No yours needs DDR2, it does not support physically or from the cpu.
DDR3 needs Nehalem processors
You have to have FBDIMMs to fit your Risers
These are great and what I and others use -2x2GB FBDIMM DDR2 667MHz @ $35
Thanks Hatter, appreciate your reply.
That is a great price. As long as I buy a pair that meet Apple sepcs I assume it is OK to have a mixture of sizes and suppliers.
Presently I have 2 original 512 MB from Apple, 4 x 2GB from Trans Intl and 2 x 4 GB from Trans Intl. I want to switch out the smaller ones.
I Checked out the amazon RAM but they will not ship to Canada and amazon.ca does not have that RAM.
I will likely replace the 512s with 2x2GB from trans intl. they have worked well up to now and then I will have al from one supplier. . Yes, I noticed that the RAM in salts 1 and 2 was getting warm, 75 deg C and I bumped up the fan .
