I ordered 4 x 1gb FB-DIMMs from the Apple store in my country and what I received were Samsung FB-DIMMs with a much smaller heatsink than the ones Apple USA is selling. So what I am wondering is if anyone has any experience with theses Samsungs? Will these work and not make the fans go crazy? Some info: This is what says on the package: 1GB FB DIMM, ECC 64x8,667MHz, Samsung On the stick itself it says: 1GB 2Rx8 PC2 - 5300F - 555 - 11 - BO M395T2953CZ4 - CE601 0634 I have seen these on some European websites: - http://www.biehler-online.com/catal...d=406&osCsid=6784b9e2767d7002d3a6da2fe3e69a6e - http://www.macdata.se/?view=details&prodnr=512/667FB/DIMM I hope someone can help... Thanks.
