I wish to piggyback on this discussion on Z400 cpu upgrade.
I have a version 1 (4 DIMM) z400. The mobo haqve problem and I bought a replacement version 2.
After reconnecting everything back, I got the 3 red LED flasg error indicating that there is an issue with the cpu module. I have reseated the cpu a couple of times but still have the same error. So the mobo could be an issue but seller reassured me that it works fine. I incline to think that the cpu may need to be replaced (already 7 years old).
So it looks like I can opt to change to a highere performance hexacore Westmere (instead of sticking with quadcore Nehalem).
Can I use buffer and unbuffer dimm for this setup? Currently I have a twin 4Gb ram sticks. I am looking to put a couple more sticks- can I use unbuffered ones, considering the existing ones are buffered?
Thanks.
