Topic: Can't break 700Kh/s with 280X Dual-X OC (11221-00-20G) (Read 8647 times)
I have some 280X Dual-X OC (11221-00-20G) card. I have a very high temp more then 88-90C. Have you any solution? Thanks.
I've switched to SGminer 4.1 and I wont be going back to CGminer.
Right now I am trying out all the supplied kernels in SGminer, a 48hour test on each one. When I started mining the only thing I was looking at was hashrate but after some reading I realised it's WU that's the most important factor here (Work Utility). Some kernels gives much better results that others but right now I only have 48h results for two of them:
zuikkis @ 1065 Mhz
GPU 0: 722kh/WU:649 (89.8%)
GPU 1: 722kh/WU:647 (89.6%)
GPU 2: 701kh/WU:644 (91.8%)
psw @ 1065 Mhz
GPU 0: 728kh/WU:665 (91.3%)
GPU 1: 724kh/WU:675 (93.2%)
GPU 2: 714kh/WU:665 (93.1%)
The WU should be 90% of the hashrate or higher. More results in a few days.

Thanks for the upload mezza550, I've followed the exact same procedure as you've stated here...
Very cool, will look forward to hearing about your experiments. Quick update for me:
- I disabled "Cool and Quiet" under for my CPU in the bios, as suggested by a user on this thread: https://litecointalk.org/index.php?topic=14951.new;topicseen#new, but it didn't really change performance.
- I switched to a different mining pool, Shiftcoin for a day and my performance was somewhat dramatically better, at least in terms of hashrate. All of my cards enjoyed a 10+ Kh jump, was getting 715,720,740,710!
So it seems that the type of coin you are mining and/or pool you are participating in can also sway these results. When you guys are testing, do you mine just one coin, or?
Good luck and don't forget to report back here. 
Thanks for the upload mezza550, I've followed the exact same procedure as you've stated here and can report very similar results for my 3x 11221-00-20G's -they hover around 700-707kh/s. My setup is pretty much the Cryptobadger rig: http://www.cryptobadger.com/2013/04/build-a-litecoin-mining-rig-hardware/
Now I'm wondering if I can get a few more khash out of them, It would be nice to end up somewhere around 740. What I'm going to try in order of importance:
1. Fine tuning the overclock.
Right now they are all on --gpu-engine 1065 --gpu-memclock 1500, probably can adjust the sweet spot further for individual cards.
Q: No performance gain by overclocking memory on 280X?
2. Going from cgminer to sgminer and try out a few other kernels.
3. Look at other Catalyst/SDK version combinations.
Right now I'm at Catalyst 13.11 beta 9/APP ADK 2.7.
4. BAMT
I tried ubuntu, went half insane trying to do the simples things in a broken UI, went back to windows. A pre-configured mining-specific Linux enviroment like BAMT should be better optimized and thus give slightly higher hashrate. Problem with support for Wi-Fi cards though.
5. Pray
The patron saint of miners is Saint Barbara, she might bless me with a few extra khashes

I get 750kh on both my windforce 280x using sgminer 4.1. I get even higher than that on my ubuntu install (775ish khash)
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
sgminer.exe -o stratum+tcp://localhost:3333 -u User.Worker -p password -I 13 -g 2 -w 256 --thread-concurrency 8192 --kernel alexkarnew --gpu-engine 1080
and yes you can use trixx while mining.

here my impressive result, notice the lucky vcore of the 280x, the other is an old 7950
Lucky you lol mine is all over the place right now, can't seem to break 690
I used cryptobadgers undervolting guide and mine currently run at 1100/1120/1100 fairly stable i think
http://www.cryptobadger.com/2013/10/undervolting-in-linux-via-modified-bios/ <---- link to guide
I'm going to do some more structured testing over the next few days. I'd be happy with 710 at this point

Next question can you use TRIXX to change the gpu clock while sgminer is working, or do you need to restart sgminer to see if what you've changed makes a difference
I'd also like to know more about this- and about Trixx in general with these cards. I did one test last week where I lowered the voltage to 1150 and my computer locked up pretty quick. Has anyone here successfully lowered the voltage with their 11221-00-20G? Is trixx the best way to do this, or using the vddc argument in sgminer? Or within sgminer while it's running?
Quick generic update, my rig is still operating at about the same level ~700-710
Any had it when they are changing settings on the cards and the card starts doing 300kh/s and no matter what you change it too after it doesn't change from that 
.
EDIT:
OK i think thats because when sgminer crashes or the drive fails i hadn't restarted the computer each time.

