OH MAN... my 10 gigabyte 270s have changed to status "Shipping Now".  So it looks like Amazon's 2-4 week shipping estimate on these was about 10 days.

So stoked.  By midweek next week, I should be part of the 10MH+ club.

I'm coming for you Kilo and Vesper!

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..

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).

That's a slick little set up you got going there.  I never thought of 1" PVC.  Cheap and easy to assemble.  Great idea!

I haven't thought of 1" either, it's 1/2" Wink $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.

Vesper,

Great set-up... going to use your idea... where did you get the USB risers... they look like a great solution.

Ok, I'm getting my rig tomorrow sans (without) risers, so I'll test with what can fit. GPUs are Sapphire 270, mobo is Gigabyte, and Seasonic 1050.

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?

PSHHH... that's just how you know you broke it in.  Now it's time to push it harder!  Just jumper that component with a paperclip, and you're good to go!

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.

Finally home and ready to set up my first dedicated mining rig! I also built a few PVC cases for my set-up, they work great and are easy to build.

Got those Gigabyte 7950's from you fuse  Cheesy I'll let you know how they hash later.

Got another Sapphire 7950 that I am hoping is not a dud.

And 2 brand spankin' new Gigabyte 280x's.

I'll post some stats later tonight

Wish me luck~

If there was one 270 card I could get to replace my other 270's with, it would probably be the MSI 270.

Anyone wanna trade cards? Haha. I love the stability, and how easy it is to get high hash out of them. I'm going to see if I can source more and sell off my other 270's.

@vesperwillow, Nice PVC frame.  Do you arrange them on shelves?  I went with aluminum to make them self contained and stackable.  After a few iterations, I have it down to about $50 in material for a 5/6 card rig.  The time involved is still high though, but getting better.

@Dabs, thanks for the review of the dual miner.  Interesting little device.  I am assuming the manufacturer has them priced at the absolute max the market will bear.  If they were about 25% cheaper, I'd consider some, but since my winter/summer electric rates are around $0.14/$0.17, the benefit just isn't there yet.  Certainly watching.

@Fuse, congrats on the cards Smiley  Glad they shipped faster than expected.  Good luck with assembly.

A side note from my efforts today in case anyone needs to balance dual power supplies, a 7950 pulls about 60W from the powered riser and about 150W from the PCIe plugs when running around 630kh/s.  I am wondering if the ratio is similar for other cards?

Chicken, yeah I stack them into tall racks of hash and warmth. Hehe. Aluminum sounds diesel! Mine isn't diesel, but I'd say it's about $10-$15 in material per rig, the majority of it being the PVC fittings.

Sapphire 7950 Vapor-x was really bogging me down, at stock clocks it was at best around 350 kh/s, but I finally got it up to around 650 kh/s

-I 20 -w 256 --thread-concurrency 40960 --gpu-engine 1100 --gpu-memclock 1500 --target-temp 65

You guys see anywhere you think I could grab a few more hashes? Any attemp at using -g resulted in a crash.

Gonna let this run for the night and then on to the next cards!

using sgminer btw  Cheesy

The -g switch would probably work with a lower TC.  I couldn't guarantee you would see a difference though.  Vesper is the magician with this stuff.  I'm not sure how, but he always seems to pull some extra hashes out of his hat.  But 650kh is pretty respectable.  If the temps are good, I would leave it, but that's just me.

Cheapest I can get them is 0.11 BTC shipped from China to me, if I order 300 units. So let's pretend that Fuse orders 100, Vesper 100, me 50, and you 50, we meet the minimum 300 units to get that price. I prefer to deal with as few buyers as possible, because it's a royal headache to package 300 individual units to 300 different people.

Dabs, can I borrow... um... 11BTC.  I promise to pay you back one day.  I wish I was that kind of baller, mate.  God, I wish I was that kind of baller.

I wish I had 11 BTC too. hehe. I spent all of my one bitcoin to buy a few billion moon coins, and I think that might have been a mistake. Well, here's hoping it goes to the moon this week.

If you make a million dollars, can I borrow the BTC then?  Grin
