Why is my 1066 ram running at 400?

[smeeon]

Okay here's the story..

I just recently finished my build after much debating and reading of the forums here I took advantage of the march AMDness at NewEgg and purchased an
Asus M4A79 Deluxe motherboard
AMD Phenom 2 x4 black 3.0ghz
Asus Silent Knight 2 copper CPU Cooler
4 gigs of OCZ pc2 8500 1066 2gig sticks
BFG Geforce GTX 285 which is slightly factory OCed

now with the Turbo V software that came with the motherboard I can overclock the CPU to a stable 3.5ghz which is fine for me.
however in the AMD Overdrive software it shows my ram frequency at 401.24 mhz shouldn't that be reading higher?

is there somewhere in the bios that needs to be set to be 1066? I figured Auto would do it.

also if I find i run stable at CPU frequency of 3.5ghz should I just set it that way in the bios and forget the software?

Thanks guys for all the help you've already given me, this community rocks!

400 means your RAM is running at DDR2 800. If you want to run at 1066 you'll need to manually set the speed as well as voltage and timings in the BIOS. OCing should be done in the BIOS.

Auto won't work simply because 1066 is not a jedec certified standard. While hardware support it, it has to be set manually. 1066 is only the ddr value, not the actual speed. just like 800. since 800 is 400MHz, 1066 will be 533.

yay its now 533, and very stable, thank you!

should i worry about OCing FSB/PCIe etc for gaming?will i notice a performance increase?

Don't change the PCIe. You will notice a difference if you OC by a significant amount, but it's not necessary if you're happy with your performance.

You should set the memory to 1067Mhz in your BIOS. If you want to start overclocking read the latest story on overclocking the Phenom II : http://www.tomshardware.com/reviews/phenom-ii-overclock,2267.html

You will see how simple it is to do by just raising the CPU muliplyer.

Yes I set the memory to 1067, which shows the clock speed of 533mhz in the OS, definatly noticed a performance increase.

and after some reading I had good and simple results changing the clock multiplier to 16x. Thanks guys !