i was modificed the bios, but now i have yours bios.
This is my config:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
-o stratum+tcp://scrypt.megamultipool.com:80 --thread-concurrency 8191,8191 --worksize 256 --intensity 13 --gpu-threads 2,2 --shaders 2048,2048 --temp-target 65 --auto-fan --gpu-fan 35-90 --temp-cutoff 80 --temp-overheat 76 --lookup-gap 2 --gpu-engine 1040,1125 --gpu-memclock 1500,1750 --gpu-powertune -20,5
first is the card that don't work fine, jinix
second is my best card not jinix
all same card: 280X DUAL X, the second is bf4 edition!

Any ideas where I can get a compiled version of sgminer 4.0 to save me trying to compile it myself
Here's where I grabbed mine from: https://mega.co.nz/#!scgiiaaT!VvxjpA6KsURx2oMOm2t1GVvV9epWwC3nVncFPsUiZYw
thread: http://www.reddit.com/r/litecoinmining/comments/1va8g2/ann_sgminer_400_release/
no no i have elpidia XD and have 785khs with engine 1125 and memory 1750, the hinix don't work so fun, have 78° with 725khs, over vdcc i think
Would you mind sharing all of your settings (copy / paste arguments) please? Also you mentioned about voltage, are you using Trixx, or something else? And you're using the same bios I uploaded?
thanks!
Use SGMiner 4.0 instead of 4.1 for the optimized .CL and .BIN files to work.

thx for bios, but the card don't change, all time with 615 khs with only 896 engine i don't understand! (
edit: i dont know how, but now work well the card, and the second card have 780Khs XD ok consuming grow up, but now i have only 2 cards then i don't care)
Just to clarify, your card is now performing at 780Kh? Settings please! i don't understand! (edit: i dont know how, but now work well the card, and the second card have 780Khs XD ok consuming grow up, but now i have only 2 cards then i don't care

) Mezza I would also like to know how you used that 'optomized' BIOS file cos atiflash doesn't recognise it when I try. Maybe because its a .bin file not a .rom? I followed crytobadger's instructions like when I unvervolted my card and it still won't work
Did you use atiwinflash (in windows)? Or atiflash at a DOS command prompt (after booting in to dos only)? The .bin / .rom difference shouldn't be an issue as far as I know. Also this bios flashing thing is independent of any undervolting as far as I know.
Yeah me too. Proving harder than I had hoped too. The .bin file that you'll find in the sgminer folder has the name of a kernel file at the begining of it. Mine always seems to pick ckolivas.cl. I had the scrypt130511.cl file in the kernel folder, but it doesn't pick it and if i delete the others it doesn't work and I can't make the kernal argument work either... so far.
What does you .BIN file start with, I wonder what kernel your actually using then?
sgminer has serveral kernel files but i don't know why it picks a particular kernel

Sorry I've been absent here for the last few days. Life always getting in the way! So I took a look in my sgminer folder, and the .BIN file that my miner created is: "scrypt130511Tahitiglg2tc8191w256l4.bin". So it looks like it's picking up the right kernel by itself. I'm not specifying anything for that in my arguments. Maybe you could try making a copy of your mining directory and delete all the .cl files in that one except scrypt130511.cl? Or have you found a workaround in the last few days?
Some people have PM'd me about the vbios which has apparently vanished from dropbox. Here it is:
https://drive.google.com/file/d/0B8TxUyvOU-ZtVnoxQ0xVWDltMVE/edit?usp=sharing
Included in the zip are 3 files.
Use atiflash.exe at the command line (create a usb boot drive to go directly in to DOS, no windows). Personally, I recommend unplugging all of your GPUs except one and flashing the bios like that, one at a time and testing your windows boot up & mining for a few minutes. It's slow but you don't want to get in to a situation where none of your GPUs are working. Factory bios included in case you need to revert.
Some quick atiflash command:
Good luck and don't forget to report back here.

- factory_bios.ROM - factory bios for the card when the UEFI switch is not on
- factory_uefi_bios.ROM - factory bios for the card when the UEFI switch IS on (indicated by blue LED on top of the card)
- Sapphire_E24900-O46_AGR.bin - the modified bios.

- atiflash -ai (advanced information- same as before, but with more info)
- atiflash -f -p # bios_file.bin (this flashes the bios. -f = force overwrite, -p # = specify which GPU by number, bios_file.bin = the bios file (can be .rom or .bin)
