Memtest86打敗了我的記憶體最佳化
自從A-DATA DDR 400 CH-5 入手以來一直跑420 Mhz@ 5-3-2-2
AMD XP 1700+ oc 2200Mhz (210X10.5) 一天心血來潮測個Memtest86 test 5一測pass 2出現一堆錯誤 好吧.....那降至400 Mhz@ 5-3-2-2再測 test 5的pass 6又一堆錯誤 再進Bios調記憶體參數 400Mhz By SPD 8-3-3-2.5 再測........又出錯 pass 25兩個錯誤 這時心情很沮喪，正常頻率400 Mhz By SPD竟過不了 於是花了一天的時間，在兩百外頻的堅持下嘗試各種記憶體參數 終於....以400 Mhz@ 8-4-3-2.5 (cpu 200X11=2200Mhz) 通過了test 5八小時 test 8八小時和 All test (1-11)的測試 但CPUMark99降了6分 Super PI多了一秒 唉....心中感慨萬千 算了，穩定最重要 不然哪天要跑數據分析出錯就得不償失了  |

memtest86出問題不見得一定是RAM掛了
記得我曾把某套Adata DDR400 256mbx2 在某8RDA+上200外頻...最佳化測memtest All test...近8hrs...完全OK! 結果換CPU,另一張8RDA+...但同一套ADTA DDR400 256mbx2 立刻在test 5出狀況.... 但第二套CPU+MB卻成功測完創見DDR 400 256mbx2...5hrs OK! 無解! 現在我都是比較關心整體組合跑Prime 95是否>4hrs...比較要緊! |

memtest86內的readme.txt提供參考!
14) Known Problems ================== Sometimes when booting from a floppy disk the following messages scroll up on the screen: X:8000 AX:0212 BX:8600 CX:0201 DX:0000 This the BIOS reporting floppy disk read errors. Either re-write or toss the floppy disk. Memtest86 has no support for multiple CPUs. Memtest86 should run without problems, but it will only use one CPU. Memtest86 can not diagnose many types of PC failures. For example a faulty CPU that causes Windows to crash will most likely just cause Memtest86 to crash in the same way. There have been numerous reports of errors in only tests 5 and 8 on Athlon systems. Often the memory works in a different system or the vendor insists that it is good. In these cases the memory is not necessarily bad but is not able to operate reliably at Athlon speeds. Sometimes more conservative memory timings on the motherboard will correct these errors. In other cases the only option is to replace the memory with better quality, higher speed memory. Don't buy cheap memory and expect it to work with an Athlon! Memtest86 supports all types of memory. If fact the test has absolutely no knowledge of the memory type nor does it need to. This not a problem or bug but is listed here due to the many questions I get about this issue. Changes in the compiler and loader have caused problems with Memtest86 resulting in both build failures and errors in execution. A binary image (precomp.bin) of the test is included and may be used if problems are encountered. |

但我跑DDR 420Mhz@ 5-3-2-2
prime95十二小時是沒有錯誤的 卻過不了Memtest86 是否Memtest86對記憶體的測試比Prime95嚴苛?? |

這句無法回答! ...只能說請相信Prime95! 另!上篇readme.txt中藍色文字你有閱讀嗎? |

那段藍色的說明
是很好的建議 Mem86只是單純的丟pattern進去測試 我覺得這反而是隔離其他系統元件的好方法 |

到底怎樣才能把記憶體最佳化呀?
我的記憶體的分數都好低呀(用SiSoftware Sandra測出來的分數低到不行...還是雙通道的哩....埃....)有大大可以跟我說明原因嗎?

看了您的test嚇我一跳,趕緊找Memtest 86 3.0版來試試,因為我也是跑DDR420 CL2.0-3-2-5 2.6V,而且也是跑Prime95,Ram Stress test都ok,還好跑Memtest 86也ok
 ,看來CH-5跟BH-5還是有一點差異 To xbox2002mp: 你試著到google 輸入CAS latency,RAS to CAS latency,RAS recharge timing這些字搜尋一下,讀一下這些文章,就大致可以了解RAM是怎麼讀取的,有不懂再上來問

無法通過僅使用test5或test8的重複測試不見得一定是RAM掛了
但是卻代表你的記憶體在該速度下不一定能夠可靠的運作 是求超頻的爽度還是想安心的使用電腦就看自己如何取捨 |
