Current cost is $420 at time of transaction. I'm not going to set a BTC price because every time I do it changes. Honestly I should have done that from the start. I can get one from Bitmain for $373 shipped, plus reshipping within the US and a bit of work and testing. I'm using some of the overhead to buy a spare miner or two in case something doesn't pass muster, which is always possible.
Round one has arrived and are currently running smoothly. Round 2 are in transit, hopefully to arrive tomorrow. I'm okay with a Round 3 if folks want to start chipping in. I'm starting them out at 620mV cold and running 450MHz (2TH, ~420W); any boards which aren't stable at 620 get bumped up to 630mV. Any boards not stable at 630mV get rejected. So far I've had two boards out of 16 not stable at 620mV, and one appears to be stable at 630mV.
If you specifically want a different setting (say, optimized for a specific hashrate or power consumption) let me know and I'll try for it.
All the miners are testing pointed to Eligius on the 1ColdS7 address so anyone can see how they're behaving.

This is good news. When I get mine I will post a review and show how much improvement can be done with a titanium psu. I may also try replacing fans with these. https://www.amazon.com/Silverstone-Cooler-Computer-Cooling-FHP-141/dp/B00A460TK6/ref=sr_1_1?I think these will use less power then the stock ones.

I changed the price to $420. I got to thinking about it, and the $430 I'd set was for a guy using PayPal. Their fees would end up eating about $20 off that, so adding $10 splits the fees evenly between me and the buyer. Course adding $10 also incentivises buyers to use BTC when possible, which is handy because Bitmain doesn't take PayPal and the coins for the order have to come from somewhere.
Looks like Round 2 units are still sitting in a DHL warehouse in Ohio, where they've been since Saturday night. I've already heard from them and given them updated customs info and expected to see the truck this morning but according to tracking they're still in Ohio. Sorry, batch 2 guys. I'll stick with UPS for shipping. The prices between the two weren't that different, and I wanted to test which had the better service. I've received express packages from China in under 30 hours (even account for time zone differences) via DHL before.

Hey Sidehack, Is this a hardware mod or a firmware mod??
I've already purchased a S7LN & its sitting in my countries customs office but should be delivered later today, I dont wanna have to resend to you & get it back again, So i was wondering if i could tip you for a copy of the modded firmware if possible??
If its a hardware mod, then im outta luck till a firmware mod comes along i suppose...
Let me know please..
I seem to remember somewhere here in this thread you were going to charge 0.05 for the mod, I'm more than happy to do that, U do great work for this community..

Check the thread in the hardware section (hint - link's in my sig), which has instructions, pictures, and downloads. It's modifying firmware on the hashboard itself, not the controller, so you'll need to acquire a PIC programmer to do it. All is explained in the hardware thread.

It's a shame it's only within the U.S. I could do with a quiet miner at around that wattage

If you want to cover postage from me to you, knock $20 off the GB price and send me a shipping label. I just didn't want to have to mess with bidding international transport and customs paperwork and using whoever's favorite carrier this week.

I'll cover the postage cost for it. Not quite sure how I'd send a prepaid shipping label to you but I can cover the customs cost this end. What would the price be all inclusive? It's only I'm running three rboxs and two gekkos off a raspi and they are pulling 420w at the wall (365ghs).

A shipping label can be created online and emailed to me.
Current cost is $420 BTC or $430 PayPal (to account for some of the fees they like to add). So if you're sending a label, $400/410

Cheapest I could find was £130 for shipping But I'm having trouble getting a definitive quote. Have you got a location, zip code no weights and measurements of the package? I'm sorry for all the hassle, I'd just like one as it fits exactly what I need

Probably cheaper at that point to just track down a PIC programmer and learn how to do it yourself.

once again I may be able to help. I am doing one for HagsFinn.
Sidehack is shipping it to me in NJ I am pulling the psu and shipping it powerless to HagsFIN
This would mean you need a psu from your country GB.
I gave HagsFINN a credit of 70 usd for the psu and he would pay me about 45 usd since shipping is 115 usd to Finland. I may be able to this for you.

philipma1957, if need it shipped complete if possible (if all the pci-e cables are required) I don't mind paying for the extra weight. That's a damn good price for shipping to Finland.
How would we go about sorting this out? Would I sort it out with you direct and you have another in order with sidehack?

If you want to work it out with Phil, I'll just ship another unit to Phil at regular price (420/430) and you two can iron out the details however you want.
I'll post package dimensions here in a bit, once I start repacking the ones going out today.

Got mine ~2 hours ago. Works as expected with a solid 2TH and no errors on Eligius. I did have to hard reset after changing the pool info and fan speed; but solid since then. Nice and quiet.

Yeah, that's about the only issue with a hot/cold cycle with the cold-running voltage that close to bottom threshold, is you really have to already be mining stably by the time it drops to cold. Cgminer restarting at cold voltage will probably drop out one or both boards so a power cycle is recommended (very likely required) after setting pools.

Yeah, customs hangups. I got it squared away this morning but, even if it had been in time to make the truck, I wouldn't have been at the shop to receive them. Units should be in my hands tomorrow morning and going out Thursday afternoon. Sorry about the delays.
