Will you be buying your 4 gigs through Apple or you will seek a third party ram supplier?


I know its important to match RAM and what not. I have this very sneaking suspicion I could find the same type of RAM for significantly cheaper elsewhere.

What are you people doing?



my main concern is that it ships with two 1 gig sticks. Are both sticks easily changeable or just one slot is?

It's always cheaper to buy 3rd party. OWC has 2GB sticks for something like $120 each. Both slots should be accessible unless they've changed the design significantly.
 
Both sticks you can change. I've ordered my MBP with the standard 2GB, and plan to replace one of the 1GB sticks with a 'third party' [bad term to use really, the chips are usually all samsung anyway] 2GB stick from somewhere like newegg. It's so much cheaper; in fact, I could buy two 2GB sticks for AUD$400 if I really wanted to match them, and it's still a few hundred cheaper than the Apple 4GB BTO option.

I believe there's a few links floating around on these forums if you want some 'evidence' [benchmarks, etc], but dual-channel won't make as large as difference as say, another 1GB of RAM would.
 
Just curious does anyone know why the speed of the RAM is still 667mhz and not 800mhz like the bus speed. Or am I just confusing matters.

'Coz 800 MHz SODIMMs are rare and expensive.
It may also have to do with the design of the buss in this particular motherboard, or just possibly, a heat management thing. 800 MHz chips run hotter, and most (not all) require elevated voltages of 1.9 - 2.1 V to run at 800. Higher voltages are a no no in notebook land...

Edit due to prescience... The Crucial looks fine (use the Crucial link at the top of the MacRumors if you go to buy). If you are in the USA you can also compare Data Memory Systems at $123 each (they haven't updated their list yet but it is the same 2 Gb module the prior model takes.)
 
Mr. CanadaRAM do you have anything to add to this issue?

I'd appreciate your opinion on the RAM I have selected.
 
looks to me like they just updated their specs for the new MBPs.

4GB Kit (2x2GB) 200 Pin DDR2-667 PC2-5300 256x64 CL5 1.8V SODIMM (Lifetime Warranty) DM50 190 X 2 $246.00

awesome... definitely going to do this. is there any market for 1gb memory sticks? i'll have two i will no longer need.
