Bitcoin Discussion Thread Part 2

Out of curiosity, why don't we have a [H]ard|Pool?

Not enough hashing power to make it worthwhile. And there's plenty of pools already established to join. There's really no need for another small fry.

The "how many Mhash/s" thread was up to 30-40 Ghash/s. What are the top pools producing. Maybe I just have a lot of pride in [H], but I think it would be cool if we created one of the bigger pools and made a name in BTC, much like we have in F@H.

NOTE: The above question is a honest one and not asked to start a flame war or anything.

Nowhere near enough people interested on this forum to be competitive with the larger pools who are producing well over a Terahash of hashing power. And it takes a lot of work to keep the servers up and running and continue to increase their load capacity as more people join.

Maybe a stupid question, but does anyone have a reference on what it takes setup wise to run a pool? I have a ton of server hardware sitting around just not familiar with how one would set it up, manage shares and etc.
 
Does anyone else have trouble connecting to Deepbit using Phoenix? For some reason I can only connect with Poclbm.

Evil Juggalo how do you setup flags on mtgox to auto sell and buy for you?

Also. I moved to ars bitcoin and I'm actually seeing a higher BTC average for a 24 HR period over btcguild.
Click to expand...

well, its automatic to a certain extent, but it helps e from losing out..

I setup 3 buy flags in increments, and setup 3 sell flags in increments.. But you have to have enough both coins and cash to cover all transactions when they are set..

I just always have something like this queued up since I cant figure out the automated API thing.

Buy - 5 Coins @ 13.75$
Buy - 5 Coins @ 13.50$
Buy - 5 Coins @ 13.00$
This way, as the price drops it keeps on buying instead of blowing it all ont eh first buy

Then setup selling the same way
Sell - 5 Coins @ 14.75
Sell - 5 Coins @ 15.00
Sell - 5 Coins @ 15.50

Anyone using the Asus 5770 CuCore?Someone told me that it is the worst card in 5770 line of every brand.Thoughts?
Click to expand...

Using one right now. Works fine. Not sure why it's the worst since it has a reference PCB so you can control the voltage through MSI Afterburner than than with Asus Smart Doctor.

I also had a MSI 5770 Hawk and that thing was a beast. Loved the cooler (fairly quiet) and it overclocked nicely. Too bad I sold it because I needed the money. :(

How does that work for you? I've been watching and it doesn't seem that it goes bellow $13.90 and it hasn't hit $15 in several days.

Click to expand...

1) Start GUIMiner.

2) Set the Bitcoin client path: (Solo Utilites --- Set Bitcoin client path)
Now GUIMiner is aware of bitcoin client location.

3) If you've never opened your bitcoin.conf file and did not create a user/password in it:
- Set Bitcoin username/password: (Solo Utilites --- Create solo password)
- Enter any username and password of your choosing, GUIMiner will add them in the bitcoin.conf file.

4) Launch Bitcoin with server options. (Solo Utilites --- Launch Bitcoin client as server)
Note: You won't be able to launch it if the client is already running. (If your client is already running with the -server flag, you can skip this step).

5) Create a new miner (File --- New Opencl miner or New Phoenix miner or New Other miner your choice)

6) Server - Chose Solo from dropbox.

7) Enter your username and pass, created in step 3 (or if you already have user\password in bitcoin.conf - use those)

8) Choose device and fill Extra flags field with options if needed.

9) Click Start.

10) Profit

In the left lower corner you will see the following:
Difficulty 1 hashes: 0 (number will increase - it replaces the "shares" counter that is seen when pool mining and works as an indicator that all is normal). In the right lower corner you will see hashrate.

Thank you, I think I did all that...I found a reference to newer bitcoins not working in solo mode so uninstalled and regressed to 0.3.21

Reading further I learned about initializing bitcoin (downloading existing blocks?) got 136170 of those onboard now...slower than molasses.

Also seeing references to usernames having to be in the format <username.somethingorother> and I saw an error like that flash by but too quickly to really read.

