Questions about overclocking?

1. What are the consequences of having slightly too much voltage?

 

2. What are the consequences of having slightly too little voltage?

 

3. Apart from the number of volts necessary, does RAM use voltage any differently than CPU's to the point where I would approach overclocking them very differently?

 

4. Are artifacts on the screen (i.e. certain objects shaking slightly) an issue with CPU/RAM, or is it entirely a GPU issue?

too less/much voltage than what? What's the reference?

 

3. yes, because some DRAM overclock worse when voltage increases to a certain level, unlike CPU which can just go higher and higher until cooling isnt enough.

 

4. It could also be a dying cable. Unlikely to be related to CPU or RAM, since they usually causes freezes and blue screens.

1. death of the card/earlier death of the card 

2. lower temp, more unstable (sometimes)

3. haven't oc ram but I would expect similar results (youtube is a great resource)

4. can be all of them 

 

"May your frame rates be high and your temperatures low"

I misread titles/posts way too often--correct me if I don't.

what if i overclock my CPU/RAM, but give end up giving it a little less voltage than it ideally needs to perform at the clock speed I designate?

what if i overclock my CPU/RAM and I give it ample voltage, but I end up giving it a little bit more than needed?  Will the system freeze or crash?  Will it overheat at long workloads?

1. It crashes randomly.

 

2. Still stable, but increases heat output. Whether it overheats depends on the cooler and ambient temperature, just monitor the temperature sensors. Too high then it might cause damage.
