Technobit Hex8A1 Coincraft in hand.

[loshia]

Morning fellows,
My board PIC FW and heat sink and fans were upgraded yesterday. What I can tell you it rocks. Here are my results after 14+ hours nonstop mining


Some things to point out:
1.   My stats are not settled yet, because I am mining at 512 diif + filtering out nonces inside ASIC chips  which do not meet it. The board is making 270GH stable and there is some room for overclocking. BUT I do not feel brave enough to do it and I suggest to all of you not to push it too much.  We are hiiting the limits of hardware especially voltage regulators so overdriving them for a long period is not good idea at all. This is my personal opinion.  I do hope that there will be precise measurement of power consumption very soon. I am using single rail psu rated 55A/12V. I think the bottom line is at lest 45A, to be on a safe side
2.   Tplink+cgminer worked rock stable without an issue. My pool reject rate is 0.12% only which is golden! I am not commenting my HW error rate at all Technobit team did their job just perfect
3.   What I can tell you that all of you should be able to get the 260Gh advertised at clock around 260 and voltage around 1000 mv. You have to experiment a little bit to find your sweet spot though.  
More updates to come  

loshia what are the temps being reported back?

No temp sensor on the board dude.
But it is getting hard to touch if not cooled right
I would say up to 25 maybe 30 celsius you will be ok with stock fans an heatsink. My room temp is not more than 15 because of the winter so cooler is always better

Good to hear. We keep our "mining room/datacenter" at about 18c but I heard these things need some space to themselves.

how much you want for the miner? 1,4btc

how much you want for the miner? 1,4btc

First batch (only 30x units) cost €1,500
BTC right now = €511

I don't think anyone will part with one for 1.4BTC = instant loss.

I know you're hinting we could have bought an AntMiner, but AntMiner was 1.95BTC and BTC was €615 when these orders were taken.
Back then it looked the same $/GH, but with better GH/W, but sadly not now, such is the risk of buying on specs.

I was curious what kind of heatsink upgrade

New image for TL-MR3020 + cgminer 3.12.3 patch 0.2.0 Milestone release

New image for TL-MR3020 + cgminer 3.12.3 patch 0.2.0 Milestone release

Do I need to reset the TL-MR3020 back to factory settings for it to install?
If so how, do I do that?

Thanks.

Hey,
Read the change long
Use *sysupgrade.bin for openwrt preflashed router or *facory.bin for factory FW router. As i call it a virgin one
Short answer no, but after you install it go to web interface cgminer configuration andfeel all blanks with default values quoted and Save+Apply

No need to reset, just browse the new image & hit flash  
But i usually use factory bin, i am prefer "fresh install"

Sorry, Dude,
I just had the chance to do it :

nice toaster! =) *where can i get one?

Got mine today, working perfectly, stable 260Ghs on a tl-mr3020 with patched firmware and default settings.
But this thing is incredibly noisy ...
