Laptop hardware component & upgrades forum: Acer Aspire 5515 Processor Upgrade???

It MAY work IF you never have to leave Windows AND use a throttling application, such as RMClock at the same time. Remember that you have to finish loading Windows to apply throttling/undervolting etc. The factory BIOS doesn't provide for this kind of thing, since it's set to work with the stock 2650e CPU. Now, I'm running a dual-core BE-2400 in my 5515, and everything was fine, until I had to restore my C:\ partition from a user backup. That was a real pain in the bottom, let me tell you. The laptop kept shutting down from thermal shutdown (CPU overheated). I finally got it done by removing the CPU cover on the bottom of the laptop and elevating it by about 1/2" in the back (setting it on 2 CD jewel cases), AND switching to the backup I saved on my hard drive (as opposed to the DVD disk set I made), thank goodness I didn't delete it. All that just short of re-installing the stock 2650e CPU, which I dearly hoped I didn't have to resort to. So, anyway: I am using RMClock to undervolt my CPU in Windows, and this works very well keeping the temps in check. Heck, with Windows loaded, I can even run the BE-2400 without RMClock, and by running I mean put some stress on the CPU. It will throttle back before it gets too hot. Point is, this ACER Aspire 5515 laptop was NOT designed with a 45W TDP dual-core processor in mind, let alone a quad-core CPU. Cooling is just about adequate for the stock 2650e.
