Opening the package is still simple, but in the memory take out you can already get scared that the memory breaks through.
So be careful!
The memory runs at the Sony Vaio CR21S.
In the product description here CL5 is so indicated at 400MHz DDR2-800.
Unfortunately the Vaio makes only 333MHz (DDR2-667), but is still faster than the old store.
According to CPU-Z and Memtest86 + memory timing is set to 5-5-5-15.
The store itself has loudly SPD chip: 5-5-5-18 for 400 MHz.
The sticker can only 2GB DDR2-800 and decipher based on designations.
He I'm fine, even with the old store together operated satisfactorily.
It is also recommended for this price (26,99Eu).
Have a second ordered equal yet so are probably the 4GB max. for this laptop / notebook and reached my Win7 still works a little faster.
