That sounds kinda low for a 5830. I don't have one, but I know it can do ~275 when overclocked.
These two sites might help you find the best settings for you:

Thanks.  I've now used TRIXX to overclock to 950 and the megahashes are way up!  Whats the absolute maximum I can overclock this too without it being damaged?

You can definitely kill a card by increasing the voltage too much, but just increasing the clock speed should be safe yes.

Are you using -v -w128 flags? That increases my MH/s by 40-50. If you're concerned about damaging the card, downclock the memory to 500-600 to lower the heat output and increase the fan speed to 50-60%. This keeps the temperature on my 5850 in the mid-60s, which isn't much more than what it would be idle.

Just set core to 990 (was crashed on 1000)
Seems to work fine - 312 Mh/s

Btw - WORKSIZE = 256 works better for me that 128 at lest in Mh/s number

Cool, -v -w128 flags make it much faster as well! Smiley

What do they do/mean?


And also, I have just read about the modified version of polcbm which claims to be much more efficient, is this true?  Do I have to switch pool to use this?

Thanks

I get 300 with same card in win7 x64.

1) I clock it on 960. download last version of MSIAfterburner and search in google for MSIAfterburner.cfg that will allow you to clock more than 900.
2) here is my setting: -k phatk DEVICE=0 VECTORS BFI_INT FASTLOOP=false AGGRESSION=12 WORKSIZE=256
3) search in the forum have a patch that increase with 3-5%. But i cannot find the link now so you need to search and find it for yourself.
4) second patch is http://forum.bitcoin.org/index.php?topic=25135.0 i suppose it include patch in point 3.

Now you have all that you need to make a max bitcoins with your card.

Be happy Smiley

I have 4 cards.
3 on one mining pc and 1 on my webserver.
4 * 300 = 1200 = around 26 bitcoin per month on this difficult

Will I get better megahash if I use poclbm?  Also, it deepbit the same as all other pools, or is a different one better?

I am using Phoenix with the flags -k phatk VECTORS BFI_INT WORKSIZE=256 AGGRESSION=12 FASTLOOPS=false -a 7, seems to work best for me, gets me 450Mh/s out of a 5870.

I always get "no such option: -w" whenever I try to enter it as an extra flag....

Ahh, nevermind!  It was WORKLOAD= not -w...

Using "-k poclbm VECTORS BFI_INT AGGRESSION=11 WORKLOAD=128" works much better :p

I find I get better Mh/s with a workload of 128 than 256.

I also found that I have to run my overclock on the top 5830 lower than the bottom one so that it doesn't get too hot.  My top card runs at 870Mhz and my bottom card at 965Mhz.  This way, my top card runs at ~74*C and the bottom at ~70*C.  I get around 490-500Mh/s.

I know they're well below their max temps, but I'm going to play it safe until I get my new CoolerMaster case which should be here tomorrow.  My current case has crappy airflow.

Yesterday I had them both cranked much higher running in the high 70's *C and I was pulling ~590Mh/s.  I'll be pushing even harder with the new case Smiley

Both cards are 5830 Xtremes

I have my 5830 clocked at 980mhz
With the new guiminer and polcbm with the flags -v -w256 I'm able to get 315Mh/s. I vaguely remember reading that -w256 produces better results if your memory clock is low if not then -w128 flag was better.

I get 265-267 Mhashes/sec out of the box with no overclocking on Sapphire Radeon HD 5830's with phoenix 1.48.
Mild overclock at 960mhz, memory clocks lowered, voltage left at stock, fans at 80% and I'm getting 297 Mhashes/sec.

My buddy has the same card and he's pushing 307 solid, 980mhz I think...  and some voltage tweaking.
I didn't want to go there personally,  RMA'ing burned out video cards isn't fun. (Been there a few times with nvidia cards)
