There recently have been more DDR2 SDRAM related articles in the Memory section of our site, and quite appropriately so. The fact is the DDR1 SDRAM memory type just ceased to progress. JEDEC didn’t ratify any new standards since PC3200 and the manufacturers of overclocker-targeted modules do not focus much on improving the characteristics of their DDR1 products due to several reasons.
Firstly, no progress in modules is possible without appropriate DDR1 chips and the chip makers haven’t yet offered anything better than the widely popular Samsung TCCD and Winbond UTT chips whose potential is already nearly exhausted. And no advances are expected in this area since the chip makers have long switched to the newer, DDR2 type of SDRAM. Secondly, there is not much practical sense in getting higher than DDR600 because you have to overclock you entire system to enable this memory frequency which is not always possible. For example, you have to increase the clock-gen frequency from the default 200MHz to 300MHz to use DDR600 SDRAM in an AMD Athlon 64 computer. To do such overclocking, you need an overclocker-friendly mainboard and, in most cases, the option of reducing the CPU frequency multiplier below its default value. We must acknowledge that the recently released Athlon 64 processors on the Venice and San Diego cores allow using step-up memory frequency divisors which make it possible to use modules faster than DDR600, but such divisors must still be supported in the mainboard’s BIOS.
And anyway, a good idea can never die. Not so long ago we spotted overclocker-friendly memory modules with a fantastic marking of PC5600, i.e. DDR700 SDRAM! The modules come from PDP Systems, the owner of the Patriot Memory brand. The release of DDR1 SDRAM modules that surpass many DDR2 SDRAM ones in speed provoked much enthusiasm among the overclocking community most of whom stick to the DDR1-based Athlon 64 platform.
We just could not remain indifferent, either. So, we got a sample of the product and will now try to check its properties in this review. The main question we are obsessed with among others is how did the manufacturer manage to build a much faster memory module than the competing products out of the same memory chips?
