Choosing RAM

post #1 of 5
Thread Starter 
Hi everyone, first of all, i'd like to say that i'm spanish so sorry if my english sucks frown.gif ill try to be understanable.

This month i'm going to get a new PC that will be formed with:

Amd a10-5800k
Asrock fm2a75 pro4
RAM??

Here comes the problem, i was completely sure to get:
Kingston hyperX predator 2x4gb 2400 cl11
(why 2400? Becouse the apu needs at least 1866 but you get best performance with 2133 so what i found was the:
G.skill ares 1866 2x4gb

and my quetion is, i will be able to OC the ares ram further than 1866? Or that is they're top speed?

Thanks for reading this huge text biggrin.gif

waiting for some answers smile.gif

You might be able to clock them higher, but that is their highest guaranteed speed, so they will definitely get to that speed, but they may not go higher (unless your lucky).

Loosening timings and increasing DRAM Voltage can greatly improve OC

They should do 2000MHz with looser timings but AMD favors tight timings so 1600 cl7 is better then 1866 cl9 for instance

That board will run 2600 MHz DDR3. It's entirely up to you what you want to buy to put in it. Timings mean nothing when you're using a APU, go for the highest frequency memory if you're looking to do gaming on this APU. I personally wouldn't go over 2400 MHz with this APU as its memory controller was only designed to support 1866. Tho don't be afraid of buying 2133 MHz memory outright. If you plan on overclocking 1866 to that speed, you might as well just buy the memory already rated for that speed. As there is a very small price difference between the two. To answer your primary question tho, I wouldn't depend on 1866 memory reaching 2400 just by overclocking. You are better off just buying a 2400 MHz kit and setting the XMP profile in the bios. You can pick up a 8GB 2400 MHz kit for $70 anyhow, same price as 1866. It's your choice, if you're skeptical about which to buy just pick up a 2133 MHz kit. They run only one bump over the memory controllers native support, so they should run fine while offering a couple of extra frames per second in games.
