Nanya RAMs

[Guest]

Ok, here's a tricky question:

I have Nanya laptop RAM module with the sticker on them, which has the partial number: "NT2GT64U8HD0BN-AD"
Referring to this numbering guide: www.nanya.com/NanyaAdmin/GetFiles.ashx?ID=351
I have DDR2 SDRAM (T = DDR2 SDRAM), and I operate at 1.8V (U=SSTL-18).
But the last two symbols are "AD" which stand for PC3-6400-6-6-6 (DDR3 SDRAM).
So the question is: Do I have ddr3 or ddr2? And if I have ddr3 why do I operate at 1.8 Volts?

I have also checked the component number which is: "NT5TU128M8DE-AD" and does not match my understanding either.

You can download and install CPU-Z. this will also tell you what ram is installed.

Yes, but don't you think it's strange that the partial number has those mismaches...

Well when looking at the data sheet from nanya, it is PC2-6400 DDR2.

Also you need to look at the 3rd indicator, which is NT2GT
Nt - Tecnology
2G - 2GB size
T -DDR2 SDRAM
