ok basically i have a dell dimension 8100 (bought in summer 2001 in UK) and i want to get extra RAM for it. I checked out the dell website and they say for 8100 i should use Kingston KTD-DM800/512 512MB Kit . Now not only do i not need this much extra ram, its also really expensive, but on the dell website and the Kingston website this was the smallest amount offered for the 8100 series. So i looked around to see if i can maybe find 256mb ram which can also work on my dell, and i think i might have found some, but im not sure. Here are the specifications of the dell website recommended ram : Kingston (KTD-DM800/512) 512MB Kit Product Description Memory - 256 MB x 2 - RIMM 184-PIN - RDRAM Storage Capacity 256 MB x 2 Technology RDRAM (RAMBUS) Form Factor RIMM 184-PIN Bus Clock Rate 800 MHz and now here are the specs for the ram which i am thinking of buying instead : Kingston (KVR800X16/256) 256MB RIMM PC800 RDRAM Non-Parity Product Description Memory - 256 MB x 1 - RIMM 184-PIN - RDRAM Storage Capacity 256 MB x 1 Upgrade Type Industry standard Technology RDRAM (RAMBUS) Form Factor RIMM 184-PIN Bus Clock Rate 800 MHz Data Integrity Check Non-parity these specs seem similar but i dont really know a lot about ram so was just wondering if the 256 one would work on my system ? any help would be appreciated, thanx .
