Title: 7970 MAXIMUM KH/S ONLY 600???? *****1000 DOGECOIN REWARD****
Post by: evovi on January 27, 2014, 08:28:24 PM
Hey guys,
I have a sapphire 7970 and I just cant get this thing above 600kh/s  ::)  Ive tried everything i can think of. First person that suggests something that gets my 7970 over 650kh/s ill give you 1000 dogecoins!!  8)

I know this card has more to give, whenever ive tuned other cards to their max you start to notice abit of system lag, but Ive never experienced any lag with my 7970.

as soon as I change any of the following my kh/s drops alot.
higher thread concurrency,
lower thread concurrency,
more than 1 thread,
higher intensity,
lower intensity,
increase memory clock,
increase gpu clock,

temps are always good and VRM's arent getting hot either

im using CGminer 3.7.2 on windows 7 x64 sp1

currant settings:
"intensity" : "13",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "2",
"thread-concurrency" : "20400",
"shaders" : "0",
"gpu-engine" : "1150",
"gpu-fan" : "65-65",
"gpu-memclock" : "1375",
"gpu-memdiff" : "0",
"gpu-powertune" : "20",
"gpu-vddc" : "0.000",
"temp-cutoff" : "92",
"temp-overheat" : "86",
"temp-target" : "80",
"api-mcast-port" : "4028",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "1",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "30",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"





Any help tuning this would be much appreciated!!!   :)

use sgminer 4.0.0
i13
lookup gap 2
tc 8192
powertune 20
engine clock at stock
mem clock at stock

1 find better tc your card start. (multiple of 2048)
2 find high mem your card work (1500 often is a good deal, but card can work over 1800)
3 find high engine your card work (start about 60% of mem value and add 5 per time, good deal are engine = 0.70*memclock)
4 set intensity.

sgminer, works better than cgminer, it is based on cgminer but fixed for only script minig.
only this, can improve your hashrate, after start you only have to find your best setting for best performance in hashrate or in hs/W (if power is not cheap).

if you can, post your batfile and results.

How are you determining your thread concurrency? From my experience, higher concurrency is not better for these cards. Try removing the concurrency line from your .conf file, deleting your bat file and seeing what it defaults to. That will give you a good starting point for where you should be.

Your clock speeds need some tweaking. Your core clock is a bit high and your mem clock is a bit low. Try something like 1040 core clock and 1500 mem clock and see where that gets you. These cards can be massively overclocked with few hardware errors but they do get hot so make sure your ventilation is good.

Try it with:

core clock - 1040
mem clock - 1500
intensity - 13
gpu threads - 2
thread concurrency - 8192
everything else the same as you have currently and report back.

tried sgminer 4.0, gives the same exact performance as cgminer with my setup. With a TC of 8192 im able to push the mem clock to 1500 stable. and engine clock to 1125, I havent found any 'sweet spots' when overclocking (5mhz increments). increasing the intensity over 13 results in lower khs and HW errors. Increasing the TC above 8192 lowers my khs until i hit a TC of 20400

with a TC of 8192, 1500mem and 1125 gpu im getting 595khs, (all other settings are same as in first post)

I tried your settings, im getting around 550khs with an intensity of 14, I 13 is around the 450 khs. (first time i have ever seen an increase in khs with an intensity above 13) I 15 gives HW errors

are your "g" command set on 1 or 2? if it is 2 set it on 1
you will set the bat file with:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
sgminer.exe -o stratum+tcp://xxxxxxxxx -u xxxxx -p xxxxx -I 13 -g 1 -w 256 --thread-concurrency 22528 --auto-fan --gpu-memclock 1500 --gpu-engine 1110 --gpu-powertune 20 --lookup-gap 2

before to start this setup, look on your sgminer or cgminer folder and delete the .bin files (like this: scrypt130511Thaitilg2tc20480w256l4.bin)

try several tc value, choice the highest your card start

dont forget that command "lookup-gap" is a comand who work with memory, so for high results, set it to 1.
if you undervolt your card and try to find best result saving more power possible, set lookup-gap 2

this setup is alredy overclocked, dont overclock over again.
how is voltage of card? stock voltage? or it is undervolted? use the software "gpu-z" for have it.

the -g command sets how many threads are used, and the results from 1 and 2 threads are above, I have tried many different TC settings,the best for my setup are 8192 and 20400. lookup gap 2 is the highest performance and thats what ive set it to. stock voltage

Having the "shaders" value at 0 means that it will default to whatever the native value would be for the GPU so changing that won't do anything.

