[Sammelthread] Ryzen RAM OC + mögliche Limitierungen

[Tatilica]

Thanks for the answer! It just didn't work with 950 mV VDDG IOD. Sometimes it works, sometimes it doesn't. That's why I'm now giving it up to 980 mV with a clear conscience. Keep watching the thread in case anyone has a different opinion...

You are fine, nothing uncommon for X 3000 or 5000 series VDDG goes 1.005v manually dif. mobos B550

Even higher VDDP 1.005 VDDG 1.050 for X3D keep up running 4x8gb Vipers in sync channel A/B tphyrdl 26/26

Eben weil man beim RAM OC in Games eher weniger rausholt, habe ich mich davor bisher gedrückt und auf die CPU und vor allem die Grafikkarte beschränkt. Beim RAM OC hatte ich bisher nur XMP aktiviert und vllt. noch einen etwas höheren Takt mit Command Rate 1T und ein bisschen höherer VDIMM eingestellt. Mehr hatte ich nie gemacht, bis ein gewisser Tanzmusikus im computerbase Forum, mein Interesse geweckt hat und mir viele Tipps gegeben hat, danke dafür auch nochmal an dieser Stelle!

Was RAM OC konkret in Games bringt, kenne ich an guten Videos nur dieses hier. Besonders die 0,1% min. FPS und die 0,1% max. FPS profitieren davon. Es gibt natürlich Spiele die mehr, und welche die weniger von schnellerem RAM profitieren. Bzgl. synthetischer Benchmarks kann ich z.B.: folgende Ergebnisse von meinem System posten (schneller ist besser):

Spoiler

2133 JEDEC (default, no XMP)

3600 XMP

3600 tuned subtimings

3666 tuned subtimings

3600 sharp subtimings

3733 sharp subtimings

Ich habe mich auf die subtimings spezialisiert, weil der Memory Controller meiner CPU nur bis 1833 MHz IFCLK (3666 MHz DDR) sauber/primestable geht. 1866 MHz IFCLK (DDR 3733 MHz) bekomme ich nur Benchstable, nicht primestable und IFCLK 1900 MHz (DDR 3800 MHz) geht gar nicht. Ich verwende das Setup "3666 tuned subtimings" für den täglichen Gebrauch, da die Settings/Spannungen mir sonst zu ungesund werden und der zusätziche Performance Gewinn nur gering ist, im Verhältnis zu den dafür notwendingen Spannungserhöhungen.

Thx your input @Tatilica

Impressive results, but at the cost of unhealty voltages. Although i'm not an expert, I wouldn't keep these settings, if you want a long live system for many years. No matter if temperatures are ok on the chips, the problem mostly are voltage converters and capacitors. For example the daily setting i use:

Before i've even used only the 3600 tuned subtiming setup for "daily usage", which is only roundabout 3 seconds slower in the Membench from DRAM Calculator, as seen in my last post.

From what i've read, also the VDIMM has an effect on the IMC, so i wouldn't raise it above 1,45V for daily usage - no matter how good your cooling system is. Althoug i'm a "RAM OC Noob", i've been overclocking CPUs and Graphic Cards since 1998 and i can tell you: voltage converters and capacitors are the problem, even if your temps are OK.

Thx for input, all fine with my settings, cause hope to last forever, already solded as a gaming system and decided to swap on next Gen AM5, good luck!
