What motherboard My R61i has ?

Hello.
Basic stuff. What is fastest cpu to my R61i unit? There is no fru sticker under memory modules. I found printed numer on the bottom cover 42w3859. I'm guessing this laptop has an merom?

Nowadays t9xxx with slower fsb are dirt cheap and I could possible use more cpu speed.

Yours is a Merom board with a 533MHz CPU.
With Middleton's BIOS you can first try 800MHz CPUs like T7100/T7300/T7500/T7700 before you go for Penryn.
If they run, then get a Penryn T9300.

Ok. It has T7500 in it and it works fine. So I'lll go for T9300.
Thanks.

T9300 arrived today and man it is whole different machine now. I was amazed how even youtube 720p worked in full screen (low res panel).
