6850 pencil/voltmod help

post #1 of 42
Thread Starter 
Tried pretty much every software solution (My old MSI 6850 worked fine in AB with 1.4V 1100/1200 but was having blackscreens out the box), as well as MANY different bios' so don't even bother with any of it.

In case you're interested, here's what I tried; (PLEASE SKIP OTHERWISE)
1- AB/AB beta/voltageunlock/enabled voltage/unofficial unlocking and the user statement and all that
2- Trixx
3- Several 6870 bios (found ONE that worked @ 1.175V but was having multi-monitor issues)
4- XFX BE bios - works but no voltage control
5- Used RBE to edit GPU voltage register from 1.15 to 1.2v, 1.3, v1.4v - gets into Windows but no voltage change.
6- Used RBE to edit GPU voltage register from 1.15 to 1.2-1.4 AND the performance clock state on both a regular xfx and xfx black edition bios (1.15v shows up as the boot state for the regular bios and in the normal #3 spot for the black edition bios so I tried both) - If you change the voltage in the "perf" clock state, I get a blue screen while loading into Windows - and yes I have overdrive disabled.
7- every possible combination of all of the above - nothing works

So I'm down to pencil modding the VRM (for the core, I could care less about the memory). Could anyone show me where to shade or should I just do trial and error? I want to get at least 1.3v and hopefully 1.4v or more. I am on good water cooling so please no comments related to why/danger,etc.

I would just return the card to the local store and order another but unfortunately XFX had little impossible to remove VOID stickers on the heatsink screws, so I'm not sure they'd take it without penalty.

this mod is for solder and a VR..not pencil. There may a point to pencil to for GPUv change..but you would have to trace it from the green points on the pic above.

Those two phase ADW7088 ICs are generally used for memory. Are you sure that's the GPU VRM IC?

Also, ADW IC's are crap and die easy.

I believe I have the same card as you Product ID ends in ZNDC and XXX Edition or overclocking edition.

Which bios did you flash to obtain 1.175 volts I'm not looking for a huge overclock just stability at 939 core+?

I also only use one monitor via HDMI so I believe I'd be alright, unless you left something out.

Was going to PM you but seems its disabled for new members.
