Can't overclock i7-5775C on Z97 Extreme9

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Put an USB stick to an USB2.0 port on the MBO,
enter the UEFI and with the F12 - take screenshots of
every menu and submenu - I don't have an Extreme9
at the moment, so I can't lookup the UEFI options.

Post the images in this topic, so I can see what options are
awayable in this MBO.

Today I worked with an Z97 Extreme6 and a 4790K, OC-ed fine with the L2.00 and L2.10.

	I tried both the p1.60 BIOS you recommended and a L1.81 that the ASRock Support sent me. To no avail. The CPU overclocks to the set multiplier, but will soon downclock to whatever multiplier needed to stay within it's 65W power envelope.

	Try the 1.60, it only cost some time, besides that, its free.

	Yes I did. Bios 1.70. No new version available for me. Resseted the Bios several times to no avail as well. I mean I can see the options that need to be changed (the power limits mentioned) but changing the values has no effects. I think the Bios is simply broken and there are too few users with the i7-5775C.

	Did You update Your EFI to 1.70? You can experiment with the 1.60 too. http://www.asrock.com/mb/Intel/Z97%20Extreme9/?cat=Download&os=BIOS

	Hey, I recently switched from a i7-4790K to a i7-5775C on a ASRock Z97 Extreme9. I'm trying to overclock the processor (like I did with the i7-4790K) but it seems there is some kind of hard TDP limit, as the processor will downclock to stay within it's 65W envelope. How can I circumvent this problem? All I can see is a "Long Duration Power Limit" and a "Short Duration Power Limit" , as well as a "Primary Plane Current Limit", but whatever value I enter, it seems to have to affect to my problem. What exactly do I need to change to get the Broadwell CPU properly overclocked. Best
