if you're overclocking ... you're already losing your warranty
Not always. Some companies (like XFX & EVGA) will let you overclock and still honor your warranty.

doesn't matter, they can't find out you were overclocking unless you do something obviously stupid to show them you were.

Of course if you try to return a card that you damaged by overclocking, and this is not covered by the warranty, you would be committing fraud.

yes, but if it was not damaged by OCing, but I did OC it, I wouldn't feel bad by committing "fraud" to get a replacement... I never had to though, all the cards I've owned are Reference design XFX cards

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.

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 ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)

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.

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? ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif)

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. ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) 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.

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. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) 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. ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif)

Tried that already, didn't work ![Undecided](https://bitcointalk.org/Smileys/default/undecided.gif) 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.

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.exeBut 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

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. ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif)
