Watch how popular mining becomes when the USD crashes later this year and bitcoin goes back up to $160

I get about 215 mh/s out of mine. Power usage is really low iirc. hash/w is 1.8..

Its a great filler in my main rig.

Re: Motherboard of choice for 6 or more GPU's

I have 6 cards per rig, 3 of them on powered risers... two rigs... 3 Seasonic 1250 Watt gold power supplies.  Each power supply powers 4 cards.

I have the Gigabyte 990FXA-UD5 and the MSI 990FXA-GD80 and they both can handle 6 GPU's I believe (still waiting on 1x risers to arrive).  It looked like they had been out for awhile so I didnt know if there was anything better on the market that most people were using or not.

Hey I have the GA-990FXA-UD5 and do you have to short one of the slots to get the 6th working?

Just switched to CGminer-6990 gained an extra 30 mh/s per core!

Just switched to CGminer from Guiminer/poclbm and for those who have the issue where Guiminer decides to power off your card and start producing really low hashrates well by switching to CGminer this is not a problem.

If anyone is interested this is my machine:

Antec 900w HighGamer PSU thingy
AMD Phenom II 1100T BE
Gigabyte 990FXA-UD5
Corsair C9 1600 Vengence Ram - 8GB
Powercolor 6990
Asus DirectCUII 7850
Gigabyte 7770OC - This card is so power efficient im thinking of doing a 6card low power rig with these.

Maxes out around 1.2GH/S under CGminer and is so much more consistent in hash rate.

The 6990 under Guiminer would occasionally get 370mh/s per core but under CGminer its fairly consistent now.

Also I believe you watercool with Distilled Water. Leaks are bad yes but Distilled water inst a conductor until it becomes dirty?

I dont know if Asus have released an updated bios but that really helped my 6950 maintain temps and reduce flickering..

Might be worth a look

Hey guys,

I made a batch file that makes removing these files a breeze. you might want to check it out and edit it as you see fit.

Also If you get OpenCL errors or crashes on startup and have to re-install openCL. use the CleanOpenCL

Cheers

Heh 6990 on stock clocks runs upto 99 with other cards next to it Sad

Underclocked & undervolted it and gained a few mh/s once the temps dropped to 70-80 degrees. cool hey Smiley

Current rig is mining(single 6990) 720 mh/s but..waiting delivery of:

 XFX Radeon HD5850 Black Edition
 Radeon HD5850 1GB Powercolor graphics card
 ASUS EAH 5850 TOP 1GB Graphics Card 110% speed
Sapphire Radeon AMD HD 6850 1GB Graphics Card
AmazeTech ATI Radeon HD6850
VTX Radeon HD 6950 2GB GDDR5
 ASUS HD 6950 2GB GDDR5 DIRECT CU II AMD ATI RADEON
ASUS Radeon HD7850 HD 7850 DC II 2GB 2 GB GDDR5

GIGABYTE GV-R777OC-1GD Radeon HD 7770 GHz Edition"

Once machines are built should be pretty close to 3Gh/s without further overclocking

Re: Quantum Computing and bitcoin

Quantum Computer's bits can be both on and off at the same time and therefore allowing exponentially larger simultaneous calculations to a single problem.

I.E a Quantum computer could smash through a 256bit key in microseconds because it could test more hash's simultaneously than what a standard pipeline executing computer could.

IIRC D-wave are close to true quantum computing but its not quite there yet...

Re: World War III and BTC

Why does everyone assume WWIII would be like WWII?

Wars are very unpopular these days and I think the only wars we are going to see between the G8's would be economic or coldwars.

None of these self interested leaders would risk political suicide by going to war with any of the other majors. Will always see the next tier of countries duking it out with influence from the majors.

Its scary how much of a difference this makes. I did this on my 6990 and it shot up to around 720mH/s
