CPU upgrade for Satellite 5205-S505

Depends on the socket type.. Socket 423 and 478 do not support core duo or quad core processor types. However, if you have LGA 775 (aka socket T) your motherboard will support the following:
Intel Pentium 4 (2.60 - 3.80 GHz)
Intel Celeron D (2.53 - 3.60 GHz )
Intel Pentium 4 Extreme Edition (3.20 - 3.73 GHz)
Intel Pentium D (2.66 - 3.60 GHz)
Pentium Extreme Edition (3.20 - 3.73 GHz)
Pentium Dual-Core (1.40 - 3.33 GHz)
Intel Core 2 Duo (1.60 - 3.33 GHz)
Intel Core 2 Extreme (2.66 - 3.20 GHz)
Intel Core 2 Quad (2.33 - 3.00 GHz)
Intel Xeon (1.86-3.40 GHz)
Intel Celeron (1.60 - 2.40 GHz)

Yes, it will work just fine, as you can see for yourself - on the mb's link is the third processor from the second group (Prescott).

You are basically limited to what was optional on the model. So you can only upgrade to one of the following cpus:

Intel Pentium M 745 (1.8-GHz) with 400-MHz front
side bus (FSB)
Intel Pentium M 735 (1.7-GHz) with 400-MHz FSB
Intel Pentium M 725 (1.6-GHz) with 400-MHz FSB
Intel Pentium M 710 TJ85 (1.4-GHz) with 400-MHz FSB;
operates at a lower temperature than other processors
Intel Celeron M 340 (1.5-GHz) with 400-MHz FSB
Intel Celeron M 330 (1.4-GHz) with 400-MHz FSB

And you are limted to 2gb of ram max on this model.

motherboard does not support this UPGRADE of processor, Regards

Be warned: If the upgrade is possible at all for your laptop, it can be a time-consuming operation that involves disassembling virtually your entire notebook, so don't enter into this process unless you are willing to accept the risk of doing serious harm to your machine.
On some newer, high-end notebooks, the graphics card can be accessed simply by opening a panel on the bottom of the computer. But for most older machines, disassembly will take more steps.
The first thing you need to know is that your laptop can probably support only a handful of very specific graphics cards, if the card can be upgraded at all. Your best source for an upgrade card will likely be the manufacturer that made your portable.
Be sure to consult your laptop's service manual (which can usually be downloaded from the manufacturer's support page) before attempting to open up your machine. Also, make sure you guard your hardware against possible electrostatic discharge by wearing an antistatic wrist strap whenever you handle any internal components.


If you really want to upgrade your graphic card, let me know and post the additonal question in the thread. I will try to answer your questions.

Hi ryonsdad,

I checked out the Latitude D610 laptop, and you'll be glad to know that you have the following processor upgrade options:

1.) Pentium M 780 Processor - 2.26 GHz, 2MB, 780, Pentium-M Dothan, 533FSB (fastest upgrade)
2.) Pentium M 770 Processor - 2.13 GHz, 2MB, 770, Pentium-M Dothan, 533FSB
3.) Pentium M 760 Processor - 2.0 GHz, 2MB, 760, Pentium-M Dothan, 533FSB
4.) Pentium M 750 Processor - 1.86 GHz, 2MB, 750, Pentium-M Dothan, 533FSB
5.) Pentium M 740 Processor - 1.73 GHz, 2MB, 740, Pentium-M Dothan, 533FSB (slowest upgrade)

You can buy these processors from Dell Spareparts or otherwise from a 3rd party store.

Hope this helps!

Peace! :)

you could only upgrade the processor and RAM in this condition i.e.

you can only change your an upgraded p-III processor like 1.0 GHz, 1.1 GHz or 1.3GHz and
upgrade the RAM by changing to 256 in each slot.

that is all what u can do with ur pc

I told you my opinion, If I was in your shoes I won't upgrade the CPU.Professionals do not do works against Factory specifications, and I fixcomputers for living.
Acer says Pentium dual is not supported on Acer 4315, I can only tell you not to do such an upgrade.
Itwould be the same as if you ask me if you can mount a Jaguar engine ona Mini, yes, for sure there is the way to mount it, but the car won'twork as it is supposed to, and risk to blow at first corner.
If you really want to replace your CPU consider the following.
Acersays pentium 2 dual core is not supported on 4315, if you do ityourself you risk to damage the computer. Do not do the CPU upgrade ifthis is your only laptop, or if you care of this laptop, chance ofdamaging laptop are high. This kind of upgrades are done more as anexperiment.
I know Core 2 Duo T5300 1.73 Ghz had been installedsuccessfully on Aspire 4315, Acer says not to install any core duo, Iknow for sure Pentium duo T5200 1.6 Ghz works on Aspire 4315 with noneed for replacing cooling system.
Both chipset are difficult to find, best place to find them is Ebay.

Check this link for an extensive report on this matter:

check also: Is it worth upgrading the CPU on Acer Laptops?

1. Check user documentation for supported CPUs for your system.
2. If 2.0GHz CPU is supported on your system, you don't need any additional software.
3. I would upgrade the BIOS firmware first. It might have an additional CPU support.
4. Read information from you old CPU. Exemple: 1.4GHz/256/400. 1.4GHz is a speed of your CPU. 256 is a 256k cache, and 400 is 400MHz BUS speed. In general you can boost speed to 2.0GHz or more and cache to 512k, just keep your BUS speed to 400
5. Post your system model or your motherboard model. That information would help in determining the maximum speed of the CPU for your system.

Good lick!

you should upgrade computers, because a pentium 2 and 3 wont do ****.
