**[Official]]** ASRock z87 OC Formula + (M) Thread

[Splave]

Models:
OC Formula: Standard board, conformal coating, 4-way support
OC Formula A: Same as OC Formula with 802.11AC card
OC Formula M: Mini board, OC's the same minus 4-way support, no OLED disp (Best deal if going 2d and single card only)

Quick Tips
-Air cooling 32m overclocking profile is niiiice.
-Mem profiles are made with normal purchased memory kits not golden samples.
-Conformal on the big board imo is best to be used as a second defense. Eraser is the insulation of choice on that one.
-When overclocking memory if you hang on 00 or if the last code you see is 03, something is set too tight for the frequency you are using.
-Tighter timings are not always faster, play with them one at a time. I could tell you which ones matter but thats half the fun!
-Boot bclk and eventual bclk can take some ease off of training at high speed. This can also allow your RTL and I0-L to sometimes be pulled in tighter when set on auto.
-The same with hynix and BBSE, some kits dont like to train with high volts. If you are max mhz'ing hynix you can use 2.0vdimm boot and 2.3vdimm eventual etc.
-The 3000mhz memory divider at 100bclk is not useable, so use 2933 and bclk or 125 strap.
-When using 125 bclk strap, around 145 bclk you will loose stability and its advisable to switch to 167 strap at that point.

Nick tips

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 !!
