[SOLVED] Error code 55 on Gigabyte mobo

[notfunny]

I don't know why the hell I decided to upgrade my memories on my Asrock Fatal1ty 990FX Killer mobo, a couple of days after I installed the new memories CMZ16GX3M4A1600C9 (wasn't brandnew) the PC suddenly stop posting, I tested with other CPU and memories and still didn't post, so I ordered a new mobo Gigabyte GA-990FX-Gaming, it worked for couple of days and same like the previous one after couple of days after a restart it stopped working, the error code on mobo is 55, again on this mobo I tested with new CPU because I thought maybe the problem could be the CPU memory controller but it wasn't, I tested with new memory on different slots but nothing changed, reseted the bios, removed the battery, whatever you think.. but nothing changed.. my question is if the problem could be my first upgrade which was CMZ16GX3M4A1600C9 memories? because before that everything was okay! Can memories damage the mobo?
Could the problem be my power supply or the graphic card? are my mobos even dead?

I'm getting code 19 for a second and than stays on error 55.
Code 19 is Pre-memory South Bridge initialization started
Error 50-55 are Memory initialization error codes.

FX-8350
GA-990FX-Gaming - Bios version F2
Corsair CMZ16GX3M4A1600C9
AMD Radeon HD 7950

Thank you for your helps

The Corsair CMZ16GX3M4A1600C9 memory kit that you specified is a four piece DDR3 1600 MHz CL9. It is on the Memory supported list for that specific motherboard. So it should be 100% compatible with the motherboard.

Memory can fail. You can place that memory in another system and run Memtest to determine if it has a problem.

You can try various combinations of one stick of RAM to get the motherboard to post. But I would guess that since it is giving both memory errors that it is the motherboard that is the problem.

You can also switch out the RAM that is known to be working. That will test the motherboard itself.

From your post, you have tried both of those steps. I would guess that the motherboard is damaged.

The only way that I can think of that a stick of RAM could damage the motherboard is if the contacts were shorting out the motherboard dimm slots.

Normally if a stick of RAM fails it will just stop functioning. I haven't heard of a stick of RAM damaging a motherboard. And as above if the stick of RAM had contacts that were shorted the RAM would not function for several days. Shorting the dimm slot would damage the motherboard very quickly.


You also asked about the power supply. An otherwise working power supply can be inadequate for the system and would cause the system to crash or not POST. A power supply with excessive capacity would power the system just fine. The power supply will only supply the watts that the motherboard draws. For example, an 850 watt power supply installed on a system that only requires 350 watts is excessive (and a waste of money). But if the system only needs 200 watts at that particular moment, that is the amount of watts that will be supplied by the PSU.

There are things that could have damaged both motherboards. For example if the motherboard standoffs were not installed on the case prior to the installation of the motherboards, that could damage a motherboard. Another component that was installed on both systems could damage the motherboard.

A CPU with a damaged memory controller could cause memory related errors, but I don't know that they would damage the motherboard itself.

You said it was running fine the first few days, what were the memory timings set to? Were they set by a XMP memory profile?

Try clearing the CMOS again. Turn off the the power supply and press and hold the case power button for 10-15 seconds. Then unplug the power supply and wait for another 30 seconds or so. Then remove the CMOS battery for an 30 minutes or so (or longer it can't hurt). Then reinstall the CMOS battery and power up the system as normal.

That should clear any memory settings and reset the BIOS to the default settings.

Did the system boot up?

Thank you for your replies, I didn't change the timings or voltage manually but on both mobos I was enabled the XMP memory profile. I also cleared the CMOS as you suggested but the PC didn't post.

I would try switching the memory out. Can you can borrow some DDR3 to test the motherboard? The memory has a lifetime warranty, but I don't know if it is transferable (you said it was used memory). But you can try to get it replaced under warranty (they can only say no). Otherwise replace the DDR3 RAM.
