no time at all.  at lowered voltage it runs 83 all the time

whole system
http://www.techpowerup.com/reviews/AMD/HD_7990/23.html
http://www.guru3d.com/articles_pages/radeon_hd_7990_review,8.html
4x7970 = 1200W at wall (whole system include cpu,hdd,psu efficient...)
2x7990 = 1050W at wall (___________________________________) 1.08volt
psu efficient = 88%
combo cpu,hdd,...etc ~ 50W

for some odd reason 13.1 will not install.

never mind i had to reboot again that was really odd

i am having the same issue, rebooted several times, uninstalled ccc, manually removed files, ran driver sweeper, rebooted in between each step, disabled AB...  for some odd reason 13.1 won't even give me the driver as an option when i use the custom installer.

i just set up access to all my games and downloaded one... plus the blockchain i realllllly don't wanna download again, but it looks like i am gonna have to format and try with a fresh install of windows

try removing the video cards in device manager then add them back.

The temperature was slowly creeping up to high.

GPU 0 - 73.0C
GPU 1 - 79.0C
1.29 Mh/s average after 7 minutes

MSI Afterburner Settings:
Core Voltage (mV): 1100
Core Clock (MHz): 906
Memory Clock (MHz): 1000

Do I just keep changing the values around till something works?

those are a little high but not too high.  basically, yes...  take a look at other setting for 7970 and go from there

at 1080v core 1090 mem 1500 i was getting 1.36mh/s with temps at 83/74 stable

it can also be tough to make sure the voltage settings took / you got ulps disabled properly, for me cgminer wouldn't report the cards voltage correctly but i knew because temps would go down using the same settings.  just play around with a few different numbers for a while and see how your card reacts, then narrow it down to what works best

format and fresh install of windows, still 13.1 package won't list the display driver as an option in the custom installer.  can either of you share a link to where you got a working version?

http://www.techpowerup.com/downloads/Drivers/ATI_Catalyst/

nope... no drivers to be had.  it offers to install hdmi audio, vision control center, sdk, but no display driver

now this is getting on my nerves lol

did you get any better results with other clock settings yet?

well, i downloaded the 13.1 package from 4 different spots and none of them would allow me to install a display driver, same thing with 12.11beta.  i installed 13.5beta and tc 8192 works but only at i 13 and low core/mem clocks.  even then it is much slower than my previous settings.  i will play around with 8192 a little bit but i think my original settings are gonna be best for me.

yea...  not so much... everything i try with tc 8192 either runs real slow for me (1-1.1mhs), spits back hw errors, or crashes the display driver

so i will be sticking to 1.08v tc 24000 i 20 g 2 w 256 core 1090 mem 1500  for 1.365mhs at 83/74 degrees

was hoping to get over 1.4mhs with this card but i guess it's close enough  ;D

i've just tested other 7990s

damn that's pretty nice looking...  wish I could get mine to run like that  ;)

might revisit the 13.8 driver if I find the time

an other tweak,taking a look at rejected rate  ;D

tempurature also decreases

I get about 680 with my settings.... can't seem to make it do any better.  when I tried your settings I only got 550.... only difference is driver version though

my 13.8 driver installed and seems to work fine, but I got a failed package error during the install.  video transcoder.  I don't think it should affect anything but I am going to play with it and see if I can't make it install without any errors first

if I could get your settings working I just might take that 660 hashrate so I won't need a new psu!

850w... that's crazy   ;D

nah,you only need to install amd driver...otherthings should be ignored.

what exactly does the -g flag do?  I can't seem to find it in the --help

again with your settings my display driver crashes, but if i set it to g1 then it goes just fine but only at about 550khash

with my settings g1/g2 didn't seem to make any difference  (edit) before it didn't that is ...  now with the 13.8 driver g1 crashes my setings, but g2 works

so for now with 13.8- your settings g1 works g2 crashes, my settings g1 crashes g2 works

The -g <arg> setting is how many gpu threads to start, if you have only 1 gpu then -g1 with a TC of 64 * bit-width (or slightly less for me) or -g 2 with TC of (64 * bit-wdith) / 2 should be used, if you have a 7990 then -g 2 would be best, there is probably better settings but if i got a 7990 i would first try -g 2 and --thread-concurrency 16384 (i think the bit-width of 7990 is 256, i could be wrong though).

so if i run it with g2 in the command line but i have gpu-threads 1 in my conf file, which one take priority?

i should probably go change that...   :)

having exactly same problem like what happened to ronaldinho_07, two 7990 consumed between 1.1 and 1.2kwatts but basically it must less than or equal 1 kwatts with effective added

honestly I don't know but i would think that the command line args should supercede the config file args, at least thats how i would write it, so incase you forget you have something in config files you forgot about it would be overridden with whatever you have in command line as you must want that argument you set in the command line to be active since you typed it there while config files can be old...

but again just a guess.

(edit)

nevermind....   SUCCESS!!!!

something in the cgminer.conf was throwing me off.  no idea what it was, but i replaced my conf file with a copy of the example file and filled in the minimal amount there, left the rest of the setting to the command line launcher.

Hello ronaldinho_07

Can you please tell me which brand exactly you have?
Sapphire, MSI, Gigabyte, or which one?
Thank you.

HIS
but they are all amd ref card

just when i think i'm done ....

my 7990 has been stable hashing for a few days, and nothing changed on that pc as far as installations / configurations, etc

now suddenly it will overheat and cgminer stops.  i noticed it randomly stopped once yesterday and didn't think much of it, reboot and it ran fine all night / day.  today i opened up the windows and turned off ac since it got cool here and started looking closer to see if temps got any better, but they are actually worse.  the ambient temp is much lower but my card is actually heating up faster and going over 95 where cgminer auto stops within maybe 20 minutes

double checked my voltage, ulps off, etc... no clue why it is doing this all of a sudden.  any ideas?

