Probably been asked before - Volt Modding

[benjo]

Hey all

I've got my X800XT-PE Running with a Zalman VF900. Stock clocks are 520/560 and i'm running it at 560/580.

I've heard that these cards can be volt modded, and i've been interested for quite some time now.

I cant clock the card much further than that before i get artificats. Temps are fine, they never go above 50c load. I was mainly wondering what methods are there to volt mod? I know theres the pencil mod, but it seems inaccurate to me.. and i cant risk frying my card.

So are there any easy ways of volt modding, and will it allow me to clock my card further?

Thanks for any tips

p.s On ati tray tools, how many artifacts are acceptable? It says there are artifacts when i clock too high.. but i cant see them..

if you cant afford to blow the card dont volt mod

yeah it will help you clock a bit further - you can use pots i think - ill have a dig about for the mods, you might wanna have a look at xs, im shure they will have it somewhere

i generally ignore what it tells, I stare hard at the area and if you see the slighest thing out of place before say a minute, then i clock back a bit (with atitool, not tray tools)

Volt modding usually involves soldering a variable resistor / potentiometer to trick the card into giving the core / memory more voltage.

I've done it with a few cards. The Powercolor X850XT responded very well.

If you do it, I would recommend just doing the core:

1) Because this is where most of the performance gains are.

2) Because I've had too many problems voltmodding the memory, which is easier to b0rk.

Depends what your card looks like.
