I've recently taken some old DDR2 800MHz RAM from another PC of mine and need to use it temporarily.
However, I have no idea what the timings are.

The RAM goes by this code: HYMP125U64CP8-S6 AB
There's some more writing on the sticker, which is: 2GB 2Rx8 PC2-6400U-666-12

I was wondering if it is 666-12 as that's the closest to a RAM timing.
I've been searching over the net and can't find anything.
Any help would be much appreciated!
