Asus Rog Strix x670e-e Amd Ryzen 7 7800x3d expo not working

Level 7

Hi everyone, i have this issue.

I recently build my new pc and after the build i immediately update the bios with the latest update (via usb) available, the 1709 to be precise, after the update I try multiple times to enable expo for unlock my ram to go to 6000mhz, but every time at the restart i go to the "safe mode". Now i try for some weeks to enbale expo via Ryzen Master and it works but is not stable ( for exemple when i play some game i have a lot of stuttering, but when the fps goes up to 120, at 60 is there but not frequently as over 120 fps).

My specs:

CPU: Amd Ryzen 7 7800x3d

Ram: Corsair Cominator Platinum Rgb DDR5 (CMT32GX5M2D6000Z36)

Motherboard: Asus Rog Strix X670E-E Gaming Wifi

Gpu: Asus Rog Strix RTX 4090 OC

Ssd: 2x WD_Black SN850 X 1TB

Hdd: Seagate ST4000D 4TB

If your mobo works in normal mode and not in EXPO mode then the RAM timings may be the problem. I noticed that your RAM is not listed in the mobo QVL, so try other memory sticks if possible. Also, run a memory test like memtest86 before switching to EXPO settings to make sure your RAM is OK. 

Hi cabwav, 

I do the test and change the ram timings but still no improvement and no expo mode.

After that i search the ram that is on the QVL of my motherboard, then i bought it and today i install and now evreything is working and the pc is now stable and smooth and i can enable the Expo mode.

So thanks very much.

Great! Don't forget to download and install the chipset and other drivers from the manufacturers website for your motherboard, run the Memtest86 to make sure your RAM is OK.
