Hi Blencogo

Thanks for your answer

Notes on Intel AW80576GH0463M

Bus frequency is 266 MHz. Because the processor uses Quad Data Rate bus the effective bus speed is 1066 MHz

I fitted this CPU and it is a match for the existing one, however on boot everything engages but I just get a blank screen.

I'm baffled as to why

Sony Vaio VGN-NR21M - PCG-7112M

VGN-NR21M

noreplyforum@eu.sony.com — Thu, 08 Mar 2012 08:59:27 GMT

Just purchased this Vaio on Ebay and was wondering if anybody out there knows if I can upgrade it.

At present it has the standard Intel Centrino Duo 1.66GHz CPU and 2GB DDR 2

I have an Intel Core 2 Duo 2.13GHz CPU Socket P to instal and want to upgrade the memory to at least 4GB

I don't know if this Vaio Model is only a 32Bit Motherboard or is cabable of 64Bit and will be upgradable.

Sony's sight does not offer much in the way of information regarding this and also has poor support issues in regards to questions.

Thanks to anyone who can shed light on this.

Regards
