thanks for the detailed write up now we just need pricing
You didn't read the detailed write-up, I guess:

The pre-order of the batch of 10-15 March is open now at the price of 6200$(the ship fee is included) and the price is 7200$ if you want the miner delivered to you in 48 hours after payment received.


And does the $1000 price premium mean it ships 48 Hrs after you pay so its ready to ship right now? $1000 extra to get it 2 weeks early  Huh

I missed that part at the bottom seems a bit high I see someone on litecointalk.org trying to work a group buy for similar 1TH unit for around $5200 + Shipping costs

I would be interested in 1 unit if we could do a group order and get the price down might take 2 but right now cost seems high compared to profitability/availibility if they were to ship soon ie within a few weeks that could help there value out a lot

My antminer OC to 200GH is pulling 445W at the wall on a seasonic 680W Cold Rated power supply
1148  Bitcoin / Mining support / Re: BITMAIN Antminer support and OverClocking thread on: February 24, 2014, 09:12:28 PM
I had put miners in conditioned datacenter, now I get
0.16 HW errors on older rev. @400mhz
and 0.07 HW errors on newer rev. @400mhz

temperatures on both miners approx. 28C

I think I will try to test overclock them a little more next week

How long have you been running your overclocked to 400? have you noticed any more hardware errors over time
1149  Bitcoin / Mining support / Re: BITMAIN Antminer support and OverClocking thread on: February 18, 2014, 03:13:26 PM
I have my Ant Over Clocked with 375 Mhz Running really reliable and strong

11 hours running Average is 190GH Only 6 Total HW errors I am had tried 400 and got it up over 200GH but way to many hardware errors for my liking I may try a few of the in between settings to try and get it closer to 200GH with less than 1% HW errors I am thinking the 387 setting ill try next

What software do we use once we connect these up to windows.  I got my PSU so that's ready to go.  Do we need the controller?

I believe its just a modified version of cpuminer and they hook up via USB cable to your pc or with a USB hub if you have multiple units

Likely will bump my order up to 3.  Just awaiting status update.

Status update as in what kind of update?

Like this?
Batch 1 Units should be to me by the end of next week.
Yes i know "should".. BUT Here is some BETTER news. They are being currently held due to making sure the firmware upgrade is all good. So The rumored 500-600kh/s is true. Shocked Cool Sorry for the delay.

This is good news  Grin
I cant wait to play with my new toys !!

I know a lot of people say you need a decent amount of memory for scrypt mining but I still don't understand why. If I look in taskmgr I see cgminer taking up ~55MB. I am using two 290's. Thoughts?
A lot of people are clueless. I have 5x 290s per mobo with 4GB of ram, and never had an issue.  2GB of ram should be more then enough for a linux miner.  That said, the distros like bamt are messed and seem to eat RAM, but my gentoo installs have 90% free memory no matter how many cards are installed.

The Asrock BTC boards will run 5 or 6 R9 290s no problem.

With less than 3-4GB or a 32bit OS, you can run into issues  - "Error -5: Enqueueing kernel onto command queue" when attempting to start cgminer.

There are brief periods of large memory allocations and CPU for the Xorg and cgminer processes.

I saw this when I built a 6x rig and was using 2GB of RAM since its what I had laying around.  With 2GB, all sorts of issues.  With 4GB, no problem.



I agree with the new cards I had to have 8GB of RAM with 2 Cards or CGMiner would crash with the enumerating kernal error. On your Multi card Rigs are you using regular CGMiner 3.7.2?
1153  Alternate cryptocurrencies / Mining (Altcoins) / Re: Asrock H81 BTC Pro Board and Sapphire R9 290X Tri-X on: February 10, 2014, 02:21:54 PM
I have multiple rigs running 2 X 290X Cards all hitting 980KH for some reason on my 4 card rig with mirrored settings I can only get 710KH per card I thought it may have had to do with the ram so I upped it to 16GB no change I suspect its an issue with the thread concurrency being different with 4 cards then it is with 2. If anyone has any insight into this I would greatly appreciate and if it helps id me happy to donate for your support Wink

What is the hashrate for one of those?

300khs but new firmware is being tested and has reached 500-600khs

OOOOoooooOOOOO kinky.  Shocked Cool

See and some feared being an early adopter was foolish if the hash rate can double with new FW then I think a lot more people are going to start wanting them Smiley

I am curious on your 5 card rig what are you getting per card? Do you ahve the 290 or the 290x's? What model card?

sounds great, I ordered a 5MH/s miner from alpha-t - but this looks like a good alternative

/follow Grin

I also pre-ordered one I am in batch 1

Quick update

Asked Asiabtc about the CE mark, hope they will reply soon.


There is but your pricing is better and there group buy is limited to 2 units
My pricing is not for competition...

Ok I will order from the US Group buy then

If the GBO of your region allows, then I am fine with you joining us. However, this group buy prioritizes EU buyers first.


I spoke to the organizer of the US group buy we can do up to 5 Units so I will join them for now and save on the shipping, But if all goes as planned I will order more soon. Thank you
