I just wish the thoroughness didn't come at the cost of time that's already been lost due to customs and delivery hangups. Nothing says "expected delivery June 21st" like packages showing up on June 30th, after something like 3 emails and 5 phone calls to the carrier.

No worries @sidehack those are things beyond your control. When things are under your control you are doing what you think needs to be done, and letting us know. That always wins in my book.

Cheers,

How perculiar. The room I'm going to be keeping mine in as always around 20c so hopefully be ok.

Oh right, I keep forgetting that most people don't work on major holidays.

Also, some of the already-proven-stable miners dropped a board this morning, I think because the shop cooled off unexpectedly (lots of rain). I remember there being talk about the stock S7 having a "sweet spot" for temperature, below which they weren't stable, so I'm blaming it on that. And then turning the fans down manually.

So most of the miners dropped at least one board overnight, which means stepping up the voltage and re-testing. I want a solid day at speed without dropouts before I'll ship, which probably means Monday. I'm not sure why this batch is so much more finicky than the last one; luck of the draw I guess. After initial tuning, none of the last batch failed overnight; this time most of them did.

Not likely on Monday, the 4th of July.

According to the pool, all the testing miners have been running solid all day - that's pretty well 12 hours for most of 'em. Hopefully they stay solid and I don't have to mess with 'em any more and can get 'em all out on Monday. Again, sorry for the delays but I'd rather spend an extra day making sure something's right than have to fight with back-and-forth to fix problems later.

CrazyGuy - glad to hear it.

My round 1 sidehacked S7LN has been running perfectly for the past few days. Great work Sidehack!

No worries. It's got to be what it's got to be voltage wise. Really appreciate how thorough you're being with these miners.

As of now I have 8 workers all firing. The best seven will be sent out to cover round 2 and gt_addict from round 3. I figure that'll do it and then this'll probably wrap up. Phil, at least one of the miners headed to you will not have an attached PSU on account of I don't have that many I trust and you'd be taking them off anyway. I'll make sure it gets made up to you if I get some warranty replacements out of Bitmain, which I certainly hope to do since part of why I bought one in the first place was to get the PSU for other things but after this buy is taken care of I'm left with only dead ones.

Round 2 miners arrived just a bit ago. Got 'em all up and running on stock settings to make sure they're good. Barring earthquakes I should have 'em worked up, tested and dropped off at FedEx tomorrow by cheeseburger time.

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.

Any news about the round 2 miners?

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.

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.
