剛剛看了一下Hardocp的原文
有寫測試設定阿!
SiS645 Memory Settings at 333MHz DDR bus
Soyo P4S set to Turbo = CAS 2
RAS Active Time 6T
RAS Precharge 2T
RAS to CAS 2T
ACT to ACT delay 2T
R/W turn around Fast
write recovery time 1T
VIA KT266A Memory Settings at 266MHz DDR bus
ABIT KR7A = CAS 2
bank interleave 4 bank
precharge to active 2T
active to precharge 5T
active to cmd 2T
command rate 1T
dram que depth 4 level
Intel i850E Memory Settings at PC1066
This board isn't tweakable to the extent that you can know what your settings are.
We did, however, set them as fast as the board would allow.
VIA P4X333 Memory Settings at 333MHz DDR bus
We have new Corsair XMS3000 DDR sticks for this round of Pentium 4 testing.
XMS3000 is without a doubt the most stable and fastest RAM we've seen at extremely aggressive timings
even at 333MHz and a good way beyond.
CAS 2
bank interleave 4, 2T, 5T, 2T, and command rate 1T.
它說850E沒有調整選項,所以只把記憶體調成PC1066
(對了........市售版有嗎??)
喔......忘了說,anandtech也有P4-2.53G的測試
p4 + RDRAM or xp2100+的表現跟Hardocp一樣,只不過anandtech是用1024*768的解析度
http://www.anandtech.com/cpu/showdoc.html?i=1615&p=13
不管解析度是不是寫錯,p4-2.53g領先xp2100+的幅度可說是一樣的
另外x-bit有comanche的測試
由此可知Hardocp應該沒有造假的可能
不管怎麼說VIA在memory interface的功力不可小覷
kt266(沒有"A"喔) ---> kt333的進步幅度驚人
而VIA自己說過P4X266a的memory interface不如kt266a(當然也不如kt333)
所以同樣驚人的進步也可能發生在p4x266a ---> p4x333
不是嗎?
