Dell's BIOS supports the new CPU? And if the CPU is in a socket?
Either will deny such an upgrade. Also, ask Dell since they'll know.
I presently own a Dell Precision M4300 Laptop based on an an Intel Core 2 Duo T7300 CPU with 4MB L2 cache. They are now selling these systems with the T9300 (and others) Penryn 45nm processors. I noticed that there were a flurry of BIOS updates for my system right around this time and I always have upgraded so I am now on version A09.
I was wondering if there was really anything different about these new models of the M4300 or if my laptop would accept the same CPUs being sold in the new laptops. I bought this unit a few months old at a dramatic discount and seem to remember it being shipped to the original owner in Oct 2007. I know that sometimes there will be multiple revisions of the same motherboard model and want to make sure my computer will support the Penryn update first.
Some forums state that the Santa Rosa is restricted to 65nm and cannot be upgraded. Others state that you should just be able to drop in provided you have a recent BIOS revision.
Since this unit already has 4GB of RAM and a 200GB 7200 RPM hard drive, this will be my only major planned upgrade prior to replacing the unit in a few years once Nehelem or another such unit becomes commonplace. I plan on the T9300 CPU (2.5GHZ) unless I hold off for a few months as there is a significant price increase for the T9500 (2.6GHZ model).
If a motherboard replacement is in order, I might get another 65nm CPU in a few months once the prices drop.
So, my main question is... Is there any reason I should NOT proceed with this CPU upgrade when I feel the time/price is right? The thermal output is lower than my existing chip and cooling shouldn't be a problem.
