Go to SolutionUpgrade E6500 CPU to QX9300?
I have an E6500 with a T9400 CPU (Core 2 Duo, 2.53 GHz, 1066MHz FSB).
I would like to upgrade it to a CPU that is either a quad core or dual core with hyper-threading. The only CPU I can see that is even a possibility is the QX9300 (Core 2 Extreme, 2.53 GHz, 1066MHz FSB).
The CPU I have is listed by Intel as supporting BGA479 and PGA478 sockets. But, I don't know which my motherboard has.
The QX9300 is only listed to support PGA478 sockets.
Reading on various forums, it seems like even if I am able to upgrade, I might be opening myself up to heat problems.
OTOH, I also read that the the E6500 is identical to the M4400 except for the lid. And the M4400 is available with the QX9300 CPU.
So, can anybody tell me if I can replace my CPU with the QX9300? If so, would it require anything more than just buying the new CPU?
Thanks for any help!

Thanks for the reply!
So, you're saying the E6500 has a PGA478 socket, which means it's a "pin-grid". And, therefore, the QX9300 will fit. That's good news!
And are you saying that you know that the M4400 has a larger heatsink? Or are you just suggesting that I check on that?
Thanks again!
Gotcha. I have now looked at the Dell Service Manuals for both the M4400 and E6500. I looked at the instructions and pictures for replacing the CPU heatsink (cooling assembly) and the CPU and they look identical.
Barring somebody telling me they have successfully performed the same upgrade that I'm interested in, I'm not sure what else I can do other than just get a QX9300 and put it in.
Thanks again for the info.
I installed it last night and it doesn't work.
When I power on my laptop, it turns on, but the screen never displays anything. It stays on for about 5 - 10 seconds, and then turns itself off. If I hit F2 (or any other key) while it's on, the keyboard backlight comes on, but nothing else happens and then it just powers back off.
I put the original CPU back in and it booted back up and runs just fine.
I'm wondering if I need to flash it with an M4400 BIOS.
Any ideas? Anyone? Anyone? Bueller?
I know its like 5 years later and i want to attempt the same mod on an E6500, ( I JUST LOVE THE WAY IT LOOKS- clean edges , styling and design , and not a shiny rounded (ugh!) soapbox like newer ones!)
I think your mod could fail if it had integrated graphics, most early quad core mobile cpu's need a discrete video card, did your laptop 5 years ago have an intel or nvidia mobo ? im guessing if you had a discrete video card like nvidia nvs 160m, it would most likely work. if you did in fact have integrated graphics, then it is the most likely explanation for your display failure.

jb,
just wondering if you ever considered the Core Duo T9900?: cpu.userbenchmark.com/.../IntelR-CoreTM2-Duo-CPU-----T9900----306GHz
If so, why did you decide against it?

I did upgrade for my E6500 to QX9300 (from T9400) and it works well, but I cant activate 4 cores.. There is still 2 cores acrive for me. I did benchmark tests and results are the same as for T9400, as frequency is the same. Point of upgrade was the advantage of quad cores, that is no available for me... I even formatted my HDD and reinstalled windows from scratch and this didn't help. I am attending to replace thic CPU with X9100, as it it due core processor and has highest freqency in these socket P family processors.
