[Fastpow]

Guys,

Everybody agree on that the most reason of Doge success is their community and people.
So,

Our first step is to gather people around this coin,
What do u suggest?
Any idea to get people involve in vertcoin?

Plans are coming soon mate

A word from my side about crashing miner and hardware

Since some days i have a VTX3D R9 290 X-Edition card and there were and are issues with miner crashes and driver recoveries at stock clocks.

BUT: i know why this happens!

1) after i got the card and put it into my win 7 PC this thing was very very hot. even at 700 MHz i had 93°C with Intensity 14. Higher intensity: crash
   -> issue fixed: the original applied heat compound was crap. air gaps inside and some of the chip was not covered. Now with new heat compound it is much better than before.

2) after this heat compound thing i tried higher clock rates.
max stock 975 MHz and Intensity 15: crash after a few seconds. With Intensity 14 crash after <1 minute.
With 900 MHz: really hot but working, even with Intensity 20.
Test with furmark: with 975 MHz and max settings: no problems, works fine for > 5 minutes (just a short test performed)

Then i started HWInfo and checked the Voltages: with Furmark, the GPU voltage is at min somewhere at 0.98xV @ 975MHz.
With vertminer voltage is at 0.94xV @ 900MHz. Also the temps are not as high with furmark @ stock than with vertminer and lower clocks.

-> my conclusion:
for GPU testing purposes, furmark is a toy. If you want to perform real testing, use vertminer. The opencl kicks the GPU to the max and so everything else (regulators, memory) is used extensive.
And if the cards stock voltages are good enough to play games, this does not mean you can use the card with the same clocks for mining.

--> final word
If you encounter crashes, lower your clocks or increase the voltages! And a good cooling is a must!
The latest opencl kernel for the vertminer is even more optimized than the existing cgminer scrypt kernel. You can try to use the latest vertminer kernel also with scrypt cgminer (but needs some changes to work).
I am sure you will see also some sudden crashes when your card is at its limit...

Bufius,

Are you sure the card is OK? I've got Sapphire R9 290s (non-X), the standard reference design (with the hairdryer-like noisy fan).
With the engine @ 947 and mem @ 1500 and Intensity 18 my cards get 76C. Fan runs at 75%.

Higher intensities seem to crash the card at some point, as does a higher clock. Just FYI. I find 93C at 700 wit I14 a bit suspicious.
Edit: Ok, temp was before you fixed the paste problem, but still the crashing is odd. I *can* run the cards at 1000 clock, but they crash after hours/days then. At 85C btw.

Hey,

Just wondering if anyone else has had problems with p2pool?  I just started using it yesterday and was getting payed fine every time a block was found.  Then out of no where no payout for hours and hours even though shares were being accepted and blocks were found.  I only have about 350 kh/s, I don't know if that is the issue or not.

Thanks for any info.

start your own node, fixed all my problems

Thanks.  I will give that a try.

I am sure the card is not really Ok, at least the custom cooler is not the best as it seems.
And the stock BIOS has really low voltages, this is the main cause of the voltage based crashes.
But i will apply again (even thinner) new compound. Perhaps i applied too much.

But the conclusion is the same: the mining application kicks 100% constant load to the card and this is much more than e.g. normal games and even more than furmark (i could not believer this before my own testings).

"You just put some SRAM on die"...
it's cache, it's expensive. transistor count on litecoin ASICs is mostly due to memory. and they are barely in advantage.
double that, and you can not be competitive with gpus anymore.
you not only double the cost of each chip, but also you reduce yield for every wafer.

to be competitive also for next N number it's simply impossible. nobody would want to buy an asic "ready for the next N=12" simply because it would cost twice as much and the market is so volatile nobody know's what will happen.

OF course it's possible to do. but costs are over the sky

It's not that expensive at 55 nm, as the GridSeed ASICs demonstrate.

You don't seem to understand how the TMTO workaround performs: you just regenerate needed values on the fly, and for every amount of memory you halve, you approximately double the amount of intops needed.  This is exactly the same tradeoff as per the GPU, so no matter how much memory you use, the ASIC will always be faster and more power efficient.  There is a slight advantage to using more memory (see below), but it's not huge.



