Can't break the 3.0ghz barrier. Help!

[mknwatt]

I have a set of the OCZ's Ram, found that once I changed the CAS to 3 I was able to reach higher OC's. Give these a try

 

On the .5 multplier it changes the RAM MHz. Example 200x10 with RAM on a 200:01/01 divider equals 200Mhz RAM. Now 200x10.5 with RAM at 200:01/01 equals 190 RAM. Here's how it works.

Ceiling function is shown with ][,

eg

]10.2[ = 11

]-6.2[ = -6

]-8.9[ = -8

 

For positive numbers always round up to the nearest whole number.

For negative numbers always round down (its actually still up) to the nearest whole number.

 

Big example

FSB = 290

CPU ratio = 7

DRAM:FSB ratio = 5:6, re-arrange to 6:5 (FSB : DRAM)

 

Using the formula,

Memory Frequency = (FSB x (CPU ratio)) / ] ((CPU rato) x (FSB : DRAM ratio)) [

 

Memory Frequency = (290 x (7)) / ] ((7) x (6/5)) [

 

Work this bit out first

] ((7) x (6/5)) [

 

6/5 = 1.2

 

and that becomes

] (7) x (1.2) [

 

7 x 1.2 = 8.4

 

Now remember the ceiling function, ][

 

]8.4[ = 9

 

Put that back into the main formula

 

Memory Frequency = (290 x (7)) / 9

 

So

Memory Frequency = (290 x 7) / 9

= 225.5Mhz.

 

Good call on getting a new PSU from the Recommended List.

Finally got to 3.0ghz...I'm working on my OCDB entry now. That's all I wanted to accomplish. I will hold off on the new PSU. Now I'm just trying to find the fastest FSB for my memory. Thanks for all of the help guys.

Congrats man....good job...welcome to the club...
