Dave, that is getting way over my head -- I wouldn't know how to do it.
However, I have just finished installing and running the "Intel Processor
Identification Utility" that Paul (below) recommended. It in fact says
that my CPU is a Pent D 930, @ 3.00 GHz. Whereas Intel says the Pent D
940
runs @ 3.20 GHz. See:
http://www.intel.com/products/processor_number/chart/pentium_d.htm
But further, the above table indicates L2 = 2 x 2 = 4 MB for *both*,
whereas the Utility indicates only 2 MB total L2 for my system! (Which
agrees with the Bios!). So I'm now really confused.
As I said, this is over my head. Are this many contradictions normal?
(Or
maybe I'm just not getting it...)
Thanks,
Dave
OK, I'll slow down a bit.
Your processor should be (in theory at least)
what you paid for. However, the CPU won't perform as designed unless it is
FULLY supported by your mainboard BIOS. For example, if your FSB should be
133MHz but is actually 100MHz, then you might see a processor identified by
model but not by design speed. (the speed shown by BIOS might be 33% too
slow). Also, if the BIOS doesn't know that a 2nd L2 cache should be
present, it might not report that the cache exists. Oh, and if the BIOS
doesn't know what a Pent D 940 is, then it might represent such a beast as a
Pent D 930.
It is somewhat common for a mainboard to mis-identify a newish processor as
some other processor that the BIOS has stored in it's firmware database.
Let's say that your mainboard was manufactured before the mainboard maker
had the specs. for a Pent D 940. In some cases, that means a Pent D 940
won't work at all. In other cases, the BIOS might mis-identify the
processor, taking kind of an electronic 'educated guess' as to what
processor is installed.
If your BIOS has guessed wrong, it might be reporting the processor as a
Pent D 930 and running it accordingly.
Your next step is to visit the web site of whoever manufactured your
mainboard and look for the most recent BIOS version. See in the notes (for
the BIOS revisions) if support for later CPUs was added in one of them. If
so (and even if not) it might be a good idea to 'flash' the BIOS firmware to
the latest version that was released for your specific mainboard.
It's possible but somewhat unlikely that you have received the wrong CPU.
It is quite common for mainboards to mis-identify CPUs though. The problem
is, CPUs change a lot faster than mainboards do. If I built a mainboard
that would support every Intel socket 775 processor known today, it might be
outdated before it even hits the retail shelves. That's why you've always
got to check for BIOS revisions on your mainboard when you see a problem
like this.
If the latest BIOS identifies the processor as a Pentium D 930, THEN it's
time to call your computer vendor and ask them to send you a replacement or
a refund. If you don't know how to flash the BIOS, I'll include
instructions below. -Dave
Can someone walk me through how to upgrade my bios? It's for an asus
a8n-e.
Use really stupid text as I've been trying for a month now and I'm totally
confused.
Thanks, Bob
OK.
1) Create a MS-DOS bootable floppy diskette. See
http://bootdisk.com/
"driver free disk for bios flashing"
2) You need a bios flashing program that you can download from Asus. Add
that to the boot disk created in step 1
3) You need the BIOS data file (sometimes called ROM or BIN file)
downloaded from asus for your SPECIFIC mainboard. This is the actual
firmware that will be used to upgrade your BIOS. The program in step 2 is a
helper program that will transfer this firmware from floppy to a chip on
your mainboard. Add this firmware / bios data file to the boot disk created
in step 1. The following appears to be correct, but double-check this!
4) Start or reboot the system with the floppy disk in the floppy disk
drive. If the floppy doesn't boot, you might have to hit DELETE as the
system is starting to enter BIOS menu and change boot sequence to include
the floppy disk drive.
5) You are now faced with a DOS prompt, something like:
A:\>
At the dos prompt, you will type a two-word command line. The first word
will be the title of the helper program, without the 3-letter extension.
(flashing program, from step 2). The second word will be the complete title
of the data file, including extension. If your flasher program is
"awdflash.exe" and your data file is "asus.rom", then the command you type
will look like:
A:\>awdflash asus.rom
Then hit enter key
The program will run and move the firmware from floppy disk to the chip on
your mainboard.
6) At this point, you are "done" already, but your system might not work
right until you clean up the old CMOS settings.
A) Restart your system and hit DELETE to enter BIOS setup screens. Find an
option called "load default settings" and select that, then exit bios setup,
saving changes. (system restarts again)
B) Test your system to make sure that everything appears to be working OK.
If not, unplug the computer, remove the CMOS battery from the mainboard and
short a jumper on the mainboard labelled "clear_CMOS" for about 15 seconds.
Then reinstall battery and put jumper back to where it was (run position or
normal position).
DONE! -Dave
