@Surveylol No, it's just something recommended, but not absolutely necessary. However, if you run production apps like Final Cut, Photoshop, InDesign etc. It would be beneficial for you to do a test, so you know for certain that the New memory has no errors/issues and is good to go.
@Mac4072 Software that stress tests your system memory to make sure it's solid and ready for reliable use. You should run Memtest whenever you install new memory or if you have doubts about your memory not being stable, ie: causing system freeze/crash, etc.
@KimCheeHuu My MBP does seem/feel to run a bit smoother with 4GB.. I definitely see Less of the progress spinning wheel overall. I'm sure you'll get even better performance when you install 8GB. The memtest86+ is available from their site. Look in description for their link.
I'm thinking about upgrading my memory on my MacBook pro. 8GB are pretty cheap so might go that route. Has there been significant improvements after u upgraded your Mac? Where can I get memtest?
as far as i know its the OEM ram, i bought the computer used and haven't opened it yet, but i started looking into this because of persistent kernel panics approx 10 times a day
Yeah.. I'd be forced to agree (with that many errors found.) What brand, size/specs is this memory? Hopefully it's not out of a mission critical machine...
@TXcodeDesigner i've recently upgraded to 8gb ram on my MBP i7 and i've been having problems with the filesystem after that. i decided to do a check with mt86+ 4.20, and it found errors. i switched back to my old ram, and it failed on the same memory address (tried to switch the chips around too so it isn't the slot). memtest mac and my service shop can't find any errors. i thought mt86+ would work on all computers with x86 architecture? i changed my hd yesterday, so i'll have to see.. any tips?
A good video in the sense that it made me aware I should test the new RAM I just installed (after having watched your video on that topic). However, it would be useful to have more info on exactly how to test it (i.e. why memtest86 and not something else?), and how to interpret the output of the test results. Your video is very basic, and the memtest86 site is way over my head- I need something for dummies :-) But thanks for the video - it's a good starting point.
Ouch! Kernel panic 10X a day...!?? THAT would drive me up the wall and crashing down the other side! Well, hopefully some new RAM will solve your problems. Just make sure you get the correct DDR type (DDR, DDR2, or DDR3) < They are NOT interchangeable, so be sure BEFORE you buy. Just a friendly heads up.
@OG230003
Yes, however it is highly recommended that you install DDR3 memory sticks to achieve maximum performance.

Many thanks TxCodeDesigner! Thanks to you, I brought my dead Macbook pro to life, after 3 beeps non-start trouble!

I'm trying to run this on a 2011 MBP Sandy Bridge and keep getting 'Unexpected Error - Halting'. It happens almost immediately... Any thoughts?

Solid.. Glad it helped. Please remember to rate & subscribe.

A little shaky but a nice tutorial for memtest86+. Thumbs up
It may be a stupid question but which version of memtest do I download from their website?

It's ready for memorys DDR2 and DDR3? thanks
Any brand/website recommendations? The only place I know to look is mac sales .com
i like it :D thx

So if I run this for 5 minutes and get 47,000 errors....chances are its time for new RAM right? hahah
