Hey guys!
I woke up this morning and booted my (08)mac pro only to find 4GB of ram being booted up on riser B, and my riser A didn't register the other 6GB.
I started to troubleshoot the problem by testing to see if it was my RAM that had a problem, or the riser card itself.
Config; Riser A - DIMM 1 (2GB), DIMM 2 (2GB), DIMM 3 (1GB), DIMM 4 (1GB)
Riser B - DIMM 1 (2GB), DIMM 2 (2GB), other 2 DIMMs empty
Troubleshooting all on Riser A
I started by switching out the two 1GBs, booted, system showed that my Riser A DIMMs 1 & 2, registered, but only 1GB each instead of 2GB.
I then proceeded to switch the 2 1GBs into riser A DIMM 1 & 2, and the 2GBs in riser A 3 & 4. Didn't register any of the mem modules.
I then took 2 x 2GBs from the riser B and replaced it with Riser A's 2GB modules, then i switched the riser Cards themselves. viola! 10GB showed up.
Throughout the whole process, i noticed that when the memory modules don't read, there is always a RED LED on the mem module itself that lights up. So now i'm wondering what is the problem that is plaguing my memory cards? I might add additional ram some time soon and i don't want these problems to happen again.
It's strange at times too, whenever i get a Kernel panic, and i reboot, instead of 10GB, only 8GBs show up, and when i reboot again, 10GBs show up.
This memory problem is starting to concern me.
The only conclusion that i am able to draw is, perhaps one of my Riser cards is spoilt, and should i send it for repair? I am using 3rd party RAM, if i send it with my riser cards, it will void my warranty with apple, yea?
Thanks for your help in advance!!
Cheers!
