yeah i realized some sellers in garage sales havent update their prices for 4gb ddr3. the standard price now is ~120 for 1066mhz n ~160 for 1333mhz. perhaps u can PM them n ask what's their latest price

quite a few forumers using this. i'd say upgrade to momentus XT 1st (well proper SSD better lah if money is no problem), sure got improvement for RAM, u wont feel the improvement if u dun need 8gb

i been use for 3 months ago.
the performance 2x faster than normal hdd but for sure ssd is more faster
check at viewnet last time i bought rm399 for 500gb.

mine is mBP15... i bought it in Taiwan actually, at the NOVA shop which is kinda popular there. for NT$8600 which is about 900 ringgit

so should i look for a 1066mhz or 1333mhz instead? because if im not wrong a 1333 unit will automatically underclock to 1066, is it true?
now system info show im running with 1067mhz.

and which shop can provide at shop installation for the rams hehehe ..bit afraid do it by myself

might needed 8gb asap ..during heavy tasking page outs around "180,000" ..hehe 6 digits

well 1066mhz is actually 1066.66666... dats y system info round up to 1067

yea 1333 will underclock to 1066. but 1066 cheaper ma

hehehe so basically hook up 1333 buang duit lah eh?

if u can find 1066mhz enough already..but not much stock in market..price also not much different with 1333mhz..

I installed 2 x 4GB 1333Mhz into my MacBook Pro 15". Brand is Corsair, price RM125 each from LYP. So far working OK. My previous MBP was using Kingston Valueram 1066Mhz, also no probs.

We all know that 1066 ram has a cache latency of 7 and 1333 ram is usually 9. So what happens to 1333 ram running at 1066?

Installation quite easy. Just remove all the screws at the back. Pop out the old ram and in with the new.

I have also installed Corsair 2 X 4GB into my Mac book 13".
So far running OK, system is noticeably faster than my old 2 X 1GB RAM.
Paid RM130 for each stick.
Now looking for 7200rpm HDD.

For those not sure about 1333Mhz, 1066Mhz still plentiful at LYP when I was there 2 days ago. I think the price is the same as the 1333 I purchased, maybe slight, RM5, cheaper.

which shop have corsair 4gb 1066mhz? wanna get one next week. max out 6gb ;p

I just bought two 4gb DDR3 1333 ram to upgrade my Macbook Pro 2010.
Unfortunately it hang while it's booting the com when I put 2 4gb DDR3 1333 ram. However it work find when I put 1 4gb DDR3 1333 ram + 2gb orginal ram.
May i know can the macbook pro 2011 support two 4gb DDR3 1333 ram ?
or is it better for me to put one 4gb DDR3 1333 ram and one 4gb DDR3 1066 ram ?

it should support

u said it works with 4gb + 2gb right? what if u swap the 4gb with the other 4gb one? does it still work? just to check if one of the 4gb stick is faulty

Viewnet has them. Same place I bought my 1333.

Added on February 17, 2011, 12:48 amGo to the shop and try another pair. Maybe a bad stick or a marginal one. What brand of DDR3 are u using? MBP 15 or 13"?

I've used 2 x Kingston Valueram 4GB 1066 in a 2010 MBP 15" i7 2.66, no probs for about 7 mths.

Now using 2 x Corsair 4GB 1333 in a 2010 MBP 15" i7 2.8, only 1 week but so far no probs.

MBP 2011, if using Sandy Bridge, will require 1333 Ram but as always, when using 3rd party RAM, YMMV.

You can try running Apple Hardware Test on bootup to test the ram. It's not as thorough as memtest but should be good enough to detect bad ram.

You can also use Rember, basically a GUI for memtest. http://www.kelleycomputing.net/rember/

update : bought 2x Kingston 1066 for rm130 yesterday at C-Zone .. so far so good.

Yup I did it. It work when it's compatible with any of my 4gb . But when I put in 2 x 4gb it hang it when I see the 'apple' logo.

any significant battery life issues after using momentus XT? i think its time to upgrade my MBP (mid 2010) as well

How about 1 stick of 4GB all by itself, does that work?

Added on February 17, 2011, 4:13 pmI used the XT for about 2 months before upgrading to SSD. I didn't noticed any significant change in battery life. In theory the XT should use more power, right? Since it's 7200rpm compared to the stock Apple HD which is 5400RPM. Only thing I noticed is that it runs hotter.

Sounds good. Will grab one soon.

Guys, restoring a new he'd is as easy as;

1) install OS with disc

2) run time machine to restore

Correct?

@kosy90 it highly depends what chip is on the 1333 module. I suggest you return the pair for another brand or different part#.
