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.

Im planning on getting the FX-8350, not intel cpus.

It's kind of the same thing though: the motherboard is extending the support beyond what the CPU natively supports. That means if you install DDR3-1600 or faster, then you have to manually set it because it will probably default to DDR3-1333.

Ok, so, how do you crank the memory speed? Do you still have to play with the bus speed, or fsb as it was called before?

And if i play with the cpu multiplier, will it affect ram speed like my current rig?

I am not a big AMD guy, but I believe it still applies, amd cpus memory controller is still just the same as intels, and I believe 1333mhz is just the standard memory controller speed.

I could be wrong here, but I don't think I am.

Either way, dont worry, it's not like 1600mhz wont work, you can do much more than that on either platform.

yes very good ram. however, if i were you i would consider the gigabyte 970a-ud3 instead of the 970 extreme3. thats just my recommendation. and yes these people are right, usually 1600 is something you set as a ram ratio inside the bios of the motherboard. my motherboard considers 1600 standard fair and doesnt consider it an overclock. most cpus when speaking of ddr3 support natively support ddr3-1333 and consider other settings overclocking, but as far as i know both bulldozer and piledriver can easily support speeds of up to 2000 without an actual front side bus overclock. my fx 8350 runs my ddr3-1866 at their advertised speeds without any sweat at all.
