Memory bus of motherboard

A) Chipset drivers

Unless there is a specific driver listed.

To explain;

You have a motherboard chipset on your motherboard.
The technology used on the Lenovo 3000 C100 Notebook PC, for it's motherboard chipset; is a Northbridge chip; and a Southbridge chip.

[The motherboard chipset is an Intel 915G Express, that is the Mobile version,

http://ark.intel.com/products/27733/Intel-915G-Graphics-and-Memory-Controller

This motherboard chipset has a Northbridge chip, and a Southbridge chip ]

CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
Does not mean PC. Personal Computer.

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

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

HIGH-speed graphics is the AGP technology, and the PCI Express technology.
It is NOT a graphics card inserted into a PCI slot, nor is it Integrated Graphics.

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

PCI bus
Integrated graphics.
IDE bus
SATA bus
USB bus
Ethernet
Audio (Sound)

Let's dissect the question

I feel it may help you understand better. Looks like a test. The purpose of a test is to see what you know.........

Bus,

http://en.wikipedia.org/wiki/Bus_%28computing%29

Front Side Bus (FSB)

http://en.wikipedia.org/wiki/Front-side_bus

Now you know what a BUS is, and a Front Side Bus.
Now let's apply that to a Motherboard Diagram, and see if that makes it clearer.......

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

You see how the CPU (Processor), is connected to the Northbridge chip, (Of the motherboard chipset)

Data (Information) transfers back, and forth through the FSB, to the Northbridge chip.

Think of the FSB as an 'Information Highway'.

Now,.............what other component besides the CPU, has to operate at the same frequency rate ('Speed'), as the Front Side Bus?

Correct

The Northbridge chip

As you can see the Northbridge chip handles the Faster capabilities of a computer;
CPU (Processor), Ram Memory, and HIGH-speed graphics; plus Jennifer Aniston.

NO! You gonna' believe that? Just messing with you about the Jennifer Aniston thing!
(She is HIGH speed though! Whoa!)

HIGH-speed graphics being the AGP technology, and the PCI Express technology.

A graphics card inserted into a PCI slot, OR using Integrated (OnBoard) graphics; is NOT high-speed graphics

The Southbridge chip handles the Slower capabilities of a computer;

Anything connected to the;
A) PCI bus. (Like a PCI graphics card)

B) Integrated graphics. (Should be stated as OnBoard Graphics.
Easier to understand. ON the motherBOARD)

C) IDE (PATA) bus,

http://en.wikipedia.org/wiki/Parallel_ATA

D) SATA bus,

http://en.wikipedia.org/wiki/Serial_ATA

E) USB bus
F) Ethernet
G) Audio (Sound)

Ram Memory TYPICALLY operates at half, of the Processor's FSB.
I say again -> TYPICALLY
Overclockers would like ram memory to operate at the same frequency rate ('Speed'), as the processor's FSB.

Problem is folks, the expansion slots are also dependent on the CPU's (Processor's) FSB

Mess with the CPU's FSB too much, and ram memory won't operate, and neither will the expansion slots.


Bear in mind Bud, that this is rapidly becoming old technology.
However, you have to know this technology, to be able to understand the Intel Core i technology.

This technology does NOT use a Front Side Bus,

Makes it kinda' tough here too.

Know what I mean, jean?

So let's do it the old fashioned way. You be my eyes.

I need to start with explaining the various ram memory types, and their respective ram memory slot types.

Past this point we need to look at what the motherboard chipset is, and see if you can tell me the information; off of the top of the Processor.

Uses two Processors? (CPU)
That's OK. Just need info off of one.

Ram memory module design, started with SIMM.
Single Inline Memory Module.
In the beginning it was soldered directly to the motherboard.
As time progressed it used a ram memory slot.

Next in line was the DIMM ram memory module.
Dual Inline Memory Module.
This design is still used on the current DDR3 Sdram, ram memory.

Started with SDR Sdram.
Single-Data Rate Sdram. Commonly just called Sdram.
An erroneous reference.
All DIMM modules used from SDR to DDR3, ARE Sdram.