Right now my error is "problems communicating with bitcoin RPC 0 2"
 
What miner are you using? Poclbm, Phoenix, etc? Also, the name formatting is really not required. I have guiminer with a backup solo miner that works just fine with a simple username.
You might also want to make sure to edit the bitcoin.conf file and add the following:

rpcallowip= You can use wildcards like 192.168.0.* or you can use all
rpcport=8332, this is the default port.

Newer versions of Phoenix and Poclbm have issues with solo mining if those are not specified.

Guys, if you're using a dummy plug, exactly what do you do in Windows to get the second GPU enabled? I have two GPUs, but there are four displays that I can choose total. One is my primary and the other three are disabled by default. When I check 'extend desktop' and hit apply, the checkbox automatically becomes unchecked on all three of the disabled monitors.

Does this mean there is an issue with my dummy plug's design?

Install the Catalyst 11.7 dev preview drivers and you won't have to use dummy plugs any more for Windows.
 
^^ Catalyst 11.6b also remove the dummy plug requirement. :cool:
 
Guiminer is not listing the extra cards in the device drop down box?

I had to restart twice for it to work, and now both GPUs work, but I can't apply any overclocks to the second GPU which is connected via ribbon, and have the overclock stick. The sliders for core and memory in Afterburner automatically go to 0, and the clocks stay the same for the second card. The voltage does get applied though, and it even screws up my presets.

This really defines "terra incognita".

P.S. you all have been an amazing help, thanks so much. There's a reason why I use this place exclusively for information and Q&A, it kicks ass. :)

Just got my power bill from last month, 2330 kWh and $315. :(

13¢/kWh sucks hard.

EDIT: I looked at my statement, last year in June I only used ~1550 kWh, but in October, I used ~2200 kWh. If I keep mining, I see October breaking $400!

My bill went up $70 last month, which is not bad considering it was 90F+ for a few weeks and I was mining between 2 and 6 GPUs. $.08kWh here.

It's 90°F+ every day here (unless it rains, which it's done at least once a week here), and my A/C is literally running on fumes, to make it worse.

The computer uses ~$1.75 per day that it mines with two 6970s at 1GHz/340MHz (pulls 565w from the wall), and I bought a small window unit to help cool down that room (and consequently cools down my entire house) uses ~$1 per day, it's really efficient.

I'm currently pulling in around .55BTC per day, so ~$231 per month with no difficulty changes (yeah, like that would happen :p). Minus the ~$100 per month for power and cooling

I was hoping to have at least paid off my second 6970 before I stopped mining, but I don't think that it will happen. That 50% difficulty increase last month really screwed me. :(

I think this weekend I will quit mining. It was fun, and I made ~$245 with it so far, but I don't like the heatdump and not being able to use my main rig for anything. :(

Well, using the latest GUIminer (with all the listed tweaks) and the latest AMD Catalyst 11.7 preview with APP 2.5, I'm now getting 890Mhash/s out of my 6970s at 1GHz.

Could you share the tweaks? also what miner are you using in guiminer? Like phoenix or what?

Just the default poclbm (the OpenCL miner).

Flags:
-v -w128 -f0 BFI_INT AGGRESSION=6

EDIT: Oh, the kernal tweaks. They are all present in the current GUIminer. Just download it and you're golden (along with downloading the Catalyst 11.7 driver pack).

Thanks for the reply, I had the latest guiminer going on both rigs, installed 11.7 and no longer have to run the cards in CF or run dummy plugs so that's nice. It also have me the ability to oc the way I want, I set 3 6970's and one flashed 6950 at 950/650 and one 6950 to 840/650 since it doesn't oc too well.

