Sony Vaio VGN-AR790U Mod to 1066Mhz processor

[vonfeffer]

Hello there, I'm aware that there is already a modded BIOS for this machine. But I'm also a Thinkpadder and found out they managed to make a BIOS mod to accept the Core 2 duo Penryn 1066Mhz generation on the T61 model. The T61 model uses the same chipset the Sony does, and since the T9500 is not being able to keep it up with my activities I was wondering if you guys could make this mod so I can install a T9900 processor on it...

Heres the source:  T6x - Manual: Using FSB 1066 CPUs incl. Core 2 Quad in Thinkpad T61 + GPU undervolten | ThinkPad-Forum.de

Thank you so much!

Your laptop is based on PM965. So you can't use CPU with FSB=1066 Mhz without a hardware modification of laptop's motherboard.