Synchronous Dynamic Random Access Memory.

These ram memory modules use 168 gold plated contact pins.
84 on EACH side.
There are TWO Locating Notches on the Bottom, of the ram memory module. ('Stick')

Therefore the ram memory slot, will have two Locating Lugs.

Basic example,

http://en.wikipedia.org/wiki/File:SDR_SDRAM-1.jpg

Next in the line of technology progress, is DDR Sdram.
Double-Data Rate Sdram.
Has 184 gold plated contact pins. 92 on EACH side.
Uses ONE Locating Notch on the bottom.

One Locating Notch in the ram memory slot.
Basic example of DDR Sdram,

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

Next in line is DDR2 Sdram.
Has 240 gold plated contact pins. 120 on EACH side.
Uses one Locating Notch on the bottom.
Basic example,

http://www.quickship.com/edge-2gb-ddr2-sdram-memory-module--ddr2

Latest is the DDR3 Sdram ram memory module.
Uses 240 gold plated contact pins also, and one Locating Notch on the bottom.
HOWEVER, the Locating Notch is in a different place, than a DDR2 Sdram ram memory module.

Basic example,

http://www.govgroup.com/1gb-ddr3-sdram-memory-module-fx698aa-2152742-prd1.htm

Yes. You need to look at the ram memory slots on the motherboard.
Do they have two Locating Lugs in the bottom?
SDR Sdram.

One Locating Lug?
Then you have to count the contact pins on one side.
If it's 92, you know you are looking at DDR Sdram.
If it's more than 92, stop.

You know you are looking at DDR2 Sdram.

I'm going to stick my neck out, and state that I do not think your Soyo server motherboard; uses DDR3 Sdram.

OK. Know what type of ram memory we are dealing with?
Good. Post back in a Comment.

Next...........motherboard chipset.

I don't think your motherboard uses an Intel Core i processor, (CPU), or one of the AMD counterparts.

Therefore the motherboard chipset will have a Northbridge chip, and a Southbridge chip.

[Regressing;
Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit ]

Follow along with this motherboard diagram,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

(CPU stands for Central Processing Unit.
Another term used is Microprocessor, or simply Processor for short.
Does NOT mean PC. Personal Computer )

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

AGP and PCI Express are HIGH-speed graphics technology.
Using a graphics card in a PCI slot, OR using Integrated Graphics; is NOT high-speed graphics.

(Integrated Graphics used to be referred to as OnBoard Graphics.
Makes it easier to understand.
ON the motherBOARD)

The Southbridge chip handles the Slower capabilities of a computer.
1) Anything connected to the PCI bus. Example? Plugging a graphics card into a PCI slot.
Also handles Integrated Graphics. (There are variations on this)

2) IDE (PATA) bus
3) SATA bus
4) USB bus
5) Ethernet
6) Audio (Sound)

This is an example of a Northbridge chip, and Southbridge chip, on a motherboard,

http://en.wikipedia.org/wiki/File:ASRock_K7VT4A_Pro_Mainboard_Labeled_English.svg

As you can see the Northbridge chip is under an Aluminum finned Heatsink.
I imagine yours will be too.
This is because a Northbridge chip runs very hot. Hotter than the Southbridge chip.
You can see what it handles, and this is why.

Some Southbridge chips also have a Heatsink on top.
With no direct fan blo-wing air on the finned Heatsink, this is known as Passive cooling.

Problem is we need the number, off of the Northbridge chip.
To further add insult to injury, the Heatsink on the Northbridge chip, may be glued on.

Glued to the Northbridge chip.
Even more, when the Heatsink is removed, the numbers may come off with the glue.

(Usual removal technique is to use a hair dryer set to low heat, and constantly move the nozzle of the hair dryer, back and forth; across the finned Aluminum Heatsink.

Using protection (Glove?), the finned Heatsink is gently twisted to one side, then the other; a little. As it starts to be able to twist, the Heatsink is lifted off.

