Inspiron 9300, M 740, BIOS A05, Chipset i915PM/GM Rev 03
I bought a used M 780 but didn't function. So I contacted Dell they told me that with my chipset only a maximum of 2.1 Ghz CPU will work. Dell didn't answer to my question if i can do something to make it run. I cannot really say if the CPU is broken, I trusted the vendor. Before I send the CPU back I wanted to be sure if Dell isn't wrong with their answer because some of you run the 9300 with this processor.
p.s. FWIW, I scored my 780 as a "working pull" via eBay. It didn't even come out of a Dell machine and it worked like a charm and fired up right away and was recognized as the 780 in BIOS and otherwise.
I'm now convinced that a M 780 works in an Inspiron 9300, I probably bought a broken CPU. It is almost impossible to know it before you have it in your hand. Just wanted to make shure that it isn't my fault by missing some settings. I unfortuntely have no other laptop to test the CPU. The pins look good.
Sorry for any inconvenience I thought its from interest what information I got from Dell.
The Pentium M 780 should most certainly work in the Inspiron 9300. I upgraded from the M 760 to the M 780 and noticed significant improvements in performance. The Windows Experience Index subscore for the processor rose from 3.7 to 4.0 with the M 780. Overall latency also was dramatically reduced. Just be careful swapping the CPU and be sure to clean the old thermal compound off of the heatsink and apply fresh thermal compound. I used Arctic Silver when I swapped my CPU.
