MacBook (unibody late 2008) - RAM question

Hi All,


I am fairly new to this community but from I have seen so far there is a lot of knowledge contained in these threats.


I have a MacBook (unibody late 2008) with the following specifications:


Hardware Overview:


Model Name: MacBook

Model Identifier: MacBook5,1

Processor Name: Intel Core 2 Duo

Processor Speed: 2 GHz

Number of Processors: 1

Total Number of Cores: 2

L2 Cache: 3 MB

Memory: 2 GB

Bus Speed: 1.07 GHz

Boot ROM Version: MB51.007D.B03

SMC Version (system): 1.32f8

Serial Number (system): W8******1AQ

Hardware UUID: ******

Sudden Motion Sensor:

State: Enabled



After installing Lion a few weeks ago everything has significantly slowed down I feel that a revamp boosting RAM and memory would help. I currently have 2GB RAM (2 x 1GB) and 160GB hard drive. Hard drive details below:


NVidia MCP79 AHCI:


Vendor: NVidia

Product: MCP79 AHCI

Link Speed: 3 Gigabit

Negotiated Link Speed: 1.5 Gigabit

Description: AHCI Version 1.20 Supported


FUJITSU MHZ2160BH FFS G1:

Serial Number: K64******N6T

Native Command Queuing: Yes

Removable Media: No

Detachable Drive: No

BSD Name: disk0

Medium Type: Rotational

Partition Map Type: GPT (GUID Partition Table)

S.M.A.R.T. status: Verified

disk0s1:

Recovery HD:

Capacity: 650 MB (650,002,432 bytes)

BSD Name: disk0s3

Content: Apple_Boot


I have done some research on line and I have the following questions:


RAM

1) What is the maximum RAM my mac can take without causing problems. Apple mentions that the maximum RAM is 4GB (2 x 2GB) but I have seen mentioned in threats that up to 8GB have been installed.


2) The RAM quoted in the specs from apple is DDR3 PC3-8500/DDR3-1066. Could I use a faster chip such as DDR3 PC3-10600/DDR3-1333 or is this upgrade not advisable.


Hard Drive

1) Is there a limit to the maximum capacity re hard drive. The maximum apple used to offer this model was 320GB. I would ideally would like to go up to 500GB to 1TB.


2) The specs of my existing drive are: 160GB 5400-rpm Serial ATA hard disk drive. Could I get a faster disk, say 7200 rpm to increase performance and will this have any significant impact on battery life and heat?


Further more any recommendations in terms of any of the above welcome.


A lot of information but I wanted to offer all the info needed for meaningful advice.


Thanks in advance.

According to the information you provided, here's your MacBook's full specifications:


MacBook (13-inch, Aluminum, Late 2008) - Technical Specifications

http://support.apple.com/kb/sp500


RAM


(1) Officially It says it 'supports up to 4GB'. So play safe — install 2 x 2GB RAM. You may go here: http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade as they generally have some model-specific advice beyond Apple's official suggestion. (6GB in your case) However, some other users suggest that 8GB RAM may work while some say it only recognises 6GB out of 8GB.


(2) To the best of my knowledge, if you install 1333MHz RAM in your MacBook (officially supports 1066MHz), your RAM will just run at the speed of the bus (i.e. 1066MHz) unless the bus is faster than the RAM speed which is not the case here.


Hard Drive

(1) You can install a 500GB hard drive in your MacBook without any problems. If you can find one, you can install a 1TB hard drive, too.


(2) Generally, there will be negligible decrease in battery life or increase in heat. So it might get warmer and the battery life may be reduced as much as 10-15 minutes.


You may go for an SSD instead of HD for significantly faster performance. If so, do a fresh install of OS X Lion instead of cloning the system onto it.


Hope it helps. 😉

Hi there,


I know it's been a long time you didn't answer in this tweet but I'm having some trouble with my 8G upgrade RAM !

and I hope you would be abble to help me 😀


I have a macbook aluminium late 2008, and you will find all its informations belong :


Version de la ROM de démarrage:MB51.007D.B03
Version SMC (système):1.32f8


I'm running Moutain Lion version Logiciel OS X 10.8.5


Bt my problem is my 8G Ram was not recognized by my macbook so when I put it inside a really weird noise appeared (like biiiiiip biiiiiip biiiiiip) and I've seen on internet it means it's a non-recognization of my memory ram 😟


I bought this RAM :


Kit 2x4 Go SODIMM DDR3 1066 MHz PC8500


Does someone here could help me because i'm really lost, i have the good BOOTROM Version .... so it should have worked... 😟


and then I also tried to upgrade my EFI to the 1.4 firmware but it doesn't want to be installed on my macbook saying "My macbook doesn't need this upgrade".


If anyone hears me: THANK YOU 😀 !!!

I was reading through dubious opinions on this, so I decided to give a try. I have the original unibody 13" MacBook.


The ram I purchased is CORSAIR Vengeance Performance 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model CMSX8GX3M2B1600C9 (http://www.newegg.com/Product/Product.aspx?Item=N82E16820233588). It runs at 1.35V, too. The only spec that doesn't match is the clock speed, which is 1600 instead of 1066/1067.


When I installed the new ram, my MacBook refused to boot. As soon as I turned it on, it emitted several beeps while the screen remained black. That's it, nothing else happened.


I tried several users' suggestion of leaving one of the old RAM chips working with the new one, in order for the motherboard to use the correct clock speed. Same exact thing happened -- my MacBook did not boot. I replaced the original RAM chips, and it booted just fine.


In conclusion, whether it's the clock speed or not, the Corsair chips are certainly not compatible with my 2008 unibody MacBook.

hi guys,


first of all thank you for your very quick advices 😀


So I called Macway technical service and I'm gonna make an exchange for the CRUCIAL RAM (same spec as before 1066 ...) hoping they will be okay with my macbook !!


they unfortunetaly don't have the OWC one ... but let's cross the fingers these one will be fine as well ^.^


my SSD is a crucial one and it goes very well with my laptop so I hope Curcial RAM will go too... Anyway I'll tell you when I receive the package 🙂


thanks again 🙂