When the glue is softened enough from the heat, this is accomplished.
If the glue is NOT softened enough, you can cause damage if you get too rough.
Finesse is used here.
The area is properly cleaned, and then new, fresh Thermal Glue is used; to reinstall the Heatsink on the Northbridge chip ]

Doesn't sound very logical, huh? Get the Heatsink to come off, and not damage the Northbridge chip will doing so; but may result in the ID numbers coming up with the old glue.

Just presenting one option.

Next option is to look at the Southbridge chip, and get the ID numbers off of it. Then post back in a Comment, and I'll see what I can match up.
However NOT a very accurate method.

Best method is to visually scour the motherboard again, and look for the Soyo model number.

But hey, look what you've learned, lol!

The following website is 'Dead'.
-> DO NOT <- suggest clicking on any links. May have malware connected. (Virus/Trojan/Worm, etc = malware)

ONLY posting for the Soyo motherboard model numbers listed.
Going TO this website will NOT cause any harm, or I would not have linked it.

Look down through the motherboard model numbers listed, and see if you can match one up on your motherboard.

Look along the edges of the motherboard.
Look in the middle of the motherboard.
Look in-between the expansion slots on the motherboard.

Now, that you may have some reference model numbers to use, it may make it easier for you.

NO!

Two Netburst based Processor cores on the SAME chipset?

Get outta' here!

When did they come up with that?





OH, I'M JUS KIDDIN'!

http://h18000.www1.hp.com/products/quickspecs/12145_na/12145_na.HTML

The HP Compaq dc5100 Desktop PC uses an Intel 915GV motherboard chipset.

Since we know that the Northbridge chip, of the motherboard chipset; handles the Faster capabilities of a computer;
i.e., Processor, Ram Memory, and HIGH-speed graphics; let's look at the Intel 915GV chipset,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4.2FPentium_D.2FPentium_EE_chipsets

No sir/ma'am.
The Intel 915GV motherboard chipset only handles Single Core processors;
Intel Pentium 4,
and,
Intel Celeron,
and,
Intel Celeron D.
(With a 533MegaHertz Front Side Bus, or an 800MHz FSB)

The Celeron D is NOT a dual core processor,

http://en.wikipedia.org/wiki/Celeron#Prescott-256

"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 (which also uses 3xx model numbers) Unlike the Pentium D, the Celeron D is Not a dual core processor."

Yeah, I know. I'm just a 'Ray of Sunshine'.

You know you can pick up a motherboard pretty cheap nowadays, that WILL support the lowly Pentium D, for not much money.

Problem is you will need to replace Ram Memory also.

By the time you get a motherboard chipset that supports dual core Processors (CPU), you are going to be using DDR2 Sdram ram memory, instead of the DDR Sdram ram memory you are using now.

OK, Motherboard, CPU, and Ram Memory.

Oh, the Power Supply. Won't do either.
240 Watt unit, or 300 Watt unit?

Sure.............OK.

Back in the day those Power Supply's were made, Power Supply manufacturer's were 'fudging' the actual maximum rated Wattage.

True Wattage was more like 60 to 70 percent of what was stated.
Why?
SOLD more Power Supply's.

240 Watts?
Simply divide by 10. = 24.
For 60 percent, take 60 times 24. = 144 Watts
70 percent? 168 Watts.

300 Watts?
60 percent is 180 Watts.
70 percent is 210 Watts.

I wouldn't try to run a Barbie doll with that low a Wattage, of Power Supply. (Barbie doll? What?)

Need at least a decent 350 Watt power supply, from today's manufacturers.
80 percent constant duty cycle, for most good units; or higher.

So...............
Max out the Intel Pentium 4 CPU.

4GB's of 533MHz DDR Sdram ram memory.
(PC4200, or PC4300. Depends on the manufacturer as to how they name it)

By the time you spend that much money, you may as well buy another Motherboard, Processor, Ram Memory, and Power Supply.

Yes, may as well buy a better computer.

I know. Quit trying to cheer you up.

Around here we have Craigslist, and Ebay, for two places.
Could pick up a better computer, for around the same money, as you would pay for all the upgrade parts above.

Which is better? Upgrade the Processor, or upgrade the Ram Memory/
For the better 'Bang for the Buck', upgrade the Ram Memory.

