my laptop gaming performance sucks, because I have an i3 with only 2 cores clocked on 2.2GHz (i3-2328M). So recently I found an i5 with also dual core but clocked on 2.5GHz with turbo up to 3.1GHz (i5-3210M). I have checked and compared parameters of those two, TDP = same, socket = same, but the bridges are different. After some search I found few answears, that say the ivy cpu can be put on a sandy motherboard laptop, but I need to be sure about my bios support. The problem is that my laptop (Toshiba Satellite C850 19Q) doesn't have it's motherboard name published so I can't know the support of motherboard. So if there is someone who knows more, will the mentioned i5 work with my H2O BIOS (Latest version from Toshiba - 6.80). Anyhow... Please, tell me, since the CPU is now very cheap but not for long and shipping is for me very expensive, so I don't want to invest a lot of money to discover that it doesn't work. Please do not move my question off, I really need help :(
Your motherboard probably uses the i3-2328M CPU (Intel spec sheet), a Ball Grid Array CPU. Soldering of BGA devices requires precise control and is usually done by automated processes. Humans have a -very- difficult time with this kind of work, and it is not recommended.
Also, many of what are sold as i5-3210M processors are also Ball Grid Array CPUs.
