My notebook already has a 4gb stick of ram that is SO-DIMM DDR3 PC3-12800 CL-11 1.35v

I purchased a stick of Corsair Vengeance 4gb SO-DIMM DDR3 PC3-12800 CL-9-9-9-24 1.5v.
Are these going to be compatible since they have different voltage and timings?

Notebook model: Sony vaio SVF14219SGB.

Hi Kong Eng
Mixing different brands , voltages and timings can be very problematic , we see so many cases here where this does not work
seeing as you have the ram , you can try , but do not be suprised if your notebook does not boot
I suggest getting exactly the same brand timings and voltages ( same model number ) when installing new ram

I would need the exact timing of the currently installed stick but honestly you would need to take it way over its rated voltage and the Vengeance stick would not be running at full performance.

If you even boot (flipping a coin) you would most likely not have the best stability.

As for damage I do not know what to say as it is a laptop and resetting the bios is not fun so i guess flip another coin.

Then I would probably get a similar stick with my original one. Anyway, these
are the timing of my original memory. Thanks :)

DRAM Frequency 798.7 Mhz
CL - 11
tRCD - 11
tRP - 11
tRAS - 28
CR - 2T

it would probably be better to match the vengance , being a newer ram
try that and if it works on its own , it would most likely be easier to get than an older ram
plus it has better timings with a cas latency of 9 and not cas11 like your original stick
