1  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN] profit switching auto-exchanging pool - middlecoin.com on: August 21, 2013, 06:33:25 PM
I'll ask again since nobody replied the last time...

If difficulty doesn't matter, why do pools even have a choice on what difficulty to go with? Why is there VarDiff? Since difficulty is meaningless, people who spent all the time developing those systems (as well as those who implemented them into their miners) wasted their time on something that supposedly means absolutely nothing.

Since difficulty has no real value, every pool/miner should be set at a hard-coded 1024 or 2048 or (insert difficulty here). We clearly have no need for more than one option.

the .15 payouts(would be making ~.24 JUST ltc'ing

This pool does not pay out everything you earned in a given 24 hour period. If you were to stop your miners cold, you're still going to get paid the next day, or even 2. As I understand it, there's a buffer that builds up due to the time it takes for blocks to mature, to transfer funds to exchanges, do the exchange itself, and transfer them back out.

In order to understand what you're making in a day, switch one of your rigs to a separate address, and run it for a specific amount of time (the longer the better), and then disable that address. That way, you have real numbers with a known amount of time, and you can calculate how much you're making per unit time.

h2odysee,

Exposing which coins you are going to sell next is likely to hurt the performance. It is too easy to manipulate the market in front of your dumping.

===

If your value proposition is to keep it simple (miners give you scrypt hash power and you simply give BTC back), then I do not see the point to get all the internal stats.

Someone who "need" all the internal stats is likely someone with the mindset to control all the steps. Good for them, but they will unlikely be satisfied with anyone else fully automated solution (which will sometimes do unprofitable moves) or the management fee. Why bother.

This is similar to choose to trust (or not) a Mutual or Hedge Fund. You give up control to the managers, and what really matter is how much money end up in my pocket.

Personally, I don't need the micro-management details to evaluate if your pool is good compare to my other approaches (and the time I have to spend on these). I just need to monitor the BTC/Hash rate at the user level. It is that simple.

===

Furthermore, public scrutiny into your automated strategies will slow you down from adapting your design. You will have to constantly explain your changes rather than being creative (and more profitable?).

===

Good idea. Keep up the good work.


Well stated. I agree.

Thanks for all the posts,I tried unhooking every piece of hardware I didn't need and apparently the one causing the restarts was the dvd drive.
Now that I disconnected it,it has been working fine for 6 hours+

Very interesting.

Just goes to show you, try EVERYTHING and try it one at a time.

I'm glad you seem to have found the solution!

GreatBug -

Are you able to provide any verification that you're the current owner of the shares that you're selling?

What OS are you using. If Windows, is it a BSOD?

I have a similar problem with one of my rigs. Although I didn't run memtest, I did run the built in Windows Memory Diagnostic tool (Control Panel -> Administrative Tool -> Memory Diagnostic). This test essentially froze. I swapped out the memory and now I'm hashing away. The BSOD would happen pretty quickly before.

In the past, I've also had random BSOD and crashes due to a bad HDD that even passed HDD checking tools like spinrite!

Best of luck!

9  Bitcoin / Mining software (miners) / TightVNC seems to crash display drivers on: May 26, 2013, 02:16:54 AM
Howdy ya'll

I'm having a problem. I have many rigs running stable without touching them. However, when I start playing around and remote desktop-ing into them, the display driver for the primary card (GPU 0 when I use --gpu-reorder in cgminer) crashes, and the card goes SICK.

It's not a 100% reliable correlation, but when I leave them alone, the drivers run stable.

I'm using Windows 7 32 bit, AMD 13.4 drivers, and TightVNC 2.7.

Anyone else experience this?

I'm happily running 4 rigs all with 4x 7970s (16x7970s total) without powered risers and they run for days on end. They only stop when i decide to "fettle". I keep them cool though - all temps under 65 except one that runs hot for some reason with a high of 75. Could it be a heat issue?

