Hey guys,

I just ordered the cheapest of the Limited Availability Specials that Alex posted a few days back. 

While looking at the nVidia site, I saw that this board only support memory bus speeds of up to 800 Mhz.  The RAM that they packaged with this board was the OCZ DDR2 1066.  It it also overclocked along with the Quad 2.66 processor and the video card. 

My only question is, was this a waste, since the board can't even "process" that RAM bus speed, especially with the OC?  I am not a very hardware-knowledgeable person, so I was curious.  If so, no hard feelings, but I might try to change the RAM order before they ship.

Official memory speed support does not mean that is the highest actual speed the board can support, it's simply the highest the manufacturer will garantee. Same with the 680i I have. I have seen some people able to get over 800MHz with all 4 DIMMs populated even though "officially" the board "can't" do that. RAM overclocking can also refer to timings. By reducing the delays (those numbers you see listed under RAM timings are the number of clock cycles the RAM has to wait before it can be accessed and written to or read from again), you can increase the effective bandwidth of the memory module just as you can by pushing higher MHz. Higher binned RAM is normally capable of tighter timings, which is a RAM overclock. Even if the motherboard does limit the RAM to a speed of 800MHz, that 1066 RAM may still be able to run much faster than other "800MHz" RAM can by virtue of these timings.
 
If the CPU is OC'd, definitely leave the higher quality RAM in there. Your Final OC result may depend on it.Wink

Thank you very much, Tyler.  Just wanted to make sure I wasn't paying for something that was useless or completely unnecessary.

Can't wait until my PC is shipped! Big%20smile
