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?
Pretty much spot-on. At worksize=128, between 180 and 250 the hashrate varies by a couple Mh/s, below 180 it drops fast and above 250 it starts decreasing slowly. By mem clock 300, worksize=256 is ~10 Mh/s faster and peaks at mem clock 354. But the worksize=256 peak @ mem clock 354 is still about 5 Mh/s lower than the worksize=128 peak at mem clock 186.

If this is not a dedicated rig though, then there is one issue with using mem clocks as low as ~200. Any load on the video card, such as playing video or flash, will lower the hashrate a lot more than at higher mem clocks.

Pretty much spot-on. At worksize=128, between 180 and 250 the hashrate varies by a couple Mh/s, below 180 it drops fast and above 250 it starts decreasing slowly. By mem clock 300, worksize=256 is ~10 Mh/s faster and peaks at mem clock 354. But the worksize=256 peak @ mem clock 354 is still about 5 Mh/s lower than the worksize=128 peak at mem clock 186.

I wonder why the hashrate is spiking at those values? It seems extremely odd to me that there should be performance spikes at such low clocks. I'd expect them to be at the high end.

If this is not a dedicated rig though, then there is one issue with using mem clocks as low as ~200. Any load on the video card, such as playing video or flash, will lower the hashrate a lot more than at higher mem clocks.

Yeah, I noticed that. I got around the flash problem by disabling hardware acceleration for flash. I also noticed that avi files had no effect on the hash rate but mkv's dropped it to about 50 Mh/s. I'm only downloading xvids from now on, they seem to play ok with AGRESSION set to 6 and I'm trying to avoid or disable anything that uses hardware acceleration.

Same observation with 5830. The only difference here is worksize=256 peak @ mem clock 354 is about 5 Mh/s faster than the worksize=128 peak at mem clock 186.

Sapphire 5830, model 100297L ($110 shipped)

I'm using the latest Catalyst 2.4 drivers (which include OpenCL), and using Sapphire TriXX to control settings.

1000/300, 1.2v, 65% fan.

phoenix miner:
-k phatk vectors bfi_int aggression=12

~310 Mhash

When I push it to 1033/300, I get ~320 Mhash.

----------

Edit: This has been brought up before in other threads (or so I've been told). While TriXX lets you adjust the voltage of the Sapphire 5830 cards, many programs that monitor your video card may NOT actually be reading the correct voltage.

For example, pushing the voltage from ~1.16 default to ~1.20 in TriXX may still show up as ~1.16 in GPU-Z, GPU Caps Viewer, HWMonitor, etc, etc - which gives you the impression that TriXX didn't work.

There is one program I know of that reads the voltage correctly. HWiNFO  http://www.hwinfo.com/

On load, it displays the voltage of 1.156v (1163 in TriXX). When I set it to "1200" in TriXX, HWiNFO then reads 1.195v. So I know TriXX is working.

Has anybody else had an issue w\ invalid/stale shares?

I noticed that my 3x5830 rig had a 1/7 ratio w\ my cards oc'd to 975/300 ( no voltage increase ).  I had around 7000 valid shares per card and then 1000-1200 stales :X.

Went back to stock bios and stale ratio went way down.

Just to update on my above post, I did this.

"Same observation with 5830. The only difference here is worksize=256 peak @ mem clock 354 is about 5 Mh/s faster than the worksize=128 peak at mem clock 186."

and ended up with the 312 Mhashes/sec on my 5830 Win7 box.  Tongue

*EDIT* Now I made this change #define Ma(x, y, z) amd_bytealign( (z^x), (y), (x) )

to phatk kernel.cl and am now getting 316 - 319 Mhashes/sec Tongue Tongue

Thank you. I'm probably a little closer to 313.5, but I don't want to have people get their panties in if they clone my setup and can't match it. Looking to push it higher, but as always, taking the rigs offline for tweaking costs more then it's sometimes worth with difficulty changes.

If I may ask, what's your ambient room temp for this mine, and how hot are the chips getting? Is your 'stock' voltage 1.163?

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?

How did you get your mem down that low on the 6870?  Did you flash the bios?

On the one running at 1040/340: 70-75deg F. Open comp case with a big fan blowing air in and the card's fan on 80%. By stock voltage I mean it's factory default (not exactly sure and i'm too lazy to reopen the remote session to check). This HIS card is a champ. Chip stays below 70c.

On the two sapphires, they are in a regular pc case and run a little warmer. They are running at about 80c with 65% fan.

Thanks for the info. My 2 5830's are in about the same ambient temp and setup (they are in a case, but I've got external fans going on them).

I wrote a little monitor that will help tell ya the info in a screen session (http://forum.bitcoin.org/index.php?topic=13855.msg188817#msg188817), or if you you have access to a terminal:

Code:
DISPLAY=:0.[whichever]; aticonfig --pplib-cmd "get activity"

Up to you if you're in the mood to do it Tongue

The HIS sounds nice. I'm going to try to replicate your results on my Sapphires next chance I get.

MSI Afterburner. Enable unofficial overclocking by editing the config file. Afterburner will appear to only let you take the memory so low, around 525 Mhz at first. Close it down then reopen it. Now you can take it down even lower, to around 260 MHz. Close it down, reopen it, set to 225 Mhz.

oc'd to 900 mhz on my core and memory is a stock 1000

anyone know what i should do to get even faster while staying reasonable? i spent most of the money i've collected the past few years since i don't get an allowance so i don't want to fry this card

also, swinging around from 265 mh/s to 277.9 mh/s

bring the memory clocks down to 300-350Mhz. Saves a lot of power and the card stays cooler. You should also apply the phoenix tweaks to speeze out more MH/s or try playing around with agression and worksize. My cards are giving me 285MH/s @ 900Mhz core.

294mhash at 950 core and 650 mem with tags -v -w128 -f15 AGGRESSION=12

You should really try using poclbm.  With 930 core and 190 mem I can get 297mhash.  By the time I bump it up to 960 core, I'm just over 300mhash.  I just use the standard settings for a 5xxx card on the GUI miner.  For whatever reason, 180-190 mem was a sweet spot on my card.  If the card isn't next to another one, I can get it up to 970 core, getting 312mhash.
