OK, the issue with my CPU/NB voltage keeps rearing its ugly head, I just wish that I had the ability to set it manually in BIOS.
Anyway, decided to go back to basics again and start with my RAM to see what it had to offer.
It has three profiles that are associated with it for "enthusiasts" all at 1.5V
6-6-6-18-27 at 600Mhz clock or 1200Mhz DDR3 2T
7-7-7-21-33 at 700Mhz clock or 1400Mhz DDR3 2T
8-8-8-24-36 at 800Mhz clock or 1600Mhz DDR3 2T
These were all set with 160NS TRFC as it was on auto
These are not the JDEC profiles these are the extreme profiles
It successfully booted and played games when set to 1.65V at:
6-6-6-18-27 at 667Mhz clock or 1333Mhz DDR3 1T
7-7-7-21-33 at 800Mhz clock or 1600Mhz DDR3 1T
8-8-8-24-36 at 890Mhz clock or 1790Mhz DDR3 1T
These were all set with 110NS TRFC as set manually
I have it set currently at 1760MHz just backed off a bit from its maximum at 8-8-8-24-1T with a TRFC of 110NS, around this level seems the sweet spot.
I think this RAM wasn't far off being binned with the 1866Mhz RAM at cl8!
This is with the CPU/NB at 3080Mhz and the CPU at 3.96Ghz, the seeming limit for my CPU to be 100% stable.
After an hour with OCCT linpack!!
Here are the MAXXMEM and AIDA Benchmarks:
