FSB:DRAM ratio problem?

post #1 of 6
Thread Starter 
I discovered this a while back, I'm not sure if it's a problem though.

First of all, this is my RAM, Kingston 2GB 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)


Alright... My problem is that I cannot seem to go past certain Frequencies (Mhz) on bigger DRAM:FSB ratios.

I shall explain:


My RAM is now running at 479Mhz 5-5-5-15 2T @ 2:3 (FSB : DRAM), completely stable, I passed memtest 3 times.

BUT, here's the catch, if I use a larger ratio, for instance 3:5 (FSB : DRAM), with the same Frequency and timings, I can't even post, not even BIOS. Resulting In me clearing my CMOS to get back up and running again.


PS: I have no voltage control of any kind.

You should be aiming for a ratio of 1:1... Smaller is definitely better for FSBRAM ratio.

Oooohh.. Never thought of that. Although I do have a 340 FSB wall, But I'll come up of something.

Anyway, you have anyway idea about my problem?

What is the voltage setting for the RAM? Try 1.9v and see what happens?

Try increasing increasing the RAM timings then.
