Vid Scores go down as FSB goes up

[Guest]

Help! I'm runnong a MSI K7T266a Pro 2 with a Asus V8200 deluxe geforce 3 card. What is weird is as I increase my FSB my video bench marks in sysmark 2001 go DOWN ! I get my best scores at 133FSB. I can get the board and Cpu (xp 1800) stable at over 1.8 Ghz but this kills my video score

Sounds like you have your memory timings set to SPD. This will automatically increase your memory timings as you increase fsb. Set your memory to manual select in the bios and try things again.

well do you have any website teaching on how to change the settings of RAM and what does everything means eg. CAS, RAS and etc..

not that i know of off hand.but basically it goes......
In Award bios it is under Advanced- Chipset configuration
You usually get a choice of MANUAL or USER,which you set the parameters yourself. SPD which means it reads a chip on the memory and sets the speed by the manufacturers defaults.
This is how I understand it. If I'm wrong , someone please correct me.
CAS column access strobe
RAS row access strobe
Memory is mapped in rows and columns.
Take the setting 2/2/2/7/9
The first two is the wait time for the FIRST read.After the cpu calls for a memory read
The second two is the wiat time for a consecutive read from the next column.
The third two is the wait time for a consecutive read from the next row.
The 7 is the wait time between memory reads in cpu cycles.
The 9 is the wait time between memory writes in cpu cycles.
Todays bios adjustments are usually 3or2 for SDRAM or 2or2.5 for DDR SDRAM.
The smaller the number the faster the read or write speed.
You are not limited to 2/2/2 or 3/3/3 you can try 3/2/2 or 3/3/2 etc.....
