AMD R9 290X?

[Samir_H]

It's readily available...

I suggest waiting for the r9 290, should draw less power and be slightly slower, whilst costing $100 less.

Any idea when they launch this card? I always though they launch it together with R9 290x...

Last info 5th november.

Thanks for sharing, was waiting for an answer before this...

I guess people didn't notice me emphasising bitcoin in my comment.

i think people just assume you weren't talking about wanting to go back to GPU mining of bitcoins.

[forevernoob]

Yeah why the hell would you wanna mine bitcoins with your GPU anyway?
Current difficulty is just too high.

Thanks for sharing, looks like I will pass until the price of the GPU drop..

I got a 280X and I'm able to get ~740KH/s @ 1100/1500, I love this card and I want to order 10 more!
Running @80C at maybe 30DB, its almost silent.


I really want to get a 270 and see if I can get 700KH/s, because its almost 100 USD cheaper

270x is a 7870 ghz card...you won't get more than 350-400 with it.

280X is a 7970.

Some power consumption numbers

6 Core AMD CPU
SSD drive
Watercooled GPU and 1 80mm fan
2 monitors hooked up

167 Watts at idle
415 Watts @761Kh/s @1085/1500

The card as it is now ($550, 300W, 95ºC, stock cooler) is a bad deal for mining. Better get 7990, 7950 or 280x

Who said it's bad that it runs at 95c? It's a safe temp for those chips...
As far as power draw, the guy who posted results reported 270w+- for 900kh/s, which is pretty decent imho.
The 290 non x should draw even less power and run cooler since it sports less SPs, and will probably overclock more. If you undervolt a bit you should be set with a par of em, at 400usd.

[Samir_H]

I read somewhere about flashing 290 with 290X bios, that could be interesting if it's possible...

That's probably just pure speculation...how can someone know that already It could happen tho, we have seen it in the past. R9800->R9800 pro or 6950->6970 comes to mind.

I guess AMD learned from those mistakes...

Wow, 270w is really good for that hash. Might get few if Alt-coin price go up...

Are they using the same chips?

Not the same chip, laser cut probably...AMD won't make the same mistake again.

Which one did you get?

I tried MSI TwinFroz OC Gaming (which failed after a week of mining) and HIS IceQ X2 Boost. Both freshly released 280X.

- MSI was silent and performed around 700KH/s at stock 1000/1500 with temp 80/81 C, really like this card, compact
- IceQ same performance at 1000/1500, silent but at a max of 68/71 C (+1 from me), only thing it's huge at 31cm length, but solid and hopefully long lasting

Haven't overclocked nor undervolted yet but if anyone could post their CGMiner settings for the same kinda cards maybe of help, I'm sure I can squeeze a little more out of them. I use

Code:

-I 13 -g 2 -w 256 --shaders 2048

Looking forward to see price and availability of 290 and 280 non X versions but as per the 290X it's a nono cos of the noise that thing makes!

Where did you see 95C? I don't think with nice settings it would go that high right?

I have two sapphire dual-x 280x cards, both manage right around 750kh/s with these settings.

otoh, who said it is safe? The company releasing a card with crappy cooler and wants to sell hardware? It's up to the end user to determine if he wants to keep at 95ºC a piece of hardware that costs him $550.

As far as power draw, the guy who posted results reported 270w+- for 900kh/s, which is pretty decent imho.

900 Kh/s at 270w is indeed decent. What is not is getting 900 Kh/s at 270W after paying $550. Compare with getting 750 Kh/s at $275 and ~180W out of the 280x or 650 Kh/s for $200 out of the 7950.

Nice, and do you have to have a have a watt tester?
