Does CPU Stepping matter?

[maxpower054]

Will it matter if you are going to upgrade a laptop Processor with the same Socket and Wattage, but different stepping. Would it be compatible.

To be more specific, i want to upgrade the t4550(MO stepping) to a t7300 ( e1 stepping) .

Can this be done? they are both 35W, socket P, 65NM , just there stepping are different.

It really depends more on the motherboard of the system than the stepping of the processor. Those two have very different model numbers and unless the laptop shipped with a t7xxx series CPU in an up model its not very likely to support it, laptop motherboards have greatly reduced CPU support lists partly because they are prebuilt systems so they don't come with a full range of support and only support specific CPUs that the manufacturer thinks they might ship on that board.


What exact laptop are you dealing with? You may be able to find a CPU support list for it somewhere if you give the model number.

First i was interested in the t5800( also MO stepping) but with only 2MB L2 cach. The other CPU is 4MB L2 cach.

If I'm not sure, i may just go with the safer pick, the t5800.

You're confusing yourself that stepping matters. It only matters for the SAME CPU model.

What matters here is the model of the CPU itself, and whether or not the BIOS supports it. So far, I haven't found any info on that. Hopefully hunter can have better luck.

Ok, even though this post isn't about the t7300 specifically, the first reply says that it's supported, so I THINK you should be ok. May or may not need a BIOS update though. http://h30434.www3.hp.com/t5/Notebook-Hardware/Help-required-to-upgrade-HP-Pavilion-dv6700-processor/td-p/671043

my bios version is f.58


Which to pick though?

Core 2 Duo T7300

SLA45 (E1)
SLA3P (E1)

2 GHz 4 MB 800 MT/s 10× 1.0375–1.3 V
35 W


Socket P
FCBGA6

May 2007

LF80537GG0414M
LE80537GG0414M

$241


Does it matter which one i pick, whether it be sla45 or sla3p?

I looked at the service manual and it doesn't specify, so I guess either is ok.
