I put this in mobile aswell, sorry for double post, but I think you guys over here have more activity so I am more likely to be answered...

I have a PB laptop, it has an VIA MVP4 chipset but I am unsure of the mainboard manufacturer as it does not say anywhere. It has an AMD K6-2 450mhz (non +) With an external L2 cache, 512k external I beleive it is set to. Now, I have read somewhere that 'cacheable RAM' could be exceeded if I install too much, reducing performance. It came with 64mb, but I have increased it to 192mb becasue I want XP to run on it. Now, can anyone explain cachble RAM to me as I am unsure what it is and what impact it will have on my system. Thanks.
