Re: [H] mem question
Hi Duncan, EDO dimms came in two versions, both 168Pin. You could have 3/3.3 volt, and 5 volt EDO dimms. Finding EDO dimms over 64MB can be hard, and over 128 MB without being registered ECC (both must be supported by the chipset). Most chipsets of that time could only address 64mbit chips, which resulted in a 64MB 8 chip dimm or 128MB 16 chip dimm. What chipset is on the board, and how many slots? Does it have both 72pin simm slots, and one or two dimm slots? Harry dhs wrote: OK so I have a really old machine. I'd like to think that it might be PC66 but now I'm not so sure. It is EDO ram. NOT SDRAM. Got some new DIMMS today, but they do not fit. They were/are SDRAM. At least they are based on where the notches in the DIMM(s) are. Have RMA needs and is in process (tomorrow). They were EDO by chip specs, though. Does anyone have pointers/links to when/what the JIDEC specs are for DIMMS? Looking for the spacing of the locating notches and/or socket specs for the 168-pin pwbas. I've forgotten way too much. I apologize. Just want to get a very OLD dinosaur to run W2K/SP4 @512MB, which mpc.com tells me is possible. I need to retire from this hobby.. One day maybe!

Re: [H] When will we see DX10 Video Cards?
I'll probably wait until Vista comes out to build. I mean we are only looking at January or February. I was hoping some decent options for DX10 video cards would be worthy of purchase by then.

Re: [H] mem question
Harry, Thanks for the informative reply. I'm still thinking about some of it. To answer some of it, a) believe the memory voltage is 3.3vdc. b) the motherboard is a dual Pentium Pro from Micronics with only one Pentium Pro 200. c) the chipset is the 440FX. d) the PC is a Micron Millennia Pro2, revB. e) motherboard has 4 x 168-pin DIMM sockets. There are no SIMM sockets. The system currently has 4 Micron DIMMS, each 32MB, that are ECC, buffered, and EDO. I do NOT know whether they are also registered. Suspect that they are based on what my Brother said he paid for them way back when! I have contacted the tech support folk at MPC.com (current support of all Micron PCs and have been told that the Millennia Pro2 was tested and certified to use 128MB EDO DIMMS. And that the DIMMS do NOT have to be buffered or ECC or registered. Just 60ns or faster. I do admit to some confusion here. But I do remember reading some spec or technical paper (prior to DDR Ram and Rimbus RAM) about changing the outboard notch of the DIMM pwba for inter-operability. I recently took delivery of 4 128MB unbuffered 60ns EDO DIMMS. Somehow the parts puller sent me SDRAM DIMMS. They do not fit my sockets because the outboard locating notch is closer to the center notch than on my current DIMMS. This purchase will be RMA'd on Monday. Source says they understand and believe they have proper replacements. I'm not so sure. I am just frustrated by this creeping technology. I'll get over this one too! :) Best, Duncan On Fri, 27 Oct 2006 02:25 , Harry McGregor [EMAIL PROTECTED] sent: Hi Duncan, EDO dimms came in two versions, both 168Pin.
