Works on VT1165 / HD4890 Black Edition

[der8auer]

Just used the eVc for the first time and it works great.

 

Card has two VT1165 ICs. One for GPU and one for the memory. Somehow I can only change the GPU voltage at the moment. Not sure why.

 

For VT1165 soldering use Pins 36 (SC) and 35 (SD)

You do not need the 2 EVC units

the 2 VT1165 they operate on the same SMBus

You need to have elmor to fix EVC software

either run the two different addresses or run master slave system

in fact hd 4890 dont need at all any hard voltmod´s because VT1165MF can be operate software:)

der8auer, can you set higher than say 1.5 vgpu? For me max is 1.4 vgpu on a ref hd5850 and for another swedish overclocker, 1.48 was max on a 4870. There still seem to be limits in place.

For reference HD4890 you only need GPUTool for vGPU and vMEM, but I guess it's still good to have support in evc.

Yea I could do 1,6 Volt without any problems.

hi der8auer....i solder evc on my 4890, if i use GENERIC vf1165m on evc software i have only 1 volt to tweak(but this don't work), if i use vf1165 svid i have 4 volt to tweak, and second voltage is for vgpu......

 

but i don't know what do the other:

 

1°=???

2°=Vgpu

3°=???

4°=???

 

did't you know what they do?? thanks

They are for different power states reported from the GPU. Is the second voltage working in both 2d and 3d?
