Europe - selling an almost new intel DX58SO Motherboard for i7 processors
by
bitk
on 15/10/2011, 01:16:12 UTC
Hi everyone,
I'm selling a barely-used i7 motherboard, the intel DX58SO, good for LGA 1366.
I bought this because I needed a board that supported intel vt-d virtualization technology for testing some things. My "old" i7 motherboard (an ASUS board) did not support that feature, therefore I just bought the intel one for like 240€. Unfortunately, I have had several problems and realized that what I was trying to achieve was rather difficult and... well... I just decided to resign after smashing my head agains a wall for some days.
This motherboard has been used for like 4 days. I can give you a proof (I got a pdf digital receipt since I bought it online on eprice.it) if you want. I can take pictures, videos, whatever you ask for.
It's a bit unlikely that there is anyone even slightly interested in this, but I do hope to resell this hardware since I would like to take some money back on this failure I tossed myself into.
I'm shipping to Europe or America, but America might be slightly more expensive and might pose some challenges (custom duties?).
We can discuss the price, but I understand this is opened hardware, so it's probably worth less than 135€ even if it's "brand new"... Well, let's say it's just tested Wink

If you are still interested but you don't trust me since I have very little reputation (the only trade I did was buying a Credit Card from madhatter's store) we can arrange something on ebay, just drop me a personal message!

PS: there's a 2 years warranty on this board, but I'm not sure how it would work if you live out of Italy.

Approximating 350 MHash per GPU  works out about 15,000 GPU's for the network's ~5 THash/s ... so actually an overstatement.
350 MHash per GPU average? Perhaps you could re-calibrate including the nvidia vs Ati market share ^^
your figure is not so much off anyway, still I think it's quite a big number... when you say "nothing compared to everyday stuff", well, I think there's a bit more than what you think... it's a geeky thing but it's still impressive!

I've started thinking bitcoins have nothing to do with gold. They are more like diamonds, with people having stashes filled with them but not releasing them too quickly or the price will drop really quickly Wink
One thing is for sure, if old bitcoiners want to fix a maximum price, (eg 10 €) they can sell those at that price for quite a long time...

well, I think it might actually be quite the opposite:  a high mining difficulty could discourage people from trying to mine using only their CPUs or "older" nvidia cards (up to 35 MHashes/s), even by joining pools.

looks like the difficulty is gonna drop for the very first time since the creation of Bitcoins? Wht do you think might have happened?
Some collapse of the mining pools, or maybe all the CPU miners shutting down at the same time because it really is a waste of time now? (looks to me that with 100Mhash/sec you pull out more or less 1 BTC in 24 hours right now), or maybe just that some miners are quitting after they speculated enough? General loss of interest?

An arm for mining? You know you are not getting any single penny out of it, don't you? Even with pooled mining...

Re: Mining Probability Calculation and market predictions.

To me, the calculator looks off by a 10% factor or more.
It's expected value is higher of what I get on slush's pool, and since the pool is meant to get your throughput (almost) at the expected value, it's either something wrong with me and the pool, or an over optimistic calculator.
Also, I went mining for about 5 days, with an expected 3 days of payout, but I found nothing. But that sounded perfectly normal to my ears.

Re: Printing bitcoins, an implementation

here in Italy, 100% of the cards for buying phone prepaid credit are scratch cards, instant lottery tickets are scratch cards, etc... I've never heard of someone buying a card that was used and re-printed with the metal layer.
OFC I must say usually you don't buy them from other people but from "commercial entities". Still, if one can quickly check if the money is in the process of being double-spent, this is still way more safer then cheques.

Re: If bitcoin took off, could it fund new investments?
by

Not true, or at least not the whole truth.

Bitcoin is simultaneously like:

1. Cash in the mail
2. Bullion mined from the ground
3. Physical commodity
4. E-currency
5. Paypal

Bitcoin is many things, limiting it only to money transfer is not very accurate IMHO.
Clearly this is invention of a genius, to say the true.

I can agree with 1, 2, 4, maybe even with 4.
But no way I can compare BTC to Paypal! The latter is a service involving digital money: eg, you are offered a buyer's protection program, safer (?) use of your cc online, etc... Paypal is more taylored to fit Ebay's needs, and is not really just about moving money.

Visa has a market cap of 63 Billion.
EBay/Paypal has a market cap of 44 Billion.
Citigroup has a market cap of 142 Billion.

