I have a Laptop ( toshiba satellite 4030cdt) with just the std 64mb ram in it. It is expandable by fitting a 128MB pc 100 ( strange as its 66mhz apparently) module in the expansion slot. It runs win 98.

So to the problem
Yesterday I was using it to tune the car using tuner studio. It does not seem to be up to the job.
When a second window opens on top of the first all of the graphics are not there initially. it takes a minute ( seconds that is but quite a few) to refresh all of the information. It is also latchy in updating the m/s itself which can result in you not knowing if/when the changes have been made. At one point yesterday during a burn to the unit it froze and the injectors themselves were held open for quite sometime (you could see the fuel spraying out of the trumpets FFS

so the question is really will the extra ram do the trick or am I wasting my time/money.
Thanks in advance folks

Have you done this?

"So, if you are running a laptop of less than 800 MHz it is suggested that you un-check the Antialiasing setting on the Menu:
Options --> GaugeCluster --> "AntiAliasing Enabled"
Gauges will not appear as smooth, the edges will be a little boxy like in MegaTune, but your refresh rate should be 2-4 or more times faster depending on Hardware. "

but it's probably chunterring because it's fragging the hard disc so yes extra RAM should help (as might closing everything unecessary beforehand).

No Ben I have not tried this Thanks for the heads up.
I was scared that I might have needed more graphics memory or suchlike.

make sure you clean the laptop up give it a defrag, close down any background programmes that will be using needed memory.
