Okay, theres probably a better place to put this, but off topic works.
I have a neon 500w power supply, on the back is the standard on/off switch, the fan speed dial, and something else.
It's a red switch that has the number 512 on one part and 115 on the other, it's always been set to 115.
What is it? What does it do?
The other is, , I had alway though DDR3 was superior to DDR2 SRDRAM, yet despite both being old RAM types DDR2 is much more popular, why? was I wrong.