OP; What is the exact model number on the sticker on the back of your GPU? It should look something like FX-797A-**** If it has a V1.0, 2.0 or 5.0 list that too.

I would say you might need to flash a new BIOS to your card but getting ~600 is higher than most people(including myself) get without a BIOS flash. This tells me that you have a setting issue. If you tell me the model number I can help tweak it.

I think your card may be too hot, do not trust your sensor completly, set your fan speed to 100% and see if the hashrate increase

People had bad luck using those cards but they are as good as (better than?) others.

What kind of 7970 do you have ? I'm running a rig with 5 Sapphire 7970 VaporX ( 11197-12-40G ) and at first it was a slooooow 550 kHs / card... Bad.
Now I can get 700-710 and its stable as a rock.

The key was :
1 - flash the card bios ( for me Sapphire.HD7970.3072.120926.rom was the right one )
2 - Update system drivers to amd-catalyst-13.12 and amdapp_2-9 (I'm runnig Linux, don't know if it's the case for you).
3 - Those settings are important :
"intensity" : "13",
"thread-concurrency" : "8192",
"gpu-engine" : "1040",
"gpu-memclock" : "1500",
"gpu-powertune" : "0",
"gpu-threads" : "2",

Ask me if you need more informations about flashing the bios, its not an easy part if you have not done that before

Take a look at my rigs on my pool main page (https://www.mining-pool.co.uk/)

thanks for your help!! My card is a sapphire 7970 (stock cooler) exact model is above in another post, Yes i have flashed bios, only a week ago i flashed another card of mine (a 7950) made a noticeable improvement. Ill give it a shot and report back

I was digging into my bookmarks and I think you can have a look at these links :

1 - find an appropriate ROM bios for your card here : http://www.techpowerup.com/vgabios/index.php?manufacturer=Sapphire&model=HD+7970
2 - instructions for flashing with atiflash from here : http://www.cryptobadger.com/2013/10/undervolting-in-linux-via-modified-bios/ ( just skip the part concerning the bios edit )

Notice you must run atiflash from a DOS flash usb stick. It wont work if you flash directly from windows.
You will also need your actual bios version (see picture) to get a compatible one from link 1

https://www.mining-pool.co.uk/img/bios_flash.jpg

when at the DOS command line, you get the card/adapter number and the bios version using this command:
Code:
atiflash.exe -ai

For flashing (DOS command line):
Code:
atiflash.exe -f -p adapter_number your_new.rom

why cant I use atiwinflash to flash bios???

I didn't used atiwinflash but i would say it "might" work. The important thing to notice is that you can't write a bios correctly on machine where drivers are installed. I know it because as you I failled to flash the bios this way. The result is a bricked GPU and there is no other way but flashing the original bios back, if possible.

So the good reciepe for flashing is : get a compatible bios from techpowerup, flash it using a win98 usb stick in command line. The atiflash.exe I used was v3.99 as 4.17 was not working.

