I did MEMbench and monitor temps with HWMonitor. I think temps are fine.

What do you mean “even more so with AIO”?

thank you

biggest change seems to be in the termination block, im gonna have to try those out to see if i can get 3800mhz instead of 3733 with 4 stick, otherwise my old settings are stable on the new agesa bios still

Why there's no A0 for Micron E-Die?

I really don't understand these craze of OC'ing stuff . All you get is bragging rights and thats;s about it.
OC videocard - 10 fps more
OC proc - I don't think you gain anything .
Oc ram - 3 - 5 fps more.
that's about it. ...
I done stuff like this in the era of Pentium 1 and Pentium 2 .... going DDR1 from 266 to 330 if I remember right. In that period of time it was more then worth it ... now I don;t really think it justified . Just my two cents

AMD's Ryzen CPU's and the infinity fabric speed makes it pretty useful, latency also matters more so hitting lower timings can still be useful even against the usual recommendations where the main thing is the clock speed and how that matters more than the timings and then there's the whole process with secondary timings and much more which I wouldn't be able to say much about, I can see the results though from a few of the comparisons or benchmarks available.

(This image is from Techspot.)





So from the reference DDR4 speeds of 2400 and CL15 primary timings at 126 FPS average which then when that's up to 3600 CL16 results in 135 FPS average that's nearly a 10% improvement in average framerate there for this game.

Push the infinity fabric speed higher (Even above the 1800 clocks.) with faster RAM and also retaining the lower timings and that's above a 20% increase for those top two results here.


Most of this besides the top performers here is gained just enabling the XMP and doing some light testing and comparisons checking stability and performance while ensuring voltage and such isn't under or overshooting if set to automatic instead of manual values but maximizing gains is pretty tricky although the results seem well worth it if it can be made stable.

Hey guys. I am new to this forum and don’ t now much about overclocking RAM. I’ d really appreciate help. Thanks.

I just bought new PC with RAM overclocking potencial in my mind. I did OC GPU and CPU in the past but never RAM.

My Setup:

Ryzen 9 3900x
Asus Rog Strix RTX 2080 ti o11g
Asus x570 -e gaming
G. Skill Trident Neo 3600 CL16 (16 16 16 36) 2x16gb (it is B-die)
Seasonic Prime 850W

Here is a thing, I used DRAM calculator for Ryzen (v.1.7.1) imported XMP from Thaiphoon (in nanseconds) to get a correct info on the left side.

I went into bios and filled out everything that was available in my bios exactly as said in calculator. Although I made a mistake I didn’ t buy Crosshair motherboard because my bios is lacking DRAM Power supply options (current capability, power phase control ect.).

At first I started out with DOCP enabled and it didn’ t work. Then I read somewhere to load optimized defaults. Afterwards I tested safe present and fast present with recomended values from calculator. I also tried it out with max voltages in case low voltages were the problem.

Here is what happened:

In safe and fast present with recomended values my PC went in a multiple reboot (turning on and off for 4 times), than it went into safe mode and I had to press F1 to go back to bios.

When I went with higher voltages (max values in calculator), I got blue screen error and had to clear CMOS.

I really can not find a solution after searching for 15 hour straight. All forums all videos - nothing. People are just saying it works for them..

One more thing I also flashed latest bios in case it was corrupted

Am I missing something?
Is DRAM calculator for Ryzen wrong?
Is it my x570 -e gaming motherboard (it is missing some values), I think Crosshair has everything.
Is something wrong with my RAM sticks or I just lost silicon lottery? I think if it was a silicon lottery higher voltages would solve the problem, especially with safe present.

Here are some photos of a program calculations values. I also marked red all the values missing in my bios that I just was’ t able to fill out.

Thank you.

That's rather weird, I got the same kit as you a month ago and mine is totally stable with the "fast" setting and with 3733Mhz instead of 3600Mhz and 1,35v (XMP standard voltage), my board is the Aorus Master though. What are your RAM temps?
