FAH 硬體及客戶端綜合討論 (part 2)

[Raziel]

超很大的話， -bigadv -smp 8會不會比較好？
smp 7+560，smp會掉不少分，而且圖形處理變慢，windows會不太順，廢熱也變多

單就每瓦效益來說 當然是純SMP最優. 但是要看總產分的話, 560至少加一萬多分, 少個1/8的SMP

總合還是加跑560較高(也較耗電). 玩game時,請關閉GPU3 client, 顯卡閑置時再跑即可.

我自己不管是用x58或是sandy bridge跑SMP(空一緒)+GPU都不會有什麼windows不順的問題,

至少自己感覺還ok. :MMM:

現在560Ti的PPD有1W3左右
可是SMP好像罷工了...

接不到任務....

等等.....有錯誤訊息, 任務封包太大.;x; 這不是沒任務可接, 而是你沒設定收大任務封包.;oplc;
你把SMP client用-configonly這個參數重新去開啟初始設定流程
去看 "Acceptable size of work assignment and work result packets."
這一項設為 "big" 應該就可以了.

bigadv 30分鐘1%, 這PPD可能已經贏了90%的人, 用有超頻的2600k來跑這應是正常的數值~

你哪邊的工具看到30%?

 

[littlehama]

停留在29~30名一段時間，送修8800GTX後就都跑SMP了，繼續支持F@h！

 

[OverFold]

我的GTX460送修一整個月終於通知我明天可以取回，不過意外地768MB版無貨，
換來的是一張全新GTX460 OC 1GB RAM版本....如此意外的收穫看來這一個月來也算不上白等啊！~~

 

[xs910203]

發現一個很嚴重的問題!請有跑GPU3的人注意囉~
6.41最新版本GPU3跟SMP一起跑GPU使用率沒辦法到100%，分數會低的可憐(GTS450超頻跑PPD才2000多分...)要把CPU的優先權調高GPU使用率才會正常
6.32版本則沒有此問題，雖然優先權預設都是最低的可是不知道為什麼就是有這個問題
所以強烈建議大家不要更新新版本，已經更新6.41的趕快換回舊版本...以免分數損失慘重

The SMP clients version 6.34 binaries are now posted on the high-performance download page:
http://folding.stanford.edu/English/DownloadWinOther
They can be dropped into a working FAH installation, but it's always safest to update between work units.

There are several small changes involved, but especially support for new SMP2 cores (A5) that will be released in the near future.
