I don't know if you want to try this, but you can increase the voltage to the RAM. Several have suggested 2.1V especially if you want to do some OC runs. Since that RAM has heat spreaders, you should be safe to see if it cures your POST issue.
In my system I have 2x2GB sticks of budget Corsair memory and they run fine at 2.1V. YMMV, yadda yadda.
