1  Alternate cryptocurrencies / Mining (Altcoins) / GPU not recognised on CrosAir pro cables on: April 10, 2014, 06:26:20 PM
I have Chieftec Navitas 1000W PSU that has only 2 common GPU outputs
http://www.chieftec.eu/en/psus/navitas-serie/gpm-1000c.html

I want to connect additional GPUs via molex but with PSU I got only 1 such cable. And I couldn't find anywhere CHieftec spare cables.
So I've purchased CorsAir Individually Sleeved DC Cable Kit
http://www.corsair.com/en/professional-individually-sleeved-dc-cable-kit-type-3-generation-2-red

GPU get both green lights, turns coolers but neither BAMT nor Ubuntu recognise the card on which I try them, I've tried card restart with cables, doesnt work, but the power doesn't seem to be an issue?

How can I trouble shoot the issue?

GPUs are Asus R9 270x DCII Top OC
2  Alternate cryptocurrencies / Altcoin Discussion / Historical/current prices API for major pairs on: March 21, 2014, 02:43:29 PM
I am trying to use historical and current data for major alts and so far I managed to obtain current prices via cryptsy API.

However, I want to be able to get historical ones as well.

What APIs do You use for this?
3  Economy / Services / WTB Get an item on ebay on: February 28, 2014, 07:58:47 PM
I am looking for these particular cables, and can't find them anywhere except on ebay, but my country doesn't have paypal.

http://www.ebay.com/itm/Hybrid-Modular-Cable-System-Cables-from-Antec-True-Power-Series-/320836206492?ssPageName=ADME:X:AAQ:US:1123

They cost 5$, I'd get like 4 pieces and pay in any coin, escrow would be really nice. + I'd pay for the service, seller is located in UK, and I am located also in Europe.

Would anyone help out?

5  Other / CPU/GPU Bitcoin mining hardware / [Help]Connect 3+ cards to PSU w 2 vga outputs? on: February 19, 2014, 05:09:35 PM
I am first time mining, and so far I managed to mine with 2 cards at 410Kh/s, my setup is:

BAMT 1.3 on USB
Gigabyte 990FXA UD3 Rev4
4 Asus 270x DirectCUII Top (oc edition)
1050w Chieftec Gold PSU
AMD FX4600
8GB RAM

The issue is that PSU has 2 VGA outputs (http://bit.ly/1blRwMu), so I connect 2 cards easily (http://postimg.org/image/ifxnx36ap/), but could I utilise the black outputs for more cards somehow?
Or can I use these cables that came with cards so that I plug one of these and one from vga output, and get 4 cards to run on 2 red outputs? ( http://postimg.org/image/jps9q9bnl/)

Cards take ~180Wx4=720, I have AMD FX4600 that takes additional ~150, and I still have some left, am I right about PSU being able to run this?
6  Other / CPU/GPU Bitcoin mining hardware / Got 1st rig. Need a bit of help on setup, cards and risers? on: February 03, 2014, 05:11:52 PM
I've just bought my first mining rig, and I need help a bit of help:

- how to setup cards/risers? Which types? How many powered/non powered? USB risers or not?
- do I need cooler for CPU? Passive cooling for rig? Small or large ones? (I will test it, but like a guideline?)

4x ASUS Radeon R9 270X DirectCU II
http://www.asus.com/Graphics_Cards/R9270XDC2T2GD5/
1x GA-990FXA-UD3 rev.4.0

1x Kingston 8GB

https://bitcointalk.org/index.php?topic=7216.msg4896733#msg4896733

What do You think of setup? And what to do to make most out of it?
I know its nothing special, and PSU could be better but its a start. I might process some data with it, thats why I got 8GB and avg AMD.

Would appreciate a bit of feedback as I am overwhelmed with all the info and sorts of tech.
7  Economy / Economics / Commercial-centralized system based on blockchain-like transactions? on: January 12, 2014, 08:59:35 PM
Considering on one end eminent rise of distributed systems, I feel that one may not overcome the vast majority of people who are currently and continuously (depending on how You see it) allowing others to lead them, chew the thoughts, ideas and knowledge for them, get celebrities to design their lifestyle, etc while on the other end considering the rise of alts and the ease of cloning either Bitcoin or one of the scrypt's while valuing itself for the protocol rather than the bubble, are there already systems servicing communities other than those familiar with Bitcoins based on blockchain or idea in any way?

How soon do You expect commercial-centralized system to be based on blockchain-like transactions?

eg. A local bank issues a clone-coin, only its branches are allowed to mine and uses network for internal transfers. Parses a blockchain to overview their whole internal network, while they work on a backend to use regular banking systems for outside transfers?
