fsb:memory ratio

post #1 of 9
Thread Starter 
Just a quick question:

I can't find the setting in my bios (award) for fsb/memory ratio's. What else could it be called? Memory divider i think it could be, but I can't find that either.

Any one with a similar machine know?

thanks

Try Memclock Index. The default should be 200Mhz setting it lower should do what you want.

EDIT: Sorry, that is for the Phoenix bios. I was thinking my K8N had the same bios, but I guess the SLI version is different.

I cant think of the name for it, but look anything that has 200mhz in it, when you drop it down, you should be able to change it to 133 166 200 ect.

Yep got it Thanks guys

BFRD and Inquisitor you were both right - i dont have memory ratios, just memclock index. It stops the momory going over what its set to.

But if thats the case, will i be able to OC my memory as theres no settings above 200mhz??

When you are overclocking, you typically drop that mem index. going over 200 will have you going over a 1:1. You will only go over a 1:1 if you arnt overclocking very much, or if you have some tccd that will go higher than your chip wants to go. Just to clarify, 200mhz isnt the speed that your ram will run, its the ratio that your ram will compared to your htt. so running at 100mhz divider when your htt is at 300, puts your ram running at 150mhz. you probably know this already, but just incase.

Any helps appreciated; im a bit of a newbie to OC'ing, i just need to get my facts straight.

Still a little confused. 300/100 is 3, not 150.

If my HTT is say 300, and the memclock index 100, then whats the ratio between memory and HTT? 1:2? How do you get 1:2 from dividing by 100

your HTT is 300 say. -if you run a ratio with your fsb:htt set to 1:2 than your memory would be running at 150mhz while your htt is set to 300 -1:2 ratio can be called 100mhz index (assuming that your default value is 200mhz) this is saying that instead of running 200mhz to 200mhz (1:1 fsb:htt) you will be running 100mhz to 200mhz (1:2) now, this ratio is based off of default speed (200mhz), when you raise your HTT, it should keep the same ratio. Ie: 100mhz:200mhz or 150mhz:300mhz. Thats alot to take in, but if you are still having trouble understanding. Go and alter the value of the index, and boot up, open cpuz and see what speed your ram is running at and what speed your htt is set to.
