Yes it 4 x 4GB Kit....I have ensured proper "seating" of RAM, hell if I "seated" it any more firmly and squarely in the Sockets I'd drive it right through the Mobo
😉OK, so here is what I did (further to what I Posted earlier):
1. 1 Stick in DIMM Socket D1 - Post fine showing 4GB
2. Moved that same (know its working Stick) to DIMM Socket B1 - Post Fine showing 4GB
3. Moved that same working Stick to DIMM Socket A1 - Post Fine showing 4GB
Now:
4. Moved that same working Stick to DIMM Socket C1 - NO POST DEBUG Code 53 (Memory Error)
5. Tried my other 3 Sticks in DIMM Socket C1 - NO POST DEBUG Code 53 - same thing.
As my testing above in previous Post, all was good up to 3 Sticks - Posting with 12GB, as soon as throw another stick in DIMM Socket C1, yes it will Post, but only 12GB, take out the Stick out C1 and STILL 12GB.
Now, I have built a number of Rigs over the past 7 yrs, have never had to troubleshoot Memory to this extent. (lucky I guess), But would folks hee concur that I have a faulty DIMM Socket C1?
Not using a Noctua NF F12 Cooler, its a Corsair 100i with Noctua NF 12F Fans mounted on the Rad.
Now I did tighten the heasink / pump assembly of the 100i down pretty hard, (same as I did on my Classified 759 Board), but what I'm going to do now, is remove the heatsink, inspect the Socket Pins and reinstall Heatsink with a little less pressure.
If that doesnt "cure" the problem, I'm stumped, other than RMA the Board.
Thoughts guys...cheers n thanks for the support.
