Memory DOA?

[KingCollins]

So I have a Gigabyte B450 AORUS ELITE, I had 2x8GB 3200mhz memory in it and it ran fine.

 

I purchased a Crucial 62GB kit (2x32GB) CP2K32G4DFRA32A, and it seems quite flaky....? Trying 1 DIMM at a time, 1 DIMM boots no problem in slot 1, and the other DIMM mostly fails but has booted once?

 

I've tried the usual troubleshooting:
- Booting 1 DIMM at a time

- Tried slots 1 & 2 

- Tried slots 3 & 4

- Checked bios version (F51 which is quite new)

- Cleared CMOS each time I made a change

- Loosened the CPU cooler to relieve pressure

 

Crucials site says the kit is not compatible, but I cannot see why not. Standard 1.2v UDIMM. The MB also supports 4x32GB kits.

Does this sound like a compatibility issue or a DOA memory module? I would have thought if 1 DIMM boots, the other should?

no it doesn't, unless it's the V2

this sounds like the DIMM is just flaky. Can you check the contacts in the ram mobo slot and the contacts on the actual DIMM?

This v1 vs v2 stuff is so annoying. I cannot figure out what version I have, but looking at the pictures it looks like I have the v2?

 

But checking my BIOS version, F51 is only listed on the V1, so now I'm wondering do I have an incompatible BIOS installed?

Also, from the V1 user manual:

of system memory
Dual channel memory architecture
Support for DDR4 2933/2667/2400/2133 MHz memory modules

Support for non-ECC Un-buffered DIMM 1Rx8/2Rx8/1Rx16 memory modules
Support for Extreme Memory Profile (XMP) memory modules
 (Go to GIGABYTE's website for the latest supported memory spe

I'm so confused....

Ok, I definitely have the V1.

Both supports 128gb according to gigabyte:

@KingCollins

Did you try clearing CMOS? Turn off PC, leave PSU on. Plug in memory in slot A2 and B2.

Yup, I cleared it every time I made a change. Unplugged the PSU and jumped the CMOS pins (didn't take out the battery though). When it does boot with that single stick, it says "CMOS reset" in the BIOS

You unplugged the PSU? Leave the PSU on while clearing CMOS. Short the two pins with jumper or screwdriver. On newer boards this is how to do it. Only need to turn off PSU if you remove the battery. Did you notice if it was actually cleared? Should prompt you when entering BIOS.

I was uner the impression the PSU nees to be unplugged? 
Yes I get a message in the BIOS

The PC has been running for 30 minutes with the single "good" stick with no issues.

 

I swapped it over to the other stick, fails to boot.

 

Swapped back to the good stick and it boots.

I think its a DOA DIMM module.

Damn you're right. They changed it at some point. I was puzzled when I first got my B550 elite. Couldn't clear bios without PSU plugged in and it's even in the manual. Your board, B450 is "the old way": https://download.gigabyte.com/FileList/Manual/mb_manual_b450-aorus-elite_e_1101_v1.pdf?v=c929cd26479904dd13427b268b6f94c6

Well that interesting, I'll make sure I'll keep an eye out for the future! I want to be 100% sure before I process a refund so I followed the manual very closely

That's a good thing! I'm pretty sure your RAM is bad, if it can't boot every time with one stick.

[KingCollins]

Ok cool, I'll go ahead and process a refund. Thanks everyone
