Hi everyone, I’m facing a problem with my EXPO 1 profile. When I run MemTest86, it reports errors exceeding 300. The RAM is listed on the motherboard’s QVL. EXPO 1 should read 6000 MT/s 30-36-36-76 at 1.35 V, but MemTest86 shows 6000 MT/s 30-36-36-76 at 1.10 V. Interestingly, in my UEFI it displays 1.35 V applied, and both MemTest86 and UEFI images confirm this. Is the voltage actually being set incorrectly? Should I adjust EXPO 1 manually, or is there something I’m misunderstanding about how MemTest86 reports voltage? For reference, I achieved a pass with these settings:
EXPO 2: 5600 MT/s 40-40-40-84 at 1.20 V
Base JEDEC: 4800 MT/s 40-40-40-77 at 1.10 V
A custom setting I tried: 32-40-40-86 at 1.35 V
Any suggestions would be really helpful — I’m just starting out with PC building and this has been challenging.

Welcome to the forums, newcomer!
The RAM is on my motherboard’s QVL list.
Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
If your motherboard has 4 ram slots but you're working with 2 sticks of ram, what slots are they populating on said motherboard? A2 and B2?
