i think there is "general" supply shortage., check for example newegg, u wont find them for sale, also geizhals.at returns eshops only to find out a moment later that all are zero stock. who knows maybe OCZ got scared of ddr3 elpida-chip deaths.. and didnt want to repeat this in ddr2. I recently bought the Gskills 8800 pi 8gb (4x2gb) and they behave like being with elpida chips.. (1200 5-5-5-15 trfc 60 with 1.89volt (minimum volt on DQ6) and almost zero scalling with voltage), u should try to find a "fresh" stock-ed 8800 pi 4gb kit , (i say fresh cause older kits were reported to top at 1170 and weren't elpida) and hope to have similar chips like that used on 8gb kit.
