Patriot PDC22G8000ELK

Patriot’s PDC22G8000ELK modules are an offer for economical overclockers. Pricing them much lower than other DDR2 SDRAM modules intended to work at 1GHz, Patriot still managed to achieve quite acceptable characteristics. At their default 2.2V voltage these modules are expected to work at 1000MHz, although with “relaxed” 5-5-5-15 timings.

According to the manufacturer, the Patriot PDC22G8000ELK kit is meant for use with mainboards on i975X and i955X chipsets in the first place, but we had a number of stability issues trying to use it on our i975X-based ASUS P5W DH Deluxe mainboard. The memory was stable on our ASUS P5B Deluxe (with an iP965 chipset), though. So, Patriot PDC22G8000ELK modules is inexpensive but is not guaranteed to be stable on any mainboard you may want to use them with. This kit differs greatly from other memory modules in this review because it is based on chips from Elpida. On the other hand, Patriot guarantees that the modules can work at 2.3V voltage without a risk of damage.

Like all other modules from Patriot, these are equipped with traditional black-anodized aluminum heat-spreaders that are not flat but have a few, even though small, ribs. This allows the marketing people from Patriot to claim that their products provide improved heat dissipation.

The marking and default timings of the product are printed on the stickers glued to the heat-spreaders.

The SPD chip contains somewhat different info for the sake of better compatibility with mainboards.

This memory kit is inferior to the other kits in this review at practical use:

It is only stable at 915MHz with 4-4-4-12 timings. When you select 5-5-5-15 timings, the kit overcomes the 1GHz mark, but not by as much as we have seen in the tests of DDR2 SDRAM modules based on Micron chips. Note also that the frequency potential of the Patriot PDC22G8000ELK modules grows up along with their voltage.
