SimpleTech Nitro PC4000
 

Overall, we were very impressed with the packaging and the distinctiveness of SimpleTech Nitro PC4000 modules. To be frank, even after reviewing memory modules with LED lights and mirror heatspreaders, I find that the Nitro with blood-red PCB and gold coloured heatspreaders sets it apart from the rest. And needing only 2.6V to do 250MHz is simply amazing. Not everyone out there can afford or have a super overclock-able motherboard such as the DFI LAN Party NF4 series. Being able to run DDR500 with just 2.6V ensures that the modules will have longevity and run much cooler than those running at 3.0V and above.

Good but not good enough for an AMD system I think.

If you have AMD you want the higher FSB you can reach as close to 2-2-2-5 at 1T, as you can.

These sticks look great for Pentium systems though!
