受了咒後的藍寶石-HD7970,好一點

本帖最後由 polarhei 於 2013-5-8 12:38 編輯

今日去代理取回疑似人為損壞的顯咭,我問要畀幾多,代理說因為不是人為損壞,故不用付。有人買了7770,用了三日出事,按此事,估計供電部份出事,才會如此。

收咭前,先以furmark,全速煲約一百分鐘模擬計數情況。

之後,返回挖礦




可能有人問,為何7970以675MhZ操作?因為要考慮每日多少仙,還有效率。完整啲就會好啲,故我不信中階,只信入門和進階。兩仙乘百,估計每日有二十四港元進帳。

The 675Mhz is used for stable test before Overload a little,I have powered that up, using 1175Mhz Core, auto memory tune, It loooks like I have additional card. (one 7970 and one 7750)

Tahiti就是7970。

純粹是價錢問題而已。不過,價格那麼低,可能有較多次貨。

打機不是用這個數值。我只是在測試穩定值而已.打機會用全速。

也許詳細說發生了甚麼事。Sapphire近期啲貨,要另外駁電的好睇彩數(用了7990個供電組後,也許好一點,真的8-pin加6-pin)。價格按其他人說,只是第二平。我今日嘗試打聽行情,尤其用sapphire,有人用7770打機,用了三日後出事。相信是供電出事。我的情況也是相若。因此,若選擇了sapphire的話,建議謹慎一點。

DVI is not easy to out of order. Perhaps the power module for external. I have received the defective design. I also have known that there is a person, saying using 7770 (with external power in), out of order after 3 days when playing 3D Games.

Good, Then you may know there is a method to help you on property issue (USD 500,000 At least) as some people agree the concept, then invest (actually, these people are facing high taxation rate problem, In france, 75%)

收到翻新貨? 我就沒有了,但我發現張咭用少咗電,同樣7970. 我在四月中買的, 與官方7990的發布時間好相近. 故障後, 代理把我張咭送去生產商檢修. 等了十四日收回. 我收回後發現, 因為7990官方已經定了形, 故單晶片版本順便"升呢", 性能冇變,但用電量少過之前, 因為我手上沒有量度用電量的裝置, 故實數不知,只知道滿載時的用電量已經在300W內.

但合理

It is no easy, Perhaps the previous design has higher chance to. Now the Sapphire has used newer one which is mainly from 7990 Offical design, the 500W at 1000Mhz core  so the power module is not easy to get failed as the design now is within 300W (75+75+150)
P.S More people select this one as the card is quieter than others with same condition (non aqua).
