X670 RAM problem

[squelch41]

I'm using a X670-P wifi board, a ryzen 7700x with 2x16Gb Corsair Vengeance 5600MT DDR5

 

I can only post with one stick of ram. in A2 slot. If I put the other stick in any other slot OR move the stick into a slot other than A2, I get bios beeps of long-short-short which seems to indicate a ram error.

 

Both ddr5 sticks work on their own but not together.

 

Running the bios released today.

Tried with default settings and setting ram manually to 4800 and 5600 but same result.

 

When I very first installed the ram, it did work in A2 and B2 as a 32gb pair but then it just stopped POSTing.

My thought is faulty RAM but other option could be the motherboard.

 

Anyone else had similar?

 

Should I be able to POST with 1 ram stick in any of the other slots? (I note the manual says a2 is the 'recommended' slot for 1 ram. stick but doesn't say it ia mandatory)

 

thanks!

What is your SOC voltage?

B2 should work as well. A1 and B1 can technically work, but their support is very sketchy on most AM5 DDR5 boards when populated on their own. 

 

I've seen somewhat similar behavior on other boards, the issue ended up being a bad CPU mount. Try reseating it to see if that helps. Otherwise I'd be assuming it's probably a bad motherboard.

Thanks for that advice - I look the CPU out and closely examined the socket - there was a REALLY subtle difference in the way the socket looked at one corner so I examined under a microscope and 2 pins look like they arent formed properly with the underlying plastic looking malformed

 

Having re-reseated the CPU x2 it is now working with both RAM modules but I am going to RMA the board

 

Thanks again
