Timings
Good day, I bought RAM 16GB ddr4 2666 kingston renegade, and decided for the first time in my life to get into the BIOS and adjust the timings, please tell me, as the most incompetent person in this matter, is it normal for me to set the timings for this RAM and is it possible better. And about the voltage, leave the stock 1.2V or raise it to 1.35V and what does it affect?

the same sort through the secondary. There will be no miracle with such a memory. Test the stability, don't forget, at least go ahead and run it for 30 minutes. In general, there are a lot of guides about overclocking.
VCC io / sa - no more than 1.25, ideally 1.2. DDR V - 1.35 is more than normal. Within 1.4 you can safely keep. And even become impudent up to 1.45. Above - for this memory no. Samsung and work on large ones. VOLTAGE affects stably in overclocking. But it also has a big effect on the temperature of the dies. Without raising to 1.35 you will not get stable 3200-3600. Also, as far as I understand, high voltage allows you to reduce timings.
Find me: 
Or Dakar a. Although, you can order (buy) from him.

Otherwise, it is possible for more articles on overclockers. There are a lot of the same. Do not forget to look steadily, otherwise they will stick. Leave the voltage.
ZY, so that you understand. Samsung 3200 C14 (set 13th). You have 2666 C13. But memory chips, as I said, are kingstones, rubbish - don't expect a miracle there. But now it doesn't matter, there won't be another.

I put up the secondaries, it turned out to put CL12 12-15-15-30. But the latency remains 54-55, it can't be lowered anymore, what else affects the latency? And for some reason, the memory and processor frequencies are not stable for me, in the BIOS you can see how -10mhz + - jumps, and the voltage jumps a little on the memory and processor
01001000 01101001
Or at this frequency 53-54 latency is the maximum that can be squeezed out

Latency - processor overclocking, command rate, RAM frequency, timings (primary, secondary and tertiary), memory chips, processor controller.
processor frequency - power saving mode. There is nothing more to be done here, neither the percentage nor the overclocking board and fixing the frequency can.
And that's how the memory frequency is unstable. Units are the norm. No longer. 2667 in the benchmark let's go. so be it.
Processor's frequency is a quite dynamic value. The frequency of the RAM is always fixed.
The voltage will change. Vid processor - the value requested from the motherboard. Vcpu is the answer to this value. It will change and adjust, depending on the frequency and load. Operatives can do the same. Frequency +/-10 is quite normal.
This system is not about overclocking. There will be no miracle. You can still try to put CR1. But if the chips are rubbish, then it is unlikely.

A carrier with an axis does not affect latency at all? And then the ssd is far from fresh, like the Windows that was installed on it 3 years+ ago
01001000 01101001
with CR1, the latency has become slightly better. But the frequency is constantly changing in the RAM, then 2650 then 2666, it jumps within these limits. There are also a bunch of settings in the BIOS like realtime memory timing about which there is no information at all.

realtime memory timing is so that you can configure it from under Windows.

Minor programs in Windows reduce latency, but here it is worth clarifying - a lot of running ones. So, do not load the opera, I'm testing it on a cold one, once (the second run and subsequent ones, without rebooting, are false). In general, if Windows does not have critical errors, let's say such a joke was in Windows 11, then no. You don't have the same problem. The SSD has no effect either.
CR1 / CR2 yes, affects stability. I can’t understand one thing - you poke, but you run the tests on stably. If the memory took and works, then order. Usually CR2 on bad chips is overclocked, set for stability.
01001000 01101001 Are any
of the secondary - tertiary parameters particularly important? I didn’t touch the tertiary ones at all, so I think it makes sense
... my opinion, do not overclock, leave it as it is, you will not notice a tangible increase ...

Among the secondaries, you can try to reduce tRFC. I have 584 ns by default, I set 520 ns.
Denis Kyokushin
Have you seen people reduce tRFC up to 200, did you notice noticeable changes?
I have 460 by default tRFC
In general, after setting all the secondary and tertiary timings, we managed to drop the latency to 50-51, maybe someone will need it with a similar memory - chips.

Testing Changes:
Assassin's Creed 3
Assassin's Creed Unity
Far Cry 5
Do you have Denis Kyokushin CR 1 or 2? And tested whether the difference. And m2 affects significantly in games relative to conventional ssd?
