A new workstation has been built on a remote-site but we’re having trouble getting the memory working.

Build information:

Simulation application crashes under load when all RAM was installed. When memtest was ran, it failed.

The test passed only when installing four slots. With 6 or 8 slots populated, memes failed (we didn’t try 1-3 – see picture below).

When replacing with the other 4 memory modules, they also passed memtest, so we concluded that the memory modules are all OK.

Anybody else had any forms of compatibility issues with these products? Or know of any specific settings needed in the BIOS that we are missing?
