sweet! and those are on the outer side of the board right? the side furthest away from motherboard?
Also what about those 2 beneath those points...are those just negatives and not positives like the ones you highlighted?
Or could I measure from those bottom 2 also?
I dont think so i have had mine vgpu on 1.920volt on a mistake with no problem it can do a full 3dmark06 at 1.850volt and it is not getting hotter than 55c on my water

one 100kΩ Vr is fine and easy tunable
500kΩ should be fine too but it will give you crap Voltage control
I have one question the mod's are the same for both cards ? 2850 and 3870 needs the same Vr's and we solder them at the same points ?
i'am waiting 2x3870 for Vmod :p

Anyone else having issue to hit 1200mhz with 3870? mine has stock vmem 2v and mems are clearly overheating. 30 secs atitool and errors start to appearing, mems are hynix chips. cooling is crappy alu plate which i sanded clear and added thermal paste. gonna make good copper plate to cool them
ps: uploading mod pic asap

If i connect my 100kohm trimmer from the yellow point to ground,is that correct? Also what do i need to set the resistance to on the pot,before i boot up? My pot is a 100kohm cermet 22 turn
Thank you guys![]()
This is not my card which is a his3850 256mb,but the mod is the same for the 3850/70 is it not? apart from the vgpu measure points.
I just want to make sure i do this right.
EDIT-just measured vgpu while 3dmark06 was running,its hovering around 1.23-1.24v
I just put my trimmer on.It is set on max resitance and the vgpu as it booted was 1.24vgpu.So now i just need to lower the resistance on the pot a tad and see if it goes up on 3dmark06 from 1.24v.

well i set the vgpu to 1.36vgpu and tried it at 790mhz core on 3d06.It stomped it,this is with the core at 790mhz and my ram stock.It beat my stock score by loads.
It seems the 22turn trimmer i have is roughly equal to 0.1volt increase per 3 full turns of the screw.
The max temp while running 3d06 with the voltage on 1.36v was 53c using riva tuner to monitor it while i ran 3dmark.
My old stock score with core and ram stock was 9800
