Z87 Pro Memory Issue

cdepth
Level 7
I just finished a new build with the Z87 Pro, but am encountering memory issues. I have 4 sticks of GSkill Ripjaws X RAM, for a total of 32GB. All four sticks have been tested, and work in the B1 and B2 slots, but I am unable to boot as soon as I put any sticks into A1 or A2. I have successfully installed Windows, and gotten the motherboard to recognize my graphics card when only using the B1 and B2 slots. I have not done any overclocking yet. Not sure if I should RMA, so any advice would be greatly appreciated.

Specs:

Asus Z-87 Pro LGA 1150
Windows 8.1 Pro
Intel i7 4770k
Corsair H110
Asus Blu-Ray BW-12B1ST
EVGA SuperNOVA 1000 G2
GSkill Ripjaws X Series 32 GB (4x8)
EVGA GTX 780 2784
Samsung EVO 500 GB

Edit:

The Q-Code displayed on the LED is 55.

Welcome to the ROG forums, cdepth.

Please check for me if your motherboard is running the latest BIOS. If not, download it from the Asus site to your USB pendrive and update it through the EZ Flash Utility in your BIOS.

Also, if this one 32GB kit? Or two separate 16GB kits?

I would assume that they are dual kits that you are combining as the X kits are for dual channel systems.

Please reseat your CPU cooler and follow the vendor instructions when you tighten the cooler. Uneven cooler can cause this.

First off, the RAM kit I bought was a four stick set (purchased off Newegg).

I updated to the latest BIOS available for the Z87 Pro, 1707. I'm still unable to boot up whenever I put any sticks in the A1 and A2 slots. However, the issues I'm encountering are a bit different now. Now, with XMP disabled, when I boot the LED goes through a bunch of codes, flashes 03, then the whole computer shuts off, before rebooting, going through the codes, and crashing again. Previously, I would encounter this issue when placing two sticks in B1 and B2, and one into A2. It seems though that the motherboard is getting past the 55 code now. The last code that is flashed now before the computer shuts off is 03.

As for the fan, I reseated it, and I don't think that it's the issue. My CPU runs at 19-22 celsius when idling.

Also, I've seen online that maybe I should try boosting my RAM voltage to 1.55V? Is this advisable? And how would I go about setting that up?

Could you link me to the product page please, I wonder if those sticks are previous generation XMP profiles, they have been giving some users problems when installed as the XMP profiles are different.

You can quite easily change the vcore for the sticks simply navigate down to the voltages and manually enter the same value as on the sticker on the memory.

I bought this set: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231569

There's a little sticker on the front of the package that says it's compatible with Z87. When I enabled the XMP, the timings and voltages for the two slots that do work seem to match the specs given on this product page.

Yip those should just work.

If you have reseated the CPU, after inspecting the socket pins for any misaligned and you have not found any. Then please RMA the motherboard.
