Documenting Problems That Were Difficult To Find The Answer To

Bad Memory!

As part of an upgrade to my PC with an Ivy Bridge i5-3570K processor I bought a 4 DIMM pack of Corsair 16GB (4x4GB) DDR3 1600Mhz Vengeance “low Profile” Memory Kit CL9 1.5.

A couple of times in the evening after upgrading my PC I got Blue Screens of Death. Such as the following:

Blue Screen of Death - MEMORY_MANAGEMENT

Blue Screen of Death – MEMORY_MANAGEMENT

This said:

A problem has been detected and windows has been shut down to prevent damage
to your computer.


If this is the first time you've seen this Stop error screen,
restart your computer. If this screen appears again, follow
these steps:

Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer
for any windows updates you might need.

If problems continue, disable or remove any newly installed hardware
or software. Disable BIOS memory options such as caching or shadowing.
If you need to use Safe Mode to remove or disable components, restart
your computer, press F8 to select Advanced Startup Options, and then
select Safe Mode.

Technical information:

*** STOP: 0x0000001A (...)

Collecting data for crash dump ...
Initializing disk for crash dump ...
Beginning dump of physical memory.
Dumping physical memory to disk: 80

A prior Blue Screen of Death (BSOD) mentioned something about a system exception.

After searching the Internet I eventually followed instructions and downloaded onto a USB flash drive the latest memtest86+ program (at The Windows USB installer worked for me.

So I booted into the flash drive which runs the memtest – and immediately started finding errors. So I used the old “binary search” algorithm (where you divide the problem by 2 over and over until you isolate the problem).

I ripped out 2 of the 4 memory DIMMS – and still encountered errors. Then I ripped out one more DIMM. No more errors. Now I knew which DIMM was faulty. I installed that as the sole memory DIMM and re-ran the memory test – errors! This is what it looked like:

Memtest86+ and a DIMM with errors

Memtest86+ and a DIMM with errors

Note that the memory test constantly identifies two upper bytes as faulty – the remaining six are fine – which could indicate faulty chips on the DIMM.

Then I pulled out the faulty DIMM and put in the 3 okay DIMMS. Re-ran the memory test. No problems.

I recommend this approach to solving memory problems. At first I thought it might be a timing issue. Fortunately it is as simply as a faulty DIMM.

2012-05-23 Update

I had, delivered on 2012-05-21, another 16GB of RAM as an 8GB set of Corsair Vengeance 8GB (2x4GB) DDR3 1600Mhz CL9 1.5V Non-ECC (black) and an 8GB set of Corsair Vengeance 8GB (2X4GB) DDR3 1600Mhz Memory Kit CL9 1.5V Non-ECC (red) – both 9-9-9-24.

Of course this time the first thing I did was run a full memtest86+ test set on the RAM. All clear! No blue screens of death in the last 2 days including leaving the system running overnight and various suspends/wakes.

Here is a picture of the red and black Corsair full height memory DIMMs in the running board (the fan appears stopped because of the flash but was actually spinning):
