defspace_ meldt dat bij 3D Spotlight een review te vinden is van PC133 geheugen, HSDRAM, gemaakt door Enhanced Memory Systems'. Ze zijn er erg over te spreken ondanks het feit dat de het geheugen niet hoger dan 143 MHz kwam met 2:3:2 als clock timings (150 MHz op 2:2:2 moet kunnen met een Mushkin reepje):
I've been hearing from a lot of people the question of "Why should I choose HSDRAM for my system"? It may be true that another brand of memory will take you to the bus speed that you want, but when you do that it's like a gamble. You may never know what speed you can get from certain brands of memory chips until you plug it into your system.
With HSDRAM, your pretty much guaranteed certain memory speeds. This is why a lot of people choose to purchase the EMS HSDRAM. They know what to expect when they buy the memory.
[...] In a more technical view, HSDRAM incorporates very sophisticated memory timings to reach these speeds. HSDRAM is a higher performing version of the SDRAM standard. HSDRAM offers a lower latency and a faster clock access time than regular SDRAM.
The HSDRAM has the much touted 4.6ns clock access time to give greater performance and stability at the 133MHz memory speed. Most of the other PC-133 memory that you buy, will most likely come with 3:3:3 suggested clock timings, HSDRAM PC-133 comes with 3:2:2 memory timings.
