GUIMiner-scrypt: A GUIMiner fork for mining scrypt chains

[anonadeus]

Got a Sapphire HD 7970 3GB OC w/ Boost that gets ~500-600khs with CGMiner in GUIMiner-scrypt.
I can't seem to get Repaer to work though, I get

 "Error 52 getting work. See http://curl.haxx.se/libcurl/c/libcurl-errors.html for error code explanations."

Any suggestions?

I was able to open guiminer , but now it doesn't open and just stays on the taskbar , tried reinstalling it same error , any Ideas Taco ?


running windows 7 64bit

You need to install CUDA toolkit for it to compile kernel

hi tacotime

can you describe the steps we should process for win+nvidia because i ve tried many things but no success

I second this

Delete C:\Users\You\Appdata\Roaming\poclbm\poclbm-scrypt.ini

It's a bug with wx where for some reason it puts the program 5 monitors away

Thank you so much for writing this, TacoTime. I built my first rig after your Noob instructions thread, named it TacoMiner.

Well, TacoMiner is running now at 561 K/hs, which is nice but it seems like only one of the 3 7950's is working.

How do I turn the other 2 on ?

The first LTC I mine will go to you

Hi, make 1 cgminer or 1 reaper for each card, then change the card number in the drop down menu for device to use a different card

im trying to connect miners to my main that is mining on p2pool. and it keeps saying connecting, but fails i tried my IP and my local IP. and no dice any suggestions?

I will have to try later when I get my nvidia rig set up, I've used reaper + linux but not reaper and windows for LTC mining

My 7970 is running fine in GUIMiner-scrypt (CGMiner), but I can't seem to get the 5850 to connect to a pool. I've created another worker and put in the correct server/port info, any ideas? Does the card need to be plugged into another monitor or should I get a dummy plug?

[tacotime]

You should just be able to select it from devices ("Cypress PRO")

[anonadeus]

Doh, computer just needed a good old restart. 7970 on low intensity is doing 510khs, 5850 is doing 260khs. Time to get tweaking I guess. Thanks for your help Taco.

I have no idea how to do that. Can you throw me a link ?


EDIT : ah, it's in GUIminer-script itself.  After adding more miners, I still can only see ONE 7950 ( tahiti ) GPU. While PCI-E slot 2 and 4 are both connected to one. I feel like i'm missing something more basic. Like the board isn't detecting the cards. I have the board from your noob thread, the z77

I'm starting litecoin fresh.  I downloaded and updated the wallet.
Installed your awesome gui miner and started a 5870. Also using the stratum proxy.
I used the default settings for the 5870 and pointed it to coinotron and it worked.  So I created a new miner tab to put my 5770 on and used the default settings but it made my screen unstable and got 67 stales and no good shares before I quit it.  So I tried it again with intensity of 10, the screen was better, but still only stales and no good shares.
So I put the 5770 back on bitcoin for the moment and it works fine.

The 5870 continues to run fine at default settings 312 khash/s for all of those who want to know.

Hey taco, can you tell us anything about the discrepancy between the GUIMiner kHash and the pool displayed kHash? I tried this on different pools and it's always lower. And yes, also with reaper. Any explanation?

I would say it's variance, I'm using guiminer on 4 rigs and the pools are reporting the same thing as the rigs.

I'm getting an alert "errors occured" and the program crashes right after starting.

Code:

On Win Xp x64

Any ideas why?

Got the same error on a Win7 32 machine.  Won't run.

I did another install on a Win8 machine and it works fine there.  Nice work, Tacotime.

Now, how to get around that error on the Win7 machine?

Install 64-bit OS.  I don't know why that error comes up on Win7 64-bit, though.

Eventually I will build a 32-bit version on XP for more compatibility, I just haven't gotten around to it yet.  On my fresh 64-bit installs of Win7 64-bit it works fine, though.

For me as well, guiminer consistently under reports khash. This is true of 4 different rigs with 7xxx cards. Not a big deal, b/c I can always just check long term hashing with the pool which is the most reliable measure, but it makes hardware tweaking a little more difficult if I can't accurately judge the changes at the machine level.

This is strange.  I tested it today with a 7970 and I got the same results in cgminer from the console as with the guiminer.  The program just pulls the rates in KH/s from stdout, so they should be the same.  I noticed that for some reason after a while rates can decrease, though.  I will have to look into it and figure out what's going on.

I'm getting what I believe to be is very poor performance from GUIminer-scrypt with my Radeon 7950. I see people talking about 500-600 Khash, but I'm lucky to get above 350! I'm not sure what would be causing the problem, so let me toss out some thoughts:

1) Mining on ozcoin.net (newlc.ozco.in:9332) -- they seem to be having DDOS issues at times, or at least sluggish response times. Could that be the problem?

2) CGminer vs. Reaper -- Reaper keeps crashing and I haven't gotten it to work right yet, so I'm on CGminer.

3) Settings might be bad. Currently, I'm getting best results using Thread concurrency 8192, worksize 256, vectors 1, intensity 13, GPU threads 2. (Without the GPU threads 2, it's more like 220 Khash!)

4) Maybe a poor driver choice? I'm currently on the Catalyst 13.2 beta I think, but I was going to upgrade to 13.3. Thoughts?

Okay, that's all for now. For what it's worth, hardware is Bloomfield i7-965X at 3.6 GHz, 12GB RAM, SSD for storage. I get around 450Mhash on Bitcoin with stability using same GPU. Current GPU clocks are 965/1250. HELP!?
