Upgrade to 2.2.3, that'll give you +93mv = 1.36v on the 3A. Then this is the hack directions for going over +93mv-

-Download ArtMoney SE v7.39
-Open Afterburner 2.2.3
-Right-click ArtMoney and select Run as Admin, then click continue
-Select Afterburner from the drop-down list in the center
-Set the core voltage (or any voltage you want to 'edit') in Afterburner to a number other than +0 (just to help narrow results) and click Apply. For this example, we'll assume you set the core voltage to +31mv
-Click Search in ArtMoney and enter 31 in the value box and then click OK, then click OK again
-Change that same voltage in Afterburner to another number, we'll say +63mv, then click Apply
-Click Filter in ArtMoney and change the Value box to the new voltage value you just applied in Afterburner and click OK, then OK again
-Click the top arrow in ArtMoney to move the top value listed in the left column to the right column (If you did the search and filter correctly, then the addresses for each voltage you should have come up with depending what you were editing are- Core = 00449000, Memory = 00449030, Aux = 00449060)
-Once you moved one of those into the right column, right-click it and go to Set Value, enter the voltage off-set you would like, then click OK, and notice that it's changed in ArtMoney
-Now, change one of the clock speeds so that you are able to click the Apply button in Afterburner, and then click it. You will now see the edited voltage jump to the amount you entered in ArtMoney
BE CAREFUL WHAT YOU ENTER. Make sure the voltage sliders in Afterburner jumped to where they were supposed to before you put any type of load on the card

so i finally got arround to doing an artmoney run at 14.1v and +260 core +450 mem it was a slight jump over my last run... still waiting for good temps outside to do the outside run devil.gif

Great score magiwizard.

I have had no success with any of the beta drivers recently, was testing out 310.70 last night but ended up going back to 306.97. Is this common and anyone else have the same experiences? Started off with weird clock drops while gaming....I think I saw someone else report that as well. Even on stock clocks, just running around like normal I would see a sudden drop in the clock down to 810 and of course a good lag in the game. Was really annoying, but then the entire game crashed. So I gave up on BF3 and went into Crysis 2...no clock drop, but didn't take long before that crashed too. Again, back on 306.97, running normal now and just like it should. I dunno....guess I just wanted to /rant.

I think I'm too stupid to overclock. frown.gif

I have AB opened with my stock speeds (Core Voltage: +0, Power Limit: 100%, Core Clock: +0, Memory Clock: +0).

I only increase my core clock by 50 and hit apply. Run Heaven @ default (or extreme?) settings and see if artifacts occur or it can run smoothly.
Now add another like +25 the core clock and repeat, right until now?

If it crashes, do I decrease my core clock by smaller steps (-1 to -5) and leave the rest at stock OR do I keep my +75MHZ core clock but increase something else instead? If it's the second option, what do I increase? And when do I increase core voltage and power limit - can I just crank it up to the max from the beginning so I only need to work on core / memory clock speeds?

I have read so many posts on OC'ig but none have helped me, sorry for being dumb. frown.gif

It's not stupid to ask questions, not at all. Everyone has got to start somewhere. Personally, I open AB, push the voltage as high as it will go, which is +100, take the power limit to +200%...and then I start trying to overclock the core. Just take it to a nice round number of +100. Leave the memory stock. Run Heaven, make sure it passes, if it does pass, then go a little higher with the core, up to +110. If it doesn't pass, then drop down to +90. Run Heaven again, it if passes, then go back up to +95, and try Heaven again, it if passes again, then I would call the overclock on the core good and stick with that. But of course if it does not pass then again go back to +90 and that would be the stable overclock for the core.
This is all an example of course. I started with the core around +150, benched with Heaven, found it wasn't stable, then dropped in increments of +10 until I was stable at +130, then once I passed Heaven at +130 I went back up +5, ran Heaven again and it passed, so my max OC for Heaven has been +135. I can go higher for 3DMark11, but my rock solid overclock on the core is +135.
Once you feel you've reached the max on the core, then start with the memory, going through the same process.

Thank you for the quick reply. I will try immediately. But one question remains for now, do I run Heaven with its default settings or should I crank up all the settings?

Sure no problem. That's completely up to you, benching on default or custom settings will have the same effect, they both will stress the system to the point of letting you know whether or not it's stable.

+REP'd you. There's one strange thing though: when I have applied my core clock changes and start Heaven (not the benchmark itself), it crashes. Then I just run it again and it starts normally so I can benchmark. Now I'm not sure whether my changes are dismissed or not, when it does run. In AB my changes have not been resetted, though.

Edit:
Here's what confuses me: I apply changes to the core clock, start Heaven and it crashes. Start Heaven again without any problems (which make me wonder, whether my apllied changes really were applied or not) and run the benchmark which passes.
Now I test the exact same settings with MSI Kombustor and it crashes after 10 seconds showing this error:

I will edit the Heaven error message later.
Heaven error message after every applied core clock change when starting Heaven:

If Heaven crashes, or any benchmark does, because of an unstable overclock it will not reset the settings you have applied in AB. You have to go back into AB and adjust then test again.
post #4450 of 7827
Strangely, my score decreases constantly with each core clock increase. This is another reason why I wonder, wehter my changes are applied.
