Another attack? XD

Time for some cloudflare.

can you share your settings and system config?
Mine does not do more than 630mh @136w (76% TDP) 65C 70% Fan
System: 6x 1080s gaming x G1820 16gb ddr3 ram

i've network issues since 3/4 hours. Trying to understand whats going on

yeah yiimp is delivering soem problem again for me too, not only skein but bitcore and x17, seems another provider issue? or another ddos, i hope it can be fixed asap, there are not many option to mine skein and x17

You should be getting +30% compared to a 1070 with a 1080 and +85% compared to a 1070 with a 1080ti according to cuda counts and pricing. If you're getting 60-70% more then a 1070 with a 1080 you have something misconfigured with your 1070 as it's underperforming. A 1080 and 1080ti will underperform compared to a 1070, but not the opposite direction unless you have something setup wrong. GDDR5 is quite mature, algos have problems with GDDR5X.

As far as what algos are having problems, you've quoted someone of them. I'm not going to tell you about them though.


I never said there weren't coins doing that, I was laughing at you being unable to talk about them because you know they'll get hammered if you do. Remember when I mentioned the 277,000 1070s mining Equihash? Yeah. You have to be a pretty big dumbass if you don't realize what that'll do to any coin you mention, completely taking out of context the whole discussion was about how you can mine mainstream coins with AMD and Nvidia is all niche stuff if you want to make any sort money (which gets hammered immediately) and even then AMD still ends up well off ahead with their mainstream coins.


What? That's common bogus developer rhetoric. GDDR5X is broken for about half the algos. It needs to be fixed. It's not a feature until it actually does something remotely beneficial. And no it's not a 'oh it's latency and it's broken 4evarrrr' thing, algos need to be tuned to it.

What's up with yiimp skein? Been down for ~ 30 min. Is there any way to specify a failover pool in ccminer?

Why are you talking 'bout skein? )) You were laughing at me when I told you 'bout $10 per gtx1070 some time ago ))

These are not issues, but "GDDR5X features"
bandwidth is up, but latency/access for smaller chunks is not, thus algos that do not depend on bandwidth (skein), or can use memory in fully cached chunks scale with cores.
Algos which are critical with latency or non-cached memory access doesn't scale well

On joincoin, after the fix, you could run multiple wallets just by using different conf files with different ports (rpc and p2p); plus you need one "master" tor wallet, and the others who point to it via the -tor option.
Both verge and digibyte probably don't even need the fix.
I think the issue is with coin confusion somewhere in the yiimp code.

Can you add blake2s/verge and myr-gr/digibyte to yiimp please?

Pallas did a fix in the joincoin wallet to be able to mine to Multiple wallets per machine, perhaps a similar fix can be done in the Verge/digibyte wallets?.

Multiple wallets per machine fix
Fix initialisation hanging on remote tor usage.

why "half the algo", i only have bad result on ETH and feathercoin, all other algo i'm doing 60-70% more versus a 1070, with my 1080ti and 80-90% on skein/jha

GDDR5X GPUs still have issues with compatibility. A 1080 for instance will sometimes get the full 30% speed increase over a 1070, but often times it wont. About half the algos worth mining right now have problems with GDDR5X. You'll get anywhere from 10%-30% (usually around 15%). A 1080ti is no different. It's a shitshow, skein doesn't have problems.

which clocks and miner , do you reach 740MH/s with Gamerock. Mine give about 700 on 80% tdp...

palit gtx 1080 founder edition 700mhs skein @ 140 watt (80%tdp). 5mhs/watt, 62 degrees C with 100% fan.
palit gtx 1080 gamerock        740mhs skein @ 165 watt, 4.4 mhs/watt, 58 degrees C with 75% fan

yeah 2 x 1070 look better, but i need density now i have no more room, and i only have the option to add another gpu, so the smart move is to buy the faster one

still on skein 550MH of a single 1070 versus 1G of a 1080ti, is a very good compromise, 80% faster...

also do people really care about the price of a gpu at the moment? when everything is roing in two months? i don't care much about that, it's also funny because my last rig roid in a week or so...and i'm not joking i just hit some good profitable coin

p.s. i have noticed that the 1080ti is bad on some algo, like neoscrypt, can this be improved, or it's because of the gddr5x?

unfortunately that's best end-user price available.... buying from other country will be cheaper but will bring warranty and resale problems

2x 1070 (and you can find better prices)

skein is just about cuda cores, that hashrate is normal: 1080Ti has 40% more cores than 1080, which in turn has 33% more cores than 1070, IIRC.

can someone explain how 1080Ti is making 1GH/s on skein, but 1080 only 660MH ? Just using different miners?

Can someone help me to compare 1060-3gb / 1060-6gb / 1070 / 1080 ?
A friend who wants to start mining "for fun" wants to buy few cards , I think he won't pay more than 900-1000e for the "mining" system, and asked for advice (he wants NV)
And as I use AMD (not counting 2 750s) I fail to find detailed comparison

Am I right to assume these numbers more or less correct:

Thus I think 1060 3Gb or 1070 are better  bang for buck IF we talk about limited number of cards to use, not about power-density-per-rig? Similar ROI, they are better in dagger-hashimoto and equihash per-$, also should lose less value 5 wise
Does these calculations seem ok?
For reference, approximate prices here (in euro)
1060 3gb - 240e
1060 6gb - 290e
1070 -  420e
1080 - 550e

I think he'll be better with 2x1070 or 3-4x1060 3gb?
Thanks in advance

Please, maybe somebody can help to compile the code correctly? I'm on Ubunty 17.10 with Cuda 8.0
I'm already compile the code from git repository linux and from main branch with the same error results:


When I compile the code I add "-fPIC" to nvcc to compile that, because without that it was the problem to link .o files.

How to recompile that to get to work?... Thanks...
