some tips here for the memory overclocking


1. Dram boot voltage & Dram eventual voltage:

Some module doesn't like too higher voltage during code training . For example : Hynix 1.74volt passed , 1.78volt failed

But u need 1.78 volt to enter os at certain frequency . Then u can set dram boot voltage = 1.74 , dram eventual voltage = 1.78.

It will help you to pass the training and also go into os without any problem.


2. Boot bclk & Eventual Bclk : it is working same as dram boot & eventual . especially great helpful of maximum memory clocking


3. Trdrd is the key of memory performance . Try to keep this one as 4 , even u have to loose others . U will gain more than what u lose .

4. Memory training threshold : This is the special option by Asrock Z87(M) OCF only .

The value of clock is reference by the memory clock which u are aiming .

you can keep auto from 1333 ~3400 Mhz .

But if you try to max out the memory mhz >3400~4400 , u can try to put it from 14~16 . It might do a little bit help .

5. System agent & IO digital & IO analog : each of them has auto rule already.

If u want to put it by urself . System agent maximum value < +0.5 , IO digital <= +0.3 , IO analog <= +0.25

IO digital & IO analog helps maximum memory clock .









So .. boot is for code training , eventual is for booting into os .

Simple and easy .. enjoy it !!
