We have several Iris 4D 20's and a 4D70 and they all want to have their memory upgraded, but SGI wants lots and lots of money to do it. The memory seems to be in the form of 1Meg simms. What is the preferred style? How fast do they have to be? The reason I ask is that if we could use mass market simms they would be at least half the price. Thanks in advance Steve Roy ssr@acm.princeton.edu Gianluigi Zanetti zag@acm.princeton.edu

SGI wanted about $ 1200 a meg for memory and we paid $ 310 a meg on the open market. We just specified 1 meg SIMMS, 100 nsec, and didn't have any trouble, they are quite easy to install, and you could probably coerce your local SGI person to help you out. We bought our memory from an place called "Sophisticated Circuits" here in Seattle, their phone number is: (206) 547-4779. My impression is that the price has come down some from this figure. D

The boards are EXTREMELY static sensitive. Static damage can be very insidious in that it may not effect the performance of the system for as much as several months, and then start failing intermittently. Be sure to use an anti-static surface and ground yourself and the anti-static surface to the chassis of the system with anti-static straps. These can be had at any electronics supply place. The sockets that the SIMMS go in can be broken easily. They are, as Mr. Davis says, quite easy to install - but be careful. The speed and size of the SIMMS isn't the only criteria for ensuring that the SIMMS will work properly in any particular system. Computer companies regularly qualify or disqualify manufacturers of various components, and memory is no exception. Memory you get from Silicon Graphics is warranted to work correctly in your system. Go to another vendor and "you takes your chances". So long.... chris -- D.
