I never knew you could set tWRWRSC/tWRWRSD and tRDRDSD/tRDRDDD to the same value. Everything I've seen always has them varied by 2. 7/7 5/5 or 6/6 4/4 or 5/5 3/3. But then I looked at the preset on the CH7 for 3466MHz and it's set up as 4/4 4/4.

despite what dram calculator says no way any rec,alt,alt2-3 work. Either NO POST yellow dram light or restart from prime95 after 2-4h with yellow light

I started challenging the common settings, in groups

Clkdrvstr, addcmddrvstr, csodtdrvstr, ckedevstr,
rttmom-rttpark (rttwr disable) and bus timings
Higher voltages
Lower voltages

skip ahead 7 days of testing, cad bus block drvstr ohms are too low. 3600mhz 60-60-60-60 ohms, 3533mhz 40-40-40-40 ohms.

Even if 3600mhz fails its shown much more stability. I'm already 50mins into prime95 while 20,24,30 ohm would fail first 10mins

I'm sure this has been asked before, but I can't find it in search and it's a really long thread to look all the pages.

In the first post there were 16 threads of memtest with 850mb each = 13600mb total memory. If I have a R5 2600 and 16gb ram, should I use 12 threads with 850mb each or the amount necessary to get 13600mb used in total (1133mb)?

Same amount of total memory just divide by 12 instead of 16 (850mbs per is what I use on my 2700x).
Thread count to match number of instances of MemTest, each instance to run with equal amount.

Running at 1.4V, tightened what I could. Tried 3533 and it spits some errors, sometimes after 6000% in RAM test. Disabling Geardown mode is a no-no on this CPU, and it doesn't like tRCDRD at 14.

I got the geardown mode on just will bypass some tightened values making it pointless, or am I wrong?

It overwrites the command rate, even if I don't exactly know how it works. I don't really have a choice, if I disable, I get a crazy amount of errors. My R5 1600 was fine with it disabled.

Enabling GearDown can work wonders for OCing ram. Some ram need it enabled, some doesn't

It really doesn't impact performance - one of my fastest profiles runs with geardown on.

Ok, I will give it a try ..... I only care about latency, see if it will in the end be a salvation for the 3400 fast profile I'm trying to stabilize for hunt showdown

I always recommend to people having trouble reaching or passing 3200MTs to enable GearDown. It might not work for everyone, but I think for most it allows higher clocked ram. Worked wonders when I had G.Skill memory.

I have it disabled since my modules were more stable at 1T.
I've just got new Patriot Steel 4400s - they don't need GearDown enabled so far - I'm running them at 3600CL14 currently. I'm hopeful that when I have problem getting them faster, I'll still have geardown in reserve to push them a bit further. I have booted these at 3866 T1 GearDown off but it wasn't useable. My old G.Skill 4233s had to have it on to get 3200MTs or higher...

Now I have 3600 working well I'm going to try pushing them further :)

You could try tCKE at lower values next since you're using GDM. Try going to 6 and if that works well then try 1.

Last overclocking before 3800x
Ummmmmm wut.

How many tries to get through one Aida bench?

Also, don't forget that you can right-click on Start Benchmark and then select Start Memory Tests Only.
