CPU-Z SPD INFORMATION

[IPW]

Hey folks,

Can anyone tell me me why I have three columns of JEDEC data on my CPU-Z SPD readout?

Thank you

Everybody has three columns of JEDEC data in their CPU-Z SPD readout. That's the data programmed into the SPD chip on memory sticks.

Thank you. BUT - why those specific three and what for?

 

[Leaps-from-Shadows]

They are there to give the user an idea of what timings the memory can run at when set to different speeds. And it's those specific three because that's what the manufacturer programmed into them.

Thanks. The first part of that is exactly what I needed to know.

For example, if you plugged in some DDR2, you should see DDR 533, 677, and 800 listed. There is no official DDR2-1066 spec so that wouldn't be in there. I don't have DDR3 in my x38 board, but I should soon be building my new i5 750 rig next weekend. DDR3 should be 1066, 1333, and 1600. I'm not sure if there is any official spec faster then 1600 yet.
