Ok thanks I thought that the mem wouldnt help much and its only DSP mem so not the best OC mem if it had been Hynix, it would be much better with the pics i will take them tomorrow but thanks alot for now.
i thought that the Pm 25LV512 would be the VMem Controller
i also have a Guide for the Gigabyte HD 5450: http://www.overclock.net/t/696166/gigabyte-hd5450-vgpu-vdimm-mod
But its a different layout also i will check the resistance between the Pins it was resistance*20=Poti., wasn´t it?
