Newsgroups: comp.sys.ibm.pc.hardware Subject: different speed memory chips Message-ID: <1991May31.213009.11861@ux1.cso.uiuc.edu> Date: 31 May 91 21:30:09 GMT Sender: usenet@ux1.cso.uiuc.edu (News) Organization: University of Illinois at Urbana Lines: 11 Hi, I have a 286 computer that has 640K RAM, and I would like to change it to 1M. However, I think the memory chips on my motherboard are 100ns ones and the new 256k DRAM chips I'm buying are 80ns. So, I'm wondering if there will be any problems if I use 18-100ns chips and 18-80ns chips to bring my machine's memory up to 1M. Thanks. -Ching -email ching-tai@uiuc.edu -OR ctt31684@uxa.cso.uiuc.edu
