Greetings,

i have an opportunity to buy Ultra Sparc 10 at bargain price but it comes
with only 128 Mb memory and 9Gb SCSI Hd. Plan to install Sol 9 but 128 mb
seems too slow to go with it.
Is it true that Ultra 10 uses ordinary PC SDRAM, that is 133 Mhz SDRAM ram ?
what RAM type can it take , 64, 128, 256 Mb ?

thanks in advance

No, the U10 does not accept PC SDRAM

You need Sun memory, or compatible.

That's right...

No, the U10 takes ordinary EDO DIMMs but no SDRAM. EDO DIMMs were common
with old PowerMacs (Pre-G3 aera) and PentiumPro computers...

AFAIR the max. it can address is 4x128MB...

Big thanks !!

is that ordinary pecee EDO RAM ? I guess it must be with parity ?

I have a U10 run 4x256MB. You can get 256MB sticks for these
systems.

You can find the information you need here:

Yes You're right. My fault, sorry...

Be careful! EDO is just the type of memory (means: which ICs are soldered on
the stick), SIMM and DIMM are the mechanical formats (circuit boards)...

EDO RAM used in PCs usually was in SIMM format (PS/2 format to be more
precise). EDO _DIMMs_ were only used for a short period in standard PCs
(PPro and very early PentiumII with i440FX chipset) and a bit longer in some
PC server models (i.e. HP LH4 series)...

The U5 and U10 use the same motherboard - the problem is mechanical.
The early 256M DIMMs used by Sun are too high to fit in the U5.
You can use some 3rd party 256Mb DIMMs for a max of 1Gb if they are no
higher than the Sun 128Mb type.

Not if you yank the floppy 8-) Somebody make me a decent offer on a U5
with 9Gb disk and 1 Gb ram.
