hi .. i just up graded my 2008 macbook 13" 2.4GHz with samsung one:

this is what i can see from the "About this mac":

Memory Slots:

ECC: Disabled

BANK 0/DIMM0:

Size: 2 GB
Type: DDR3
Speed: 1067 MHz
Status: OK
Manufacturer: 0x80CE
Part Number: 0x4D34373142353637334548312D4346382020
Serial Number: 0x446EA3FD

BANK 0/DIMM1:

Size: 2 GB
Type: DDR3
Speed: 1067 MHz
Status: OK
Manufacturer: 0x80CE
Part Number: 0x4D34373142353637334548312D4346382020
Serial Number: 0x446EA3FE

I just worry one thing, supposedly Mac recommend to use DDR3 1066 MHz, but I only come to notice that my new RAM is DDR3 1067MHz, will this cause any serious detrimental effect to the machine? because sometime I experienced so called "hang" and have to restart the mac while doing multiple task at the same time. Any advice? thanks

Thanks David,

I am using Macbook 13" 2.4 GHz (2008), I still have the original 2G RAM module with me. Maybe I should try replacing them back, means downgrade from 4G to 2G, to see whether it get back the stability or not. Hope this will help. ^^

Hi David,

I have tried replacing the original 2G RAM for few days, everything seem okay. So I went back to the shop, and I got a new replacement for the 4G RAM, its not Samsung anymore, he replaced the faulty Samsung 4G RAM modules with 2x Transcend 2G modules (204P DDR3 1066 SO-DIMM). Hope this work !

Thanks again..

P/s: this is the data sheet for the Transcend module http://www.transcendusa.com/support/dlcent...U-2G_2840_s.pdf and the product info http://ec.transcendusa.com/product/ItemDet...D=TS256MSK64V1U
