1  Other / Beginners & Help / Re: How to get 2 x 7950 HDs working with cgminer?? Works fine with 1 card only. on: April 28, 2013, 03:12:58 PM
Although I am using GUIminer on Windows, I am using 2 7950's so i can give some insight here. I have tried mining with both crossfire on and crossfire off (just a flip of a switch with the control center). I have noticed MAYBE a 5Mh/s difference between the two, which i consider irrelevant. I also use this computer for gaming, so Xfire on is really the better option for me anyway. The cards are both HIS 7950 IceQ2's OC'd to 1150Mhz. I get just under 600Mh/s on each when i'm not running anything else. Your GPU1 will always run hotter, just because of the thermal dynamics of having 2 cards stacked so closely to each other. If you are using MSI afterburner (which I highly recommend), set the user fan progression so that you can keep temps of GPU1 sub 80c -my made up heat threshold. My curve is set so that if card is 70c, fan is 75%- 80c, 85% etc etc. Remember, through Afterburner I've Oc'd both cards from 950 to 1150Mhz so your results could vary noticeably if you opt not to go that route.

It's currently retracing. Broke 140, so we should see 160 next. If it pierces that, then 180. Trend is definitely bullish, but also lots of scared folks out there....MtGox is not well capitalized in my opinion, and will have challenges.
Bitfloor is gone, who's next?

Support and resistance and indicators like Fibonnaci rely on a certain amount of volume and walls of institutional and retail bid and ask entry orders and stops to really work. It is difficult to draw any sort of solid technical analysis conclusions off a trend less than 2 months old and at it's peak volume in USD, was only 35,790 coins.

I think that since it has and can go higher than 266 you are getting in at a good price under that amount. obviouly the sooner the better, as we can see today that it is rising quite a bit. say you had just ten coins, for every dollar it goes up you make ten, so if you bout at 100 you have made 435.10. we will continues to see the price go up as we start to go main stream.

for those of you who are just learning about bit coin I would say get in soon. yes there will be ups and downs but hold to at least the last ATH and thenif you sell you will be sitting pretty, but be prepared to kick yourself when the price goes to 500 and then to 1,000. just saying.  Grin Grin Grin Grin Grin Grin
It's greedy, dollar-minded thinking like this that messes up Bitcoin Sad

I hope all hedge funds, dollar investors, daytraders, stock brokers, and other scum from the old monetary system lose a SHITLOAD of money. So the only people remaining in Bitcoin are there because they understand and appreciate the ideology behind Bitcoin.

Here's the thing: you shouldn't see Bitcoin as a way to make dollars. You should see Bitcoin as a way to DESTROY the dollar.

If you fail to get larger investors into BTC, the volume and liquidity will remain anemic and the project won't go anywhere. Eventually, if big money enters the market, you will probably see leveraged trading accounts, hedges balancing between precious metals and btc, ETF's, small banks accepting conversions/issuing btc atms etc. Right now, if you look at the volume of any currency base besides BTC/USD, its pretty sad and that won't improve with a bunch of people buying and holding or purchasing little (in the grand scope of things) stuff online. If you get some VC's with some cash to burn in a new concept like bitcoin -watch it explode (it will probably make all home miners a thing of the past, but like gold, i don't see a whole lot of pan-sifters in the local river these days). When a market goes up and down $50 a day, you're dreaming if you don't think people start to see dollar signs. Even the most independent thinking, anti-establishment, anti-centralization thinking person has to eat and probably dislikes his or her day job. Not to mention, by the laws of supply and demand, if the market dynamics stay exactly the same as it is now, with little to no institutional investors, yet the monetary base continues to expand, where's all this price strength coming from? I can't buy gas or a sandwich with it yet so you're going to need some heavy hands to inject this thing with the juice needed for the next leg up in the absence of broad consumer acceptance on such a short timeframe.

Ok yea i understand. I started thinking about this because in the Eligius dash it gives you "Approximately xxxx BTC remaining to enter payout queue. Maintaining your 3 hour hashrate average, this will take at least another x days, y hours and z minutes at current network difficulty of 8974296.01." This time changes with fluctuations in the 3hr rate, so it makes me think there is actually pretty much what I'm talking about already out there, just working in the background. With time left and a decreasing total to get into the pool, given the difficulty, they're basically calculating a btc/min rate in the background to provide a rough estimate.

Oh well, something for grander minds than mine to consider.

BFL is real. I live about 20 mins away fromm their lab. Ive been there and saw all the different systems they are selling. Yes they did have a few of each up and hashing, not at full power because owner said the were still working on heat issues and software stabilizing. but all in all I believe them because I saw them with my own eyes, they gave me and my buddy a tour of the entire place. Its legit, slow, but legit.

You wouldn't be the one on reddit who just walked in and got an impromptu tour would you?
6  Other / Beginners & Help / BTC/sec rather than Hash/sec? on: April 24, 2013, 01:19:13 AM
So i'm sitting here looking at the hash rate i'm running right now and thinking to myself, "Man I'd like to know how fast i'm actually earning bitcoins at this rate, at this difficulty". Sure, one can go through a pre-made site or do the math them self and find a static number, but I'd like to see a constantly changing rate of BTC/sec. I feels like reading just the RPMs on your car's dashboard, factoring in what gear you're in, and determining your mph from there. Do any services include/have considered this? I'm picturing just a toggle more or less for eye candy's sake.

