But Jack, he said in the first video, the i5-580M CPU successfully installs and works on his 5742ZG. But you're saying the 5742ZG only supports the Pentiums. Unless I'm reading it wrong. I have a question, popak, do you know which chipset is in your 5742ZG? Because if it's the Mobile Intel HM55 Express chipset, then that would explain why the i5-580M CPU successfully installs and works. If you take a look at this list of supported processors for the Intel HM55 Express chipset (Socket G1), you'll see the fastest supported processors for the Celeron Dual-Core, Pentium Dual-Core, i3, i5, i7, and Core i7 Mobile Extreme CPUs.http://www.cpu-upgrade.com/mb-Intel_(chipsets)/HM55_Express.htmlCopy and paste the whole link.
I also updated and it works
The one in the picture is an i7-640M...

In future look at this site "CPU-UPGRADE". Get
your OEM CPU's specs and look it up on that site, it will give you a full list
of your CPU's other spec and the possibility of an upgrade (as from a certain
period laptop and the current laptops CPU’s are NOT upgradable) look here: https://www.cpu-upgrade.com/CPUs/index.html
Btw, I've done many upgrades on the Aspire 57xx, V3 and V5’s
and probably all the socket CPU’s that can be upgraded on laptops and they can all be upgraded pretty well from either their lowest spec i3s to the mid spec i5's
or the top range i7's type Intel CPU's but you need to also upgrade to a
2.5" SSD and faster RAM to make them fairly useful with the current Win-10
Usually not. Higher speed RAM will only run at the maximum speed allowed by the mainboard 1033MHz. Some earlier mainboards were even lower speed. Jack E/NJ
