FSB to RAM Relation

post #1 of 10
Thread Starter 
Something I have always been confused about. Say I set my PC to 365*8 that would give my CPU an OC of about 2920 but what would my RAM be at with a divider of 180. I am not sure how you are suppose to add this all up, as I plan on dropping my multi big time to see what this board will do tonight but I wanna know where my ram is at so I dont screw it up.

Would you just divide the CPU mhz by 180 to get it then move a decimal or what?

When you say 180, i assume you mean 180MHz, so your ram will be at 360MHz DDR.

Correct. But say I OC what the the equation to figure your ram?

Check out the overclockers calculator in my sig. The processors are wildly out of date, but they aren't entirely required. Just fill in the correct information.

It wont start? I tried it on my Laptop just to see but it will not start up. Does the fact that my Laptop is an Intel matter lol?

I would guess that you don't have .net v1.1 installed on your laptop.

Your HTT is 200MHz stock. If you set your RAM at DDR 400 speeds, it's 1:1 with the CPU. When you overclock, the RAM speed will go up on that 1:1 ratio, and thus at an HTT of 365 your RAM speed will be DDR 730. Forget that

Ok, put the RAM on a divider... set it to DDR 333 speeds, or a RAM:CPU = 167:200 = 5:6 divider. With your HTT of 365, the RAM speed will be 365*5/6 = 304, or DDR 608.

Likewise, set it to DDR 266 speeds, and get a 2:3 divider. HTT = 365; RAM speed 365*2/3 = 243, or DDR 486. This might be within reach with good RAM.

And finally, at a 1:2 divider, the RAM speed will be 182.5, or DDR 365 speed.

Thanks Chozart. On the calc will 5:4 be the same as 9/8? Thats my second lowest to 1:1 which is also 180.

Nope, 5:4 is going to leave a little more seperation between FSB and memory speed. I only put in a few standard dividers, however look for an updated version of the calc that will have a custom divider option (due early next year).

Code:
180 Divider = 180/200

            180      X
            ___  = ___       
            200     365 (new fsb)            

365 x 180 = 65700 
65700 / 200 = 328.5
Didn't read the thread, sorry if somebody allready mention that.
