My mining rig (2x) XFX HD 5830 Video

Most important thing, leave room for your PSU to breathe, dont just stack up Watts here and there.

True, but don't leave TONS of room or else it will be running below optimum efficiency, wasting money.

Good point!

Yep, that's pretty much it.

There's a great deal.
2 x16 riser cables for $9
Can't beat that.

looks great, but i doubt the quality, do they work good?

Is your balcony covered?

[condorhero]

innervisi0nn,

What and how are you overclocking your 5830's? I can only get up to 260M/hashes...

[miningnew]

Do you connect the devices or is there a option that they both calculate solo?

[innervisi0nn]

@freakin no its not covered

@miningnew huh?

@condorhero I am now getting 300 meghash/s using phatk with phoenix miner. I am overclocked at 975 core clock / 340 memory clock.

I was using guiminer before with MSI Afterburner for the overclock, but phoenix miner via terminal is doing so much better + less stales for me!
Ill write a tutorial if need be

Sorry for my bad english:P

I'm planing to build a mining rig how can i put 2 in one System just plug them in normal?

[horgh]

I've two Sapphire 5830s. I get >300 Mh/s from other one and only 270 Mh/s from other. Other runs fine with clocks 1003/300, voltage 1250. Other is worse, it doesn't help to add voltage to that card. It just won't run any faster. So what I'm trying to say is that these cards differ from each other, so if someone gets high Mh/s and you don't it can be that there is little you can do about it. It's all about how good card you happen to get.

2nd rig on its way. What do you guys think?

Watched the vid... looks nice.  I have a similar setup with 2 Sapphire 5830's...

was wondering 2 things:

1. what is the gpu temp graph on the left that you are using... looks nice

2. Even with the config file mod I cant get afterburner to OC my clocks beyond the standard 875.... I have to use sapphire trixx, but that will only do the first card because they arent connected w crossfire cables.  im using the newest beta version of afterburner.  what version are you using? anything else im missing??  tia.

1) just google GPU Gadget windows 7 there are plenty to choose from

2) Try plugging the monitor cable dvi/vga into the 2nd card. You have to do 1 card at a time. it activates when you plug a cable in.

1. OK thanks!
2. Problem is I have a headless rig with dummy plugs no monitor

1) nice
2) Plug at-least 1 monitor in there, use the rest as dummy plugs. You can swap them depending on which GPU you want to tweak.

Try this:
----------

You have 2 video cards, plug 1 monitor, the other dummy plug, tweak with sapphire trix tool or msi afterburner.
Plug monitor into 2nd card now, dummy card into 1st, tweak again, when satisfied, close it and run your miner.

Then you can plug 2 dummy plugs to keep it going.

looks good from the vid.

Thanks!  I got some advice on another thread and im now using only ATI TOOLS, got rid of trixx and afterburner.  ATI tools lets me do voltage and gpu/mem clocks on boht cards with dummy plugs using teamviewer   and it has nice graphical monitoring built in.  love htis little proggy.
