Increasing gpu clock & memory clock increases hash rate, instead of just gpu clock

works fine on lc.ozco.in by ip but not url I have found

host 67.210.248.11
port 9332
user Graet.5
pass p

is all i changed in litecoin.conf Smiley

Does not work with pools for me
To solo on windows:

1. Download litecoin daemon from github: https://github.com/coblee/litecoin/downloads
2. Go to C:\Users\{yourcomputer}\AppData\Roaming\litecoin\ and create litecoin.conf.
3. Put this in it:
Code:
# Network-related settings:
# Run on the test network instead of the real bitcoin network.
#testnet=1
# Connect via a socks4 proxy
#proxy=127.0.0.1:9050
# Use as many addnode= settings as you like to connect to specific peers
#addnode=69.164.218.197
#addnode=10.0.0.2:8333
# … or use as many connect= settings as you like to connect ONLY
# to specific peers:
#connect=69.164.218.197
#connect=10.0.0.1:8333
# Do not use Internet Relay Chat (irc.lfnet.org #bitcoin channel) to
# find other peers.
#noirc=1
# Maximum number of inbound+outbound connections.
#maxconnections=
# JSON-RPC options (for controlling a running Bitcoin/bitcoind process)
# server=1 tells Bitcoin to accept JSON-RPC commands.
#server=1
# You must set rpcuser and rpcpassword to secure the JSON-RPC api
rpcuser=user
rpcpassword=password
# How many seconds bitcoin will wait for a complete RPC HTTP request.
# after the HTTP connection is established.
rpctimeout=30
# By default, only RPC connections from localhost are allowed. Specify
# as many rpcallowip= settings as you like to allow connections from
# other hosts (and you may use * as a wildcard character):
#rpcallowip=10.1.1.34
#rpcallowip=192.168.1.*
# Listen for RPC connections on this TCP port:
rpcport=9332
# You can use Bitcoin or bitcoind to send commands to Bitcoin/bitcoind
# running on another host using this option:
rpcconnect=127.0.0.1
# Use Secure Sockets Layer (also known as TLS or HTTPS) to communicate
# with Bitcoin -server or bitcoind
#rpcssl=1
# OpenSSL settings used when rpcssl=1
rpcsslciphers=TLSv1+HIGH:!SSLv2:!aNULL:!eNULL:!AH:!3DES:@STRENGTH
rpcsslcertificatechainfile=server.cert
rpcsslprivatekeyfile=server.pem
# Miscellaneous options
# Set gen=1 to attempt to generate bitcoins
gen=0
# Use SSE instructions to try to generate bitcoins faster. For muliple core processors.
#4way=1
# Pre-generate this many public/private key pairs, so wallet backups will be valid for
# both prior transactions and several dozen future transactions.
keypool=100
# Pay an optional transaction fee every time you send bitcoins. Transactions with fees
# are more likely than free transactions to be included in generated blocks, so may
# be validated sooner.
paytxfee=0.00
# Allow direct connections for the ‘pay via IP address’ feature.
#allowreceivebyip=1
# User interface options
# Start Bitcoin minimized
#min=1
# Minimize to the system tray
#minimizetotray=1
4. Make this your litecoin.conf in the reaper directory:
Code:
host localhost
port 9332
user user
pass password

protocol litecoin

worksize 256
aggression 18
threads_per_gpu 1
sharethreads 20
5. Run litecoind.exe and let it catch up with the network.
6. Run reaperDEMO.exe.  If it throws a kernel error, go into the directory.  There should be a litecoin-reaperv13.XXXXX.bin file where XXXXX is your architecture.  Rename litecoin-reaperv13.Cayman.bin to litecoin-reaperv13.XXXXX.bin.  Reaper should work fine now.

I had it running on a msi 6950 twin frozr at 310Khash,
it does work, but its a waste of time and power....

