Re: googleearth RAM Cache

[Michael <codejodler@gmx.ch>]

Hi all,

Concerning the google 'flight control' helicopter-steering mode which suddenly got 'disruptive'.
After some tests, i'm still not clear how it works - but it's ok, now.
What finally made a difference, was trimming the RAM cache down to 600M. Google default is about 400, for 2G Ram, and i pushed it up to 1024 in the beginning because i though that would enhance things. I think i may have to accept that 2G of slow 333Mhz DDR2memory (though running in dual mode) just is not fast enough for the google aircraft. At least for high speed low-level flight through the Grand Canyon, and investigatin glacial gorges and volvanos in the Sierra Nevada ;) The same applies for ADSL2000 with slow uplink -- and then the googleearth server may have some load at times, too.

I always find it not easy to determine the exact RAM type just by the stickers on the bars.
They say 'Corsair Value Select VS1GB667D2' which seem to be the same. On each 64M chip there are cryptic numbers like '64M8CFEG  PS0900635'. 
So usually i trust BIOS wich in this case says 'DDRII667 (333MHz)'.

I would be interested can i tell by dmidecode what kind of RAM is installed ?

It looks like
