ATI Radeon X800 Voltage Modding Guide!

As you all know, it is possible to voltage mod your graphics card to improve the overclockability of its GPU and memory chips. However, unlike overclocking, voltage modding requires you to physically mod the card.

Today, we will cover the voltage modding techniques for the ATI Radeon X800 graphics cards. This covers both the X800 Pro as well as the X800 XT PE. Just remember to read through the guide and follow our steps carefully!

heya,

nice guide

but ...

you may want to include the Vddq mod aswell : http://www.madshrimps.be/gotofaqlink.php?linkid=2623



with this type of memory there are a few things to keep in mind:

- Vddq is best kept at 0.10V higher then Vdd
- more voltage doesn't always yield more overclock, one needs to find the sweetspot.

 

Thanks I will add that one

Here are the updates:-

• Added two Vddq mods - resistor method and pencil method.
  [*]Added list of required components and minor updates to the Over-Current Protection Mod (page 11)
  [*]Minor updates to pages 4 and 6.

Sigh.

Guess I'll be the first here to modifinihilate my card.

Card is a HIS X800Pro IceQ2 card. It reaches 560/560 stable at stock voltages (well, I haven't measured them yet but I assume the voltage levels are 'stock')

I'll keep you updated. Pray for my success.

 

wow. x800 volt mod. good article.

 

Good luck PhyberOptik!

 

Great Guide!! Thanks a lot.
BTW is the guide the same for AGP and PCI-E? I am about to receive a Sapphire X800 PRO PCI-E tomorrow and am just about to order some resitors...

Cheers

Shouldn't be a problem the PCI-E X800 layout should be identical to AGP X800 Mind showing us the picture of your card?

 

It's slightly different from the AGP version according to the picture from Beyond3d http://www.beyond3d.com/reviews/ati/r423/images/bb.jpg . So the measuring point maybe somewhere else.

 

i got a X800SE iam going to try this weekend.

it runs at 550/550 overclocked already without..

got water cooling on GPU and Copper RAMsinks as well so should be interesting what it will get with a bit more volts

 

quite odd results i must say..

i had my card in and out of my PC at least 7 times each time adding more lines (pencil method).

I put a HEAP on both the GPU and the Memory.

My GPU went from 1.404 to 1.450

and my memory didnt change at all..

I expected a lot more.. and i wanted my GPU volts up to 1.65 as i have water cooling..

though after and hour of doing this with so little change i gave up..

any ideas?

 

"Read the instructions. Start with a few strokes and check the voltage before adding more."


thats exactly what i did..

i am gonna rub em off and attempt the solder method.

fingers crossed

this is my 3rd card i have volt modded.. tho this is the 1st time i tried with the pencil method..

i prefer solder

 

Same here Sometimes it's very difficult to attain the voltage you want using pencil mod

 

ok volt mod done

Mem 2.25
Core 1.65


Core 630Mhz (425)
Mem 580Mhz (400)


I want more!!



X800SE btw

 

now if i could only find a way to unlock 8 pipes to 12 or 16..

hint hint
