Solve : RIMM memory? |
|
Answer» Hi folks, The current config is 2 x 64 Mb RIMM memory. A computer shop down the road installed another 2 x 128 MB RIMM memory. But after the machine is user-ready and after maybe 5 seconds it quits completely. Any ideas how it can be upgraded and still keep working for me?Memory caused the failure? You don't say. You don't even provide any facts that say 'why' it failed. Is memory defective? Did he install the wrong memory? Are interface drivers to those second slots defective? Answers always begin by learning what you have and do not have. That is what DIAGNOSTICS are for. Memtst86 used in conjunction with heat is an excellent diagnostic. Execute memtest at normal room temperature. Then repeat the test again either in a 100 degree F room or with memory heat by a hair dryer on highest heat. Both are pig’s heaven happy temperatures to all semiconductors - and how defective memory finally reveals itself. The original config was 2 x 64 MB RIMM Memory, the guys from computer shop added another 2 x 128 MB RIMM. So no more slots are free (4 of 4 used up). Because that didnt work for me the guys removed the later on added 2 x 128. Now we are still at 2 x 64Mb. The guys from the computer shop hadnt a clue either why my machine didnt work with the added memory. Thats why I turn to this site for expert-opinions and hopefully a solution. I dont know the added on memory was mew or already used but it certainly caused my machine stop working properly. With the new added on memory the machine and therefor the OS started up fine, I saw the desktop screen with all icons but after maybe 5 secs it went dead. The manufacturer told me I could upgrade to 2 Gb. Maybe all slots should be even divided, so 4 x 512Mb RIMM??? Sounds ridiculous to me but hey I am only a newbie at this. RobertAnd to add; Is RIMM memory still available somewhere in this universe?So what chips are currently installed? Can you pull out the new ones and try to boot? What HAPPENS if you do?Quote from: haighton on July 04, 2009, 07:35:25 AM The guys from the computer shop hadnt a clue either why my machine didnt work with the added memory.BIOS first learns what memory is by talking to a special INFORMATION pin. For example, setup for a two chip memory is different from the same size memory USING eight chips. Some computers may understand the eight chip memory but be confused by a two chip memory of same size. Also timing may be different between memories of same size. One reason to go to a major memory supplier (ie www.crucial.com) are the charts that state which specific memories work in which machines. Memory is more than its pinouts and memory size. Other parameters apply. Quote from: Quantos on July 04, 2009, 07:39:12 AM So what chips are currently installed?I cant pull the new ones out bec those computer shop guys already pulled those 2 x 128 Mb as my machine didnt work with the new added memory. At present I only have the original 2 x 64 Mb (as from the day of purchase). RobertIt's possible that the RAM that they put in was bad. Does the machine boot okay now though?To add (again) but now from the original invoice spec: 128 Mb NON-ECC RDRAM (2x64) 400 MhzYes it boots okayThe only thing that I can think of is that the RAM that they put in was bad. I have a whole baggy of old ram, PM me and I'll mail it to you.I got 4X128MB RDRAM from Amazon and maybe there are 512MB RDRAM sticks. |
