dv6000t cpu upgrades

I have an hp dv6000t with celeron m 420. What cpus other than celeron-m can i upgrade to?

I was thinking about the new cheap cpus like the 64bit celeron-m (5xx series), or the pentium dual-core mobile.

Also what's different between the celeron motherboard and the core motherboards? Is it just the RTC battery and bios or is it more involved than that?

 

You should be able to upgrade to any of the Celeron M 400/500 series, Core Duo, or previous-gen Core 2 Duo processors (not the new Santa Rosa ones, they use a different socket).

First we must figure out what sort of chipset you have to ensure compabibility. Download CPU-Z and find out:

Sometimes the Celeron computers are shipped with a cut-down chipset (you might have the 940GML, which only works with Celerons).

You do realize that upgrading the CPU is not easy and it voids your warranty. I wouldn't do an upgrade unless you feel it is necessary. What are the full specifications of your computer?

 

Well, cpu-z 1.40.5 reports it as 'i945PM/GM/GT/i940GML Rev 03'. Mainboard is a Quanta 30BB - 66.21(not sure what these last number are).

It's based on the basic hp config:
-what is supposed to be a 945gm chipset with gma950 graphics
-1.6ghz celeron-m 420 (yonah core, 65nm)
-2x 512mb ram @ 533 fsb (the SPD on cpuz shows up to 333/667 fsb)
-80gb 5400rpm hdd
-2 usb ports
-non intel wireless
-no bluetooth, camera, expanded multimedia buttons

I googled and found a 943GM for dv6000t, which is a board for celerons. In the description it states that the RTC battery limits the cpu to celerons. Now i wonder if i replacing the RTC battery will allow me to use the core cpus, i mean fully working speedstep. Like you mentioned it's not that i need more cpu power, but i want one that can throttle down, so the battery last longer per charge.

By the older Core 2 Duo, you mean the ones that run on 667mhz fsb right?

One more question, does this board support enhanced halt state C1E?

 

well if thats true then it could limit u from using speedstep but it cud also be a physical limtation of the motherboard or the BIOS it uses, so it may not actually support those features.

 

If the board/chipset only accepts Celerons then I'm afraid you can't get a CPU that will throttle down. Have you considered investing in a 12-cell battery?
