2  Economy / Auctions / [EU only]10 x ~5Mh/s Scrypt at 180W. Starting bid 950€. Silent and Stable. on: April 18, 2014, 05:51:43 PM
Hello Everyone,
i wanted to try something new and came now up with the following idea:

What you get:
The possibility to get the fastest and cheapest Gridseeds on the market probably remanufactured with best possible quality.
Each Unit will hash with at least 494kh/s and some will also be able to go even higher as i use high quality thermal pads to increase stability dramatically.
Also will each units fan ground rail be soldered to the 5V USB GND. That means Silent Fan, with NO EXTRA powerdraw on the 5V USB Rail.
Powerdraw per unit is 18W and for one package 180W.

You bid per package and one package includes ten miner units with an Hashratee of ~5Mh/s.
Bidding style: 1@950€ for example means (one package at the price of 950€).

Highest bid wins all the time. For Example: A says 10@950€ and B says 1@960€ then A will get 9 packages and B will get 1.
Auction will be done in € and biddings will be converted to BTC at the end of Auction.

Preparation time from day of payment till day of sending will be 5 days.
Shipping inside of Germany 6,99€
Shipping inside of EU 16,99€

Amount of bidding will be exchanged to Bitcoin and being paid directly after Auction.
Exchange rate: (Kraken BTC/EUR).
If you take more than 6 hours to pay, the bought articels will go to the lower bidder.


Proof of how they work stable > 24h.
(Shows only units with offered modification.)

You get silent and stable ~5Mh/s modded with best quality and head for little more OC at 180W
Starting bid: 950€
Lowest increment: 5€

Auction ends at 21.04.2014 at 18:00GMT.
3  Other / Archival / 10 x 4940kh/s OC Gridseeds for Sale. Silent and Stable! (scrypt only) on: April 18, 2014, 05:02:54 PM
Hello Everyone,

i wanted to try something new and came now up with the following idea.
What i want:
A little income for my further studies at the university
What you want:
Cheap, stable and fast working Gridseeds
What you get:
The possibility to get the fastest and cheapest Gridseeds on the market probably remanufactured with best possible quality.
Each Unit will hash with at least 494kh/s and some will also be able to go even higher as i use high quality thermal pads to increase stability dramatically.
Also will each units fan ground rail be soldered to the 5V USB GND. That means Silent Fan, with NO EXTRA powerdraw on the 5V USB Rail.

So in short: 4940kh/s per package, all fans being silent and due to best thermal solution head for overclocking to about 530kh/s.

Proof of how they work stable > 24h.
(I only highlighted the Units which i did with the mods i will actually do with the Units offered here.)

4  Local / Biete / [WTO] Gridseed Moddingservice: OC+, Silent Fan, Stable mod on: April 10, 2014, 04:04:40 PM
Hallo liebe Forenuser,

aufgrund mehrmaliger Nachfrage will ich nun einen Moddingservice von Privat zu Privat anbieten.
Ich würde drei Modifikationen durchführen die ich wie folgt benennen werde:

- OC+:
Durch erhöhung eines Vorwiderstandes wird den Chips eine höhere Voltzahl bereitgestellt. Dies lässt ein Übertakten bis 1150mhz (489kh/s) zu.
Wattverbrauch der Einheit liegt dann bei ~ 18 W.
- Silent Fan:
Die -12V Leitung des Lüfters wird über den 5V USB_GND abgeführt. Dadurch fällt bei dem Lüfter nurnoch eine Spannung von ~ 7V an und dieser dreht wesentlich leiser.
Vorteil dieser Lösung gegenüber einem Widerstand oder eine direkte anbindung des Lüfters an die USB Leitung ist, dass bei dieser Methode der USB Port keine weitere Belastung erfährt.
Leider sind die verlöteten Bauteile größentechnisch etwas unausgeglichen, was das Umlöten etwas zeitaufwendig macht.
- Stable Mod:
Ersetzen des Standard Kühlpads durch nichtleitende Wärmeleitpaste, zur Verbesserung der Wärmeabgabe.
Durch die verbesserte Wärmeabgabe bilden die Chips keine Hotspots und arbeiten wesentlich stabiler / effizienter.
Minimiert Hardware Fehler.
[Bild folgt]

10€ pro OC+
2,5€ pro Silent Mod
1,5€ pro Stable Mod

Akzeptierte Bezahlungsmethoden: Bargeld, Litecoin und Bitcoin.

In-Stock Proof:

Units Hashing Proof:

I will add a more long term stable proof the following days.
But for now the results are looking very good. Also the soldering is very good. We already achieved 420khash/s with very few HW-errors (negligible).
The applied mod is this one : 2-Pin Bridge mod

Gridseed @ 350kh/s and 850 mhz, Not Modded unit

Gridseed @ 400kh/s and 950 mhz, Modded Unit

Power Draw:
Be aware that this is the overall Powerdraw.
I've got a really messy psu working here it should be around ~82% power efficiency or less.

Gridseed @ 350kh/s and 850 mhz, Not Modded unit
Overall powerdraw: 9,8W (8,036W Gridseed device, 1,764W PSU)

Gridseed @ 400kh/s and 950 mhz, Modded Unit
Overall powerdraw: 11,1W (9,102W Gridseed device, 1,998W PSU)

Without fans the power consumption will go down further (roughly 2W, updates will follow) - a fan in litecoin-only-mode is not needed (safe).

Tax? Customs?
Order within the EU or UK and there are no taxes/custom duties or whatsoever to be paid.

Things what will follow shortly:
- Adding Payment method.
- More detailed explanation of different things
- 420khash proof
- usb cables

8  Alternate cryptocurrencies / Altcoin Discussion / [DOGE Pool Project] Software advise on: December 23, 2013, 12:57:03 PM
Hello Guyz and Girlz,

i'z want to setup a doge Pool.
I aim it to be the much wow, most amaze, very support and main profit pool to be.
(*serious mode on*)

I want to open a Mining Pool for the new Dogecoin. The goal of this is to provide a stable and efficient mining pool. Server hardware for this project does exist and i know of some mining software, to set up things, for Bitcoin for example. I for myself really do like the Eloipool software for example. But when it comes to the scrypt coins i do not know much about.
I do have certain programming skills and can do some for my own, but i do not want to create the wheel new.
I also do know much about Linux and i am fully able to set up them in a safe way to hgihly reduce the probability of being hacked or ddosed.

Is there any software you could provide me with or which you could advise to use for me ? Have you probably done something like that and can give me a little tutorial on how to go with something like that ?

My favour would be to take the Eloipool and modifiy it to work with the Dogecoin. But as i did not program the pool software my very own it would possibly take a large time to do so. Which i prefer to use on making it more safe and reliable instead of building the basics.

I really do appreciate your help a lot.
