New Official AMT Thread

[ladi4ever]

At least we are getting the promised hashrate. If it works and its a proven design that is known to work then whats the problem?

No problem with that.  But see the other thread...

Generally could care less what goes on there. ck is just miffed so many folks use cgminer and he gets near nada from it.. Now if it is a reminder to trolls that if they want post to remain, the users thread is where they belong, fine. Gee, Bitmain, Spondoolies, BlackArrow, TechnoBit, etc all moderate/delete posts. Their thread, their rules. So what?

Ja, BitMine.ch seemed to have no idea of the pitfalls in birthing a complex power design. JoshCo definitely had no idea and relied massively on what BitMine gave to them. Wildly over promised on many levels? Damn right. Horribly executed. Double damn right.

BFL - after their 40nm chip release, dumbfounded there. To me the technicals needed to safely push the Monarch chip should have been obvious. And should have been addressed in later revs after working ones on the comparatively low original spec hash rate were sent out.

In all cases regardless of chip/miner mfgr the price paid then vs now for GHS is the massive foaming at the mouth gorilla that certainly has to be dealt with somehow. Getting rigs with at least as-ordered hash  rate is #1 right now. Only a start, but still a 1st step.

Right in that sense at least better than BFL who has yet to deliver $4,000+ 600Ghs machines. And they have NO plans to compensate. AMT as disorganized as they are have at least made some effort to offer something. Whether that happens is another matter. But its important that they first deliver what was originally ordered. Hashrate at least.

Not true, i was compensated from BFL...after 6 months of delay! and couple emails (1000 of them..lol)

I called DHL nothing with my name in my zip code has been sent.

I'd like an explanation, or a tracking number, please.

I'd encourage all AMT customers to give DHL a call.

[tonyca]

AMT, as you suggested, I sent email to your sales@,  every week I follow up,no reply at all.what is the point?
Can you reply to my email. thank you.

AMT, can you reply to my email? any words? what's settlement ?

thanks.

Alright,

Can we gear the conversation in a direction which may actually help us get the 1u/2u's out the door. Please, if you're willing elaborate on  your experience with server PSU's,  like the HP 403781-001 DL380 G5  vs 2x ESP129 HP 550 Watt .  Like lets discuss server psu's, connectors and the best way you guys would solve an attempt at a universal design for a box for A1/A2/BE200:

The below cases have been developed and ran stable in a test environment using standard atx supplies. Now we need to choose the right server psu's or combo psu's.

2U server case which needs 1600W,  12x 6pin pcie is needed.
2U server case which needs 1300W   5/6 x 8pin pcie is needed

1U server case which needs 750w     5/6 x 8pin pcie is needed
1U server case which needs 1300W   5/6 x 8pin pcie is needed
1u server case which needs 1000W   4x 6pin pcie is needed.

General idea is bulk purchasing of 2 to 3 models or a universal connectors for a specific line of supplies like HP or older IBM's. Any ideas are welcome.

<cracks knuckles> Hokey dokey - my area of fun This of course all applies to any miner that needs only +12vdc

1st question: Only 12vdc is needed with all other required voltages being derived from it on-board the cards right?

2nd: PCIe 8pins? They provide 2 more common returns to reduce ground bounce and technically allow more current to be pulled from the (still only 3) +12v pins. Good to use. Just surprised to see someone is on their toes Great reference to PC power connectors http://www.moddiy.com/pages/Power-Supply-Connectors-%26-Pinouts.html Also good to see lots of PCIe plugs used in all power ranges - by the Molex book max load is EDIT 5-amps per-pin or only 180w 8-amps per pin or 288w per-plug with the always only three +12v pins.

Oh, an on commercial psu's with 6/8-pin PCIe plugs: The 2-pin adapter plug on them (to make the 6-pin an '8' pin one) - not a good idea. Still leaves only 3 real wires being used for the return and that defeats the whole point of the 8-pin plug. Make sure a commercial supply actually has 1-piece 8-pin PCIe plugs with all pins having wires running back to the psu.

With all HP server supplies of that family, refer to http://h18004.www1.hp.com/products/quickspecs/14209_na/14209_na.pdf Pay attention to the input voltage vs wattage rating! Most are dual rated eg found the one you gave on Amazon and it is 800w on 95-120vac in and 1,000w on 200-240vac in. Now, for the highest watt rigs, the HP supplies all support 1+n operation so they can be paralleled, all need to be same supplies so 2 of the 900/1200w ones got you covered up to 1.8kw load off of (2) 110v plugs I will need to find what control pins are used to master/slave them.