The ASICs themselves don't need more than 64-128 KB of SRAM per circuit to be able to hash much more efficiently than a GPU for any N.

we can do more than just a plan,
it's simple for start, just post how great this coin in everywhere u can.

All you'll end up with is a blockchain that's progressively harder to validate as time goes on, which is actually a bad thing.

Anyone care to comment on this?

This was one of the reasons the N-factor was rescheduled when the hardfork to KGW was released. We wanted to not only keep older GPUs in the game for longer, whilst still maintaining ASIC resistance, but we also wanted to leave open the option of running a full node (ie. a thick client, like the current Vertcoin-Qt) in the mid->far future on "modest" hardware.

As Vertcoin develops, one thing we are sure to see is an Electrum type SPV (simplified payment verification) wallet, in which there is no need for the client to validate the blockchain anyway, because it's done on the server, however philosophically I'm not overly keen on the idea of making this kind of thing something that most people feel the need to use because a full client is memory hungry, I'd rather it was an option but that people could still easily run a full node (to maximise decentralisation).

Yes, on a full node, the blockchain gets harder to validate as N increases, but Moores law and some awareness of history should suggest it is unlikely to be a big deal - it's like we were sat here 20 years ago talking about how by 2000 it will require a whopping 256MB of RAM to run X program, and how could anyone ever imagine having such an amount.

This still doesn't address the fact that it's not any more ASIC resistant than Litecoin...

I've got 16,8VTC on p2p in 24hours with 30min downtime at 2,152Mh/s... P2p rocks, it's more than predicted..it's due to optimized settings so I get 10% less rejects than network, so it's like 10% more payment...Just heads up for everyone struggling with normal pools...I guess results would be even better if I knew how to setup own nod

I like it, specially it's logo with check-mark.

Actually i suggest that check-mark for vertcoin logo.

price is getting lower because of trading bots at cryptsy.

Fuck bots.  And most certainly, fuck Craptsy.

It does seem like they're pushing it lower to hoard, possibly for another huge pump.  In any case, I wish I would have held out longer to scoop up at the $3.50 price point, but I'm still happy getting in at $4.00.  Gotta think medium to long term...we'll all be extremely happy.


In other events, bitcoin and pretty much all alts (except for the ones getting blatantly pumped) are in a free-fall mode right now.  Hope the bleeding stops soon, but the drop to the mid $6xx's doesn't 'feel' good, and I'm certainly apprehensive to buy into any more BTC in the fear it may drop another hundred or so before the big rebound.

[rentarocker]

All in all a good time to sit on the sidelines and just hold VERT.

Yes!    Maybe a check mark with a couple of the currency hashes horizontal or something

It looks really good!

Don't worry, mine and hold, mine and hold. @Vertcoin 's Twitter account now has over 30,000 followers. A few days ago it had 30. This coin is going places and is the main contender for Bitcoin replacement. Long way up to go yet...

I wish I add more BTC to buy VTC now

[svojoe]

The ASICs themselves don't need more than 64-128 KB of SRAM per circuit to be able to hash much more efficiently than a GPU for any N.

Sure, so would FPGA's but at what cost?   I mean really at what cost?  

Gen1 Grid seed and Alpha T will suck at VTC mining,  Yeah they might do it at a better Hash/KWh out of the gate but there is much  more to consider.  Such as re-sale value (in case of crypto-crash) and the premium needed to aquire the ASIC's to start off with.

So, fast forward to Gen 2,  or more preferably Gen 3,  GridSeed.  Its got more ram, Its faster, its 24nm or whatever.   Its pretty sweet for mining VTC by todays standards.  But what about AMD/Nvidia/Intels next chips,  The ones that are still just multi-million dollar computer models at the moment.  Those are getting faster too.

Unless scrypt ASIC rolls out way different than BTC asic in some way.  I don't forecast a point I can forsee where I would rather have some $7,000K Propriety black box to get 30Mhash Scrypt (15Mhash VTC)  When I can buy AMD R11 980X Ultra's for $499 MSRP.  For all we know these future serious cards might hash at 2Mhs scrypt.  

I'm betting my money that GPU's will need to run, One way or another for a *long* time.  Regardless of grid-seed or whomever is doing behind closed doors at the moment.
