What does this mean ?

post #1 of 4
Thread Starter 
I was looking at Asus M5A87 motherboard and i saw a memory support like this

DDR3 2000 (O.C) / 1600 (O.C) / 1333 / 1066

So i've been wondering what exactly does mean in brackets overclock next to memory ?
Does it support 1600 MHz or it has 1600 MHz only for overclocking ? (same goes to 2000)
Also i'm buying a memory with 1600 MHz so will this motherboard support it ?

Thanks

It means that to hit 1600 you need to use the fsb to oc it to 1600+.

The chipset officially supports up to 1333MHz. Running memory higher than that is supported by the MFG, but requires changing a couple simple settings in the BIOS to run them at higher-than-officially-supported speeds - but you shouldn't have any issues with this. Just read the manual with the motherboard and you'll be fine.

The BIOS should be able to set the x8 multiplier for 1600Mhzd operation, without bus clock overclock, as with every single socket AM3 and AM3+ motherboard (except lowest end boards for prebuilts). It is often undocumented or documented wrongly. There are no problems running 1600Mhz on all C3 and E0 revision processors.
