Lol I will be examining those options haha. For anyone interested eBay has some of these motherboards for 107 free shipping. Great Price. I'm going to use Amazon as I have some gift cards.

I got the risers from eBay. I'm working on getting more myself. The shelving is nice, it's 14 at home depot and comes with 4 or 5 shelves. I liked how open air and inexpensive it was for this kind of purpose.

Of course I woke up this morning to my Asus system dead again. It's been finicky and I think I now know the problem. It was a motherboard which had been acting odd in the past. It wasn't responding to the reset switch this morning, so I pulled power and waited a minute, then flipped the switch back on. A bright flash and some smoke occurred on one corner of the motherboard. I'm guessing something finally died on the motherboard.

When I get home later I'll investigate and check each gpu and the cpu and memory and psu, though I'm sure it's just the motherboard.  Time to order another 2. One to replace this and one spare.

It's always something, am I right?

SCAM

Don't mine this coin! The dev is knowingly being a jerk. The coin is worthless, and the difficulty will take 3 years to change. No transactions, no exchange, etc.

For what it's worth guys, after reviewing some competitor hardware, I retract previous statements I've made in saying that it seems hard to believe.

I can believe 5mh in a 1U system as I've seen some equipment doing it.

I think it's possible they can stuff 25mh worth in a 1u, but that the thermal load won't be forgiving.

Now that I've seen the hardware is achievable, I hope this company can build my confidence up in them. I'm also awaiting a PM from Fiaz, hope he responds ...

I haven't thought of 1" either, it's 1/2" $14 shelving from home depot, and pvc pipe/zipties. That's how all my systems rock and roll lol.

Lightweight but provides good support, it's cheap, easy to work with, and recyclable for other purposes.

I updated my ASUS 270X review with some more tidbits: https://bitcointalk.org/index.php?topic=324938.msg4630466#msg4630466

Quirky cards. They will definitely mine, and for the price I got them (144/ea) they're not bad. I wouldn't pay more than 180. I think with a Prolimatech setup they'd do better, the memory chips aren't cooled in any fashion which isn't helping. Until I can get more Prolimatechs (I need 7-12 more lol..), I will have to find a way to keep these stable. I have 5 in a rig right now, 3 of them at 437, 1 at 270 and 1 at 400.

The weakest one is due to the high temp it's running right now, 80*C. The other weak one is in the upper 70's. The rest are in the 60's.

So today has been a madhouse. Been busy all day around the house and home office. Put 2 systems together properly instead of letting them dangle sideways with velcro and cardboard, I moved some systems around, did a bunch of stuff. Never finished half of my list, nor got around to working more with the ASUS 270's. I am tinkering right now before bed, and will tinker some more tomorrow.

Here's some shots of the MSI 270 rig I just put together, as promised. This one is all USB riser, featuring a Seasonic 1050 PSU. One of the nicest things about this PSU is its' copious selection of power connectors. Also it exhausts the heat out the rear vent near the AC connector, instead of up like some.

However, unlike other Seasonics, and unlike any other PSU that I own, this thing sounds like a jet! I dunno if I have a bum unit or if they're supposed to sound this way.. but it's the loudest piece of computer equipment. Even being 1 floor away I can hear it.

This is currently working at 2.46mh on tagmining.

And I know you guys always look forward to seeing my patented PVC pipe/plastic shelf and ziptie setup.







Another nice thing about the USB risers is all the 'free space' around the cards, promotes healthy airflow.



As you see these are running the stock coolers. They're nearly silent, I'll probably keep the stock coolers on these cards until it starts getting into the spring/summertime. It's currently 27*C in the room they're sitting and the cards are running in the mid to upper 60's, except one which is 58*C (the outermost card).

Congrats! Glad to see you're lucky with that 2-4 estimate.. 45 days later and my toxic still hadn't shipped, so i cancelled the order. Then I remembered, days later, why I was holding off on cancelling it: I need another GPU lol..

No power goes through the USB cable. The ASRock 970ex4, if you can find it, will do 5 GPU's. I'll post pics of mine sometime today.

Sounds good, be glad to help!

I'm going to pass out now. I don't even recall if I got sleep lastnight LOL.

A certain 24Kilo's rig is up and running, really nice hash for stock clocks too!



Now to see what we can do with it.

[02:05 US Eastern time]: Live from Sydney.. or.. through Sydney! Tuning progress (the text below, not the image above)

975 / 1400 = 422kh @ ~74*C
1050 / 1500 = 455kh @ ~75*C
1080 / 1500 = 467kh @ ~75*C
1120 / 1500 = 482kh @ ~76*C
1145 / 1500 = 492kh @ ~77*C

(temps are avg of all 3)

Tuning Complete:

They can indeed. NASA learned the hard way one time, lost an entire project due to a comma.

Can you PM or email me your /etc/bamt/cgminer.conf file, as well as your /etc/bamt/bamt.conf file? You can remove worker username/passwords if you want.

I have Asus 270X TOP's which flashed just fine. From what I've read on some forums, the .exe file which force-flashes the cards should force-flash all 270 Asus models.

Don't feel like an idiot mate, I can't have my friends say that about themselves. These cards are tricky sometimes. I have rigs which work great, and I also have mystery rigs with ghosts in them. It's a matter of finding the right settings. I'm perplexed also, and am convinced it's something simple.

Summary / Highlights

This is definitely a neat card. If you can get this for $220 or less, I say grab it. Up until now the ASUS 270 has had my nod due to how quiet it was--much quieter than other 270 cards, but not silent. MSI's TwinFrozr 4 cooler is astounding, it's what I would say all high-end GPUs should have. It's nearly silent, quieter than the ASUS, in fact nearly on par with the Prolimatech's sound output. For cooling, it does really well, keeping the card in the mid 70's while being overclocked in a warm room. The cooler also covers half of the memory chips, and halfway covers the remaining half.

What's most surprising isn't just the hashrate (1kh higher than any other 270), but it's the power usage! All other 270 & 270X's I've checked so far have used 175-180 when pushed to their limit. This card is drawing 167w max! This shows high efficiency, but also that there's likely room to pass into the 500's. With an 8w savings, times 5 cards, you're saving 40 watts.

Silent, super-efficient, and great looking: This is a must have.

I'll post pics of the rig when I get a chance.

I have 50 USB ports being used by BE's right now, but if you think about it, that price isn't bad for what you're getting. You spend like 1.5-2k to get that much hash power now, but look at the power savings!! More than tenfold.

It's also in line with what other scrypt-asic companies are offering. For my usage/desires, I'd need many, many of these things. Many.. I'd want to basically use the same amount of power now (4800-7200watts) but increase my hash, which is what these would do.

With 4800 watts available, figuring 1.6w per device, that's 3,000 units. Can't do that without factoring computer power.. so let's see... 100w per computer, 10 computers, that's 1kw, which leaves 3.8kw, enough for 2,375 devices (10 computers). 2,375 of these devices running on 10 computers pulling 4800 watts is 166,250kh.



Of course I can't afford that many ($190k, not counting shipping/import fees).

But the power savings is awesome on these things..

Because they need to crack banking encryption..? Microsoft, Apple and some embedded systems are in bed with these guys. They have the source. They have root.

They don't need much else.

Bitcoin available for more than that!

Another guy in the thread confirmed dual mining at the spec'd rate. Wish I could get some of these lol.

That's a pretty slick device, I'd love to replace my 50 BE's with 50 of these lol.

Nuh-uh!!!!!!!!!!
