Hi there,
I'm building a new PC with the following configuration:
- Motherboard LGA 2066 Asus Prime X299-A (all drivers installed)
- CPU Intel i7 7740X,
- DDR4 2x16GB 3200 mHz memory sticks Corsair Dominator Platinum
- Watercooler CoolerMaster Master Liquid Pro 240
- PSU Corsair TX850M
- Windows 10 64 bits (installed on a SSD)
When I started the PC and ran AI Suite 3, I noticed that the "DRAM Voltage AB" is low (0.304V, while I suppose it should be 1.2V). DRAM CD voltage is ok (1.2V). See attached picture:

(by the way, what is DRAM AB voltage? Is it the voltage supplied to the memory slots? If so, which ones? I could not find any explanation on the manual nor on the web)
When I check CPU-Z, the memory sticks apparently are running at the right frequency, and the PC is apparently stable (I'm writing this message from it). If I try to do a stress test with MemTest, it does not run ("Could not allocate 4095 MB").
I have already replaced the PSU for a test, and switched memory sticks position, but the problem remains.
Does anybody have any idea of what is happening and how can I solve it?
I've already contacted the supplier requesting the replacement of the mobo, but I would like to try something, as this is going to be a real pain for me (need to disassemble, ship back, wait for new one, assemble again, spending more thermal paste, time, etc). I would be very grateful for any helfpul thoughts.
Best regards,
Antonio Intini
