ATTN. 7800GT Owners

post #1 of 8
Thread Starter 
I've modded the BIOS for my XFX 7800GT to raise core voltage from 1.4v to 1.5v and already have the floppy ready to go and flash to the new bios. However, I'm worried that my card may die from this increase, as I have heard from speculators that after 1 year it will croak.

Does ANYONE here have experience with vmodded 7800GT's? How long have they lasted? How much boost do you get?

ALSO, does anyone know of a mem pencil vmod for the 7800GT? Someone on here told me there was one, but I don't know how to go about it...

the time the card will last all depends on how much you overclock it with the added voltage and what kinda of cooling solution you use

High volts and temps is what kill a card, flash at your own risk......

Personally, I wouldn't risk a piece of hardware thats worth about $200 just to gain a few extra FPS in games or a few marks in 3dmark.

I do agree with you there... But this is all in the pursuit of every last ounce of power I'm so addicted to overclocking that I can't leave anything untouched lol

I'm very on edge about doing it because I wouldn't get a new card for a decent amount of time :-\\ but maybe after my next build, I'll attempt this vmod

I volt modded my 7800GT and never had a problem with it. The key is to keep it cool. I wouldn't do it if you only have stock cooling. Get a Zalman VF900. I had water on mine

Yea I was thinking of ordering one since they are down to like $33 on newegg, but I also wanted to cool off my GPU with an AC Freezer7 & FM91 mod...So I'm not sure yet. And by the way, my max load temp with stock cooling on my 7800 is ~68°C (running RTHDRIBL), it never goes above ~55-58°C when playing CS:S or FEAR.

How long did you own your 7800GT for and how long was it voltmodded for before you got rid of it? Any noticable wear and tear on the integrity of the card after the mod? Sorry for the questions, I'm just being precautious.

Oh, and did you just do the BIOS mod? Or was it a hard mod?

My old 7800GT is in my GF's rig now but it spent 18 months volt modded and overclocked @ 510/1200 in my rig without so much as a hiccup.

Basically if the card can handle the overclock it will be just fine, if it can't? Well i think you know what to expect, and that is the gamble you take with volt modding

Oh and hello everyone
