It doesn't look like you will get a buyer for the RAM at the price you want. You get brand new 1 GB Transcend RAM for less than what you want for second hand sticks, no matter how good the OC'ing potential is.
Buyers of new systems anyways won't be interested in DDR as it is outdated. All new systems are DDR2 now.
Even people who have DDR platforms won't be able to use your RAM to overclock anyways because they will already have some DDR RAM from before and that probably won't OC as well. Just to OC the RAM they buy from you would need them to sell their current RAM sticks.