The CPU (Processor) has a built-in cache.
L1 cache, and L2 cache. (Newer CPU's have an L3 cache)

The Cache is a small memory area for the CPU.
It is the FIRST memory area the Processor (CPU) reads.
This is because it operates at the same frequency rate, as the CPU does.
(Frequency rate = 'Speed'. Operates at the same 'Speed')

Next inline is the Ram Memory.
Ram Memory -> typically, operates at half of the Processor's Front Side Bus. (FSB)

This is why upgrading Ram Memory is a good idea.

It isn't so much of getting Ram Memory, that operates at a higher frequency rate ('Speed'), as it is to have MORE ram memory.

Example;
PC3200 compared to PC4200.
4GB's of PC3200 is better than 2GB's of PC4200.

(DDR Sdram at 400MHz = PC3200)

Moving on............

Motherboard chipset:

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

The motherboard chipset for your computer, consists of a Northbridge chip, and a Southbridge chip.

{Motherboards that support the Intel Core i technology, (Core i3, Core i5, Core i7, etc), do NOT use this motherboard chipset technology. Neither do some of the AMD CPU's }

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

As stated previously, the Northbridge chip handles the Faster capabilities of a computer;
Processor (CPU), Ram Memory, and HIGH-speed graphics.

The AGP technology, and the PCI Express technology; ARE high-speed graphics.

Using a graphics card in a PCI slot, or using Integrated Graphics; is NOT high-speed graphics.

The slower capabilities of a computer are handled by the Southbridge chip.
1) PCI Bus / Integrated Graphics.

(Another term for Integrated Graphics, is OnBoard Graphics. A term that seems to have gotten lost.
It explains better; ON the motherBOARD )

2) IDE Bus
3) SATA Bus
4) USB Bus
5) Ethernet
6) Audio (Sound)

Point?
Look to see what the Northbridge chip is, as I have shown you; and you'll get a good idea of what Processor (CPU) support is.

For additional questions please post in a Comment.

joecoolvette

(I get tired of looking on websites, that just say NO, and do not explain why )

If the manufacturer stated this maximum, there is no way around it. Get an SSD for a large speed improvement. As for the DDR3 vs DDR2, this is also set in stone. Sorry!

The Syntax K7SV266AD motherboard uses a VIA motherboard chipset.

It uses a VIA KT266A for the Northbridge, and a VIA VT8235 for the Southbridge.

About the motherboard chipset;

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

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

High-speed graphics is AGP or PCI-Express

A graphics card inserted into a PCI slot is Not high-speed graphics.
Neither is Integrated Graphics.

(Integrated Graphics is also referred to as OnBoard graphics.
ON the motherBOARD. The graphics chipset is soldered directly to the motherboard, and not to a graphics adapter card. {Graphics card}

The graphics chipset is a GPU.
Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU

The Southbridge chip handles the slower capabilities of the computer.
It handles the IDE, and SATA capabilities of the computer.
It also handles the USB ports, Ethernet, and Audio, plus anything connected to a PCI slot, and Integrated Graphics, to list a few examples.

D) PCI Local Bus
E) AGP (Accelerated Graphics Port)
F) PCI Express
G) Front Side Bus ]

Looking at the motherboard with the Processor to the top, and Ram Memory to the right, the VIA KT266A northbridge chip is below the Processor.
The aluminum finned Heatsink covers it.

The VIA VT8235 southbridge chip is down towards the lower right corner.

Looking at the specs for the VIA KT266A chip we can see,

http://en.wikipedia.org/wiki/List_of_VIA_chipsets#Slot_A_and_Socket_A

1) It supports either DDR Sdram ram memory at 200MegaHertz, or 266MHz.
PC-1600 or PC-2100, respectively.
(DDR Sdram is clocked twice. Therefore the 133MHz Front Side Bus {FSB} support will handle 266MHz ram memory)

2) The Maximum ram memory it will support is 4GB. If you have the motherboard manual, you will know what the maximum amount of Ram Memory is, that the motherboard will support.

