DDR3 1866 to 2133 OC?

[YuiD]

Hi all.

mobo: msi a68hm-e33 v2
cpu: a8-5600k


I understand that my APU Supported memory is DDR3-1866 based on its specs and also my motherboard supports: DDR3 1333/1600/1866/2133*(*OC)

Now my question is,

I'm planning to buy GSkill RipjawsX 16GB (8GBX2) DDR3 2133 /F3-2133C10D-16GXM, will this work with my apu and mobo?

Will I be able to OC it to 2133?

2nd question,

With these Avexir AVD3U16001008G-2CIG DDR3-1600 16GB (2x8GB) Green LED

* Manufacturers part code: AVD3U16000904G-2CIG.
* System platform type: Desktop.
* Memory type & speed: DDR3-1600 (PC3-12800).
* Capacity: 16Gb (2x 8Gb).
* CAS latency: 10-10-10-24.
* Test voltage: 1.5v.
* Registered or Unbuffered: Unbuffered.
* Error checking: Non-ECC.

Can i OC it to 1866?



thanks!

Personally I wouldn't worry about OCing the RAM. If you can get 1600 or 1866 with a CAS 9 you shouldn't have a worry in the world. CAS 10 isn't bad but the lower the better and 9 is sort of a good target to take aim at for gaming. Otherwise, things would usually run as fast as the weakest part allows.

Dont mix different speeds. Using an APU you want as fast memory as possible, so the GSkill 2133 will be much better.

I see. thanks for your replies.

How about using these:"
http://pcworx.ph/home/catalog/product/Memory/Memory%20Desktop/MEMPANPUD32400C114G2

Part No : PUD32400C114G2LSK / PUD32400C118G2LSK
Module Type : 240 Pin Unbuffered DIMM, Non ECC
Speed : DDR3-2400 MHz (PC3-19200)
Capacity : 8GB(4GBx2) / 16GB(8GBx2)
Latency : CL11-13-13-35
Voltage : 1.65v

2400 is way beyond the speed my system can handle though.

If I use this ddr3 2400 ram:
1 will it work with my system?
2 Will it default to 1866 or 2133 based on the highest speed my system can use? Or do i have to manually set it to 2133 in bios using amd AMP or my mobo's automatic settings for ram?

thanks!
