want to add RAM...what speed?

sneakyimp · 12-20-2006, 10:16 AM

I have an oldish compaq dl360 server with debian linux installed. i don't know the exact mobo model number and there are a number of generations of the product.

I want to add RAM. Is there a linux command that will tell me what speed of RAM I need to get? My sysadmin seems to think it only needs 133mhz RAM.

Also...i don't know if it has one proc or two. Debian only reports one but the sysadmin insists it has two.

Sorry if this sounds retarded...we bought it on ebay for like $20....it's only for development purposes.

lshw should be able to tell you, although it may not be installed by default..

Heres the memory section of the output from one of my workstations that is running Debian Stable..

Code:

     *-memory
          description: System Memory
          physical id: 1000
          slot: System board or motherboard
          size: 256MB
          capacity: 512MB
        *-bank:0
             description: DIMM SDRAM Synchronous 133 MHz (7.5 ns)
             physical id: 0
             slot: DIMM_A
             size: 128MB
             width: 64 bits
             clock: 133MHz (7.5188ns)
        *-bank:1
             description: DIMM SDRAM Synchronous 133 MHz (7.5 ns)
             physical id: 1
             slot: DIMM_B
             size: 128MB
             width: 64 bits
             clock: 133MHz (7.5188ns)

how do you install it?

farslayer · 12-20-2006, 11:39 AM

# apt-get install lshw

cool! what does 'capacity' mean for the cpu info? it's nearly twice the 'size' value which seems to correspond to the current clock speed.

Capacity would be the Fastest CPU that BIOS and Motherboard was designed to support when it was manufactured..

Although past experience has repeatedly taught me that by the time the CPU's hit that speed, the manufacturer went and changed the clock frequency or CPU voltage requirements for their CPU's so they won't work in my Motherboard anyway.. **sigh**

Code:

 *-cpu
          description: CPU
          product: Pentium III (Coppermine)
          vendor: Intel Corp.
          physical id: 400
          bus info: cpu@0
          version: 6.8.10
          slot: Microprocessor
          size: 933MHz
          capacity: 1600MHz
          width: 32 bits
          clock: 133MHz

So yes my example system here has a PIII 933 in it.. theoretically I can install a 1.6 Ghz CPU in it provided the clock and voltage requirements still match.. also not that Pricewatch doesn't even list a PIII faster than 1.4 Ghz..
