Liquid Synergy Designs Inc. -ASIC mining hardware

So I got good news for Steamboat. I went and collected the miners even if it takes a year to make back the VAT I had to fork out.

Anyway, back home I opened the miners and disover the... invoice... ok, more on that in a bit.

I also discovered a bit upseting thing, namely that two of the 5 miners had thermal goo coming out of thru holes or vias all over the PCB. These two units weren't
packaged in the pink styrofoam (pink styrofoam == non static generating) but regular white packing styro... this styro can make several Kilovolts during transportation... not good. (It may be antistatic too, but I've never seen it in white colour)

Back to the invoice again; Turns out the VAT I paid was for units costing 133 bucks a pop (that included testing) while the assembled but non tested units afaik was 95 bucks a pop.  So when I told SB to send my miners as is, he still put on the package the price with testing...

So now I got 3 miners hashing away (soon... setting up software) and 2 miners I don't dare plug into any electricals until I figure out if they'll even work... with all the goo mess and static discharges they may have been victim to.

What you guys think?

That thermal grease should be non-conductive, so no problem with that.

Hmm... okay, so no silver in it yeah?

I'm a bit lazy so I've not checked this myself, but are there thermal vias for the buck reg, or is the hot face up from the board, rather than down thru vias like the avalon chips?

Ok, measured the resistance of the compound, and it turns out to be non-conductive. Firing up them babies too then.

And they're working

Hey Steamboat, just checking in to request an update on assembly refunds. Unlikely you will respond soon, but just pointing out that no one has forgotten.

Now that you have things going again, please spare a thought for those of us who placed our trust with you for the assembly.

I would either like a refund or if possible I am also open to using the parts with 55nm chips if this is possible

Can someone catch me up on what's going on?  I lost track since the forum was hacked.  I was in Batch 5 and asked for a refund but never got one.  I don't think I'd want one now since I paid in BTC.  Is steamboat shipping or are we still waiting for a finalized version?

[TracerX]

It's crazy actually holding this thing in my hand, after all the work SB put into it.  It's extremely well made, and the packaging was flawless.  Thank you guys so much, I know you all went out of your way to make this happen.

Now to go plug it in....

You prolly are after the refund cutoff.  2 batches were shipped and received from YIFU.  Miners are still being developed. (actually just the bootloader thingy)  If you want your units shipped as is (before bootloader completetion) then you have to send him an email.  Otherwise you can continue to wait for your units.


Personally, I already received my units as is and don't understand what future firmware could possibly due since mine are mining exactly as expected, if not better.

Received mine this morning, hooked it up and I am getting this:

The actual mining that is being done is with my 7970, can't get the Klondike working. What am I doing wrong?

Here's my config:

Code:

{
"pools" : [
	{
		"url" : "stratum.btcguild.com:3333",
		"user" : "cmorris14_1",
		"pass" : "123"
	}
],

"failover-only" : true,
"klondike-options" : "300,50"
}

I'm not a windows user anymore but it looks like you need to install the winusb driver, I'd mine from linux personally since its more secure and has better uptime stability

Found it and it's running well now.
~4.5 Gh/s average (over 5 minutes) @ 300MHz. Will be tweaking it later tonight.

I have a Silverstone Strider Essential Series ST60F-ES, it has 4 PCIE connectors, if each PCI connector has only 75W and each klondike uses 60W wont I be able to only use 1 per connector rather than split each connector?  I thought originally each Klondike would consume 32W, but steamboat says the F16 uses 60W.  Any advice on this? Will I be able to power 8 K16's with this power supply or only 4

The 75W rating is exceptionally conservative. You are fine to put two Klondike per PCI power line. You should be able to do 8 with no problems on that power supply.

[cp1]

That power supply can only put out 500W at 12V, so 8x60W will be cutting it close.  If the PCIE wires are too thin to carry all your power you can just take it off the molex connections too.

Each PCIE 6pin cable can supply 150 watts,so you can connect 2 per cable.I am doing just fine with 2 per cable on a 450 watt PSU:

One of those 4 connectors is a 6+2 pin, which is designed for 150W. Assuming they use the same gauge wiring on all the cables, it should be safe to pull 150W from each 6-pin's as well (both 6 and 8 pin connectors use only 3 positive wires). Though I suppose the PSU's internal connections could be poorly designed. The PSU can do a total of 500W on the single 12V rail, so I'd say you can probably run 8 K16's without problem.

It is so utterly utterly frustrating to look at this thread.  I applied for a refund but apparently missed the deadline (that was never communicated).  I paid to have my miners hosted, so now I'm watching people who have decided to have theirs shipped receive them and start mining with them.  I don't understand why the hosting is not being sorted out sooner when clearly these units are working (to some degree) already.  I know they are next to worthless now - perhaps this is why SB is dragging his heels on getting the hosting set up...

If you split each PCI-e power connector only once, you should be able to power 4 miners off of two pci-e connectors coming from your PSU.
You can also use molex->pci-e adapters and power more miners that way.

For 8 miners you should use a 650W 80Plus rated (Bronze,Silver,Gold etc) powersupply (will put you at about 50% load for max efficiency when hashing)

Incorrect. The terminals are rated for 75W each (72Watt actual), this is why a 200W graphics card will have 2x6pin connectors for 150W plus the 75W from the PCI-e slot (~225W)
and 250W cards will have 8+6pin (the 8 pins (8 and 6+2) are rated for 150W, 6 pins are only 75W (72Watt actual)).

Edit: there are 8pin to 2x6pin splitters out there, which would be fine to split twice for use with Klondikes (4xKlondikes per 1x8pin branched out).
