BIOS RAM configuration options are unavailable.
BIOS RAM configuration options are unavailable.
Hi, I checked but didn’t see any answers about this issue, so I’m hoping it’s not a very basic question. I recently assembled my own AMD 7800X3D system and everything worked perfectly, so I offered to help my sister when she asked for a build. Considering her needs and budget, I selected an AMD 8700G (I suggested she could get more power if needed). For the motherboard, I chose the ASRock B650M-H/M.2. I found a good deal on Patriot Viper Vengeance 2x16GB DDR5 RAM with 6000MT CL30 and 4800CL40 RAM. The 8700G supports up to 5200MT, so I thought it would fit, even if it didn’t reach its full capacity. Both XMP and EXPO profiles let me set speeds at 5600 or 6000. The 6000 profiles didn’t boot at all—hoping it would take forever to initialize. After about 20 minutes with no activity on the LEDs, I switched to the 5600 profiles, and the system started working properly. However, it was still running at 4800MT. Reading some confusing discussions made me doubt if the problem was a display issue. Benchmarks indicated slow performance. Oddly enough, the BIOS showed two columns for speed and voltage—current vs. set values—but it was actually set to 5600 while running at 4800. Changing it to 5200 didn’t help either. When I explored AMD Ryzen Master, I discovered the “Expo” option. I enabled it, rebooted, and got a stable system at 6000MT. Yet, even after adjusting in BIOS, when I pressed any key in the BIOS settings, the actual speeds reset back to 4800. I can set the RAM speed to 6000MT-EXPO in the BIOS, but not from there. What’s missing? Cheers, TOM
I'd start with a BIOS update first, but since I've used this board before, I found enabling EXPO confusing. It seems to be set up in an unusual way, so I usually skip it and enter the EXPO settings manually. If that doesn't work, try adjusting all EXPO parameters—like memory timings, frequency, and voltage—directly instead of letting the BIOS manage them.
Bios problems, restoring the bios could change the standard 4800 setting again
No new BIOS update is available. Would you like me to re-flash the same BIOS? Your adjustments to the "set value" are recorded but don't take effect, causing the current value to stay unchanged. It seems xmp/expo is attempting to apply invalid settings, so the BIOS rejects them and reverts to defaults. I’m curious if there’s a hidden "overclocking enabled" toggle that remains disabled.
