Does it comply with Intel's PC100 SDRAM Spec?
gezien en gehuiverd op deze
Ik heb alleen deze specificatie er uit getild, af en toe draait mijn maag een beetje, dus wil je alles lezen, ga dan naar Super7.
In a perfect world these specifications would have included a consistent system for marking the SDRAMs themselves to avoid confusion, but alias, not being in a perfect world, we are forced to deal with a plethora of markings that differ not only by manufacturer but even within individual manufacturers themselves.
Because so many of us haven't taken the time to decipher all of these product codes, we have forced ourselves into having to rely on reseller's and store clerks' veracity to get PC100 modules that will correctly meet our needs.
And because most of them were as ill-informed as we or were less than honest, we, endusers, suffered the consequenses, buying system memory that was not as fast or as capable as we had expected. Even just a month ago there were all sort of claims from the industry, some vendors offering 8ns,7ns or even 6ns parts, when, in fact were offering only 10ns parts!
Problems are not limited to vendor mis-information though. Module manufacturers can take these chips marked with"-7" or "-6" and the like (really-10ns rated) and put them on a DIMM together with an SPD that instructs the system to run the module like a true -8ns. This results in a DIMM that, while it may function correctly, is already technically overclocked, making enduser overclocking impossible, and in systems with more than one module, can cause all sorts of compatibility problems.
Although 10ns components can function at 100MHz, when attached to the DIMM module they will have lost some of their performance abilities due to a number of factors (i.e. trace inductance and resistance, solder joints, terminal resistance etc.) therefore true PC100 compliant DIMMs have to be made up of 8ns(125MHz) components to compensate.
DID YOU GET THAT?
In order to be Intel PC100 compliant; DIMMs have to be made up of 8ns(125MHz) components!
