So hardware it was.

These problems are hell to find. I once had to disconnect the power on and reset buttons from a case to a motherboard after weeks of problems. Annoying to have replaced the motherboard first. But memory drifting out of spec is notoriously annoying.

You may find that any 2 sticks work but all 4 won't or some combination. I have one computer running with 3 sticks (on win32 fortunately) because I didn't want to replace the ram and 4 sticks kills it.

You get the idea though ... in the end just buying 100% new ram may be simplest.


Still testing one DIMM, three to go...

A couple of years ago I had a problem similar to yours with my previous computer. For example, if DIMM A was in slot A and DIMM B was in slot B the computer didn't recognize that B DIMM, it would say that I only had 2GB, but if I reverse order, DIMM A to slot B and DIMM B to slot A that second DIMM would be recognized and I would have the 4GB that I was suppose to have. Why that happened I have no idea but it completely drained my energy trying to understand what was happening.

The same with Sierra. How could I accept that I had a memory problem when Multicharts and Investor RT are able to load more than 20 charts at the same time and the computer runs as usual and every time I would load charts using Sierra my computer crashed. For me this was obvious a Sierra problem.

... and what I was afraid of is turning to true, I'm testing the fourth DIMM now and none of the tests crashed the computer so far.
The test ran for one and a half hour for each DIMM.

Next stage will be testing 2 DIMM's together.

How can a guy understand this.

Prime95 didn't find any error testing each 2GB DIMM's. Opened Sierra using each DIMM, open3d 4 chartbooks at the same time, 20 charts, not once it crashed. Started to connect the DIMM's together, one by one, always testing Sierra, opening those 4 chartbooks, not once the computer crashed.

Now I'm testing again using Prime95, all 4 DIMM's connected, so far didn't crash.



What can a guy do in such situation? Seriously, what can we think in such situation?

Interesting.

It could have been a loose connection on one of the DIMMs, or just the ordering change somehow solved the issue.

I would definitely let the custom prime95 test run overnight with 4 DIMMs. Change the time from 15 minutes down to 5 minutes, so that it can complete a cycle in about 6 hours instead of 24.

But hey, problem solved! Now welcome back to using Sierra!

Just noticed something strange



3,99 GB usable?

Where are the other 4GB?

Interesting.

Try this:

Run MSCONFIG

Check to see if selective start is selected.

If yes, go to the boot tab.

Click "Advanced Options".

Deselect the maximum memory option if it is selected.

Also, you can optionally select the number of processors to increase the boot speed.

Click on apply to apply the new settings.

Reboot the computer. Once the computer is rebooted, right click on "Computer" on your desktop and select properties. Installed memory should now show just the memory installed rather than the 2 components (installed and usable).

Also check here:

The usable memory may be less than the installed memory on Windows 7-based computers

Specifically, BIOS settings for Memory remapping.

Actually it continued the same.

Guess what! I reversed the DIMMs order and now I have the full 8GB available.

Go figure...

At least, so far, this order reverse isn't making Sierra crashing the computer again

You have 4x2GB DIMMs, right? Are they all identical make/model?

You have 4 DIMM slots, or 8? If eight, there are blue slots on the board [probably] that you need to install in, and skip the black ones.

I have 4 slots.

All DIMMs are the same model and make, GSKILL PC-3 10666 4GB ECO CL7 DDR3. The only different between them is the fact that initially when I assembled the computer I only had 4GB (2 DIMMs). I bought the other two 6 months later.

Never noticed that when Sierra is loading the charts it makes my CPU go to 100%. Multicharts and IRT rarely move my CPU above 50% when loading them.
