Dear all,

I've just bought 2 brand new 4GB ram module for my DELL Precision M6400.

I checked the Corsair website for compatibility before choosing and foud out this part number would fit my needs: CMSO8GX3M2A1333C9 (2x4GB module DDR3 sodimm).

They shipped today and I tried to install them in slot c and d, following dell manual instructions.

Once finished I powered on my laptop BUT: caps lock led started to blink and no bios started up.

I tried to remove the two modules several times, installing one at a time...same result!

On the manual it is reported that caps lock blinking = memory compatibility

Is that true? Do I have to blame Corsair for wrong information?

Thanks in advance for your kind reply