Also what PSU are you using as it may be that it's wobbling under the load?

I've tried a Seasonic 1250w and a Rosewill Lightning 1300w, with similar results.

I have cgminer set to auto-fan with a target temp of 75 degrees. They run at 72 an ~50% fan.

I haven't considered that it can be a temp issue. I ran a single card like this for an entire week without issue.

Just FYI:  I got my new risers in today and that fixed this problem.

Boozer do you use powered risers for all the cards? Just wondering if I would need to get powered risers for the 16x16 risers in a 4 x 7970 rig or just the 1 x 16

Also can not having enough power from running unpowered adapters cause the machine to crash after being able to run for 10+ hours?

thannks

I too am wondering this.

I cannot seem to be able to run 4 cards for more than ~6 hours at a time.

I am now running 2 cards for ~9 hours. I'm keeping my fingers crossed that they will go indefinitely.

The only thing I haven't tried is powered risers. I'm looking to create two of these today on my 1x risers where I'll add 1 card at a time with the new powered risers.
12  Alternate cryptocurrencies / Altcoin Discussion / Help with cgminer, 4x7950, Windows 7 on: April 24, 2013, 04:18:20 AM
Greetings Bitcointalk!

I'm having trouble getting cgminer running for more than 12 hours at a time.

My hardware setup is:
- GPU: 4 x Gigabyte 7950 GV-R795WF3-3GD
- Mobo: Gigabyte GA-H61MA-D3V
- PSU: Rosewill LIGHTNING-1300  / Seasonic SS-1250XM
- CPU: Cheap Celeron
- RAM: 4GB
- HDD: Whatever

I have run cgminer 2.11.4 for 12 hours straight on a few occassions with these settings at about 580kh/s each card (LTC mining):

Code:
cgminer --thread-concurrency 16158 -g 1 -I 18 

I was running 13.3 beta catalyst and corresponding APP SDK.

However, after about 12 hours, cgminer would simply freeze. To resolve the issue, I tried:
- replacing the GPUS
- replacing the mobo
- replacing the RAM
- replacing the PSU
- compiling cgminer myself

None of this worked. I finally decided that it might be a software/driver issue, so I reformatted and reinstalled Windows 7. I installed Catalyst 13.1 drivers, the latest APP SDK, the latest cgminer 3.0.0, and nothing else.

Now I cannot find any thread concurrency values that do not generate HW errors.

My questions:
- Is it normal to have completely different cgminer "tunes" for two identical hardware platforms? For the above, even the older cgminer 2.11.4 doesn't work with the settings that I was originally running 12 hours with.
- Is it possible to not be able to find a --thread-concurrency value that doesn't product HW errors?
- Is it normal to tune each card individually, or to have a single globale --thread-concurrency setting?

I've been struggling with this setup for weeks, and would truly appreciate any help the community can offer!

Although I use lastpass, I do not use it for any financial transactions.

Having a totally centralized password database doesn't sit right with me.

Very cool. I like a lot of the designs.

Have you considered accepting LTC in addition to BTC?

Site looks nice, only recommendation would be maybe to add some pictures of the systems. Pictures make everything better   Grin

Agreed. Some pics would be good. A nice open air design is certainly not ugly!
16  Other / Beginners & Help / Re: How long until I can post outside the newbie area? on: April 24, 2013, 03:53:28 AM
You have to browse for 4 hours and make a few posts.

If you make your post in this thread, I'll quote it on the other thread for you, if you like.

Hmm. I have over 6 hours and I still can't post anywhere else. '

:-(

Two factor authentication is inherently more secure, being less vulnerable to a brute force attack. If you could swing it, I would urge you to go for it!

I hadn't thought of this. That's an excellent idea, and would solidify bitcoins place in the world economy.

What's up bitcointalk!

Long time lurker. Starting up a litecoin mining operation, and am looking to get some help with cgminer.

Here I am trying to get my post count up so that I can post in other forums.
