This also decreased my card power by 20W, and temperature by about 5C!
Currently running a single 5830 @ 920Mhz. Agression is at 7. At 11 I will gain a few more M hashes. I get 264Mhash/sec now.
Topic: Lowering mem clock to idle speeds SPEEDS UP Mh/s - page 3. (Read 39045 times)
Cool. Gained about 2-3M hashes by dropping it down to 339. 341 and 339 give me the same. Anything slightly higher or lower give me like 1M less.

So I did the tweaks to afterburner cfg file, and was able to lower my mem clock from 1000Mhz to 500Mhz, but the slider will not allow for more.
I see several of you posting going down to the 200, 300 and 400Mhz range. How?
I have a 5830 under Win7 64bit. Thx.
Slide it to 500, hit apply, close msi afterburner. Then when you open msi again it should let you go down lower.I see several of you posting going down to the 200, 300 and 400Mhz range. How?

+1
So far, i can't able to find a direct way to go 1038 & 360 directly.
The only way is to apply, restart & change.
So, you can't just start mining rig & go away. you have to change mem clk & after you can leave mining rig, until, it restarts again.

I laughed pretty hard when I read this...but I suppose it's worth a shot.
Strange development over the last few hours...was unable to stabilize that 970/380, so I'm back at the last known working config (960/390). Also, even running at the reduced core clock, I was seeing temps spiking at 82 and 83. Switched back to Phoenix...lost about 5 MHash/sec and the temps are back in the mid-70's. I've also got the big cooler running...the cats hate it, but they aren't making me any Bitcoins, last I checked.

Didn't get much of an improvement over Phoenix with straight POCLBM, but I did manage to stabilize the system at 970/380, which is nice. Hashrate is slightly higher when I'm using the computer, which is always a plus. I may have to go back to 960/390 at some point if this crashes a lot, but I'm up and running for now. I did briefly see over 300 MHash/sec right before my system crashed. :-/
I have a suggestion, but it may be hilarious. Instead of 10.7 driver & 2.1 stream, Try the latest ATI.
Thats 11.4 driver & 2.4.595.10 APP.
Here's the link, http://www2.ati.com/drivers/11-4_vista64_win7_64_dd_ccc_ocl.exe
But before installing it uninstall all ati/amd graphics drivers completely using Driver sweeper from www.phyxion.net.
I wish that helps u reach stable 300+ MH/s

Tried that already, didn't work
U sure, you installed only these 3 & removed catalyst control center?
ATI display driver, ATI catalyst install manager, APP 2.3 (or) SDK 2.1 & VC++
Some times even VC++ not necessary.
In Afterburner, after u set eula that u agree....
u will reduce mem clk to min 525, clk apply, exit afterburner & restart after burner.
Now u will see the mem clk is 525, but the slider will be in middle. Move it down further to mem clk u want & apply & minimize afterburner.
Instead of phoenix use poclbm new one.
Both give same hash only, but when i run phoenix, some times i FEEL some thing is wrong(don't know what it is)
Also [Tycho] mentioned that with his pool phoenix has some problem.

Can't hurt to try it, right? I used Kiv's GUI miner when I first started because my command line was super rusty (and still is, as evidenced by other replies I've made around here in an effort to be helpful). I think I can handle poclbm in the rough now. I'll let ya know.
Stales are reasonable on Phoenix with the newest version...no issues to report. The goal here is to squeeze some more MH out of this card, so I'll be back after I crash...errr...test my system.
If you guys see my sig at 0 MH/s, you'll know what happened.
I use Tycho's pool and phoenix and everything seems fine on my side

I can get my memory clock on my 5750 down to 575 MHz after restarting Afterburner once, but I can't get it to go down any further. Got tips?
By the way, I was able to push my core clock all the way from 700 to 870, gain about 40 MHash/s, and lower my temps by almost 20 degrees Celsius

Exit/close MSI afterburner completely
Open with notepad the following file
C:\Program Files\MSI Afterburner\MSIAfterburner.cfg
Go to end & u will see.

Wow, I dropped my 5870 memory clock to from 1200 MHz to 180MHz and saw an increase of 4-7Mhash/s. More importantly my temperatures dropped by 10C.
Don't drop mem clock below 300 Mhz. If u increase it to 300 Mhz, u will see more gain.
my trick is to use core clock/3 + 14= mem clk gives maximum hash.
If your core clock is 990, then 990/3 + 14 = 344 gives u maximum hash/s & of course 10 C drop in temp.
I remember you saying that when I first joined the forum a few weeks ago. No matter how hard I try, 960/390 is the best stable config I can get away with on my 5830. It drives me nuts. I can usually get it to run at 380 on Memory Clock for a bit, or 970 on Core, but it always just ends up freezing or crashing the drivers for the card. If I tried to drop my clock to 334 (per your equation), my computer would die outright. Win 7 64. What am I doing wrong?
If u installed catalyst control center uninstall it. It won't allow to go more & interfere.
Just install this 4 only for mining. Some times even VC++ not necessary.
ATI display driver, ATI catalyst install manager, APP 2.3 (or) SDK 2.1 & VC++
Still i am running at 1038/360 with 100% fan & temp <73C getting 298-300 Mhash/s
Windows 7 32 bit, Aero enabled.
Miner with -v -w128 -f10
If i run with -f1 some times system gets crashed, if i use youtube or accidentally open a site with flash...
I have the same issue with Flash...if you haven't, you can right click on a YouTube video, go to "Settings" and uncheck "Enable Hardware Configuration" on the Display tab (I know you know this, but lots prolly don't).
System specs for me:
Win 7 Home Premium 64-bit w/Aero and XFX 5380
Miner - Phoenix - running with -k poclbm VECTORS BFI_INT FASTLOOP AGGRESSION=7 DEVICE=1
(no hashrate change with smaller worksize after BFI_INT)
Current stable config @ 960/360; current temp 77C (varies between 70 and 80 depending on room temperature)
Current hashrate ~ 288-290MH/s
Software looks good...no Catalyst Control Center lurking about. Currently running SDK 2.1 and 10.7 display driver.
I may be at my max with this here Windows box.
I'd love to get a 970 or 980 stable config, tho...seems to get damn near 300 MH/s when I have it up that high.Also may be what you get is maximum & can't go beyond.
Default core clk for 5830 is 800, while 5870 is 850 & 6870 is 900.

At current I can go up to 1040 in MSI...no idea if that's wise, but the slider goes over that far.
