Hallo zusammen,
habe hier eure Probleme und Beschwerden ¨¹ber die gerade
neu ausgelieferten DDR466-Module gelesen.
Ich habe mich deshalb direkt mit unserem HQ in Taiwan in Verbindung gesetzt um mehr Infos zu erhalten.
Hier die erste Reaktion :
First of all, let me introduce our testing environment:
Motherboard: GIGABYTE GA-8SQ800 Ultra Rev 1.0
CPU: Intel P4 2.53G (FSB533)
CPU External Frequency: 140MHz (In GA-8SQ800 BIOS setup menu, must set to 140MHz, so that you can choose DDR 466 in DRAM Frequency)
FSB: 560 (Intel FSB = External Frequency X 4)
VGA Card: Winfast A170 DDR 64MB
CPU Voltage: 1.675V
DDR Voltage: 2.7V
OS: Windows 2000 Professional
Testing Software: SiSoft Sandra 2003 SE

How to get better performance with DDR 466?
Lots of Overclockers use DDR 466 to get best performance, but one thing I have to mention: Best performance and Best stability are not easily exist at same time. If you want Best performance, your system may not be stable, vice versa.
In fact, FSB (Front Side Bus) affects memory bandwidth a lot.
We use 2.53G CPU, FSB 560, DDR 466 to make excellent performance, so both of CPU and FSB must be high. In brief, to get nice memory performance needs at least FSB 400.
For our DDR466 is not stable or not good performance in some system, we don¡¯t think it¡¯s because of our memory. Not powerful CPU or not enough FSB will be asynchronous of high-speed memory. As I mentioned, if you have FSB 400 or higher, our DDR 466 will show it¡¯s wonder performance.
Third.
How to get stable system?
If we overclock CPU to reach DDR 466, the CPU may cause unstable system. But DRAM Frequency and FSB will not raise without overclock CPU, what should we do?
In some low-FSB system (maybe less than FSB300), if we use CPU with 133MHz external frequency, maybe we must overclock it to 150MHz to make DDR 466 to choice, and it¡¯s unstable.
Our experience is to cheat the Motherboard:
We use 133MHz CPU, max FSB is 266, but we do jumper setting to 100MHz. So the M/B will think us 100MHz. And then we set CPU external frequency to 116MHz and choose CPU/DRAM ratio to 4X (We test ok on Albatron KX400-8X¡¢Biostar M7VIT Pro¡¢Biostar M7VIK,but not every M/B have these settings and can show right DDR speed (Ex: DDR 466)).
Then you will have stable DDR466 and at least FSB232.
But we strongly recommend you use CPU with 166 MHz external frequency (Max FSB is 333) in your motherboard to make your DDR 466 higher performance.
