1)DDR3管脚IO的分配强烈建议通过Vivado软件例化DDR3 IP核验证FPGA IO分配的正确性! 2)如果DDR3所在的BANK上有其他外设IO,也要一起验证IO,确保满足IO bank电平兼容性。 DDR3的 CLK_P/CLK_N时钟建议放置在FPGA芯片_SRCC或者_MRCC专用时钟管脚上,以保证时钟最佳性能。DDR3地址信号及控制信号放在DQ临近
注意示波器的探头和示波器本身的带宽能够满足测试要求。 测试点的选择要注意选到尽量靠近信号的接受端。由于DDR信令比较复杂,因此为了能快速测试、调试和解决信号上的问题,我们希望能简单地分离读/写比特。 此时,最常用的是通过眼图分析来帮助检查 DDR 信号是否满足电压、定时和抖动方面的要求。触发模式的设置有几种,首...
Each generation of RAM increases speed and frequency while decreasing power consumption. Since computer hardware is all connected and interdependent, this can lead to speed increases in other components, too, which is why upgrading your memory is a great way to fix a slow computer. Since the dif...

I got a 4790k overclocked @4.7ghz which ill probably push further with my new cooler which will soon arrive. The problem is that my ram at 2133 mhz, and there was a significant jump in cpu benchmarks scores compared to 2133 mhz and 1866 mhz (stock speed
we are talking about the speed at which the memory controller access's reads and writes from one 64bit block to another. When you see ram timings, they are generally represented like this: 9-9-9-24 or CL- tRCD-tRP-Tras (See below) there are more advanced ram timings, but these are...
