顯示卡 AMD RX 480 供電超抽？官方釋疑

[金大帥]

所以RX480會吸星大法!!

這只是AMD自己的滅火文章，reddit已經有人打臉了...

況且半打的測試網站都有點出這問題，現在reddit或是台灣的ptt都吵翻天了。

基本上應該是架構上的問題，預設頻率的峰值耗電*就不低，真的沒有那麼省，硬要做成單6pin，單6除了賣像好看外(讓你感覺很省電)，也是為了OEM廠商，大部分也沒有8+6或單8的PSU。

下場就是峰值耗電300W*可以從主機板抽了將近150W，完全不照規範，中低階主機板久了很有可能負荷不了，例如音效卡容易爆音破音就已經是顯而易見的。

970也有單6 pin的

There are some models of GTX 970 that only have one 6 pin plug

一樣會超抽!!

主機板超抽電的問題
等8pin的非公版出來就可以解決了

抱歉我並不知道勾表頭可以量直流電流
所以在此道歉

如果真的會讓主機板供電超過負荷
受害最大的應該不是消費者...應該是跟AMD合作的顯示卡廠...
有機會賣不好堆庫存跟返修率高大幅增加RMA成本;oq;

在別的網站有看到 國外己有超頻後主機板的PCI-E插槽陣亡的案例出現了!!

不是我要加火，我再使用技嘉 7970GHZ，跟MSI R9 280X 6GB，就壞過一張主機版ASUS P8P67，之後換MSI Z77A G41!!

2年多壞一張版子，這樣機率還好，覺的有超頻才會造成主板超抽，感覺買非公版會比較好!!

這個嗎?
有人在AMD論壇提到.PCI-E slot died with RX 480.並附照片...

https://community.amd.com/thread/202410
Processor: AMD FX-8350 @ 4.5GHz
RAM: 8GB Corsair Vengeance DDR3 @ 1600MHz
Motherboard: ASRock 970 Extreme4
GPU: RX 480 8GB Overclocked to 1350MHz core (no overvolting, stock VRAM speed)

等候AMD後續處理及說明...
目前看到的是...Official Statement from AMD on the PCI-Express Overcurrent Issue

AMD sent us this statement in response to growing concern among our readers that the Radeon RX 480 graphics card violates PCI-Express power specification, by overdrawing power from its single 6-pin PCIe power connector and the PCI-Express slot. Combined, the total power budged of the card should be 150W, however, it was found to draw well over that power limit.

AMD has had out-of-spec power designs in the past with the Radeon R9 295X2, for example, but that card is targeted at buyers with reasonably good PSUs. The RX 480's target audience could face troubles powering the card. Below is AMD's statement on the matter. The company stated that it's working on a driver update that could cap the power at 150W. It will be interesting to see how that power-limit affects performance.

"As you know, we continuously tune our GPUs in order to maximize their performance within their given power envelopes and the speed of the memory interface, which in this case is an unprecedented 8 Gbps for GDDR5. Recently, we identified select scenarios where the tuning of some RX 480 boards was not optimal. Fortunately, we can adjust the GPU's tuning via software in order to resolve this issue. We are already testing a driver that implements a fix, and we will provide an update to the community on our progress on Tuesday (July 5, 2016)."

看到正要回某樓被打臉的很嚴重阿,不知道在醉什麼,最近網路上p孩用語嗎?
不過有道歉就算了.....下次發文前功課最好還是做好再發文比較好...
