New RAM issues?

[PSenapus]

Hello,

 

I have recently bought some new RAM for my system and I have been experiencing start up failures.

When I switch the computer on, sometimes it fails to start for 1 or 2 times and reboots, then resumes normally.

When the computer fails to start, the motherboard debug display shows 49 and then reboots.

 

What is this and how can I solve this problem?

 

System:
H440
Asrock Z77 Fatal1ty Professional

Intel Core i5-3570K (No OC)

Mushkin redline ridgeback 4x4GB 2400mhz cl10 (XMP)

Zotac GTX 780 OC
1 sata SSD, 2 sata HDD

 

Windows 8.1 hybrid shutdown is disabled.

Try booting with 1 stick of ram at a time. This will help determine if a stick of ram is failing(or not).

Hello,

Thank you for the help, but it wouldn't help me, here is why:

This issue only happens sometimes, especially the first boot of the day.

If I were to shutdown the pc now and start it up again, the issue does not happen.

I would have to use for 2 or 3 days the computer with 4GB of RAM, and the issue might not appear. And I need the 16Gb to work.

1) look up what that post code means for your motherboard

2) try 1 stick at a time

3)Memtest!

According to the motherboard's manual, there is no code 49. @_@

I am sorry I didn't include this info in the first post, I ran memtest86 for 24 hours and I got no errors. Rock solid apparently.
