[SOLVED] Faulty RAM or MB??

[Avi Assayag]

hey m8's!

I've bought this MB (Gigabyte Aorus Ultra x570), and used 4 sticks of 16gb each to a total amount of 64gb or ram (G.Skill 4x16 @3200 DDR4).

only the 2 slots close to the cpu are being recognized (DDR_A1, DDR_A2). the 2 outer slots are not showing up in the bios or windows (DDR_B1, DDR_B2). Also, I'm getting this error message:

"pmu memory training error at socket 0 channel 1 dimm 0 & dimm 1"

I'm not using xmp, as it is not enabling me to boot, nor am I running it at the intended speed of 3200mhz. it runs on 2133mhz only, and at half capacity.

I'd love to get a tip on how to enable them or get any other help.

thank you.

The fastest 64 GB (4x16 GB) RAM kit I see that G.Skill lists as compatible is FlareX 2933 (F4-2933C16Q-64GFX).
The next fastest is 2666 Trident Z Neo kt and the other 2 are 2400 kits.
So f it isn't one of the kits listed here, it might only run at 2133.

Your MB QVL shows these 64 GB kits as compatible at 3200:
F4-3200C16Q-64GTZR
F4-3200C14Q-64GTZR
F4-3200C16Q-64GTZ
F4-3200C14Q-64GTZSW

What Exact kit model number do you have ?

F4-3200C16Q-64GVK is my model.

Have you tried running them at 2400 or or 2666 or 2800 or 2933 ?
If not I would try setting the XMP Profile for 3200 and then change the DRAM Frequency to 2400 and see if it boots.
If it does try again at 2666 and then 2800 and finally at 2933.

So it turns out that the culprit was a bad contact of one of the pins. I disassembled the cpu and reassembled it again, and puff! RAM is being recognized again.
