Hello, I'm new here and it is my first overclock attempt since celeron days (I think i had a celeron 500 running @ 800 mhz for years... not sure if I remember correctly). Thanks for your guide. It was much more helpfull than every other one I saw.
So I recently bought an asrock p55 extreme with i7 860 and a noctua cooler and I'm aiming for 3.8 Ghz and trying to keep the voltages as low as possible... But I wanted to see where my rig's limit was first so I got it to 4.1 Ghz stable, albeit hot thanks to your guide.
So here's my question: while determining the max bclock I realised that I can get it stable enough @200mhz to sustain 15 minutes of Prime95 with VTT voltage slightly above stock setting (1.23). But as soon as I hit 201Mhz (or more) the mobo refuses to POST and no amount of VTT voltage increase helps and I tried to raise it up to 1.5v (stock setting 1.21v ) + 0.3v like you said?? Is it normal or did I miss something ?
(maybe a cryptic bios safeguard option enabled? but then why allow me to break the 200 Mhz barrier in the first place?)
I am now running @ 182x21 with 1.225 vcore and all the other voltages at stock levels... and it looks stable though I'm still in the early stages of stress testing. Load temperatures do not go over low 70's. Thanks again for the guide. It's the best out there.
