i need help with Overclocking F4-3600C14D-16GTZNB

[Mr4nT4r_KSA]

I need help tightening my RAM

 

CPU: 3600 @4500 1.337v  (r7 5800x is on the way)

MoBo: TUF GAMING B550-PLUS, BIOS v2423

RAM: 16GB (2x8) G.Skill F4-3600C14D-16GTZNB 3600Mhz 14-15-15-35 stock @1.45v

Try aiming for 4000 14-14-14, ryzen doesnt really go that high on rams due to the infinity fabric so best bet is 4000 14-14-14, b die does like volts so dont be afraid of pushing the volts, max safe is ~1.7v

so i should try 14-14-14-? and the rest leaving them to auto right?

You can just leave them at auto but it may be worth tweaking the other timings, aim for 3800 or 4000, though if your cpu can do higher then why not

by tweaking other timings you mean reducing the numbers right? like how much should I reduce?

Well thats just trial and error, reduce 1 step at a time and keep reducing till unstable

 

Personally i use prime95 large ffts for ram test

 

Tbh i can only give you general info, youll want to look at some yt tutorials and maybe have a look at actually hardcore overclocking aka buildzoid cause he does heavy tuning to his rams but after youve watched some tutorials just to give you an idea on the basics of ram oc

what do you thinks about this test?

Welp looks pretty good timings wise

What volts are you running anyways?

1.5v for RAM and 1.188v for cpu @4200Mhz

Well its b die so i can reccomend a max safe of 1.6v and if you are ok with taking risks absolute max 1.7v

can i go lower than 63ns ?

If you just leave your subs on auto and crank the fclk and mclk it will just raise internal timings and slow things down, a bit counter productive. 2K and flat 14s is a pretty tall order.

DDR4 RAM OC'ing Guide.

I suggest you read THIS if you want to dive into advanced level DRAM overclocking.

I tried 4000MHz with loose timings @1.5v  but no luck

What RAM chips/dies do you have?

Ah, I might have missed that they are obviously Samsung B-die.

could be my limitation be Motherboard or CPU? since the RAM is a really good one

Motherboards imo don't really limit OC, rather CPU integrated memory controller.

In case of AMD it's the latter for sure.

If the motherboard has poor trace routing, poor EMI / noise isolating, then you'll achieve a lower DRAM overclock. But that is usually only a problem on budget motherboards (i.e. B450, A520, etc). At that point, you are shooting for DDR4-3600+ on those boards....more like using DDR4-2933 ~ 3600 only.

 

The ASUS TUF B550-PLUS is "rated" by ASUS to go up to DDR4-4600+, packing 2x 50A  power stages for the SOC.

 

Your weakest link would the the CPU (e.g. IMC).

For Ryzen 3000 / 5000-series, you are limited to around ~1800 MHz FCLK, on average (= ~DDR4-3600).

AMD mentioned Ryzen 5000-series can maintain 1:1 up to 2000 MHz FCLK (= ~ DDR4-4000).

You want the MCLK and FCLK to be 1:1.

As soon as you over-step, and it is NO LONGER 1:1 (e.g. MCLK:FCLK = 2:1), you'll see a significant latency hit.

Before I left my house, I checked memtest64 and it's been ruining for 9hrs (the memtest64 still running)
it's running 6 threads each about 1700MB and it reached about 2000% for all 6 threads. only one thread got 12 errors and the first error was at about 70%

 

I'll post a picture when I reach home.
