DDR3 1600 memory support

[rishiswaz]

My motherboard supports 1600 memory but it has "(O.C.)" next to it and the lowest without the "(O.C.)" is 1333. Does that mean I have to overclock 1333 memory to get it to 1600 speeds or will it recognize the RAM but I will have to manually set the RAM speeds? Thanks

It means that you can install 1600 speed ram and oc from bios to get that speed.

So if i install it just as-is it would register it but it would only be like as it was 1333, and to get the full 1600 I would have to oc it

There are few possibilities as to what '(OC)' means, so what MOBO and CPU?

Your CPU-z is for a Lenovo Notebook, OEM BIOS e.g. HP, Dell (most), GW, Lenovo, etc will NOT allow you the mofify the DRAM Frequency beyond the CPU and/or Chipset Rated/Allowable Defaults.

Oh that is my laptop, I have all of the parts of my desktop in except the RAM which I am planning on getting from the store, in person. The ASUS motherboard supports up to 1866 (OC) I think it might go higher but I would not plan on experimenting that high anyways.
I dont remember the specific motherboard but I know it is an AMD FX-4170 CPU

The FX on AM3+ MOBO's is easy breezy with DDR3-1600 or DDR-1866, the (OC) applies to non-FX AMD CPU's. DDR3-1866 is native frequency for all of the FX (Bulldozer) CPUs. The Default Frequency all depends on the 'SPD' encoded on the RAM, it will Default up to DDR3-1866 IF there's a JEDEC that offers that frequency (not including XMP which is Intel).

You might need to manually set the RAM in the BIOS: DRAM Frequency -> DDR3-1600, CAS Timings (CAS-TRCD-TRP-TRAS-CommandRate) 9-9-9-24-2T, and the DRAM Voltage if not 1.50v.
