2010 台灣隊顯卡精進計畫開跑通知

[oegg]

980X ES OC 4.0G 跑 Linux 1% 大約 23 分 1 秒,
看來 980X 6C/12T 還是要跑 native linux 才能完全發揮,
小弟經費有限只能找 ES 來跑, 大約 不到 20K, 市售版的 980X 還是太貴買不下去...

支持直接跑native linux，
我的i7也等待下次Work完後改用Boot Linux CD的方法來跑~

 

[OverFold]

小弟也認為4C/8T(或以上)的i7平台在F@H運算上性價比較高，
可是當你以GPU_Console見到Fermi可以數十秒跑1%那種快感
(i7 BigAdv 1%要花半句鐘~~)，即時感受到性價比原來都不算得上甚麼.........

 

[kazama]

在不涉及平台更換的前提下，提出兩項CPU昇級建議:
1. i5-750昇級i7-860
2. i7-920/930昇級工程版6C/12T

若有熟悉工程版CPU市場的隊友提供價格實在信用可靠之商家資訊，
應會有更多i7-920/930用家隊友昇級6C/12T bigadv運算。

980X ES OC 4.0G 跑 Linux 1% 大約 23 分 1 秒,
看來 980X 6C/12T 還是要跑 native linux 才能完全發揮,
小弟經費有限只能找 ES 來跑, 大約 不到 20K, 市售版的 980X 還是太貴買不下去...

如果以 980x OC 4g + x58 +低階顯卡 以80plus 銅牌以上的psu來推，
整體耗電量大約是300w左右，可以達到ppd 43000...

不管是效率還是單機產分完完全全是殺爆Raziel前輩之前的9800gx2 四卡機.........
如果是以f@h專用機來說應該是一時之選了:)

而且還不用管麻煩的9800gx2散熱問題.



另外昨天收到oegg前輩的勸敗私訊後，
開始考慮要把自己的跑分機砍掉重練，轉進bigadv...
要是在native linux 下也能兼跑GPU Client就好了，

 

[ShinnShinn]

除了砍掉重練的另一個選擇是把775平台 9800GX2 雙卡機跑分機 升級成GTX470雙卡機，
除了2張GTX470的價差外，還要考慮新PSU的價差.
而且沒看到GPU3 Client實際效率也還未知孰優,

還是等GPU3 Client出來後再決定升級方向好了.

NEWS Support Fermi/GTX4xx

Vijay Pande has posted some more information about the pending support for nVidia's Fermi/GTX4xx cards in Folding@home. It has not been a trivial fix to make the cores work on these new cards, and a new client will be required to support the cards, as well as some behind-the-scenes changes to the Pande Group's software.

The upside of this extra effort should mean that the new core will utilise these more powerful cards far more effectively than the current cores would have if they worked on Fermi. However as a result support for the GTX4xx series is still a few weeks away, whilst the new code undergoes thorough internal testing, so your cards will need to remain idle for a little longer. Or maybe give you an excuse to dig out those dust-covered PC games.

再過幾週就有Fermi/GTX4xx 的支援了, 目前還在等正式測試, 不過 對岸的離線測試已有預測

GTX480在底層運算力可能有GTX285的五倍, 故達 40,000PPD. 雖是先聽爽的, 用的是nvidia

給的工具, 最終還是要F@H官方GPU client跑了才算數, 也難保Pande lab會不會調整分數權重

不過至少又燃起了一些希望, 效率可望跟bigadv平起平坐, 就拭目以待吧~ 隨時有新的情報也請

大家轉貼發表. 相信顯卡還是很多人有興趣的.

 

[OverFold]

「GTX480在底層運算力"可能"有GTX285的五倍.......」

若然Fermi"可能"達到預期的F@H運算水平，預算充足的話"可能"我的750W Server Power
也不介意添一位新Partner來消消電，如此一來Daily Production再翻一翻"可能"飆上120,000PPD~~

目前...Q6600+9800GX2...
另外一台是Q9400(OC3.2G)+GTS220...
後來還是自己另外帶一顆850W的POWER去學校操了
不然ASUS套裝電腦附的台達300W要上9800GX2...應該會掛掉吧ORZ
至於Q9400是新電腦應該會陪伴我一直到暑假+往後2年
而Q6600暑假就差不多要歸還了(差不多到8月...不過他24*7也跑了應該有幾年了...)
有可能到時候會變成Q9400+9800GX2吧...
話說
9500GT和GTS220哪一張比較好啊???

GTS220吧~ 再怎樣也贏在製程較小, shader數多16個, F@H與效能也都稍贏95GT一點.
