Acer 5920G 800MHZ FSB/MEM how?

Memory speed doesn’t depend from cpu. It is limited by chipset.

The chipset that is in your laptop cannot run memory at 800MHz. Only 667MHz and lower.

RAM and CPU speeds are not always identical.

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?

1) Use Spdtool (to change cas 5 to cas 4)
----------------

Change this for every dimm:





after that, click 'fix chechsum' and save



2) Use Memset 3.5 beta to change the other timings

Thanks, the picture is not loading very well. I will try it but this looks quite dangerous, is it possible to easily revert it back if it make my system less stable or does it brick my laptop? Can you actually measure the speed gain after changing the timing? Right now the ram is the bottle neck in my computer with vista score 4.8. I hope I can increase the score.

For the begging do it for your (only) first dimm, check if everything works fine and then do it for the second dimm.

To measure the gaining speed, chech the latency with eg Everest Ultimate.

I have vista sp1, my memory score was 5.1
With timing changes my score is about 5.3

Post yours timing pleace!

I can't change my cas, after changing values to 4 and fixing check sum I am trying to write new values first to module 0 and then I get an error as shown on capured screen. I tried to ignore it but then I get 2 another errors and messege about compliting process but nothing is changed. Could someone tell me what I do wrong??

I don't think there is any benefit in running at 800mhz the memory module because (I assume) the memory runs in dual-channel which means that the frequency is doubled when using two modules.
i.e.: 2*667 = 1334mhz
Your system won't bottle neck this way as the memory runs at greater than or equals to the CPU fsb.

I followed cxmgp's instruction and got the same error result as Shamtu. The memory spd didnt appeared to change. Anyone help out?
