I'm new to mining and I'm wondering what the best settings for a 5830 are.

I'm currently testing one 5830 @ clocks 975/300 with phoenix miner with phatk kernel with 3% mod

with the following arguments VECTORS BFI_INT AGGRESSION=7

Running windows 7 x64, 11.6 drivers, 2.1 sdk, i can only get an average of 270/280 Mhash/sec.

What are the best settings and options that will maximize my performance ?

I have a Gigabyte GA-990FXA-UD5 Motherboard and when fully populated it has 3 PCI Express 8x slots, 2 x4 slots and 1 x1 slot.

I was wondering if i would be able to fully populate this board with 6 cards with extenders ?

I have a Strider 1500w powering it, I'm just not sure if the motherboard will handle it.

I'm looking to build a new triple 6990 rig and I'm wondering if anyone can help me with a choice of power supplies.

I know that a lot of you in the community use the AX1200 which here in Australia is more expensive then the Strider 1500W.

So I'm not sure which one to choose; the AX has a single +12v rail where as the Strider has 8 +12V rails but has a higher wattage.

I'm looking into getting a new mining rig with 2x 6990s, i will be running them in windows 7,
so what i would like to know is, does running them in crossfire cause any performance loss compared to
just using a dummy plug ? and also will this dummy plug setup work http://blog.zorinaq.com/?e=11 ?

Thanks

Hi all,

Just wondering if anybody had an idea if the ASUS P6T7 WS SuperComputer motherboard could run 7x Graphics Cards,
by extender cables of course.

Would most likely have multiple power supplies running too, but just imagine 7x 6990s in one rig...

I'm very new to mining and its about the time of year i upgrade my PC and i was looking into
building a dedicated mining PC.

Here are the proposed specs:

AMD Phenom II X6 1100T
Gigabyte GA-990FXA-UD7
8GB Corsair DDR3
Powercolor Radeon HD6990 4GB x2 maybe a third later on this year
Silverstone Strider 1200W Gold
Most probably running windows 7

inc HDD and Case it comes to around $2500 Australia Dollars

I would like to know how profitable mining would be with a rig like this?, would it be better to mine
in a pool or solo mine ?
What would income figures look like ?

Thanks,
