Hey guys,

My desktop is about 5-6 years old I think, and I am finding that often it is slowing down.  I plan to get a new PC next year, but in the mean time I was looking at just getting more RAM for it.  At the moment it has 2x512mB sticks in it.  I want to probably put 2x1GB sticks in it.  However, I would like to know:


  1. How can I tell what ram it will take and what it wont?

  2. How many Mhz can it take (at the moment it has, I think, 400mhz?  Not sure)?

  3. How much you think it will probably cost (I can search for prices once I know what to look for though)?

  4. Can I simply physicaly remove the old ones and insert new ones, or will I need to instal new software?

Obviously you will need more info, not really sure what would be useful so please let me know (and how to get it!).

Cheers!

Download and install and run, cpu-z. It will tell you what you need to know as far as type/speed of ram, motherbaord make/model (so you can determine limit), and if you have any free slows.

If you think you have DDR400, then that will be your limit.
It is around $70 per 1GB stick of Kingston ValueRam.
If you have four slots, I would just buy one stick, and manage with that. IE, 512x2 + 1GB = 2GB. As the ram will not be able to be used in any new machine you get in the future.

Thanks for the quick response.

I have run the program and it looks like I have 4 slots (could verify by opening box up).  It is actually DDR200 at the moment, can't find on google anywhere what max Mhz it takes...

Anyway, here is what cpu-z says:

It's DDR400 (bus speed 200 = Double Data Rate 400)I don't see anything that says 4 slots there are MB with the identified components that have only 2 slots. You could always say what the box is :)

So thats what DDR stands for....

Anyway, I just assumed that by giving a drop down box for 4 slots there was 4 slots. After checking, it apears it has only 2.

Computer was custom-built by Quay Computers in Wellington, so not an off the shelf setup.

Oh, it has just occured to me that this is not the original motherboad: that fried and was replaced 2-3 years after it was purchased. Therefore the RAM is older than the motherboard (if it makes a difference).

So unless one of the other (different) empty slots can be used for ram I would have to replace a 512mb stick. Looking on PriceSpy, and assuming I stick to 'PC3200' because thats whats in their, would I want:

1GB PC3200 PC3300 DDR400 SDRAM $49.70
or
1GB PC3200 DDR400 ECC SDRAM $136.37

Where I have no idea what the ECC means. I would not bother if I need the expensive one, but for $49.70 I would replace at least one...

Cheers guys for all your help

ECC basically has extra error correction features and is only normally used in servers, just go with standard.
