the voltages are the same... Ive not touched the overclock ive only changed the cooler. I did use a different version of cpuz just as I liked the skin better..
In your defense when I looked at them in the size there showing as you had me wondering for a second I thought the top one said 1.243 rather than the 1.248 that it is.
I had to open it to the bigger size for a look as you had me thinking there was a difference.
I think its with it being the black ROG theme its not as easy to read