ETC...

So these industries could fall and all of their wealth would be redistributed.  As a whole we would be wealthier.

What you guys don't understand is that bitcoin is NOT a replacement to banks, payment systems, etc.
Bitcoin is the equivalent of cash in the mail, with extra security features.
Think about it: you send a payment, it gets received (confirmed) some time later. (10, 20, 30 mins? still, it's delayed)
The mailmen are the other users generating blocks. They just can't steal.
If you send money to the wrong address, it gets lost. Like regular mail.
Once you send it, you can't get it back, unless you destroy the mailbox.

Would you base the world's economy on mail in the cash?
Personally, I would NOT...
This is the reason for stuff like Visa, Paypal, and others will surely survive.

Maybe one day they will adopt BTC as a currency, but no way they are going bankrupt just because of bitcoins!

bitcoin to prepaid phone credit - Italy only right now
by
bitk
on 19/02/2011, 11:38:39 UTC
Hi everyone! After being a "passive" adopter of bitcoin, now I am willing to enter the market.
I live in Italy and I plan on starting a service for buying prepaid phone credit using bitcoins.
At least in the beginning, I plan filling credit "by hand", mostly at supermarkets or other "physical places" using cash.

For the first test of course I expect people doing little fill-ups, like 5 or 10€ max, but if you insist for a 20/25€ there's no problem for me... Leave a message here or a PM and we will find a deal!

I really hope there's someone willing to try this out.
I'd love to see suggestions coming in this thread, along with your displaying of interest. For "international" phone prepaid credit I need to firstly find out a good way of doing it. Perhaps buying cc from the MadHatter's service and use them to buy credit oversea? Smiley

Ciao a tutti!

Just to inform you, m0m, there is a project (called http://www.compute4cash.com/ which uses your miner only working on their server without any information about bitcoin or any reference to it or your program).  Then taking around 50%.
I know your the miner is Public Domain, but I just wanted to inform you, and potentially tell anyone on the forum that if they see reference to compute4cash, it is really just a ripoff bitcoin pool.

Nice find!

guess you mean a 9600 pro?
Well, no use in mining, sorry. It's missing core features for it to be used for doing work (OpenCL).

Actually, GPGPU doesn't require OpenCL or CUDA, but programming your video card to calculate hashes is probably near-impossible! (and BTW: a quad core i5 is probably faster anyway)

That's a major problem I guess.

Good for us that the bitcoin symbol is gold-yellowish, otherwise we would be in big troubles for the future.

Re: Bitcoin May Be Doomed

I just want to remark that the "OnLive" service doesn't work very good unless you are under optimal conditions (MHO: less than maybe 1% gaming population out there?), and the whole concept of cloud is more productivity-oriented that user-oriented.
AKA: not everyone wants his brain seized for optimal ads.

On a more serious point of view, we have finally the opportunity to use tecnology on our own, without the need for central servers: we don't need old-style terminals any more. Why would one be back to terminals for everything? Including gaming and "personal" office productivity?
If there are people that still think that being on your own is better than depending completely from some central authority, then cloud computing won't be excessively widespread for bitcoin to keep going

I'm under windows! Everything works pretty well right now if I was to be honest, since I'm using 2 different miners, one for CUDA and the poclbm for OpenCL. But having to switch to another miner was soooo sad Smiley I loved the m0mchil one

Hello m0mchil.
I've been using your client a lot lately with a GTS 250 card...
Today I got a new shiny ATI card and I can't use it with your miner, even if they get recognized by software like GPU Caps Viewer! Let me explain...
I got both VGAs on my PC, ofc there's no "Crossfire" or "SLI" since they are from different vendors. The problem arises since the nvidia uses the CUDA OpenCL, the ATI uses (of course) the Stream impementation. This way, my 2 physical cards reside on 2 different cl_platform....
Now, I never touched python in my entire life... but those 2 lines looks... suspicious Tongue

Code:
platform = cl.get_platforms()[0]
devices = platform.get_devices()

I really suspect this is what's giving me problems: I can't see the ATI as listed in the devices I can choose! I could physically swap the cards, or maybe unistall and reinstal all the video drivers so that the first OpenCL platform is the ATI one, but this doesn't really look an elegant solution IMHO Wink
Suggestions for solving my problem are welcome! Smiley EG: patches, or how to compile 2 different executables for windows.
