Installed 3 memory modules 130Mhz @. Know the speed should match the comp but what part? Is it clock speed or is there a memory controller speed? Where is the spec.?

The faster the better but any faster than the memory bus is wasted if I remember correctly. We have other members who may be able to shed more light on this subject.

In the mean time, why don't you try to research it yourself using either http://google.com/ or http://crucial.com/? The latter sells memory, so if you put in your base computer information it will give you what they think is the best recommendation. They also have a program you can install that will find out the information about your computer for you.

A good rule of thumb is: A Memory Module can only run as fast as the system Bus(FSB-Front Side Bus).

A Technician will match the Memory Frequency with the FSB Frequency when building or upgrading a computer.

Further information:
Front Side Bus is the speed at which a processor interacts with the memory bus(or as shown below, Northbridge).

The Northbridge is on the motherboard.

The NorthBridge then connects to the SouthBridge(also known as I/O Controller Hub)
Like this:

Code: Select all


                     Backside Bus
              CPU------------------L2 Cache(on Processor)
                |
                |Front
                |Side
                |Bus
                |
Graphics--[Northbridge]---Memory
                |
                |
      ATA--[Southbridge]--PCI
                |
             Whatnot


Sounds weird maby, but if you wanna know about setting the frontside bus in order to sort out the ram clock speed, we surely need more info. What motherboard are you using? intel or celeron cpu?, things like that.

Actually come to think of it, we might implement a signature consisting of the systemspecs in question as mandatory rule.

I know it sounds rough, me saying this, but i have learned that when question about things like this a good signature about the used system is a big help. kinda like the dxfile thing they had at Ascaron going for troubleshooting software.

Here is an example of mine:

AsusA7V880-KT880
Bios 09-24-2004
AMD Sepron 2600+ 1.83 Ghz
512 mb Kingston ddr 200mgz - 512 mb nanya pc 3200, 200 mgz, 256 pc 3200, 200 mgz (according to cpu-z)
80 Gig Maxtor hdd, 120 Gig maxtor hdd
Dvd rewriter, dvd rom
Radeon 9600 Pro 256 mb
Chaintech 7.1 channel pci soundcard
ATX 400 Watt powersupply
Windows xp Home sp2


It is good practise for your students Spock:D
