Specs: Windows 7, 32GB
auto 4.2ghz causes bsod so want to go at it manually.

32gb of g.skill 2400mhz

Any step by steps?
Most just say increase multi then up the voltage.
Which voltage etc?

✔ Best Answer
Try 1.3 vcore @ 45 multiplier for 4.5 ghz

Then do a stress test, i prefer intel burn test (30 loops)
If no problems arise you can keep increasing the multiplier in steps of 1
You should be aiming for a max temp of 85 or lower & dont go over 1.4 vcore for haswell

P.S. You may want to set LLC to 5 or higher for stability
P.P.S Here is a Haswell overclocking guide:

Simple solutions are often the best

Cheers Fingers
Did google myself but most of the terms used didn't appear in the asrock bios.

Thanks hidde663
asrock don't use the term vcore

seems I lucked out and didn't get a decent chip :(

seems 4ghz is about my limit

What are your temps?
What cooler are you using?
OC'ing can be a slow process of trial and error. If your temps are not too high then maybe you can get some more out of it. On unstable clock a small core voltage increase can improve stability. I understand that sometimes an increase of ring voltage can improve stability. If you are using a stock cooler then you can get a tower type cooler with copper core and 120mm fan and this will allow higher (to a point) voltages without overheating. Many board mfg's use different terms for the same thing, especially the voltages so Google OC'ing your motherboard and you may find a guide that is more specific to your board. There are also some items to disable in BIOS to improve stability as well.
