 |
|
Hi, I inherited a computer from an in-law, with 128MB memory (thats the computer, not my in-law). I want to add more memory, but Im not sure what kind to buy. On the sticker on the card it reads
| Code: | SILCOM
NSU01664B3BA1PC-75
128-MB-PC133-333
PA3421 0208 SN 2842 |
I've got some 100MHz SDRAM lying around which fit the socket. But when I stuck it in, I got an error at boottime. Could it be that 100MHz and 133 MHz are incompatible? Since it fit, Im guessing that it must be an SDRAM (Am I right?)
Next, I've seen that theres something called SDRAM EEC. Also buffered/unbuffered and parity/non-parity SDRAM. Does this really matter? Assuming I have SDRAM, can I just buy some more SDRAM of any type and expect it to work?
Any tips?
Just to be on the safe side, here's some stats:
| Code: | fimblo@fingal wilbur $ cat cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 1
model name : Intel(R) Pentium(R) 4 CPU 1.80GHz

fdiv_bug : no

Your best bet would be to identify the motherboard rather than the ram.
Check out the Crucial Memory Advisor Tool: http://www.crucial.com/index.asp
It will tell you what kind of memory you can put in your system. |

I have never seen P4 with SDRAM.
But I can be uninformed ...
But diferencies between SDRM and DRAM is that SDRAM has 2 "holes" (DDRAM has only 1, (also you may have RIMM)) at the side which you are plugging in.
And dont't except PC100 to work as PC133, i have tred it once, but it didn;t work.
ECC memory is more expensive, and I don't think you will need one.
