Gigabyte Gaming 7 - memory initialization error

post #1 of 3
Thread Starter 
So I've got my new build completed with a Gigabyte Gaming 7 motherboard and Skylake 6700k. I have 16GB (2x8GB) of Corsair Vengeance LPX DDR4 2400MHz memory installed. When I first booted up the first thing I got was an error 55 code on the motherboard - memory initialization error. It seems I'm not alone with this issue with this motherboard.

I had the sticks installed in the 2 alternating RAM slots (both red), and that's the error I got. After some trial and error (swapping sticks, etc.), here's what I've got:

- No sticks installed - error 55 code - memory initialization error (several long beeps).
- 1 stick in each red slot - error 55 code - memory initialization error (several long beeps).
- 1 stick in each black slot - error 55 code - memory initialization error (several long beeps).
- 1 stick in the first red slot - boots okay - I can get to BIOS.
- 1 stick in the first black slot - boots okay - I can get to BIOS.
- 1 stick in the first red and 1 stick in the first black - boots okay - I can get to BIOS (BIOS sees 16GB RAM)
- 1 stick in 2nd red slot and 1 stick in 2nd black slot - error 55 code - memory initialization error (several long beeps).

It looks like if any memory is installed in either the 2nd red or 2nd black slot, I get the error. If I use just the first 2 slots, it boots.

So what's going on here? Why can't I run with the sticks in matching color slots like I thought I was supposed to be able to do? My memory isn't listed on Gigabyte's list but many of the other Corsair Vengeance LPX sticks are. Am I having a CPU problem or motherboard problem, or bad slots (unlikely after my testing), or a firmware/BIOS issue?

Can anybody help? I'm not an expert by any means and this is just my 2nd build. I read other threads that suggest this board has problems with memory over 2133MHz but then why does my board boot if I have 1 stick in red and the other in black?

I thought it was maybe that my memory was incompatible (2400MHz) but if that was the case why does it work on the first 2 slots? In the BIOS it says the speed of the memory is running at 2133 when plugged into the first 2 slots.

I really need some advice here. The system boots up every time fine if use the first 2 slots (labeled DDR4_1 and DDR4_3) but not if I use either the 3rd or 4th slots (labeled DDR4_2 and DDR4_4). I tried setting XMP to profile 1 see if that made any difference. It booted up fine and is running at 2400 as long as I use the first 2 slots. When I switched a stick to the 2nd red slot, I got the same error again. It's like the last 2 slots are dead. The manual says when enabling dual channel mode it's recommended to install in the same color slots. But this seems impossible for me with this board.

Am I overlooking something or reading something wrong? I also rest the BIOS to optimal settings and that made no difference. I also tried setting the dual BIOS switch on the board from dual BIOS (default) to single BIOS. Again that made no difference. I'm out of ideas. I don't know at this point if it could be the board or the CPU, or goofy BIOS. I called Gigabyte and never got an answer - I'm waiting for an automatic call back but they haven't called yet. Any ideas? It would be a major pain to have to disassemble this and start shipping parts back, especially if it's something simple I'm overlooking. Shouldn't the memory work in both red slots?

I got a call back from Gigabyte and after explaining my issue and troubleshooting, she says it sounds very much like I have some bent pins. She said if the system boots up with the sticks in the first or 2nd slot then it isn't a memory compatibility issue. So I guess I have to start pulling things apart and see if I indeed have some bent pins.
