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.

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.

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/

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.

Easier way is:

1. Hook up your new HD to your MBP using USB/Firewire.
2. Clone your HD to it using Carbon Copy Cloner which is DonationWare. http://www.bombich.com/
3. Install new HD into MBP.

Done.

That's what I usually do if it's the same or same type of Mac.

Added on February 18, 2011, 11:31 amFurther to this, why not save more and get an SSD. I used the XT for 2 months and wasn't that impressed with the speed. Initially you'd find that it's fantastic because of the fast boot times but after a while, it's just a 7200rpm HD. I think you might be disappointed.

Yes, sorry I assumed you have one. A cheap one is only about RM20-30.

Not sure what's a good 7200rpm HD.

Press D when you turn on your Mac. You'll also need to have either the 1st OS X DVD or 2nd DVD (the ones that came with your Mac) in your Superdrive as it loads AHT from there. For my MBP 2010, it's the 2nd DVD.

I assume you asked the local shops already? They said dun have isit? Can you get them to order it?

6GB is the max your iMac supports right? You can get 4GB DDR2 from OWC.

I dunno if Kingston or Corsair has them locally. I spose you already asked.

I used a PC to boot from the ISO and did the update there.

There is? Thanks for the info. Didn't realise that. Do you have a link?

@ zXJaMeSXz: Here's an article re updating using the ISO image. Hope it's of use.

No probs, I search and search and couldn't find a Mac version.

I also have 2010 MBP 15", I have used both Corsair 1066Mhz and 1333Mhz, 2 x 4GB with no probs. Dunno the model no but it's the cheap one. About RM125 each in LYP now.

Thanks for a very informative post. I totally agree with you. I have both Corsair 1333 4GB x 2 DDR3 and a Corsair F240 SSD in my MBP and they are working great. Makes the machine absolutely screams.

One thing I would add is that the new MBPs are SATA 6GB/s so one might consider going or waiting for a SATA3 SSD. Currently the only one available is the Crucial C300 but I think more will come very soon as Sandforce has released the new SF2000 chipset. Look out for the Vertex 3 soon.

Locally, dunno, but you can get OWC stuff from macsales.com.

I don't think there's a 16GB DDR3 module at all.

I see what you mean. That's actually 2 x 8GB modules. Nice, I didn't know the MBP supports up to 16GB. very good to know. A bit overpriced though.

Rember is just a GUI for memtest. You can get an Mac installer for memtest here http://www.command-tab.com/2008/01/11/how-...under-mac-os-x/

or the memtest source from http://www.memtest.org.

Best way is to boot into single user mode and run from the command line. That way it can test all the ram.

If you were too quick in updating the EFI firmware, you might have a problem. More info here:

Bought Kingston KVR 2 x 4GB for RM132 on Sunday. Anyone else got cheaper? Also from Viewnet, LYP.
