I'll have these done soon enough...have to practice soldering smaller areas first.
High res, my ghetto paintbrush version. Makes it easier to see the surrounding areas.



Here is the one from TechpowerUp. Big thanks to W1zzard. He's the man, as well all know.
VGPU VR mod

VGPU Pencil, <=1.4V


VGPU pencil >=1.4






As always don't fry your card, blah blah blah
Enjoy

Good job +rep

What kind of clocks could I expect out of 1.4v?

850ish I'd say, maybe 900. As you go past 1.4 there are massively diminished returns.

mth91

I got it to 830/1075 with 1.34v.

Awesome. I'll add you to my spreadsheet in the 4850 discussion page.

This is sweet. I'm going to try the pencil mod on the core. If I get that right, Ill do the memory too.

EDIT: If I may ask, mth how many strikes did you do across the resistor?

mth91

No, unless you have a good cooler on it, don't do it. That's bad news. Check my volt mod thread for my temps. I have a duorb and a 130cfm fan on it, with another fan blowing on the vrms, and heatsinks on the vrms, and i'm still having 99c temps on the vrms. The core is 80c. That's at 1.35v. I'm gonna drop the voltage some though right now.

Well I'm probably going to do it once I get an HR-03 GT and strap a fan on it.

mth91

Yeah, that's a much better idea. Your vrm temps will be high though, so you're going to want to buy a set of mosfet sinks. Go to svc.com, they have a set.
