Inspiron 1150 CPU Upgrade
I have so far upgraded the RAM to 2GB on this laptop, and upgraded the CPU once in the past to a Pentium 2.66GHz CPU, and so far it was good. I recently had I purchase a new battery cause my old one gave the flashing amber light of death.
However, I want to get the CPU even faster than before, and max it out just like I did the RAM. What is the fastest CPU it can handle? I tried an SL7NA Pentium 4 3.06GHz CPU cause it had the same 533MHz BUS as my current P4, but got a microcode error, which I felt it would since that is a Prescott core and not a Northwood.
Any information is welcome, thanks.

As far as heating is concerned, I have modified the cooling system to something more eficient, custom made.
I will try to find another P4 mobile at work that is a northwood.
I assume it has to be 533MHz tops. I don't think the board can handle anything 800MHz bus.

Any of the Northwood P4 mobiles will work - that said, the system had trouble coping with the standard CPU. Upgrading it to a faster one could result in instability or hardware failure due to overheating.
The system does not suppot any Prescott-core mobiles.

Correct on the 533 bus - there are no 800 MHz Northwoods. I believe the 1150 is hyperthreading-incapable as well.

Actually there are some 800MHz northwoods, just not mobile. SL6WK being one of them. I build my father a PC a while ago with that CPU.
And correct, the 1150 doesn't have HT. I've checked the BIOS, it's just not in it. (In a binary dump of the firmware, not CMOS setup utility).

I just ran across an odd CPU. Celeron D SL7Q9.
It's a Prescot core, but worked on my 1150. It of course gave the microcode error, but upon booting anyway, Windows booted right up, saw it as a Celeron D, and even gave the SSE3 instruction set. I didn't check to see if EM64T was working or if the CPU even had it. I'd doubt that one, but it was working. Being my Vista installation was installed on a single core CPU, the propper ACPI HAL wasn't loaded. I might do a reinstall and see if the dual cores actually fire up. Once again I doubt it, but this is interesting, minus the microcode error.
