GA-Z87X-OC with Memory Issues and booting

Guys,

I'm having a few issues with my new build after retiring my old Q6600 Quad Core setup.

Here are the specs;

  • Cosair Carbide Air 540 Case
  • Gigabyte GA-Z87X-OC (BIOS version F6)
  • Intel Core i7 4700K Haswell CPU
  • Cosair 2x4GB Vengeance Pro (2133)
  • Cosair H100i Cooler
  • 128GB Samsung 840 PRO SSD
  • Antec Quattro 1000W PSU
  • Asus Nvidia 7800GTX GPU

On initial build, I could not get the build to boot at all, all fans would fire up, it would just show a blank screen, post code 19 on the LED display, then change to 15, still no display, then just shut down and start all over again, in a constant loop.

What I noticed is that on cold start all fans would fire, but on re-start and there after, the fan CPU_OPT would no longer fire up.

I had the two memory sticks inserted into slots DDR3_1 and DDR3_2 (orange slots) as recommended by the manual. When I removed the memory stick from DDR3_2 it now booted (although placing the memory stick into DDR3_3 also allowed it to boot).

All good so far, so I continue to install Windows 7 Ultimate edition, install drivers, Windows updates. The PC reboots, shows Gigabyte Ultra Durable splash screen, shows the Windows logo and just stays there, eventually after 2-3 minutes the PC reboots and the cycle starts again.

So I'm thinking that maybe the drivers or updates have somehow corrupted the OS, so I try to boot to Safe Mode and was successful, Restore to an earlier point and now have Windows back again.

So I carry on having to re-install drivers and Windows updates, this time I am successful, all good.

The next morning I boot up the PC, and the dreaded sticking at Windows logo problem has returned. I try Safe Mode again, the text of loading components is displayed and it just sticks there again for a few minutes, and just reboots again. I can no longer access Safe Mode either.

So, I think I have to install Windows again, so pop in the Windows 7 disc into the DVD Drive again, forget to press a key to initiate DVD ROM boot and Windows loads up just fine, go figure. This time I create a Restore Disc, and carry on. Install a few applications which force a reboot, all good.

The next morning again I try to boot the PC and the same thing, sticking at the Windows Logo screen. I try to get the damn thing to boot, no Safe Mode either. Then, all of a sudden it decides it will boot Windows after all after a hour of frustration.

I've noticed that sometimes it will stick at the Gigabyte splash screen for only a second or two, other times (usually when it will not boot Windows) it will stick for a good 15 - 20 seconds before deciding to boot.

At this point, I've no idea what the problem is, especially the RAM issue, I am thinking maybe I need to RMA this board after only owning for 3 days.

Sorry for the lengthy post, but I figured the detail is important and it may help someone else who hits this problem

I should add the CPU temps have averaged around 25C.

I have cleared the CMOS by removing the battery but it has made no difference to operation.

Another thing to add, I built the exact same spec for a friend using the same parts two weeks ago (except for PSU and GPU), not a single problem.
 
Are you using an ssd at all? And a sandforce controlled ssd? Is it stable in the BIOS if so I would flash to latest BIOS first,then take it from there

Hi - yes I'm using a 128GB Samsung 840 PRO SSD, not sure if it is sandforce controlled? It seems to be stable in the BIOS as far as I can see.

The current BIOS in the motherboard is F6, I believe this is the latest on the official website.
 
It will be fine with that ssd

Could try enabling xmp memory profile in the BIOS for your memory,also install the ram in staggered slots so from CPU socket to front of case miss a slot/install/miss a slot/install
 
wazza - I forgot to mention that I also have a 1TB Samsung HDD connected to the motherboard with all my backups from my old system.

When you mentioned a possible problem with the SSD it reminded me that when I can get Windows to boot, my 1TB HDD would not show in My Computer and Intel Rapid Storage Technology utility in my system tray would report a problem with the HDD, saying it could not utilise SMART function for it. It would allow me to 'supress' the SMART function for the drive, and then it would appear in My Computer ready for use.

So I removed the HDD, and bingo, motherboard boots rapidly every time.

I think the settings for 'supress' SMART are lost each time I do a Windows Update which is constant right now, this would explain why sometimes it would boot.

I will now try to resolve the memory issue, and as you suggested try the XMP profile.
 
Okay - I managed to select Profile 1 from within the XMP settings and noticed the following changes;

Memory Freq of 1333 now 2133
DDR Volt of 1.50v now 1.65v

I then tried the DDR3_1 and DDR3_2 (orange slots) designations again, but still not booting.
 
Right - I removed the 7800GTX GPU and attached my monitor via the motherboards inbuilt GPU HDMI port.

I then tried to insert the memory sticks into the correct dual channels (orange slots) and again no boot, it fires up, LED code goes to 15, stays there for a few seconds and then tries to boot again in a constant loop.

Problem is definitely pointing to the motherboard, it just concerns me that I will not be able to use all four slots on the motherboard.

Is it time to RMA?
 
I guess you already tried this, but try with just one stick of RAM? Maybe only one stick is faulty?

I did Nelly, I should add that at the moment both sticks are in slot 1 (Orange) and slot 3 (Black), I'm getting 8GB but obviously not dual channel.

It just don't like it when I move the stick from slot 3 to slot 2 where it is supposed to be for dual channel.
 
it wont boot from one stick in either of the orange slots?

you should carefully inspect cpu socket for any bent pins,and try loosening the cpu cooler/heatsink slightly
 
Okay,

I tried just one stick in all four slots, and this is what the results were;

Slot 1 (Orange) - Boots
Slot 3 (Black) - Boots
Slot 2 (Orange) - No Boot (Code 15)
Slot 4 (Black) - No Boot (Code 15)

Wazza, you definitely have a point about CPU pins, I'm going to check that next, sheesh, time to get the thermal paste cleaner out again.
