What 1600(oc) mean?

post #1 of 18
Thread Starter 
Hi, im thinking about buying a new rig and most if not all motherboard now have (oc) written beside supported ram speed. Im planning on buying those, but i don't know if they will work. That's the motherboard spec for the rams:

DDR3 2100(OC) / 1866(OC) / 1800(OC) / 1600(OC) / 1333 / 1066 / 800

Could someone explain this to me?

Also, should i get ram with higher frequency speed since they're pretty much the same price, or it dosen't worth it?

And one last question, would it worth it to get ram with 9 CAS lantency instead of 10 for a few bucks more.

Thx.

Pretty much all motherboards will say that, supporting 1333mhz and then OCing 2000mhz+.

Long story short, yes it will work, not actually sure why they always say oc for anything above 1333mhz.

Now that I think about it, its probably because all 1155 cpus have a 1333mhz memory controller and anything above that is considered overclocking, so it's more about the cpu and less about the mobo.

It means that if you have DDR3-1600 or higher, then you'll have to manually set the speed because it will likely default to DDR3-1333.  So the board is extending the speeds that are natively supported by the CPU.

DDR3 2100(OC) / 1866(OC) / 1800(OC) / 1600(OC) / 1333 / 1066 / 800. Mean you will need to oc the FSB to hit the speed of ram. Most Bios update will fix some of it too. What mobo do you have?
CAS 9 is a little better than CAS 10.

I've always found that it means you have to manually set the memory to these higher speeds because the board is extending the support beyond what the CPU natively supports.
