HD-687A-ZHFC XFX 6870 Voltmod

post #1 of 18
Thread Starter 
I am looking to volt mod my 6870 because it does not have voltage control and I'd like to get some more power out of it. Anyone have any experience with this card? There are pictures of the back of the PCB on Newegg that allows a decent amount of zoom. Anyone see if this is possible from the backside of the board?

It doesn't have adjustable voltage control.

As I said, it doesn't support it.

Yes. I even changed the voltage in the ROM and reflashed it. This card does not have adjustable voltage control on the card, it needs to be modded.

There maybe a guide modding your card, but I don't think you can use the stock cooler you may need a better cooling and it's not good
for daily use.

+1 this card has nasty reviews for heat.

But that doesn't mean automatic-no.
What are your temperatures? idle/load?

85c load but that's with Furmark 1080p with Xtreme burn-in. Gaming it doesn't get anywhere need 80, more like 75c tops.