Can you give me the reference of your bios like 015.022.000.001.000000

my bios is 015.012.000.004.000346  if you can recommend a particular bios i should try let me know. and i will try flashing it using a bootable usb stick, atiwinflash has worked in the past for me. but maybe i got lucky? cant brick my cards dual bios  8)

and yes you are right. I have another mining pc with a 7950, and I run it at I 19. and as you mentioned we are talking about a 7970, and it doesnt like anything above I 13

I get 650khs on my 7950, but if I do -i 13 my khs is significantly lower

nice hash rate, but.. how many wolts?
i run a 7950 undervolted at 1.049, and it run stable @556kh/s for a consumtion of 188w (only the card) 265 at the wall.

so i'm trying to reach best result Khs/watt, actually i'm around 2.96khs per watt, but i think it can do better.

for OP you search best performance in Khashr or best profit?

for best profit, see this thread: https://bitcointalk.org/index.php?topic=395004.60


EDIT: if i run "-g 1" command, i have best results in hashrate at I 19, I 20 few more hashrate but lot of reject, I 21 and above khash drop a lot.  if i run "-g 2" command, i have best result at I 13, oll the others hashs drop. have a sapphire hd 7950 cod. 11196-19-20g

yesssss, I was about to suggest that, too :-)  Thanks Silvano.

I almost physically crawled into my XFX 7970 ... and it's all documented there.
Would be interesting to see for me, how similar/different a sapphire 7970 is.

Happy mining!

Try these settings, they work for me on my Gigabyte R9 280x (rebranded 7970) and I get 720-730kh/s with 0 to very low HW errors/rejects



--scrypt -o stratum+tcp://Pool:Port -u Miner -p password -g 2 -w 256 -I 13 --lookup-gap 2 --thread-concurrency 8192 --gpu-engine 1055 --gpu-memclock 1500

You should be hitting over 700kh/s with those settings mate ;)

If not adjust your GPU Engine & Memclock to your cards settings if different to above.

(Use with either cgminer or BFGminer)

my bios is 015.012.000.004.000346  if you can recommend a particular bios i should try let me know. and i will try flashing it using a bootable usb stick, atiwinflash has worked in the past for me. but maybe i got lucky? cant brick my cards dual bios  8)

I would try Sapphire.HD7970.3072.120926.rom (http://www.techpowerup.com/vgabios/129658/Sapphire.HD7970.3072.120926.rom) with the settings and howto I posted before. Let me know what you get, it's something I'm interested in. Also remember you have a switch on the card whitch let you chose between 2 positions for flashing (switching it back permits to 'unbrick' the card because you switch to the standard stock bios).

Considering what has been said about undervolting the 7970s, I would say from my experience that you cannot have high kHs and low consuptions ont those cards (7950 can). I tried to undervolt Sapphire VaporX 7970 (I modified Sapphire.HD7970.3072.120926.rom (http://www.techpowerup.com/vgabios/129658/Sapphire.HD7970.3072.120926.rom) to 1,081V ) but you instantly get something instable in  hashrates > 600kHs.

Thanks..... i tried flashing the bios you mentioned, flashed successfully in DOS. But the card doesn't like the bios and failed to boot. So i flashed the stock bios back. Can you suggest another bios to try?

Yes. Make your own. Take the original BIOS, and tweak it, e.g. with VBE7.

OK I found something which should do the trick in the bunch of my bookmarks :

Also when you search for problems on a particular card you should use its reference like 21197-00-40G in ggl.

700KH is on the way

Hmm very interesting...... I flashed the 280x bios and the card works fine but...... im having some problems with the drivers  :'( . I installed the exact amd drivers he mentioned and AMD catalyst just says failed to load drivers. If i switch back to stock bios AMD catalyst starts and works as normal. I have a 2nd PC I might chuck the card in that and see what happens


EDIT: tried the card in my 2nd pc, exact same problem. without any drivers it boots to windows fine, but after installing AMD drivers it blue screen's on boot.


x2 EDIT: found this fourm http://www.overclock.net/t/1433293/flash-7970-to-r9-280x-bios/80     seems im not alone with this problem and it seems that a reference 7970 cant be flash with a 280x bios, If you have a non reference 7970 then you can flash a 280x bios....... and yes i have a reference 7970  :'(

Wow , we have very bad luck with this card. It seems you 'll have to learn a little bit of linux. Also I would suggest you contact the other guy from the weminecryptos forum as it seems he own the same 21197-00 card as yours (see https://www.weminecryptos.com/forum/topic/1080-low-hash-7970-please-help/?p=6718)

Is your card a 21197-00-40G

This is going on for too long, and you risk killing your card with unnapropriate BIOSes, not to speak about the peace of mind you're losing. People posting random stuff for the sake of a bounty doesn't help either. I'm going to say this for the last time: go and post on this thread: https://litecointalk.org/index.php?topic=12369.0 Donate him your 1000 Doge and post your ORIGINAL bios.

