Ratio

post #1 of 5
Thread Starter 
I am pushing my e2160 a little more (played with the voltages) I managed to squeeze about 1ghz out of it on stock cooler.

I am still new to Intel overclocking and am trying to figure out the ram speed ratio. CPU-Z says am at 2:1. But I read something about Ill have a better overclock with 1:1 ratio. My motherboard bios says I can input a ratio but doesn't lift choices. Ive read the manual but I must of overlooked it and cant find any info on.

My question is this, how do I set it to 1:1 and is it really important.

My ram is set at default in the bios.

There's no evidence that shows that running your ram at 1:1 ratio gives any sort of improvement over other ratios. How to change the ram:fsb ratio will depend on your bios--there should be an option under the RAM menu to specify the effective speed of the RAM--I don't know anything about your bios, so I can't help much there.

you have DDR3 ram right? why would you buy that board and pay a lot for ram if you didn't want to run it at it's full ability? if you want to run your ram at 700mhz you would of stayed with DDR2 right?

point of my post is don't worry about ratio. it means nothing as far as performance. what you should worry about doing is running the ram as fast as you can get it. isn't that the reason you bought ddr3?

As far as I know am running my ram as fast as i can based on my FSB. I thought if the ratio wasn't 1:1 then you arent pushing your ram at full speed.

I bought DDR3 cause I bought this $350 motherboard for 29.99 from newegg. I was looking to go intel and I jumped on it quick. DDR3 was only $170 or so. Little more if not the same as I paid for my 2 x 1GB Gskill HZ. Enough about that.

I do want to push my ram and everything as much as I can with my stock cooler till I go q6600/e8400 and watercool. Then Ill push more.

If am doing something wrong please by all means let me know.

As long as you're running your ram as fast as you can, then you're running it as fast as you can--multiplier (or divider) doesn't matter, as rx7speed said--use whatever ram multi/divider that runs your ram at it's absolute fastest given the FSB you're working with--if you're using a 550fsb (not that you would unless you were using a 6x multi for your CPU), you could still run your RAM at 1:1 since it's fast RAM. If your FSB were below 400 (giving less than DDR 800 speeds on the 1:1 ratio), then running your RAM at 1:1 would not make any sense since the RAM is obviously capable of running much higher than DDR 800 (since you could use a different RAM multiplier that would allow your RAM to run faster than 1x the FSB speed), and you'd want to use, say, a 3.5 RAM multiplier for a 350MHz FSB speed to allow your RAM to run at 1225MHz as opposed to 750MHz with a multiplier of 2x (which would equate to running at 1:1)).

Hopefully that helps clear things up. There's nothing magical about a 1:1 FSB:RAM ratio that gives better performance over a different multiplier that yields the same overall RAM speed (of course then we can get into strappings which is a whole 'nother issue... oy, so much stuff!).

Good luck!
