As the title says, I have 2 512mb sticks of ram, ECC buffered.

Labels on them state exactly this:

512MB 1Rx8 PC2-5300F -555-11

PC2-5300 CL5 ECC DDR2 SDRAM FBDIMM

Ordered the slightly wrong model for an HP Proliant Server (Meant to order the E rather than the F) But had opened it so cant return it. Otherwise it is brand new!

Selling for $228.84 (Same price I purchased it for) + Shipping.
