4:1 Ratio Why?

post #1 of 24
Thread Starter 
I had a 1:1 ratio with 4gb kit but after plugging in my 8gb kit, I am getting a 4:1 ratio. Is this normal? Why and can I get 1:1 again?

what is your FSB? unless you are running an insane FSB, that ratio shouldn't be 1:1. I run 2:1 because my FSB is 250 which puts my ram at 500mhz, which comes to 1ghz final speed. So you need to take your FSB multiply by 4 and then double and that is your ram speed.

My FSB is 200 with my Multiplier set to 20. My ram is at 1600mhz.

if your FSB is 200, and you have 1600 ram, then 4:1 is the ratio you want for your ram to be running at, it puts it right at the 1600 mark. So you are all good to go, if you were running 1:1 before, that means that before, you were running your ram at 400mhz or something.

Post a screenshot of cpu-z memory tab.

It should be fsb/dram 1:4.

I don't have 8gb but it should be the same ratio.

My old ram was set to 1600 in the bios, too. Where can I check on CPU-Z what mhz it's running at?

woops I was putting 4:1 instead of 1:4. You know what I meant. But you look like you are running the correct speed. I wouldn't worry about it.

EDIT: on a side note, just because you set the ram to 1600 doesn't meant it was running that. Kinda like telling a dog to sit, just because you told it to sit doesn't mean it is actually going to do it.

Am I running at 1600mhz now then?
post #10 of 24
802.7mhz x 2 = 1605.4mhz is what you are running at.

All is good,you should bump the NB up to 2400mhz(multi x12) too.
