Changing the hashing algorithm

daimyo

Is there anything special you needed to do to get cgminer working with nvidia?

absolutely nothing… works right outta the box. I am curious to see what a decent desktop nvidia could do

i have a GTX780Ti clocked at 1Ghz i could give a bash?

Anywhere i should get all the files from? Thanks

kris_davison

ive got three 750ti cards in a rig at home I may have a try and get this miner up and running with them.

Wellenreiter

I have one 750Ti and get about 35khash reported by the miner with default settings, just I=10
If I set intensity to a higher value, hw errors increase.
By the way, the pool reports about 24 khash only, but no errors.

Some hashes ‘lost in transit’? ;)

daimyo

Wellenreiter, do we need external help with the stratum? Do you think it would increase productivity?

I can get my 550M to work up to I-13 without HW. -I 12 and -I 13 make little difference tho.

I hate to say it but it seems the 7850 has the edge over 750ti productivty wise while at same price… :( Tho I am not sure if lizhi had aggressive overclock or its just too hot in China :D - 86C

What temps are you getting with the 750ti ? Have you tried I-13 ?

lizhi

I gave it a try last night on my nVidia 550M, Win7 and I got max 8 khs. Mostly default settings, --worksize 256 -I 13, no overclock. Driver version 294.10 - a bit old

76C gpu temp -> not bad

I think it can reach up to 10 khs with some tweakin

This is what i get with -I 14

Limitation of the gpu?

And whats the logic 7850 to perform 3 times faster than 7970?

Do you guys expect the stratum implementation to raise the productivity significantly?

cgminer say “Maximun buffer memory device 0 supports says 536870912”

Please reduce the thread-concurrency

kris_davison

750ti are less power hungry tho?

Flobdeth

does -g 3 -I 17 work, or throwing back HW errors, anyone tried those settings?

lizhi

does -g 3 -I 17 work, or throwing back HW errors, anyone tried those settings?

-g 1 -I 13

daimyo

-g 2, 3 crashes the miner here

lizhi, you are correct. High tread concurrency was the cause

Help with stratum would be really appreciated. My actual code is on github: https://github.com/wellenreiter01/p2pool-neoscrypt

I can add anybody to the repository who want to help.

I tested with minerd from Ghostlander and the hash calculated by the pool is always 2 byte too long when using stratum. Longpoll works fine.

Didn’t check my GPU temp, as the fans are running low speed it can’t be too high.

The NVIDIA cards are slower than the AMD card with opencl based miners.

I hope for Cudaminer to be adapted.

That should boost the performance of the cards.

AmDD

You all keep mentioning Nvidia cards. Is neo better run on those or is AMD still dominant? I ask because I have 3 rigs full of 7950’s that Im holding off on selling to mine feather once the algo is changed. :)

I want to setup one on the test pool this weekend if I have time.

kris_davison

The openCl gpu miner seems to run better on nvidia cards but if/when there is a cudaminer (nvidia specific) they should be pretty even. Nvidia cards generally use less power and are not as hot but you don’t get as high a hashrate so its swings and roundabouts really.

daimyo

folks, check this out https://github.com/ahmedbodi/stratum-mining-multialgo it claims to support stratum for neoscrypt

Wellenreiter

unfortunately this can’t be adapted easily to p2pool.

Edosterman

Where is the source for this. Love to help.

I have a bunch of GPS’s i can throw at this.

Edosterman

that would be GPUs not GPSs

sigh

Edosterman

folks, check this out https://github.com/ahmedbodi/stratum-mining-multialgo it claims to support stratum for neoscrypt

this has not been modified in months

only looks like cpu neoscyrpt at best.

other cpu miners available if wanted .

lizhi

I had pushed it in http://www.ftc-c.com/pack/testnet.rar

please download it ,test it

lizhi

My p2pool is running normally. >:D That is not too many connections .

There are 3 connections in wallet, 1 miner connect p2pool.
