Laptop CPU upgrade/interchange...Will any socket P CPU interchange with a T2390

[Wangstang]

I have an Acer 5620-4801 laptop that has 3 gigs of ram and an Intel Pentium Dual Core T2390 CPU. The T2390 is an OEM Socket P chip rated for 1.86GHz /533 FSB/1MB L2.

Edit to add:
The T2390 is a "Merom-2M" chip (65 nm) which runs in 64 bit.

Can I drop any Socket P in it's place and fire it right up?

Initially I was looking at the T8300 as it looks like it's a drop in interchange. BUT, there are other Socket P chips out that would be nice to go with as well, such as the E8435 or the P8600 and all of the other socket P's out there.

Obviously I do not want to toss money into parts that will not work so a little help with this would be appreciated.

Thanks
Wes

This would be the fastest cpu within your current tdp and bus speed.

That's odd, it has 1mb more L2 cache but everything else is lower than my existing CPU. I've read online that the the T8300 is a drop in. It runs significantly faster in every aspect.

I don't mean to be rude by asking as I'm clearly not sure of the answer myself, but how sure are you that the chip you linked is the most I could install?

From what I've read over so far on the net, this architecture allows for Bus speed increases by simply swaping the chip and not the motherboard so long as you stay with in the same chip socket design. Obviously the speed of the RAM needs to be upgraded to keep up with the processor's bus speed or it will choke the system down. Did I total misunderstand that?

Thanks,
Wes

If you drop in a cpu that has a higher fsb it won't make it run at that. The motherboard has to support it from what I believe. From what I am reading your chipset can support up to 800MHz fsb so that would bump the cpu up to the T7800.

From the acer website it does say the T7700 is compatible but the T7800 will work as well.

Yeah, I fired up CPU-Z and got the motherboard model. Intel GM965

http://www.intel.com/products/...965/GM965-overview.htm

It supports 533 and 800mhz processors.

The T8300 is 800mhz:

You can find socket types for processors here:
http://en.wikipedia.org/wiki/L...Core_2_microprocessors

And here:
http://en.wikipedia.org/wiki/L...l-Core_microprocessors

It looks like the Intel Core 2 Duo line up is supported.

Off to do more research, I'd love to hear more input.

Thanks

The X7900 is supported. I was using intels http://processorfinder.intel.com/Default.aspx.

I don't think E4600 would be supported the sockets are not the same.

I would see if they have a bios update first though. Just because a cpu is supported doesn't mean the bios will work with it. If there is none only way to find out is try it out.

Yeah, I forgot to cross reference the socket type.

Looks like the T9300 would interchange:

That might be a little trickier Wes because the T9300 is a 45nm process while the others we've talked about are a 65nm process. That might require a bios update if it is even supported.
