I recorded the play-by-play for you guys.
GeForce GTX 1080 Ti Founders Edition 11GB GDDR5X Unboxing and Setup Part 1: https://youtu.be/uR7UmKSJ35M 
Part 2: https://youtu.be/BOzKsTZVhrg

More to come =)


Impossible to see the hashrates..  Roll Eyes
750 oc in zcash, 710 oc with 90% tdp according to the video.
I can do 600h/s on a GTX 1080 oc (evga hybrid : gpu@2075, mem @ 5500), 540 on a founders edition with some oc (but fan @60%, with gpu around 1850mhz due to temperature)

Wow.

...

What a drop. Stress-test before shooting to ATH?
The same drop for eth/ dash ... not monero specific
some news on btc ? the btc price drop ?
103  Alternate cryptocurrencies / Mining (Altcoins) / Re: GTX 1080 hashes? on: March 17, 2017, 08:43:31 AM
What does a 1080 pull on DCR, LBRY, Lyra2re2, and Equihash (on NiceHash) while on 50% TDP and full power, with OC?

I am running into old results with outdated miners when looking these up or incomplete settings info



50% TDP is not the same for the various models/ brands... Difficult to compare.
On http://yiimp.ccminer.org/bench?algo=all&chip=21, you will have a comprehensive list of hashrates with power usage (estimated via the driver: not power wall mesure).

Where is normal pools for XZC?

Now i mine xzc.suprnova.cc but get little coins.

My hash - 4250 kH/s

Whattomine
4250 kH/s -> 2.202512 XZC/Day

But real on xzc.suprnova.cc
4250 kH/s -> 1.3 XZC/Day  (REAL Pool Efficiency 60%)

And ?
Whattomine write what they want, they are not official... and they prefer to write bullshit to make sensations.
Everybody know that.


Ok. Let's calculate manual.

Pool Hash: 5691.03 MH/s (from xzc.suprnova.cc)
My Hash: 4.25 MH/s
Block rewards: 40XZC
Est. Avg. Time per Round (Pool)   19 minutes 55 seconds   (from xzc.suprnova.cc)


The percentage of my participation = 4.25/5691.03=0.00747689 (0,747689% wy work)

Total Blocks per day on pool = 24*60/(19+55/60)=72,301255
Total XZC on pool per day = 72,301255 * 40 = 2892,0502 XZC

My XZC = 2892,0502 * 0.00747689 = 2.1597  XZC/Day

Whattomine
4250 kH/s -> 2.190921 XZC/Day

But real on xzc.suprnova.cc
4250 kH/s -> 1.3 XZC/Day  (REAL Pool Efficiency 60%)

xzc.suprnova.cc is BULLSHIT!!! Not whattomine!!!
You cant trust Whattomine or other.
On suprnova you can check all stats by all blocks what you mining.
And lust week difficulty geting up to 40-50k.
You can calculate and get calculate only at big period of time and if average difficulty will be stable +-10% but not +-100% like now.
And suprnova is best because you can see all stats.


But he is right, there is something definitely wrong, it is maybe the miner I dont know, but the profits are really 60% (maybe even 50%) compared to calculations. Ive tested this on two rigs for three days.
Maybe there are some miners who may have found some exploit to submit fake shares  and are stealing from other miners ? This has happened in the past for some coins...

Anyone have result with Ryzen and Hexxcoin ?  Smiley .
I think it would be nice if some could compile new version incl. new ryzen cpu. I am trying to get it to work, but somehow ryzen is not so good as intel cpus for mining.
...
Hello,
Could you try with 4 threads, with affinity setted by task managers on physicals cores, two by CCX. You may try with HT disabled.
For many algo, max performance is obtained with a good choice of threads different than max number of virtual cores/physical cores.

On my 6900k@4ghz with DDR3200, I could reach around 1900 around 4-6 threads.
With a xeon 2696V3 (18 cores) max on hexxcoin is 3200 with 7 cores and some kind of turbo boost hack and bclk @140hz: 3,3-3.950 ghz (and HT disabled to have higher turbo boost).

