Idle Cycle Limit
Settings = Auto, 0-256 in varied increments.
From the DFI BIOS: “This BIOS setting specifies the number of memclocks before forcibly closing (pre-charging) an open page.” It appears that this setting is the maximum number of tries allowed for a page of memory to be read before arbitration kicks in and forces pre-charge once again for that page.
Slight Influence on Bandwidth/Larger Influence on Stability.

Idle Cycle Limit的設定值從0~256。
此值決定了 "記憶體在強制關閉預先充電的分頁空間之前，記憶體所有的循環週期數目"
換句話說，該值決定
"在調停器中斷/強制重新預先充電該分頁之前，該記憶體分頁可以被讀取的次數"
此值對於記憶體頻寬影響甚小，對穩定性影響甚大。

Suggested Settings for DFI: The Auto setting defaults to 256 clocks which seems to be overkill. If your RAM is lower grade----then I would stay with Auto. If your RAM is a step up, I would try 16-32 clocks. I had good luck with 16 clocks on BH-5. (Lower = Faster)

DFI板子的Bios預設是256，則顯得有點過頭了..(除非您的DRAM真的不怎樣...)
原作者建議此值設定為AUTO。
假若您的DRAM系出名門，我們建議設定在16~32 循環週期之間。
在BH-5，原作者很幸運的設定 16。固此值越小，記憶體傳輸效率越快。
