T41 400FSB 1.6 GHZ banias----

[T400plus]

will a 1.8GHZ Dothan cpu work qith my laptop.The VId voltage seems to be in a different range.The 2 and 2.1 GHZ (400 fsb) are documentaed to be as same VID as 1.6. why was this 1.8 different?

T41 2374-7FU,1.6GHZ,120GB,1.5GB

The Dothans you can use to replace the old Banias include:

Code: Select all

Model Number 	sSpec Nr. 	Frequency 	L2-Cache 	FSB	Mult 	Voltage 
Pentium M 710 	SL7V5 (B1) 	1400 MHz 	2 MB 	400 MT/s 	14x 	0.988/1.34 V 
Pentium M 715 	SL7GL (B1) 	1500 MHz 	2 MB 	400 MT/s 	15x 	0.988/1.34 V 
Pentium M 725 	SL7EG (B1) 	1600 MHz 	2 MB 	400 MT/s 	16x 	0.988/1.34 V 
Pentium M 735 	SL7EP (B1) 	1700 MHz 	2 MB 	400 MT/s 	17x 	0.988/1.34 V 
Pentium M 745 	SL7EN (B1)    1800 MHz 	2 MB 	400 MT/s 	18x 	0.988/1.34 V 
Pentium M 755 	SL7EM (B1)    2000 MHz 	2 MB 	400 MT/s 	20x 	0.988/1.34 V 
Pentium M 765 	SL7V3 (B1) 	2100 MHz 	2 MB 	400 MT/s 	21x 	0.988/1.4 V 

I don't see where you find your (wrong) voltage, they are all the same.

thanks.
I have with me a list of pentium M microprocessors i had search and downloaded from Wikipedia.
It shows
SL7EQ,SL7En,SL8U8,SL8U6,... against 745 and sl8QZ against 745A.
the volatage coumn is 1.276-1.34V. that is source of my query....

Hi,

Don't pick a 7x5'A' processor for a T40. Those are 'last incarnation', C0 microcode and may not be well recognized by the machine BIOS. So even if voltage will be no problem (motherboard adjusts to what the VID pins request), the microcode will / may be a stopper.

What IBM put in was SL7EN and SL7EM for 1.8 and 2.0 respectively.

If you want to be 100 percent on the safe side, those are your choices.

huh!, Motherboards adjusting to requested VID voltages?. This is great.
I would like to read this from available documents on the net.I have a lot
of free time ..for some weeks more... and I can put that to knowledge enhancement.
I also have a T400(4GB , p8600) which had just been used for playing that number puzzle,So I am feeling adventourous to play around with this T41(2374 7FU).