Lyra2z330 shouldn't drop in performance with too many threads the way cryptonight does. It should remain relatively steady once
it reaches it's peak.

As for compiling for Ryzen there are 2 points: compilers would first need to be updated with support for Ryzen and Ryzen contains
no new technology, it's just catching up to Intel with AVX2 (still not clear on their implementation) and hyperthreading so there's
no need for special compilation.

As with many AMD architectures compiling for native architecture is probably not the best choice, core-aes-avx2 is probably best.
This is note what I observed with my tests (maybe because I have cpu with large cache).
With the 6900k and the xeon E5 2696V3 (= 2699V3), it seems there is a sweet spot probably related to cache size and to the memory bandwith available which can increase with threads till some optimal value (4? I suppose with quad channel): 4-6 for the 6900k (20M cache) 7 for the xeon (45m of cache, there is some turbo boost effect for the xeon with fewer threads, but the 6900k was oc @4ghz for all cores).

onecoin.eu is a REAL and not fake coin like this one, it has a blockchain and everything,
it has over 3 million users who currently have OneCoin's as well.


The only difference is the blockchain is private and not public, and the coin can't be traded until it will be released to public next year on 2018.
...
the coin here like all the rest of fake "1coins" will go up and fall big later.


but the real OneCoin, with 3 million user base, Will be the next big thing!

If you want to learn about the real Onecoin and have real Onecoins you can always send me a message

what is it?? And where did you get this ??

extract : "With 120 billion minable coins and a centralized model, OneCoin can..."

Well this is centralized coin: like ripple for instance, or like amazon coins or any tokens from various corp...

One of the main point of crypto coin is the potential decentralisation... Not for this onelife onecoin which is just a private token/currency for a circle of users/corps.

This project looks like a very unfortunate joke, it is because of the abundance of such garbage projects that many still do not take the cryptocurrencies seriously.

There is something strange for a joke : blockexplorer, pool, exchange, cpu miner, gpu miner (even one from nicehash) have been added very quickly and works fine,  wallet works perfectly with a new algo (albeit simple algo but with pow and pos)better than many "more" serious projects with pretty roadmap ...

This looks like more a tentative bet on opensource power rather than a joke.

Is there an altcoin that can still be mined with a home pc and give something back?

I would like to try mining just to see the process so that I can understand it better.

With the cpu : xmr (use claymore miner or xmr-stack)
With gpu (not too old : less than 4 years) it will depends on you gpu.
A good start for gpu mining is nvidia pascal or maxwell ( GTX 10xx or GTX 9xx, pascal is better in general), or amd RX480 or fury. Old amd cards like R9 390 or 290 and even 280X or hd7970 are good too but more heavy on the power usage. Gpu mining concern usually XMR, ETH, ZEC (claymore miner for amd, others for nvidia).

To begin you main mine at nicehash pool (you may even use nicehash miner) to gain directly btc.

Anyone with this issue ? .
I suppose the first one is driving the display ? Is there some soft running using the video card : chrome or other browser?

Huh? What? You can also just use the miner for yourself, it's not bound to the pool. No one released a miner yet, so what's so bad about it?

I will never connect to your pool since you are a thief

Ocminer is a respected member of this community and I personally never have had any complaints when using Suprnova.

So maybe you should not be throwing around baseless accusations.

575 sols
25% more efficient for an added cost of  50%.

A good xeon V3/V4 could have earned a lot the first days of zcash mining, when amd/nvidia gpu had lower performance than a high end cpu... (50h/s on a 5960x against 20h/s on the GTX 1080 with the first nicehash cuda miner).
You may buy a QS/ES version on ebay for a reasonable price.

Sorry but this doesen't make sense at all.

