Z77e-ITX & MV-3V4G3D/US - Not OC Friendly

[andy_d90]

The MV-3V4G3D/US Samsung 30nm RAM is extremely popular with the enthusiast community.

Unfortunately everyone I have spoke to have found that setting this ram at 2133 or above in the bios (every version + beta) of a Z77e-ITX results in a fail to post.

I have two sets of each so I can confirm that this is not a batch problem, both system also use 3570k's.

I have also confirmed that I can easily get 2400+ stable on many other boards using this ram.

I have currently settled for 1866 8-9-9-24 1.525v, but for someones who is using the HD 4000 it is quite a loss in possible performance.

I do hope that a fix comes out for this soon.

Also no response from asrock tech support...

It can only be BIOS that's limiting you,you should be show to run 2133mhz once/if asrock improve the BIOS compatibility

I do hope that asrock can change this in the next bios release .

I've tried every version and both of the beta's bios in the last month.

Everything, even suicidal voltages just to be sure, also confirmed with other users.
