I was finally able to pull nearly a solid mh/s from one 290x for over 6 hours stable  Cheesy

Nothing really ridiculous either, just 1040/1500 at a TC value that took me quite some time to find. If you want and try for the same, start at 12x shaders for TC and find the best core/mem ratio. Then, just start increasing TC 50-100 each swat till the hashrate suffers. I never had to deviate more than 5mhz on core clock from the 1040 I started at. I'm right under 34000 for a TC value, but if I had to guess I'd say your results probably won't exactly match mine.

Lots of rejects, I was trying a new pool. Ignore the fan speed, don't know wtf is going on with that. Heat absolutely kills these cards too, I could show you a vid of what happens when I stall all my rad fans. The card shoots to high 70's lickidy split, and soon stumbles to 880kh/s or so...





I was able to get to 1.004mh/s, and it looked pretty damn cool having one card in the mh/s range in cgminer. It's not very stable though, yet  Grin

Yes. You need to go big if this is the case. But i think your hashrate is a bit off. 4x280x is a minimum 3000kh/s (owner of 3 different 280x, and all 3 hashes over 750kh/s), and 4x290x is a maximum of 3600kh/s( have still not seen any hard evidence for getting those to work fine over 890kh/s) .  

And IF you are going big, why waste money on 290x? A 290 does about the same for 3/4 of the price.

And another thing. When it`s time to sell the hardware, i belive you have more value left in a 280x than a 290x. People just don`t want to pay big bucks for second hand hardware.

can you share your cgminer configs for 280x, I have 2 but running around 720-730khash

Here's mine.  I get usually 800+.  Note, this is for ONE 280x

A question to all 290X owners here.

Why did you buy theese gpu`s? I can not work out how they can beat a 280X pricewice.
You're right.
1x 290X = 500 EUR
1x 280X = 250 EUR, so 2x280X=500 EUR
The final cost is the same.
with 2x280X will take more speed than 1x290X

true
but if you look at it like this.

4xamd 290x = +/- 1800 euro = 3600 - 3700 khash
4xamd 280x = +/- 1040 euro =  2800 - 3000 khash

so now thats a diff of about 800 euro's but if you wat to achieve the same hashrate at the 290x
you need to buy another mobo, cpu, memory, storage, powersupply and finally a 280x

and running 2 computers will have a bigger electricity bill.

so in the end you will pay more for 280x to achieve the same khashrate.
but thats only if your planning to build a strong rig etc

I miss the cost for long time power consumption in your calculation...  please can you add them...   :-)

there is no need for dummy plugs!
unless you have messed up your win/settings/driver, and deactivated powersave, all current cards run fine without dummy plugs!!

how do you guys get R9 290x working with cgminer?

whenever or whtaever I try i get the decrease TC increase LG error.

only way for me to mine with 290x is using Guiminer-scrypt


You don't have GPU_USE_SYNC_OBJECTS 1 and GPU_MAX_ALLOC_PERCENT 100 set.

Mainly the first, but the second is needed too.

As for a dummy plug, maybe a displayport to VGA or DVI-I so you can use dummy plugs? Or deal with it for now and hope for better drivers? I'm really counting on that last one...

i found something interesting today. on win8. my 5 sapphire r9 290's are hashing ~800khs on stock clocks. as soon as i overclock the hashrate drops to 600khs - no matter how high or low i overclock it. stock clocks give me that hashrate on 13.11 drivers. i tried 13.12 drivers today and on same settings all cards went down to 600khs. im back hashing at 800khs on 13.11, i disconnected the hdmi cable and took it to hashing room - now when i teamview into it windows applies the temporary 640x480 driver that dont let the cards hash above 600. greatly agitated by now. what would you recommend as a solution?

Hi all. Need some advice...cgminer crash.

Windows 7 Ultimate
4 R9 290x
Catalyst Version   13.11 (Driver Packaging Version 3.25.18-131007a-163536E-Asus)

Trying to setup cgminer 3.9.0 or Guiminer both which crash in 1-2 seconds stating "cgminer has stopped working"

Any ideas?

Thanks in advance

Use cgminer 3.5...

I tried 3.5.1 and no luck..never even gets going. cgminer just kinda pops up and closes when I double click .bat file.

My setting are:

timeout /t 10
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -I 19 --thread-concurrency 33792 -o stratum+tcp://coinotron.com:3334 -u JKLtCn.1 -p 123

Did you have to change drivers and which AMD Catalyst version do you use?
Sounds like cgminer is having problems with R9 290 (flashed mine). What are the other options to get up and mining?

Thanks
