Topic: Good Speeds on Sapphire 5830's 311.4MHash/s - page 3. (Read 24138 times)
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.
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.

Trixx software version 4.1 let us change voltage at 5830 ...
(that is what the software says ...=) i don't know if it really change it !

where did you find 4.1, because on the official page i can only see 4.0.1

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.
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.
So you're going by the MH/s average that Deepbit displays? No wonder you're getting 325
Ok I got things running with my 5830. Results so far: 305MH/s @ 990/355, Phoenix 1.50, Catalyst 11.5, SDK 2.4.

Ok, I'll post the script in a minute.
in for script running a 5830 @ 325 Mhash/s @ 850 MHz
2x 5830 Sapphire with GUIMiner "-k phatk VECTORS AGGRESSION=12 FASTLOOP WORKSIZE=256 BFI_INT" getting ~290Mhash/s per card 930/300 with open case and a fan blowing on it, staying at 60c.
quoted so I can find this later.

Thanks I will try that when I get home!
These ATI tray tools where do you find them? Is it better or about as good as Trixx?
I found them here.

in the Performance tab, first option.. overdrive or something like that

I know other people are getting more, but this is what is stable and has the most yield for me at this time. (And I am way happy with 303 MHash/s as compared to my 6970s which cost like >$200 over the 5830s and barely get 78 MHash/s more...)
The question I have is does anyone know of a OC'ing tool that will handle multiple GPUs?
YES!!! why is it so hard to find a simple concise answer about over clocking multi gpu WITHOUT crossfire?
Does MSI do it ?, I know trixx dosent cause Im running it
MSI seems to have a feature when pressing the "Settings" button that allows you to "Synchronize setting for similar graphics processors". My issue is that I am working with multiple type GPUs in one rig and need to OC/change the settings for the 2nd GPU or 3rd GPU if I decide to go crazy with an extender cable to bring out the PCI-E x1 slot. Not sure if I want to go down that road yet for the 3rd. I'm trying to see how much savings I would have just running multiple rigs vs. trying to pack more GPU then two on 1 motherboard. Stability and cooling comes into play, and having to get 1000 Watt power supplies. I guess I'm just old school and like my systems in closed cases with mega fans for air flow. As long as I keep them under 75 to 78 degrees, I think I'm good.
So any OC'ers out there know of this magical tool we seek?
What the hell are you talking about? with MSI afterburner you can easily select exactly which GPU you want to adjust, from the settings menu. There's no need to use "synchronize settings for similar gpu".
Guys... MSI Afterburner supports 2+ cards.
In the settings you can select the card to adjust.
And if all else fails, set the clocks manually with AMD GPU Clock Tool (this is what I use when my other tools fail).

If your only using 2 Cards, Use ATI Tray Tools.
It allows you to apply requested clocks to 2 Cards, I have not tested it with anymore.
xFire is a bad idea, you loose precious Mhash's

HELP US!!!! might be worth some coinage!!!!!!
I am in this same situation 2x 5830's one at 304 mh the other at 260 mh they are nto crossfired and I can only get the OC setting to apply to one of the cards
Perhaps we should throw together a bounty for a detailed explanation on how to overclock multiple cards on the same board without crossfire. I only have 2x 5830's but i would thrown in .5 btc.
dumb Question but, If i were to attach the crossfire cable, and then disable it within CCC, and load trixx to OC both? would the cable merely being their aide in the duplication of the settings? or would be disabling crossfire make the cable and setting adjustments pointless?
I used to run two seperate boards with both 1x 5830 and got around 290M/s each.
Now, I tied them together with crossfire on a single board, getting 234M/s max on each. Which is bad.
I hope to put in some VGA-dummy-plugs tomorrow, maybe the crossfire is messing things up.