1) CPU mining it's totally useless in the crypto scene: density (1 CPU vs 7 VGAs), control (configure them in a VGA farm, good luck), availability (ES, really?), benefits (Not a single one. If you put an heavy load on the CPU, you'll cripple the VGAs performance)

2) High end CPUs are useless in opposition to cheap - decent - ones, due the total absence of a CPU bottleneck in the mining process (Bandwidth)

Bullshit³³ you have no idea but it's okay but stop talking about something you have no idea about instead of giving you bla bla

It would be optimal if you would report your direct experience and gains (cpu vs gpu in the same system, at the same time), because the only one making claims about high end cpu benefits, it's just you Wink. No offense, but I prefer to talk by considering facts. Proove your statements, sir.

Zcash was better the first day for cpu miners, and so was zcoin. Everyone has a cpu, many more than they need or only need
occasionally, but not as many have a GPU, ever fewer a big GPU or multiple GPUs. Buying a full PC just to CPU mine is a waste
of money but if a cpu is already there, it might as well be put to use. It's similar to gamers, they already have the gpu power so they
should all be mining when not gaming.

With the state of GPU mining right now your not standing on very firm ground.
dga (a talented dev) has a lot of profits with cpu mining monero at the beginning: he rented amazon aws:
https://da-data.blogspot.fr/2014/08/minting-money-with-monero-and-cpu.html
There are some coins dedicated to cpu mining (riecoin, xmg ...).

Cpu mining is still interesting for xmr and some rare case. I don't talk about making a cpu farms like gpu farms but for someone with home/office rigs, you will take advantage of the high end cpu for your regular use and can pay back the cpu with mining.
On ebay you can have a used xeon E5 V3 or V4, ES or QS at a very reasonable price (400-1200 $) which will give you xmr hashrate between 600-1000 h/s.
You add gpu and you have a powerfull workstation capable of mining as well as gaming/video/computing/...

[R9 FURY speeds]

about 400H/s from sinlge grphic card, is it normal? Quite insanse. Double lower than polaris.

Yeah I get less than 500 with my fury on claymore.  use another xmr miner, you'll get around 800.  But its mining Zec anyway.  I havent played with it for xmr, but i'm quite positive it can do more.  I wonder if w0lf has a fury.  There are private miners out there too.
I got 880h/s with a fury-x gpu@1125mhz with claymore 9.6. Try with -h 1024. Driver between 15.12 and 16.11

I never use cheap CPU..never.
My miners are either Xeon Hexa Core or i7 Quad.
My next baby will be Kaby-Lake and Skylake-EP :-D X299 FTW.

Rephrase what I always noticed and see in this forum: Who buys cheap buys twice! Or cry because weak cpu is not capable of running the miner. Pfff tired of this.

.. no offense but an expensive cpu for mining purposes it's useless.

Plenty of experience in matter Wink.

If you need to use these machinery for something else ok then, but don't generalize.

You may buy a QS/ES version on ebay for a reasonable price.

Are we talking about CPU mining or the CPU to support GPU mining? Xeon is waaaaay overkill for GPU mining.
In some way both : the point is having a strong processor may help for gpu mining when miners are not optimized like opencl for nvidia, or event the first opencl zcash miners and, by the way you can use the processor for cpu mining.
Typically with a many core xeon/ i7 (> 4 core) you may dedicate one or two core for the gpu miners if needed and use the others for cpu mining like xmr for instance. This is the point of view of a "home" miner with one or two rigs, who use his rigs for personal tasks too.
For a gpu farm, this is very different I think.

120  Alternate cryptocurrencies / Mining (Altcoins) / Re: Nvidia gtx 1080 vs 1070 - effectivity at mining on: January 29, 2017, 04:04:16 PM
Hi guys

You agree that the majority of this community claims the 1080 not to be very effective at mining, because the potential of this gpu cannot be fully exploited.

Bet let's consider this scenario in these days:
- 1070 costs about 420 EUR - with no oc you get 400 sols, with oc 440 - power consumption 150 W
- 1080 about 630 EUR  - you get 580 sols - power consumption 180 W

In fact, it isn't much worse than the 1070.. and you got better density, same or better effectivity / watt, less money for the risers etc.

Isn't the 1080 worth reconsidering ?

Thank you



I depends on the price : In France, there were some GTX 1080 around 500 euros in January: at this price it is a good buy. At 630, I would prefer the GTX1070 for 420.
