Conclusion
The old adage of 'you get what you pay for' seem most pertinent here. I've attempted to demonstrate why running with strict memory timings, 2-2-2 in this case, is beneficial over more generic timings. Even running at the same MHz speed, strict timings do provide a meaningful performance boost. Just look at the Pifast, 3DMark 2001SE, and Quake III's results for confirmation.
The other advantage of specifying strict timings at lower MHz lies in the fact that the module should be stable at far higher MHz with slightly more relaxed timings. That proves to be the case here. Rated at 133MHz, the Mushkin module managed to surpass the 200MHz barrier, albeit with extra voltage and a CL of 2.5 clocks. The extra performance derived from running the Mushkin module at 178MHz (133FSB with memory at 3:4 ratio) gave us a significant performance boost whilst the processor clock remained fixed at 2800MHz.
The only problem that I have in wholeheartedly recommending this module comes from the fact that the memory market is now saturated with PC2700 and PC3200 memory. These memory modules guarantee a minimum speed of either 166MHz or 200MHz respectively, usually at the expense of timings. Having said that, this Mushkin module is perfect for those that want to stick firmly to FSB specification for the Athlon KT333 or Intel i845E motherboards, as it's rated at 133MHz with the most aggressive timings possible.
Highs
-
The strict timings make it the PC2100 module of choice
-
Integrated heat spreader adds a touch of class
-
Excellent packaging and aftercare
-
Manages to run at DDR-400 speeds with a little more voltage
Lows
-
Undoubtedly expensive for a PC2100 module, ~ £140 for a 512MB DIMM
-
A number of PC2700 and PC3200 modules are available with faster stock speeds
-
Difficult to get hold of in the UK
Overall rating 8/10.
