xps m1530 CPU Upgrade

Hello All,
I have recently upgraded my cpu from a 1.6 to 2.5. My question is the Bios.
Do I use the latest for the 1.6 or use the 2.5 update for the Dell m4300 from which the cpu came from?

 

They're two different machines from Dell and the BIOS flash for one may not work for the other. Another consideration is the FSB speed. You may not get the 2.5 GHz from the swapped CPU. it will be throttled if it works at all.

 

it there anyway to detect if my system excepts the upgrade to tell if it's being throttled or not? fsb speed are the same.

 

After you swap out the CPU, if the computer goes into POST, press F2 to enter Setup and see what it reports for the CPU clock speed.

 

it says: cpu 2.4
1.4 min and 2.4 max speeds

 

looks as if the mother board is compatible....
are there any warning I should know about concerning the Bios update between my
(xps 1.6) m1530 and the m4300 2.5 Bios?

 

A general rule for BIOS upgrades is if it works, then there shouldn't be a need to upgrade it. So unless there's a new feature promised by the BIOS upgrade that you need or there's a significant bug that it fixes, if it works you can just leave it as is.

I think I don't really understand the question, are you upgrading a new laptop with a CPU from an old laptop?

 

yes I upgrade the cpu from a 1.6 to a 2.5.
my understanding is that bios controls the power, and performance. If this is so, I want the chip to run at it's peak.
Can anyone answer this and the initial question about which Bios I should use?

 

If you want to upgrade to the latest BIOS, you should use the one that DELL provides for your specific laptop. You cannot upgrade one laptop with the BIOS from another laptop. Here is the link to the latest BIOS for the XPS M1530: http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=P0FRC

 

cool... that's the answer I was looking for!

 

As you say, BIOSes are model specific. I've got a Dell Precision M70 but, the System board would also drop into a Latitude D810. The only difference between the two models IS the BIOS.

 

Please delete. Duplicate entry.

 

I agree that the Bios are model specific, due to a lot variable inside the board. Like for instance in my case, the boards are the same ,but the GPU's and CPU's are different.
Now please correct me if I'm wrong, but isn't it the Bios that control's how much power a CPU and other component receive? My goal here is to achieve max performance from the knew CPU 2.5, as the other was a 1.6.
Or is it something ( coded ) written in the board to limit or restrict other Bios upgrades. After all, both the ( same )board's, Bios are Dell.
