Hi just seen this volt mod and overclock for a 7600 gs giving a core speed of 720 mhz. Has anyone tried this or any other volt mods on there 7600gs .

wow, nice find :eek:

sunlitsix · 2 Jul 2006 at 22:40

only needed 1.8v to reach 720Mhz :rolleyes:

im sure the card wouldnt last long if it stayed at 1.8v

nice 3d mark scores, although '03 seems low?

thats gonna be dead very very quickly, i think the GT has 1.2V going through core standard, and i think the voltmod takes it to 1.3 - 4 or something, 1.8 is too much :rolleyes:

tharr she blows.

want to volt-mod my 7600GTs but i don't want to kill them or anything, what core/memory clocks do you think i could get with small voltage increase on memory and core? (already runs at 655/835 at stock)

Cyber-Mav · 2 Jul 2006 at 23:12

will see 700+ with mod to 1.3 or 1.4v

i would do the mod if i knew how. need step by step guide.

sunlitsix · 2 Jul 2006 at 23:19

wouldnt be a very good mod, stock voltage for a 7600GT is 1.36v

ive got myn at 1.4v and thats at 680, so id say 1.5 would get to 700+
then again it depends on the core itself

Cyber-Mav · 2 Jul 2006 at 23:23

stock voltage is 1.36? hmm ya learn something new every day.

how do 1.4v mod then?

sunlitsix · 2 Jul 2006 at 23:28

just follow the guide on vrzone, every swip with the pencil increase the voltage a tiny bit. so a multimeter is required!

just messing about with the low power 3d settings in rivatuner, and so far im good for 690 on the core. either its just lower power 3d or the gpu voltage is higher than 1.4? ill check tomorrow with the multimeter
onto 700 now

Cyber-Mav · 2 Jul 2006 at 23:30

whats the lowpower gpu speeds do? does setting it the same as high power 3d make any difference to overclocks?

sunlitsix · 2 Jul 2006 at 23:33

well it seems to be!
only ran ati tool for 3 mins but its rock stable with no artifacts at 700/1700!
its never been able to do that before. cant wait to get 3d mark '05 going on it (wishes for 7.5k

) will do more investigating tomorrow.
the load temp is only 51°c btw

edit : well i dont know what to say! just ran ati tool again for 3 mins (i know this isnt long enough but still) this time at 710/1700. still no artifacts and rock stable! :cool:

the fillrate has increased a fair bit, stock 590 x 12 = 7080 / oc 710 x 12 = 8520. should give a nice fps increase

Hmm, my friend has a 7600gs, he needs an excuse to upgrade his card...I think trying this mad volt overclock should be a good way to do it

Cyber-Mav · 2 Jul 2006 at 23:53

hmm, last time i clocked the card to 650 core and low power 3d was at stock 560 the card froze up for about a minute in ati tool and then resumed working but at its lower speed of 560mhz. guess it had throttled.

i will try setting low power and high power 3d to the same speed and test again. will post back the results.

all i can say is that on my old 6800nu i card would always throttle if set above 375core. when i set the low power 3d to the same as high power 3d, the card clocked to 390 core with no throttling or problems at all.

will have to test this out on this new card as soon as the building work in my room is done. should be by wednesday.

sunlitsix, hows the overclock going.?

Gashman · 3 Jul 2006 at 13:34

damnit i think 700 on core would easily be attainable with both my cards with small voltage increase, and who knows about the memory its already at 1670Mhz, think 1800 would be achievable or even 2000?

Cyber-Mav · 3 Jul 2006 at 14:47

thats just crazy speeds. card would be unstoppable for its price. how much did yours cost you?

mine is an inno3d 7600gt cost me £97.50p delivered all in.

just got in from school so havent done any more yet.
i will just leave ati tool testing for stability/artifacts for at leas 30 mins before i push it any further

the memory on myn gives up at 1750, artifacts everywhere. same happend when i volt mod the ram.

Cyber-Mav · 3 Jul 2006 at 15:59

sunlitsix whats your core speed at currently and what voltage you giving it?

sunlitsix · 3 Jul 2006 at 17:30

it reset itself back to stock speeds

ive created a 1.5v 7600GT bios. so if anyone is willing to try it out and post results :

7600GT 1.5v Bios (Should be 2.24mb in size)

included in the zip file is the 1.5v bios, a copy of the original bios (at 560/1400), a copy of nibitor v2.9 and a copy of nvFlash to do the flash with.
instructions of how to do the flash are included. (if you find the guide isnt very clear either email me or add me on msn)
