Instability with tactical tracers on gigabyte mobo

[ Edited ]

My current rig is running a Gigabyte 990FXA-UD3 (rev 4) with an AMD 1090T Phenom 2 CPU.  When I first built the system a few years ago I originally purchased Crucial Ballistix Tracer ram (older style with colored heatspreaders), 4x2Gb sticks (BL25664TR1608.16FF) which work flawlessly.  Well in a recent case upgrade I changed my system accents from red to blue, and figured I would get the matching ram and pass this ram to my wifes new machine.  The same type of ram in blue is no longer available as the line has been replaced with the newer Tactical Tracer series.  So I purchased 2x4Gb sticks (BLT4G3D1608DT2TXOB). 

 

The system started up fine most of the time, but alot of instability was noticed afterwards, programs I had used for months were suddenly crashing randomly.  So I downloaded and ran Memtest which kicked back alot of errors, mainly in test #7.  So after trying a few settings in BIOS (including XMP) I resorted to RMA.  Crucial got me 2 replacement sticks in good time and hasslefree, during which time I reverted to using 4Gb of the old ram which still performs perfectly.  Now with the new ram back in the machine the same problems are back.  I have tried to slow the ram back down below 1600 but with no improvement.  Currently I reset my BIOS memory settings back to optimized defaults and then activated the XMP profile. 

 

In a perfect world I would  love to see this ram stable at the rated 1600.  But right now I would settle for just having the new ram stable and running clean. I have some reports that might shed more light on the current settings.
