The Meaning of DDR3 "PC3-14900"

[relaks]

Hi there,

Do anyone of you know what "PC3-14900" means in a RAM module?

Thanks

It means its DDR3 1866 MHZ RAM. Its just a designation used by the DDR standard to easily categorize between DDR, DDR2 and DDR3 RAM and there different operating speeds.

DDR means Double Data Rate. So DDR is 2x 1866 = 3732 . DDR2 is then 2x3732=7464 and taht times 2 is then just over 14900.

PC3 means that the ram is DDR3, it is keyed to only fit in a ddr3 slot.

The 14900 indicates that it is 1866 speed ram.

Now I understand! Thanks guys

Another question, in gaming theory, which is the best: having a high bandwidth RAM or a low latency RAM?

High frequency(not really bandwidth) is better than lower latency.

But it very much depends on what platform you have. 1155-1156 sockets scal up to 1866MHz, so its pointless getting higher than that. AMD on the other hand can support higher.

What are your system specs???

I am still gathering information for my new build but so far the specs are:

• 
  i5-3570K (Planning to overclock)
  ASrock Extreme 4/6
  2GB XFX Radeon HD 7850 or 2GB ZOTAC GeForce GTX 650 Ti mit CUDA

Go with the ASROck Extreme 4, i have one and its great. Cheap too. Gives you more cash for a GPU...

The fastest RAM i can suggest for Z77 is 1866MHz, even 1600MHz is perfectly fine.
What monitor resolution do you use or want to use? What games?

Regarding the MOBO, I was reading that since the Extreme 4 is a little bit thinner than a standard ATX motherboard it may lack secure mounting on the far side and the motherboard may even flex. So right now I'm a little bit confused. As for the resolution, obviously I want it to be more than 1080p.

I have a huge HD7950 on my extreme4 and have no noticeble flexing.

About gaming at 1080p and above, you really need to spend more on a GPU to be able to play newer games. A GTX650ti or HD7850 won't cut it at that resolution.

Ic, thanks for the info mate 😉
