How many sticks are in this Macbook Pro?
February 22, 2007 2:39 PM   Subscribe

I'm thinking of buying a refurbished Macbook Pro from Apple, but I want at least 2 GB memory. Most of them have 1 GB, but I don't know if it's using two slots (512x2), or just one slot with the second one open. Is there a way to know by looking at the description?

Under memory, it says "1GB (single SODIMM) 667MHz DDR2 SDRAM (PC2-5300)"... how can I know for sure? I have no problem buying a new 1 GB stick, if the slots available, but I'd hate to buy it and find two 512 sticks, and then need to shell out for two 1 GB sticks.

Any suggestions on how I might find out?

Apple always splits up RAM between two sticks, so if you're buying it from Apple and it's got 1G then the configuration will be two 512M PC5300 SO-DIMMs. They make specific performance recommendations about matched RAM pairs. I dunno why they're saying it's a single SO-DIMM.

All Macbook Pros ship with only one RAM slot used.

Additionally, the extended description of a given part will always say. For instance, the one MbP I see on Apple Refurb right now, a 2.16 GHz 17", says on the second line,

1GB (single SODIMM) 667MHz DDR2 SDRAM

I asked a similar question (about my Macbook) that might help.

Hollisimo, that's only now true on Macbooks because the Intel Integrated Graphics requires it.

2.0 GHz Core Duo Macbook Pros shipped with dual 512 DIMMs (the $1999 model), but all Core2 machines now ship with single 1 GB sticks (unless you configure up, of course), just as all but the cheapest Core Duo Macbook Pros did.

I should have been more specific before, for shame.

So when the description says "1GB (single SODIMM) 667MHz DDR2 SDRAM (PC2-5300)," that means there's only one memory stick, with a slot left open... is that right?

"single SODIMM" means it ships with one stick, yes.

(And when I bought a stock 2 GHz C2D Macbook Pro with 1 GB of RAM, it came with only one stick.)

Same here. Definitely go for another gig after, cause i found I was regularly floating round 1.2gb

I bought a refurb MacBook Pro with 512Mb, took that out, and stuck in two Mushkin sticks from NewEgg. Works fine.
