OCZ is one of the most well known manufacturer of enthusiast memory. Recently they have introduced their XTC line of heatspreaders which are engineered to keep temperatures of the memory down, even when overclocking. The PC2-4200 Gold XTC offer superb overclocking, even at stock voltage. We found that the default timings of 4-4-4-12 can be tightened a good deal without losing much overclocking headroom.
