Not getting rated RAM speeds

Hello everyone. Just joined cause I bought new faster RAM which I was under the impression my mobo supported but now installed I'm not seeing that speed.

I have an Acer Aspire 6920G laptop. The board is listed as Aspire 6920 from cpuz. On the Acer website, and crucial, newegg, and more, it says that this machine is compatible with DDR2-667 and DDR2-800 RAM with a max of 2GB per stick. Well it came with 667 and I just bought two 800s.

From cpuz, I've learned that the FSB of my board was 200 x 4 = 800 Mhz. So I thought to myself, wouldn't it be better to get RAM that was more in line with that frequency. My old divider was 3:5 and I was hoping to achieve a 1:2 or 1:1.

But I've just installed the new DDR2-800 RAM and nothing seems to have changed in cpuz. the DRAM frequency is still 333 not 400 and the FSB;DRAM is still 3:5

I thought, maybe I had to go into the bios and set this manually, but there is no such setting even close to this type of thing. I have like 5 options to set in the bios: boot order, password, and a few others.

So I feel I have two options right now. Get a new bios, which I've never done, or just accept the fact that my board was never able to handle this RAM even though it was advertised to be able to handle DDR2-800. But with a FSB of 800Mhz I don't see why it wouldn't be able to.

Any input, suggestions, advice, calming techniques will be highly appreciated. Thanks a bunch

I'd start by flashing it with the most current bios version.

Also note that ram speed will have almost no effect on how the computer performs so don't stress over it too much

I've never gone through that process of flashing the bios. I know it's a real risky thing to do. I'd like some kind of verification that if I do this, the newest bios that I'd get from Acer will give me this option of changing ram frequency and timings. I'm new to overclocking and for now I just want the clock to be where it's supposed to. nothing less. Then I'll start pushing buttons to get more bang out of it