I moved 2 of my case fans so they are sitting directly on top of the card pulling heat up and away from that side of the card, and temps are now stable at 80.  Weird that it ran for so long with no issues and then heat suddenly became a problem, but it seems to be cleared up with that.  Now if I could just figure out why my hashrate dropped  :D  not gonna work too hard over 30khs... just a bit annoying  lol

Yeah i think I have been using these settings now.

1080
1000
1041

It's not very stable and my SSD OS drive crapped out on me.

I'm in the process of reinstalling Windows

13.10 beta anyone ? ;D
http://www.techpowerup.com/downloads/2263/amd-catalyst-13-10-beta/

Thanks for the 13.1 tip ronaldinho_07. I'll try them after I give the 13.10s a whirl. lol

Lots of good info here.

let us know how it goes  :)

AMD_Catalyst_13.10_Beta keeps failing to install for me...

I'm running windows 7 64 bit ultimate.

is the whole thing failing or one part failing?  I had the same problem with it and the previous version mentioned above where some package was failing to install, but the driver installs and works just fine.  using 13.10 right now with the same settings and my extra fans keep it at 81/74 and lower at night.

also don't forget to clear out the old .bin files from your cgminer folder, when changing drivers and settings.  that was a stability issue for me

Ok ok.. trying them now. :D

Okay that gives me more hope. 

I had to re-install windows because my OS SSD crashed.

The 13.10s installed but windows didn't like the AODdriver sig.

@thsct8 Try the Catalyst uninstall utility. I avoid all other 'sweeper' apps like the plauge. lol

http://sites.amd.com/US/GAME/DOWNLOADS/Pages/catalyst-uninstall-utility.aspx
 

Thanks it looks like everything is working now.  Now I just need to start testing again  ;)

So far this is what I did:

Windows 7 64 bit Ultimate w/ SP 1
i7 920 (i know its old!!!)
6 GB

1. Download and install AMD Catalyst 13.10 (the install might fail but it still works) - http://www2.ati.com/drivers/beta/amd_catalyst_13.10_beta.exe
2. Download and install MSI Afterburner - http://www.guru3d.com/files_details/msi_afterburner_beta_download.html
3. Copied C:\Program Files (x86)\MSI Afterburner\Redist\atipdlxx.dll to C:\Program Files (x86)\MSI Afterburner
4. Open regedit and find "enableulps" and "enableulps_na" and replace 1 with 0 - just press F3 to find next
5. Reboot computer
6. Open MSI Afterburner and press settings
7. Check "Unlock voltage control" and "Unlock voltage monitoring"
8. Have fun!

Okay I am sitting pretty at 1.3ish mh/s with these settings:

GPU 0 - 74.0C
GPU 1 - 66.0C
1.29 Mh/s average

MSI Afterburner Settings:
Core Voltage (mV): 1050
Power Limit (%): +0
Core Clock (MHz): 1000
Memory Clock (MHz): 1250
Fan Speed (%): 100

cgminer settings: --thread-concurrency 8192 -I 13 -g 2 -w 256

Also this setup is more stable using the 13.10 drivers.  

did you try core 1050?  that's the only difference in my settings and i am getting 1.43mhs, but my temps are higher too, 81/73

if core clock were 1080mhz,mem should be 1500
otherwise,trying 1050/1250

thanks I'm down to 1050 now and it looks stable.

I'm now looking into water cooling but I have no clue what I need to buy.  ???

I have my eyes on the Swiftech Komodo HD7990

http://www.frozencpu.com/products/21261/ex-blc-1527/Swiftech_Komodo-HD7990_Full_Cover_VGA_Waterblock_w_Backplate_KOMODO_HD7990.html?tl=g30c309s1876#options

any long term issues? upgrades?

what hash and watt (at wall) are you currently running at? I just saw the values that ronaldinho_07 posted earlier (~850W - 1150/1200W)

I am figuring if the 7990 setup will give me better hash/watt than a 7950 setup or any of the new R9 cards.
Any suggestions?

No issues, no changes...

My 7950 setup has 4 cards and pulls around 1100w at the wall for 2.5mhash.  The 7990 box is meant to be a gaming pc that also mines... but I haven't been gaming much on it lol.... maybe when mining doesn't make sense anymore I will catch up on my gaming  ;D ...  it pulls around 600w at the wall for 1.4mhash

I would go with 7950s if it is a dedicated mining only rig, the price difference in cards isn't worth the slightly better hashrates IMO.

at 27 euro-cents per kwh + going up next year it so much is worth it.
(or not mining at all) ;-)


that means your 7950 setup is working on the "high hasrate" side and not power optimized, right?
what about the 7990? do you feel it is setup at its speed limit, or more for stability, or for saving power?

no, both of my setups are undervolt/overclocked and running about as fast as I could get them to be.  you could run either of these setups slower than I do and save some power, but at that rate you may just want to buy cryptos instead of video cards + electricity

You're getting 1.43 from this one card?
The temps are okay, mine are usually around 80-84 on both GPU's (2x 7950s).

Yes.  To be fair, this one card is technically 2x 7970 on a single bus, but yes I get over 1.4mhash with my 7990.

My 7950s run at / below 70c, they do 640khash per card and are volted down to 1100... can't remember what clock speeds I am using

I didn't volt mine down. How did you do that?
Which models do you use? Could you provide cgminer configs for comparison?
