My new build. RAM question

CPU: 1090t
GPU: 6850
MB: Crosshair Formula V
PSU: Some off brand p.o.s (Will be replacing it with the corsair AX1200)
RAM: Bulk ram.
SSD: Corsair F60
HDD: WD Caviar Black 1TB

Okay here is my question.
Do I want RAM that has a higher clock speed? I'm sure i'll eventually overclock.
Is there certain RAM that isn't compatible with AMD chipsets?
I'll eventually populate the board with 32GB of RAM when the 8gb sticks of ram are released.

What are you planning on doing with this build? For most purposes 4 gigs is fine, 8 gigs at the most. As for speed I'd say max 1600 is necessary. As long as its DDR3 you should be fine.

8 gigs should be more than enough for you then.

That's not really the point. Nor was it my question, but thanks for your help

well I just didn't want you wasting any money =p
As far as speeds go 1600 mhz ram can get you to OC your cpu to 4.0 fairly easily, much past that and you'll probably want 2000 mhz.

So the higher the clock speed essentially determines the cpu oc? I know you don't want to run your RAM at higher speeds then it's intended. I wouldn't oc my cpu much at all, 4.0 would be quite perfect.

Edit: I currently have 8gb. Perhaps you can enlighten me to what would actually require 32gb of ram, and you may actually save me some money.
2nd Edit: Actually, lets do this. Your budget is $300, you have a crosshair formula V, Choose your dream RAM (8gb) link it to me, and tell me why it would be the perfect choice. clock speed, latency, etc. I Know absolutely nothing about the technical bits of RAM and I love to learn. :)  So get down to the nitty gritty when explaining it.

response to first edit: 16 gigs would be overkill for 3D rendering, so idk where 32 would be be useful. You would notice a better performance increase from a better video card, if you really wanted to spend money on something.

2nd: G.SKILL Ripjaws X Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900)
this is only $175 and is 16 gigs btw

1866 mhz will give you plenty of room for overclocking

9 cas latency is probably the best you can find at 1866 mhz. "CAS (Column Address Strobe) latency (CL) is the delay time which elapses between the moment a memory controller tells the memory module to access a particular column in a selected row, and the moment the data from the given array location is available on the module's output pins."
The lower the better, you can probably try to lower that after you oc your cpu.

its only 1.5 V (some are 1.65) which gives more room for increasing voltages (again for overclocking)

Okay. I plan on upgrading in the following order.
Psu
Gpu (msi twin frozr iii 6950*2)
memory
I'm just set on the first two. Ram is more complicated (to me) and I wanted to be an educated buyer. And when you mention "lower the better" are you referi g to CAS?

Yes. Lower CAS means less delays between access/read. Generally the lower the cas, the lower the clock frequency is, however. The faster ram at lower cas latencies are fairly expensive, but are worth it if you're trying to max out your system.

Okay these are my options as far as RAM that's compatible with my mobo.

Model #:CMT6GX3M3A2000C8
Model #:F3-12800CL7D-8GBXH
Model #:CMZ8GX3M2A1866C9

Which would be best? i love the look of the first one. Second is okay.

My two cents is you can never have too much ram, just not enough. History has always shown that you will use it. In the old days people thought 48K was more than anyone would ever need and 64K was a waste of money.

The other thing is memory is cheap. So buy it now. I added DDR2 memory to one of my systems and had to pay double what I originally did because DDR2 has been going up since they don't make as much of it anymore.

Given the board that i have a lot of ram that is compatible at 8gb+ is ram i don't like. slow speeds, etc.

Sure it's cheap, but you won't need more than 16 gigs for a long, long time. And by then memory will probably be much cheaper so why overdo it now when you don't need it? When more than that becomes useful then just upgrade then, and save a little money.
