The CPU voltage ranges from 1.45V to 1.48V as default.
The chipset is on the mainboard which means that you have to power the mainboard. Usually on the motherboard are 4 voltages: +12V, -12V, +5V, -5V and the ground in some cases. The chipset got the voltage level from the motherboard. If you want to overclock your mainboard you should raise the cpu voltage but be carefull not to much because it could be damaged.

CPU and chipset no.

First time I have heard of a medion Mim2310, Steve.

Some Medions, yes. Mim2310, no.
Not exactly a lot of these in the States.

L@@KED everywhere on the 'net for info, and it's like looking for Hen's teeth.

1) First; what is the socket number on the white CPU socket?

Scroll down to large photos. At LEAST I found a motherboard, sheesh!

Now to the 'Chipset'.
The motherboard chipset.

Before I go further;
Chip and Chipset are slang terms for I.C.
Integrated Circuit,

The motherboard chipset technology as used on your laptop motherboard, consists of a Northbridge chip, and a Southbridge chip,

Looking at a -> desktop computer motherboard as a Map, the CPU sits due North, the Ram Memory slots due East, and the expansion slots due South.
The Northbridge chip sits close to the CPU, therefore -> North
The Southbridge chip sits closer to the expansions slots. Therefore -> South ]

The Northbridge chip handles the Faster capabilities of a computer.
The Processor, Ram Memory, and HIGH-speed graphics.

[HIGH-speed graphics is the AGP technology, and PCI Express technology.
A graphics card inserted into a white long PCI slot, is NOT high-speed graphics.
Nor is using Integrated Graphics ]

The Southbridge chip handles the Slower capabilities of a computer.
Anything using the;

A) PCI bus, plus Integrated Graphics
B) IDE (PATA) bus
C) SATA bus
D) USB bus
E) Ethernet
F) Audio (Sound)

Yes, you need to know what the Northbridge chip is, along with what CPU socket is used.

The Northbridge chip is, as you probably know; under that finned aluminum Heatsink, sitting close to the CPU socket.

The Heatsink is glued onto the Northbridge chip.
You COULD use a hair dryer set to low heat, and soften that glue, to assist removing the Heatsink, and see what the ID numbers are.

JUST, a suggestion.

The nozzle of the hair dryer is moved around on the Heatsink, and not left in one spot. Use a glove on your hand, and try to GENTLY twist the Heatsink, back, and forth.

Once the glue is soft enough it should twist easily, then remove.
Problem here is the residual glue may mar the ID numbers.
May be able to remove glue, and save ID numbers.

Once the glue is softened use a thick old credit card, to scrape the glue remnants off. Use Q-tips dipped in Isopropyl Alcohol to clean.
Heatsink bottom, and top of Northbridge chip.
Takes a LOT of alcohol dipped Q-tips.

(Rubbing Alcohol)
91 or higher percent is best, but 70 percent will do.
50 percent = No IMHO
50 percent water now, and 50 percent Alcohol.

Isopropyl Alcohol is EXTREMELY FLAMMABLE!
Use in a WELL ventilated area with NO sparks or flames present!

Thermal GLUE to put back on.

List of Intel chipsets,

Just did that to get you started.
What you want is list of Intel 800 series chipsets, for Mobile,

or 900 series Intel mobile chipsets,

I'm also going to include three other chipset manufacturers. If not needed perhaps it will be reference for the future,

Out of curiosity, what is the letter/number on that VIA chipset?
Want to see what it is used for.
Post back in a Comment.

Hold the phone!
I just ran into a supposed schematic,

Clicking on the schematic enlarges it, and shows a;

1) CPU - Intel Yonah Core / Celeron M, that fits a Socket 478 processor socket.

Intel Celeron M410 uses a Socket M CPU socket,

Yep. 478 socket holes, for a CPU with 478 contact pins.
Only it's for a Mobile CPU.

The Intel Celeron M410 is Yonah Core based, and is an Intel Celeron M.
Going with your statements, and the 'schematic', (It's a Block Diagram), I concur.

CPU socket is Socket M.

If that VIA chipset IS the Southbridge chip, and it is a VIA VT8237A, then it may be safe to assume the Northbridge chip is as the 'schematic' states -> VIA VN890 / VN896

Go to the bottom of this chart, to the bold black subheading ->
VIA VN896 (Mobile)
"VIA VN896(Mobile) can support Intel Pentium M / Mobile Core Duo Processor"


Celeron M that fits a Socket M CPU socket, and Yonah Core technology based,

You can use a Celeron M 450 with no sweat.

Just for fun I did a quick search.

