Upgrading Ram

[gslrider]

I have the 2.8 GHz, Mac Pro Xeon 8-Core. It came with 2GB of ram, and I added after market ram (Kingston PC2-6400 800Mhz DDR2 ECC buffered 2GB x 4), I have two slots left that I'd like to fill up with the same aftermarket ram. Unfortunately, this ram is apparently harder to come by now then the last time I picked them up at my local computer store. I'm wondering, does it have to be DDR2 or can I use DDR3 ram on my machine? And does it have to be ECC? Does ECC or non-ECC make a difference if I'm not using my system as a server? They ram I have in there now is ECC, can I mix in non-ECC with it?

Thanks.

If it is the DDR2 model no the DDR3 will not work. There are two 2.8Ghz Mac Pro, 2008 and 2010 models. Here are the specs from OWC of the former DDR2 modules:-

Thanks Nam. I have the 2008 model. Now does it really matter if the modules are ECC or non-ECC? From my understanding ECC ram is normally used for servers. Since I don't use my system as a server, is it ok to use non-ECC ram with the same specs?

I may be wrong on this but I think it doesn't matter as long as it's all ECC or all non-ECC

I just read up more on this matter. I think your right Analogue, but more importantly it has to be FBDIMMs. Those are the only ones that will fit in the slots for 2008 Mac Pro 8-cores. Guess I'll have to purchase these online.

Thanks for all the input.
