I can boot a PE based rescue environment and run stress tests and all seems ok but if I try to boot an Ubuntu Linux iso it freezes as with the Intel driver in Windows even if I select the 'safe graphics' option.Īs I wrote this, it got me thinking: Since this freezing is a symptom of too much undervolting, could the Intel driver be doing just that and either the 4790k doesn't like it or my individual example is degraded slightly and can't cope.? I've tried various versions of the Intel driver from Intel, HP and Dell respectively but always get the same results. The result is the same with either: as soon as the Intel video driver is installed everything freezes up within 30 seconds or so but will work in either Safe Mode or with the 'Microsoft Basic Display Adapter' driver installed. Overclocking isn't the aim: I just want the performance increase that this cpu has as standard.


I've found this thread as I have exactly the same problem except I'm testing a 4790k in an HP 800 G1 SFF & a Dell Optiplex 7020 SFF with Windows 10 圆4. Have you had any luck in sorting your problem?
