OC Help: I am having issues trying to get Ryzen system stable.

[unseenmorbidity]

System specs:

Ryzen 7 1700
EVGA GTX 1080 FTW2
Asrock Taichi
Noctua D15
Gskill TridentZ 4000
Samsung 850 EVO 250gb

I have had the system stable at 3.9GHZ & 3200 CL14, but the OC I am aiming for is 3466 CL14 & CPU 3.9 GHz.

Current Settings:

CPU:
3.9GHz
1.3685v (I have tried up to 1.4v to no avail)

Memory:
1.4v (I have increased this up to 1.45v, and it didn't help)
SoC: 1.15v (I have increased and decreased this, but it always become less stable)
53.5 Ohm

The system will pass several passes of memtest, but Aida64 will crash within 4 hours.

I tried increasing the tRC & tRAS, but that didn't work.
I tried increasing tRFC to 300, but that made it worse as well.

Anyways, any tips?

For sake of curiosity ... does it crash under regular use, or just when stress testing?

Crashes with Destiny2

Have you tried lowering the voltage?

You have to keep in mind, that using too much voltage as well can cause instability and crashes as well.

Just a note, I have read that with the current Ryzen 3,5,7 CPUs, the relationship between the memory controller and the CPU overclocking, since the CPU has internal capacitors, it can only supply so much max power, so that overclocking the CPU cores to "max", as well as overclocking the RAM to "max", may not be as easily possible, as overclocking each one individually.

This is probably not altogether that different than overclocking higher-end Haswell CPUs, because of their FIVR.

(*) And those parts inside of Ryzen, they might be inductors, and not capacitors, I don't remember exactly.

If you look at Silicon Lottery, only a smallish percentage of 1700s will even hit 4 GHz. So you may have lost the "silicon lottery" there.

Same basic deal with the IMC.

I got soooooo close to DDR4-3600 but I can not make it stable, no matter what I do, on my 1800x. Just off the cuff, I'd say you've done your homework and found your limits. Though I can show you the timings for my b-die and let you try them. I use 1.42v vDIMM and 1.175 SoC voltage fwiw. It's DDR4-3466 14-14-14-28 stable @ 4.0 GHz (when I want it).

Take everything back to stock, then up the speed, and the CPU vcore only SLOWLY.. I think you can get 3.7 or maybe 3.8, beyond that, its the lottery,.

I have removed the CPU OC altogether, and I am still having trouble getting 3466 to pass aida64. It seems more stable, but not completely there. I think if I had to drop the OC from 3.9Ghz 3333 vs 3.7 GHz & 3466, then I would be better off with the 3.9GHz, wouldn't I?

Personally I would go with the higher memory speed. Also check your timings. If you can tighten those up, it will also help.

Did you try with base clock?
Like 103MHz?

OP, try these RAM timings with vDIMM 1.42v and SoC 1.175:

Some of your timings may be a bit off. These work for my DDR4-3733 sticks on an 1800x, and I have the same mobo as you as well. Give em a shot. If those don't work try some of the timing sets that chew* has over on XS.

That link takes me to my dropbox home page. I have never used Dropbox, so I might be doing something wrong, idk.

I have not. What is the number that changes the PCIE to 2.0? 105?

I will look into that, ty.

C6H will maintain PCIE 3.0 up to 104.8MHz over that PCIE 2.0.

Try this one
Base clock : 104MHz
Memory multiplier : x16.67 (3333MHz)
SOC V : 1.125-1.15V (first 1.125V)
DRAM V : 1.425V

104 * 16.67 = 100 * 17.33

Also someone posted DDR4 calculator make sure your timings and V are good to go.

Damn. I need to see what's up there, it may be that DropBox is being hinky about links now.

edit: okay try this:
