SYNOPSIS: SIMM memory install in SS5, SS10, SS10SX and SS20 (order of
install placement in motherboard).
HARDWARE: SIMM for SPARCstation5.
HARDWARE: SIMM for SPARCstation10.
HARDWARE: SIMM for SPARCstation10SX.
HARDWARE: SIMM for SPARCstation20.
OS: Any
ORIGINAL QUESTION:
Does anyone know what the install order is for memory SIMM into a SS10
and SS20 (i.e. which slots to fill first in what order) ?
POINT OF CONFUSION:
The front for a pizza motherboard is the back of the pizza box. With the
case removed, look into your pizza box from the back standing behind it,
you will see eight SIMM slots at the rear of the motherboard near the
hard drive mount points. That is the back of the motherboard.
DETAIL DESCRIPTION FOR A SS5:
The layout below is from "Sun Installing SPARCstation 5 DSIMMs" dated
2/94. The layout is presented in order as found on the motherboard when
it is viewed with its front towards you, reading from the top down (from
back to front). Each row represents a SIMM slot and shows its slick
screen label, its install order, and its memory address range.
J0403 7th 0e000000-0fffffff
J0402 6th 0c000000-0dffffff
J0401 5th 0a000000-0bffffff
J0400 4th 08000000-09ffffff
J0303 3rd 06000000-07ffffff
J0302 2nd 04000000-05ffffff
J0301 1st 02000000-03ffffff
J0300 0th 00000000-01ffffff
DETAIL DESCRIPTION FOR A SS10:
The layout below is from "Sun Field Engineer Handbook" dated 12/5/97.
The layout is present in order as found on the motherboard when it is
viewed with its front towards you, reading from the top down (from back
to front). Each row represents a SIMM slot and shows its slick screen
label, its install order, its memory address range.
J0305 7th 1c000000-1ffffffff
J0304 2nd 0c000000-0fffffff
J0303 5th 18000000-1bffffff
J0302 4th 08000000-0bffffff
J0301 6th 14000000-17ffffff
J0203 3rd 04000000-07ffffff
J0202 8th 10000000-13ffffff
J0201 1st 00000000-03ffffff
DETAIL DESCRIPTION FOR A SS10SX and SS20 (Netra /20, Netra s20, Netra
i600, Netra i625):
The layout below is from "Sun Field Engineer Handbook" dated 12/5/97.
The layout is present in order as found on the motherboard when it is
viewed with its front towards you, reading from the top down (from back
to front). Each row represents a SIMM slot and shows its slick screen
label, its install order, its memory address range.
J0201 0th 00000000-03ffffff
J0202 2nd 08000000-0bffffff
J0203 5th 14000000-17ffffff
J0301 3rd 0c000000-0fffffff
J0302 6th 18000000-1bffffff
J0303 1st 04000000-07ffffff
J0304 7th 1c000000-1fffffff
J0305 4th 10000000-13ffffff
Note: Some old SS20 doc state the SIMM order as 0 - 7 relative to J0201
- J0305, this is wrong!
OTHER SIMM NOTES:
1. Memory for SS10-SS20 does not need to be installed in pairs.
2. Install highest capacity SIMM in first.
3. Bad SIMM in first slot (1st on SS10 0rd on SS10SX/SS20) will prevent
system from booting.
4. You can use memory from new models in older models but you can not
use old memory from older models in new ones.
5. SS10 & SS20 can take 8mb-64mb SIMMs.
6. SS10 SIMMs run at 70nsec.
7. SS20 SIMMs run at 60nsec.
COMMENTS:
I appreciated the many responses that I received. I called SUN SERVICE
and received a 10 page fax which the above SS10 and SS20 information is
based on. The SS5 information is based on a fax I received from Charles
Best and is included in this summary for future reference by others.
THANK YOU:
I would like to thank the following people for their responses,
particularly Charles Best and Ellen March who faxed me additional info.
