1  Local / Mining Discussion (Ελληνικά) / Με τόση τύχη, πάω για τζόκερ! on: February 29, 2016, 06:07:21 PM
Ο miner κάνει φέτος το  θερμαντικο κάποιες ώρες της ημέρας αφού καίει τετραπλάσιο ρεύμα όσα BTC παράγει.
Αλλά σήμερα η τύχη μου τις ώρες που τον άνοιξα και τον έκλεισα ήταν για να πάω να παίξω τζόκερ!

3  Local / Ελληνικά (Greek) / Η Coinbase τώρα και στην Ευρώπη. on: September 13, 2014, 05:10:32 PM

Τις πύλες της Ευρωζώνης ετοιμάζεται να περάσει η Coinbase, μια από τις πιο φιλόδοξες αμερικανικές εταιρείες bitcoin.

Η εταιρεία συνέδεσε μια υπηρεσία ηλεκτρονικού πορτοφολιού bitcoin στο σύστημα πληρωμής με ευρώ, καθιστώντας δυνατή για τους χρήστες την ευκολότερη αποστολή χρημάτων από και προς έναν λογαριασμό bitcoin στις δεκατρείς από τις δεκαοκτώ χώρες της ζώνης του ευρώ, περιλαμβανομένης και της Ελλάδας.

Με άλλα λόγια, ένας καταναλωτής στις χώρες αυτές θα μπορεί να αγοράζει και να πουλάει bitcoin μέσω της πλατφόρμας της Coinbase. Το project βρίσκεται ακόμη σε δοκιμαστική φάση, επομένως το ημερήσιο όριο συναλλαγών ανέρχεται στα 500 ευρώ.
4  Other / Politics & Society / Helping the PP of Greece print 14Μ ballot papers. on: March 03, 2014, 06:41:34 PM
The PP of Greece (established 2 years ago scoring 0,51% in Greek elections)
has launched a croud-funding campaign to get the needed 35 BTC or 1500 LTC
in order to print ballot papers for the next European Parliament Elections in May.

(in Greece parties are required to print and pay the ballot papers and shipment-delivery by their own means, there's no state funding for small parties)
In case this amount is not gathered by the end of March, they won't be able to participate.
If the final amount is not gathered and the party doesn't make it to the EU elections, you may request your coins back.

Here's a brief of the core PPEU ideas http://elections.pirateparty.gr/?page_id=477

Here's a European spot made by the PP of Greece http://www.youtube.com/watch?v=_P7l8j7Yw5w

So, if want to promote the Pirate Ideas, please help at the BTC & LTC addresses mentioned here:

5  Other / CPU/GPU Bitcoin mining hardware / SAPPHIRE 7950. low fan speed (suddenly) on: January 23, 2014, 09:09:10 PM
A 10 months old SAPPHIRE 7950/3mb card has suddenly decided to slow down the fans!
They're both working (rotating) but even at 100% fixed, they're giving barely 2500 RPM instead of the usual 3000+ (I don't remember exactly).

As a test, after setting manually the fan at 50% they were around 1200 RPM. Of course the card is overheating and I set her back to 925 Mhz core, 1250 mem, just to run at 71 degrees C.

Any thoughts? Has someone had the same experience?


PS: Fan noise is also much lower now Wink

Hi!

I'd like to sell one unique coupon code that I got together with my AMD card, and I don't intend to use.

The highest bidder on June 21 2013, 15:00 UTC, will get the code. Bids of course are in BTC.

Here's the coupon (code and barcode pixelated).


7  Alternate cryptocurrencies / Altcoin Discussion / cgminer, 7950 and scrypt on: April 29, 2013, 06:26:04 PM
Hi!

I'm trying to test Litecoin mining using a SAPPHIRE 7950 3GB, but I'm getting no more than 410 kh/s instead of expected 600 kh/s

Intensity >16 leads to unstable system crashing
thread-concurrency > 8192 is not working
gpu and mem speeds can go higher but don't increase hashrate
I've tried --shaders 1792, nothing spectacular happened.
OS is win7 64bit, 8GB RAM, CPU i5-2310@2.9Ghz, GPU temp around 63 Celcius

Here's the batch I run:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer -o http://POOL:PORT -u USER -p PASS --scrypt --intensity 15 -g 1 -w 256 --thread-concurrency 8192 --gpu-engine 1000 --gpu-memclock 1350

Any suggestions? Can you post your working settings and speeds?

Thanks!

Update 1
NEW WORKING SETTINGS, still at 400 Kh/s
--scrypt --intensity 18 -g 1 -w 256 --thread-concurrency 21712 --gpu-engine 1100 --gpu-memclock 1600 --gpu-powertune 20 --lookup-gap 2


Update 2 (see below)
Better settings for me so far giving 575 kh/s

--scrypt --intensity 13 -g 2 -w 256 --gpu-engine 1095 --gpu-memclock 1475 --gpu-powertune 20 --lookup-gap 2
