Which version macbook pro is this? and how much ram?

Question

Hi Everybody!
I just bought this 2.4ghz core 2 duo macbook pro 2nd hand:-)
It's probably the mid 2007 version. It's annonced with a max RAM upgrade of 3 gb, but it's to cheap to buy 4gb (2x2)!!
How does it work? Does OSX used the last gig of ram from 3-4gb? or it is just a waste of money?
I use my macbook pro for normal use, and production in logic pro.
Thanks!

Yes, it's the Santa Rosa chipset. And yes, you have an LED backlit display and the faster frontside bus (that will read 800 MHz in System Profiler).
The MBP chipsets are:
• Core Duo - clock speeds of 1.83, 2.0 or 2.16 GHz
• Core 2 Duo - clock speeds of 2.16 or 2.33 GHz (2.0 GHz C2D chips are only in MBs, not MBPs)
• Core 2 Duo "Santa Rosa" - clock speeds of 2.2, 2.4 or 2.6 GHz, with a 4 MB L2 cache
• Core 2 Duo "Penryn" - clock speeds of 2.4, 2.5 or 2.6 GHz, with 3 or 6 MB L2 cache

I'm using the terms "Santa Rosa" and "Penryn" as they are commonly used on these boards. "Santa Rosa" actually refers to a combination of the Merom-refresh CPU chip with other chips for graphics/wireless (i.e. it's a platform, not a chip, and thus was technically never in an MBP because only the Merom-refresh chip was used, not the whole platform - but the original C2Ds were Merom-based, and "Santa Rosa" sounds better than "Merom-refresh", I suppose). Merom chips (like the Yonah Core Duo chip) were made with the 65 nm process, whereas Penryn is the successor to Merom and is made with the newer 45 nm process.
