[SOLVED] Ram wont go to 3600mhz

[Zero420]

I recently upgraded a couple of parts in my pc including motherboard and ram.

Setup:
Ryzen 7 5800x
Coolermaster 750w
Corsair Vengeance LPX DDR4 3600MHz 16GB (CMK16GX4M2Z3600C18 )
ASUS ROG Strix B450-F GAMING II

Now i tried enabling docp and setting it to 3600mhz, yet this failed and it rebooted many times and resulted in it running 2666mhz.
I tried lowering the speed to 3400mhz and it worked without problems. Im running it at the correct timings and voltage.

Is the ram in the proper slots?
Do you have the proper bios?

Try increasing the voltage by 0.005 or 0.007

There would be no D.O.C.P profile at 3600Mhz so the system would attempt to set a safe set of SPD values to enable a Boot at 3400Mhz. (hence the multiple reboots)

You have chosen 3600Mhz OC RAM however your CPUs IMC (Integrated Memory Controller) supports up to 3200Mhz so there is no guaranty you will achieve the rated frequency. It depends on the quality of your chips Silicon if it will scale up to 3600Mhz.

Are you familiar with Flashback that your MB provides for?
First update your Bios to latest version 4602 and at the same time your chipset.
This is to update AGESA and for improved performance.

You may have a better chance of reaching 3600Mhz with a few manual Bios tweaks. Try Increasing Dram Voltage in .01 steps (no more than 1.4V). Set SOC voltage to 1.1V and try command rate from 1t-2t.

Thank you so much. Ill try the bios update, i already tried the dram voltage and soc voltage with no luck.

After bios update it still wont do 3600mhz, i guess ill have to settle for 3400 🙁

Don't concern yourself Zero420 😉 There is very little difference performance wise. Maybe a few FPS in AAA games and benchmarks. Best to have that and maintain stability.

The XMP profile only sets a few settings, motherboard is expected to figure out the rest. First, disable Fast boot. Second, if you have a setting like "Memory Retry Count', increase it to 5 or 7. Gives mobo more tries to find settings that work. It's probably "Mem overclock fail count". XMP is technically an overclock. Page 23 in the manual https://dlcdnets.asus.com/pub/ASUS/...STRIX_B450-F_GAMING_II_BIOS_Manual_EM_WEB.pdf
Sticks in slot 2 and 4 counting from the CPU-slot. SOC 1.1v, DRAM 1.35-1.40v.
And of course the sticks have a 3600 XMP profile.

Officially, the Ryzen 5x series supports upto 3200MHz at the IMC, but realistically I've yet to see a Ryzen 5x that can't use upto 5000MHz, with single rank sticks in dual channel mode.

SoC should not exceed 1.2v. I'd set the DOCP profile, manually change the dram voltage to 1.37v and then hunt around in the OC settings and lock fclock in at 1800.

You can also use Dram Calculator (and Thaiphoon Burner) to dial in the Secondary and especially the Tertiary timings as they have a lot more to do with stability than the Primary timings.

I'd make a factory default, 3400 stable, profile and save that as profile #1. Then make some ram changes and save that as profile #2. Have bios load from profile #2 and keep tweaking, can always change that to profile #1 on boot and be fine. There's around 40+ ram settings, so saving prior changes is advised as you tweak.

My gskill 3600 works fine on a 3700x, but does not like any changes to any of the primary timings, yet loves the dram calculator settings for secondary and tertiary timings. There's an obvious difference in boot timid, windows loads and fps. Having a saved profile means any time I reset the cmos, I always have a good profile I can reload from and not have to reset all those timings from scratch.
