8GB of ram question for macbook pro 5.1 (It works!)

[DoFoT9]

who knows, the architecture supports that speed - whether or not Apples logic boards does is another story.

Keep in mind in this forum we seem to talking about two different breeds of MBP. While the 2009 Intel Core 2 Duo and the 2010 Intel Core i5/i7 models look the same, both being unibody and all, (don't argue with me, I just built a Core i7 desktop) they are TWO radically different machines in the way they handle RAM.

I'm aware in the 2009 unibody Core 2 Duo models that they wouldn't play nice with the 1333Mhz RAM, but the Intel Core i7 chipsets use a different chipset so I'm wondering how the 2010 Intel Core i7 models would handle 8GB 1333Mhz RAM.

you built a core i7 desktop? what does that have to do with notebook architecutres? we dont know if the apple logic boards can take those speeds until somebody tries it. the architecture itself can handle 1333 as i said, but that doesnt mean much when it comes to Apple computers.

OH! Forgive me. I was referring to the Intel Core 2 Duo and the Intel Core i7 being radically different CPU's requiring entirely different chipsets.

You are correct, it will depend on the Apple logic board. I *literally* just got done arguing with someone that was bent on the Core 2 Duo and Core i5/i7 processors being built the same way (they are not).

I'll buy the 8GB DDR3 1333Mhz and try it out. Worst can happen is it eats it and I have to reinstall the OEM 4GB DDR3 RAM and order 8GB of 1066Mhz (returning the 1333Mhz of course).

ooohhhhhh! haha - yup no arguement there. i wouldnt have bothered!

on previous models, the RAM was "shaped" back to the 1066MHz and worked flawlessly, this was for previous iMacs and MBPs. i am not certain of the current gen models and any faster RAM (if it exists).

Ordered these:

According to UPS they're due in tomorrow. I'll keep you guys posted as how it all works out.

So I installed them. It did in fact throttle down to 1067Mhz. I read somewhere it had to do with the RAM being CL9 instead of CL7, but who knows.

It does run noticeably faster though. My boot up speeds doubled. So, we'll see...

Obviously iMacs are NOT MacBook Pros, but I find it strange that they DO take the CL9 1333Mhz RAM while the MacBook Pros do not.

I have a 30-day return policy from Tiger Direct so we'll see if it borks on me in the next few days. I found a place that might have 2-4GB 1333Mhz CL7 SODIMM modules so I'll call in the morning. I'm a little OCD about making sure my RAM is operating at the correct speeds. I've had issues with this in the past.

The modules finally arrived! Ordered last friday... arrived today (friday) so 1 week isn't too bad from newegg (their much faster shipping to the USA than to Canada).

Anyways, all in all it took about 5 minutes to crack the case, take out the old modules and insert the new ones. Very easy to do.

Starting the mbp up with the new modules in was very odd. I do have a SSD but my boot times after owning it for a year are around 18-24 seconds... usually 24 flat all the time.

It was literally 14 or 15 seconds to boot this time. Must be due to the fact that the Cas Latency is slightly lower than my previous modules (faster time transfering data to and from the SSD to RAM).

Just thought I would let everyone here know that you can install 8GB of ram in a March 2009 mbp (before Apple "officially" said that they support 8GB of ram in june).

SSD and 8GB of RAM?
I see money is no object...

 

[boredsadist]

SSD seemed a little much, though Seagate makes a SEXY SSD/HDD hybrid drive that I might want to get my grubby little hands on. I've heard several reports about boot and load times flying through the roof.

I booted into Windows 7 (through BootCamp, NOT using Parallels like I normally do) and CPU-Z (as I can interpret) identified my 1333Mhz modules and showed the machine using them. I'll post my specs from CPU-Z here.

Keep in mind I have an USB card in my express card slot. (not that it matters, but some people might notice the strange extra USB entries and YES I needed the fourth USB port )

Hi Everyone,

I've been searching for a thread like this for months. I've through the whole thing but I'm a bit noobish with the technical Jargon.

I'm currently using a 2nd generation 2.66 unibody mbp with 4gb of RAM (original).

I bought 2x 4gb 2Rx8 PC3-1066S-0910-F2

that's what it says on the chip.

I tried installing 2 of them myself, but the OS wouldn't boot.

I put in 1 4gb, and left 1 original 2gb. and it seems to work but I have no idea if it was using 6gb.

Can anyone tell me how I can use both the 4gb chips? It would be much appreciated

Sure it's a 5,1?

Hey,

This thread was confusing to me. To the OP: are you sure you have a 5,1? I was under the impression that 5,1 cannot run more than 6 GB. My understanding was that this had to do with the power delivery to the RAM modules. I have a 5,1 and thought it could only run 6 GB and not 8 GB. Are you sure you have a 5,1 and running 8 GB?

Clarification would be appreciated. All other unibody MBPs can run 8 GB.

Ram 1333 mhz macbook 5.1

Hi guys
I've got a MBP 15" bought in mid 2009.
Today I've made an upgrade of the RAM with brand new 2x4GB 1333 Mhz. It's working very fine so far at 1333 Mhz. Now it's much faster when I'm working with Final cut, Motion and Photoshop CS4. I Bought the cheapest ones, but they work fine.
