Hello, I assembled a computer for my client with the following parts: ASROCK B850M Pro RS WiFi mATX AM5 DDR5 Ryzen 5 8500G 2 X Kingston DRAM 8GB 5600MT/s DDR5 CL36 DIMM FURY Beast Black EXPO Kingston KC3000 512GB SSD Seasonic PSU ATX 3.1 750W Gold - FOCUS GX-750 V4 I installed Win 11 as well as all the drivers. So far everything is fine. To use the hardware capabilities, I launched EXPO from the quick menu. After a restart in the BIOS, the RAM speed remained at 4800MHz. I also checked in Windows. There it was also 4800MHz. I decided to manually adjust the RAM speed in to the settings: F6 ??Advanced Mode -> OC Tweaker. There all the options are grayed out/disabled. I did not see an option to enable DRAM Freyauentsi. I decided to update the BIOS to the latest version 4.10 from the Asrock website. The update went through successfully, but I still don't have the options to enabled ore change the RAM speed. Both RAM sticks are visible in the BIOS and Windows. They are in slot A2 and B2. |

You can try clearing CMOS and checking again if you haven't already done so. If that doesn't help then open a support ticket with ASRock: https://tw.asrock.com/events/tsd.asp" rel="nofollow - https://tw.asrock.com/events/tsd.asp It may be deliberate given the 8xxxG series have been known to have instability with EXPO enabled. You can ask ASRock in a support ticket for clarification. -------------

I clear the CMOS before and after a bios flash. No effect. I have submitted a request and am now waiting for a response from the Asrock support team. Thanks for the help. :) |
