You should be able to get 800+ on those cards each.

settings, please? I can't get over 740 with mine, MSI has been a much better performer for me than sapphire dual-x or gigabyte windforce

800+ is impossible.  My elcheapo MSI 280X only gets 688kH, because it's crappy core only does 980MHz stable.  720kH is the normal top-end speed of these cards, 800kH is a drug-induced hallucination.

all 10 Miner are online right now!
But I am not really happy with the result.
why are you so greedy?
It's not greed. he'd getting 25% lower hashrate than what he paid for and they are also using more power than advertised.  Like buying a bugatti veyron and finding out it has a v12 with no turbos.

You ordered units and not hashrate.
Cognitive mining ordered hashrate.

My rig maybe aren't so awesome (2x 7970) but after a month with it in my room I had enough. So - I moved it to my balkony Grin As you can see it has very good air conditioning there (outside temps are 0°C to 10°C) and the most important - I have so blissful silence in my house Cheesy

Didn't you have any problems so far due to condensation or moisture?
Is your bike plugged in to that power outlet? Huh

looking for a bit of a confirmation on a build before I go out and throw down $2000+ on it:

MSI Z87-G45 GAMING  ($160)
2*600W power supplies (full 600w on 12V) ($40 each BEFORE a $15 MIR)
cheap celeron processor (about $50-70)
2x2gb ram ($40)
6x Sapphire R9 270X dual-x  ($240 each)
6x usb risers ($25 each)

USB w/ BAMT
keyboard
mouse
monitor

Does this look like a good build? Ive read the sapphire cards can be pushed into the 450-480 khash range, so 2.7Mhash/s for about $2250. ($0.80/khash) I plan to use either a milkcrate or a shoerack and a few zipties to hold everything in place.

My biggest concern is of being late to the game. scrypt ASICs are close, and will offer about 1/10th the power draw. I expect these to roll-out on a large scale in the next 2-3 months. The GPU rig would require about 6-9 months to break even - maybe 3-4 months if mining doge, having BTC value rebound, and considering a 50% resale value on the components to gamers.

Buy quality PSU from companies like corsair/seasonic/OCZ. $40/ea implies generic worthless junk. Probably nil stability on 12v lines or will fail quickly.

For the upper CPU price you list, you could almost get the better http://ark.intel.com/products/77775/

Depending on retail prices, might be cheaper to get non-X card variety, which can be bios modded to run at ~1100 mV to give 430-460 kh/s @ as low as 130 watts per card. Although mods like this could probably also be applied to X cards.

Refer my PM for cheaper risers.

Scrypt ASICs will be inherently limited by RAM - which was the original reason why scrypt was chosen? - which translates to very high purchasing prices for customers. I would say that we're going to see similar final ROI times between GPU and Scrypt ASIC. One is cheap but burns a lot of power, one uses nil power but capital is very high. Also in regards to your estimates, keep in mind that only a month or two ago ROI time for a rig like this would be 40-60 days. If markets rebound quickly and you are willing to wait without cashing out...  Cheesy

saw your PM - i actually ordered some ebay risers last week but at this point might still buy locally for $10 more just to get things going sooner than later.
on review of some other builds - it looks like going with a 4-slot mobo would be almost $100 less than a 6-slot variant, and that BAMT can run on only 1-2gb of ram (another $20 saved)

after some price checks, it looks like the local Tigerdirect actually has very good deals and is competitively priced against NCIX.ca and newegg.ca - They had about 12 of the Sapphire r9 270x in stock today (only 2-3 of the MSI 280x) at a recent price drop from 270->240. a few different guys in the store knew i was looking for mining gear before i even told them, and pointed out a few good mobo brands (in 6-slot flavors).

RONA has some amazing storage crates that are about 20% bigger than milk crates and I currently use some for holding 2 antminers + psu each. using one for a GPU rig would likely be pretty simple and extremely easy to stack.

few remaining questions:

1) AM3 vs 1150 vs 1155? It looks like these all offer similar benefits, but AM3 seems to be about 10-20% cheaper for both the mobo and the CPUs
2) any issues i might run into using zipties to support the cards and mobo? obviously i dont plan to let them be loose and swinging around, but without a GPU in fornt of me its difficult to visualize the tie-points i could/would use.
3) if using USB risers, should the mobo be vertical? most builds have the mobo flat but this seems like an invitation for dust buildup or for foreign object to land on the board and short something. with a crate, vertical orientation seems simple and better
4) anything else i should consider? Is it as simple as assembling the rig then booting it with a BAMT-loaded usb drive and then tweaking settings from there? do i need to run a monitor from the mobo or one of the GPUs and do i need dummy plugs?

They are USB Block Eruptors 333.6Mh/s Rev3.0, I eventually want to get 5 Ant miners, there was a Ant miner sell on ebay but when the intventory begin to run out the seller upped the price from $60 USD to $80USD and I couldn't get it when I was finally to have some of the cash. The only one I got lucky with was a Lot of 3 USB Block Erupters for around $50 USD.

The Power Supply that I am using can handle 5 USB Devices alone. it is from a old Linksys Wireless B 5V 2.5A

Seems expensive to me..
I'm running 4 x 280x's which gets me about 2.7 and I paid less then 1700 for everything along with a 5 slot mobo, 2x700w psu.
I did have an extra hard drive, and ram though.
I also didn't waste money on usb risers either..

USB risers are anything but a waste of money.  Unless you like annoyingly short ribbon cables for some reason...  They are a $20 (well, less considering you still need $10+ ribbon cables) addition that makes the difference between a ghetto rig and a pro setup.

+1     I am planning in USB risers because
a) they will last longer because there is no flimsy ribbon cable for it.
b) they look better - The rig wont be a centerpeice, but it will hopefully be visually appealing.

Dont belive every troll who doesnt know shit.

Your cards generally are not able to do clocks which are  needed for 800+khs. You need minimum 1160/1800 for that.
Besides, pushing 280x to its limits not even closely efficent anymore. Those cards will consume way over 280W each and will be insanely hot when you push them like that. As a result fans would not survive over 3 months. Its a common flaw of several cards, If fans are running high rpms.

800+ is impossible.  My elcheapo MSI 280X only gets 688kH, because it's crappy core only does 980MHz stable.  720kH is the normal top-end speed of these cards, 800kH is a drug-induced hallucination.

It is possible and I've been doing it with multiple rigs for a long time now. You should really do some research... I do overclock the cards but there is nothing wrong with that. Also please note, I undervolt them before I overclock them even Wink They run cool... just fine.

https://litecointalk.org/index.php?topic=14339.msg111704#msg111704

All my settings, screenshots, etc. are there. I have a 6 card rig and a 4 card rig running similarly.

Getting the proper BIOS flash, then undervolting it are great ways to get good kh/s and run on less power. You should be able to use the same BIOS on your cards that I'm using on mine...

This image below is old and was taken after the rig was running for 24 hours...



This image below shows sgminer which has been running for 12 days or so... so don't tell me about stability. Its also in a room with a pretty hot ambient temperature and you can see the cards are staying plenty cool..



and.... one more pic.

elchorizo, For heaven sake, read the thread before you make your post.
You are running DC2T and Toxic´s! Those cards can do 1140/1800. Majority of 280x cards can not.

Besides. Those cards fans are screaming loud at 70+ %.
Of course, its possible to do 800s with proper setup. If its worth to spend so much more money and power cost on Toxic cards for gaining additional 50-60khs is another story completely.
