In this review, PCStats will be testing a set of new 512MB Mushkin PC2-4200 DDR-2 RAM modules, for a total of 1GB. These green single-sided DIMMs are wrapped in black aluminum heatspreaders, and fall into the PC4200 class. They are rated to run at 266 MHz with 4-4-4-12 memory timings, at 1.8V. The memory runs a bit conservatively considering it's Mushkin, but then again it seems like most memory manufacturers are being cautious right now.
