Corsair Vengeance DDR4 issues with MSI Z107A Gaming M7

Hi Guys

I purchased the above M7 with a GTX 980 ti, i7 6700k and 16GB kit of corsair vengeance ddr4 3200 ram.

At first I couldn't get it to POST, but once I removed 2 sticks of ram it seemed to work.

Now I can only make it boot if I only populate rows 3 and 4.

When I use rows 1 and 2 or put all 4 sticks in it fails to post with the following code loop on the motherboard output panel:

00
4c
55
0d
19

I have verified the cpu cooler is seated properly and not too tight. Also there are no bent pins.

I also tried lowering the ram timings, but this had no effect.

Can anyone suggest any other things I can try?

Thanks!
 
Have you updated the bios on the board to the latest revision? I see 1.4 is out there from 8/5... but not sure what it shipped with.
 
Have u tried to see if it will boot with only 1 stick?

If yes, than test the others and see if there is a stick it cannot post with, and if it posts with all 4 in a single slot maybe than it could be bad board or board doesn't support the kit u have purchased.
 
Have you confirmed all four sticks work by using the known good slots?

Please send a ticket into MSI support. BIOS may need to be updated to support that X99 XMP profile correctly. My G.Skill 3200 MHz kit works flawlessly, but I do know that because that kit was designed for X99 and not Z170, there may be some problems (especially since that kit is only listed as good for two X99 boards, the Asus X99 Deluxe and Rampage V Extreme).

My kit has 16-16-16-36 timings, likely your kit has different ICs than mine (like I have Hynix, you have Samsung)

I've opened a ticket with MSI, will see what they have to offer.

It's been a while since I got in this early with a new cpu model, I'd forgotten the pain of the early adopter!

The problem I have is since it's a new DDR format I cant test the sticks in another board :-S
 
Joined up so i could chime in. I'm having this exact same issue with Crucial Ballsitix RAM, so it seems like it's a BIOS issue and not a RAM issue.
 
I new bios came out on the 12th... did you try that (phaser or the OP)?
 
hey i'm also having the same issue- although i cannot put the RAM into 2 slots at once- i can only use 1 slot either 3 or 4 :( again i'm the same in terms of bios etc- please let me know if you fixed it- and how!
 
I've still been trying to crack this but I think I'm down to just replacing the motherboard. I have tried 3 different types of DDR4 including G.Skill Ripjaw 4 with a model number that matches the RAM Compatibility List for the M5.
I've also tried various BIOS settings and I can't get anything to post with RAM in slots 1 or 2.
I'm going to go to the local Fry's and grab another MSI board to find out if it's a specific issue with our motherboards or something broader. I'll update afterwards.

Yeah, I'd like ot hear how this pans out, since I haven't had any issues at all, but then again, I don't have Corsair ram. It is possible it's a CPU issue, but it could be a bad board, too.
 
Ok, this is definitely a problem with the motherboard.
I replaced my M5 with an M7 and it is able to boot and recognize all 4 sticks of G.Skill Ripjaw 4 2666.
Again, this is the Z170 Chipset running an i5 6600k

I wish there was an easier answer for everyone but this was the case for me. Seeing as how several folks are having this problem it looks like it might be a hit-or-miss issue with these MSI boards.
 
My luck is that 3 G.Skill Ripjaws 4 kits couldn't work at XMP profiles on Z170 board and all were Samsung based, designed for X99 - 2666, 3000, 3200. 3200 c16 couldn't run stable at manual settings too. 2 Hynix kits were working fine ( both 3000 ). Ripjaws V 2x8GB 3200 C16 are working fine on Z170 but are not working at XMP on X99 ( actually this is not important for me ).
Crucial 2666 and Kingston 2666 designed for X99 were both working fine on Z170 and X99 boards. I have no Corsair kit right now to test.

Regardless what memory are you using, it still should boot at standard SPD / Auto settings. If it doesn't work with more than 1 memory kit then it's probably motherboard's fault or problem with BIOS.

Other thing is that I simply don't trust MSI motherboards after couple of weird problems with previous generations and barely any help from their support. Literally every MSI board I had went to RMA in ~1 month after purchase.

I was going to suggest ensuring the cooler is mounted correctly and that there aren't any traces running under one of the mounting bolts.
Some Manufacturers have made ridiculous design calls by placing them to close to the mounting holes and they can become damaged. Using an insulator can localize the pressure immediately to the region it is meant to be.

Yeah, XMP works fine on my M7. None of the 3 types I tried would work on the M5, I didn't try anything but the G.Skill in the M7 but I assume the others would have worked as well.

Tried this, along with just about everything else. This RAM issue seems to not be uncommon. A quick search of the MSI boards shows several more people with the exact same issue.

This fixed the problem for me. I had already tried loosening the CPU fan, but I never checked the bolts that's placed on the MB. you just saved my week Caring1, Thank You!!!
 
So MSI got back to me and told me that I needed to unplug and clear the CMOS, which is actually the only thing I haven't tried... I'm at work now though so can't try it. (They also suggested a whole bunch of other things that have already been suggested here)
 
Hey, so I fixed it- I bought a really good magnifying glass and one of my pins was like 1mm out- I bent it back and it works like a charm now!!! Also I used insulated washers on my water cooler mounting.

Is it just me or is there very little quality in PC parts anymore?