One rig has a 6970 and is going at over 400 mhash, beside it is the lower clocked 6950 going at 325 or so. The other rig has 3 of the 6970/6950's all going at 950/650 except the first card is going at over 400 mhash and the rest are going at a pathetic 300 mhash or so...The clocks seem to be stable, does 16x versus 8x really make that much of a difference? looks like when my 1x to 16x extenders come in i'm gonna be dealing with lots of mhash loss.


edit: also what's your cpu affinity set up like?
 
running -f 0 -w 128 -v flags on unlocked 6950s...getting about 350M per card

Actually that's not entirely true. The only tweak included in the latest release of guiminer is the initial 3% tweak I posted a long while ago. Since then there have been further improvements of the phatk kernel posted by a few OpenCL/Python/ASM coders in the official forums.

http://forum.bitcoin.org/index.php?topic=25135.0;all

You're welcome :p

You should be getting more than that. Are you not overclocked? With Phoenix/Poclbm and similar flags, my unlocked shaders 6950s both do 357mhash at core 900/mem 500
 
Yeah, don't use the plain OpenCL python miner, it's slow.
Use phoenix with phatk and the kernel tweaks I linked.
 
I just broke 400 mhash/s with my 5850 at 925/300.... =D

Phoenix miner with the tweaks. aggression at 7 with worksize at 256. Exit msi afterburner and mhash jumped an extra 23 for me. Pulling about 535 watt at the wall for 1 ghash/s. Not bad. I managed to shove 3 cards into my dfi ut p45 board.

How does exiting Afterburner cause you to jump 23 Mh/s??
 
Just got the HD5770 Hawk for $150.

Currently i'm running @975/600,giving me ~200Mh/s.The problem is it stays at nearly 80 degrees Celsius with fanspeed @95% (on Auto).Am i missing something?Is it really that hot?My old HD4870 Cyclone peaked @76c with fanspeed @85% on much hotter days.

Edit:I got it from another guy,he used it for 3 months and i noticed that one fan is not easily to spin as the other,is that the sign of a defective fan?

I experienced the same performance drop by having a hardware monitoring app open while mining. In my case it was RealTemp. I also got the same drop if I open any website that contains flash (newegg front page, youtube, even the [H] front page and many others).

I investigated all of that more than 2 weeks ago and discovered the FASTLOOP=false and AGGRESSION=7 trick when using the then recently released guiminer 20110701

http://hardforum.com/showpost.php?p=1037458006&postcount=291
Lorien said:
If anyone has time please try different AGGRESSION levels and set FASTLOOP to false.
I want to confirm these crazy increases I'm seeing. In previous versions neither of those settings made much of a difference so I pegged AGGRESSION to the max before it made the system too laggy (11 in my case).

Now I started a new set of tests with various levels of aggression. Levels 1-6 did nothing, and in fact decreased hash rate. When I got to 7 I saw this with nothing running but the miner:
The readout was erratic, it jumped from 460 min to 535 but stays around ~487. I have repeated this now several times across several reboots. I also tested different levels of Powertune, and 8% seems to be the most effective (for this card at least).

If I opened a browser window with about a dozen tabs I got this:

This is with a browser open with just one tab, taken just now:

After that I investigated further and narrowed it down to flash/java

Lorien said:

- Close all open programs.
- Start mining with whatever regular flags you have but use AGGRESSION=7, note the hash rate.
- Open firefox or any other browser you use and log into your g-mail or hotmail account, or go to the main newegg.com page or open youtube and play any video. Note the hash rate.

Did it decrease? If so by how much?

If it decreased, close the browser and note the hashrate again. Did it go back up?
I'm trying to confirm flash is the culprit here.
Thanks
Click to expand...

If I opened a page with java or flash in it, my hash rate plummeted down to ~414-417Mhash/s and it stayed there flat without moving and yes hardware acceleration for flash was disabled all along. Because of this I've simply resorted to block everything flash related with Noscript/AdBlockPlus and that fixed the problem.

Re-post and another issue:
I ran Guiminer for a few minutes and the PC locked up,after a few seconds it recovered and gave me the warning of "driver not responded and has recovered" and "polblm has crashed".What should i do?Happened since 2 days ago with my old 4870 and happens more with my 5770.
 
The card is overheating and is obviously not stable at full load. You could try switching fan control to manual and cranking it up to at least 70% but you mentioned that one of the fans is not spinning properly. Just becaause of that I'd demand a refund and return the card.
