I am getting new CPU for Christmas...I'm confused!


Nov 17, 2009
Alright so lets get right to it then, shall we?

I'm going to be getting this CPU for Christmas.

I current have an AMD 64 X2 Dual Core processor 4400+

if it helps, heres a bunch of system information that includes what motherboard i have.

2.30 gigahertz AMD Athlon 64 X2 Dual Core
256 kilobyte primary memory cache
1024 kilobyte secondary memory cache
64-bit ready
Multi-core (2 total)
Not hyper-threaded

System Model -
Acer Aspire E380 R01-B1
System Serial Number: PTS550X029706080152703
Enclosure Type: Desktop

Main Circuit Board-
Board: Acer EM61SM/EM61PM
Bus Clock: 201 megahertz
BIOS: Phoenix Technologies, LTD R01-B1 12/29/2006

My current processor is socket type AM2: http://www.amdcompare.com/us-en/desktop/details.aspx?opn=ADO4400IAA5DD

The new one is type AM3: http://wheretobuy.amd.com/us-en/prodinfo/1232148.html?price_tab

According to this article, if you have an AM2 motherboard (which I must...since im using an AM2 processor) you can use an AM3 processor since it is backwards compatible. http://arstechnica.com/hardware/news/2009/01/quick-reminder-am3-chips-compatible-with-am2am2-boards.ars

Ok so first of all, can someone confirm that the new processor IS FOR SURE compatible with my current motherboard?

Second of all, im pretty sure that I have to do a "BIOS Flash". I have found the newest bios (I think) for my computer here: http://gd.panam.acer.com/home/

Go to desktop>aspire>e380. There is a tab for BIOS. Is this the newest one? Am I supposed to download that and install it somehow? How do I install it?
Most importantly, lets say I just download that in advance, lets say today, will I be able to use my computer WITHOUT the new processor installed? By flashing the BIOS, does that make your computer un-usable until you get a new processor?

Ok, and once I flash it, am I good to install the new processor? I need to use that thermal compound stuff right?

Is it as easy as just putting the new processor in, turning on your computer, and it will work?

sorry that was really long but thank you!

*by the way, with that acer website, it asked me to select my region. There was no United states option, the closest thign to united states was "Pan America" so that was what i selected. not sure if that matters.



Yes it's an AM2 board.

It's not AM2+ or AM3 Processor compatible.

Only a few AM2 boards work with AM2+ processors (much less AM3).



That was a badly written article. It is not as black and white.

With AMD cpus's some boads can only handle AMD processors up to something like 95W anything above that won't work properly.

Also the article does not take a bios update into consideration (something which your motherboard has not had since 2007).

In the end, far too many AM2 boards remain incompatible with AM2+/AM3 CPUs (yours being one of them).


Although AM3 processors are physically compatible with AM2 motherboards, most AM2 motherboards don't offer BIOS support for AM2+ or AM3 processors. There are also a number of AM2+ motherboards, that due to lack of a BIOS update, cannot use AM3 processors. AMD made the processors socket compatible, but it is still up to the motherboard manufacturer to release a new BIOS for software compatibility.

hahaha sorry guys im an idiot... I have an athlon X2 not II.

Anyways I decided to get a new ASUS motherboard for a little over one hundo as well as this graphics card.

Im actually glad. I dont want to keep my piece of crap motherboard. I already got the new graphics card as well so i might as well just go upgrade the three main components.

Is anyone still in this topic? @Topic Starter, What kind of Asus motherboard did you get? I also have a acer e380 but i don't know which mobo would fit. Please reply. Thanks
