Since upgrading the motherboard recently I've moved to some lovely DDR3 and have these two sticks as spare. They've been used in my desktop at home since May 2011 and have caused me no issues whatsoever. Full spec is: Kingston 4GB (2x2GB) DDR2 800MHz HyperX Blu Memory Kit CL5 1.85V Non-ECC Unbuffered.
Looking for £20 + about £6 for delivery through UK Mail. Based in Bristol so can delivery to there and surrounding area.
