Memory Training Issue With 2 Sticks of RAM in Dual Channel.

[Killerjoe11]

I've just recently built a new PC about a week ago (https://pcpartpicker.com/list/tdsdwY) and am having issue posting with 2 sticks of ram. I can post the system every time with one stick of ram in any of the motherboard slots (using either of my sticks). When using 1 stick, I was able to post with and without expo as well. When I add in the second one (one in A2, the other in B2), the computer usually fails to post and will either automatically restart the PC and try again or get stuck trying to train (this is also with and without expo). Eventually, I can get the system to post after multiple restarts with 2 sticks and it works fine (passes 4 rounds of memtest86), but will exhibit the same issue if memory training is needed again. I'm lost at whether this is a CPU or motherboard issue. To my understanding if it was a motherboard issue, one of the ram slots would not work and what I'm experiencing is a CPU issue? I'm not fully sure and don't have extra parts to test if one or the other is faulty. I believe the ram should be fine since both work in single channel. I bought the motherboard, ram, cpu, and case on a newegg combo deal that is no longer available, so I'd like to if possible RMA/replace the items that are faulty if need be instead of returning all the items. I'm not sure if I can RMA/replace something that may or may not be faulty through newegg?

does it work with two ram sticks if there isn't one in b2?

I've changed it to A2 B1 and it's experiencing the same issue with A2 B2.

if you take out your cpu are there any bent pins in the socket or markets on the cpu pads?

AMD based systems can have painfully slow RAM training. It is not unusual for a new system. Let it sit there for awhile. After the BIOS comes up. Enable Memory Context Restore.

The pins and pads looks good. I don't have a microscope or anything on the pins, but looking at it looks fine.

Does it take hours? The PC can sit there forever.

It can take while. Times differ depending on your hardware. Might need to update the BIOS.

or the chipset drivers

I've tried F34a, F33, F32, F30 (default one that came with the mobo). All do the same thing. I'm on F33 since F34a is a beta branch.

I've tried both AMDs latest chipset drivers and my motherboards latest, no difference.

If you can get into Windows. I would check Device Manager. See if there is anything highlighted. From there you can find hardware errors and it will list the error codes. You can web search the error codes for more info.

Doesn't look like anything is highlighted?

Device Manager looks fine. So far this sounds like a RAM issue. You might have better luck with RAM that has a CAS Latency of 30.

I guess I'm confused how this could be a ram issue if both work individually?

It still can be a RAM issue. Just that they cannot work together. A lot of computer issues make no sense.
