I have upgraded My Lenovo 3000 N200 AUU from an Intel T2330 CPU to T9500 CPU (have Intel Chipset GM965) and added memory that runs up to 800 mhz, and upgraded from Windows XP x86 to Windows 7 64 bit, I get random crashes (not in safe-Mode though) and Speccy only gives me a Dram Frequency of 133 mhz. Can't figure how to resolve the crashes (upgraded the drivers) or how to get it to run at full potential (800 mhz) any thoughts would be appreciated.
