eMachines EL1333G-01w CPU Upgrade

Hi, I noticed there was a post by member visschan titled
Solved: eMachines EL1333G-01w CPU Upgrade HELP please!
Basically member was typing to find an upgrade CPU for EL1333G-01w

I also have the same machine and was enthused that there was an upgrade path. I did the same research on the CPUs and ended up purchasing a Athlon Neo X2 6650e which is a 35W dual core CPU. I was after the lowest power CPU I could get since the machine is on most of the day.

Well I did the installation and powered on. The CPU runs but hangs as it tries to boot Windows. I read that the BIOS might need upgrading before changing a CPU core. Anyone know if its a BIOS issue or is the 6650e different to say 5050e or 4850e?

Any help Appreciated.

 

Some more information on this issue:

The BIOS is Phoenix-Award version P01-A4. It has a release date of 12/17/2009. I checked around and as far as I could make out that's the latest for this machine. The BIOS does run. everything looks normal at that stage.

I make a bootdisk with this ISO "X17-59465.iso" and tried to boot from that. it loads files, then comes up with the "Starting Windows" screen but that's as far as it gets.....it just hangs on that screen

If I pop the 2850e CPU that was originally in it back in it behaves normally. Evidence is that the 6650e is running ie its not DOA.

the search continues