Wait and grab your modded bios, edit the voltage to, say, 1081 mV with: http://www.techpowerup.com/forums/threads/vbe7-vbios-editor-for-radeon-hd-7000-series-cards.189089/. Or better yet, look into drakoin's undervolting/power saving thread. Donate him some doge too.

Then go to the link mentioned above, pick sgminer and those .bin files on the top comment: http://www.reddit.com/r/litecoinmining/comments/1va8g2/ann_sgminer_400_release/

Copy those bins to the sgminer folder and either use on your config:

"thread-concurrency" : "24000",
"gpu-threads" : "1",
"intensity": "20"


or

"thread-concurrency" : "8192",

Nice. Now, did you set a low voltage on the bios with VBE7, e.g. 1081 mV or even 1050? Did you download the optimized .bin files?

IMO, it cannot be too difficult to do a binary diff (using, e.g., http://www.softpedia.com/dyn-postdownload.php?p=154713&t=0&i=1) on each of his three types of mods which were dependent upon the ram chip identifying program he used and which is posted at

http://bal3wolf.centelia.net/DRIVERS/TOOLS/Tahiti_GDDR5_Info.zip

It would be a nice thing to post the results of such a study, as the stilt oddly was secret about his mods.  Perhaps he is applying for patents or something?

I suspect/believe he's under NDA.

However the community can indeed work around. Not only a binary diff, but use AtomDis http://cgit.freedesktop.org/~mhopf/AtomDis/ to dump bios info and figure out differences. I've been too busy/tired/lazy to do so myself.

Was anyone able to archive The Stilt's bio's mods from his 7970/280x post? All the files in his dropBox links have been deleted:
https://litecointalk.org/index.php?topic=12369.0 (https://litecointalk.org/index.php?topic=12369.0)

My XFX 280x runs a crap hash rate 500-550kh/s regardless of the config parameters that I use (I've tried every config option that people recommended in his, this, and other threads).

I think my card gets throttled because hash rate jumps up and down in cgminer/cgwatcher.

virtualreality69, when exactly did the files get axed?  

virtualreality69, the throttling is something you need to fix on your own.  Do you use trixx?

Given what we know, and my post which Wipeout2097 further improved, it isn't a surprise.  I do wish I knew the motive behind this.  I don't need to know who is behind it.  Just a motive.  If anyone reading this knows, pm me and you'll get a very pathetic offer for some altcoins I've mined.  

Here are 3 options:

Option 1: pm the persons(s) who had requested your exact bios.  

Option 2: Actually, any bios will work if you use my proposed method and are willing to work a bit.  I could probably give you the one I snagged.  Do you want it?  

Option 3: Suck it up.  The same people who were able to get the dropbox files deleted might go after you too!!  Might want to not do it or do it on the down low.  If you have kids, this is your safest bet.  You think I'm kidding...

I dont know exactly when he removed the files, but he was still posting about 2 weeks ago.

I have trixx installed, but dont use it for much.  What do you sugguest doing with Trixx to help fix throttling? My temps are fairly low (76-77C) and the fan rarely spins above 40%.

As for why it happened I dont know. Someone mentioned that he may have signed with a new company and has an NDA.

Throttling if any is due to boost and/or high temps.  Disable any boost and use trixx to set your fan at 100%.  Any temps above 70C are high IMO, expecially because the heat from the gpu heatsink prevents the ram from being cool.  

It is normal for some fluctuations.  Post a video of the cgminer or sgminer using option "-log 1".
