SODIMM 1 slot not working

Brand new NUC11PAHi5. 2 DIMMs. Either one works in the (upper) SODIMM 2 slot. Neither works in the (lower) SODIMM 1 slot...get a 3-blink error. Same if I populate both slots. Cursory check of the slot reveals no bent pins or obvious shorts. Any ideas or is this just an RMA situation?

Just to close the conversation since Intel never chimed in, presumably this Intel board is as finicky about RAM as were first gen Ryzen boards. The behavior I experienced seems to be indicative of unsupported RAM. This same RAM (PNY XLR8 16GB PC4-26400 3200MHz 1.2V CL20) might work fine for you as it is known to work in some NUC11PAHi5/7 units. But apparently some combination of BIOS settings and, uhh, something seems to make it not work in all units. So, avoid this RAM despite it seeming to check all of the required boxes for compatibility.

And, the exact model numbers of your sodimms are?

Same here with the same RAM

That's creepy. Almost like you recorded me doing the same exact thing with the same exact things. Yes, it's the same RAM in the same slot(s) with the same issue(s) on mine. There must be some kind of incompatibility with this RAM. Perhaps someone at Intel can chime in. Seems to be perfectly fine in terms of specs. Certainly don't want to eat a restocking fee on this...

 

You say it worked for you on a prior BIOS? Was it an earlier one than 0041? Or maybe 0042 was an anomaly that actually worked?

It worked just fine with 0041 BIOS with Zero problems

when I updated the BIOS to 0043, I got the 3 blinking issue

Mine came with 0041. Literally just unboxed it and turned it on this afternoon. So no BIOS changes. Though I suppose I could try to update it if that were a potential solution.

Stick with BIOS 41 or 42 until Intel puts out an updated BIOS. PA BIOS 43 also kills GFX output via TBT, so all round bad update.
