Well this exact ram reaches 3200Mhz with this exact same CPU on other boards, even ITX from other manufacturers. In this board it cannot reach 3200 even with tCL 20 and other timings extra loose.

I think this board is broken with dual rank ram, don't know if electrically or BIOS related.

If somebody from AsRock is reading this please can you check and confirm?]]> Tue, 05 Nov 2019 11:54:26 +0000 https://forum.asrock.com/forum_posts.asp?TID=12766&PID=69659&title=help-fatal1ty-b450-gamingitx-ac-memory-problem#69659 https://forum.asrock.com/forum_posts.asp?TID=12766&PID=69481&title=help-fatal1ty-b450-gamingitx-ac-memory-problem#69481 Author: Ray62

3000Mhz with a CL14 timing is a good setting for this RAM.
Remember, this is dual ranked RAM with a higher electrical load compared to single ranked and you have a 2600 CPU which is designed for max. 2933 MHz RAM clock.
If you will be able to reach 3200Mhz with increased timings, the result probably ends in a lower performance compared to this CL14 timing at 3000MHz.

BTW:
There is a dependency for tCL (CAS) to GearDown mode.
If GearDown mode is enabled, only even tCL values are valid, so it will be rounded up to the next even value.]]> Wed, 30 Oct 2019 06:36:42 +0000 https://forum.asrock.com/forum_posts.asp?TID=12766&PID=69481&title=help-fatal1ty-b450-gamingitx-ac-memory-problem#69481 https://forum.asrock.com/forum_posts.asp?TID=12766&PID=69471&title=help-fatal1ty-b450-gamingitx-ac-memory-problem#69471 Author: marsovac

I tried with 1.4V and 1.45V to no avail.
The only thing that changes is that i can lower timings even more.

I used Ryzen DRAM calculator to get to these timings.

But they work only on 3000Mhz and 3200 does not boot on any timings.]]> Wed, 30 Oct 2019 01:44:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=12766&PID=69471&title=help-fatal1ty-b450-gamingitx-ac-memory-problem#69471 https://forum.asrock.com/forum_posts.asp?TID=12766&PID=69461&title=help-fatal1ty-b450-gamingitx-ac-memory-problem#69461 Author: Ray62

The XMP timings are probably optimized for Intel.

I have a memory problem with Ryzen 2600.

It cannot even run stock XMP that has default to CAS15, if i fiddle with timing I can get it to work but at 3000Mhz max and not a bit more, but at that 3000MHz it works at CAS14 instead of the declared 15 and all timings tightened.

Seems there is a memory problem with the board that it won't run past 3000 Mhz.
Curently I would call it: Faul1ty B450 Gaming-ITX/ac :)

Modules are 2 double sided 16GB Corsair Vengeance LPX sticks for 32GB in total with Hynix AFR chips.

They are not in the memory QVL for Pinnacle ridge but I see there is one DS module that supports 3200, so it should also be able to work like that: ADATA AX4U3200316G16-SGZ

These Corsair modules worked with XMP timings and 3200Mhz exceptionally well in the Intel z270 i7 7700K system.

Can somebody help me to get to 3200?
Or can support improve memory compatibility in a future BIOS?


Typhoon says:

DRAM Manufacturer: Hynix
DRAM Components: H5AN8G8NAFR-TFC

Here are my CAS14 stable settings with all timings tighter than stock XMP:
