[VTC] Lyra2RE Vertcoin optimized miner, NOW WITH SOURCES!

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.

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

Hmm, wouldn't that invalidate the GPU warranty

that will, but it worths it. I did it for my 290x which was always throttling when hitting 94°c, and I runs now in the 70ish...
The old thermal paste had turn into some solid powder and was pretty ineffective...

Cool, here's my forecast for BTC price then, from another thread:

Price may around this level all of 2015 and only the block halving in 2016 will cause it to increase

Looking at the network hashpower, it looks like all the 1watt and 1.2watt mining equipment (some may be farms) is still functional, even when it is not switched on for mining 

Whenever, the BTC prices goes above $220 these farms and equipment are switched on - mine some BTC and immediately convert it into Fiat Currency, which causes the price to head back downwards below $219.

Therefore, their is still 362PTHs network hashpower, but it is only switched off when BTC is a below certain price benchmarks.

Around 362PTHs around $245 plus
Around 310 PTHs around $220 plus
Around 250 PTHs around $200 plus

Consequently, network difficulty will have to be held around 41500000000 right up to the block halving in mid 2016 

Obviously, when the block reward is halved mid 2016, the 1watt and 1.2watt mining equipment will need BTC price of $400 before being switched on, so price will definitely climb alot

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

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

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.

[pallas]

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.

ok, it seems I am out right at the first line "Windows 7 (if you are using Win 8 or above, you will need to use a VM Win 7)"... not sure what sgminer5 dev are thinking...   (there are way to build stuff without requiring a VM session... or some arbitrary windows version )

I'll try to build for Tahiti (even without the card) later. Will keep you posted.

Yeah, there will be quite a lot of development work done this weekend

[pallas]

Update: I've produced both a 32 bit bin for hawaii and a 64 bit bin for Tahiti, but they seem to be terribly slow so there must be a problem with the way I generate them (probably due to the fact that I do not have the card nor a 32 bit miner).
Or it could be a driver problem: please try 14.6/7, 14.9 and 14.12.

Pallas, this thread has made the news

No pressure on you then

Thanks!

I've been working on this binary generation thing this weekend and sent out a few links for you guys to test.
I will eventually aquire a 7950 to test the Tahiti version because, even if I can make a working binary without, it will probably need to be optimized for the different architecture. I've already seen that tahitii is using more local memory, for some reason, and this may slow down the groestl part a bit.
Funny thing it that I had the card and sold it some months ago :-)
I'm also considering to completely leave djm34 miner version and continue on my own fork because it's much easier to work on the kernel and produces more consistent results.
Let's also see if the interest in the project grows and all this work is worth doing...

Can you create bin for (HD 7790) Bonaire?
Also, hashrate for R270X?

Sorry, I have no reports on that card (and I do not own one).
As soon as I have solved the issues on Tahiti cards, I will create binaries for the other chips as well.

Minimum donation for one bin or some bins?

[pallas]

Minimum donation for one bin or some bins?

From the OP:
Minimum donation for getting the bin: 0.02 BTC

Currently the only official bin is for r9 290 and 290x 64 bit.
There are some experimental bins for 280(x) and 290(x) 32 bit but reported hashrates are too low (could be a problem with the miner, the drivers or the way the bins are generated).
I find it difficult to test bins for cards I do not have, but I'm working on it.
I might release my own miner (sgminer based) later if I can't make the standard miner work and there is enough interest.
