Lol those pictures are hilarious. The processors are sitting on top of resistors.

Check out this real FPGA photo - link below.   See the metal leads for the I/O channels aligned around all sides of the spartan 6?. ASICs are the same. Now look at the pic in the first post again where they have 10 of them on the board.

WTF is that even supposed to mean? There are MANY MANY different package types that don't involve the pins being located around the perimeter. There's no such thing as an "ASIC package". They can be put in any suitable package, and the exterior packaging has absolutely NOTHING with the function of the chip itself.

Both QFN package type AND BGA type, which are what's being used by the major SHA256 ASIC designers right now, are mounted without any leads visible around the perimeter. Your post is completely full of fail.

There's PLENTY of evidence of a scam here. Package type is not among it.

It's fair to assume though that at every position on the board that an ASIC chip is placed that the immediate area surrounding the ASICS themselves should in fact be constant for each chip, correct?

Because on top of the fact the chips are blatantly photoshopped upon the board without the layers blended, the underlying PCB area has no routine regularity chip to chip.

So his statement stands in that the processors are in fact just cloned and pasted upon a random generic board containing diodes/resistors.




Yes, I agree that the board is inconsistent. Is it fair to assume that every single chip be laid out the same? Not necessarily. Not if the chips are daisy chained. Would I expect to see generally the same components dedicated to each chip, in GENERALLY the same area. Yes. So the lack of continuity is, in fact evidence of a fake.

What I reject is the idea that the lack of externally visible pin connectors on the PCB is evidence of ANYTHING.

His post is nothing more than static that just dilutes the other legitimate points about the board. I have said all along that I believe that this thing is a fake, but when people use false and inconsistent statements to support their point of view that it's fake, it waters down the message of WHY people should believe that it's a fake.

Anybody who knows ANYTHING (and I don't proclaim to know much) about ICs knows that mounting system and packaging has NOTHING to do with function. And that many chips are actually often offered in different containers/mounting configurations, while maintaining exactly the same function. Same chip, different package.

I'm not jumping on him for calling it a scam. I'm jumping on him for speaking about things of which he possesses zero working knowledge.

It's funny though the more you look at that board and laugh, the more you wonder how anyone but the stupid and greedy would jump in and purchase.

Then rewatch the piss poor effort of the video and it's just ridiculous!

Now they're asking for more money and more time to make their scam more convincing!!!

Truly scandalous...Grin

I totally agree.

What really gives it away for me is the that 10th chip in the odd place. If you look at the resistors on each row, you can see that the resistors off to the right and left are consistent, meaning there were 3 identical circuits. Yet the middle row has a chip sitting over the resistors that are plainly visible in the identical rows above and below it.

How can this be? How did 3 identical circuits handle the removal of reistors in place of a chip? Are we to believe that those other resistors are just there to emulate a chip? Why not put actual chips there, and get 20% more hashing power, without the wasted heat and energy on those resistors?

If they had added two more chips to the photo, it would have been FAAAR less obvious to the casual observer...

not knowing what goes around/under ICs, Ican tell you that the angle/perpective on these chips is different than that of the rest of the board.

Also, how do you cool them? No holes for mounting a heatsink that I can see (heatsink on some secondary chips though...).

I would have thought some AV system because of the heatsinks, but the antenna and rj45 plugs make me think of a wifi router of some sort (missing the wifi card, probably), but the board looks biiiig...

True story. The shadows/glare on the "ASIC" chips don't exist on any of the surrounding chips.

Indeed yet the shadow from the overhead light affects the whole board and all it's other chips...but not the ASICs.

So many holes in this ruse, yet to some there's always an excuse...

Did a little fiddling with the images they released.
after perspective correction ( aligning the image because is was shoot in an angle ) you can clearly see how misaligned the chips are, specially the 1st chip in the 2nd row is totally whack !
no way that chip alignment tolerances would be that much off .
that was a hack job whoever Photoshopped them onto this PC main-board.

Hot Damn, RayJay has completed the development for the CedarTec ASIC board!

Are you taking pre-orders, RayJay? I can only pay in non-reversible payment methods, at the moment. Bitcoin is preferred, since I really enjoy throwing money at Bitinstant these days.

Hope that's okay. Although I could do Moneypak, or international wire transfer, if need be.  Cheesy Cheesy Cheesy

You reminded me of why I don't like forums.
I/O leads not visible on Avalon and BFL? Look again. BGA would not be used in this application. And daisy chaining ASIC? Lol, because you want to reduce the throughput? This is the end of me responding to trolls. Trolls are why I started hacking over a decade ago.

+20% hashrate, ok sold, you've justified the extra $250!!

Don't suppose you could shop in water cooling as well? Wink

MAN i can see from the moon that ATX power conector is placed over a few resistors.... is a clear PS... and there are a few other things that are on top of something else in the board, probably to cover letters on the original board.

You can only change the subject for YOUR post. Not the original one.

Before you shut this thread, let's have a little photoshop competition for the best Cedartec board revision...

Rayjay has laid down the gauntlet, show us your shittest photoshopping skillz;

Watercooling parts unceremoniously dumped on the board scaled at entirely the wrong size,

Components that bare no significance what so ever,

Fans, tonnes of them..

The cruder and unrefined the photoshopping the better!

Additional points for squeezing in a random hand holding a phone.

Extra additional points if it's a hairy hand holding a phone!!

A piece of artwork Cedartec woud be proud of!

Make my day! Say thanks if you found me helpful Smiley BTC Address --->

One thing that it gets me apart from something placed on top of something else, is the 0 respect for the crytografy of the board. anyway got it... its a pc board.

wahey! I think that second heatsink is also dumped over something. For a fact the ITE I/O controller had a logo in the other picture that had been removed in this pic, beginning 'i,n';
