Topic: [ANN][TAG] TAGMining.Com is now the official pool of Tagcoin! - page 11. (Read 45655 times)

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  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~

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.

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!

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?

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.

Vesper,

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

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://bitcointalksearch.org/topic/m.4630466

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.

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

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..

Babomancer, PM sent.



FYI...

It appears we're forking like crazy again.  I was told we were behind the curve this time, but it now appears that we are ahead of the other pools with a difficulty in the 20s.  Get some, ladies and gents!

-Fuse

Let me know how those hash!

Looking to get a few to fill out some empty spaces 

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!

You could probably run the riser power off another PSU easily.  Even something like a sub 500W PSU... at least in my mind I could see that happening.  But you have to think that powering the risers is the same as having them on the board.  The power draw is going to happen one way or another.  It's 6 of one, half dozen of the other.

The most PCIE slots you'll get on a traditional motherboard is 6.  This is a processor limitation.  I can't remember the thread, but I had posted it somewhere.  There was a really great discussion on some computer engineering forum, or something like that, about whether it was possible to have more than 6 on a board.  Now, if you went up to a server MB with dual CPU sockets, like the TIAN boards, you could go up to 12.  But the cost to do that is way more than going with 2 GIGABYTE GA-990FXA-UD3(6 x PCIE) or ASUS M5A99FX PRO(5 x PCIE) MBs, both around $140 shipped Prime on Amazon.  I know you have different sources for goods, but the price should be close to that there as well.

The H81 board is slick in that it is really a bare bones mining board.  One particular feature I would want to test is the additional power input on the motherboard for the GPUs.  I'd love someone *cough cough Vesper* to grab one to test 6 cards sans powered risers.  I've seen them in the last few days on newegg and ebay for like $60.  You can buy them off members in the forums for like $170.  Culex has them for $100 if you could work out cheaper shipping.  But better resale value would go to the gigabyte or asus boards.

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.

Heya, with the USB 3 style powered risers, the power for the card comes from the power supply directly, it does not ever pass through the motherboard? If so, then the comment about needing only enough power to run the motherboard is true? Then you can power the the motherboard (and cpu and ram, the system) with one power supply, and you can use a different power supply to power the risers and GPUs?

Also, that means any motherboard that has the number of pcie slots you need would, in theory, work. What's the consensus on the cheapest MB that has the most slots? Or what are the top 3 motherboards for 4 GPUs, 5 GPUs, 6 GPUs, and 7 GPUs? Are there MBs with 8 slots? 9 slots? Is that ASRock BTC motherboard any good since you are going to get powered risers anyway? (or maybe it's redundant, or maybe it keeps the system really stable.)

I could ask this in another thread, but I figure you guys would be better, hehe.

What PSU are you using? I find that if I overclock mine to that level I can get the hashrate described, but it's not stable. After about an hour or so BAMT cranks the CPU to 100% and everything freezes and I have to reboot. I'm only using a 750W PSU so I thought maybe the overclocking was drawing more power than I thought (I have 3 R9 270s), but if you're only drawing 620W from the wall, then maybe that's not the problem and maybe it's just an issue with BAMT.

Thoughts?

Sounds good, be glad to help!

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

Ok, vesper, I'll let you know when I get all the parts for my rig in. The only thing I'm missing are risers, so I'll get some from Taiwan. I made a downpayment at the store to reserve the last remaining 270 GPUs.
