I have an elitegroup 945PL-A motherboard. When I installed an intel single core processor it works just fine. When I tried a dual core processor the computer would not boot up. Help me. [email protected]

Page 16 of the Technical Product Specification guide;

3.1.1 Processor Support
"The Intel Server Board SE7505VB2 supports one or two processors in the 604-pin FCPGA package."

-> Socket 604,

http://en.wikipedia.org/wiki/Socket_604

-> Intel XEON processors ONLY

"When two processors are installed, all Processors MUST be of identical revision, core voltage, and bus/core speed."

-> Means you really should use two IDENTICAL processors.

"When only one Processor is installed, it should be in the socket labeled CPU1, and the other socket must be empty."

-> Self-explanatory.
That's the processor socket furthest away from the black AGP graphics expansion slot, and closest to the outside edge of the motherboard.
(Page 104, and 105)

ONLY supports Intel Xeon processors with a 400MHz, or 533MHz FSB.

Dual-Core Xeon's start at 667MHz, and wouldn't work anyway; due to different Core architecture, and Instruction Sets.

667MHz, 800MHz, 1066MHz, and 1333MHz, for dual core Xeon's,

(Scroll down just a touch, to get the Wikipedia 'banner' out of the way, or click on it's X)

Scroll down the page, look at the charts. Starts with 800MHz FSB for Dual Core, then goes 667MHz, 800MHz, 1066MHz, and 1333MHz, Front Side Bus.

Use Dual Core processors?

No.

Two Single-Core processors.

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)

No, the Intel (Ausberg) 915G motherboard will not support dual core processors.

The Intel (Ausberg) 915G motherboard uses an Intel 915G motherboard chipset,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4.2FPentium_D.2FPentium_EE_Chipsets

Supports only Single Core processors.

It isn't until the Intel 945G motherboard chipset, that Dual Core processors are supported.

[NOTE*
The Intel Celeron D is a Single Core processor.
The Intel Pentium D is a Dual Core processor,

Intel Celeron D,

http://en.wikipedia.org/wiki/Celeron_D#Celeron_D

"The Intel Celeron D processor works with the Intel 845 and 865 chipset families. The D suffix actually has no official designation, and does not indicate that these models are dual-core. It is used simply to distinguish this line of Celeron from the previous, lower performing Northwood and Willamette series, and also from the mobile series, the Celeron M (which also uses 3xx model numbers). Unlike the Pentium D, the Celeron D is not a dual core processor."


Intel Pentium D,

Don't 'shoot the messenger'. I just state the facts.

Yes this motherboard is compatible with the Intel Core 2 Duo E6550 processor since the maximum processor support of this motherboard is core 2 duo LGA775 Socket so everything should be fine between these motherboard and processor.

Yes it can support it. It supports all models of intel dual core processors.

Yes you can.
Your motherboard is LGA775 socket and supports the folowing processors:
Core2 Duo / Pentium Dual Core (yours) / Pentium D / Pentium 4 / Celeron 4xx series/ Celeron D.

You are worrying about nothing.

Intel Pentium Dual Core and Intel Celeron Dual Core are both Intel Core Dual processors.

The performance rate is mesured compared to a single core processor so your 2.2GHz dual core will do the same amount of work as a 4.95GHz single core.

please give me a software copy of motherboard P4 M 800 -M7 A ver 7.1

LGA775 socket for latest Intel® Core™ 2 Duo / Pentium® Dual Core/ Pentium® D / Pentium® 4 / Celeron 4xx series/ Celeron® D processor FSB 1066/800/533 MHz

The above information was taken from their website.

Your motherboard MSI 945pl-neo support Supports four unbuffered DIMM of 1.8 Volt DDRII SDRAM.( Supports up to 2GB memory size.
• Supports dual channel DDR2 memory architecture.
• Supports DDR2 533/400 memory interface.)

and Supports Socket 775 for Intel® P4 5XX, 6XX, P4EE, Pentium D 8XX and Celeron D processors.• Intel® 945PL/ ICH7 Chipset
