Do All T42's Have 400Mhz Bus Speed?

[CRSO]

even with the Dothan processor? I have a T42 1.7Ghz

I want to find out which parts are interchangeable with my T43, all the way down to the RAM.

Bus speed in T42 (and T41) is 333. You cannot share RAM with T43

Really? I was reading Thinkwiki and it listed the Dothan at 400 or 533. Even the Banias was at 400.

Am I missing something?

...or CPU's.

T41's and 42's use a 400MHz FSB Dothan (or Banias), the T43's use a 533Mhz FSB Dothan.

Roger that... that's what I thought. richk said it was 333 and it really threw me off.

I'll tell you, the T42 1.7 400Mhz I just got seems right up there with my T43 1.8 533Mhz. Can't notice too much of a difference, even when running Sony Acid, Soundforge and / or Photoshop.

I thought the T42 would be a lot slower...

I believe that T42's runs with 400 MHz system bus (CPU) clock speed, but with 333 MHz type DDR1 RAM; see the Personal Systems Reference Lenovo ThinkPad Notebooks, 2005 to present - withdrawn, August 2007 - Version 326 - the ltwbook.
