Hi all,
I got problem here. juz newly bought mbp 13" 2.4ghz with ram ugraded 8gb and 500gb hdd. After 3 hours playing around for 1st time, my mbp freeze when trying to restart.
Figured out the ram used is Mushkin 991647 - 4GB DDR3 PC3-10666 9-9-9-24 Essentials x 2 pcs. And hdd is WD5000BEVT SATA (WD Scorpio Blue)



The sympthom is the spinning wheel freeze while displaying grey screen with apple logo.

My friend tried PRAM/VRAM/SafeMode/Diskrepair/etc but still the same.

What could be the actual root-caused? Is it ram itself or hdd?

Pls help since i have very limited knowledge on this machine...many thanks

Ps. ....so frustrated and despair.....

You need test it one by one...last time also had same problem with WD Blue 500GB. After changing to Seagate, now no problem.

Did you install any accessories and/or apps before the crash?

You can try booting into Verbose mode and see where & what cause the freeze.

First have you try place back the stock RAM?
Does it work? If no then move on.

Put in the DVD came with your Mac, hold down C then power on. See if that boot.
If yes, then your boot volume is not booting, need repair or reinstallation If no it could be hardware related.

did WD Blue got warranty? in case i need to RMA

1. well, when i turned online, got notification for software update. i did d/load the sw-package and installed, later it re-started the mbp, where it freezeing all the sudden

2. i do not have the stock RAM or original RAM...forgot to ask back when upgrading

3. DVD can be inserted, it can boot, try select the DVD-drive icon, but it still freeze again while try to load/read the DVD

4. If RAM-related, what the best RAM to be used?

3. Please confirm you are booting from the DVD. Sometime it will boot from the HDD if you did not press "C" soon enough or let go too early.

Insert the DVD and restart/re-power on holding Options (alt) key. You should see similar screen like this (but with less icons):


Select the DVD icon to boot.

hi wei,
what is the proper steps again? i'm bit confuse when tto press C-button and when Option-button...thx

Keep holding Option (alt) when you power on/restart. Until you see similar screen I posted. Let go. Choose the DVD to boot. You can also put in the DVD during that screen and wait the new icon pop ups.

pressing the Option button (after the chime, before apple logo comes up) will let u pick where to boot (dvd, another partition, another hard drive etc) just like in the photo

pressing C means picking to boot from the dvd drive only

anyway yes WD blue got warranty, i've successfully RMA'd before.

since u dont have ur original RAM, try install back ur stock HDD. if can boot, then the WD blue may be faulty. u can also take out one RAM, n try boot. if can boot, meaning the RAM u take out is faulty

hi experts,
problem solved! managed to get back to seller and he installed back original ram and things back to normal again...:-)

surprisingly, the original ram is SAMSUNG brand, i thought Kingston KTA, am i been conned?? :-(

No, Apple is known to use Samsung, Micron & Hynix for stock RAM. Never Kingston (unless in early PPC era). KTA is trusted DIY upgrade option.

KTA is good but it's a third party RAM. kingston tests the RAM on macs, but apple never configured KTA as a mac's stock RAM

samsung RAM is normal. samsung is a huge memory supplier

many thanks for clarifications...will opt for KTA on my next upgrade + SSD....

Almost all big brand will have Apple RAM. Crucial, corsair, kingston, micron, mushkin, OCZ... Just that, can you get them here or not.

one seller in LYN could help you to get it....best price for KTA 8GB is rm500. still searching around if got any cheaper

how is freeze screen look like? i got kernel panic not sure if it's the mushkin ram problem or not...so confirm it's ram problem?

same as yours....frozen grey screen with apple logo and spinning wheel......
the culprit is Mushkin ram....restore the stock ram Samsung, failure gone, till now....

who is the seller. looking to upgrade to 8gb.

Tot yours WTS?

Your MBP is the latest 2011?

nope, it's mbp 13" 2010....bought from famous ajul...recommended seller

2010 model is using 1066mhz ram.. i think u bought the wrong one that'y freeze...mine is 1066mhz working like charm

Yes, you can find Mushkin RAM in Malaysia, that is specific for Apple.

RAM that is specific for Apple cost u 3x more...

heard from ppl that kingston is the best choice of RAM for MAC ?

yup, mushkin RAM purchased from ajul as well, as he claimed even using 1333MHz ram doesn't matter as the system will capped at 1066Mhz only...

guess, he was wrong and me just unlucky.....
