are you sure you are on a 64 bit sgminer build?

there is a little windows compile guide, including x64 and visual studio, right into sgminer:

https://github.com/sgminer-dev/sgminer/blob/master/winbuild/README.txt

I'll look into building binaries for cards other than 290 and 290x but being unable to try them, I can't tune them.
This means they might not run as fast as they could.
Some 290 binaries (hawaii) run on 280 and 280x as welll (tahiti), so people please try that.

Using hawaii binary on tahiti does not work

[14:23:36] Error -11: Building Program (clBuildProgram)
[14:23:36] Internal error: Input OpenCL binary is not for the target!

Reminder, these are the chip classes to compile opencl for:

Hawaii = 290, 290x and 295x2 (works)
Tahiti = 7950, 7970, 7990, 280 and 280x (may work with the hawaii binary)

Other smaller cards may not work at all or be very slow with the hawaii binary.
If one card of a group works, so should the others of the same group; es. if it works on 280x, it should work on 7950 as well.

Hmm,

I'll go accross many threads mentioning it, when a 32bit bin is avaliable or a 64bit sgminer pre-compiled is avaliable

You'll be surprised at how many of us don't know how to compile sgminer from source  

Should help the crowdfunding appeal

Also, bins for 270x, 280x, 7950's, 7970's and 7990's would help the crowd funding appeal a lot

0.147 BTC donated so far, thanks guys! :-)

Hmm, wouldn't that invalidate the GPU warranty

That's because the fan is running slower.
6 degrees is really a lot just for thermal paste, I must try that!

Nice work.  That card is running a tad hot even for a reference card.
I replaced the thermal paste on my own card and temp went down from 84 to 78 degrees, power draw went down 10W too.

Could you be kind

And post a pre-compiled version of your Lyra2 sgminer 64bit for this thread to us, please

Hello all,

I made a faster Lyra2RE kernel, currently it can do 1780 Kh/s on an r9 290 at core clock 1000 and memclock 1500.
It also works very fine at 1740 Kh/s with reduced core clock of 835, so very low power.
Lyra is very dependent on memory performance, so depending on the ram chips you have on the card, the speed may vary sensibly.
People know me for my opensource works (including the groestlcoin opencl kernel), but now I'd like to try something different, kind of experiment, inspired by other people in this forum.
I will receive donations for it and send the binary to the donors. After a period of time, or if I get enough BTCs, I'll make it public (sources included).
I've had bad experience with donations in the past, let's see if Vertcoin people are different!
And know that if you leak the bin, diff will go up and you'll get less coins! ;-)

Donation BTC address: 1H7qC5uHuGX2d5s9Kuw3k7Wm7xMQzL16SN

Current donation total: 0.127 BTC
Target: 3 BTC
Minimum donation for getting the bin: 0.02 BTC
Expiration: May 1



Note: in this picture I'm using a modified sgminer that provides another 2% increase at 835 core clock; I will not release this at first because it would be another sgminer fork for little gain.

Note2: the bin file you will receive is compatible with the latest djm34 sgminer, 64 bit, found here https://github.com/djm34/sgminer

may-be it would be easier to use the visual studio for that, otherwise you'll need a x64 version of mingw (as well as the corresponding dependencies)

normal temperature: it's a reference design, it reaches 95 before throttling.
and that card is mining at 92-95 C for a year now.

Having not followed Lyra2RE at all, what kinf of % increase is this over the public kernel? Wondering if this might be worth firing up a few 290x/290 cards for.

Can anyone post a pre-compiled version of djm34 Windows 64 bit sgminer, as I can't find a tutorial on how to compile it from source

Thanks
