Acer 5920G 800MHZ FSB/MEM how?

[taril]

Ive upgraded my notebook: 2x2GB 800MHZ DDR2
But The system information only shows 667Mhz FSB and 667Mhz memory speed.

How can I set it to 800Mhz?

If you have an Intel processor, you will never get 800MHz RAM. Some AMD notebooks might run it at 800MHz.

At this point I dont think there is a way to make your mem run at ddr2 800. The PLL on the 5920 is so far unsupported.

Santa Rosa doesn't support 800MHz DDR2, you can put them but it will be working with 667MHz.

OK. My Notebook CPU is T7300 (2.0Ghz, 800Mhz FSB, 4MB L2 cache)
what does 800mhz fsb means than?

from what i've been reading as a result of your post i'm being led to believe that the FSB of the CPU and the memory run on independent clock speeds especially when the FSB of the CPU is above 667mhz.

someone please correct me if that is incorrect...

FSB is the front side bus of the CPU
for example my 1.73mhz CPU

has a 533 mhz FSB which is actually 4 pipelines at 133mhz each

so thats 133mhz
and a X13 multiplier

which totals the 1.73..

just my 2 cents, for what it's worth,

My cpu's FSB is 800MHz!
I checked it with cpu-z, nvidia system monitor, clockgen. (200MHz)
So, it works on 800MHz, but how can i force my mem to work on 800mhz?
I can edit it with SPD tool. Anyone tried it?

Your cpu fsb must be 800Mhz, your memory cant run any higher than 667. With spdtool you can change your ram timings. For example i have changed 5-5-5-15 to 4-4-4-12

I have the same computer 5920G, with the default 2x1 gig ram that came with the notebook. I have downloaded the spdtool. How do I change the ram timings?

I bought 2 2gb 800mhz ddr2 sodimm.
why cant they run faster than 667?
