KT880最新消息==果然跟nforce2不一樣==ABIT!!

ABIT is very likely to bring the first ever QBM-supporting platform into the market by releasing its VIA KT880-based mainboard KV7II later this Fall, I learned over AMDBoard.com. The mainboard will utilize the dual-channel core-logic for AMD processors from VIA and support the entire Socket A CPU family. Additionally, the ABIT KV7II is the first actual nearly official confirmation of VIA KT880 existence.

VIA KT880 core-logic was designed by VIA in order to compete with NVIDIA nForce2 for the fastest Socket A chipset ever developed. The company did not need to make a new product from the ground up since it has a dual-channel Pentium 4 chipset called PT880 due to come in Q4 2003. Just like KT880, the core-logic for NetBurst processors supports conventional PC3200, PC2700 DDR SDRAM as well as Quad Band Memory at up to 133MHz (effective 533MHz).

Frankly speaking, because no processor can utilize 8.50GB/s or more memory bandwidth, QBM DRAM is an advantage neither for Intel nor AMD-based systems nowadays. Even though QBM modules may be cheaper compared to high-speed DDR and DDR-II solutions, they are unavailable and may be even more expensive than competing technologies initially.

ABIT’s KV7II mainboards is not too advanced, but still an interesting solutions for good-old AMD Athlon XP processors:

Supports Socket A AMD Athlon XP processors with 200/266/333/400MHz FSB;
VIA KT880 chipset, including VT8237 I/O controller;
3 DIMM slots for up to 3GB of PC2100, PC2700 or up to 2GB of PC3200 memory or QBM533 DRAM; Note that for dual-channel configurations you have to install a pair of identical memory modules;
5/6 PCI slots and 1 AGP 8x slot;
2-channel ATA-33/66/100/133 integrated controller;
2 Serial ATA-150 ports;
10/100Mb/s Ethernet controller from VIA;
6/8 USB 2.0 ports;
6-channel CMedia CMI 9739A audio solution;
Overclocking, tuning, ABIT Engineered functions;
ATX Form Factor.
Pricing and availability information was not touched upon

這個不一樣是指文中提到的QBM:confused: :confused: :confused:
到底能不能非同步我還是看不懂
不過據說PT880可以定頻那KT880如果也可以就很有看頭喔:like:

ABIT 非常可能在今年秋末推出第一張VIA KT880晶片組支援QBM的KV7II主機板搭配VIA晶片組的主機板將對AMD全系列處理器做dual-channel core-logic的最佳化除此之外ABIT的KV7II是第一張最接近官方正式版的KT880晶片組的主機板

VIA所設計的core-logic是為了和目前效能最佳的Nvidia Nforce2晶片組抗衡 VIA可以從自家將在2003 Q4發表的P4晶片組PT880中移植雙通道的技術而不須從零開始如同KT880 支援NetBurst處理器的core-logic一樣是可使用PC3200 PC2700 的DDR SDRAM 和533Mhz(133*4)的記憶體頻寬

坦白的說現今沒有處理器可能完全用到8.5GB/s以上!的記憶體頻寬而QBM對於Intel或AMD處理器都算是現今有較佳優勢的技術雖然QBM對於現今的高速DDR或DDR II的成本較低但因目前還無法取得或售價相對於較高所以無法與現今市面上的產品競爭

ABIT 的KV7II雖不是很先進但對於Althon XP仍是很好的解決方案:

支援 Socket A AMD Althon XP 200/266/333/400 FSB 的處理器

VIA KT880晶片 VT8237 I/O 控制器
3DIMM slot 最大支援3GB的PC2100/2700記憶體 2GB的PC3200記憶體或QBM533 DRAM; 注意:若要使用雙通道必須確認是使用兩條相同的記憶體模組
5/6 個PCI & 1 AGP 8X
兩個ATA-33/66/100/133控制器
2個SATA接頭
10/100Mb/s VIA網路控制器
6/8個 USB接頭
CMI9739A六聲道音效
Overclocking, tuning, ABIT Engineered functions;
ATX Form Factor.

有錯請更正!! thx!!

謝謝連結提供，剛剛去看了一下，
大致上有點認識，不知道對不對，跟大家分享一下：
所謂的QBM533應該是用二條DDR266下去跑的，跟NVIDIA不同的是它能夠利用低時脈的DDR記憶體下去跑，而達到等同於DDR533的頻寬，相形之下NVIDIA的DDR根本是做假的，因為有人可以在NF2平台上用二條DDR266跑出DDR533的頻寬嗎？
此外，CPU跟北橋之間如果是AMD平臺的話，仍受限於二倍外頻時脈的頻寬，於AMD XP規格下最高應該只能跑到400MHZ的頻寬（這一段應該沒有辦法更大了，除非能跑266外頻讓它變成533的頻寬），但是USER相對於NF2晶片，可以用低廉的價格（DDR266）弄出一套記憶體=>北橋533MHZ頻寬，北橋=>CPU400MHZ頻寬的系統…
如果我的認知沒錯的話，那這套系統的C/P值會很高…
不知道我寫的有沒有錯？還有…最近有量產、成品的資料嗎？

剛剛我也翻了一下大概知道一些
裡面提到的QBM技術可以作為nforce2跟KT880的分野
之前猜對了===如果跟nforce2一樣就沒意義了
後者所提供的頻寬才能說是真正的雙通道===有加了QBM才能做到

不過tom說PT880需要ECC的記憶體那KT880:confused: ==希望不要

果真如此以後在K7平台也不用把記憶體超的要死要活了:D :D :D

雙通道技術和 nVidia 沒關係吧...
這邊有對 DDRII ,QBM ,dual channel DDR 做比較,可以看看
