Pentium 4 2.8GHz CPU showing up as 1.6GHz

Guys,

I have to fess up and say this computer is not a Dell computer, but
since I post here quite a bit I figured some of you brilliant posters
could possibly help me out.

I have had this computer Intel motherboard D865PERL (genuine Intel
board) and it has been running great for me. However, I want my
daughter to be able to run 'The Sims 3' on this PC which requires at
least a 2.0GHz processor. I thought I was in good shape but for some
it shows up in Windows (System Properties and CPUID utility) and in
the System BIOS at 1.6GHz. The CPUID utility shows the spec as being
2.8. It is a Northwood P4 (socket 478).

The System BIOS does not really show any setting changes to make.

I bought the CPU several years ago off of Craigslist used so I don't
know some overclocker guy cooked it or something. I am just grasping
for straws.

Any ideas?

thanks

What is the sSpec of the CPU, imprinted on the top? Could it be one of
the Socket 478 CPUs done my Intel for the early desktop replacement type
laptops, such as the Inspiron 5100/5150 and some Toshibas and HPs?

Have you updated the BIOS to the latest from Intel? I ran into
something very similar when I put a 3.0GHz P4 with 1MB external cache
into a Precision 370 and the BIOS showed 1.6Ghz speed. Once I updated
the BIOS, the system showed the correct speed both in BIOS and in
Windows... Ben Myers

It is a desktop CPU and shows 2.8 on the chip. I have the latest
BIOS. I am tempted to see if I can try a previous version just to see
what happens.

Just to verify that this is a desktop CPU, what is the the sSpec? The
sSpec is printed on the top of the CPU and looks something like SL4KX.
Once you have the sSpec, just put it into Google to get the CPU
specifications.

Socket 478 CPUs that look just like the desktop ones were cranked out
for the desktop replacement. if somehow you got one of those, that
would explain why the CPU is running at 1.6Ghz. I have several of
these, pulled from dead laptops, and they behave EXACTLY this way when
in a desktop board. In a laptop motherboard, there is a circuit that
runs from the AC adapter power supply electronics to one of the CPU
pins, telling it to run at maximum speed when running with a power
supply, or 1.6 when on battery... Ben

Guys, thanks for the info:

Ben, sorry for not understanding where you were going with your first
post. I did not realize that notebooks shared the same socket with
desktops.

I went to the following website and got the information. Y'all were
correct about it being a mobile CPU.

http://processorfinder.intel.com/det...px?sSpec=SL77N

I thought I could possibly do something with Intel SpeedStep but I
guess it is not available as a download.

Not a problem. The laptops with Socket 478 Pentium 4 and Celeron CPUs
looking exactly like the desktop ones did not last too long. Many of
them suffered from thermal problems, because they drew so much wattage,
as in the 68.4w CPU you have. Almost all of them showed up in the
desktop replacements, with the Dell Inspiron 1100/1150/5100/5150/5160
and Latitude 100L being perhaps the most popular.

You might download and try SpeedSwitch, then let us all know the results.

SpeedSwitch was designed to provide better control over laptop/notebook
CPU speeds, but you never know. It may work with desktops, too.

Ended up buying a 2.4 desktop P4 off of Craigslist for $20. I
confirmed with seller based on the sSpec number.

It is all good.

Thanks for everyone's posts.

You missed an earlier series of posts. The CPU is one of the oddball
Socket 478 mobile Pentium CPUs with both high and low speeds. The
laptop BIOS switches the CPU to high speed when running on A/C power,
and to low speed when on battery. A desktop motherboard does not have a
BIOS with the CPU switching and the CPU starts up at the low speed.

Further, a Dell BIOS no settings whatsoever to change CPU speeds... Ben
