Guys, I m noooob miner,  I was wondering if I mine (cudaminer)  with 2 PC on a 3rd PC's wallet  (all pc on same lan ) the hashrate is going to be what excepted  pc 1 hashrate + pc2 hashrate or I m missunderstand something ? Do I need 2 wallets? 

Thanks

I'm guessing you're talking about solo mining, in which case you use the LAN IP adress and such for the set-up, instead of local-host, as far as I know. As for two wallets, one for each, that is recomended, because if the computer with the wallet goes down for any reason, you can't mine. A wallet for each rig would be more redundant and reliable, and you could just wire the cash to the central wallet when you feel like it. For external acces to the rig without having to put a screen and K&B on it, use programs like teamviewer.

Thanks! yes, I forgot to write that i try to solo mining :-) . I still have concerns about hashrate being rig1+rig2, because I dont know with what logic Cudaminer generate hashes , maybe 2 istances of cudaminer 1 on each rig generate the same hashes ? I know this is the basic of mining for you guys, but I dont know where to find such informations.

I am no solo miner, but I'm gonna tel what I'm thinking, and if I am wrong, we will know soon enough.

You set up your miner and point it towards the wallet. Your miner starts working on the block, working just as long till it gets a valid outcome, or if the block gets solved by someone else. If you use multiple rigs, and this is the point which gets me doubting myself, they start working on the same block, and whichever gets it first gets the valid message and the cash. This is comparable with needing to roll at least one six on a dice to win, but now you're rolling with two dices. The other option is that they work at different blocks, but it still doubles your chances.

As for the hashrate, provided you get each card at 99-100 utilization, you get your max hashrate. If you do not reach that, you can try running two instances on the same card to get max utilization, which would again use the first example I just said, but now on one rig.

Again, I am not sure, can someone confirm or disprove this for me?

Ok let me jump in  

so each miner when solo mining will be trying to crack a block. it doesn't specifically try and crack a single block, it generates hash's at random, until it finds enough to generate one full block.
this means that each mining instance will be hashing away, it does not mean that they work on the same block, it means their both trying to figure out blocks.

lets give a simple example.

Rig 1 - 300khash/s
Rig 2 - 200khash/s

point them both at the same wallet, and that wallet has the equivalent of 500khash/s being sent at it. in theory every hash that is done adds together to try and make a block.
when mining you put in an ip address for the miner, these should both be the same on each miner.

you do NOT need 3 computers to mine, as the wallet can run on one of the mining systems.
in short, pointing 2 miners at 1 wallet adds up the chances of you finding a block.

similar to what DemosMirak said,
if you have a dice and you want to role a 6, and one computer roles 300 times (300khash/s) and the other roles 200 times (200khash/s) you role a total of 500 times (500khash/s) as they are working together (mining to the same wallet)

any more questions? i know its been dumbed down a lot but it should be easy to understand

Ok thank you and thanks to DemosMirak for your answer!! Now I know how to do stuff right :-)
No more question

You failed to understand how mining works. The hashes you get which dont solve a block, dont "build up" a block at all. Some hashes are just "lucky" enough to solve one.
Mining has no memory effect, its completely "random".
It does not matter if you put 200kHs and 300kHs at the same *coind or different one.

Please stop spreading misinformations as it confuses newbies believing this which therefore hurts the future newbies.

There are enough Threads/Posts which explain why it dosnt add up!

[bigjme]

Ok no more info from me.  

By the way that is NOT what i meant atall and is the way you read it. By adds up i meant combined effort.
But never mind, if i am going to be insulted with a snappy reply i wont be helping anyone again

On the latest nvidia driver for linux 337.12.  with cuda 6

Unfortunately i cant tell what options are in the nvidia-settings as my monitor is plugged into the intel video.

