Hi,
I have access to a remote linux machine. I have a root account on it.
I need to know whether the installed RAM is SDRAM or DDRAM.
Unfortunately i will be going to the site next month when i have to
upgrade the machine with more capacity. Few of them are hardware
related but if you know the answer please help me.
1) How do i find out when the machine is online , if it is SDRAM or
DDRAM. I tried dmidecode utility but i was not sure about the type.
Can someone help me out by pasting the output for both DDR and SDRAM
in dmidecode or similar.
2) Can both SDRAM and DDRAM be present at a time in the same
motherboard. I mean can i have 256MB of SDRAM chip and a 256 MB of
DDRAM on the same motherboard.
If yes what are the conditions.
3) Is a motherboard designed for only one type of RAM , like if we
remove all the SDRAMs can we put DDR in it or it is either designed
for DDR or SDRAM.
Regards
Nik

Try powertweak (text mode version), that can also yield pretty verbose
DMI etc. data. Might just provide that extra bit of information you need.
But with DMI info about the board manufacturer it should be very easy
to find on the internet what RAM type the board supports anyway!?

Yes, iff the board has both DDRAM and SDRAM slots (ECS K7S5A comes to mind,
most popularly).

Almost all boards are *either* SDRAM *or* DDRAM, to my knowledge,
only a couple boards during the transition phase offered both slot types.

Er, I owned a K7S5A, and as best as I can remember the manual was pretty
explicit that you could have one, or the other, but _not_ both at the
same time. :)

Except for very high quality server boxes don't trust the dmidecode data
for the RAM. Get the motherboard/system name from dmidecode then look it
up manually

I have a K7S5A working and when I plug a DDRAM, the SDRAM is ignored.

Can you tell anything about it ? I have IBM x-series 206 server. Here
is the dmidecode information. Is SDRAM or DDRAM installed on it. It
would be great if you can tell me where to look.

If I need to find out the mainboard chipset, I usurally look at the IDE
controler, and if you know the mb chipset, you can get the specs.

This would appear to say that socket DIMM3 has a 256MB DIMM of type DDR
at 133MHZ, which would be 266MHz effective. Odd given the x206 data
sheet I found only mentions 333 and 400MHz as supported. Maybe the DMI
data is wrong, or maybe the memory in the system isn't right.
I think the only way to know for sure what type of ram a machine takes
is to read the manual, or maybe ask http://www.crucial.com (I have seen it have
information that was correct while an IBM manual for the machine was
wrong on the amount of ram a machine could take).
Crucial's information says the system has 4 DIMM slots for DDR memory,
and should use either PC2700 or PC3200 memory.

knowing what processor and chipset the memory is attached to will tell

They are physically different form factors (168 pin dimms vs 240 pin

have two slots of either variety.