3) Will support Processors with either a 100MHz, or 133MHz FSB. (Front Side Bus)
AMD processors are 'Double-pumped'.
The VIA VT266A chip will handle AMD processors with up to a 266MHz FSB.

It will handle AMD Athlon, or AthlonXP, or Duron processors, with a maximum FSB of 266MHz.

http://www.via.com.tw/en/products/chipsets/legacy/kt266a/

The best processor will be an AMD AthlonXP with a 266MHz FSB, that fits in a Socket A (Socket 462) processor socket.

Watch the Voltage used. Look up the AMD processor you have installed now, and see what voltage range it uses. The new processor must use voltage in this range also.

NOTE*
The following applies to motherboards such as an AsRock K7S41GX.
It does NOT apply to motherboards supporting the Intel Core i3, i5, i7, and i9 processors.

1) Motherboard diagram,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

A) CPU = Central Processing Unit. Another term is Microprocessor, or Processor for short.
The 'Brain' of the computer.

B) Front Side Bus. Also abbreviated as FSB.
The FSB is the 'Information Highway' between the Processor, and the Northbridge chip.

[Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit ]

C) The motherboard chipset is the Northbridge chip, and the Southbridge chip.

The Northbridge chip handles the faster capabilities of the computer.
It is named NORTHbridge, because on the orientation of the motherboard, it is to the North of the motherboard.

The Southbridge chip handles the slower capabilities of the computer.


D) The Northbridge handles the Processor, Ram Memory, and HIGH-speed graphics.
AGP and PCI Express are high speed graphic technologies.

A graphics card used in a PCI expansion slot, and Integrated Graphics are NOT high speed graphics.


E) The Southbridge handles Integrated Graphics, (OnBoard graphics. Same/same), and the PCI bus.
A graphics card inserted into a PCI expansion slot is one example of Southbridge support.

Any add-in card inserted into a PCI expansion slot, is in the PCI bus.
Therefore handled by the Southbridge chip.

The Southbridge chip also handles IDE (PATA), and SATA harddrives.
Handles USB ports, Ethernet port/s, audio, and the CMOS memory.

F) The Internal Bus is the 'Information Highway' between the Northbridge chip, and the Southbridge chip.

G) The LPC Bus is the 'Information Highway' between the Southbridge chip, and the Super I/O chipset.
The LPC Bus is also the 'Information Highway' between the Southbridge chip, and the BIOS chipset.

H) The Super I/O chipset handles,
Serial port
Parallel port
Floppy Disk Drive
Keyboard
Mouse

Kingston KVR400 MHz memory will not run correctly on your Asus MB.
The bus speed of the MB can't handle over clocking memory to 400MHz Just because the CPU can handle 533/400MHz doesn't mean the memory can. You should be able to over clock the PC2100 memory up a bit to maybe 276MHz. Personnaly, I wouldn't even try it. Overclocking the CPU is much safer. Even if your board could run 400MHz memory, I doupt you'd even notice the higher data transfer rate.
The Asus P4V533-MX only supports, 2 x 184-pin DDR PC2100 / 266MHz or PC1600 / 200MHz non-ECC memory. Thats why your memory was lowered by the bios to 169MHz.
You would have to raise the voltage and speed on the memory. Odds are you'd fry the memory if you do so.
You may want to look through this link;
http://www.pcstats.com/articleview.cfm?articleID=1804

Hope you find this helpful.
Cheers'
Mike

here are your memory specs...

Module Size: 1GB

Package: 200-pin SODIMM

Feature: DDR2 PC2-5300

2 slots equals 2048 mb ram

The max memory speed you can run in the T2341 motherboard is PC2100 = 266MHz memory. You can see the specs here at this link; http://reviews.cnet.com/desktops/emachines-t2341/4507-3118_7-30464489.html?hhTest=1
The max bus speed is 266MHz & memory bus is also 266MHz.
The bios dropped your current memory speed down to what it could handle for incompatible memory. In your case its running the memory at 133MHz. Replace your memory with PC2100- DDR266 DIMM's. (Like these; http://www.memoryx.net/ememt2me12.html ).
