Easy to use. Can find RAM problems that Apples own software can't.

OWC directed me to use this app after I purchased memory that turned out to be defective. 8GBs took a lot time to go through, but having the diagnostic made exchanging the RAM painless. OWC is great anyway. Since Rember is free, doing what it needs to and getting out fast, I have to give it 5 stars overall even though it looks ugly (which is fine—even preferable to a pretty app that uses more RAM than it needs to.)

If I could add one feature, it would be a loop completion estimate and a total test time estimate. (i.e. “Estimated Total Time: xx:xx” “Time Elapsed: xx:xx” “Estimated Loop Time: xx:xx” “Current Loop Elapsed Time: xx:xx”) This would save everyone who uses this app from having to come back and check every 15 minutes on tests that can take hours.

To the Dev: Thanks for making this app, it does just what it needs to do. You might want to mention that multiple loops will make it so all memory is tested (if the comment below is true) and offer people the option to quite all apps and even the Finder temporarily to free up RAM.

It should be made clear that this app can only test the RAM that is free when it is executed. I need to check if my RAM is defective but this tool only checks the RAM that is free so basically this app is not suited for this test.

Please feel free to correct me if I am missing something here.

There is no app that can test RAM that is currently being used by another program - it's just not technically possible. Seems disingenuous to give this program such a low rating based your misunderstandings.

Thanks for updating the unique+good memory test app !
HINT: PPC User should first try 100MB (not all available ram) to see how much time your whole RAM (500M++) needs. On fast Intel Macs you get an speed from 20-35 Minutes for 2 GB RAM (=3 GB installed). PPC G4 will take > 30 Min for 500MB!!

Just to update with another system:
- MacBookPro 6,2 (i7 2.66GHz) took 53 min for 6713MB (all available; total 8GB).

Thanks for this app, very useful if you update memory imho.

0.3.4b Worked flawlessly on my G4.
Nice output and simple.

If you buy new RAM or used this is the utility to have installed to test
it. Don't waste time with RAM when you buy it, test it ASAP and get
your $'s worth. I've been fortunate to never have had defective RAM, and
testing it just confirms it. I'm happy.

I really appreciate Rember. I got me out of, what seemed like, a hopeless problem with my Mac.

The newest version of Rember (0.3.4b) includes a memtest executable that is more compatible with 64-bit Intel based machines. This should eliminate crashing and slow testing on Apple's newest hardware.

I am very grateful for Rember and Memtest, and only want to help improve them.

It would be very nice if the memory test would permit different ranges of memory to be tested sequentially (or by some other algorithm that covers the entire memory range). If this is already done, then, in the immortal words of SNL great Emily LaTella -- never mind!)

Thus before each test a different memory range would be allocated and locked in, which would slow things down a bit. A possible algorithm for 2 GB RAM, where (say) only 1.5 GB can be tested by Rember, would be to do #1-to-#1.5GB on the 1st pass, #1.5GB-to-#2GB and #1-to-#1GB on the 2nd pass, etc.

Does it tell you that your ram is bad by freezing up your mac and forcing you to do a hard shut down? Or is that it's way of telling you Rember/Memtest itself is bad?

Please provide more information about the crashing that you are experiencing:

Machine type (ie. G4, G5, Intel)

Operating system version (ie. 10.3, 10.4)

Amount of installed memory

At what point is the program freezing? Does it freeze on launch? Does it freeze once you've started tests?

When Rember found a bad stick of RAM, I guess the RAM was so bad that a kernel panic and crash resulted. But after I figured out which RAM was bad and removed it, my system was better. Rember was able to test the remaining RAM without crashing.

I downloaded Rember in order to help diagnose an on-going kernel crash problem. It definitely helped me!

Version 0.2.3b of Rember is compatible with the G3 processor. I would recommend using it. That version can be found at www.kelleycomputing.net/rember.

You can dl the orig. memtest 411 and copy the g3 build into the same place in rember.
orig. 411 memtest has all builds, but have problems to use the G3 one.
This happen to the gui also.
With this way, memtest (with rember) works with the new memtest 411

I have posted a version of Rember that includes the alternative memtest executable (for systems lower than 10.3.9 and G3 based machines) on the Rember download page (http://www.kelleycomputing.net/rember).

useful when you get a kernel panic and dont want to wait through the hardware test on the OSX cd to confirm that it is bad ram.

running rember should be the first thing you do after installing new ram.

aspilian had trouble on 08 Feb 2012
hi,

in the last 5 months, my iMac (i5, 3.6 GHz, 4x2 GB RAM) four times died, beeping like Apple describes in
http://support.apple.com/kb/HT2538
(3 successive tones, a 5-second pause, 3 successive tones -- RAM does not pass data integrity check)

First time I thought corrupt video/cut data were causing the crahs, but not for crash no. 3 and 4.

I let Rember do 8 loops of checking all my memory, with a result that no errors could be found.
Apple Hardware Tests also say that my hardware is okay.

Can you give me a hint how to try to find out what's causing these crashes?

I removed all the RAM and put it back using different slots. Maybe one module was loose??? Don't know...

Zackinthebox had trouble on 26 May 2011
I've got 8 GB of ram installed on a new 2011 i5 iMac but the test log shows that it's only checking 6331 MB. Is this normal? I've clicked the option to allocate all ram for testing. The pop-up window that comes up when you launch Rember shows that I have 4 x 2 GB sticks with green lights next to all of them.

Why does my CPU temp shoot over 125 C (according to iStat Pro and SMC Fan Control) when running the memory test? This can't be safe! I have a Macbook Pro running Leopard 10.5.4.

When processor activity is high, the temperature of the processor increases. This is normal behavior in all computer processors. If a cooling mechanism in your computer fails, the temperature increase may be problematic, but for most machines the increase in temperature should be harmless.

mac adam had trouble on 01 Nov 2007
When I test all memory, "NOTE: Memory request is too large, reducing to acceptable value...", I have a error in Block Sequential ?

No Error when I test less memory…

Is it a Bug or my memory ?

Defective memory can cause computers to malfunction, crash, and behave in a variety of ways which can sometimes baffle end users and computer technicians alike. Apple provides hardware test CDs with most of their products, and there are some third-party utilties for Mac OS X which perform memory testing. In my experience, these tools have not always been able to quickly and efficiently diagnose memory problems. Rember has been designed to simplify the testing, and diagnosis of these problems.

This software is free, and is covered under the GNU GPL. Please read accompanying "COPYING" file for more info.

Features:
  • Easy to use testing console
  • Human-readable test report summarizes test results
  • Memory information window displays DIMM status