As for connecting to them... I use the HP 900/1,200w ones to power all the s1's and soon s3's in my Ant Pharm. I have yet to find a connector for the back so direct soldering is used (and best). Each supply feeds 4 PCIe 6-pin connectors or 2 S1/S3's. Because the supplies are 3ft away from the Ants I use red/black paired uber flexible 12ga wire from McMaster-Carr or AutoZone (McMaster way cheaper!) http://www.mcmaster.com/#9697t4/=szo6yr The PCIe plugs are from FrozenCPU and start as 12" extenders, just cut off the male plug. I'd think that you can OEM them as female plugs with leads. And being OEM - use 16ga wire vs normal 18ga, very very minimal additional cost - much better for power.

For use directly in the case you would of course just solder the PCIe leads directly to the power planes on the psu. In my case I used 14-16ga splices which are perfect for the 12 ga feeds on one side and on the other side 3 twisted together 18ga leads from the PCIe plugs. oh - on 12ga wire into 14-16 ga splices? Only works with flex wire. The fine strands twist tighter together so smaller diameter.

On the small pins control part of the HP connector, pin-1 on the left end is common, pin-4 is DC on/off. Wire to a switch, when circuit closed the DC power is on.

Picture time!

Thanks Rich, exactly what i was looking for, we'll try exactly that today. Any other models work well.There is a heavy supply of second hand refurbished Dell 750W supplies over here as well, for 2U case. Let me get the model number.

[NotFuzzyWarm]

^Bump^^ I've edited post with a correction and additional info https://bitcointalk.org/index.php?topic=569769.msg8075780#msg8075780 ^^

On the HP's they are for Proliant servers and through Amazon depending on 80-Plus color they go for $29-49 new. Like the Dell's there should be a ton of new and re-furb'd ones over there. Just search for  HP Proliant server 1200w psu. Hell, just   HP 1200w psu   should bring them up.

Do you know what the status of order #847 is? I have not checked back in some time. I saw it was said that nearly all orders have been shipped. Is mine among them? And have the 1.2's been upgraded at all?

no working miners despite all of the AMT bluster - despite the great job they are supposedly doing filling all those orders for everyone except the people on this forum. It's getting deep and smelly up in here!

I received 1 out of 2 of my miners. See my posts on page 125 of this thread.

[opieum2]

OK, here's what I have so far. The web interface is in Japanese, err, I mean Chinese (not sure), so I took pictures of the page translated in case anyone needs it. The miner is accessible via SSH and the default user/pass is root/admin. It seems that each board has 200GH/s to 250GH/s. The Pools report a max of 850GH/s but I saw the web interface reported 1TH/s. Each board probably has 8 A1 chips, I can't tell since there is an elongated heatsink on the A1 chips that covers the board instead of the little gold heatsinks that were on the previous boards. Mining results are only after about 2 hours of hashing, 1 hour per pool, Eligius and BitMinter, not at the same time. I also took pictures of the inside but did not separate boards from case since they are firmly attached. The boards can be removed but I didn't do it for this post.

P.S. I ran cgminer on SSH and verified that each board has 8 A1 chips with 32 active cores. Also the ventilation is excellent. After over 2 hours the boards are cool enough to touch and the 2 giant fans keep the system very well ventilated. The fans are extremely loud though. If you have ever been in a co-location with hundreds of servers running their fans at full tilt then you know what I am talking about.

Since you mentioned the miner was very loud with fans, have you considered putting noise dampening foam on there?
http://www.newegg.com/Product/Product.aspx?Item=N82E16811999222

I have been fitting this into my very loud S2s. At least the ones at home. If you are moving into a colo then this won't matter with noise output. But if you plan on home mining this would be very useful. That and installing rubber grommets at various screw points on the cases. All that can help quite a bit in absorbing sound and quieting the systems. With fans that would be another matter. Finding fans that have adjustable speeds (apparently these do not seem to or have a control for it anywhere).

Right now the only ones I have that would be loud are the S2s and my servers in house that are all fitted with noise dampening gear. It does make a significant difference. Hopefully this info proves useful.

Anyone receive an AMT miner today? I think now is when they should be dropping as per AMT's post.

Hey AMT_
Any news on my refund of 27k?
thanks!

no. nothing as usual.

[Chazaki]

It's now been well over half a year and we still have nothing to show for it... If anyone actually thinks AMT is going to give you ANYTHING I advise you think again... They stole $13k from me and plenty more from other customers. If you place an order from AMT then expect to get empty promises, ignored emails and voicemails, complete lack of respect and professionalism - but don't expect any mining hardware.


Since AMt deletes all my posts anyway I wonder how long will it take AMT to delete THIS one?

Hmm, had a knock on my door today. I thought perhaps for a second my bitcoin miner had finally arrived. Sadly it was just my medication that keeps me from turning into a raving lunatic about this whole situation, being delivered by UPS.

I'm sure it will be here tomorrow though, I can feel it in my heart!
