Another code 15 problem on Gigabyte

[noreplyse]

Hello to everyone on this great community. I have a slight problem with my current build. It basically won’t do dual channel. 

 

I’ve had a GA-Z97-HD3 for some years, paired with an Intel i7-4770 and 2x8 DDR3 RijawsX running @ 1600MHz on dual channel (part no. f3-12800cl10d-16gbxl)

 

It functioned perfectly up until some day about a year ago when it started crashing a lot and was giving a lot of BSODs and it would only post with the memories set @ 1333 MHz. After some weeks, it wouldn’t even post with two rams (in any combination). That issue turned out to be socket related (bent pins), and the mobo was repaired under warranty. I was able to do dual channel but the mobo would only post with the memories’ frequency set to 1333MHz. 

 

This week it started doing the same thing, a lot of crashing and then it wouldn’t post with any of the two rams, but it would post with only one ram stick on the two furthest sockets.

 

As I thought it was a mobo related problem, I bought a Z87x-UD3H that was conveniently on sale, but the issue remains. It gets stuck at debug code 15, regardless of where the sticks are plugged in, and it only boots with one of them on the two furthest sockets. (Note: it is worth mentioning that the memory sticks now run at 1600MHz). 

 

At this point I don’t know what may be causing the problem, and I don’t have a spare Haswell processor or two DDR3 ram sticks to test. 

 

I’ve also tried increasing the MCU and ram voltage a little bit, but no dice. 

 

If you have any suggestions I would appreciate it. 

 

Thanks.

I'm going to say it's probably the memory. Try loading optimized defaults on the motherboard, but if that doesn't fix it it's probably just bad or worn out memory

Yeah, I thought that as well, but then the sticks would need to run on every slot, or am I wrong? Because they only work (one at a time) in the channel B slots on both motherboards (labeled as DDR3_1 and DDR3_3).

If I put only one stick on any of the channel A slots, the system gets stuck on code 15 and it doesn’t boot.
