I have one rig with 2 5830s and just ordered my second with 4 of them... 
The two I have were unstable anytime I tried to clock above 970, or memory below its normal 1000... what gives... how are you guys able to OC them so high and they last for days. (shrug)

Make sure when your dropping the memory, between 400-600 the card is extremely unstable. The Sapphire 5830, has a power save mode, which underclocks the card to 157/400 I think. ** I know the Core Clock speed is for sure, not the memory clock speeds in powersave mode **
Drop the memory clock all the way down to 300, make sure that the card is running above the powersave 0.9V
MSI Afterburner - Can't do it ** not that I know of anyway **
If your using ATI Tray Tools, set the Voltage profile from 0.9 to 1.163 then save the core clock somewhere between 800-1000 or where every you want, and the memory down to 300
If you bump the core above 828 I found that the card hardlocks using the 0.9V card profile.
Start by adjusting it at 5MHz increments and test for a couple minutes mining, making sure you keep your temps below 80C. You can run the Temps higher, but its not recommended for long term use, especially 24/7 100% utilization lol
When the card starts to studder back it off by 20MHz, then start playing with the AGGRESSION and WORKSIZE and other RPC Miner options.
It takes some playing around with to find the sweet spot for the card in your system, but when you find that hotspot, she's good to go for a long time
, unless some fails of course 
YES, Double YES! thank you. I can finally clock both cards the way I want and without crashing them. the key was removing all the crappy tools like afterburner, trixx. disabling ATI's own processes, and then removing UAC and installing ATI Tray tools as admin on win 7. Upping the voltage FIRST before playing with RAM speed was the trick! kudos! im at 980:180:1.163v and runnig stable at about 304Mhs on each card ... woo hoo.
--edit: Namely: I just sent you a little token of appreciation. thanks much for the help. -John

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 monitor1) 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.
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.Re: Cooling middle cards in triple / quad card miners
This gets me on to problem #2 - I can't get any of the overclocking tools - AMD GPU tool, MSI afterburner, ATItool to work with my current crossfire config. I should have resistors turning up for dummy plugs tommorow, hopefully that will resolve that.
#1: remove the crossfire cable.
#2: I had mediocre luck (like tuning one card, not the other, etc.. ) with everything but ATI tools. Make sure you disable or uninstall all the others first (Including disabling ATI windows services) then reboot, disable UAC, and install ATI Tools as Administrator... this is assuming you have win 7. Also if you have issues make sure to up the card voltage before messing too much with the RAM or clock speed on the card (someone else on this board helped me with that). Once you do ALL that you should be golden.
my xfx 5830 has been running for 3 weeks at stock voltage 400mhz memory and 1ghz core. never goes over 68c i only get 300mh/s though with phoenix with phatk.
edit: tried worksize 256 and i got 10mh/s more! weird poclbm gave me less with ws at 256.

sweet... I hope I can do the same. ill be very happy if I can get 300mhs out of each of them 24/7 with no issues..
wow... im certainly glad I picked up a bunch yesterday from tigerdirect, hope they hold up to the abuse they are about to receive!. I really wanted the 5850's originally but they have been sold out since I started looking early last week, RIP.

I must be going something wrong. Every time I use Afterburner or trixx to move the Memory clock at all (anything below its default) the whole system freezes and I have to hard reset. 
I had the same problem initially and determined it was the full Catalyst Control Center running and not allowing this to happen.
disable it from running on start up and the problem goes away. Enable it again and the who system freezes pretty much instanly

thanks, I thought I had done that already. ill have to double check later, as im away from home and froze my rig up trying something remotely earlier today
im losing hashing time here gaddammmmnit. waiting for my GF to get home and press "reset" for me so I can get back in, lol. I need a pet monkey or something for this kind of stuff. Quote

different brands overclock differently. Almost everyone posting the 300+ scores is using the Sapphire card that newegg had on sale for $99-109.
The two I have are sapphires, the ones from newegg...

with new difficulty i am running my sapphire 5830 at 950/400 with 73C right now... seems stable and gives 290MHashs... don't want to go higher

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.

hey, im new here and dont know a ton, but I just set up a rig with 2x 5830's and they are running fine, but no crossfire. have you tried removing the crossfire cable? I dont think you need it for a mining only rig. I dont.
