i was about to increase the voltage of my card using Radeon BIOS editor
but i thought is it safe to increase the voltage( slightly or to max) without a pencil mod?

Its only safe if you do your research before hand and keep your clocks within reason as not to artifact or to push its thermal limits. if you do increase the voltage on your card I would suggest to invest in a quality AM Cooler to keep your temps down. And if you do the flash I also recommend to edit your existing BIOS to avoid bricking your card.

research as in inc the voltages step by step and checking the temperature?

As in know what you are getting yourself into before you undertake the task. You can see a great benifit from volt modding your card but it can be risky if it done incorrectly(not saying you would) but to be cautious. A BIOS flash is one of the easiest Vmods to undertake.

And yes take it step by step. You should be fairly safe pushing the 3D to the max allowed in a BIOS, just watch your temps. if you are good with a soldering gun then I would really look into solsering on a VR and pushing the voltage as far as your card can handle.

Before you so anything to BIOS voltages, makes sure you have a DMM so you can test any changes in voltage.

and wat do we exactly mean by bricking a card?

You should be relatively safe just doing a BIOS flash as long as it is executed properly. Make a copy of your cards BIOS using GPUZ and modify that one, do not try to flash it with a different BIOS as you could end up bricking your card. By bricking it I mean that it will be dead, inoperable, never to be bootable again. A few mV from a BIOS flash is not really enough to destroy your card so its safe to say that the only thing you have to worry about is your temps. Your temps will rise a little after the voltage increase and rise when you increase the frequency of the GPU,MEM, Shaders. I recommend to only raise the voltage and the fan spped in the BIOS and nothing else. Use Software to OC the card and dont OC in the BIOS

ok....i increased my voltage from 1.258V to 1.387V....

i did a furmark test...my score jumped from 3404 to 3464 at stock clocks...
and earlier my card had a max temp under load of 67 degrees, now it has 74 degees
and i have an option of inc my voltage to 1.43V also
have i been doing it safely and can i increase the voltage more?>

i acculy just bios volt moded the bfg card i have. I highly recomend you do so it gave me an extra 75mhz core clock. Make sure you save an orginal bios to flash back before rmaing.
