Ram OC questions.
Ram OC questions.
I'm using a PC with these specifications:
ASRock H370 Pro4
Intel Core i5-9400F
16GB (2x8) Crucial Ballistix Elite DDR4 - 2666Mhz - 16CL
I found out I can adjust my RAM's timings and voltage in the BIOS (version 4.10). I'm currently attempting to optimize my RAM. I understand the board caps me at around 2666Mhz, but I'm trying to push lower timings. The default RAM settings are 16-17-17-36 2T (1.2V) and I've already optimized it to 14-14-14-35 1T (1.35V). The question is whether I can reduce the timings further, such as to 12-12-12-32 1T (1.35V/1.4V)? Would that be feasible? And would it be safe for continuous use?
Run four passes of memtest86 to ensure the stability of a RAM timing change. I experienced unstable RAM that failed short prime95 and aida64 stress tests. A suitable quick check involves downloading the Ryzen DRAM Calculator 1.7.0 and performing a full memtest at 600%. You can also perform four passes of memtest86, which will take over two hours. Longer testing periods may lead to errors, which is why ECC RAM was developed to minimize such issues. It’s best not to see any errors during testing.
So my board restricts me to only 1.35V, but as I adjust the timing settings it's improving. What I've managed to do:
XMP Profile 1 > enabled
(1.2V) > (1.35V)
(16) > (12)
(17) > (12)
(17) > (12)
(36) > (28 [lowest possible for my board])
(2T) > (1T)
All other settings are set to Auto.
I've been running AIDA64 Extreme stress test for about an hour and everything was fine.
I also tried Prime95 stress for an hour, everything worked well too.
Lastly, I used memtest with just one pass and it passed without any issues. Here are some screenshots:

My RAM is now running 12-12-12-28 1T.
Would you think it's stable?
Should I try to lower the timings further, would that be worth it?
Should I adjust any other settings? In the dramm configuration tab there are around 100 options with different values.
Is there any risk involved?
Run four passes of memtest86 to verify that a RAM timing change remains stable. I experienced unstable RAM that failed short prime95 and aida64 stress tests. A suitable quick check involves downloading the Ryzen DRAM Calculator 1.7.0 and performing a full memtest at 600%. You can also execute memtest86 for four passes, which will take over two hours. Longer testing sessions inevitably lead to errors, which is why ECC RAM was developed—errors should be extremely rare. It’s best not to see any errors at all.
