Hi to all.
Yesterday I started to mine XMR on my GPUs, they are:
ATI 480 8 gb. Claymore's miner (https://bitcointalk.org/index.php?topic=638915.0)
GTX 970 4 gb. tsiv ccMiner (http://cryptomining-blog.com/wp-content/download/ccminer-1-1-cryptonight.zip)
The problem is that my GPUs aren't so hot, like it was on eth or zec. Furthermore, they are just warm!
My coolers on GTX running 55%, temperature is 52C. Power consumption is 110W instead of 195W at zec/eth.
I thought it's because of old tsiv miner, but my ATI shows the same: temp is 61C, coolers are 62% (instead of 74C/90%). hashrate is 613 h/s on stock freq.
Is it normal?

Usually that means the miners aren't very well optimized so the cards are not utilized completely, causing the low temps.

Absolutely normal. XMR mining consumes less power than ETH or ZEC.
That's a good thing, nothing to worry about :)

Like many algos cryptonight was designed to be difficult to implement on GPUs.
It's only due to the strength of XMR that it's profitable to mine with a GPU
at this time.

That it consumes less power means the GPU is bottlenecked and can't perform at full
power. The low temps mean the cores are spending time idle waiting on data, not really
a good thing.

Optimization opportunities likely don't exist. With the current market there is plenty
of incentive to try but I haven't seen any evidence of a breakthrough yet.

The CPU miner also seems to be topped out. Wolf (included in cpuminer-opt) and Claymore
are pretty close in performance.

Zec was like that also after the dev's tweaked their miner and also optimized its now like eth

Heh, look at this :)

It looks that you are not living on a Florida, aren't you  ;)

Hello, plese can you tell me where i can find this version of sgminer to mine monero?

Thanks.

:) definitely not, central EU.
And one of my 7970's with arctic extreme cooler is operating at 19C,
I won't believe my eyes when I saw that.

Hi,
You can find it in here https://github.com/genesismining/sgminer-gm/releases

Hehe, what is your ambient temp?

Is there an exchange where you can trade hardware errors?

Pretty nice wu/ m too...  ;D

Hello, thanks, i see if only for linux for now.

Well, outside is -3C at the moment, I have half open window, so room ambient is for about 6C.
And believe or not, I didn't "mine" single HW error with those 7970/280x cards.

That image I posted previously is from 470's and it's, because of that I set raw intensity to 500 not 512,
was just testing how it will behave with those settings. I'll switch back to 512.

There is also source code, you can compile by yourself.

295x2/ 295x2 custom cooled, default bios. Ambient 22-25.

where i can find these miner for monero?
is better from claymore?

https://github.com/genesismining/sgminer-gm/releases

you should try it and let us know :)

did you try it is better from claymore?

I think so, with claymore, I was getting constantly low diff shares, and then banned IP.

Nitro 470 8gb.

I can't get these numbers with SGMiner.

How much different in % is XMR more profitable than eth not counting electric costs?

Wait a second, let me do the math for you.