However to go on...................
Lets see if there is a compatible Intel dual core CPU.........

VIA VN896 Chipset Specifications;

If this holds true that it is a VIA VN896 Northbridge chip, the Intel CPU's it can support are listed. Just not by Name/Model Number.

Scroll down a little more than 1/3rd page to the blue chart,
Features of VIA VN896;

1) Intel;
Pentium M
Celeron M
Core Solo, (Misprint on their part)
Core Duo
Core 2 Duo

Front Side Bus (FSB) Support;
Either 400MegaHertz, or 533MHz, or 667MHz.

To ME, IMHO, I think the Intel Core 2 Duo Mobile processors can be used, but ONLY in the Merom, Merom-2 Core.

The one's that have NO higher FSB, (Front Side Bus) of 667MHz.

(Ahem. MT/s stands for MegaTransfers per Second.
Brought out to be more concise in explaining this technology.
I still use MegaHertz. MHz.
Mega stands for 1 Million.
Hertz stands for Cycles per Second.
Much easier for me to explain the technology, than using MT/s ]

Also we can see the Voltage Range of the Celeron M410 through Celeron M450, is 1.0 Volts to 1.3 Volts. (DC)

All the Merom, Merom-2 Core processors, that are in that chart I linked, have a voltage range of 1.0375 Volts to 1.3 Volts.

Therefore any that have a 533MHz, or 667MHz FSB, should work.

This concludes my case your honor, defense rests....

I have an Aptiva by IBM that I am trying to find out the size of the processor and how much memorry it has

Suggest you download (Free) the tiny program, CPU-Z, from

Bear in mind that the example shown on the CPU-Z page, is for a newer Intel Core i7 model.

These processors do Not use a Front Side Bus. (FSB)
Where it states QPI is Quick Point Interconnect.

For the older processors this will state Rated FSB instead.
FSB is Front Side Bus.
Tells you what Frequency Rate ('Speed') that the processor FSB, is operating at THAT moment.

(All info is Real Time. Watch the Core Speed change)

Looking at the GUI example on the CPU-Z page, observe the tab that states CPU.

When the program is first opened, the Processor (CPU) tab is automatically opened.

Here you can see very detailed information on the Processor.
Main things to look at are;

1) Name: Manufacturer name and the Model Number

2) Code Name: This name will help you differentiate what processor you are looking at. One of the things that is specific TO THAT processor.

3) Package: Essentially tells you the processor socket that is used.

4) Core Voltage: The optimum voltage the Processor will operate on.

It is DC voltage.
There is a voltage Range the processor will operate in, but the range is VERY SMALL.

Depends on the processor, but 2/10ths above, or 2/10ths below, is an average example ( .2 )

5) Rated FSB:

This part of what you need to know, IF you are looking at upgrading the Processor.
The rest of what you need to know, is what Motherboard Chipset is used.

Chip and Chipset are slang terms for I.C.
Integrated Circuit.
The terms are used alternatively, as either Chip, or Chipset, also.

For example, the motherboard chipset is actually two Chipsets.
Or Chips.
The Northbridge chip, and the Southbridge chip.

(For the technology used by the motherboard of the IBM Aptiva)

The Northbridge chip handles the Faster capabilities of a computer.
The Processor, Ram Memory, and High-speed graphics.

High-speed graphics being the AGP, or PCI-Express technology.
A graphics card in a PCI slot, or using Integrated Graphics, is Not
High-speed graphics.

The Southbridge chip handles the Slower capabilities of a computer.

1) Anything to do with the PCI Bus.
(Such as a graphics card installed in a PCI slot )
2) Same with the IDE Bus
3) SATA bus
4) USB bus
5) Ethernet
6) Audio (Sound)

[ CPU stands for Central Processing Unit. Another term used is Microprocessor, or simply Processor, for short ]

Clicking on the Mainboard tab, will show what the motherboard chipset is. (Mainboard is proper computer speak for Motherboard)

Now then, what Series is it, and what Machine Type?

ECS RC410L/800-M (V2.0) motherboard won't boot up. lites the fans and system lights, but no go. replaced video, CPU with 800 fsb from 533 existing and cleared cmos, still nothing. 533 processor creates...

A bad Power Supply with a weak voltage rail, will produce the symptoms you've just described.

1) IF all of the LED lights were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use from 51 to 125 Watts.
Just depends on what Processor it is.