From the cli tho everything looks fine.  ccminer works well, i think there is a slight increase, but could be placebo.

craigdabbs, are you sure that overclocking with latest beta drivers had any effect?
i ask because i've tried some values (100, 300; 200, 500) on my gtx660 but i can't notice any improvements...
what's the output of nvidia-settings -q GPU3DClockFreqs?

Code:

  Attribute 'GPU3DClockFreqs' (mescalito:1.0): 562,2800.
    The valid values for 'GPU3DClockFreqs' are in the ranges 562 - 1124, 700 - 3360 (inclusive).
    'GPU3DClockFreqs' can use the following target types: X Screen, GPU.
  Attribute 'GPU3DClockFreqs' (mescalito:1[gpu:0]): 562,2800.
    The valid values for 'GPU3DClockFreqs' are in the ranges 562 - 1124, 700 - 3360 (inclusive).
    'GPU3DClockFreqs' can use the following target types: X Screen, GPU.

mine is this, the same as before overclocking...
and if i set it directly from the cli:

Code:

$ nvidia-settings -a GPUOverclockingState=1 -a GPU3DClockFreqs=600,700



ERROR: Error assigning value 39322300 to attribute 'GPU3DClockFreqs' (mescalito:1.0) as specified in assignment 'GPU3DClockFreqs=600,700' (Unknown Error).


ERROR: Error assigning value 39322300 to attribute 'GPU3DClockFreqs' (mescalito:1[gpu:0]) as specified in assignment 'GPU3DClockFreqs=600,700' (Unknown Error).

and again, nothing changes
please, has somebody any clues on this?
thank you.

Can someone please link me to the miner? The one for the groestl.

I do not see it in the first post.

It wasnt ment as insult.
Just trying to get rid of this false understanding of mining, otherwise this will stick around forever :S

wrong thread.
your looking for this: https://bitcointalk.org/index.php?topic=475795.0;topicseen

Well it was read as an insult to me, the same way you read what i wrote the way you did

This thread is becoming worthless...more bickering and misunderstanding than actual useful info.

Christian, have you thought about just posting most of the pertinent info and comments on cudaminers forum where we can stick to the topic instead of this 600 page monstrosity?

Just pop in here and post when new versions come out...

[cbuchner1]

This thread is becoming worthless...more bickering and misunderstanding than actual useful info.

just my 2 cents... miners are indeed "making blocks", as the first transaction in that block is the one that grants the miner the block reward. And that transaction is sure made by the miner's wallet (for pool miners it's the pool's wallet). All the other transactions in the block are collected from the network, verified and stuffed into that block too. And the hash (the "proof of work") is the remaining ingredient that makes the rest of the network accept and forward that block

It is indeed the intention to replace this thread with the cudaminers.net forum. 600 pages make it too hard to find useful information.

Well let us know when your moving over there properly so we all know to move over aswell

for anyone interested i just posted a quick guide on compiling ccminer and cudaminer 32Bit over at cudaminers.net
http://www.cudaminers.net/forum/build-info-for-windows-thread.html?pid=270#pid270

i have made it as simple and easy to follow as i can

Thanks so much.

EDIT: Was out to dinner.

I am looking for this one from page 620 quote 11200

"okay, the faster version of cuda_groestlcoin.cu is in the repo.

You should see some notable speed-up on Compute 3.0 devices. Not sure about 2.0 and 3.5 - test yourselves.

My rig with 3 ASUS MARS (6 x GTX 760 cores) is doing 24.5 MHash/s Groestlcoin with this code.

In comparison the 3x 780Ti rig is doing 38 MHash/s with some yet unpublished code (this unpublished "killer groestl" code currently only benefits Compute 3.5 and 5.0 devices...).

Christian"

Lol you beat me to it. I was planning to do screen shot tutorial but apparently you were faster.

[bigjme]

Bored more then fast any recommendations for it i will do

[ManIkWeet]

Just noticed that perhaps the title of this topic should be changed, it isn't exactly just Litecoins anymore now is it?

I think it is complete, so i got nothing. Nice job!
