Hi

Just wondering.... if overclocked, thinking of adding another fan, any idea if it's better to have it sucking or blowing at the other end of the frame?

Slash

I installed a second fan and having it move air in the same direction as the existing fan, i.e. blowing out. The hot air appears to be moving faster and the antminer is stable at room temp.
I put one fan in the front sucking the warm air out just as infamousdutch did. Temps are stable and hashrate is stable and I feel a bit safer with more air flowing through the device. You can use the power connector on the second mining card.

Confirmed, using 375 MHz and 37 timeout is hashing at about 200 Ghash/s
        option 'freq_value'     '4e81'  #375M
        option 'chip_freq'      '375'        
        option 'timeout'        '37'

interesting that 400MHz gets the same speed then...?

also, i tried the 425MHz code and was getting around 185-190GHash and semingly more errors, so i backed off to 400
Yes,  over a few  hours the did  close  to 200 with both frequencies.

Yep, already seen...
but it'd be nice to replace the avalon 130nm boards...

Hi, what's the future plan for avalon now?
BITMAIN has sold over 100 Units probably using Avalon2 chips and they run quite well. (https://bitcointalk.org/index.php?topic=355755.0)

@ProfMac
I'd appreciate mining cards to replace the 130nm cards in my Avalons. This would be just perfect for all Avalon users, because they could use their old devices and parts like PSU, TPlink and case with the new cards. Do you think this is possible?
As far as I undestand it, a similar working card like the ones in the first gen avalons could do around 4 times more than the old ones with the same energy consumption. An Avalon Mini would have 240 GHash/s and an Avalon with 4 cards even 480 GHash/s. This is almost the power of a KNC Jupiter with around 2 W/GHash
Please correct my if i'm wrong!

The mining plan for an Avalon Mini could look like this:

Ok, thanks for the info. Now it could be tomorrow the units arrive. Nice.

Hi, i'm not concerned that I don't get the product, but I want to avoid lags in the german customs process. With a valid tracking number I can inform the customs service about an arriving mailing and accelerate the process. That's the only reason why I'd appreciate a tracking number.
19  Economy / Auctions / Re: The 3rd Round Auction for the AntMiner S1 Dual Blades, 120 units, 24 hours on: December 08, 2013, 11:57:57 AM
I didn't hear anything yet. Unfortunately UPS myChoice isn't working with german addresses.
I'd be happy to get a tracking id...  Wink
