Tks. I got replies today from Overclockers UK, and Aria who both said they do not stock singles. Will have to rethink this one.
cheers
PS. Looking at intel and Crucial, max ram on this board is 16MB but must be in single,dual,triple interleaving. So by adding another 2GB to 4th slot on board will not really help.
Crucial do have the single sticks for abt £47. But I am probably looking for new 3x4GB kit.
