Upgrade Sony Vaio VGN SZ230 Processor
If you have Sony Vaio VGN SZ230 with T2400 socket M then you’ll be able to upgrade it to T7200. This could be surprising as the original VGN SZ 230 machine was 32-bit and will be upgrade to 64-bit OS, but it did. Actually you can set max memory to 4GB, but if use it on 64-bit only 3GB is available to get, most likely it cause of BIOS / chipset limitation.
Sony Vaio VGN SZ230 CPU upgrade to T7200 is benefit to boost the CPU faster from 1.66 to 2.0GHz and quieter. And the best thing, all is works with just removing the old CPU and put in the new one.
The VGN SZ-2xx has Intel 945GM Express chipset and logically, it’s compatible with T7200. However, while the processor is logically compatible, you need to make sure that it is a Socket-M so that it will physically fit. It seems that the memory controller of the SZ2xx is limited to 32bit, and thus you will only be able to address a maximum of 3 GB of RAM.
