the memory technology that you’ll find in most of the electronic devices you own

此記憶體技術已存在於許多您所擁有的電子裝置中

like your desktop or notebook computer or game console,

例如您的桌上型或筆記型電腦，以及遊戲主機，

and even some very important ones you don’t own like the servers that power websites

甚至在一些雖然不屬於您，卻對您非常重要的裝置－像是網站的核心伺服器

and services like Facebook or Dropbox.

Physically a DDR4 module probably won’t look that special to you...

當您看到 DDR4 模組時，可能不會覺得有何特別之處。然而，它確實有些細微的不同之處。

However, there are some subtle differences.

DDR4 RAM 無法向下相容於 DDR3 主機板，反之亦然，

DDR4 RAM is not backwards compatible with DDR3 motherboards and vice versa,

因此為了避免誤裝錯誤類型的記憶體，凹口的位置已經做了調整。

so the notch has been moved to prevent accidental insertion of the wrong type of memory.

相較於以往的 240-pin，現在的模組有 288-pin。

Now instead of 240 pins, each module features 288 pins.

而為了增加強度和電觸點，PCB 底部的形狀增加了一個微小的弧度。

And finally to improve strength and electrical contact there’s a slight curve in the shape of the bottom of the PCB.

除了實體上的差異之外，技術上也有所不同。

So nothing ground breaking... No, it’s what’s UNDER the hood that’s interesting.

那麼最新的第四代 DDR 究竟具備哪些前一代 DDR3 所沒有的技術呢？

So what does this new fourth generation DDR bring that the previous one – DDR3 – didn’t?

以下是幾項新的特色。

Actually more than you’d think.

首先是更快的速度。

First up is improved SPEED.

DDR4 的基本速度為 2133MHz－這屬於相當高端的 DDR3 所有

Thanks for that.

而且按計劃速度還可高達 3200MHz 以上！

DDR4 STARTS at 2133MHz – which would be fairly high end for DDR3

同時各個模組僅需 1.2V 即可達到此表現。

and has planned speed increases that could take it well beyond 3200MHz!

這也造就了第二個好處－節能。

and this is while requiring only 1.2V per module.

DDR4 相較於 DDR3 可節省最多達 40% 的耗電量。

Which leads to benefit number two – power savings.

當您使用桌上型電腦時，這個優勢可能看似並不突出，

DDR4 is more efficient that DDR3, consuming up to 40% less power.

但它將可以明顯提升您筆記型電腦的電池續航力。

This is something that might not seem like a big deal in your desktop PC,

對於行動裝置來說，任何耗能上的改善都至關重要！

but let’s talk next time your notebook shuts down due to low battery when you were 4 seconds from submitting that homework assignment!

記憶體容量更有了卓越的提升

When it comes to mobile devices, every little bit counts!

由於 DDR4 支援更高密度的晶片和堆疊技術，因此使單一記憶體模組

Speaking of bits – memory capacity is poised to go through the roof

可以在不久的將來就達到 256GB 甚至 512GB 的容量！

due to DDR4’s support for higher density chips and stacking technologies that will allow for single memory modules

DDR4 不僅在效能上突破了以往存在的界線，在可靠度上更有了最為顯著的改善。

with capacities as high as 256 or even 512 gigabytes in the not-so-distant future!

在可靠度上更有了最為顯著的改善。

But... pushing performance past existing boundaries into new territory would be for nothing if it wasn’t reliable...

經由改善的循環冗餘檢查、晶片上「命令和位址」傳輸的同位偵測、

and that’s where DDR4 actually makes some of its most significant improvements.

以及加強的訊號完整性，DDR4 是目前最為可靠的 DDR。

With improved cyclic redundancy checks, on-chip parity detection of “command and address” transfers,

因此而造就了 Kinston 的 HyperX Predator 模組。本產品的效能已針對使用者需求而預先最佳化。

as well as enhanced signal integrity, DDR4 is the most reliable DDR yet.

只要輸入一組設定，就能夠開啟 XMP 設定檔。

Which leads into Kingston’s HyperX Predator modules. Their performance is pre-optimized for you.

它已針對 Intel 最新的 X99 平台最佳化，能夠和您最新的 Core i7 6 核心或 8 核心 CPU 完美搭配。

Key in one setting to turn on the XMP profile and its off to the races.

最後，本產品擁有黑色版的 HyperX 招牌大尺寸散熱片

They’re optimized for Intel’s latest X99 platform so they’re a perfect match for your new core i7 6 core or 8 core CPU

因此非常適合用於任何 X99 主機板。

and finally they have HyperX’s signature tall heatsink inb lack

謝謝您收看此有關 DDR4 技術的影片。

so they’ll complement any X99 motherboard perfectly.
