Memory deal. Compatible?

I found this deal on 4gb of notebook memory from fry's.

I was just wondering if this would be compatible with my MBP?

 

Yes, that looks like standard DDR2 667 SODIMMs so it should work.

Note though that only Santa Rosa MacBook Pros, ones with the 800MHz FSB, support full 4GB operation. The original Core Duo MBP only support 2GB, and the Core 2 Duo MBP with 667MHz FSBs support 3GB.

 

That will work fine on your MBP!

 

I have a current gen C2D 2.4Ghz MBP. It says the bus speed is 800MHz, not 667. So will it use the full 4gb of memory?

 

Mac OS X Tiger and Leopard are 64-bit, there won't be a problem recognizing all 4 GB!

 

Alright, great. Thanks for the quick response

 

It's not an OS limitation. The older Napa platform with 667MHz FSBs mapped the address space of expansion cards to the lower 4GB, so the full 4GB of RAM couldn't be used. Santa Rosa chipsets with 800MHz FSBs moved the address space of expansion cards above 4GB, so the full 4GB of RAM can be used. Montevina has since expanded RAM support to 8GB.

So kthung's MBP supports the full 4GB since it's Santa Rosa based.

 

jump on that deal. I caught a deal on newegg a while back for $40, and I was able to sell my original memory for $30...

 

That is an awesome deal. I agree with masterchef, jump on it and fill out the rebate form.

 

Oh, thanks for the correction, ltcommander_data! I was thinking the original poster was worried about how 32-bit XP/Vista doesn't utilize 4 GB of RAM so that's what I meant with my post!

Doesn't the macbook require 'fully buffered' mem? This Kingston RAM is unbuffered.

Note: I'm going to seriously look at the new Macbooks/pro and would upgrade the ram config.

Thanks

The only Mac that uses FB-DIMMs is the Mac Pro, since FB-DIMMs allow for very large capacities and various error correction and redundancy options. This is really only necessary when near 100% stability is required such as server or special workstation environments.

All other Macs use SODIMMs which are unbuffered and is the same type of memory you would find in any other notebook. There should be no need to look for special RAM for a MacBook or MacBook Pro.

 

Thanks for that clarification.

It's interesting that vendors seem to push the FB mem for Macs. I wonder why that would be. .................... kaching!

What's the CAS latency on these? I've read somewhere that they were 6 so i was a bit hesitant about it being slow. Maybe i should spend the money on a 7200rpm hdd instead.

 

What do you mean these? The standard CAS latency for DDR2 667 SODIMMs is 5, which is the same as what you would find buying from third-parties as well as what Apple includes in their stock configuration. It is possible to get DDR2 667 SODIMMs with 4-4-4 latency like what I have, but it doesn't really make a performance difference. The results I got from my benchmarks was something like a 8% synthetic improvement in memory latency, which doesn't really make a huge difference in the real world. I noticed a much bigger speedup from the increased RAM size.
