Hello, I just found out, what is going on?, did anyone see this post?: http://www.simplemulti.com/news

profitability in http://www.whattomine.com/ went down far below X11, what happened?.

Quoted from Reddit...

"It is a problem with the pool implementation, the algo is fine.
Lyra2RE has a different share difficulty than scrypt-n, you've probably noticed your miner (correctly) submitting fractional shares, whereas scrypt-n utilized integers. But since Lyra2re uses a different share difficulty, the code that rejects low diff shares has to be modified as well.
Its completely our fault for not realizing this needed to be changed, but I'm guessing this part wasn't included in the stratum mining code, and that is why it is an issue for several other pools.
The effect of this was that most low difficulty shares would be incorrectly accepted as valid ones, which causes pools to calculate & display the hashrate far higher than it actually is.
I feel I should point out that there are very few miners who would 'accidentally' benefit from this. Because it requires your miner to not only submit its low diff shares (the default is to dump them), but also have a large number of low diff shares to start with. Normally doing these two things will get you quickly banned from a pool, because you're effectively spamming invalid shares."

Thank you jamesl22, crystal clear, nothing wrong with the algo, good to hear that

Has anyone successfully got a local p2pool working?  Below is what I am getting.  I did have a problem with miner in Linux, but I got that all worked out.

Thanks

Here is how I am starting up p2pool.

James and vert devs

Is coinme by vertpunk online wallet still functioning? I have been trying to contact its support for days but not getting any response.. can you help? I have 2 incoming transactions missing..happened right after the fork..

[HashEngineering]

Is there a need in updating the Android Wallet for the fork?

[voephilis]

okay guys.

seems we have reached the bottom on about 9k.

how much hashrate do we have all together?

[ocminer]

okay guys.

Not one miner left on suprnova, but according to the wallet we have about 3GH/s in nethash...

[cnerd]

So, tell me one more time, why are you not switching Monocle/ZeroVert to Lyra2?
The idea of the merged mining was to decentralize mining by giving incentive to p2pool mining (yea, I know that didnt go exactly as planned).
Now we have nothing to merge mine, Monocle is getting de-listed from the ONLY exchange that offered it and it seems that nobody, except bengtåke, gives a fuck about it.
It was somehow obvious that Monocle will be abandoned as soon as ZeroVert appeared, but now it seems that the latter was also neglected.
Whats up?

[tankist0]

committed, I changed the integer type for the target and forgot about it... sorry about that.
should work now

here the windows binaries with latest version: http://ge.tt/5zIW3972/v/0?c

Thank you djm34! I've got some increase, but the most interesting part - take a look at WU!

280x hynix, 815/1500 -g 2 -X 256 -w 64 -no-submit-stale
drivers 13.12 (so I can lower clocks) + 14.6 bins

What hashrate should I expect on Nvidia 780 and how much power does it consume?

[djm34]

What hashrate should I expect on Nvidia 780 and how much power does it consume?

don't know... I have a 780ti (OC) and it does ~1600kh/s power consumption is around70%

are you serious ? that is a lot on a single card! I mean hash horse power congrats!

yeah so that is ~ 519$ on egg .. let me see .. 750 ~140$ I think at 620 kh/s (no oc ) yeah so one needs 2.5 x 750 ti to have one 780 ti...  so thats like 350$ .. but still.. only single PCI so you can pack more.. very nice regardless congrats again on the choice, smart

let me see amp needed (Watts) on 780 ... reason I went with 750 like a year ago.. is electricity.. really adds up.. over time

I ment kh/s above of course mh/s would haha be awesome.. but in my dreams  

also thinking to undervolt and overvolt thru BIOS.. a dont want to destabilize the system one really has to know what one is doing with Linux..

yeah so 250 W on the 780.. so in my case I would pack two of them for 3 x 750 (hash power wise) but would need to bump my power supply no big deal but maybe this post here helps someone building a rig or planning for one  

spec on 780

http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-780/specifications

spec on 750:

http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-750/specifications

what is really nice with 780 is for extra dollars (power supply) cooling system cost wont increase as seems temperature spec is the same for both cards that despite > 2 x as many CUDA cores! great achievement by Nvidia.. here

anyways have a great time mining dont worry too much because of VERT price.. everyone is in the same boat and just be patient

djm34 question, at that speed, how many watts at the wall does that little beast eats? I will really love to know.

I am about to build some more rigs and will love to know, so far the winner is 750ti, but a 1600Kh on a single card is tempting! but power consumption is the most important thing

the 780ti is rated 250W so 70% of that is 175W
a 750ti is rated 60W at 55% that's 33W by 3 ~100W (people with watt-meter should confirm though)

It means stay away from the 780ti   (and I am a big fan of the 780ti...)

prices might go down on GPU cards in general although people said that couple of times this year and nothing.. that is because of us miners! we are the demand and keep prices where they are

aha!, the difference seems to be huge, but i trust more on power meters than computers

780ti it is rated at 250W but it doesn't mean that is what really eats , a lot depend on the algo used, if anyone here has a 780ti and a power meter (kill-a-watt like) plz post results.

I have 5 x 750 Ti (3000 KH total) and using 250 W, which means 45W x 5 + 25W mobo = 250W and that is at the wall, meaning, i didn't take into account power supply losses (80 plus bronze at 30% load) that of course is in lyra2, X11 power go up to 320W total, and scrypt-n was about 440W.

still... it was a long walk from the previous year when we where dealing with over 1000W per rig!, insane!.

@TheCoinFinder others , anyone knows why on pool https://pool.verters.com block time find has extended to over one hour ?

thanks

update... back .. it was just this one block.. believe back on track , hopefully

must have been really really bad luck

[joyyen]

hi if anyone tell me this works on ATI 5850 ?

i cannot get this works on my ATI 5850 !

it's working..
300khs..

Hi help i am using windows 7 32bit 4gb ram 5x sapphire 5850s

Driver 14.4

i have download the AMT/ATI x86 sgminer but i cannot get the miner to works ! anyone please help me i will give some tips !

Done found out the problem !

Yes, it happens. Same as sometimes we get two blocks within a minute or so.

yeah no problem at all, since its a new algo its just being cautious, thanks for running your pool btw

"bad luck" blocks must be causing havoc in the multipools ops as they don't know if it is caused by high difficulty or bad luck  

it is great to see ASICs and fpga's taken out of equation. LTCGear must have some unhappy customers (LTCGear share farm explicitly targeted Scrypt-N and contracts are not short either, I am always worry about shared pools because of exactly what just happened.. with VERT shifting to lyra2)

so far so good had 2 SIGINT exceptions.. btw another tip if on Unix use supervisord so the mining software restarts automatically on critical faults
