    <![CDATA[<strong>Author:</strong> <a href="https://forum.asrock.com/member_profile.asp?PF=4050">AhmadNaim93</a><br /><strong>Subject:</strong> 4711<br /><strong>Posted:</strong> 28 Mar 2017 at 3:29pm<br /><br />Hi, is bclk oc still available for bios 7.20? I update to latest bios because I have problem with bios 2.90. when enabling xmp on advance mode it always bsod during having gaming (on easy mode doesnt cause bsod but it bugging me). As of now, i havent had bsod on 7.20.<br /><br />Last night I tried to bclk oc my i5-6400 to 4ghz.On cpuz it stated 4ghz but the multiplier is reduced to below 20 (stock 8-33). Single thread benchmark show the score is similiar to 6700k 4ghz single thread. However the pc felt really sluggish and lagging.<br /><br /><img src="http://i.imgur.com/eR2IIDv.png" border="0" /><br /><br /><br />Edit:Image<span style="font-size:10px"><br /><br />Edited by AhmadNaim93 - 28 Mar 2017 at 6:51pm</span>]]>
