[ANN] QQCoin- Scrypt Jane, ASIC Resistant, N-Factor, Multipool Resistant

[lenovothinkpad]

The price is crazy low now, especially considering most of the coins are mined out, so there's very little inflation.
On a side note, I joined the QQ groups a while ago and everyone thought I was a Japanese girl for some reason. LOL I'm an American man.

so, price not crazy , and you are crazy japa girl 

[Litvin]

Well, the news I heard is that by the weekend this coin is going to increase heavily. Some big whales almost finished stocking up on it. It is harder to mine now.

Hopefully we will see 1 dollar qqcoin.
I am still buying into this coin whatever I mine until then.

I also believe in it. All Mining single coin QQcoin not sold!

Are we at NFactor 11 now or something? Only getting 115-120kh on my 7950 right now.

Yes, we are at n-factor of 11. 7950 at 115-120 kh/sec is a good speed. The maximum you can get with R9 290 is 129 kh/sec with no hardware errors.

What we need is a linux gpu miner for this. I'd love to be able to mine this coin!

Cool，QQ is the most  popular chat tool in China .

[haggis]

Hey yonghongtang,

thanks for all your effort. Will send some coins after wallet has synced.
I have problems to find the QQ groups. Are they on qq.com? Is there any login/register button? I had hard times navigating through that google translated site
Thank you!

QQ is the most  popular chat tool in China . like former ICQ, MSN.
download here http://www.imqq.com/?lang=1033
install , and run , you will find register button. then register , login , use it to find our QQ group.
you can send me PM if there is a problem.

Thanks! Unfortunately there's no linux version available

Yacminer 3.4.2 is the best miner for this. Release by Thirtybird.

Go go qqcoin, chinese are expecting you.

Only a little while before people are hit with the fact that scrypt-jane is asic proof.

[haggis]

I tried it with the latest code of Thirtybird. (https://github.com/Thirtybird/YACMiner/releases)

While the latest release ends up with an error within "make" (yacminer.c undefined reference to `max`) I can clone the repository and compile that.
However, the results are not looking very promising:

Code:

./yacminer -o 127.0.0.1:20112 -u haggis.qqc -p x --nfmin 4 --nfmax 30 --starttime 1387769316
[2014-02-27 13:18:45] ./yacminer: --nfmin: unrecognized option

This is the hottest advice so far

I got the patch applied and source compiled. But I get only hardware errors with this:

Code:

export DISPLAY=:0
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100

./cgminer -o 127.0.0.1:20112 -u haggis.qqc -p x --scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1387769316

I can't believe people went nuts over vertcoin becuase it has an "Adaptive N-Factor" and is ASIC resistant. Scrypt-Jane has an adaptive N-factor, and a bunch of different hashing functions, and is way more ASIC-resistant than vertcoin will ever be.

Are you sure you are using the latest version 3.4.2 ? ? The previous 3.4.0 certainly is not supporting nfmin and nfmax parameters, i don't know about 3.4.1

Try again with 3.4.2 if you're not using that one.

Just use --scrypt

[lemfuture]

if auroracoin can do it, we can do it! 

[haggis]

Thanks for all your responses regarding linux mining!

I finally got Thirtybirds build compiled (with his help) and now just need to get rid of the HW errors. Seems like scrypt-jane is much harder to configure than scrypt.

https://github.com/Thirtybird/YACMiner/issues/4

[haggis]

Hm, I'm now fiddeling with the YACminer settings for hours and still didn't get at least one accepted share - only HW errors.

The README says the following settings are important:

- rawintensity
- thread-concurrency
- lookup-gap

The formular for the OpenCL Buffer allocated per thread is:
MB per thread = thread-concurrency * 128 / (1024 * lookup-gap)

My R9 290 has 4096MB, so the optimal values should be:
TC: 65536
LG: 2

But then the card is DEAD right from the beginning. Since this might just be a performance optimization, I go for now with TC=16384 and LG=4.


Further, the rawintensity seems to be important to avoid HW errors.

Code:

Valid values for raw-intensity need to be in multiples of --worksize.  Cards in the 
R7 and R9 family may allow for adjustment in smaller increments - the lowest found 
has been adjustment in multiples of 8.  The following is a guideline on where to 
start with your card and will most likely not be the exact numbers you end up with.

Memory	# of shaders	LG	Raw Intensity
1GB	Low Shaders	4	Shaders*4
2GB	Low Shaders	2	Shaders*2
2GB	Low Shaders	4	Shaders*8
1GB	High Shaders	8	Shaders*1
2GB	High Shaders	4	Shaders*2

Adjust Raw Intensity up and/or down until you no longer receive HW errors in the GUI.

The R9 290 has 2560 shaders. Lookup-Gap is 4, so I start with a rawintensity of 5120 and went down to 128 in steps of my worksize (128). But nothing. It only influences the speed of the HW errors coming in.  

Scrypt-Jane is kind of rocket science. Please help! What are your settings for GPU mining this?

[lumberinvestments]

These are two settings I use for the R9 290 and working at n-factor of 11:

1st Computer with R9 290
-------------------------------------------------
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
yacminer -o x.x.x.x:20112 -u lumberinvestments -p qdwq2133s --scrypt --nfmin 4 --nfmax 30 --starttime 1387769316 --lookup-gap 2 --thread-concurrency 28600 -w 128 -R 6528 -g 1 --expiry 10 --gpu-engine 1070 --gpu-memclock 1500 --gpu-powertune 20,20 --auto-fan --scan-time 1
---------------------------------------------------

Second computer with R9 290 GPU 0 and R9 270x with 4 gigs of memory as GPU 1
-------------------------------------------------
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
yacminer -o x.x.x.x:20112 -u lumberinvestments -p lsdq22oos --scrypt --nfmin 4 --nfmax 30 --starttime 1387769316 --lookup-gap 3,2 --thread-concurrency 42000,28600 -w 128 -R 9728,10240 -g 1 --auto-fan --scan-time 1 --expiry 10 --gpu-engine 1070 --gpu-powertune 20
-------------------------------------------------

In this second computer I get almost 130 kh/sec with no HW for the R9 290 and almost 90 kh/sec for the 4 Gb R9 270x
You can see that the hashing speed differences between the cards start to get lower as the n-factor goes up.
In no way in windows you will be able to access all 4 Gb of the card, just download HWinfo and use it, look at the dedicated and dynamic memory of the videocard.
The higher the lookup-gap the higher thread concurrency you can go. Beware that there is a point when you increase the raw intensity and your hashrate will drop dramatically. That is the sweet spot. First you set up lookup-gap and thread concurrency until you can't go up anymore with thread concurrency. Have a low raw intensity. Then you increase it slowly and you will see your hashrate increasing, but stop when you will see the HW or sudden drop in hashrate.

Everything depends on your other configuration, like system RAM. If you have too little, you will not be able to go so high TC. I use 4 GB of system Ram and I assume I might be able to get higher if I put 8 GB total.

If this has been proven useful then you can donate to me some QQC and I will donate further share to Thirtybird

Here is my QQC address: QhACLXR1SbQu354aVJWf5EYYS8dPfFgVKN
We need to raise QQC to the sky by increasing the hashrate !
Have a nice day !
