<<I learned that Windows 95 is not capable of utilizing more than 64mb of RAM. However, Windows NT would be able to use more than 64mb and supposedly windows98 will be able to. Not to sure why>> The 64 meg RAM limitation is actually a function of the chipset used on your motherboard, the broad statement that Win95 can't use more then 64 meg stems from the fact that the majority of Win95 computers have been based on the socket 7 motherboards of which the majority of these were produced with the TX chipset from Intel which can't cache more then 64 meg. You may still use more then 64 meg Ram on these computers but you will experience a 10% (as I recall) reduction of speed in the access of memory locations above the 64 meg limit and here is where the problem lies. Windows 95 loads high in memory, that is it goes into the last blocks of your RAM, if you have more then 64 meg then it resides in that area above the 64 meg cachable limit thus slowing down eveything you do, not good. The brite side is Windows 98 like Windows NT loads into the bottom area of RAM therefore you do not experience this slowdown in access to your basic operating system functions. Using RAM above 64 meg therefore on a TX chipset based motherboard may load applications and data etc. into that area above the 64 meg cacheable area but it is my belief even with the 10% slowdown in RAM access this would still be much faster then access to your virtual memory where these would otherwise end up being paged to. (virtual memory is your swapfile, Windows uses this as an extended RAM area and places it on your hard drive. Do a find files for Win386.swp to see the amount of virtual memory you are currently using, this will give you an idea of how much more RAM you might add to your system to see a very benificial speed increase. I would open up those apps you currently use concurently to see this. ) The Intel VX chipset does not suffer from this limitation as I recall and the chipsets from VIA and SIS may not have this limitation either. I do not believe any of the Slot 1 (Pentium II) chipsets suffer from this limitation either. Sounds like a good reason to upgrade to Win98? yep !
