Zenith Extreme wont boot @ 3600

[lilmidnit]

I have F4-3600C16D-16GTZR. DOCP see's it properly and makes the "proper" adjustments...except it will not boot without significant changes and I still have not been able to get it stable in Windows at 3600. If I use the DOCP settings except change it to 3433(or is it 3466?) and it runs great.

Anyone else have better luck? I am using the public 0902 bios

How many sticks of ram are you using?

If you can boot at 3466 consider yourself lucky, most people can't boot past 3200.

In my experience this happens because bios settings are not properly set, expecially LLC 1/ 2. Vboot ram ab,cd voltage "depends on ram banks but if i'm not wrong you have g.skill" and most important..... timings...

do a overclock based on "suggested standardized" profiling like DOCP is not a good idea.

AMD architecture/hardware is not simple/child'ish like intel that you can buy on high specs/numbers and everything works out of the box.

in fact i run my sys on 3600 24/7 cl 14-14-14-34-48 T1 v.1.4 auto ohm.

but you have to experiment with settings. "without exaggerate on voltages" and not with the profile provided by asus.
sometimes you have to buy inferior stock speed to achieve superior timings and speed.

my conf.

threadripper 1950x @ 4.2ghz v 1.26500 llc auto "some llc settings when the cpu are off load causes some electrical spikes even on ram banks" it's not good.

I am using 4 sticks.

I recently tried some hynix (corsair) running at 3466 and C16. Settings are the same as the samsung b-die but every single benchmark is consistently and notably faster. I have swapped several times comparing differences. At this point i have given up on 3600 since I am getting noticable speed difference even with the hynix at its rated 3200 vs 3466 on the samsung bdie.

3600MHz is big ask from Ryzen/Threadripper IMO. I reckon 3333/3466MHz is about it and depending on HW samples this can not be a "plug & play" experience.
