Presario CQ57-339WM | Processor Upgrade?

The processor is not soldered. It can be swapped out; just wondering which mine are capable of using.

Really? I've worked on several laptops over the years and have ran into far more exchangeable cpu boards than the embedded counterparts found in most new HP laptops (specifically the 15 series).

Unfortunately for me, however, it appears as if my motherboard is limited to the processor it has in it; it's the highest available processor made for the specific board in my system (still not bad to be a dual core 1.5GHz 1333MHz FSB 2MB L3 Cache) but I feel this still severely hampers the potential of the memory speed and allowance.

Not wanting you to think that I overlooked your comment regarding the other thread, I looked at it and I can tell you with 100-percent certainty that most 2004-2009 Dell, Compaq, and HP laptops were made with socket CPUs that can and have been upgraded. I can even give you a couple of personal examples.

I upgraded a Compaq Presario CQ62-219WM that came stock with an Intel Celeron 900 (2.2ghz) CPU to an Intel T6600 Core 2 duo (2.2ghz, 2MB, 800FSB, 1MB L2 Cache) and it made significant changes to performance and actual CPU load. Ran CPUID and Everest Home and both detected the upgraded processor as working perfectly; as did the actual Intel Processor Diagnostic Tool. It ultimately comes down to chipset compatibility and the maximum specifications of said chipsets along with the socket type that the laptop's board uses. In this instance, Any Socket P Intel processor with a maximum of 800MHz FSB will support the board's GL40 chipset.

Another personal example would be the Dell Inspiron 1525; again, having a Socket P Intel GM965 chipset, could handle essentially any Socket P processor running with a maximum of 800MHz FSB. In my case, I upgraded from a Celeron 550 2.0GHz, 533MHz FSB, and 1MB of L2 Cache) to an Intel Core 2 Duo T9300 (2.5GHz, 800MHz FSB, and 6MB of L2 Cache). Once again, the system works flawlessly with its 6GB of ram (Dell says the limit is 4GB, but you can get complete use of 6 with the latest bios update for the system; so long as it's 64-bit, but that's a WHOLE other story lol).

The common attributes of these two different systems by two different brands are the fact that they both use Intel-based Socket P boards with Intel chipsets and the fact that both version's respective chipsets allow for flexibility in specific attributes of the CPU so long as the threshold of these specific attributes aren't overstepped. Those specific attributes of this particular Socket (Socket P) and the respective Intel chipsets are the 800MHz FSB and the 35w limit.

With that out of the way though, sadly, my system's (CQ57-339WM) motherboard is built specifically for the Celeron version of Intel's processors, and mine came with the strongest one available right out of the box. So while it's disappointing that while I solved my own question, it didn't bear any good news, I can smile knowing I helped enlighten another techy about the capabilities of laptop CPUs and chipset scalability. =)
