Cpu suport

Going with problem heading stating ->

IBM 73P0595 motherboard > CPU Support > and previous problem statement ->
"I have updated my processor from INTEL Pentium d 820,2800mzh 1500mzh to INTEL Pentium d 945,3400mzh....."

Let's take a look at the IBM 73P0595 motherboard specifications, first;

A) Socket 478 processor socket

B) Intel 865G motherboard chipset,

The Intel 865G motherboard chipset DOES NOT support dual core processors.
Does NOT support an Intel Pentium D; 820 OR 945

Those two processors also use the LGA 775 processor socket.
(Socket T, )

What did you base your CPU support on?
Was it the fact that the Intel 865G motherboard chipset, will support Intel Celeron D?

The Intel Celeron D is NOT a dual core processor,

"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......"

Not the IBM 73P0595 motherboard we're talking about?


Let's just base it on the statement that you tried to upgrade, from an Intel Pentium D820 to an Intel Pentium D945,

What motherboard are you using?
Motherboard in a HP Compaq DC7600 Desktop PC?

Scroll down to the bold subheading -> Processor and Speed

Intel Pentium D820 at 2800MegaHertz (2.8GigaHertz),
with 800MegaHertz Front Side Bus, is supported.
(800MHz FSB)

Probably came with your computer, huh?

Intel Pentium D945 at 3400MHz (3.4GHz), with 800MHz FSB is supported also.

This can be seen by the specifications of the motherboard chipset, also. The Intel 945G motherboard chipset,

Scroll down to 945G in the left column. (Last one listed in chart)

Apparently you just needed the 786D family Processor Microcode Update, or did that not work out?

Awaiting reply,

(How did I come up with the HP Compaq DC7600, anyway?
Did you add it in a Comment, and it has been removed, or what?

!O_O! )

I like that. Kinda' rhymes. "Fan OK but no Display"

Problem is your Processor isn't turned on.

You have a bad Power Supply.
> Weak voltage power rail.

You probably have a 200 to 300 Watt power supply. (SMPS)

1) ALL of the LED lights together use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts.

3) A typical Processor can use 51 to 125 watts. Depends on what Processor it is.

The Intel D845GVSR motherboard uses a Socket 478 processor socket.
Supports Intel Celeron, Intel Pentium 4, and Intel Celeron D, that utilize a Socket 478 processor socket, and have a maximum FSB of 533MHz.

Utilizes the Intel 845GV motherboard chipset.
[ Intel 82845GV Northbridge chip, and Intel ICH4 Southbridge chip ]

89 Watts is the maximum wattage, that can be used by a Processor for the Intel D845GVSR motherboard.

Power Supply has enough power to light LED lights, and spins fans, but not enough to turn the Processor on.
No Processor operating, No computer.
No computer, No video signal to the monitor.
(No Signal)

Do you have access to a KNOWN to be good, compatible Power Supply, for a test unit?

I need good processor what is better intel pentium or amd athlon?

Hi nestorjnk, if your question is in referance to the Intel D915GAG motherboard you can only use an Intel CPU. The supported CPU list for this motherboard can be found on the link below;
This is the highest CPU that can run on the D905GAG motherboard; (Click the link).

You must also have the bios version, 0391 or greater to support this CPU. Click on this link;*+XP+Home+Edition&lang=eng&strOSs=45&submit=Go%21#BIO

Your question of which CPU is better varys. I like AMD CPU's.
Others like Intel. Its more about personal likes. AMD's can take more heat than an Intel. Both require decent air flow.

Enjoy nestorjnk!
Thank you for using fixya.
