AsRock P67 Extreme 4 Memory

post #1 of 14
Thread Starter 
I am building a PC with an i7 2600k, AsRock P67 Extreme 4, in the Dragon Rider case by In Win. I am wanting 16Gb of ram. I notice the specs for this motherboard are stated as such:

DDR3 2133(OC)/1866(OC)/1600/1333/1066


I am planning on overclocking my CPU to about 4Ghz (from 3.4 stock). I may go a bit higher after I feel comfortable doing so. My question, is what would be a really good recommendation for the ram I should buy? As stated, I want 16Gb in the long run, but I would be ok with just 8Gb starting out (the other 8Gb down the road should be cheaper too. However, I notice manufacturers such as Gskill make the notion it is unwise to purchase 2 8Gb kits instead of 1 16Gb kit....something to do with "possible incompatibility". What is the truth to this? If it is ok for me to get 2 4Gb sticks right now, an dlater add 2 more of the exact same stick, which is a good selection?

Why do you need 16GB's of RAM?

8GB's is much more than enough. 4GB's is sufficient for most people's purposes as well.
I would pick up some Supertalent 2000mhz cl8 ram here on the forums.

Why is it always about "needing" it? I stated that I would like it in the long run. Right now I am going to see how 8Gb suites my needs. I'd rather have 2 sticks of 4Gb than 4 sticks of 2Gb. How does that answer any of my questions? Just so you know, I plan on using this rig to run a virtual machine within Virtualbox; I plan on allocating 4Gb to the virtual machine itself. I've never had DDR3 memory; 8Gb of it may be way more than I need. But I want the ability to upgrade to 16Gb later if I want.

So, to ask my questions again:

1) Is it safe to buy 8Gb now and then another 8Gb of the same stuff later vs. buying a 16Gb kit now?

2) What ram is recommended at the fastest speed the above motherboard supports?

Well, it's important that we know why you actually NEED 16GB's of ram so we can help you pick out the right pair.... I would recommend CL7 1600mhz sticks.

If you buy the exact pair twice, then yes you can buy 2 kits.
At native it supports 1600mhz, while overclocked it says to support 2133mhz. I would say you could probably take it to 2250mhz without much trouble.

Well...I'm not sure I need it at all. I may honestly never take full advantage of it. But I plan on doing lots of audio/video encoding/transcoding/etc. Also, virtual machine are in my mind right now. Some gaming I may get into.

My biggest question right now is this:

When buying, should I buy memory that is rated at 1600Mhz or 2133Mhz? I notice the specs above say 2133 OC'd.

It truly depends on the timings. It's not completely necessary to buy ram just because it's rated at 2133mhz. Just look at RAM in your price range and bite the bullet. I wouldn't go lower than 1600mhz with CL7 for your purposes. Also, make sure to keep the voltage low! Don't go above 1.65v for SB.

Well this is my first build, and although I am quite experienced in the computer field, I have NEVER overclocked anything but my Motorola Droid 1 (which I found worked. I have indeed read about not going over a certain voltage on your memory when using SB, didn't know it was around 1.65v. I do not really understand anything about the "timings".

However, I think the message I'm getting is "just because something is not rated at 2133Mhz does not mean it won't run at 2133Mhz. But, 2133Mhz rated memory will run at that speed for sure, with stability. It is possible to buy memory rated at 1600Mhz and run it at 2133Mhz, with research, cooling, and care. I suppose it is related to bridges being rated at a certain weight limit for liability purposes, but in reality they can hold much more than that most of the time.

EDIT: I also just figured out what you mean by CL7. Up to this point I had no idea what Cas Latency was. I'm beggining to realize although I may be able to get my way around OS's, I do not know as much about hardware as I presumed. From this point on, when you refer to technical details, can you spell them out a bit more? At first I thought when you recommended CL7 at 1600Mhz, you were referring to a specific make and model.

EDIT2: Would it be best to buy memory rated at 2133Mhz CL9 or memory rated at 1600Mhz CL7? On Newegg the prices are as follows:

(G.Skill)
CL7 1600Mhz 8Gb 1.6V 149.99

CL9 2133Mhz 8Gb 1.6V 199.99

It's your choice what memory you want to get. I'm just saying that I personally would recommend CL7 1600mhz memory. You could save a lot of money and still have very good performance. It won't make a big difference except in benchmarks between CL9 2133 and CL7 1600 memory.

EDIT: In response to your edit,

My apologies. You learn something new every day. ;]

Where would you recommend purchasing this memory from? I like Newegg pretty well, but they do charge sales tax in my state Been trying to find some on Amazon, but it seems for the most part a lot of it is the lower speed stuff. Considered Ebay, because I have a $15 gift certificate for them, but I am a bit weary about buying high end computer parts on Ebay for some reason. Is Newegg my best bet?
