1  Bitcoin / Pools / Re: [8500 GH/s] Slush's Pool (mining.bitcoin.cz); TX FEES + UserDiff; ASIC tested on: April 20, 2013, 12:18:18 AM
Alright, great you've got it back up! Good work slush!
Question though...

Is it alright to use any three of these still?

stratum.bitcoin.cz
stratum2.bitcoin.cz
stratum3.bitcoin.cz

I'm still on 3 since that's what worked yesterday when the others didn't. Just need to make sure. Thanks in advance.

I just migrated pool to another datacentre (longer story later...). There are three loadbalancers behind every of following DNS:

stratum.bitcoin.cz
stratum2.bitcoin.cz
stratum3.bitcoin.cz

So nine machines filtering the traffic right now. Balancers behind stratum.bitcoin.cz seems to be dead from the attack, but time to time I see some accepted connection. Once the connection is established, it will be kept by the balancer (that's nice advantage of Stratum protocol).

Please try these URLs in your miners, some of them will, at least after few tries, work for you.

Not working. The only one which gave any signs of life was stratum3.bitcoin.cz:3333 and it soon after crashed cgminer.

And the moral of the thread is use p2pool? What about slush's?

bah, second day I can't connect. Is he really getting DDoS'd this bad? Someone mentioning he's switching servers? Hope that goes smoothly and hastily. My dedicated miner is sitting crying for shares.  Cry

6  Bitcoin / Mining software (miners) / Re: CGMINER GPU FPGA overc monit fanspd RPC stratum linux/windws/osx/mip/r-pi 2.11.4 on: April 07, 2013, 11:46:24 PM
A couple thoughts:

- lower the GPU memory to 900.  I don't think you'll be able to do this with cgminer, you'll need to use MSI afterburner.  It'll make it run cooler and use less electricity.
- no need to specify vector or work size.  cgminer is smart enough to know what's best for your 7970s

M

I believe cgminer will default to -w 64 which is best for 7970's.

Thank you very much for your help and input.

I've just edited the settings as follows:

cgminer -o stratum.bitcoin.cz:3333 -u username -p password -I 9 --gpu-engine 1100 --gpu-memclock 900

I set the Memory Clock to 900MHz in Afterburner before running cgminer with the above settings. Does everything look good now?

edit: getting 650 - 670 Mh/s on each card.
7  Bitcoin / Mining software (miners) / Settings for two 7970's in Windows on: April 07, 2013, 10:28:44 PM
I have two "Sapphire Radeon HD 7970 OC with Boost 3GB" cards and I'm running cgminer currently. Bitcoin is a complicated and in-depth topic that I'm not too familiar with. And neither am I well versed in mining. So I would like some input on the settings I'm using for two cards. I disconnected the CrossFire ribbon cable, and I disabled CrossFire in the Catalyst Control Center. With an OC from 950MHz core to 1100MHz, I'm using the following:

cgminer -o stratum.bitcoin.cz:3333 -u worker -p pass -I 9 --gpu-engine 1100 --gpu-memclock 1425 -v 1 -w 256

I have MSI Afterburner installed to manage the fan speeds relative to the temperatures.

Does what I have look fine? The machine is a dedicated miner.
8  Bitcoin / Hardware / Sketchy BFL Phone Number on: February 11, 2013, 10:50:47 PM
When I call the number on the BFL website, it takes me to a voicemail for Dave McClane, I believe his name is. I guess I don't know enough about the BFL business yet, but it strikes me as odd especially when they talk about "our team" on the jobs page, that their line of contact is a personal voicemail. Why doesn't that "team" have a customer support phone number? If they are so backlogged with e-mails about shipment dates and a misplaced account login URL, are they going to get around to cancellation e-mails before those orders ship?

Given the demand and likely large quantities of orders queued up, I don't see why such a business would operate without a customer service phone number. And some dude named Dave who doesn't answer the phone during business hours -- what's the point?

I can't even get this working on Windows.

  • Installed Python 2.7 (x64)
  • Installed Twisted
  • Installed Zope.Interface
  • Unzipped the files into C:\Python27\Lib\site-packages
  • Created bitcoin.conf in: C:\Users\Me\AppData\Roaming\Bitcoin
  • Typed:
rpcuser=<username>
rpcpassword=<password>
server=1
NOTE: I used a real u/n and p/w.
  • Made a "run_p2pool.exe" shortcut adding the following in the Target line: C:\Users\Me\Downloads\p2pool_win32_11.2\run_p2pool.exe <username> <password>
NOTE: <username> and <password> are the ones I used in the bitcoin.conf file.
  • Extracted cgminer to the Downloads folder as well.
  • Created a shortcut of cgminer.exe and edited the Target line as such:
C:\Users\Me\Downloads\cgminer-2.10.5-win32\cgminer.exe -o http://127.0.0.1:9332 -u <username> -p <password>
NOTE: I used the the u/n and p/w from the bitcoin.conf file.[/list]

I run run_p2pool.exe shortcut, then I run cgminer.exe shortcut, NO DICE!

What I see:
run_p2pool


cgminer:


Just wanted to make a d'oh note. I rebooted my computer and it works now.
I suppose it's because Twisted makes a registry edit and you need a reboot for that to take effect.

In other news, the above instructions will get you mining on P2Pool on Windows. (I'm using Win 8 x64)

Alright, so a "best" alternative to Deepbit would be Slush's pool?
11  Other / Beginners & Help / Re: Which mining pool and why? on: February 09, 2013, 10:31:13 PM
No one advocating Deepbit? I admit I haven't done much research for choosing pool, but why not Deepbit?

What would be the wait time before a BFL Jalapeno ships? Anyone know?

Those look great! How heavy are they, and how do they feel compared to other coins? I might be interested in a couple...
