Best motherboard which supports core 2 duo processor

you posted a statement of fact not a question.
it will support
not
will it support(a real question)

well NO
and NO PC stated, only mobo.(lost the PC ?)
nor that this PC was mobo bought in India?
YOUR mobo is core2, not core(tm) processor
they are not even the same class nor socket
no
here is the list of core i3 (all are LGA
your mobo is core2. (older )
all are over 1000 pins, LGA1156 (gen 0)

you can not stuff 10 pounds(or kg) of mud in 1 pound sack.
no can do.

The socket type of ACER G45T/G43T - AM3 V1.1 motherboard is LGA 775. Here are the compatible processors you can use for this motherboard :
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)

Hi,
This motherboard model will not support Core 2 Duo E4600.
It will support only.

1.Intel Pentium D Processor.
2.Intel Pentium 4 Processor.
3.Intel Celeron D Processor.

Thanks for using FixYa.

Hi,
Your motherboard is compatible with the e5800 processor.

It has Intel® Socket 775 and it will support processor listed below
1. Core™2 Quad.
2. Core™2 Duo.
3. Pentium® dual-core.
4. Celeron® dual-core .
5. Celeron® Processors

Thanks for using FixYa.

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, perfectly fine. read this:

HI,

The only Thing To Do, is view both Motherboards, user Manuals.
To see The boards CPU Support List.
It could be to do with, certain Motherboards Supporting, certain CPUs.
I.e a 533mhz cpu, would not run on a Motherboard that supports 400mhz. The Systems Bios, May cause Other Problems.
If your getting a Black Screen, is it a possible Graphics/Ram Problem, Rather Than The CPU ??

You can also use any other intel 775 socket processor as well. The dual cores are at the top of the list for performance that are compatible with that board, but if you're looking for a cheaper solution, I have that board with a 3GHz pentium 4 and it runs great. Here's a list of all the processors you can use.
Intel Pentium 4 (2.66 - 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)
Intel Pentium Extreme Edition
(3.20 - 3.73 GHz)
Pentium Dual-Core (1.40 - 2.80 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 'Core' Celeron (1.60 - 2.40 GHz)

The pentium d 915 is a dual core processor, albeit a bad one. You should check google for info on your motherboard to see if it supports Core 2 duo's/ Core 2 quads. I have an E6600 overclocked to 3.0ghz and it still plays games perfectly paired with my 8800gt 512mb and 4gb's ram. I definately recommend upgrading to a core 2 duo. I used to have a pentium d 915 and it was bad for gaming and the e6600 blows it out of the water. You most likely wont find the e6600 anywhere as it is nearly 3 years old. Look at sites such as toms hardware to find a good core 2 duo.

Good luck- an t-adh leat!

Hi 
Pentuim D is a processor that has 2 x cpu in one and a core 2 duo has 2 cpu's plus 1 smart core bigger cache 
you can only upgrade to a E2140 or E2180 processor on that motherboard 
OR replace the board with a newer type

If you want to work the actual speed for the processor of a dual core take the speed for example dual core 1.8 x 2.1 =3.78 GHz 
Core 2 Duo  1.8 x 2.4 = 4.32 GHz