Pulling advertising can be an incredibly powerful tool to get things in motion. This is the largest BTC forum from what i understand and clearly to this point the admins have seen no reason to stop advertising BFL on the site. However, if this site did not allow BFL to advertise, their exposure would decline fairly dramatically, especially to newbs (who come to forums first to learn as much as possible about a new venture and can be especially vulnerable to too-good-to-be-true offers). So, if you want a company to respond and get the gears turning, you remove their public exposure until they can absolutely assure they're not a scam. I realize forums usually solely survive off of ad dollars so the likelihood of this happening is little to none but nevertheless its a thought.

I have this feeling that all the idiots who scream that BFL is a scam will just disappear and make new accounts later this year. And there will be a few nuts that believe that hundreds of forum users are being paid by BFL to act like they got working ASIC's.
who knows ))

He forgot the third group.

The people that bitch about their ASIC not going break even in 6 months. You know, an investment that makes over 10% a year is usualyl scammy... here in Bitcoin, people go nuts if something does not make 100% in 4 months Cheesy

Reminiscent of my days roaming the yahoo finance penny stock forums.
9  Other / Beginners & Help / GUIMiner connection problems & Phoenix 2 question on: April 21, 2013, 04:03:06 PM
Newbie, so please excuse the placement here.

When i first started mining, i was using Phoenix 1.7 with little issue (also only had a single 6950 at the time). Since i bought 2 7950's, i decided to go to guiminer for better organization and management of the two cards. However, recently i've been getting connection errors overnight which halt mining. GUIminer does not always restart the mining process so sometimes, whether i'm at work or asleep, no progress is made for hours. I'm considering going back to Phoenix (2 this time), but can't find any how-to's on the setup. 1.7 had vids and walkthroughs of what was necessary, but i haven't been able to find anything on how to get 2.0 up and running. Im just looking for a "create a file here, name it this, include this in the text, double click and wahla" kind of thing. I'm assuming i'll need 2 instances for the 2 cards. I'm utilizing Eligus' pool so i don't have a password or any of the credentials i've seen for other pooling methods. Even if its a redirect to a previous post i'd be grateful (although i've scoured the main phoenix post and haven't been able to put 2 and 2 together)

Thank you,
Rusty

Does anyone know if there was a limited release from BFL very recently? The Hashrate jumped to a new all-time high (could just be a consequence of mining popularity). Disclosure- I have not purchased anything from them, just a curious citizen.

Oh yea, and I have a Corsair AX1200 power supply, but also have my cpu oc'd and several drives (this comp is my daily driver). The HIS boards are surprisingly power efficient though so i still have significant headroom.

Although not an exact match (so you might just disregard this) i recently purchased 2x HIS 7950 3GB IceQ2's. The are both OC'd to 1150MHz Core. In crossfire, both cards average 570-595 MH/s. That's at stock voltage with a +20% power limit (MSI Afterburner). Could OC further as they haven't topped 78c at any point yet but i'm hesitant to run at 99% load fully OC'd for any long duration. (Just for reference, at 1200MHz both cards are over 600MH/s)

I've averaged 1.15-1.19GH/s total and enter eligus' payout pool (.16921943BTC) at current network difficulty every 3.5-4 days.

So for you, add a third card's stats, figure in that you may not be able to OC to this degree, and going with or without crossfire may result to different rates, and go from there.

Hello Everyone,

I just wanted to introduce myself to the forum. I'm new to mining, but have been lurking around news on Bitcoin for much longer (unavoidable if you read Zerohedge or watch Keiser). Anyway, i come from quite a bit of time in FX and the parallels and differences to BTC were too irresistible for me. The future in paper has me worried and it would appear that thought is shared here.

As for the meat and potatoes: I started mining not long ago with my OC'd Sapphire 1GB 6950, and was getting anywhere from 320-360Mh/s. This was decent for me and a good stable level to get acquainted with Phoenix, Eligius etc.  

Within the last week I decided to purchase 2 HIS 3GB 7950 IceQ2's (half for bitcoin, half for gaming i'll be honest). With crossfire, and both cards OC'd to 1100MHz Core, I get 550-570 on each card or  somewhere in the 1.1-1.2Gh/s range, which needless to say is a big improvement. Maintaining temps under 79c on the #1 card with both at 99% is also pretty acceptable to me.

Making money is probably most people's goals, mine too, but it's also pretty cool to think that if BTC is fully successful, i will have contributed toward unlocking an entirely revolutionary way of transaction. I can tell my kids oh yea Bitcoin? I helped create .00000000000000001% of those 21m coins. I mean, Bernanke can say he created $85b a month so why can't i have some fun too right?!

I assume that if and when these BFL contraptions get released, the gig will be up for anyone not willing to invest 15k in a rig. So until then I'll take advantage of the excitement right now, and once it's over for the small guy, back to games and my kickass new FPS.

Cheers,
Rusty
