getting 300Mhz @ 940Mhz/300Mhz
Not going to push up the core clock since running @ 1000Mhz probably shorten the life of the card.
Topic: 5830's, what mh/s are you getting? - page 3. (Read 7652 times)
I just changed the kernel.cl file that boosts about 3% mh/s. I'm now getting 278-279mh/s. Strange thing is I'm still getting a lot of rejected shares. I have vectors, HD5XXX, fastloop, and phatk checked in AOCLBF. I'm also using 128 worksize, 13 aggression. I'll try dropping aggression for a while.
~256mhash/s in my server with 2x 5830s, each at 875/1000
I've tried futzing around with AMDOverdriveCtrl but ran into stability issues with even minor tweaks.. the server they live in is the PXE host for my other miners so downtime is bad. They also run a bit warm, ~80C, but not outside my comfort zone.
Once i get a new board to throw these in I'll be pushing them closer to 300, but stability is a necessity at the moment.
I've had really poor luck with phoenix in linux on these cards - vectors, bfi_int and worksize 128 drops me down to ~205mhash!
Tips for improving hashrate without more gpu OC in linux appreciated

I generally use -v -w128 -f15 for flags.
With a single card, you can use sapphire trixx to overclock. With multiple cards, you can try doing the afterburner init file edit to allow more overclocking, or you can flash the cards.
I had some of mine flashed to 980/300 and I was getting alot of stale shares so I just wanted to test out different stuff.. I reflashed to stock and then I flashed again and made it so that I could go beyond 875 on the cards. Now I just use afterburner to oc the cards at boot to ~980 i think. This yields a little over 300mh w\ the new guiminer.

what do I add to the config file to overclock to more than 875?
ok cool thanks!

wow im only getting 256Mhash/s out of my 5830....how do I up it? I have overclocked witht the AMD overdrive and have -v -w128 as and extra flag on the older guiminer....new one is downloading now, running at around 48 C
I had one that is running by itself @ 1050 doing 325mh.
In my 3x5830 rig, all 3 are doing a little over 300. In my 4x 5830, I don't have any of the cards flashed or anything and at the highest default oc value w\ afterburn ( 875 ) they're doing around 275ea.
Using the newest 7-1-2011 release of guiminer on all, which provided a nice little Mh boost to all of my rigs.

I just picked up two XFX 5830's. One is dead and has to be RMAed. The other has some issues but is still able to mine. It'll also have to be RMAed but I'm mining it till then.
I'm getting 272mh/s.
I'm running phoenix 1.5 with AOCLBF 1.74. Worksize = 128
Still working on tweeking this. Just got 7.6% rejection with these settings.
