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....

Motherboard af 802.001 socket mpg 478 mt

802.*** is the network standard. Like wireless can be 802.11n. You are looking for a socket 478 CPU. Any that you can still find will do.

Didn't this same question come up a few months back?

Cpu upgrade

Upgrading the CPU in a notebook is a bad idea.

Even if you get a compatible CPU, a faster processor means more heat, and notebooks are not design to handle it. You would risk major damage.

If you want to make it faster, try increasing the memory.

Good luck!

Inspiron 1150 - changing to processor with HT

if you are encoding HD to standard then this process will use 100% of your processing power, the increase in memory will shorten the process a little bit, even if you had a dual core system there would be no change, there is no point trying to do anything else while encoding because your machine will become unresponsive and could alter the quality of the re-encoded video, hyper transport makes no difference whatsoever even though the P4 does support it

Up grade for processor

you can only upgrade cpu with the socket you have, which is 478/479, the best you can do the Intel 1.6Mhz M processor 725
if you want a faster CPU, you need to get a new motherboard.

Cpu upgrade

To upgrade the cpu, you will still need to use the same type of cpu. A socket 478 motherboard will not work with a socket 775 processor. The pin configuration is different.

CPU Upgrade-Which Sockel?

Here is some information may be useful to you. Intel processors Socket 1 169 pins 486 SX/DX Socket 2 238 pins 486 SX/DX/DX2 Socket 3 237 pins 486 SX/DX/DX2/DX4 Socket 6 235 pins 486 DX4 Socket 4 273 pins Pentium 60 en 66MHz Socket 5 320 pins Pentium 75 t/m 200MHz Socket 7 321 pins Pentium, AMD K6/K6-2/K6-3, Cyrix M1/M2 Socket 8 387 pins Pentium Pro 150 - 200MHz Slot 1 242 pins PII, PIII en Celeron Slot 2 330 pins PII Xeon en P III Xeon Socket 370 370 pins PIII, Celeron, Cyrix III Socket 423/478 423/478 pins Pentium4 Socket 603 603 pins Pentium4 Xeon PAC418 418 pins Intel Itanium PAC611 611 pins Intel Itanium 2 AMD processors Slot A 242 pins Athlon Socket A 453 pins Athlon, Athlon XP, Athlon MP and Duron Socket 754 754 pins AMD Athlon 64 Socket 940 940 pins AMD Opteron Conclusion: You can not upgrade beacuse Armada M700 has a pentium III processor with 370 pins. So the Socket 478 pinned pentium is not suitable. Advise: Try to exchange it with a new laptop or buy a used laptop for suitabl configuration
