1 Samsung PC800 2GB vs. OCZ SLI DDR2 PC2-8500 1GB

Hey guys, what do you think is better for me. I have an HP OEM Asus IPIBL-LB motherboard supporting 667/800MHz RAM. I have the 6GB of Samsung PC800 in 3 2GB pieces, taking up 3 of the 4 RAM slots. For the last slot, should I get another 2GB of the exact same Samsung RAM or get a stick of OCZ DDR2 PC2-8500 1GB. The OCZ is too fast for the motherboard, bieng 1066MHz while the motherboard supports 667/800MHz, lowering the RAM speed. The OCZ SLI RAM is overclockable since it has it's little heat spreader case, and it has 5-5-5 timings, being decently good. So, OCZ or Samsung? P.S. Should I take out all of the 6GB and put in 4 1GB OCZ to fill all slots?
