This is my MoBo: http://www.newegg.com/Product/Produ... I was under the impression it said that it supports the DDR2 1066 as stated under Specs. This is the Memory I put in there(x2): http://www.ocztechnology.com/produc... It replaced the DDR2 667 (1GB x2) I had in there. In the Bios it registers x2 1066. I noticed the issue when Windows took many times longer to boot than when the 667 was in there. Than I noticed it when the reaction speed of everything took a hit. I ran PCWizard 2k8 and it seems to me like it is saying that I still have 667 in there though it is registering the new Type of Memory.

Ok so I just found some read that explained, what I posted above is probably the SPD (this is hard written into the chip and I need to find the live speed). I ran CPU-Z and it reports a Live speed of 533.4MHz which I am sure I multiply by DDR2 to equal a Live speed of 1066. Why then, do I have such a horrid boot time now and realy sad reaction times, for example loading web pages?

What FSB speed does your CPU run at? A 1066MHz FSB CPU should be paired up with DDR2-533, a 1333MHz FSB CPU should be paired up with DDR2-667. That way, the CPU & RAM are running in sync (1:1 ratio). If you use higher rated RAM such as DDR2-800 or DDR2-1066, it should be underclocked to maintain the 1:1 ratio.

Remember that Intel "quad-pumps" the FSB, so 1333MHz FSB actually runs at 333MHz. DDR2-667 RAM also runs at 333MHz. They're a perfect match! There was absolutely no reason to switch over from DDR2-667 to DDR2-1066 unless you plan on overclocking. And if you don't plan on overclocking, you should underclock the DDR2-1066 to DDR2-667 speed to match the CPU FSB.

Awesome reply : ) I figured installing the highest rated memory that the board can handle was the best way to go but I did not figure that it was hindered by the CPU : ( So with my current CPU I can not take advantage of anything above the 667? Also, would there be any advantage to using the 1066 underclocked to 667? One day I may find time to do some research on my boards bios so that I can actualy understand the slew of Tweaking/Overclocking options that they have included >.<
