Do you mean "What does (oc) mean?"
(oc) means that the memory won't automatically run at that speed. You have to make changes is teh BIOS to make it do so.
As for any "automatic" overclocking (overclock genie), stay as far away from that as you can get! Automatic overclocking just uses settings that someone at the motherboard manufacturer thinks will overclock a typical motherboard with typical components. Their goal is to be able to automatically overclock the widest range of combinations that they can. The compromises necessary to do that result in using settings that in all likely hood are not the "best" settings for a particular combination.
It's like buying a "generic" shirt site unseen and only knowing it's a style and color most will like and it's a size that will fit most people. What do you think your chance is for getting a shirt that's good for you?
A little info about memory speeds and latency:
Latency is the number of computer "clock ticks" that the memory takes to complete what it has to do. Since each clock tick is a specific, finite length of time, latency is really measures of time (in nano-seconds).
A rough mathematical representation for memory specified as 2000 MHz with a latency of 10 would be:
Speed 2000 MHz = 2, 000,000,000 clock ticks per second (2 billion per second)
A latency of 10 takes ten times a 2 billionth of a second to complete, or 20 billionths of a second.
But, no matter what "clock speed" the memory runs at at latency is always 20 billionth of a second.
So, if you speed up the clock ticks (overclock) each clock tick is shorter and it takes more of them to get to 20 billionth of a second. So at 3000 MHz that 2000 MHz memory takes 15 clock ticks instead of 10, so you would have to set (manually) a latency of 15 in the BIOS. Note that the above is all an approximation of the way "typical" memory would work. In practice the latency at 3000 MHz may be 14, 15, or 16, and memory and memory controller voltages may, or may not have to be adjusted upwards too.
Back to overclock genie:
If it "guesses" a latency of 16 and 14 would actually work, you're loosing performance (almost 15%), If it guesses 14 and 16 is actually needed then no boot.
I hope that helps.................Edited by billbartuska - 11/2/15 at 9:36pm
