Hey guys, i have a question, how i get more voltage and power limit for best overclock in my msi gtx 680 lightning¿? i have a hard limit in this (see the picture)



this limit dont let me go.

what do you recomend Shperax. I want to play Crysis 3 at that speed frown.gif

I think its always best to lower your core to something stable and go crazy with your memory clock. +100 Mem clock makes more FPS difference then core clock +25 more say.

If i was you i would put it at 1350 core then try and get your mem as high as you can. Remember to drop down the slider in 2.2.3 and max out the mem and aux voltage and your mem clock should go very high

You should be very pleased with how many more frames you will get rather then focusing on the core

I would also use the Valley benchmark. its free like heaven and i feel like if your stable in valley your stable in everything for the most part.

Like with my OC i just made it barely squeek through Valley and ALL my games work perfect

ALSO remember that if your driver crashes or you fail a benchmark run to exit out AB and re open it or the OC won't be in effect. Also remember to change back the voltage slider to +100 and hit apply every time you restart AB or your PC so it goes back to +93

And as far as temps go. Make a custom fan map in AB that is a straight line from 0,0 to 100,90
100 being all the way at the top and 90 across
(you can delete the extra map points by clicking on them and pressing dlete as you only need 2)

Did you flash your BIOS because my AB 2.2.3 lets me go straight to 300 power limit.

I had a weird bug where i had to restart and re-install AB a few time before it would let me raise the slider to 300% and also if the voltage OC is working properly when you hit apply you should only beable to get +93mv

I would try completely uninstalling AB. restart. re-install AB. let it detect settings and restart for you and then try again

(i think the bug had something to do with having the new version of AB on my PC before i got 2.2.3)

I cant buddy, i try reinstall 5 times and nothing, i cant understand my LN2 Bios is 80.04.28.00.3A (unlocked LN2) and dont let me use more voltage or power limit frown.gif somebody help me?

PD: do you think that should change to OLD Unlocked BIOS 80.04.09.00.F8 ?

If your card wasn't one of the 1st 5000 cards made then when you flash to the F8 bios it will be all funky colors and lines. You can hardly see to use the backup.rom you made

It really should be able to go to 300% power limit with 2.2.3 few things i would try

When you un install AB the question it asks is weird. instead of delete all data to do with AB... Yes/No it says something like do you want to keep old AB data Yes/no
So you want to say no.
Then after its gone use something like ccleaner to clear the registry files if there are any
then try installl again
or
Re-format your HDD with a fresh install of windows

Yes i tryed it, unistall ab, when ask me, click NO, and i go to C:\ and i delete msi afterburner folder, and finish with ccleaner...

but no luck, you recomend me reinstall windows?

Assuming you truely do have the 3A Bios flashed on from the Page 1.
yes reformat your HDD

It really can't ever hurt to do that anyway. Makes your PC all new and fast again.
Thats all anyone really ever does to fix any software issues for PC.

then put on AB 2.2.3 and if it doesn't go to 300% after that.....i have no idea whats going on.
Because if its unable to go to 300% the voltage adjuster looks like its working but probably isn't actually adjusting the voltage

Other thought im having are things like
did you flick the switch on the GPU itself to the LN2 BIOS that came pre installed and you flashed that BIOS or the default switch position BIOS
^^^^
i don't even think that could affect anything anyway but its the only thing i could come up with.

This is very useful after doing a re-format (after you finish all those damn windows updates)

just check the stuff you want and hit Get installer

Check again my picture, in the picture you can see the bios model, and this bios come with the gpu, i dont flash nothing.

EDIT: Already can get 300% of power target, but now i want more voltage, only can use 93+... i tryed with all voltages maxed out (core voltage, memory voltage, aux voltage) and core clock 190+ and memory 500+ but crash... same voltage with core-180+ memory-480+ and crash, core-170+ memory-470+ and crash, core-160+ memory-460+ and crash, DAMN.

You should never max out all voltages and then look for the highest OC. That's backward. Pouring in max voltage to every setting will NOT improve your OC. Too high voltage makes it unstable.

Here is how to do it. First, set aux at -100mv, mem at -50mv, and core at +0mv. Now you're ready to start. Try a modest OC like core +0mhz and mem +250mhz. If that's OK, bring up the core freq first, to like 20, 50, 70, etc, and increase core voltage a little at a time as you go, like +25mv, then +37mv, etc. Leave aux and mem voltage alone for now.

You will probably not need to increase aux above -100, or mem above -50, but stock voltage on mem is not unusual. You should be able to reach a nice OC of +300 to +600 mhz mem using -50 mv or stock mem voltage, and +40 to +80 mhz core using +25 to +50 mv core voltage.

Once you dial that in, you are ready to go for benchmarks, using higher core freqs and voltages.
