Ok. So I have already completed the upgrade although it didn't go exactly as planned.
For the GPU, I didn't encounter any problems. Everything is working as expected.
However for the RAM, my initial plan of
2 x 4 GB XMS 3 didn't work (in addition to my initial 2 x 2 GB XMS Config).
Unfortunately, I didn't have the foresight to bring the manual of the MOBO at the time of the install to diagnose using the beep code.
I had it installed in a shop (too paranoid to do tinker with the hardware, still have to learn more).
We tried different configurations:
Config 1: 2 x 4 GB + 2 x 2 GB = Did not work.
Config 2: 2 x 4 GB = Did not work.
Config 3: 1 x 4 GB + 2 x 2 GB = Worked.
Config 4: 4 x 2 GB = Worked (My current config).
What I'm wondering is why didn't the first 2 configurations work?
I'm a little stumped. The board specs indicated that it can support 16 GB of memory but could not handle 8 GBs?
I tried scanning through the manual and the specs of the memory but could not find the reason why it didn't work.
Anyone has any ideas? Just something to start my search on. I don't know where to start.
I can't change my current configuration anymore but I want to know the cause of the problem so I don't encounter it again in the future.
(I plan on making a new rig in 2 years)