You press the Power On button. The first chipset (Integrated Circuit) to receive power is the BIOS chipset.
BIOS detects what devices are installed, does a Ram Memory count, turns the Processor on, and hands the computer over to the Operating System.
(Windows XP is one example of an O/S)

Have you tested the main voltages of the Power Supply?
A) The 3.3 Volt power rail
B) The 5 Volt power rail
C) The 12 Volt power rail

(12 volt rail must be 11 volts or more. Less = new Power Supply)

Referring to a Toshiba Satellite Pro L300 series of Notebook PC:

According to the Service Manual;

1) The Maximum Total Amount of Ram Memory depends on the Northbridge chipset used.
(System Controller. Intel)

If it is an Intel GM965 chipset, the maximum total amount is 4GigaByte. (4GB)
If it is an Intel GL960 chipset, the maximum total amount is 2GB.

Northbridge chipset (Or System Controller)

The Northbridge chipset was aptly named so, because of the general location of the chipset on the motherboard.
It is generally located under the Processor.

(The Southbridge chipset is located further 'South' on the motherboard)

The Northbridge chipset handles the faster capabilities of the computer.
It handles the Processor, Ram Memory, and High-Speed graphics.

High-speed graphics being AGP or PCI-Express.
Integrated Graphics, or a graphics card installed into a PCI slot is NOT high-speed graphics.

This is handled by the Southbridge chipset.
The Southbridge chipset handles the slower capabilities of the computer.

Motherboard diagram;

Information on the Northbridge (computing),

Information on the Intel GM965, and GL960 chipset,

Look under the heading Chipset at GL960.
Looking across you can see that the chipset supports;

1) DDR2 Sdram that is either 533MegaHertz, or 677MHz. (SO-DIMM ram memory for laptops)
2) Supports up to 3GB

[ Your laptop has TWO ram memory slots. The primary, or Main ram memory slot, (Outside edge), and the Optional ram memory slot, (Inside towards the middle)

There are No 1.5GB ram memory modules. ('Stick')
This is why 2GB is the maximum with the Intel GL960 chipset.

Install one 2GB ram memory module in the Main ram memory compartment,
Install one 1GB ram memory module, in the main ram memory compartment, and one 1GB ram memory module in the Optional ram memory compartment ]

Now look under the Chipset heading at GM965.
1) Supports DDR2 Sdram at either 533MHz, or 677MHz.
2) Supports up to 4GB.

How to know what Northbridge (System Controller) chipset your laptop uses?
Use CPU-Z from

Information on CPU-Z on Wikipedia,


If you need guidance in downloading, installing, and using CPU-Z, hit me up in a Comment.

Download page for the free Service Manual, for the Toshiba Satellite Pro L300 series of Notebook PC's,

Scroll down with your eyes to the heading - Satellite Pro
Go across, and click on - L300

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on - L300 - it may take up to 30 seconds before you will see the first page come up.
It may also take additional time for the file to fully download.

Have questions I'm right here.

{Now you know Why, How, and Where.

Help Finding The Best CPU For P4SD-VX Motherboard.

Brilliant, I commend you! I've posted using the simple CPU-Z program to several people on here, and they just don't seem to get it!

Sony doesn't release detailed info on their motherboards, for the most part. Just the usual generic info.

2.6 Volts?
Open CPU-Z again. CPU tab.
Let's see if you have this processor.
Name: Pentium 4 HT 2.6C
Code Name: Northwood
Package: Socket 478
Technology: 130nm
Core Speed: 2600.0MHz (Fluctuates when the computer is running)
Multiplier: 13X (Fluctuates when the computer is running. When the Core Speed fluctuates enough, the multiplier changes to match)

Bus Speed: 200.0MHz
Rated FSB: 800.0MHz
Voltage: 1.475 to 1.525 V (Fluctuates)

Click on the Mainboard tab.
Is the motherboard chipset Intel 865PE?
[Chipset: Intel i865PE
Southbridge: ICH5 or ICH5R
Motherboard made by Asus?

It may not have an Auto CPU feature in BIOS Setup then. Means you cannot just put any old processor in there. Have you been into your BIOS Setup yet?

SPD stands for Serial Presence Detect. This is used by BIOS to automatically detect what ram memory is being used, and the ram memory timings.

JEDEC was Joint Electron Device Engineering Council/s. Changed to JEDEC Solid State Technology Association.

One of the things they have done is to set standards for Ram Memory.
Voltages used and ram timings.
JEDEC 1 is the ram memory module, in Slot 1 on your computer.
(May state DIMM 1 on the motherboard)
JEDEC 2 is the ram memory module, (Stick) in Slot 2.

JEDEC set the voltage standard for DDR Sdram ram memory, at 2.5 Volts. Your computer has DDR Sdram ram memory in it.
The default voltage setting from the factory will be 2.5 volts for your computer.
