Help setup bios to run DDR PC3200

[FOBulous Bob]

Sup everyone,

Somehow I cant setup my mobo to run a DDR PC3200 at 400Mhz, here is my setup

Albatron KX400+ Pro
AMD XP2000+ cpu "Still locked"
512MB Corsair CMX512-3200C2
ATI Radeon 8500LE
2 80G WD HD
365 Enermax PSU

I changed the jumper JP2 to 2-3, and i tried many settings but best i could do I can go with is:
CPU RATIO: 12.5
CPU CLOCK: 133
DDR:CPU RATIO: 2.50X DDR SPEED=333

DRAM CAS LATENCY: i set it to 2
DRAM COMMAND RATE: 1T

this is the best i could do and for some reason whenever i try change the cpu ratio keeping in mind to keep close the cpu speed of 1667, after i save the setting and boots up, it will go back to default which DDR speed runs at 266.

Can anyone help me with the settings or let me know of a site that can help me figure how to set the bios.

TIA

Just for everyone's info the Albatron KX400+ Pro (http://www.albatron.com.tw/product/KX400_plus.php) is a KT333 motherboard.

You are trying to change the cpu ration when the cpu is still multiplier locked? Why not adjust the DRAM clock? http://www6.tomshardware.com/mainboard/02q3/020814/kt400-03.html

To clarify: can you run the cpu at its default speed and the memory will work at 166Mhz {DDR333}? Yes or no.

DDR400 is not an official standard. It has not shown a big increase compared to DDR333 and getting it to work in some motherboards has been problematic. In fact DDR333 is sometimes better due to the timings being better. In addition some DDR400 modules have not been certified by mobo manufacturers to work with their particular mobo's.

that helped a lot! thanks guys especially to chosenfool...
I got it to run at for now 350Mhz....nothing higher than that...
but not going to quit at this point.

chosenfool, can you link me up with some easy explanation of the timing terms like 7-4-4, 6-3-3, etc.

TIA!

P.S. here is a question for you guys...I ran up the DRAM clock up to 140, but kept the cpu numbers intact. when boot up ....my system jumped from a AMD XP2000+ 1667Ghz to XP2100+ 1.8Ghz....my question is:
will this cause any serious damage and to what?

When you increase the FSB to 140Mhz, your CPU speed changes accordingly (12.5x140Mhz = 1750Mhz). Anytime you run your CPU higher than default speed, you will damage it but I don't think it will harm it much. Right now I'm running my AXP 1700+ @ 1900+ (145Mhz FSB) without any problem. Remember to keep the temperature down so your CPU could last longer. With unlocked CPU, you could increase the FSB to 166Mhz and keep your CPU speed @ 1667Mhz with 10x multiplier. This will set your memory to run @ 400Mhz DDR (2.5x166Mhz = 400Mhz DDR).