3phase if so not for long, checked the price of LTC in the last hour or so? lol

Its not useful though, i can mine enough btc to buy 3-10 times the amount of ltc this thing could mine

its just silly
Did you miss a decimal point somewhere?
At current prices and difficulties it's almost par.

anyone got any results from an nvidia card?
Nope, it's not source it's precompiled for 2 AMD chips, but theoreticaly if we get source it will perform ok on Nvidia.

Well yes, but cause this implementation depends most of GPU-memory speed i think this scrypt miner will run wit same/better results on Nvidia GPUs Smiley so it's not that worthless Smiley

now we can test the truth of the ltc-gpu-mining:

http://solidcoin.info/reaper.html

it works with my 5850 on http://www.litecoinpool.org

congrats!

LTC - 998kh/s // 920 watts: $4.354 (without energy-costs)
BTC - 1624mh/s // 950 watts: $4.874 (without energy-costs, but the more watt included, so: 1573 mh/s)

atm: btc-gpu-mining is 11.9 % more profitable then ltc-gpu-mining

I can't speak to LTC efficiency, but those BTC wattage figures are using a very inefficient Bitcoin GPU miner. A good GPU system can get about double that performance for the same wattage.

we can't compare apples and oranges, on the more efficient rig, you will do the btc- and ltc-mining with lower watt, because of the higher productivity of the rig...

now (all) can realize your noob-status...
very interesting for furthermore postings  Grin

I would take that personally, if you had actually understood what I said.  Let me know when you learn to code, and I'll try to act hurt over your opinion of me.

I have no favorite horse in this race.  You would do well not to mock me when I point out that yours has a broken leg.

yeah, now we are at a coder contest...

i think i'm in the wrong movie...

you can't see the wood for the trees...

thanks for this very interesting posting...

haven't you realized, that sc is just cpu AND gpu-minable?

Haven't you (all) realized that if you can do it for LTC, you can do it for SC?

I see. You don't care about Litecoin, you just want some free money from your old stuff, just like the botnets. If that's the only reason for Litecoin's existence then why would anybody buy litecoins? To feed you and the botnets?

Not quite true - I would sincerely love to see a modern decentralized cryptocurrency make old-school notions of fiat currency like the dollar and euro completely obsolete.  I didn't join this community back when BTC had a value of $0.04 each (nor do I mine LTC, currently worth less than a US penny each) hoping to strike it rich.   Roll Eyes

At worst, you could say that I believe in hedging my bets.  I won't buy $4000 in GPUs just to help seed a cyptocurrency, and if I make "some free money from your old stuff", hey, cool.

That said, we post in a community who already understands all of this (and still has legitimate disagreements - bordering on holy wars - on how it should all work).  But fiat currency or not, any "money" other than food, shelter, and sex, has no value except what a sufficiently large population agree it has.  We need to consider what the average Joe sees in this - And Joe has no reason to take an interest and play along if he can't join us without an unreasonable barrier to entry.

Bitcoin passed that barrier quite a few months ago, and today, "Joe" sees it as a subject of ridicule - "Oh, you mean that thing where the Russian mafia buys up all the ATI cards so they can launder their money?" (and don't even get me started on how many idiots haven't the faintest clue about the real meaning of a Ponzi scheme).  A CPU-only (or at least, GPU/ASIC unfriendly) BTC variant, I believe, has a lot of potential to let all the latecomer Joes try to get into the game again.


haven't you realized, that sc is just cpu AND gpu-minable?

Haven't you (all) realized that if you can do it for LTC, you can do it for SC?  Though different core algorithms, they use the same underlying assumptions about the cost of memory accesses to limit GPU performance - Which mtrlt may have proven false (we still have no proof of that).  I mentioned both LTC and SC in my post because I mean to refer to both.  Nothing short of a "hard" serial algorithm will prevent GPUs from doing it better than CPUs; that, however, would tend to break the whole idea of a distributed currency (if 200 people can mine independently more efficiently than one person with a bigger rig, then most likely so can 200 ALUs vs one full CPU).

I don't really have an answer to this, but I think we need to discuss it without disintegrating into "my chosen BTC variant works better than yours".
