i can mine with it, its just very slow and inefficient. anyways, something weird happened. i changed the flags and turned on the CPU affinity, and the speed shot up to 3GHash/s then slowed down to 996MHash/s... wtf? even still, i get nothing in the "accepted" and nothing shows up in the pool website. and after a while the mining speed just stays on one number and doesnt change
You cannot CPU mine, especially with a Sempron. CPU mining is worse than mining with nVidia, neither should be done by sane individuals.

Mike, Been a lurker on the thread, and now trying to setup Simplecoin. I have everything working, and in fact, my tests with one of my rigs appears to be working fine. However, I cannot load the Admin Panel. I have the link on my login, but when clicked it's a blank page and I get this error in the Apache error.log: [Thu Jul 07 02:36:39 2011] [error] PHP Parse error: syntax error, unexpected T_VARIABLE in /htdocs/adminPanel.php on line 43
Any thoughts, that line in my version of the code is: //Make sure an authPin is set and valid when $act is active^M if($_POST["act"] && $_$authPin == $inputAuthPin){
I'm thinking it doesn't think my account has a valid $authPin? But it does... Am I missing something?

1) You cannot destroy Bitcoins, you can only lose them (and they CAN be found, albeit with difficulty)
Uhh... Could you please give some info about finding lost bitcoins? Sure. Whenever your bitcoin client creates a new address, it randomly creates a public/private keypair of one of the 2^160 possible addresses. If (and it's a HUGE if, with a VERY low probability, but it's not ZERO) you create a public/private keypair that someone else has already created, you'll have access to the coins in that address in the block chain. Elsewhere in the forum someone was working on a program that would generate approximately 80,000 bitcoin addresses per second. At that rate you can create 80,000 * 31536000 (seconds/year) = 2,522,880,000,000 (2.5 Trillion) addresses a year. However, you'd have to run that for 5.7929891129617856×10^35 years, to exhaust all of the address space. And of course, you'd have to have a client that could handle that many addresses, which I doubt the default client can do. So, you'd have to come up with a way to check them all in the block chain to see if they are valid, which would slow down your rate. It's a big number. So, the odds of two people colliding with the same address are astronomically tiny. You'd be better off using vanity ID creation code to try to create a specific address, at least then if/when you found it, you'd know it.

I tried to resist feeding the Troll. I can't.
1) You cannot destroy Bitcoins, you can only lose them (and they CAN be found, albeit with difficulty) 2) With 700Mhash/sec, you're no where close to causing any real harm, you're losing what? 52 coins a year? Who cares, there are 21,000,000. 3) Every coin you lose, increases the value of the coins left in the network. I applaud your efforts. 4) You are INCREASING the liklihood that coins will be found by deleting your wallet.dat; because you're increasing the number of addresses that have lost coins on them. You'd be better off having all of your miners send them to a single address who's wallet.dat you've already erased, just saying.
Welcome to Bitcoin.

You're late to the party -- there's already a thread for this.
All the threads I found ended with: Sold Out Anyhow, just passing along the info, I see other people on these forums selling these same cards for $160 ea. Here they are for $130 ea. Ignore if you don't need them.

Economy / Speculation / Re: Why do people sell at 15 when the price could rebound to 30?
|

Because if you dont sell at 15 you will be sitting at 12 by the end of the day, sucks to take a loss, but the US dollars you got for those bitcoins, guess what, there still worth the same amount, today, tomorrow etc lol. I hope bitcoin picks back up, I love the concept and I am sitting on 50 more of them now.
Uh, yes, they're "worth" a dollar still. But a Bitcoin is still worth a Bitcoin too. The real question is, tomorrow, can you buy as much with that US Dollar as you could today? They just upped the price of Diet Pepsi in our vending machine today, so clearly, today I cannot buy as much Diet Pepsi as I could yesterday. But my dollar is still worth a dollar! So confusing....

Like I said... it's a content distribution network which helps you by distributing static content across multiple servers. Won't help with the getwork-queries which have to be real-time. Unfortunately.
Yep, that answers it and makes sense. Though I guess the operators could at least run their member website through CloudFlare to communicate to their end users. Since they tossed the botnet out of the system, a news page behind the login page, could allow for notifying miners of a new pool address/port.

CORSAIR 600T CASE, 3 FANS UBUNTU 11.04, AUTO LOGIN/AUTO REBOOT EVERY 6 HOURS 4 x 5830 SAPPHIRE / CLOCK 980, MEMORY 300 - 75 TO 85 DEGREES MSI 890FXA-GD70 MOTHERBOARD COOLER MASTER 850W SILENT PRO PS - 80Plus Bronze Certification CHEAP AMD SEPRON QUAD CORE 1TB WD SATA
Bit, did you need any extenders for that MoBo / Case combination? I'm currently running the exact same setup, but case-less. The wife is getting itchy about the motherboards just sitting on my desk and is insisting I close them up. How much space between the cards in that case? No extenders required, this MSI board can easily handle 4 cards. Not much space left between them maybe 5-8mm, but enough for ventilation. The case is very good space wise, it has 8 slots so plenty of room. I hear you about the wife, mine has been complaining since day one about the rig before and after I cased it up. I have the same board. Which slots are you using the cards in? Right now I have 3 cards with like 1" of space in between each, but am thinking of getting this case and that will require me to shuffle the cards. Looks like I'd have to put them in PCI-E 16x slots: 1, 2, 4, and 5, leaving 3 empty (going from the slot closest to CPU as 1). True? Did you get a right-angle SATA cable for the Motherboard port? The ones that came with the board seem to bump the GPUs up and they won't sit flush, so I used one of the SATA on the back panel. Thanks for info.

Will this allow me to get past 900Mhz on my XFX 5830 and 875Mhz on my Sapphire 5830? I'd love to get to about 950 on each card if possible.
I use Catalyst 11.6 to drive my 5830s at 990/600 (308Mhash/sec). These are Sapphire cards, your milage may vary on XFX. This is at stock voltage. The commands I use in my startup script are: #Overclock GPU to 990Mhz DISPLAY=:0 aticonfig --od-enable --adapter=all DISPLAY=:0 aticonfig --od-setclocks=990,600 --adapter=${1}
Where $1 represents the adapter # of the GPU.

Other / Beginners & Help / Re: What "speed" should I be mining bitcoins? It seems slow. What am I doing wrong
|
on: July 05, 2011, 12:48:40 PM

I am glad you asked. Been looking for one. The issue is I can only take a single width card. So the question is, what can I get in single width, that will give me 150+, for under $150? Oh yes, it also has to be a current production card.
Why can you only take single-width? Just buy a PCI-E extender cable and mount the card somewhere else in the case. If you're going to force single-width, then just keep mining on nVidia. The double width cards are double-width because the heat generated by the GPU(s) requires additional cooling that a single-width card cannot accommodate. So the only single-width cards you're going to get are going to perform as poorly as your nVidia. Better yet, just don't bother mining. You'd be better off taking your $150 and buying 10 BTC immediately at the exchange. It would take you months and months of mining on a single-width card to generate 10 BTC (probably closer to a year). Then wait for the price to go to $30 again, sell them, and then buy a nice rig.
