-----Original Message----- From: Robert Zeoli <[log in to unmask]> Hi I have a 200meg pentium with 32 megs ram. The mother board is a 8500TVG Pentium VX System Board. I don't know who the mother board manufactuer is, the users manual is pretty generic. I just installed an additional 64 ( 2 - 32meg EDO pcs) megs of ram to a system with 32 megs ( 2 16meg EDO pcs ). I did move the original 32 to the other 2 open rows (bank 1) per the diagram on page 1-22 of the users manul for 96 megs of RAM. The new RAM went into bank 0. During boot the ram check goes okay till 70megs then the computer beeps three times. It stops checking the ram and continues the boot process. Under "My Computer" properties, it comes up as 70 megs of ram. Funny thing though when I go into the Bios as the booting sequence is checking the ram, it checks through to 96megs. Then My Computer properties shows 96 megs of ram. Is there somthing I need to change in the Bios to add RAM? I tried it with the RAM in the other slots 2-16's in bank 0 and the 2 32's in bank 1 but it then only shows 40megs. ---------end of original--------- I hope someone will correct me if I am wrong, but it was(is) my understanding that the VX chipset is limited to caching only the first 64 MB of RAM, and that installing more will actually provoke a performance hit. How well does your machine run if you simply put in the 2 32MB SIMMS? Another avenue to investigate, should the above not be the problem, is are the SIMMS all of the same type, and will the motherboard accommodate unequal amounts of RAM in the two banks. (I tried to configure a Supermicro superTX chipset m'board with a P233 MMX with 96 MB of RAM. It would have none of it, and I'm reasonably certain--after several exchanges of the 2 32 MB SIMMS I purchased--that the memory types were the same. I tried 2 32's in bank 0 with 2 16's in bank 1 and the reverse. Neither was stable. I went back to just 64 MB and the machine has been stable. I suspect I will have to add another 64 MB in order to increase my RAM and retain a stable machine.) HTH, Paul A.
