Hi,
I have bought few DDR2 800/1GB modules recently. My idea was to overclock them, but there is a problem hire - unfortunately none of them can reach 850Mhz (ddr2). I did some research on Internet and have found some interesting facts. For instance PQI 1GB DDR2-800 with PQD2648E25R chips can hit 800MHz at 3-4-3-12 @2.1V and 1066MHz - 5-5-5-15 @2.1V. The same DIMMs but with PQD2648P25R chips hit their limit at 860MHz on CL5. Both use expensive PCBs - Brain Power BP ML E186014 94V.
So I want to give another chance to my DIMMs before throwing them away. I intend to flash them with SPD from upper class modules produced by the same manufacturer. First pairs are 2 x PQI DDR2/800-1GB and 2 x SuperTalent DDR2/800-1GB.
Some help with finding SPD from PQI DDR2/800 Turbo 1GB and SuperT DDR2-800C4 1GB will be appreciated.
