Azrock Z77 Fatal1ty Performance Code 55 RAM Upgrade Issue

[yodeebo]

Hey guys,

I recently bought new corsair vengeance 2x4gb ddr3
However, my computer has issues recognizing them after installation.
With 4 sticks installed causes code 55 and CPU shuts off
With 3, the original 2(2x4GB) are still recognized, but not the new 1.
With the 2 NEW ONES ONLY INSTALLED, the computer shows code 55.
I swapped the ORIGINAL 2 around different slots, powers on as normal.
The 2 original I have same specifications exception their versions differing
Original: 8.16 New:8.23

The new ram may be bad...

Did you try a CMOS reset? That should be done when changing out ram

Make sure you have them installed in the right order. From left to right: red > gold > red> gold OR gold > red > gold > red

If that doesn't work then you probably have a compatibility issue since the 2 pairs aren't identical. The specs appear to be the same, but the model numbers are different.

The motherboard user manual says on page 22:

This motherboard also allows you to install four DDR3 DIMMs for dual channel configuration, please install identical DDR3 DIMMs in all four slots.

Reset the BIOS/CMOS...

...be sure you have updated to the latest BIOS on that motherboard.

The motherboard user manual says on page 22:

This motherboard also allows you to install four DDR3 DIMMs for dual channel configuration, please install identical DDR3 DIMMs in all four slots.

That doesn't explain why they don't work alone, however.

With the 2 NEW ONES ONLY INSTALLED, the computer shows code 55.

RMA time

this Thread is from 2012, so you wont be able to ask the original poster about it, but it is a exact same code result as yours, and a similar board too, also after RAM upgrade iirc...

looks like @OneMoar solved it in 2012...

"Problem solved

Hey you guys are right. The problem was with the mobo socket,
I took my proccy out of mobo today. To check the cpu socket. What i found was a bent pin.
I carefully made the pin straight. Now all four ram slots working fine.
No i am running my rams on slot a1 and b1 .

Thanks a lot guys.

For everyone who planing to buy Asrock z77 Extreme :
I searched online everyhwere. Many reporting that mobo having faulty ram slots. So beware."

I don't quite understand how the original poster of that thread came to the conclusion that it was an issue with as rock motherboards as he freely admits in the above quoted post that he removed his processor and found bent CPU pins which is his doing and no one else's but whatever

I attempted it with 3 + 4 total sticks.
Having 4 in still causes the computer to shut down with code 55.
But I was able to load the 3rd stick.
Still does not answer why I cannot use all 4.
I even swapped the 2 sticks around to maintain 3 and it worked.
So I don't think it is the new sticks being bad.

@yodeebo
have you checked the CPU pins ? that was the cause of this Exact issue on a similar board..... worth a look. especially since its almost an exact clone of what is happening to You now.

good Luck

try one stick at a time

Had to fix a similar problem once with my ASRock Z77 OCF board - Had a single pin in the socket that was bent just enough to cause it to do this. Carefully bent it back and it works as it should now. Using too much mounting pressure on the CPU is what caused my issue and even now if trying to mount a waterblock it tends to act up but with a standard cooler (air) it doesn't do it. I also believe when I set the waterblock on it runs into a problem with the mounting pressure not being equal across the socket making it have a pressure sideload, that is more on one side than the other but the aircooler doesn't have this problem since it's pressure is spread out equally across the CPU's surface once fully mounted.

Check the pins, you'll probrably spot one that's "Off" and even if it's barely noticeable it can cause it - Mine was like that and took some careful observation to find it but once I did I was able to get it working again.
