只係今次不再似 Zen / Zen+ 咁 揀 ram die

三生石 2019-5-6 13:34:43 今代係有單獨i/o die,唔似之前咁經過ram再返入cpu
好耐之前發報會已經講過啦

你地係唔會係玩野,定根本無在意
明明呢個先係zen 2嘅特質
唔係淨講緊今代高左幾多0.幾ghz
而且今代zen2對ram嘅延遲比上一代zen+差
但佢重點係唔再咁ram,所以先冇咩所謂

Jacksjoke 2019-5-6 13:39:35 你都係要比足夠頻寬落2代IF總線

Jacksjoke 2019-5-6 13:43:39 When doing serious memory overclocking, it can happen that the Infinity Fabric can't handle the increased memory speed. Remember, Infinity Fabric runs at a frequency synchronized to memory. For example, with DDR-3200 memory (which runs at 1600 MHz), Infinity Fabric will operate at 1600 MHz. This is the default of Zen, Zen+ and also Zen 2. Unlike earlier generations, the new BIOS offers UCLK options for "Auto", "UCLK==MEMCLK" and "UCLK==MEMCLK/2". The last option is new and will come in handy when overclocking your memory, to achieve stability, but at the cost of some Infinity Fabric bandwidth.
