Now that we're well into Autumn over here in NSW Australia I decided it was time to tighten the living s##t out of my memory modules (CMK16GX4M4B3000C15). After 2 days of tweaking/testing I reached the following timings:
And here are the benchmark results:
After updating the mobo's BIOS to the latest revision, the PC couldn't complete POST.
I Added 10mV to RAM; POST now completes, but there are errors during test 7 of memtest.
Changed tRFC from 300 to 304; errors don't occur until test 13.
Changed tRC from 8 to 9; no errors after 4 passes.
Subtracted 10mV from RAM; no errors after 4 passes.
Played with a few timings and managed to reduce tWTR from 4 to 3. I also set tCKE to 8 (about 5ns).
Here's the (best of 3) benchmark results:
C-state 1E was enabled; maximum "North Bridge Clock" is actually 3602.1 MHz.
The benchmark in the original post was best of 3, so I may have actually gained a negligible boost to throughput; likely due to the reduction in Write-to-Read time.
Anyone else able to reduce their tRAS and tRC this much?

Obviously I wasn't paying attention when I took that screenshot. :facepalm:

In case you've missed it, this post -> [thread=148427]Memory overclocking[/thread] <- contains some info on operating voltages; scroll down to "ISSUE #3: General behavior of various IC" and there you'll see quite a range of voltages were tested. Find out what IC your sticks use and you'll have a good idea on what voltages you can get away with.
