T5250 to T8100

sja360 · 13 Jan 2008 at 12:13

Hi i was wondering my laptop supports the T8100 (800FSB 2.1Ghz 3MB Cache), i currently have a T5250 (667FSB 1.5Ghz 2MB Cache) both seem to have a TDP of 34/35 Watts, so essentially there should be no overheating issues? there is one thing that worries me is the fact arent some of the Core 2 Duo Mobiles soldiered into the board or am i talking rubbish?

The laptop that i have is a Fujitsu Siemens Pi2515 (Santa Rosa Chipset)

Also i have 2GB(2x1GB) of PC5300, can i put 2x2GB Sticks in? all the manuals mention "upto 2GB of PC5300 Memory" but i've read the chipset i have inside my laptop supports 4GB? would fujistu limit me on max memory for some reason?
cheers.

Laptop cpus are in a standard socket 479 zif socket with a locking screw that slides the socket into place. The cpus will probably be pin-compatible but does your BIOS support the new cpu? Maybe Fujitsu might release a bios update but don't hold your breath though.

i already know the laptop can take the T8100 and T8300 Mobile Penryns as it was stated in the manual

any idea about the ram side of things? i mean would it help having PC6400 (800Mhz) DDR2?

alright, isnt that abit back to front having the out of sync (1:1) with the FSB? i know there probably isnt that great a performance difference but still...

That's the way it is, memory interface runs at that speed. Look at 1.1.2
