Note: This Northbridge with GPU was pulled from Lenovo G555, which had dead chipset due to badly soldered BGA. Chipset was replaced with new one and laptop works :) Second chipset is from severely damaged Acer Aspire laptop which has this chipset + dedicated Radeon HD5650M, i found no way to switch to chipset graphics.
