RAM cold boot issue

[xFluing]

I have this Athlon x4 860k system on an MSI A68HM-E33 (V1) motherboard. For the longest time, I've run this dual channel 4GB setup with some cheap 2GB modules (running at 1.5V, pretty standard), fast forward to a few months ago when a friend gave me two 4GB modules (total of 8GB), a Corsair XMS3 set (rated at 1.6V), however after putting it in I started having issues booting with it, even with XMP on (which made the RAM run at the rated 1.6V), I then realized I couldn't run dual-channel anymore, not even with the old 4GB kit.

 

The corsair kit would just refuse to POST (and RARELY if it POSTS it only shows 4GB, but board explorer still sees that both slots are populated), while the old 4GB kit would result in the monitor showing artifacts that would go for about 3 rows then cut off in the middle of the next one, so now I'm stuck in a single channel 4GB stick.

 

Is there a way i can fix this? Did I burn off my second DIMM with this ram?
