This voltmod applies to all X1900 series cards using PCB #A520031-50 with VDDCI support.

These mods are designed for users of extreme cooling solutions who need more voltage than can be set via software with ATITool for example.

Looking good.

I would like to do this but what amount of performance increase will I get with this?

Also I have never done anything like this, on a scale 1-5 how difficult will this be?

One last thing, you show sodder points, and the line to another point, what gets soddered?

Sorry just confused. Thanks!

with air cooling you will probably gain nothing .. these mods are mainly interesting for extreme coolers.

well, is it the same mod for a x1950XTX card, or does the 1950XTX need another mod??

Has anybody with watercooling done these? 800 Mhz possible?

It looks like for X1950XT these mods work too.

My best without any kind of volt mod or change in voltage settings was 754 mhz on the core.

This was with the core under water.
