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

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

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

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

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

can anyone confirm whether these hdmi to vga adaptors can work as a dummy plug together with resistors? thanks.

Sure thing! Just stick the 68 ohm resistor legs into the specific vga plug holes and bingo.

I had instaled Water cooling and after that Cgminer only starts with black screen (no stats)
It starting like before - check pools, etc.. but after that only bin file is created and seems that GPU calculated something but - no stats at all.. i cant see HashRate

Sounds weird, but plug the fan in, then remove it. Do this after windows has booted up.

After you've done that, start cgminer. No more black screen.  Grin

I am using one of these so I no longer have to plug a fan in.

So AMD just annunced the new line of GPUs. For bitcoin mining they wont be good compared to ASICs but how about litecoin? What can I expect from the 290X? Hashrates higher than the 7990? What do you think and whats your opinion on the card?

time changes so fast, scrypt asic's so close

Hello:

I have four MSI 290x cards going in my 5 PCI Gigabyte 990FXA-UD5 motherboard. I get about 820kh/s per card. 8G of memory. AMD Sempron 145. It is much easier to get 900K with one card from what I have read.

I am using TWO 1200W power supplies for a total of 2400W. Using a dedicated 20amp breaker in my house. I would not use any type of outlet in your house. A 15amp breaker won't just go at 15amps, it will go much higher. But you will begin to melt the elements in the breaker. When I tried starting up my four 290x on my 15amp bedroom circuit my lights dimmed. Now it is in the basement on a 20amp. The great thing is that it doubles as my basement heater.

I am using NO external fan. The exernal fans do not do as much as the internal fans. You NEED a program like MSI afterburner and have a fan chart. If you are running 95 degrees, then your fans should be SCREAMING. For some reason the defaults are just to turn the fans on low when you are at 95 degrees. 95-99 degrees is shutdown time. You should be running about 82 degrees or less.  Right now I am running 70-75 with only the fans inside of the card. I don't know about putting an external fan on, maybe in summertime. Pointing a huge fan at your expensive video cards might be pushing dust into them. Just a thought.

Using Kila-watt the motherboard and first 2 cards are 850W at 3.4 Gh/s
Using Kila-watt the other two cards rate at about 550W at 3.4 Gh/s

I use MSI AFTERBURNER, but make SURE you disable overdrive (with 4 cards anyway) and also disable crossfire when using four cards.  MAKE SURE you enable the 2nd tab for the fan chart program.

I use CGIWatcher 1.3.4.4
I use Windows 8.1 Pro all updates
Latest AMD Catalyst drivers

--thread-concurrency 33792
--worksize 256

Core clock 1025
Memory Clock 1500
Power Limit + 20%
Apply overclocking at startup ON.
5-7 failover sites (at least have a few)

To answer the question WHY 290x, that was the only card I could get my hands on at the time.  I don't know about running four 280x would it also give slower then advertised has rates. Anyway, it will take some time for me to get the investment back, but I believe the machine will be stable after its paid off.

I'm pulling more like 980kh/s on similar clock/engine settings from a sapphire 290x. When I was stuck on 12x shaders I was locked at 880kh/s, but I noticed adding 10-50 to the TC would let me run higher on the same clocks. I stopped around 33999 because for some reason going higher would hamper my hashrate. I could push memory out to 1700 and get to 1.004mh/s, but that was an engine clock over 1050 and it went down some time later. Fun to mess with, probably not good to run like that.

Anyway, something to try. If you get favorable results would you please let me know  Grin

I already posted all this, sorry for the brainfart  Cheesy

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


I solved this problem by adding another 4GB memory stick to my rig to up the memory to 8GB.

To repeat, to get the Thread Concurrency above 8192 or 28160 which is 10x 2816 shaders it seems that the pc needs more memory.   I have no idea why.

Also, I read on here that TC should be at ~ 12x shaders, or 33792  was good, but i got better performance at 32765.  875 stable Khash/sec.

Also, I am working to see if adding or removing --auto-fan helps hash rate.  does anyone know about this?

EDIT:   I just tried with and without the --auto-fan option, and no effect on hash rate.

Get those cards on some risers mate. Heat is lowering your hash rate.
I ran 3 x Sapphire 290 and was getting between 790 and 830kh/s. (Note that is 290, NOT 290x)

Finally got my hands on pci risers so I could spread them out more and all cards are now rock solid on the same figure. 865kh/s.

Many BS in this thread so far.

Anyway 290X is too expensive to be a good deal for mining. Also 290 and 290X as a whole are not suitable for mining at least models with the reference cooler due to their extremely high operating frequencies that will melt the card once winter is gone. On the other hand due to current great price gap between 290 and 290X I can say that 290 is much better than 290X. I had a 290 running on my system with about 850kh/s at default frequencies and above 900kh/s at 1050@1450. Noise though is unbearable and temperatures are skyrocketing at minimum about 85C. I returned the card and got 280X.

290X/290 is not more power efficient than 280X. Even if it is so then the difference is really negligible. I see people mining with cards for 500E and mobos for 200E and can't stop wondering how are you going to make profit with such poorly chosen hardware ?
