Sorry I haven't been on of late...been busy with other things.
On the computer I used to have that took a dump on me, I used to have a program that would give me detailed information on my system so I could more easily get upgrades for it.
My current DELL has the following for RAM: 1GB (2 x 512MB) Dual Channel DDR2 SDRAM at 667MHz- 2DIMMs
This system I have can be upgraded to 2GB, but I'm not sure of the PC???? amount, or if that information is even necessary. I plan to buy the 2 X 1024 sticks. The link below is to one of my options for an upgrade that I hope is compatible:
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2341730&CatId=2366
Or is this a possibility...its faster speed and half the price...not sure if it would be compatible because its 800 instead of 667. If it will work, I'd rather get this one.
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2206874&CatId=2261
If I need to know what PC number it is, how would I find it? I'm sure that information is somewhere but I can't recall exactly where to look for it...outside of opening up the case.

Aside from opening your computer and looking at the ram for information, you could use something like CPU-Z from www.cpuid.com

You cant have 2 different speeds of RAM, theyd need to be the same so ud need 667

Usualy DDR2 motherboards can easely go up to 800 mhz (PC2 6400)
The move expensive one's support up to 1066 or even 1200 but thats usualy overkill for a normal comptuer.
I notice you intent to REPLACE your current 2x 512 by 2x 1024, so you don't need to worry about mhz diference and timing.
Just look what your motherboard inside your computer can handle, usualy this can be cound on the dell website. and look what you would like to spend.
I would recommend going 800 mhz if you mobo supports it and you can afford it.
Other than that, nothing to add.
In the unlikely case you intend to ADD the new modules (if you have 4 memory slots avalable) you need to either buy 667, best with the same or lower tRAS.
Or possible buy a 800mhz set, but you need to be carefull here. because if the CL and tRCD are diferent you may end up slowing your new memory down.
p.s. always put the slowest memory in the first/primary memory slot.

I opened up my case, and I have 4 slots...the two (white clipped) are filled with the 2 (black clipped) ones are empty. Guess I could just get 2 more 667 speed RAM. Just to clarify, how do I find out what the tRAS is on my current RAM? I'll keep looking through the PC Wizard to see if where it says this though.
Since I'm not TOO savvy in these things, thats what the PCWizard showed me on my RAM. The other DIMM shows identical info.

CAS Latency (tCL) : 3 clocks @200 MHz, 4 clocks @266 MHz, 5 clocks @333 MHz
RAS to CAS (tRCD) : 3 clocks @200 MHz, 4 clocks @266 MHz, 5 clocks @333 MHz
RAS Precharge (tRP) : 3 clocks @200 MHz, 4 clocks @266 MHz, 5 clocks @333 MHz

Min TRC : 12 clocks @200 MHz, 16 clocks @266 MHz, 20 clocks @333 MHz
Errr...I'm a dolt. This looks exactly like what I need.

What dell system do you have? Some of the low end models only have 2 memory banks... The med and upper range system have 3 or 4. If you have dual channel memory support then more than likely you have 2 or 4 slots.
Might be cheeper to buy matched memory for the empty slots if you have them. Open it up and look.
And you CAN have two different speed memories in a system, they just have to be in matched sets. And the slower memory needs to be in the first channel.
Sometimes the channels are side by side, sometimes they are split. Channel A - slots 1 and 3, Channel B - slots 2 and 4
You CANNOT mix ECC and Non-ECC memory.

My system is a Dual Core, AMD Athlon 64 x2 4000+ 2.1Ghz with 4 RAM slots (slots 1 & 2 are occupied w/ 3 & 4 empty) that I got back in May 2007 for 500ish green backs. I found a set of matching RAM at TigerDirect that is identical to what I already have. It just doesn't say anywhere if it is ECC or not, though probably not likely.
The PC Wizard shows the ECC Diagnostic to be No.
In the old 1.4 Athlon that took a crap on me, it had 256 non ECC RAM and needed more memory and I found ECC RAM on eBay (the only place that had it for a computer that was 3-4 years old) and it ran fine on it. Though my current CPU would probably have a coronary if I mixed them like that.

Whats your system Tag, its a 7 letter/number code either on a white sticker on the back on on the same sticker with your express service code... This tag will tell us your exact system and its specs as it was shipped out to you.
Or you can tell us the make and model...
Such as, Dimension 379, or Vertio 1530...
