Hello people.

One step before RMA-ing my Z97X SOC Force, I thought to post a question here because perhaps what I face can be resolved without having to RMA this board.

The facts:

- Clean Windows 7 64 bit installation (performed on Optimized Defaults), BIOS F6.

After finishing with the installation, I tried to load my RAM's XMP profile(s). It does not start. It loops infinitely, stuck on POST and I have to shut it down, load Optimized Defaults = RAM at 1333MHz, to POST, and boot in Windows.

I've tried:

1st and then 2nd stick on DDR3_1 slot, XMP works
1st and then 2nd stick on DDR3_3 slot, XMP works
1st and then 2nd stick on DDR3_2 slot, XMP doesn't work - stuck on POST.

I've also tried with both sticks, 16GB. on slots 1 and 3, XMP works.

DDR3_2 slot works when RAM is running at 1333

When both orange or black slots are populated and I'm trying to run any XMP profile, or even set my RAM manually at 1866, 8-9-9-24, 2T , 1.6V, it cannot even enter into the BIOS. It loops infinitely on POST and the last error code I was able to see was 4F. Then it quickly shows b6, I think, it shuts down and it starts all over again...

What do you think is the problem? Is it something that has to do with software or should I RMA this motherboard?

My RAM has worked in the past, like 20 days ago, without any problem on this SOC Force motherboard. Also, until yesterday I had it installed on my other mobo, the Maximus Hero VII, running its XMP profiles without any issue.

I honestly do not know what happened, all of the sudden, with this DDR3_2 slot, of this mobo!

Thank you.

Guys, anyone?

I've disconnected everything and plugged one of my monitors in the iGPU. Still the same.

Why aren't my XMP profiles working, all of the sudden, neither on the 2 orange slots nor on the two black ones? In addition, when I place a single stick (8 GB) on each slot, besides the DDR3_2 slot, the XMP works. DDR3_2 orange slot does not work at 1866.

Everything works normally with all 16GB (2 sticks) when I run it at 1333.

Is this a problem of the motherboard or something else?

I repeat that this same RAM was functioning perfectly until yesterday on my Hero VII board, and also like 2 weeks ago, on this SOC Force board.

First thing I would do is to update the BIOS on the SOC Force to the latest version.

Try running MemTest86+ on the RAM DIMMs to see if they are working. Do it both on the Hero and the SOC Force.

Also test which slot is broken. Try 1 and 3, then 2 and 4 on the boards with both DIMMs to see if XMP works. It is probably slot 3 though as you note.

Finally, try overclocking the RAM manually and setting the timings yourself.

If all of the above fail, then most likely you have a bad DIMM slot and you will have to RMA the Gigabyte board. If the RAM doesn't work on both motherboards, then it's probably a bad DIMM, so you'll have to RMA that instead.

Hello, and thank you for your reply.

My SOC Force is faulty. I have tried a few things, not everything you have suggested... I think there is no need to try all of these things. This motherboard has worked in the past with this specific RAM kit -certified for the SOC Force by G.Skill, by the way- and there is no reason for it to not work on its XMP profiles any more, except if the motherboard has become faulty, all of the sudden...

I have not tried everything but I have tried a few things:

- BIOS F6, the latest official, was already flashed but I have flashed it again. The memory sticks were (are) installed in slots 1 and 2, the orange ones. The XMP profiles do not work. It cannot boot, it does not enter the BIOS, it just loops endlessly shutting itself down, in the way I already described. Then I press the power button, shut it down, then I press clear CMOS or even CBAT, and it starts normally. But my RAM runs at 1333MHz, of course.

The only thing I can think of, is that one or more ram slots were about to die, and now they have died. The problem was there on the motherboard, hidden, and now it appeared.

I opened this topic because perhaps someone had a similar experience with a Gigabyte or another motherboard. It is weird that it works at 1333 but it cannot even boot into BIOS when ram is set at 1866, manually or via XMP.

I will now install the system back on the Hero VII - thank God I already have an SSD with Windows + drivers installed for that board- and then I will memtest my RAM on the Hero. I don't think I will find any problem with my RAM, though.

Thanks.

I've installed Windows, Office 2013 and the rest of my software on my Hero VII using my RAM's XMP profile_1, during the entire installation process. Everything went great. I had absolutely no problem. This proves that my RAM has no problem but I will most probably memtest it, one of these days. I will RMA the SOC Force.

Thank you.

Regarding this topic I'd like to ask one more question:

- Is it possible that the problem I have described is happening due to motherboard's bent pins? Can bent pins cause something like this? Specifically, the DRAM to function flawlessly at 1333 MHz but to not even boot into the BIOS, to intermittently restart, when set at 1866?

Thank you.

I'm not really sure about bent pins and RAM only working partially.
But from how you described testing the memory earlier and Slot 2 not working it sounds like that memory slot is damaged.

I could be wrong but I don't think a single CPU pin would make specific memory slot no longer function. I'd imagine it would have a bigger effect on the CPU using all of the available memory. Which again leads me to believe that the slot is the issue.

Perfectly fine to only use 3 of the Memory slots, although not the most ideal.

Looks like I'm not the only one with issues w/ their SOC Force, mine crapped out yesterday after a re-boot after updating linux. Would just power cycle and not even post to BiOS under either BiOS, can't be bent pins as my setup has been up and running since July. I've already sent in a request for RMA to Gigabyte as well just waiting to hear back from them on where I need to send my Mobo, really sucks was a great board up until yesterday.

I had the same issue with my UD5H, but that was due to 2 bent cpu socket pins. Current I still can't reliably boot into windows after bending them back.

I feel as if I should have read this thread before purchasing gigabyte.
