Question Unable to set EXPO I profile with 7800X3D on Gigabyte B650 Aorus Elite AX V2

[lofej]

I'm using DDR5 Kingston 32GB 6000MHZ CL30 dual channel (KF560C30BBEAK2-32)
I can enable EXPO II, which is 5600mhz, the PC seems to work just fine, but thats not why i bought 6000mhz to not use its full potential.
What am i missing here? I have the latest BIOS firmware, enabling EXPO I will not get me over boot, i have to get back to BIOS and i either disable or set to expo II.

Could anyone recommend me what else I should check? I this an issue of the RAM's or the other component?

Thank you.

I have the latest BIOS firmware
For the sake of relevance, can you mention the BIOS version you're on for your motherboard? If you flashed the BIOS recently, did you clear the CMOS after verifying your BIOS was flashed to the latest successfully?

How are you cooling the processor? might want to try and relieve some mounting pressure on the CPU's IHS to merely have it rest on said IHS(in order to do this, you should lay the case on it's side). Perhaps excessive mounting pressure is causing an uneven seating on the socket. Would also be a good idea to inspect for bent or broken pins.

I'm using the F33a which was released FEB. 07.
I did not clear the CMOS, it shows up correctly in the bios. Not my first bios flash.

Using a Elite Capellix H150i, I dont think that can be an issue here, the PC works fine, temps fine, no bent pins or anything broken. Also not my first build.

You can try increasing the dram voltage, or manually entering the memory settings rather than relying on EXPO.

You might just be unlucky with the CPU or memory.

Seems to be okay now, what I did was to enable the following settings:
Low Latency Support - Enabled
XMP/EXPO High Bandwith Support - Enabled
UCLK DIV1 MODE - set to AUTO

Havent done a proper memory testing, run cinebench r24, few minutes of CS2, no crash or anything so far. Will report back if anything changes.

Interesting. Have to keep that in mind for my next crack at an AMD system.
