Crucial vs Crucial and a few other questions

[bh33]

I'm looking to build a new system and wanted to know which would be better for overclocking

Crucial Ballistix PC2-8500 DDR2 2GB 2X1GB DDR2-1066 CL5-5-5-15 240PIN DIMM Dual Channel Memory Kit
or
Crucial Ballistix PC2-6400 2GB 2X1GB DDR2-800 CL4-4-4-12 240PIN Dual Channel Memory Kit

I was going to buy the Corsair Dominator 8500 but its a lot more expensive than these Crucial sticks. Here is what my system will look like:

EVGA 780i SLI
Intel Q6600
EVGA 8800 GTS 512 crysis edition x2 SLI
OCZ GamerXtreme 700W
4 hard drives
Thermalright ULTRA-120 Extreme 6 Heatpipe Cooler LGA775 Heatsink
Scythe S-Flex 120mm fan for CPU and 4 other case fans
DVD Writer

So I have 3 questions
1. What RAM will work better for OCing?
2. Does the 8500 RAM work better then the 6400RAM or do the timings mean more c4 to c5?
3. if I get any of these can I get 2x2GB for 4GB or should I only get 2x1GB so less stress on the memory controler?

On a side note I came across this http://www.evga.com/support/mbmem/ and don't see the Crucial Ballistix PC2-8500 DDR2 2GB 2X1GB DDR2-1066 CL5-5-5-15 240PIN DIMM Dual Channel Memory Kit listed, anyone else have a 780i board and use these?

Thanks!

The top pair, but seriously, only 2 GB on a high end system like that is kinda a joke...

Agreed I was really hoping to go 4GB since memory is so cheap I just wanted to see if i would have problems overclocking with 4x1GB or 2x2GB of memory

It is better to go with 2x2GB, if you want to overclock 4GB. All rams using powerchip IC's for 4GB overclock well.

2GB is more than enough for most people at this point. 4GB is oftentimes overkill especially in windows xp.

bh, remember that because of the FSB bottleneck, you don't get very much performance improvement (sometimes even a decrease) by running the memory bus faster than the FSB. A 400MHz FSB (1600MHz datarate) corresponds to a 3.6GHz speed on the Q6600, but only really requires memory running at DDR2-800 (in dual-channel mode). Both RAMs you list should run fine at DDR2-800 at CL4.

Now who in the world wants to be running XP these days

heh...people who want low mem usage...! or is waiting for SP1 (SP1 refresh got released today for the public!) like me.

LOL @ waiting for SP1.

Those of you waiting are gaining nothing by waiting.
I said this months before, but SP1 does not change much at all in terms of functionality or compatibility with things from a user point of view.

If you didn't like Vista before SP1, SP1 isn't going to change your mind.
