SAPPHIRE Radeon HD 5870 1GB - Pencil Mod - Non Ref Card

Check it out for all of my AMD overclocking stuff

This is the card i used:

I picked up my digital multimeter from Radioshack. The pencil is a 2B art pencil, better graphite for pencil modding than a regular HB2, but that will still work too.

how did i do it on gigabyte version ???? thx

[Slappa]

@idan124 Unfortunately it depends on the card. I do not have your exact card, so I couldn't tell you. It depends on the IC/VRM's your card uses.

Can u undo this , or this is permanent mode? I got an 5870 ref design and want to go over 1.35v to around 1.6v how can i do this accurately?

[Slappa]

@2007vitaly It is not a permanent mod, pencil mods can simply be erased.

Pencil mods are not accurate whatsoever. You would need to do a permanent solder on mod to be accurate. 1.6V is too much for 5870's to handle

[idan124]

@Slappa maybe we can talk somday on video and u well help me???

@Blackout9550 There are resources all over the internet where you can type in the chip number and get a profile of the semi-conductor

@crabid Absolutely, but the correct resistor would have to be identified
