Memory stick becomes unusable after OC.

Recently I've been playing around with my Athlon x3 450, trying to overclock it as high as possible. So I crank my fsb to 250 mhz, while keeping Northbridge and RAM frequencies at their stock values ( 2000 and 1333 9-9-9-24). CPU frequency is at 4000 mhz. With thesechanges, I am able to boot my computer and start Windows, but for some reason one of my 4 gb RAM sticks becomes unusable, and both bios and windows report 4 gb physical memory instead of 8 gb I have installed. I tried to move my sticks around from the blue slots to black spots, but the problem persisted. When my cpu isn't overclocked so high, both sticks work.
So, is my hardware faulty, or there is another cause for RAM reduction ? Specs are: M5A88 V-EVO mobo, Corsair 2X4GB 9-9-9-24 1333 dimms, Athlon II x3 450 CPU with Cooler Master heatsink. Before you suggest, that the memory loss can be due to tight heatsink adjustment, I wanna say that same thing happened with stock AMD cooler on as well.
Any ideas ?
