Hi,

Volt modding a gfx card is a relativley new thing to me and haven't fitted a 3rd party cooler on a gfx card since my 9700Pro/Arctic Silencer combo.

I'm looking for a effective and relatively quiet cooler for my 7600GT AGP, and some advice on volt modding it. I currently top out at 664Mhz on the Core and around 750 on the mem. Looking to hit a nice 4500-5000 on 3DMARK06 with it (current score 4003) I've seen Core @ 750 using a volt mod so hoping for the same. Not sure if ramsinks would help the mem overclock?

Price wise - quite cheap as I know I could sell my 76GT AGP and buy a PCI-e x1950 for probably the same cost as a multimeter, cooler,etc. (it's probably cheaper to upgrade actually and would give better results!)but where's the fun in that........:p

Also, I'm well aware that doing this is dangerous and will void my warranty.

Any advice or suggestions are very welcome, thanks.
 
get the zalman vf900, awesome coolers

voltmodded my 2 76gt's, one did 750/2000 other did 850/1900 :) ramsinks will help a bit with the mem, expecially as the zalman has a downwards blowing fan (and thsese come with the zalman cooler)

They are a bit pricey, look for a 2nd hand one
 
yes, volt modded the mem and the core (only use a pencil mod, so it was completely reversable) the vf900 is exceptionally quiet, even comes with it's own fan controller if you are not happy with it :)

Where did you find your volt mod guide?
Click to expand...

Googled it, can't remember the name of the site now :( You have to be fairly specific with make/model though.. (mine were xfx and pci-e, so i would guess the 2 resistors i pencilled are completely different to yours...)
 
Yeah, having problems finding a Gainward/Xpertvision (think they're the same??) 7600GT AGP volt mod....

Did you use a multimeter to detect your voltage after the mod or can software detect it for you?
 
Luckily i have a mate who used to do a lot of electronics before he became a pc engineer, and he has a multi meter, so yeah, i used that, although i was measuring resistance, not voltage (lower resistance = more voltage)
 
Don't think you can adjust the voltage via any software, unless you can do it through the bios of the card.
 
just had a look at nibitor. Do I
a) change settings and re-flash my existing BIOS
b) try and source a verified working and compatable BIOS?
 
Anyone had any experience with nibitor? If I try and flash my BIOS with another VGPU value would this increase the voltage or is this impossible? The only thing is the values have '??' next to them, i.e. It doesn't tell me what volatge I'd be getting (assuming this method works?!). However, I'd assume that if this did work, the voltages would increase but would remain within the parameters of the maximum voltage (I'm thinking these are presets??) I have three choices:

1. ??
2. ??
3. 1.3V - Currently Selected
4. ?? - I'd flash to this (guestimate that it'd be 1.4V)

Any ideas?
 
i pencil volt modded mine to 1.7v (direct reading from the card) I would assume the '??' = o.1v increments, so even if it was in the other direction on your list, the top one could be 1.6v, so i would assume these would be safe, however there is always risk when flashing things, power failures etc.

I did briefly look into NiBitor, but i couldn't specifically fins the values, and thus didn't bother, as it would have been a rather random guess, and i like to deal in better percentages than that... :D
 
I've been advised to look on a forum that's dedicated to nibitor and the like. I may post back in this section with any values I find that can be of use....

EDIT- forgot to say thanks for your help!
