post #1 of 15
Thread Starter 
Which would be a better setup,

running 3x2gb at 1200mhz 6-6-6-18
or running 2x2gb at 1600mhz 7-7-7-20

For your AMD? Definitely the 2x2. AMD does not support triple channel memory.

GB size has nothing to do with it. MHz does. Always go for more MHz. As timings will have to increase with the MHz anyway. As you realized in the OP.

Not really true, AMDs tend to benefit more from tighter timings than higher frequencies; of course there is a sweet spot though.

Letsget, you shouldn't always go for more Mhz, on an AMD setup, especially one clocked at 4.4ghz, timings are more important then anything. But pair timings with high speed, and that's bliss.

That's why I think im just going to take on of my sticks out.

Also you can have 3 sticks of ram and still be dual channel...

Definately 2x2 for your current setup.

Yes I know that "fact" as I've owned AMD CPUs for the last 12 years. And still do own a Phenom II 965 DDR2 rig. See a old screen shot below. But even though, I'd go with the higher MHz, test it, then go with the 1200 6-6-6 settings and test it again to see which is better/faster in your case. I'd say the 1600 7-7-7 wins out. Myself (because I'm AMD inbred) I like tighter timings in both processors, so I only go as high as my 7-8-7 will take me stably, rather then go to 8-8-7 or 8-8-8 @1800+. But I do have a set of 2000 8-8-8-23 Super Talents coming that I'm hoping will get me to 1600 6-6-6-19. The very best of both worlds. (unless I can squeeze a 5 in there)
Oh, and yes take out that 3rd stick.

3X2gb will just end up being slower because AMD doesn't support tri channel go for the 2x2gb.

You could always put your controller into 'ganged' mode, which will negate any "LOLOL UNBALANCED RAM = SINGLE CHANNEL" misinformed comments.

It really depends on your use.
4 GB should typically be enough unless you're at >85% utilization.
