ASUS Impact VII Memory Q-code error 55 (I've tried everything!)

[TreesOnTheBeach]

Hello everyone.

I put together a PC (first time in 20+ years) a few months ago and everything went smooth except that I'm getting this q-code error. I can fill channel B with either memory stick, and I get 8 GB of functional RAM. When I put any chip in channel A, I get the Q-code 55, which is "Memory not installed" and the system won't boot. I have tried this with two different sets of memory chips (different manufacturers), both behave exactly the same way.

Here's the really weird part... I have taken the system apart 3 times, tried different memory, and even a replacement Impact VII board, and get the same results each time! How can I get the same result with different memory AND a different motherboard??

I have breadboarded it with only essential components, and still get the q-code 55.

I'm boggled. Hope someone out there familiar with this issue can give me some advice. I'd really appreciate it.

What CPU cooler? What CPU?

 

[smorizio]

have you use thr asus flashaback port and placed the newest bios file on the mb??

Thanks for the responses, guys. I do have the latest motherboard BIOs. The CPU is an i7-4790k and the cooler is a Corsair H100i.

When no chip I used worked in channel A, but they both worked in channel B, I assumed channel A was just not working. But when I received the replacement motherboard, it acts exactly the same way. I really don't know where to go with troubleshooting. Hope you guys have an idea or two. Thanks again for responding.

Try testing the board outside the case, only CPU, CPU cooler and single RAM module in channel A. See if still 55.

Yeah, did that with both motherboards... I still get q-code 55.

Then I suggest removing the CPU and checking the socket. If no bent pins, I'd RMA the CPU.
Try also testing with the stock Intel cooler.

Thanks, alexoiu. I have not tried with the stock cooler. I will give that s shot next, then double-check the PINs on the CPU. Man, this is crazy.

OK, please post back the result.

Will do. Thanks again for the advice.

Sorry my English is not good !!! I write from Argentina !!! I have the same problem with my error 55 pc. The pc is new, with all new components, only 3 months of use. I have an i7 4790k + asus maximus ranger VII + Cooler Master Hyper 612 pmw + 2x8 GSkill 2400. ram. I have seen that several have had the same problem with Asus failed 55 mothers (ranger, hero, impact) so I think the problem comes from there. Thou shalt have solved? As you do that? Any help is appreciated !!! Cheers!!!

Try testing with single RAM module each slot. See if 55 in each case. Test each RAM module.
