Hello,
i own a xw8400 and want to use 4x8GB memory modules.
I bought 64GB (8x8GB) DDR2 FB Fully Buffered PC2-5300F 667 Memory and they are accepted by the system.
But - after some time the computer goes down / is switched off. There's no bluescreen or other hint helping to find the cause. The machine is switching of like pulling the power cord.
At first i thought it might be a cooling problem. So i checked the temperature and it seems to be in regular limits (about 28-30°C air temperature).
I found info in the web, that 32 GB on that machine (2 CPU) should only be possible with a riser card (8x4GB). On the other hand it might only be a result of the fact that 8GB modules were not available at this time.
I have two questions:
* Is it possible to use 8GB modules on a xw8400 system with 2 CPU?
* i am currently testing the modules with memcheck but is there any way to get diagnostic information why the system is shutting down?
Thx G.
