Ok, I'll post the script in a minute.
in for script running a 5830 @ 325 Mhash/s @ 850 MHz

I was actually using the standard script for poclbm, -v -w 128. I don't think that that was correct because that's deepbit said 650, and when I checked it half an hour later it said 450. Probably just a bad measuring script.

Rent my 800 + mh/s rig. PM me!

Ok I got things running with my 5830. Results so far: 305MH/s @ 990/355, Phoenix 1.50, Catalyst 11.5, SDK 2.4.

So you're going by the MH/s average that Deepbit displays? No wonder you're getting 325

Both cards on 1 motherboard no volt mods stock (1.163).
Very tempted to try and see what 1.25V will allow me to overclock the card to, STABILY.
GA P55-USB3 no separation cables. I have Sustained these speeds for about 2 days now.
I ran the cards solid at 1000/300 for about 2weeks, with no issues. Couple days ago decided to try Phoenix miner. After some trial and error found out that POCLBM gives me about 5-8Mhash more then phatk.
I have the Mobo on a tabletop, no case with two 120MM Fans blowing on the cards, with the GPU Cooling Fans at 80%.
from my experience on the Sapphire cards, the voltage cannot be overclocked without manually modding the board... if anyone knows differently please enlighten me.

Just built a system with 4 of these cards with a sempron 140 yesterday, built in a HAF-X case with a 1000w 80PLUS Gold OCZ PSU.
Modified the voltage of each card to 1.0v voltage via using RBE to edit existing bios, the 4 cards are running 860/280 across the board (for now, still stability testing, stable for over 24 hours atleast). Fan speed set to 60% across the board.. room temp of 26'c, hottest card about 78'c, coolest card about 50'c. Power draw measured from wall: 480w.
Seems like I could have built this system with a 600w PSU after the undervolting. System total is about 1060mhash/sec (~265 per card using poclbm phatk), build cost was about $900 before tax as I got each card for $103, but if I knew the power draw was going to be this low I could have opted for a PSU that wasn't $150.

Will one of you guys who are running at 300 mem clock and worksize=256 give 225 mem clock and worksize=128 a try, and let me know your before and after results.

I don't have any 5830s, but all 58xx cards should behave similarly. On my 5870s I noticed that below ~250 mem clock worksize=128 works better. In fact, the optimal settings I've found we're at mem=186, worksize=128. That gives a few Mhash/s more than worksize=256 and mem anywhere between 250 and 400.

The conclusion I came to with the 6870 was that the sweetspot was between 180 and 240. I was thinking the 5800s should be similar. There seemed to be a nice spike between those values, then below 180 the hash rates fell off rapidly. Did you find a similar pattern?

My best setting (5830) is memclcok = 300 with default worksize (SDK 2.1 + poclbm), which gave me 6 mhs more. Of course, setting memclock to 200 will lower the electr bill.
