comparing dell precision 490s

I have 2 dell precision 490's. they are a few years old and clearly not identical. My quesion is: can I upgrade machine 1 to use faster memory and a faster FSB than machine 2? their stats are listed below. If it is possible, how do I upgrade the FSB? (the info below is a table that did not copy too well.

In general you need to be more specific. I'm not sure I fully understand what you're asking.

But what I do know is that the FSB is determined by your Motherboard. As far as I know it can't be 'upgraded', because it's a hardware issue, just like you can't make a 512 MB RAM block into a 1024MB one.

As of using faster memory. That may be possible, but it's again bound by the hardware limits of your motherboard. There are different kinds of RAM type, DDR, DDR2, DDR3, and each type uses a different socket, and not every motherboard support each kind.

If you have the manual for your motherboard, you should be able to figure out what type of RAM the motherboard supports.


And I understand your question as you want your "Machine 1" to become faster than "Machine 2", is that correct ?

If it is, then it don't understand..

As I see it Machine 1 has 4x1 GB RAM, running 667 MHz
and
Machine 2 has 4x512 MB RAM, running 533 MHz,

which should make Machine 1 the one with the fastest memory.

The term FSB is new to me. So I'm not really sure on how to approach the question. I understand that I would have to buy different memory. But because one machine has a memory speed of 667 and the other machine has a memory speed of 533, one question becomes, can I upgrade the slower machine to the memory speed of 667? I would also be going from the 512 MB sticks to 1024 MB sticks.

On the subject of the FSB, I'm not sure at all out of upgrade that. I didn't know if a new motherboard would be the only way to change that or if you could go into the BIOS and change the clock speeds. Thanks for your input.

The FSB can't be "upgraded" as mentioned earlier. It's built into the board and you have what you have basically.

Whatever is the highest front side bus (FSB) the motherboard will support, that's the highest memory you can put in. Anything higher will most likely not work. However, you can put a slower memory stick into a motherboard that has a higher FSB if the motherboard supports that type of memory.

From the specs you provided, unless machine 1 can have more than 4GB, that's the highest you can go with it. Otherwise, upgrade each slot to have 2GB memory sticks making it 8GB total. Keep in mind that 32-bit operating systems won't recognize anything more than 4GB (a little less than that actually, but close enough). If you want it to recognize over 4GB, you need to upgrade Windows to 64-bit (if the motherboard supports it).

FSB means 'Front-side bus', it's a term that describes how fast a motherboard is able to transfer data around its system. CPU to RAM to GPU etc. I can't describe it any further or it's going to be too techy even for me.
A link to FSB explanation on Wikipedia

Well you can actually go into the BIOS and overclock your machine, but I would not recommend it. Unless you know exactly what you're doing, and understand how the hardware works with Voltage, Heat temperatue etc, then it's not an option to do so.

Normally when you upgrade to a supported RAM type, the motherboard automatically detects what kind of RAM you've installed, there should be no reason, in the majority of cases, to alter the BIOS.


If the two machines have identical motherboards, then it shouldn't be a problem for you to upgrade Machine 2's RAM to 4x1024. As long as it's a supported type. ('SDRAM' , 'DDR SDRAM', DDR2 , DDR3 )

If you don't know how to determine what kind of RAM you've got already, then I can recommend this little program called CPU-Z. DOWNLOAD LINK

I hope this helped you a little further.

These are your options if you want to upgrade the CPU but you are limited to the 1333MHz FSB by the systemboard.

Click the button "Scan my System"

It'll tell you what memory you can buy that's compatible with the system, and sell it to you at a reasonable cost.

Look at a stick of memory from system 1.  If they match a memory type that's supported for system 2, you might be able to move the memory from system 1 to system 2, and then buy new memory for system 1.
