I build a custom 2100 - 2300 kh/s mining rig with 5 gpus mounted inside of a Half XB case

Specs -
Motherboard- Gigabyte UD-5
Processor Sempron 145 (upgradeable)
Gpu - 5x6870 each produce 420 kh/s stock. (I know what git hub says they use a cypress processor instead of barts but are factory made and come with a full warranty)
PSU - Kingwin 1050w (upgradeable)
HDD - 80 GB sata 1 (upgradeable)
CD/DVD - Liteon standard DVD burner
Case - Coolermaster Half XB

I have 9 of these running in my house and they are fantastic. They are very portable as they are less than 2x2ft and weigh about 30lbs. The power draw is better than any other card on the market 170 watt to 420 kh/s stock. I custom build the case with a 800cfm fan on the top cutting a whole for in to mount around to get maximum airflow. 4x Bgear 103cfm fans and 2 80mm 40cfm fans are used for exhaust. GPUs are evenly spaced along the top of the case with custom rigging and plenty of space is left open for the cpu to get air. The total wattage  used is around 960 and standard settings. Clocks on some cards can reach 460 but not guaranteed for all. And if you wish to overclock I would recommend upgrading the power supply.
Just for everyone out there yes I mean 5 cards in a Half XB, Yes I mean each 6870 produces 420kh/s stock. I believe the card was a specially redone 1600 core 6870 which is why it allows it to get so high but I am not sure. Anyways
Computer is the most power efficient and price effiecient you'll find

Thank you for your interest, Photos. Videos even demos can be shown to those who are intested

pics or ad is useless

How on earth are you getting 420khps out of 6870's without overclocking???

2100 kh/s aint no mining beast btw ... lol

Agreed.


Exactly. How are you even getting over 380kh/s period? I have yet to see anyone get their 6870's that high even with OC.

You seem to be a pretty honest guy, but I guess at this point I am just wondering why you aren't posting screenshots or pictures of the setup.  If you are indeed being honest about this, I am sure that you could easily post a picture.  This would not only give you credibility, but it would also positively affect how quickly you could sell this thing too.

Yeah dude, your machine isn't niche. People throw 6x 7950s into whatever kind of spare frame/milk crate/cardboard box/shoe box that they have laying around and dominate 2.1KH on a daily basis.

Post pictures of what you have for sale. Failing to do so makes your intentions evident.

Hmmm.....


That explains the kh/s rates. Someone just slapped a 6870 sticker on it, even though it is just a 5870. (Rebranded)
Can anyone actually find any info on these "cards". I can't find any info about them on the sapphire site (all of their 6870s use the Barts like they should).
The only thing that pops up for me is something on techpowerup that says these were supposedly released this year. (Sapphire HD 6870 1600SP Edition)

Well now I feel better. Actually was starting to think someone knew of some magic way to make a 6870 get that many kh/s.
Just smoke and mirrors. haha.  ;)

If I can get my hands on one of these GPU's, I'm going to.

Edit:  Looks like this things have 1600 shader units!?!??!  Anybody know where to get one?

How many USB ports can you put on it? I am in the market for a Litecoin miner that can also host BFLs.

Looks like I will be replacing my 6870's very soon.  ;D
