Since, people kept telling me to stay with 800 and not go 1066...which RAM should I get?

   
Desktop Memory (x) > Capacity : 4GB (2 x 2GB) (x) > Speed : DDR2 800 (PC2 6400) (x)  (1-49 of 49 Results)

Leaning toward: http://www.newegg.com/Product/Prod [...] 6820227267
OCZ Reaper HPC Edition 4GB (2 x 2GB) - $80
Cas Latency    4
Timing    4-4-4-15
Voltage    2.1V

Also, I think I will OC the Q6600 to 3.0-3.2...and I won't need to OC the ram...right? I just want a safe OC on air...I hear some do 3.2-3.6....but I rather be safe...3.0 is a good number or 3.2?

And is there a point in buying 1066 RAM is I don't plan to OC CPU that much? I mean...is there any other advantage to having a 1066 vs 800 RAM besides CPU OC?

800mhz RAM will give you a 3.6ghz overclock of your Q6600 without touching the ram.
 
The OCZ looks good , low CAS is good

k thanks.

no need to go 1066.  I have a similar 3.2 oc on my q6600, i bumped the multiplier down to 8, set the fsb to 400.  Now i'm running 3.2, and my ram is going at the rated 800.  good speed, good heat control.  life is good.

One more for DDR2-800 on the Q6600.
 
If you were getting an Q9300 or Q9450, then you would possibly want to look at ram that was certified to run faster.

Indeed 800 is the way to go, plus the 35 boards dont seem to like 1066 too much. Honestly though you are not going to see the diffrence between the 2, you could benchmark it, but thats where it will stop.
