Yup...  Got a 6870 undervolted to 1000mV @ 850MHz and it's doing 280 kh/s and stays in the 60C's at only 50% fan speed.

Yep, looks like I'll have to wait until somebody fixes this.


v13 beta 3:

Fixed compiling for Tahiti (79xx), and probably many other cards too
Using Catalyst 12.2 or newer is now recommended

The CL code is specific to the hardware in the 5xxx and 6xxx series...  it doesn't compile at all for nVidia cards and it's not surprising that it doesn't compile for the 7xxx series too.

BCX: You'd be better off hiring a team of security professionals to find out all the security holes in SC2 with that kind of money...
2905  Alternate cryptocurrencies / Altcoin Discussion / Re: LTC GPU Miner Source Code Reward Thread on: March 13, 2012, 12:32:35 AM
Wait are the speeds being listed as actual speeds of running litecoin and its scrypt algorithm?

If so then the network hashrate should be jumpin sky high right now.

Please clarify...

thanks Grin

The price of LTC is comparable to the price of BTC based on per watt averages.  Mining LTC is slightly more profitable based on the average price of LTC right now, however most people would rather mine BTC as there is much greater liquidity and lower volatility (LTC price has been fluctuating on an order of magnitude for the past few months).

Still can't get the kernel to compile for nVidia... it just hangs at clBuildProgram program.  Sigh.

Anybody can upload Reaper 13 to other sites please? Cannot access zerosignalgame.com   Sad

I get 315 kh/s on a 6870, which is impressive.  This is with the windows binary.
2911  Alternate cryptocurrencies / Altcoin Discussion / Re: LTC GPU Miner Source Code Reward Thread on: March 11, 2012, 10:47:10 PM
Compiled it on linux, it just hangs for me

How did you get it to compile?

-MarkM-

What I did:

In the cmake list (CMakeLists.txt) remove everything reference cl libraries and place the cl.h/cl.hpp/other files wanted in the directory
Change import <CL/cl.h> to "cl.h" in the AppOpenCL.h
Tweak any other weird errors you get, I think one of the files is missing "include <math.h>"
Compile with the cmake script included
Then try to make the cl kernel compilable, that's where I'm at.  Can not get it to compile on nVidia at all though.
2912  Alternate cryptocurrencies / Altcoin Discussion / Re: LTC GPU Miner Source Code Reward Thread on: March 11, 2012, 10:34:21 PM
works fine windows 7 X64

Nope, it crashes with nVidia for me on either OS

edit:
also, these curious functions

Mtrlt just released his in IRC. windows x64 and x32 and linux source.


We have to download it using our IRC clients?Huh

Sent 500LTC from one of my wallets...  That's about 1600LTC there now and 10BTC.
2916  Alternate cryptocurrencies / Altcoin Discussion / Re: LTC GPU Miner Source Code Reward Thread on: March 11, 2012, 06:57:30 AM
I'm very much wondering if the Reaper miner for LTC is just a simple permutation of the regular Reaper miner... It doesn't look like it'd be very hard to port to LTC if someone had a day or two on their hands to dedicate to this, but I don't have time to play around with it.

http://solidcointalk.org/topic/425-reaper-v12-a-standalone-cpu-gpu-miner/

AppOpenCL.cpp/.h : Port the memory mappings to those required for LTC.
reaper_????.cl : Port the scrypt.c hash code to CL ( https://github.com/pooler/cpuminer )
RSHash.cpp/.h : Port this from scrypt.c as well, for checking the block hash on work done by GPU.  Reaper includes the genesis hash and related functions, but I'm not sure the miner uses it.

2918  Economy / Speculation / Re: bitscalper anyone use this ? [PASSWORDS LEAKED] on: March 10, 2012, 05:55:37 AM
I think I had 3 BTC in there or something..  E-mailed him, never heard back.  It was obviously a ponzi scheme, but I didn't want to bail out after only making $0.50 which was how much I'd accrued before the whole thing shut down.
2919  Alternate cryptocurrencies / Altcoin Discussion / LTC GPU Miner Source Code Reward Thread on: March 09, 2012, 02:37:10 AM
Hey,

I want to offer 500LTC to the first person to give the source code for an LTC GPU miner.  The code must be compilable on nVidia and AMD GPUs.

I wanted to start this thread to get other people involved too.  I think it may motivate ssvb to finish his miner quicker and release to the public if everyone is willing to pitch in some.  So, if you want to pitch some money into this too, let the people out there who are working on LTC miners know with some offers.

When the GPU miner is released I'll put the authors LTC address on here so you can offer your coin up to them.

2nd edit:

Coblee has set up a reward address.  Please forward all donations to this LTC address:
Code:
LgpuY1d6ncPkN9XYVGWraiohJXTqSKdqtL
Current reward: http://abe.liteco.in/address/LgpuY1d6ncPkN9XYVGWraiohJXTqSKdqtL

Or for BTC:
Code:
1gpuEVUaML1pXEUNVeREnQqitfv1DeUMD
Current reward: http://blockexplorer.com/address/1gpuEVUaML1pXEUNVeREnQqitfv1DeUMD

edit: I may as well keep track of people willing to donate here too.

List of People Giving BTC/LTC for a miner:
TacoTime - 500 LTC
tatsuchan - ? BTC/LTC
Bitinvestor - 10BTC

I think RS & friends aren't releasing the source code now because they're afraid it'll make LTC mining more popular by offering an nVidia GPU minable currency not SC2... sigh.

There's another GPU miner coming soon, though.
