The motherboard that vaio VPCEB1S1E have dont support to overclock the gpu more than what you already try. The 5650 dont even run at PCI-E 2 but run at 1.1, i check it and the motherboard only support pci-e 1.1 i even instal a vbios for 1 voltage but still couldnt run more that 600Mhz and wasnt even stable but at 590/900 was quiet stable for me. So dont bother overclocking it more than that or overvoltage because it will not help
