Confused about RAM frequency after OC

post #1 of 14
Thread Starter 
On my BIOS, my FSB is set to 260Mhz (for the CPU) with a multiplier of 12x. The RAM is set to 216MHz.

Yet on CPU-Z, it says the RAM is running at a frequency of 283.7MHz

1. Is this going to kill my DDR500 RAM?
2. How can I bring the frequency down to 250MHz or below without reducing the RAM to below 216MHz in the BIOS?

your RAM should be fine.

I'm guessing you have your ram at a 11:10 ratio or something like that (ram to FSB) that would raise it higher, theres an option in the bios to change this. I would leave it though if it runs fine. Faster is better.

Someone told me in another thread I should be able to run my RAM 1:1 with my CPU/FSB.

Does that mean setting the frequency for my RAM to 250MHz in the BIOS, or does that mean setting it to give a resulting frequency of 260MHz shown in CPU-Z?

Can you explain why I have the RAM set to 216MHz in the BIOS screen, but it displays 283.7MHz in CPU-Z?

Look under the advanced settings tab in your bios and then Under dram config you will see that your divider is like stated above higher than the cpu ...ie...11/10 or 12/11 9/7 what ever it's higher you want 1/1

When you set it to 216mhz, that means it'll be 216mhz when the CPU is at 200mhz.

What you need to do is put it on a divider where the number is lower than 200mhz - what a divider does is divide your FSB by one number and multiply or RAM speed by another, the dividers are set and do not change so it would not tell you that yours would run at 216mhz with a 260mhz FSB

Ah, ok, I understand. So as the FSB increases, it takes the memory frequency with it basically?

Exactly... ...So if you run 1:1 then it's gonna be equal to your fsb...5/6 then a lil' less than your fsb

Yep - 216mhz means that when your FSB is running at 200mhz, your RAM is running at 216mhz.

So its got a ratio of 216:200.

When you change the 200 to 260, you need to update 216 too
