随着PⅡ产品种类的层出不穷,我发现同一种型号的CPU,超频性能不大相同。这同主板和CPU型号有关系,还同CPU上的二级缓存有关系。 CPU的二级缓存速度关系到CPU究竟能超到多少。首先,大家要清楚PⅡ二级缓存是以CPU主频的一半速度跑的。以前的Klamath233、266、300的二级缓存速度是7 Ns(纳秒),一般情况下缓存速度乘以缓存频率以不大于1000为好。Klamath233的频率最多能是多少呢?1000÷7×2=286。
With the proliferation of PII product categories, I found that the same type of CPU, overclocking performance is not the same. This is related to the motherboard and the CPU model, but also with the CPU on the secondary cache. The CPU secondary cache speed is related to the CPU how much can be exceeded. First of all, we must be clear P Ⅱ secondary cache CPU speed is running at half the speed. The previous Klamath 233, 266, 300’s secondary cache speed is 7 Ns (nanoseconds), and in general the cache rate times the cache frequency is no more than 1000. What is the frequency of Klamath 233? 1000 ÷ 7 × 2 = 286.
